Its easy AF, quick, and the reward is really good. If you don’t know anything about crypto, i highly suggest you learn. It’s still very early and its growing super quick. cryptocurrency has gained a ton of attention in the past couple years and is actually starting to become a real actual currencies (already is, but according to our governments) many different types of crypto is starting to become accepted in a bunch of stores, realtors are taking as payment for a house, and colleges are even accepting as tuition. I started researching bitcoin a short amount of time after Satoshi Nakamoto released it (2009) and bought my first few in 2013 at 15$!! From early 2013 the price was about $11 USD and at the end of 2017, $20,000. But they fell and recovered as the stock market does. But the 24-hour trading Volume today, in 2020 is is INSANE ($20,690,383,231) with an even crazier market cap of $209,783,036,693, which by the middle-end of next month should reach $210 billion, possibly sooner. Its just a really smart investment, buy a little over time. Some analysts are predicting that BTC could reach anywhere from $100k to $1,000,000 for BTC in the next few years. Im not sure exactly where i would name the price in 5 years, but know there is only a limited supply of BTC. They are mined (basically just means that the transactions and blocks on the ledger or blockchain are verified) by sophisticated pieces of hardware called ASIIC miners, or some even use GPU, and CPU in expensive computers. Although CPU mining can be very inefficient anymore as the mathematical calculations and problems the miners need to solve get more and more complicated over time. This, the limited supply, the increasing interest, usability, and need for blockchain technology all add the the idea of BTC reaching such incredibly high futures. Their is a total of 20,999,976 bitcoin and that is it. With a total of 18,517,418.75 in circulation. The last BTC is estimated to be 2140. Big difference from the 18.5M mined in 10 years, right? Thats because of the halving. Anyway, I’m sure you have heard some things about BTC, probably from the media, and if it was, it probably wasn’t good. You probably heard that people buy illegal dangerous stuff off of the “Darknet” and that its completely untraceable. Or that money can be laundered through BTC. But that is hardly partly true for BTC and other cryptocurrencies, and completely true for the USD. While the blockchain doesn’t include any personal information connected to wallets (unless you want it there, or you have the wallet through a service that makes you use personal information, which many services are doing), all transactions can still be tracked and seen by anyone who has an internet connection at https://www.blockchain.com. So if the identity of one of the wallet addresses is known, it would be easier to figure the other out. But for paper, money that cannot be said... completely untraceable, has been prone to money laundering since it’s inception, can be used to purchase various drugs—hookers, guns, dynamite, and even politicians... since its inception, without a trace. The reason not just bitcoin, but i think even more exciting, is just blockchain technology and a host of things that are coming with it. It can be used for tons of things, software and can be built directly into blockchains, they can hold and process data at enormous speeds, while being extremely, extremely secure. More secure in a lot ways than banks. There are tons of new cryptocurrency projects being started everyday. For the most part, all of these projects have some sort of token integrated, because its what powers, and processes the data. If people find the project interesting or a great idea you like you’ll be able to invest in it buy buying/selling, or holding the token/coin. When these projects gain enough traction by like-minded individuals, the coin gains a value. This value can then be exchanged for other crypto, or traded directly for Fiat currencies ($,€,₽,¥,£,₩). For some examples of how wonderful the community is, and reveal what the true nature of blockchain and crypto was founded on, ill list 3 of my favorite crypto projects of 2020 so far along with a little excerpt from the white paper or other:
  1. AIDCOIN: “allows websites to embed a widget into their website and accept donations in any cryptocurrency. Any donated crypto is transferred into AID token, which is also a stable coin. At first, this might seem like not such a good thing but the more I looked into it, the more I realized accepting a stable coin might actually make more sense for a charity as it reduces their risk exposure to volatility.”
  2. BRAVE BROWSER—Privacy Internet Browser: “As far as I’m concerned, keeping people safe and protecting their privacy and security is a noble endeavor. For far too long, giants like Google and Facebook have gotten away with unethical data practices with nothing more than a slap on the wrist. They have been able to spy on their users, abuse their data and use it for whatever purpose they deem fit. Brave Browser is looking to put an end to that through the most secure browser that exists on the market today.” Basically Brave takes on the responsibility of completely protecting privacy and from ads. As an added available option, brave allows you, to watch and look at sponsored ads while you browse. So basically just a stand-in for other browsers ads, but instead you make money WITH brave. You are awarded BAT (Basic Attention Token) for your service. BAT’s are currently at .21¢.
  3. Power Ledger: Last but not least. Power Ledger is probably one of my favorite projects that is actually making a real use-case out of crypto and blockchain. They are aiming to disrupt the energy sector with a heightened focus on renewable energy. Their software allows for three core things: 1. Energy Trading (if you have excess energy from your solar panels, for example, you can trade that to your neighbor through Power Ledger). 2. Environmental commodities trading (to help for the reliable tracking of renewable energy credits). 3. Renewable asset ownership (This will allow people who cannot afford their own renewable energy set-up to invest in fractional ownership). I honestly think Power Ledger is doing God’s work and wish them all the best.
As those projects above outlined, the basic principles behind pretty much every currency and upcoming project i have ever seen is, Trust, Sharing profit with the users who help make it into what it becomes, actual transparency, no central authority (due to decentralization), and lastly i believe it gives opportunity to those who are out if opportunity’s way. This is because it reaches so far, like into oppressive governments and 3rd work countries. Anyways, i hope to have given you a little insight during this read. Crypto has so much potential to fill and has already done so much. Looking forward to seeing where else all of this goes.

