Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

d down, k up, everybody's a game theorist, titcoin, build wiki on Cardano, (e-)voting, competitive marketing analysis, Goguen product update, Alexa likes Charles, David hates all, Adam in and bros in arms with the scientific counterparts of the major cryptocurrency groups, the latest AMA for all!

Decreasing d parameter
Just signed the latest change management document, I was the last in the chain so I signed it today for changing the d parameter from 0.52 to 0.5. That means we are just about to cross the threshold here in a little bit for d to fall below 0.5 which means more than half of all the blocks will be made by the community and not the OBFT nodes. That's a major milestone and at this current rate of velocity it looks like d will decrement to zero around March so lots to do, lots to talk about. Product update, two days from now, we'll go ahead and talk about that but it crossed my desk today and I was really happy and excited about that and it seemed like yesterday that d was equal to one and people were complaining that we delayed it by an epoch and now we're almost at 50 percent. For those of you who want parameter-level changes, k-level changes, they are coming and there's an enormous internal conversation about it and we've written up a powerpoint presentation and a philosophy document about why things were designed the way that they're designed.
Increasing k parameter and upcoming security video and everybody's a game theorist
My chief scientist has put an enormous amount of time into this. Aggelos is very passionate about this particular topic and what I'm going to do is similar to the security video that I did where I did an hour and a half discussion about a best practice for security. I'm going to actually do a screencasted video where I talk about this philosophy document and I'm going to read the entire document with annotations with you guys and kind of talk through it. It might end up being quite a long video. It could be several hours long but I think it's really important to talk around the design philosophy of this. It's kind of funny, everybody, when they see a cryptographic paper or math paper, they tend to just say okay you guys figure that out. No one's an expert in cryptography or math and you don't really get strong opinions about it but game theory despite the fact that the topics as complex and in some cases more complex you tend to get a lot of opinions and everybody's a game theorist. So, there was enormous amount of thought that went into the design of the system, the parameters of system, everything from the reward functions to other things and it's very important that we explain that thought process in as detailed of a way as possible. At least the philosophy behind it then I feel that the community is in a really good position to start working on the change management. It is my position that I'd love to see k largely increased. I do think that the software needs some improvements to get there especially partial delegation delegation portfolios and some enhancements into the operation of staking especially.
E-voting
I'd love to see the existence of hybrid wallets where you have a cold part a hot part and we've had a lot of conversations about that and we will present some of the progress in that matter at the product updates. If not this October certainly in November. A lot of commercialization going along, a lot of things going on and flowing around and you know, commercial teams working hard. As I mentioned we have a lot of deals in the pipeline. The Wyoming event was half political, half sales. We were really looking into e-voting and we had very productive conversations along those lines. It is my goal that Cardano e-voting software is used in political primaries and my hope is for eventually to be used in municipal and state and eventually federal elections and then in national elections for countries like Ethiopia, Mongolia and other places. Now there is a long road, long, long road to get there and many little victories that have to begin but this event. Wyoming was kind of the opener into that conversation there were seven independent parties at the independent national convention and we had a chance to talk to the leadership of many of them. We will also engage in conversation with the libertarian party leadership as well and at the very least we could talk about e-voting and also blockchain-based voting for primaries that would be great start and we'll also look into the state of Wyoming for that as well. We'll you know, tell you guys about that in time. We've already gotten a lot of inquiries about e-voting software. We tend to get them along with the (Atala) Prism inquiries. It's actually quite easy to start conversations but there are a lot of security properties that are very important like end-to-end verifiability hybrid ballots where you have both a digital and a paper ballot delegation mechanics as well as privacy mechanics that are interesting on a case-by-case basis.
Goguen, voting, future fund3, competitive marketing analysis of Ouroboros vs. EOS, Tezos, Algorand, ETH2 and Polkadot, new creative director
We'll keep chipping away at that, a lot of Goguen stuff to talk about but I'm going to reserve all of that for two days from now for the product update. We're right in the middle, Goguen metadata was the very first part of it. We already have some commercialization platform as a result of metadata, more to come and then obviously lots of smart contract stuff to come. This update and the November update are going to be very Goguen focused and also a lot of alternatives as well. We're still on schedule for an HFC event in I think November or December. I can't remember but that's going to be carrying a lot of things related multisig token locking. There's some ledger rule changes so it has to be an HFC event and that opens up a lot of the windows for Goguen foundations as well as voting on chain so fund3 will benefit very heavily from that. We're right in the guts of Daedalus right now building the voting center, the identity center, QR-code work. All this stuff, it's a lot of stuff, you know, the cell phone app was released last week. Kind of an early beta, it'll go through a lot of rapid iterations every few weeks. We'll update it, google play is a great foundation to launch things on because it's so easy to push updates to people automatically so you can rapidly iterate and be very agile in that framework and you know we've already had 3500 people involved heavily in the innovation management platform ideascale and we've got numerous bids from everything. From John Buck and the sociocracy movement to others. A lot of people want to help us improve that and we're going to see steady and systematic growth there. We're still chipping away at product marketing. Liza (Horowitz) is doing a good job, meet with her two three-times a week and right now it's Ouroboros, Ouroboros, Ouroboros... We're doing competitive analysis of Ouroboros versus EOS, Tezos, Algorand, ETH2 and Polkadot. We think that's a good set. We think we have a really good way of explaining it. David (David Likes Crypto now at IOHK) has already made some great content. We're going to release that soon alongside some other content and we'll keep chipping away at that.