7 Ways to Earn LTC/Litecoin ASAP

Earning free Litecoin works similarly to earning free Bitcoin. There are several online platforms that give users free Litecoins for performing small tasks or playing online games.
Let’s explore some of the most popular ways to get free Litecoin.

Earn free Litecoin through reputable faucets

The easiest and most popular way to earn free Litecoin is through a Litecoin faucet. A faucet is a website or an application that gives users free crypto coins for completing simple tasks. These tasks are usually easy tasks like completing some captchas, viewing adverts, or playing simple games.
After completing the microtasks, the faucet will reward you with a small amount of Litecoin (Lithoshi). Litoshi is the smallest unit of Litecoin and 1 Lithoshi is equivalent to 0.000000001 Litecoin.
There are various Litecoin faucets out there, many of them being scam faucets. Before you choose a faucet platform, make sure it’s legit. Here, we will highlight a few of the most popular and reputable ones.
It is safe to mention that you should only register on faucets that integrate micro-wallets like Coinpot. Micro-wallets allow you to collect and combine faucet payments easily.

Litecoin Faucet

Just like the previously mentioned faucet, Litecoin Faucet also allows users to earn free Litecoin by solving captchas. You can earn as much as 2,500,000 Litoshis every hour with no daily limitation on the platform.
The unique feature of Litecoin Faucet is that there is no withdrawal limit. Therefore, you can withdraw any amount of Litecoin.
Faucets are sure ways of earning free Litecoin, but you have to be very careful not to fall victim to scams. Before registering on any faucet, look out for the following:
Online reviews to know if it is legit or scam.
Coinpot or Faucethub micro — wallet integration for easy withdrawal.
Deposit before withdrawal feature — This is a typical feature of scam faucets. Faucets are supposed to be free ways to earn Litecoin without any down payment.
Earnings per hour — earnings from faucets are usually small. If a faucet promises an incredible amount of Litecoin, it is probably a scam or total waste of time.
Litecoins earnings from faucets are usually really small. If your earning expectations are high, this might not be the best option for you. There are more lucrative and legit ways to earn free Litecoin. Read on to learn about the other ways to get free Litecoin.

Litecoin cloud mining

Litecoin mining is one of the oldest ways to get free Litecoin. In recent times, earning profits from Litecoin mining can be a major hassle simply because of the cost of setting up the mining device, the cost of electricity, and many other factors.
With the introduction of cloud mining, you can earn free Litecoin without the headaches involved in setting up mining kits. You can find lots of free Litecoin cloud mining contracts online.
All you need to do is download the software on your device to start earning. These software work by using your device’s memory to generate the Litecoin. Which means the more powerful your device, the more free Litecoin you can earn.
However, some of these free Litecoin software contains malicious scripts that can compromise your security by stealing your data. You should only download mining software with great online reviews.
Back when LTC started, it was possible to mine with a standard computer’s CPU or GPU. Unfortunately, as coins grow in both age and popularity, it becomes harder and harder to mine with low-cost equipment. The days of easy mining are over, but that doesn’t mean you still can’t profit from LTC mining.
There are three ways to begin your LTC mining adventure:
Solo mining
Part of a mining pool
Cloud mining

Litecoin lending

Litecoin lending is one of the most lucrative ways to obtain free Litecoin. You can make money by purchasing some Litecoin and lending others on lending platforms.
Lending platforms like Coinloan.io allow you to make as much as 10.5% ROI by lending your LTC. It means if you lend 100 LTC, you earn free 10.5 LTC within a year without doing anything.
By lending your Litecoin, you are making your money work for you. All you need is a trusted and secure lending platform to start earning free Litecoin with this method.

Wager your Litecoin

Another way to get free Litecoin is by wagering your Litecoin. Gambling is not the best way to earn free Litecoin because 70% of gamblers tend to lose more than what they earn.
No doubt that some people have actually managed to become rich through gambling, this, however, is very rare. So if you are a big risk-taker or you really love gambling, Litecoin gambling is one way to earn free Litecoin.
Crypto gambling websites like fortunejack.com, bitstarz.com, and kingbillycasino.com allow you to wager your Litecoin on various casino games. Crypto gambling is probably the riskiest way to earn free Litecoin, and it is not for the faint-hearted.

Invest In Litecoin​

If you’re looking to invest in Litecoin, it’s important to remember that Litecoin is a currency. This means it doesn’t act like a stock or bond. Instead of buying shares of Litecoin, you are swapping your currency for Litecoin currency.
For example, 1 LTC is equal to about $47 USD today. The goal is for the value of Litecoin to rise, in which case, you could exchange your Litecoins back to dollars (from someone willing to do the exchange).​

Referral Links for Crypto Exchanges

This one is good for those out there with friends that are also crypto savvy. Various exchanges offer affiliate programs where you get paid out for inviting your friends and colleagues onto their platform.
Exchanges like Coinbase offer a one time payment when a new person joins their platform while others like Cryptmixer, for example, gives its members an impressive 50% of the revenue from the new clients they bring in. You can also use their exchange to swap the Bitcoin you receive to Litecoin, making it a great way to earn LTC.

Scav Times(When to Scav on What Maps)

So I've posted here before about how I have a Scav with quite a few high leveled abilities to include Max endurance. I'd like to help those that don't really know or just want more info on Scav Raids. This is just my observations and in no way absolute. All Scav spawn times are averages and based off personal experience.
So you want to Scav in but have no idea where to go? Well it's all about what time of day(irl) and what day it is.
Customs (Spawn between 40 to 25 minutes left in raid)- this map is almost always busy no matter when you scav in but the gear you find can fluctuate on the day of the week. Weekends and nights you'll find a lot more dedicated/chaded folks while during the weekdays during the day you'll find a lot more low levels or rather... Bad players.
Shoreline (spawn between 40 to 35 mins left in raid)- This map is a gold mine for scavs..no matter when. But the gold could be different. Night time (irl again) and weekends you'll roll up on resort and find many bodies(mostly east wing) with good gear just left or find insurance fraud. Weekdays it's a wasteland but that means most caches are unhit.
Interchange (spawn time sub 20 minutes all the way to 10 minutes left) -Scav on interchange and its a race against time. Most battles are done and bodies lay cold. If power has been hit then go to the better known battle spots of kiba or techlight. If no power watch out for Killa. It seems that 7/10 times if power hasn't been thrown Killa still lives. Best times I find to go in for good loot is actually early morning to about noon time on most days. Again the hardcore weekend warriors will always go there but your pickings won't be as good as they'll be teaming more.
Woods (spawn time 40- 30 minutes)- I only ever go to woods if I have a sniper scav. There usually isn't any good loot but often times I find that the middle cabin (with the safe) is not looted. This one is a bit more miss then hit almost everyday.
Reserve(spawn time is 40 -30 minutes)-If you can get past the queue time for reserve it's really not that great. Unless you go as a group be prepared to meet opposition from fellow player scavs and pmc and raiders. This place is always busy and honestly if you're looking to just get gear and get out find a hiding spot and some juice and wait.
Again all of this is based off personal experience from running hundreds of scav runs. I've come out of most raids with gear for my next PmC run quite often and you will be surprised about what places don't get looted. As you can tell most maps are the busiest at night and weekends but if you can scav during the weekdays you'll find the best loot just laying there. I got my Bitcoin farm started from gpu my scav found. Be careful out there and remember take that damn Kolpak off!

GPU or Asic mining

Ok, A little backround. I know hardware and networking. I can build just about any config of a computer. I understand overclocking and undervolting. I can invest around 2,700 for initial investment.
So do I buy hardware to build a GPU miner with at least 6 cards or more? Probably RX580 as they are cheap and I have one in my rig. More on that later.
Or do I a Asic miner like this I understand a GPU miner is multiple coins and not Bitcoin, and Asic is nothing but Bitcoin.
I've done the math on the Asic miner and the ROI in about 3 months with a net gain of about ~10,000 USD a year @ .13 cents per Watt.
I've had a hard time finding a solid or semi way of calculating the earnings for a GPU miner. Not only because it is many coins or dedicated to one coin, but there our other variables involved. However I have more control of the hardware if it fails.
I dipped my toe into mining with my own rig that has a RX580 fatboy and a AMD Phenom ii x4 955 black edition. I overclocked the GPU and undervolted the CPU to reduce heat since it was hitting 62 cel.
The GPU gets 12.5 sol/s and the CPU was getting ~322 h/s. All this added up to ~170 watts and a net of .00218322 BTC/Month. This was all done using Cudo as it was easy to find and setup just to test. This was just a test to see how it would work. I wouldn't use Cudo to full scale as it is a pool and the transfer to a Wallet is pretty steep in relationship to earns. I understand that in a pool you get your share based upon how much of the "work" you did to get find block.
So do I build or buy? With that much computation power do I need to join a pool? What software is best for pool or alone? I am comfortable with CLI as long as it's well documented, but would like a remote GUI.
Also what is the best wallet with the best fees for transactions. Currently using uphold since I use Brave.
I think I covered as much as I could, if you have any questions let me know. Any advice would be great. If I should post this else where let me know please or I could just cross post it.
TIA. Be safe, stay safe!
Edit: Words and BTC earning was WAY off then I first typed this.