We also just hired a creative director for IO Global. His name's Adam, incredibly experienced creative director, he's worked for Mercedes-Benz and dozens of other companies. He does very good work and he's been doing this for well over 20 years and so the very first set of things he's going to do is work with commercial and marketing on product marketing. In addition to building great content where hope is make that content as pretty as possible and we have Rod heavily involved in that as well to talk about distribution channels and see if we can amplify the distribution message and really get a lot of stuff done. Last thing to mention, oh yeah, iOS for catalyst. We're working on that, we submitted it to the apple store, the iOS store, but it takes a little longer to get approval for that than it does with google play but that's been submitted and it's whenever apple approves it or not. Takes a little longer for cryptocurrency stuff.
Wiki shizzle and battle for crypto, make crypto articles on wiki great again, Alexa knows Charles, Everpedia meets Charles podcast, holy-grail land of Cardano, wiki on Cardano, titcoin
Wikipedia... kind of rattled the cage a little bit. Through an intermediary we got contact with Jimmy Wales. Larry Sanger, the other co-founder also reached out to me and the everpedia guys reached out to me. Here's where we stand, we have an article, it has solidified, it's currently labeled as unreliable and you should not believe the things that are said in it which is David Gerard's work if you look at the edits. We will work with the community and try to get that article to a fair and balanced representation of Cardano and especially after the product marketing comes through. We clearly explain the product I think the Cardano article can be massively strengthened. I've told Rod to work with some specialized people to try to get that done but we are going to work very hard at a systematic approval campaign for all of the scientific articles related to blockchain technology in the cryptocurrency space. They're just terrible, if you go to the proof of work article, the proof of stake or all these things, they're just terrible. They're not well written, they're out of date and they don't reflect an adequate sampling of the science. I did talk to my chief scientist Aggelos and what we're gonna do is reach out to the scientific counterparts that most of the major cryptocurrency groups that are doing research and see if they want to work with us at an industry-wide effort to systematically improve the scientific articles in our industry so that there are a fair and balanced representation of what the current state of the art are, the criticisms, the trade-offs as well as the reference space and of course obviously we'll do quite well in that respect because we've done the science. We're the inheritor of it but it's a shame because when people search proof of stake on google usually wikipedia results are highly biased. We care about wikipedia because google cares about wikipedia, amazon cares about wikipedia.
If you ask Alexa who is Charles Hoskinson, the reason why Alexa knows is because it's reading directly from the wikipedia page. If I didn't have a wikipedia page Alexa would know that so if somebody says Alexa what is Cardano it's going to read directly from the wikipedia page and you know and we can either just pretend that reality doesn't exist or we can accept it and we as a community working with partners in the broader cryptocurrency community can universally improve the quality of cryptocurrency pages. There's been a pattern of commercial censorship on wikipedia for cryptocurrencies in general since bitcoin itself. In fact I think the bitcoin article is actually taken down once back in, might have been, 2010 or 2009 but basically wikipedia has not been a friend of cryptocurrencies. That's why everpedia exists and actually their founders reached out to me and I talked to them over twitter through PMs and we agreed to actually do a podcast. I'm going to do a streamyard, stream with these guys and they'll come on talk all about everpedia and what they do and how they are and we'll kind of go through the challenges that they've encountered. How their platform works and so forth and obviously if they want to ever leave that terrible ecosystem EOS and come to the holy-grail land of Cardano we'd be there to help them out. At least they can tell the world how amazing their product is and also the challenges they're having to overcome. We've also been in great contact with Larry Sanger.
He's going to do an internal seminar at some point with with us and talk about some protocols he's been developing since he left wikipedia specifically to decentralize knowledge management and have a truly decentralized encyclopedia. I'm really looking forward to that and I hope that presentation gives us some inspiration as an ecosystem of things we can do. That's a great piece of infrastructure regardless and after we learn a lot more about it and we talk to a lot of people in ecosystem. If we can't get people to move on over, it would be really good to see through ideascale in the innovation management platform for people to utilize the dc fund to build their own variant of wikipedia on Cardano. In the coming months there will certainly be funding available. If you guys are so passionate about this particular problem that you want to go solve it then I'd be happy to play Elon Musk with the hyperloop and write a white paper on a protocol design and really give a good first start and then you guys can go and try to commercialize that technology as Cardano native assets and Plutus smart contracts in addition to other pieces of technology that have to be brought in to make it practical.
Right now we're just, let's talk to everybody phase, and we'll talk to the everpedia guys, we're going to talk to Larry and we're going to see whoever else is in this game and of course we have to accept the incumbency as it is. So, we're working with obviously the wikipedia side to improve the quality of not only our article but all of the articles and the scientific side of things so that there's a fair and accurate representation of information. One of the reasons why I'm so concerned about this is that I am very worried that Cardano projects will get commercially censored like we were commercially censored. So, yes we do have a page but it took five years to get there and we're a multi-billion dollar project with hundreds of thousands of people. If you guys are doing cutting-edge novel interesting stuff I don't want your experience to be the same as ours where you have to wait five years for your project to get a page even after government's adopted. That's absurd, no one should be censored ever. This is very well a fight for the entire ecosystem, the entire community, not just Cardano but all cryptocurrencies: bitcoin, ethereum and Cardano have all faced commercial censorship and article deletions during their tenure so I don't want you guys to go through that. I'm hoping we can prove that situation but you know you don't put all your eggs in one basket and frankly the time has come for wikipedia to be fully decentralized and liberated from a centralized organization and massively variable quality in the editor base. If legends of valor has a page but Cardano didn't have one until recently titcoin, a pornography coin from 2015, that's deprecated, no one uses it, has a page but Cardano couldn't get one there's something seriously wrong with the quality control mechanism and we need to improve that so it'll get done.