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

[HELP] DWM High GPU Usage Even at Power-Saver Plan (No Transparency and Desktop Background, No Background Apps)

[HELP] DWM High GPU Usage Even at Power-Saver Plan (No Transparency and Desktop Background, No Background Apps)
Hi all, I hope someone can help regarding Windows Desktop Manager's high GPU usage.
PC is a prebuild Asus Z240 AIO so I don't have any part customization:
https://www.asus.com/All-in-One-PCs/Zen-AiO-Pro-Z240IC/
I logged in and got a "Preparing your desktop" welcome greeting -- apparently, the PC got updated to version 2004. Upon getting into the desktop, it felt really sluggish and upon checking the Task Manager, DWM is mining bitcoin using a constant 30% of my GPU (see pic 1 & 2). This is at power-saver plan. At normal and high-perf, GPU usage reaches 50%.

What I did so far:
  1. Restart
  2. Disabled startup items (there's not much except for Flexnet license services). Restarted again.
  3. Edited performance options (see pic 3). Removed transparencies, animations, etc.
  4. Removed my desktop background image and set a solid color instead.
  5. chkdsk c: /f
  6. sfc /scannow (twice for good measure)
  7. dism /online /cleanup image /restorehealth (twice again for good measure)
  8. Switched to power saver plan to check if GPU usage would decrease --yes it did... from 50% to 30%.
  9. Downloaded DDU and booted to safe mode -- removed NVIDIA drivers first (no restart after removal) then INTEL drivers (restart after remove)
  10. Upon restarting, Windows redownloaded both INTEL and NVIDIA drivers from Windows Update and prompted for a restart

Hope someone can help me with the high GPU usage.

Or make the PC use the NVIDIA GPU instead, it would be much appreciated. Thanks in advance.

RIP HAL FINNEY "His last post on a BTC Forum"

I thought I'd write about the last four years, an eventful time for Bitcoin and me.
For those who don't know me, I'm Hal Finney. I got my start in crypto working on an early version of PGP, working closely with Phil Zimmermann. When Phil decided to start PGP Corporation, I was one of the first hires. I would work on PGP until my retirement. At the same time, I got involved with the Cypherpunks. I ran the first cryptographically based anonymous remailer, among other activities.
Fast forward to late 2008 and the announcement of Bitcoin. I've noticed that cryptographic graybeards (I was in my mid 50's) tend to get cynical. I was more idealistic; I have always loved crypto, the mystery and the paradox of it.
When Satoshi announced Bitcoin on the cryptography mailing list, he got a skeptical reception at best. Cryptographers have seen too many grand schemes by clueless noobs. They tend to have a knee jerk reaction.
I was more positive. I had long been interested in cryptographic payment schemes. Plus I was lucky enough to meet and extensively correspond with both Wei Dai and Nick Szabo, generally acknowledged to have created ideas that would be realized with Bitcoin. I had made an attempt to create my own proof of work based currency, called RPOW. So I found Bitcoin facinating.
When Satoshi announced the first release of the software, I grabbed it right away. I think I was the first person besides Satoshi to run bitcoin. I mined block 70-something, and I was the recipient of the first bitcoin transaction, when Satoshi sent ten coins to me as a test. I carried on an email conversation with Satoshi over the next few days, mostly me reporting bugs and him fixing them.
Today, Satoshi's true identity has become a mystery. But at the time, I thought I was dealing with a young man of Japanese ancestry who was very smart and sincere. I've had the good fortune to know many brilliant people over the course of my life, so I recognize the signs.
After a few days, bitcoin was running pretty stably, so I left it running. Those were the days when difficulty was 1, and you could find blocks with a CPU, not even a GPU. I mined several blocks over the next days. But I turned it off because it made my computer run hot, and the fan noise bothered me. In retrospect, I wish I had kept it up longer, but on the other hand I was extraordinarily lucky to be there at the beginning. It's one of those glass half full half empty things.
The next I heard of Bitcoin was late 2010, when I was surprised to find that it was not only still going, bitcoins actually had monetary value. I dusted off my old wallet, and was relieved to discover that my bitcoins were still there. As the price climbed up to real money, I transferred the coins into an offline wallet, where hopefully they'll be worth something to my heirs.
Speaking of heirs, I got a surprise in 2009, when I was suddenly diagnosed with a fatal disease. I was in the best shape of my life at the start of that year, I'd lost a lot of weight and taken up distance running. I'd run several half marathons, and I was starting to train for a full marathon. I worked my way up to 20+ mile runs, and I thought I was all set. That's when everything went wrong.
My body began to fail. I slurred my speech, lost strength in my hands, and my legs were slow to recover. In August, 2009, I was given the diagnosis of ALS, also called Lou Gehrig's disease, after the famous baseball player who got it.
ALS is a disease that kills moter neurons, which carry signals from the brain to the muscles. It causes first weakness, then gradually increasing paralysis. It is usually fatal in 2 to 5 years. My symptoms were mild at first and I continued to work, but fatigue and voice problems forced me to retire in early 2011. Since then the disease has continued its inexorable progression.
Today, I am essentially paralyzed. I am fed through a tube, and my breathing is assisted through another tube. I operate the computer using a commercial eyetracker system. It also has a speech synthesizer, so this is my voice now. I spend all day in my power wheelchair. I worked up an interface using an arduino so that I can adjust my wheelchair's position using my eyes.
It has been an adjustment, but my life is not too bad. I can still read, listen to music, and watch TV and movies. I recently discovered that I can even write code. It's very slow, probably 50 times slower than I was before. But I still love programming and it gives me goals. Currently I'm working on something Mike Hearn suggested, using the security features of modern processors, designed to support "Trusted Computing", to harden Bitcoin wallets. It's almost ready to release. I just have to do the documentation.
And of course the price gyrations of bitcoins are entertaining to me. I have skin in the game. But I came by my bitcoins through luck, with little credit to me. I lived through the crash of 2011. So I've seen it before. Easy come, easy go.
That's my story. I'm pretty lucky overall. Even with the ALS, my life is very satisfying. But my life expectancy is limited. Those discussions about inheriting your bitcoins are of more than academic interest. My bitcoins are stored in our safe deposit box, and my son and daughter are tech savvy. I think they're safe enough. I'm comfortable with my legacy.

Building an Ethereum Mining Rig - Part 2

First update to the guide "Building a 6Gpu Mining Rig for Ethereum" - Let's talk about Claymore.
This update supplements and does not replace the Guide to Build a 6GPU Mining Rig for Ethereum published on our site.

The substantial differences are due to the installation of the latest version of the Windows 10 Operating System, the mining on the Ethermine pool (in our opinion simpler than Dwarfpool) and the use of the XFX RX 580 8gb GPUs.

The first variant is found in Part 4 of the guide: the environment variables are not to be entered as they will be integrated directly into the bat file to start mining.

The second variant is found in Part 7 of the guide and leads us to "mine" on a different pool using the Claymore software.
Download the latest version at the following link: https://github.com/Claymore-Dual/Claymore-Dual-Miner

Once downloaded, unzip everything on a folder on your desktop and open the start.bat file with notepad. Clear the contents and copy the following command:

start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker"
EthDcrMiner64.exe

Where instead of "your wallet address" you will have to put your Ethererum wallet - obviously without the quotes - and instead of worker you will put an identification number in case you build more RIGs (such as RIG1, RIG2, etc ...). We opted for the eu1 pool even if some on the discussion forums believe that the us1 is more profitable.

At the following link, many other useful commands for your Rig:
https://github.com/Claymore-Dual/Claymore-Dual-Miner


The Ethermine pool offers a very well crafted and descriptive interface. In the Payouts section, after only 5 minutes of mining, you can decide the minimum amount of Ether to be transferred to your wallet by simply entering the IP address of the RIG.

We have decided to mine directly on the Ethereum address of our Exodus wallet. It is not recommended to mine directly on Coinbase, as reported on the site itself. Sin.

Nothing should be left to chance when you decide to build a mining rig for Ethereum.
The third variant is the most difficult of all. Once you have reached Part 5 of the guide, you can decide whether to continue or follow this update / variant. If you are here it is probably because you have run into some problem that the guide does not allow you to solve.

With the latest version of Windows 10, you may run into a kernel conflict between the operating system and AMD's Radeon Software Crimson ReLive Edition Beta for Blockchain Compute drivers. This conflict will prevent you from using Atiflash after installing the drivers.

Important: Before making any changes to the BIOS, please backup each GPU.

Important: first of all flash the GPUs with the original bios if for any reason you are forced to reinstall the operating system.


Still on Atiflash.
The advice would therefore be to flash the GPUs and then install the AMD drivers. Let's say it would be because you may run into another problem this time related to the GPUs themselves. Since each video card is different from any other, the bios mod of the GPU could crash the operating system showing the classic blue screen and displaying an error related to the Atimkdag.sys file.

This could be due to the fact that some GPUs have significantly higher performance in the calculation phase than others. We could call it a factory overclock but not using them for gaming we cannot say it with absolute certainty.

Having assessed these two drawbacks, the only safe solution is to flash all the GPUs, disconnect them except for the first one, install the Blockchain drivers (plus Atimkdag patch) and launch the mining command verifying that the operating system does not go into crash in the next 5 minutes.

Turn off the rig again and connect the second GPU so on up to the sixth. In the event that one or more video cards should crash the system, disconnect them. After that, it uses DDU from the provisional mode and flashes these GPUs with their original bios. At this point, connect them again, reinstall the Blockcain drivers (plus Atimkdag patch) and start mining definitively.