Introducing Nendly, the Notion-Friendly Forum

Nendly, the Notion-Friendly Forum is a social media site that offers a novel approach to Internet communities.

Overview

Social media today is a poor avenue for Internet conversations. Everyone can have their say, but only in their particular echochamber. While I've written more about it in an essay, go to cc and you'll see the main crux. The things you can talk about here won't fly so well there. Now why is that?
It's because on Reddit, we have a downvote button. And since what you see is based on vote scores, it's essentially a censorship button. If you don't hold a 51% opinion, those in the majority will vote you down, and you'll leave to join another where the electorate is more favorable. And so we get a million insulated communities, each so sure that the others are wrong and needlessly hostile.
But it doesn't have to be this way! Nendly uses a state-of-the-art voting algorithm that enables discussions wherein many competing ideas are possible. Instead of the upvote and downvote buttons being directly tied to what users see, Nendly performs viewpoint analysis to find the best content among a range of diverse beliefs. And since it uses game-theory, there's no possibility for an cc style take-over. You can read more about it here, but basically I've solved the cc problem, as seen in Nendly's much friendlier n/crypto community.
Now there's a lot more to the site, including huge usability improvements and features Reddit doesn't have, but I'll have to leave it for a video I'll put out tomorrow. Ask me any questions and I'll address them then. (I need to sleep, it's been a wild day).

Nano

Ok but why is this a big deal for nano? The benefits are many.
There's more too for nano I'll put in the video. Again, ask me questions and I'll answer them when I'm not so tired :)

Current Progress

There's a lot of features that I'll be releasing over the coming days and weeks that are close to being done. For now, so I could meet the August deadline I set for myself, it's a Desktop-only experience with mobile coming very soon (we've also got a public API that's mostly done, PM me if you want to build an App or something).
So hey, try my site out! You'll find updates coming out very fast since most of the cool stuff is ~90% done. I plan on a major update happening once a week, so it'll be a quick-moving experience if you join our community.
Please bare with me since it's just now public. There's bound to be funny bugs we'll run into, and I already know some email providers are dropping my mail since they've never heard of nendly.com. And who knows, maybe the servers will explode.
Also, I want to say thanks for all the support these past 2 months. I really wanted to give you something you could use before August ended, and thankfully we made it just hours before September!
Edit ok, here’s the video!

Do stocks' prices reflect any intrinsic value anymore?

The value of a stock comes from having voting power over the direction of a company and a claim over its profits, but it seems like most investors never get to vote or claim any dividends and they only buy stocks because they speculate about their future price, and nobody cares about actually voting or having dividends. Just about the price based on the company's reputation.
You can never use the stocks to do anything other than selling them, so it could be argued that they don't have any intrinsic value, couldn't it?
This is specially hypocritical from traditional investors when they say Bitcoin for example doesn't have any intrinsic value. When you at least can use Bitcoin to pay a fee to store data on a decentralized database forever or tranfer value without intermediaries.
What do you think? Can you do something with stocks other than selling them? (with permission of the regulators, exchanges, and brokers, and only during trading days/hours).