All the operations related to the use of Atiflash, DDU and driver installation are reported in Part 5 and Part 6 of our guide.
A little bit of Overclocking.
You will certainly find significant differences in performance between the GPUs.

At this point all that remains is to "operate" with an overclocking software. We opt for OverdriveNtool. Our constantly updated guide is available at the following link: https://www.cryptoall.it/2019/10/12/complete-guide-to-overdriventool/

Link to the official YouTube channel for verification: https://www.youtube.com/channel/UCdE9TTHAOtyKxy59rALSprA

GPUs with modified bios will not leave much room for modification. You will have to proceed with the most extreme overclocking on those that mount the original bios; obviously always in small steps by saving the profile for each GPU. Our guide explains in detail how to do it.

Hoping to have been of help, we give everyone an appointment for the second part of the update on how to build an Ethereum mining rig in which we will explain in detail the dual mining on the Ethermine pool.

See you soon.

Filecoin | Development Status and Mining Progress

Author: Gamals Ahmed, CoinEx Business Ambassador
https://preview.redd.it/5bqakdqgl3g51.jpg?width=865&format=pjpg&auto=webp&s=b709794863977eb6554e3919b9e00ca750e3e704
A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

Idea | Tip Nano to creators

Hey guys, my name is Tolik and I'm new to Nano.
I would like to tell you a bit about myself, and then about some ideas that I would like to share with you :)
I'm a content creator form Israel, and I have about 65k subscribers over my 3 channels. I'm also the first Israeli partnered on Twitch and been doing that for 8 years now.
Had a lot of fun with it for the first few years, playing my favorite games and earning good money, and eventually burning out hating the game that got me all my following. Our (Israeli) community exploded on youtube, but to make the most of it you need to make mindless trendy content, playing trendy and pretty childish games. I did that for a while, but it was too hard for my mind and I ended up burning out hard stepping away for a long while.
Back in 2013 I first stumbled upon the world of crypto and realized the potential of the blockchain and the implementation of that technology in our world. Not enough to buy enough to get rich, but I never even considered that it could get to the volumes it got to now. In 2017 when it exploded, I realized I had some leftover coins from 2013-14 and cashed out a few thousand dollars, with the pain it could have been millions if I was a little more aware. Oh Well.
A few years ago, I got into the world of self-development and got a new perspective on life. Doing only what I love and grooming a small but good community on youtube, not caring about trends, views, and money in my pocket.
A few days ago, a colleague of mine started to promote some unknown coin to his child viewers, basically, the premise is a coin that you could mine on your phone. Immediately I had some red flags popping off my mind, especially because he promoted some shady CSGO gambling sites that I didn't even want to look into. He of course had his promotion code for registering to the gambling site, and using the mentioned crypto (downloading the app).
If you can mine it on your phone, what would stop you using an expensive setup and just dominate the market? The fact that he advertised it as a get rich scheme, and the fact that it's a referral pyramid network, does not seem safe.
After looking into it I did not see any promise, especially after I found so many altcoins with big communities that his crypto didn't have, information that did not add up, and a bunch of weird stuff going on.
Because I started researching the crypto world (after so many years not being aware of what happened to it), youtube started suggesting me videos about it, one of them was u/SonderDev 's nanoPaint (Sorry I made SpongeBobs eye red) and started doing some research on nano and the technology. For 3 days I devoured all the info I can, reading most of the posts here on reddit, and joining on Discord and TG. I again felt that butterfly feeling in my gut, the one I felt so many years ago when I found out about bitcoin (and some other rare occasions). So much potential, and I kind of feel I am already late to the party, and yet, my mind can't stop thinking about what is possible.
Now to the good stuff! Donations(tips) to streamers and content creators were always a huge part of our revenue. But we had a lot of problems with it - High fees, making small donations pretty much impossible, and the fear of someone charging you back and having you pay the fees for every donation that got charged back. I had someone give me about $2k for the span of two months with small donations, ended up charging all that money back, and having me pay $10 for each of his donations, even if they were under that amount. PayPal is pretty crazy.
Also, If you consider something like Patreon (a monthly donation for a project or a creator you like for benefits) they also charge extra for their fee, and people can still charge you back, even though they will handle it, you still give them the benefits. Twitch takes a huge cut for subscribers (user pays $4.99 and I get as little as $1.70) and youtube are getting about 30% for their cut.