For DeFi to grow we need a solution for network congestion, fast

We keep hearing more and more about cases of decentralized projects that are not fundamentally decentralized. We also have an issue where blockchain networks lack any serious interoperability, resulting in almost 0 retail adoptions. If I were to start talking about Ethereum, network congestion, and bottlenecks I might as well go on a long tirade. But what I want to do instead is showcase a possible solution, Fusion.
As you may all know, Bitcoin and Ethereum are heading for old highs since stocks and futures opened green this week. If we are lucky we might get to August price levels at $12k. However, that’s not the only thing that we may get from last month. As you all remember, yield farming is all the craze in this bull run and the heightened activity contributed to a severe bottleneck on Ethereum. We saw how that looked like recently when Uniswap did their $1200 UNI airdrop.
Almost everyone did at least one transaction that day and people had to wait for hours for confirmation. I don’t even have to mention the worst thing, $30 in gas fees for a single transaction. People who don’t have a large portfolio are being ‘scammed’ in fees for making a simple token swap. It’s even worse if you are a small fish and wish to start yield farming. You almost lose more money than you make if you decide to farm.
Fusion fixes this by introducing a fully decentralized cross-chain solution that provides an environment with accessible products and services to the masses. Apart from having special APIs that allow developers to build dApps on the Fusion Network that can communicate with every other network, the protocol also has a great fix for scalability issues. The team introduced a ‘Ticketed Proof of Stake (TPoS) consensus mechanism that secures transactions. Average transaction time needs around 15 seconds for confirmation, supporting 2500 to 3000 TPS.
They also have a custody solution that completely changes decentralization. Their Distributed Control Rights Management (DCRM) technology distributes private key storage to multiple nodes through sharding. In most projects, you’ll see that the devs implemented a centralized server for custody purposes. That kind of model is practically useless as hackers have an easy point of attack.
DCRM is so powerful that many leading cryptologists in the world have approved it. Including experts such as CompSci professor at CUNY Rosario Gennaro, CompSci professor at the University of Versailles Louis Goubin, CryptoExperts CEO Pascal Paillier, and researcher from the department of CompSci at Cornell University Steven Goldfeder.
Fusion already proved its useability to the world with its Anyswap DEX. Anyswap is based on the Fusion network which in return provides farmers with the lowest fees in DeFi. Imagine paying $0.0001 per transaction for a simple token swap on a DEX instead of having to pay up to $40 on Uniswap. The protocol even has a native governance model with the ANY token through which users can bring changes through a voting process. Anyswap is practically what Uniswap would look like if it had a layer 2 scalability solution.
In the end, remember to do your OWN research. But I also have to impose that there is definitely something worthwhile with both Fusion and Anyswap as they offer everything that developers are currently struggling to deliver.

Bitcoin has more intrinsic value than stocks

A common argument thrown by traditional investors is that cryptocurrencies don't have an intrinsic value. The classical example is saying that Bitcoin is not as good as gold because you can build stuff with gold, while Bitcoin's only use is speculation, but I don't find this true at all.
First of all, you can use Bitcoin to pay fees to write into the most decentralized and robust database in history. That by itself has instrinsic value. And second but not less important, you can actually own Bitcoin easily. A lot of investors don't actually possess gold. They posses contracts that say that they own gold “somewhere” with no easy way or no way at all to redeem it. So you usually couldn't due anything with the gold you “own”. You cannot melt it, forge it, or anything.
Same for stocks. They often are not under your name. Heck, sometimes there are not even stocks involved at all. You only have a contract that tracks the price of them. So, a lot of people can't do anything with their stocks other than trading them through intermediaries and during trading hours/days. You usually don't receive a dividend or have a way to vote on the company's direction. Unlike some cryptocurrencies that actually provide you with that and you can actually own by yourself, unlike the gold, stocks, or forex, you probably would never be able to withdrawn (only your balance in a specific asset, not in any other of the assets you allegedly possess).
Yesterday I tried to discuss this on investing, and I got a lot of backlash, with a lot of people missing the point, thinking that I was suggesting buying stocks based on the dividends they offer or something similar, which is far from what I'm saying. So I thought about starting the same discussion in this community to see if the argument lands better or I'm really missing something here.
What do you think?

Hulk.Finance: A Combination of DeFi and High Frequency Trading

DeFi continues to push the limits of blockchain technology. Whether its staking a native token for a second token from the same ecosystem, locking liquidity for an eternity to promote liquidity providing and the benefits of locking tokens, or simply creating new tokenomics that can be tested and studied, DeFi is exploring all avenues to produce the next breakout token such as YFI. Hulk.finance has stepped in to do just that.

Hulk.finance (Contract Address: 0xE1f8CD01aB04b51d02C6fb2BCA61B03fB5e33B99**)** is an ERC20 token which plans to utilize a DAO (Decentralized Autonomous Organization) format that will be community governed in order to promote high frequency trading in a manner only DeFi can bring to the table. As stated on their website, “Our project connects a high-yield partner HFT (High Frequency Trading) fund that has successfully worked from the beginning of 2020 and has year-to-date yields of more than 40%. The fund size is more than 70 millions USD and they operate on several cryptocurrency exchanges like Binance and Bithumb with their API robots. What is good — automated trading does not require continuous uptrend of the Bitcoin price. We have seen good results during Bitcoin breakouts and breakdowns. We want to have the same yields from our investments. But there is a problem — they work with an entrance barrier of 1,000,000 USDT, like many private banking services or high-yield ETFs. Our basic idea is to make a kind of DeFi staking pool and put it under the management of the HFT fund. We will develop all infrastructure for connecting finance flows, deposits, and withdrawals.

The HULK total supply is 100,000 Tokens. Distribution breakdown is as follows:

The project is new but already has a road-map to help guide their lofty ambitions. The first step begins with the formation of the pre-sale and Liquidity pool on Uniswap which is currently ongoing. Secondly, they will distribute Hulk tokens via staking farms. As described in their website they “will run staking farms for farming 80,000 HULKs*. You will need to stake appropriate tokens on the selected farms to get your share of rewards in HULKs. Farm 1 will farm rewards of 60,000* HULKs within 15 days, staking token — ETH-HULK LP Uniswap V2. Farm 2 will farm rewards of 10,000 HULKs within 15 days, staking token — USDN. Farm 3 will farm rewards of 10,000 HULKs within 15 days, staking token — Token Y. Token Y will be announced prior to the farms’ launch. Genesis farming time will be 15 days, after that farming rate will be settled on the level of 15th day. We implement halving every three days, so early farmers will get more HULKs. View on Etherscan. In order to support the price of the token from dumping, we will take a 5% commission for the sale of tokens, when holders sell it on Uniswap, burn 4% and add 1% to the community grants account. The burnt amount will be added to farming pools after 15 days of initial farming. So, for example, if someone sold 20,000 HULKs, we will take 1,000 tokens, burn 800 of them and they will be re-minted on day 16. 200 tokens will be sent to the community grants address. The total supply is 100,000 tokens.”

The third step includes the staking pool. The staking pool will be open for everyone on the following terms and conditions.


Funds from the staking pool will be transferred to the HFT fund for trading operations.

Lastly, the Vault concept is descriptive. “We want to share revenue from HFT fund among HULK holders that stake their tokens in HULK Vault. HFT fund will send revenue from its operation once a month, on the first day of the following month. Current concept: Monthly revenue from HFT operations will be shared between HULK tokens staked in the vault according to the time of staking divided on 720 hours. Example: You stake your 500 HULK tokens in Vault for 20 days (480 hours). Your HULK/hours equal to 500*480=240,000. Total HULK/hours in Vault in this month — 60,000,000. Your share in this month = 0,4%. HFT fund has earned 4% on staking pool funds this month. After payout of their 1,25% (15%/12) per month to USDT stakers, the remaining part is 10,000,000 USDT x 2,75% = 275,000 USD. Your profit share 0.4% of 275,000 = 1100 USDT will be sent as USDT to your address, connected with a Vault.”

All of the above described by the tokens creators seems very complicated, but many tokens are already trying to accomplish this without access to an already built fund which can execute trades on a daily basis. Also due in part is the projects commitment to becoming a DAO by allowing holders to vote on key project decisions and development to make the ecosystem more effective and manageable. Decentralization is the most trustworthy base of contract/cryptocurrency ownership. It creates a unique and secure environment free from direct outside influence due to the filter of the entire community being involved. The developers have said that the voting system for the project will be done within the first 30 days of project launch.

With lofty ambition and high expectations, the project looks to capitalize on the DeFi boom by hedging their fund against the market and giving holders a share of the pie. It will be interesting to see how successful and sustainable the project can be, but we will find out soon enough.