See where I'm going with this? As proof of concept, a simple donation website/app could be made. You send the creator any amount of nano, it pops up on the screen for everyone to see. People would love the idea to impact the stream with as little money the creator allows. That would start up a conversation, people would start seeing the technology in action, how fast and feeless everything is going.
Not to mention an integrated service could be made that is similar to delegate.it (allows users to do tasks for nano/fiat) in this instance, the tasks could be - follow the creator on Twitter, Instagram, like his posts and whatever else he decides, and it could be cheap, because people would be doing it to pop up on stream and help the creator, not for the actual fiat amount of the nano given. killing 3 birds with one stone. Promoting nano, allowing everybody a voice to a degree they choose, and promoting himself to his viewers.
If this works, we could either go to one of the 2 biggest platforms (StreamLabs and StreamElements (who are Israeli and I know the 2 founders personally)) and they would integrate it to their already build system, or develop something to solely promote nano. We could reach out to smaller streamers that have small dedicated communities, not many donations and revenue coming in and allow them to use our system to promote their content and interact with their viewers.
A few more ideas I have in mind for a project like that:
For the donations (tips)
• Having different donation alerts for different QR codes that you scan. Similarly to what NanoPaint accomplishes, we could have a different QR code to scan for an alert that the user chooses to show up.
• Coloring the Camera frame - similarly to NanoPaint, drawing pixels on the frame of the camera of the streamer, changing it in real-time for nano.
• Having text to speech for the alert
• Have your donation impact the streamer in AR (putting something on his face or head).
Crowd Funding
• Donation goal that will make a purchase only if it gets there - setting up an X day goal to buy a new GPU for example, and having people contribute to it, and if it's reached, it automatically makes the order from amazon or wherever (having the data safe with our service), and if it's not - fully refunding the users. It could be a daily goal for pizza or whatever they choose. It will allow integration with businesses that would work with us.
• Stream goals - if we get to X Nano this stream, 24 hour stream tomorrow! If we won't, get your nano back! Would encourage people to participate even if they are not sure the goal will be met, have the assurance that the full amount would be refunded if it did not get there.
• Challenges - starting a bounty challenge, for example, have an Ace in CSGO (kill all 5 enemies) and get X amount of nano. If you didn't, money goes back. the crowd could vote on it having more interaction and validating if the challenge is complete.
Voting
• Have people engage with polls in real-time with nano, could scan their option to vote, and even get refunded if their option did not win, encouraging them to vote for their favorite option, even if it seems unlikely to win.
User Battles
• Having people start a challenge of a game, in an app or on the web, or perhaps even something random like gambling, and having it appear on stream for everybody to witness. Maybe even challenging the streamer for a nano incentive or someone else who watches.
Chat
• Having an on-screen chat that changes the colors and design of the people who donated with nano, and linked their account. more incentive to donate.
Stream Sponsors
• Having a rotating banner on-screen at all times, allowing users to pay nano to show their banner. As an auction or a price set from the creator.
Most of these ideas occurred to me as I was writing this post, and I'm sure we could think of better ones with some effort. Some of them are already implemented on the websites that were mention above, however, having the power and speed of the nano is a game-changer IMHO.
So why am I writing this post? First, just to share with you and get to know you better, maybe spark an idea or a motivation for anyone to do something good for nano.
Second, money is tight now, moved back to my parents due to the pandemic, hard to find a decent job as we have more than %20 of the people in Israel looking for a job and as I mentioned before the content I make is not very profitable. I can't afford to invest money in this idea, and I lack the skills to do it myself. So maybe if it's good someone else could.
If, however, someone would be inclined to help make this a reality, I would appreciate any comments, suggestions, investment of time, or money in testing this out. I have a dedicated community with thousands of people that will be aware of nano if we'll do it, years of experience in this field, and not to mention that I'm in good relations with most of the other content creators and platforms here in Israel, and some international.