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Monthly Update: Parachute Social Liquidity Pools, Ivan(OnTech) Joins as Advisor, Townhall, Trending on CoinGecko, Covered by EllioTrades Crypto + Altcoin Buzz, …– 31 Jul – 3 Sept'20
Hola folks! Yesterday we got caught up with everything that happened in July 2020 at Parachute and ParJar. Today, I will be sharing news from August. Looking back at those five weeks, they were easily one of the most action-packed ones in the Parachuteverse ever. If you missed my note about the new format from yesterday: “…I thought it would be best to club all the Parachute news into monthly reports and publish them back-to-back over the next few days to catch up with the latest…For a change, we will be focusing on Parachute + ParJar news alone in these monthly reports. Because if we include news from our partner project in these, we might as well publish the Encyclopaedia Britannica”. In case you thought yesterday’s was a long read, boy are you in for a shock today. Make sure to get yourself a beverage and set aside an hour to go through all that will follow. So here’s goes the Parachute scrolls dating 31-Jul-20 to 3-Sept-20 –
31 Jul – 6 Aug'20:
$PAR became one of the top trending coins on CoinGecko this week. The token also received a perfect score on DEXTools. Pretty sweet! We crossed 2500 members in the Parachute channel after quite a while. But no sign of Ron yet. Haha. BrainiacChess Network ($CHESS) was added to ParJar. We got a surprise listing on Hotbit ourselves with an ETH and BTC pairing. $PAR was listed on CoinW exchange this week too. More details here. Looks like wrapping up a day at Parachute usually ends with steaks. If you ever thought otherwise, a look at the $PAR contract should dispel that doubt. A community vote was opened up to list the next token on ParJar. Congratulations to Chirag for winning this week’s Parena and taking home 6k+ $PAR. Neat! Everybody knows about the bitcoin pizza. But did you know about the bitcoin burger? Read all about AlBundy185's crazy BTC journey here. What a wild ride indeed!
AlBundy185’s BTC ride has to be a stuff of legends
Pic of Gian with Diamond Dallas Page taken from his epic WCW Thunder story (https://t.me/parachutetokengroup/395125). Spooky sent us!
Gian announced a temporary stoppage of Two-for-Tuesday to make way for the second annual Big Brother contest. Soon after, he opened up entries for the contest. Woot! Fans can also get updates and spoilers from the GC’s BB group. Gamer Boy hosted a “Random Gk” trivia in TTR this week. Naj hosted a Sunday “Mega Trivia”. Afful held a “General knowledge” trivia as well. Sebastian shared the new ParJar Gaming schedule for August. Yes, you read that right. 75k $PAR in the monthly prize pool. Woot! For this week's Friday creative prompt (#nottodaycovid) by Jason, Parachuters talked "about what you are doing to keep yourself sane during the pandemic" for some cool $PAR.
Alejandro’s betta fish collection is a sight for sore eyes
Elmar, these are all amazing!
Model ships made by Bada during the lockdown. Awesome!
Ivan (from Ivan on Tech) joined the Parachute channel this week. Looks like next few weeks are going to be super exciting! Doc Vic hosted a flash game in the Parachute War Zone for some cool $PAR prizes. Mario had an interesting idea. Change the ParJar display name to “ParJar Wallet” to actually reflect the true nature of ParJar. And voila! “ParJar” is now “ParJar Wallet”. Instant feedback implementation! We also finally got an unofficial price chatter group running. As we mentioned in the last update, Clinton released a limited edition shirt in the Parachute Store this week to commemorate the Liquidity Program on Uniswap. Some of the Parena merch had to be sunsetted from the store though. So if you grabbed some before that, you are now the proud owner of rare Parena merchandise. James from the Parachute Athletics and Running Club announced a Secret Challenge for 400 $PAR. Cap shared a sneak peek into what’s brewing behind the scenes. He also posted some experimental visuals for the website and for ParJar:
Cap’s creative spurts are super trippy! Pt. I
Trippy creatives from Cap Pt. II
7 Aug – 13 Aug'20:
ParJar did some heavy lifting on behalf of Uniswap this week when Uniswap got clogged but ParJar swaps were running smoothly. If you haven’t seen how swaps work yet, CF made another cool video tutorial. Following last week’s community vote, Enjin ($ENJ) won a spot to become the next swappable token on ParJar. DMM DAO’s $DMG token was listed on ParJar as well. Inputs from the community were taken for listing the next DeFi token on ParJar. A new tier was added for the Parachute Uniswap Liquidity Rewards Program this week. Last week’s incredible Parachute run on CoinGecko was noticed by many including DAO Maker and Blockfyre. We got word that Parachute was featured in Ivan’s (Ivan on Tech) private report meant for his closed group of subscribers. Word on the street is that Parachute was reviewed in detail in the Hidden Gems section of the report and received the highest score among all the projects covered there. Super cool! He also talked about Parachute in his latest video. Watch out for timestamps 42:23 and 47:48. And followed it up with another mention in next day’s video as well. Pretty cool! $PAR also saw some crazy movements and activity. And all this started while Cap was chilling on an Amtrack on his way to Vermont. Haha.