What price of bitcoin is needed to maintain the network safety.

Hi, I am a newbie with very basic understanding of Bitcoin. What I understand roughly:
Bitcoin transaction are secured by blocks. Blocks need to be mined with much compute. If there are too few different miners the security of the network goes down. Miners are rewarded with Bitcoin. To limit the amount of Bitcoin the Bitcoin reward for mining is halved every so and so often.
My question: What I understand it is possible for Bitcoin to increase in value significantly. At the same time Bitcoin is only safe while we have enough miners. With the continued halving of the rewards could the decline in miners compromise the safety of Bitcoin? Has anyone ever done the math with mining capacity of GPU ect. and can tell what minimal USD value Bitcoin needs to hold in the long run (after many halvings) to keep the network safe by financing the mining effort?

A Software Engineer's Explanation of Server Ticks/FPS, the Message Pump, and Server Meshing

Since people liked my last post about the SQ42 report, I thought I would do another about the recent comment about server ticks https://robertsspaceindustries.com/spectrum/community/SC/forum/50259/thread/end-goal-server-tick-rate/2872293
To understand how this works, you must first understand the Message Pump. This is basically the heart beat of an application. It is a loop from which there is no escape, so long as the application runs. All applications have an "entry point" that initially gets called. If you've ever taken Computer Science 101, it would be your "main" function. For a console application, you enter main, it does some things, and then when it leaves main, the application closes. In an application with a graphical user interface, that loop has to regularly call a Render or Draw function that draws the UI. This happens on the Render Thread. In a regular client application your Message Pump will look something like this:
while(IsApplicationRunning) { //loop while application is meant to run HandleKeyboardInputs(); //check to see if any keyboard events have occured HandleMouseInputs(); //check to see if any mouse events have occurred, hittest children HandleSizeChanges(); //check if the window has resized, resize children to fit Render(); //recursively render all child controls } 
Each function call within the loop will call entire hierarchies of functionality. This same basic principal applies to a server as well. I am using my imagination, as I have never audited the Star Citizen codebase, but its message pump would look something like
while(IsServerOnline) { //loop while server is meant to run HandleOrbitalRotation(); //update position of all planets around the sun HandleNPCRoutines(); //update position/animations of all NPCs SynchronizePlayerLocations(); //receive player location packets and update //internal locations CheckForIssues(); //check all object positions and ensure no conflicts UpdatePlayerLocations(); //send new location data of all objects to connected //players } 
This is only the most basic sort of functionality, that doesn't factor in things like Server Object Container Streaming or Meshing or object persistence.
Each iteration of the Message Pump is a frame. These frames are calculated by having a Stopwatch and taking averages of how long it takes each frame to complete across a defined sample size. If you have a target frame rate, like 30fps for instance, subroutines can be prioritized to try to either run on the current frame, or be skipped, based on how much load is put on the servers.
My current understanding, based on Star Citizen's published material, is that there is presently one server for every 50 players, and that server handles an entire star system. Having one server for every 50 players right now is fine, and that number can hopefully be increased as optimizations happen within the code.
The important part is modifying the server code so that they can separate different Object Containers to separate physical server hardware. This would allow them to, for instance, have one server, with its own message pump, handle Port Olisar, for up to 50 players. For v0 of server meshing, I would imagine that, when the 51st player comes to PO, they would have to spin up a new server for that person of PO, and they would be on their own. When the player count goes back below 50, that server can go back to sleep and is available to be repurposed for whatever other area needs it, dynamically. As players leave PO, and go into space, each part of space could have dedicated servers for that area. The same goes for planets, or cities. Each would be its own Object Container, each Object Container could contain smaller Object Containers, so that as players move around, servers would seamlessly spin up or down to host content for the players. Technically, one server could even host multiple separate Object Containers if they both have low player counts.
This would go a very long way towards making the universe feel full and connected. To start out with, you might still only find a maximum of 50 people on Daymar, but you might also find 50 people on Yela, or ArcCorp. Each place could be full, with the game client switching servers when going to different areas. Server Object Container Streaming is what enables this. It is just a matter of handling the trade off between servers, and keeping everything synchronized. I recognize that the posts that CIG makes on the subject are often hard to understand for laymen, but these posts make me feel confident that they are making progress and heading in a meaningful direction toward the end goal of having us seamlessly switch between servers on the fly.
One thing that I have no heard anything about is the transition towards specialized physical hardware for handling some of these large-scale server-side operations. If they are using regular CPU/GPU operations, performance could be *vastly* improved by creating FPGAs or ASICs that could perform calculations with greater alacrity than a GPU could ever hope to. This is the type of hardware used in medical devices, data centers, or bitcoin mining.
I wrote this up purely to help people understand some aspects of software engineer, and no part of it is meant to be so specific that you should interpret it to be exactly how something works. I am trying to provide a high level, easy to understand, idea of some very complex concepts.
If there is any other part of development that you would like me to comment on feel free to @ me with VerdantNonsense :) Stay safe out there.

Why i’m bullish on Zilliqa (long read)

Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analysed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralised and scalable in my opinion.
 
Below I post my analysis why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since end of January 2019 with daily transaction rate growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralised and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. Maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realised early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralised, secure and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in amount of nodes. More nodes = higher transaction throughput and increased decentralisation. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue disecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as:
“A peer-to-peer, append-only datastore that uses consensus to synchronise cryptographically-secure data”.
 
Next he states that: >“blockchains are fundamentally systems for managing valid state transitions”.* For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralised and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimisation on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (>66%) double spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT etc. Another thing we haven’t looked at yet is the amount of decentralisation.
 
Decentralisation
 
Currently there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralised nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching their transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public.They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers.The 5% block rewards with an annual yield of 10.03% translates to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS & shard nodes and seed nodes becoming more decentralised too, Zilliqa qualifies for the label of decentralised in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. Faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time stamped so you’ll start right away with a platform introduction, R&D roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalised: programming languages can be divided into being ‘object oriented’ or ‘functional’. Here is an ELI5 given by software development academy: > “all programmes have two basic components, data – what the programme knows – and behaviour – what the programme can do with that data. So object-oriented programming states that combining data and related behaviours in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behaviour are different things and should be separated to ensure their clarity.”
 
Scilla is on the functional side and shares similarities with OCaml: > OCaml is a general purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognised by academics and won a so called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities safety is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa for Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue:
In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships  
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organisations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggest that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already taking advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, AirBnB, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are build on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”*
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They dont just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities) also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiatives (correct me if I’m wrong though). This suggest in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures & Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!