Cap shared this amazing view from Vermont
Check out the Sentivate gear in the Parachute shop. For this week's creative prompt (#donkeyart), Jason had Parachuters "find an image of a piece of art that particularly moved" them and explain how and why. Darren’s Mega Friday Trivia in Tiproom had a sweet 6300 $PAR prize pot. Peace Love (Yanni) hosted another quiz in TTR with some more cool $PAR prizes. Clinton’s charity For Living Independence (FLI) became Lumenthropy’s spotlight charity this week which means they will be matching all $XLM donations to FLI. Lumenthropy is Stellar’s charitable arm. The entries to Gian's Big Brother Contest closed this week with Gian starting to share updates on episodes and $PAR rewards to weekly winners. If you want to catch all the action, head over to the BB Group set up by GC. And the most amazing thing happened this week – As new folks were joining into the Parachute group, someone named Ender Wiggin chimed into the chatter and as we talked we figured that he was not only Cap's neighbour in NYC but was also my school senior. Parachute truly brings the world together! PARs & Recreation wants to create a Parachute foodies group. And if his posts are anything to go by (figs, blueberries, Ikura), it’s going to be a hunger-inducing channel. Doc Vic (from Cuba) announced the start of a team Deathmatch tournament in the Parachute War Zone.
Congratulations, Clinton!
Looks like an epic ParJar video is underway. Parachute was also covered extensively by EllioTrades Crypto this week. YouTuber CM TopDog too made an awesome video on Parachute where he talked at length about the project, the roadmap, the token and more. Saweet! After seeing Albundy185 struggle with pooling on Uniswap, Cap and Ice had a light bulb moment for an entirely new feature on ParJar that would make pooling social and fun. More details to be released over the next few weeks.
Jose’s epic new gif puts Cap’s lightbulb moment about social pools into perspective :D
Looks like Alexis’ neighbour is into Uniswap pools as well. Get it, get it? Haha
Congratulations on the new store, Hang! Folks who don't know, Hang is building a hempire. World domination next
14 Aug – 20 Aug'20:
As mentioned last week, Cap and crew had something cool brewing for folks who pool assets on Uniswap. Presenting Social Liquidity Pools (SLP) by Parachute. No more pooling/staking alone in silos. Get together with others doing what you love most – pool assets on Uniswap (either directly or through ParJar - upcoming), then stake the received liquidity tokens into SLPs on ParJar to get additional rewards and social bonuses like entry into VIP or premium token curated groups. Making Uniswap social! Click here to read about what’s next for ParJar and Parachute. The first Uniswap $PAR Liquidity Pool Rewards Program came to a close. All qualified poolers will receive their rewards in 2 months. DeFi superstar yearn.finance ($YFI) was added to ParJar this week for both sends/tips and swaps. Woohoo! Waifu in the house. After last week’s community inputs regarding the next new token on ParJar, a public vote was started. Uptrennd founder Jeff Kirdeikis’ latest project, TrustSwap ($SWAP), got listed on ParJar after winning that vote which got a shoutout from Ivan as well. So now we have a tongue twister on our hands. Haha. Cap also shared the first hints about $PAR governance. More details to be posted next week. Plus, Cap announced that he will be hosting a townhall next week. Stay tuned! Get your questionnaire ready. Like last week, Parachute chatter popped up in Ivan’s latest video this week as well.
Dang! What an amazing place, Victor
For all the mobile gamers out there, Tony set up a Parachute Corporation for the EVE Echoes game. Hit him up if you want to join. Naj hosted a Sunday TTR trivia with a 6300 $PAR prize pot. Gamer Boy held one as well. Darren’s Mega Trivia in Tiproom was super fun as always. Jason did an impromptu token giveaway so that fellow collectors could complete their ParJar collection followed by a mini contest to "guess the closest to the number of miles I am about to run" for some cool $PAR. Chris hosted this week’s creative Friday prompt (#adminfunday): “Using the profile image of any Parachute admin as inspiration, draw what you think that admin would like to do on the weekend”. And what an amazing video Hans (Pad of DeFi Chad). Haha! Super hilarious and fun.
Some of the radest #adminfunday entries. Clockwise from top left: Skittish, TyReal, Staph It!!, Yosma, Ik Now, Jeff, Chica Cuba, Jhang, Kuuraku
21 Aug – 27 Aug'20:
Ivan (from Ivan On Tech) joined Parachute as an advisor. Woot! Welcome to the Parachute fam. Here’s a sneak peek into what the first day discussions with Ivan as an advisor revolved around. The project got featured in France’s largest crypto news platform, Journal du Coin. Noice! Click here for the English translated version. As mentioned earlier, Cap hosted a townhall this week. If you missed it, you can catch up here. He also shared a rough draft snapshot of “how the governance and fee distribution contracts could look for ParJar Wallet”. Plus, some updates from this week and a big picture view at what staking liquidity through ParJar could look like. Parachute also got mentioned in another of Ivan’s videos this week.
Snapshot from the Parachute Townhall
In partnership with Sentivate, ParJar distributed $SNTVT tokens this week to 1500 people of whom 800 were new users. Sentivate hosted this drop for members of a specific group as a token of appreciation for their support. Reminiscent of the AMGO drop, this was a precursor of “how PAR drops + other token drops could work for our Social Liquidity pooling”. The $PAR Governance whitepaper was released and initial brainstorming started in the tokenomics group. Cap was also interviewed by YouTuber Money Party (@Edward_F) this week to talk at length about where we are at and where we are heading. We also received a super duper shoutout from CryptoTube in his latest video where he did a deep dive into ParJar and Parachute. Thanks a ton! Cryptovator did a cool feature on the project as well.
Cap added more changes to the site to show: \"ParJar wallet in action along with…the integrations\" + Big Picture
In this week's creative contest, Jason put up a #writingprompt: "...imagine you are a brand new intern at my new mega corporation...Today is your first day and you are told you need to present something about crypto to upper management...all you know is Bitcoin is a thing and some vague information about it. Pick a coin or general crypto subject and write a short story...None of the facts or material can be correct in your presentation...". Haha! After helping fellow Parachuters with their ParJar collection last week, Jason set up a collector’s group this week. If you have more than 30 of the coins/tokens listed on ParJar in your @parjar_bot collection already, send Jason a PM and he will get you in. Victor hosted a “Big Trivia” in TTR this week for 6300 $PAR in prizes. Afful held a quiz in Tiproom on “General Knowledge” as well. Check out these wicked new shorts in the Parachute Store based on Jose’s gif.
Epic stuff, Jose! Haha
Nice haul from the Parachute Beer Exchange, CF! Markus did you a solid
Boldman Stachs pointed out that $PAR had the highest Galaxy Score on social media analytics platform LunarCRUSH this week. Pretty neat! CF took note. And like Cap mentioned, it has mostly been thanks to him. Haha. And big up to Jesús (@JALBARRAN02) for making a ParJar guide video for our Spanish crew. You rock! Interesting results from the DeFi survey: majority of crypto folks are still DeFi-curious. A new community vote was thrown open for listing the next DeFi token on ParJar. Anyone who's been around a bit already knows that Clinton does some amazing work at his charity, For Living Independence, which creates assistive technology for disabled individuals. This week he shared some snaps of a build which now enables a lady in a wheelchair get upstairs in her home.
This is so wholesome, Clinton! Thank you for doing what you do.
28 Aug – 3 Sep'20:
ParJar was featured in Altcoin Buzz’s latest video. Noice! Click here and here to read some recent updates from Cap. After winning last week’s vote, Akropolis ($AKRO) became the latest token to be listed on ParJar. Woot! bZx crew gave some serious competition too. So we had to get them on ParJar as well. $BZRX was listed this week right after $AKRO. $PAR now has 7k on-chain HODLers. Saweet! Sentivate will be our first partner project to have a Social Liquidity Pool on ParJar. This is amazing! Time for another community vote to get a new project listed on ParJar – this time it is DeFi Pie v/s Ren v/s Proxi DeFi v/s Others. If you’ve missed all the latest Parachute-related videos, we have your back. Check this tweet thread to catch up. Naj hosted a Saturday Tiproom Trivia for 6300 $PAR in prizes. Congratulations to Maria for winning the latest Parena. 8k $PAR in the bag. Woohoo! And congo rats to Yanni as well for winning a special edition shirt from the Parachute store. Gamer Boy’s Big Trivia in TTR saw a ton of participation as always. The Parachute Fantasy Football contest is back! Chris set up the entry rules this week.
CF has done wonders for Parachute’s social metrics: “..+500% in our fi(r)st marketing month..”
Whew, what a month! And with that we close for August 2020 @ Parachute/ParJar. See you again with one more epic monthly update tomorrow. Cheerio!

States and the federal government should not be allowed to enact any restrictions on black powder weapons or ammunition for them. For cartridge firearms, the federal government should only have the power to regulate interstate sale of them. At the state level, cartridge firearms should require a license to obtain.

1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.
