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.

Ramping up community support infrastructure for Ethereum 2 Phase 0: Plugging in

The Medalla Public Multiclient Testnet is well underway, and in a few weeks we'll be looking at the mainnet Eth2 deposit contract and soon after that the Phase 0 genesis block. I'm sure there are a lot of people who are as excited as I am, but what can we do other than wait? We need to build community support infrastructure specific to Eth2.
Let me begin by saying that I'm no one special - I have a background in education and a passion for cryptocurrency, but I'm not here because someone asked me to do this, I'm supporting Eth2 because I think it's the greatest research product of cryptocurrency in the past ten years. Yes - I believe the research product of Eth2 rivals Bitcoin and Ethereum 1.
I want to share my personal vision for an Eth2 support network and how you can get involved with that vision. The benefit to you is the satisfaction of serving others and the enhanced knowledge that comes with being closer to the front lines.
In about ten weeks I predict a 10x increase in the number of new users visiting the /ethstaker reddit and our discord. Many of the new users will be battle hardened skeptics ready to dig deep into the details of Eth2 and many will be technically naive investors who want to stake. What should our support platforms look like when they arrive? Here are some ideas:
  1. New users should know where they can ask questions and get a good response. If people are saying "I don't know if this is the right place to post this..." it means we didn't make them feel welcome quickly enough and they're already wondering if they're going to be welcomed or mocked. We need to find a way to post "ASK QUESTIONS HERE!" in a highly visible place.
  2. We should improve our capacity to quickly respond to questions accurately. I'd love to see us develop a standard procedure of answering questions with a linked source. None of us has all of the answers, but what we can do is validate questions and tag people who can help users get closer to the information they seek.
  3. Our Ethstaker community has earned a brand as being welcoming, let's develop that as we continue to be exhaustively kind to every user.
  4. We can all take more time to learn about the fundamentals of Eth2, I've had great success starting the Eth2-studymaster program and I intend to continue to develop that. If you're not aware of it please check it out - you can earn a POAP for reading about Eth2. Let me know if you want to pitch in somehow.
  5. We need to re-start regularly scheduled community calls. This was my baby and I let it get off track. Let me know if you have the capacity to help schedule those calls and push them forward. I need to update these github notes but they're a good start.
  6. We have a role on discord called "Educator", it includes people like SomerEsat, metanull-operator, Sea Monkey, torfbolt, and strawberrydarling. These are people who consistently provide good support on discord (and often on reddit). I feel like we need to expand this role to 25-50 people by November. Seeing one of these people in the discord room provides an assurance that questions will be addressed in a quality manner.
  7. Go off the rails. Do your own thing. The support network will work best when everyone is supporting other users in the way they're most comfortable - think about what works best for you and go for it.
Here's the bottom line: Eth2 is coming and we have a golden opportunity to enrich and enhance the user base if we decide to make the effort. I hope you'll join us!

All you need to know about Yield Farming - The rocket fuel for Defi

All you need to know about Yield Farming - The rocket fuel for Defi
Source
It’s effectively July 2017 in the world of decentralized finance (DeFi), and as in the heady days of the initial coin offering (ICO) boom, the numbers are only trending up.
According to DeFi Pulse, there is $1.9 billion in crypto assets locked in DeFi right now. According to the CoinDesk ICO Tracker, the ICO market started chugging past $1 billion in July 2017, just a few months before token sales started getting talked about on TV.
Debate juxtaposing these numbers if you like, but what no one can question is this: Crypto users are putting more and more value to work in DeFi applications, driven largely by the introduction of a whole new yield-generating pasture, Compound’s COMP governance token.
Governance tokens enable users to vote on the future of decentralized protocols, sure, but they also present fresh ways for DeFi founders to entice assets onto their platforms.
That said, it’s the crypto liquidity providers who are the stars of the present moment. They even have a meme-worthy name: yield farmers.

https://preview.redd.it/lxsvazp1g9l51.png?width=775&format=png&auto=webp&s=a36173ab679c701a5d5e0aac806c00fcc84d78c1

Where it started

Ethereum-based credit market Compound started distributing its governance token, COMP, to the protocol’s users this past June 15. Demand for the token (heightened by the way its automatic distribution was structured) kicked off the present craze and moved Compound into the leading position in DeFi.
The hot new term in crypto is “yield farming,” a shorthand for clever strategies where putting crypto temporarily at the disposal of some startup’s application earns its owner more cryptocurrency.
Another term floating about is “liquidity mining.”
The buzz around these concepts has evolved into a low rumble as more and more people get interested.
The casual crypto observer who only pops into the market when activity heats up might be starting to get faint vibes that something is happening right now. Take our word for it: Yield farming is the source of those vibes.
But if all these terms (“DeFi,” “liquidity mining,” “yield farming”) are so much Greek to you, fear not. We’re here to catch you up. We’ll get into all of them.
We’re going to go from very basic to more advanced, so feel free to skip ahead.

What are tokens?

Most CoinDesk readers probably know this, but just in case: Tokens are like the money video-game players earn while fighting monsters, money they can use to buy gear or weapons in the universe of their favorite game.
But with blockchains, tokens aren’t limited to only one massively multiplayer online money game. They can be earned in one and used in lots of others. They usually represent either ownership in something (like a piece of a Uniswap liquidity pool, which we will get into later) or access to some service. For example, in the Brave browser, ads can only be bought using basic attention token (BAT).
If tokens are worth money, then you can bank with them or at least do things that look very much like banking. Thus: decentralized finance.
Tokens proved to be the big use case for Ethereum, the second-biggest blockchain in the world. The term of art here is “ERC-20 tokens,” which refers to a software standard that allows token creators to write rules for them. Tokens can be used a few ways. Often, they are used as a form of money within a set of applications. So the idea for Kin was to create a token that web users could spend with each other at such tiny amounts that it would almost feel like they weren’t spending anything; that is, money for the internet.
Governance tokens are different. They are not like a token at a video-game arcade, as so many tokens were described in the past. They work more like certificates to serve in an ever-changing legislature in that they give holders the right to vote on changes to a protocol.
So on the platform that proved DeFi could fly, MakerDAO, holders of its governance token, MKR, vote almost every week on small changes to parameters that govern how much it costs to borrow and how much savers earn, and so on.

One thing all crypto tokens have in common, though, is they are tradable and they have a price. So, if tokens are worth money, then you can bank with them or at least do things that look very much like banking. Thus: decentralized finance.

What is DeFi?

Fair question. For folks who tuned out for a bit in 2018, we used to call this “open finance.” That construction seems to have faded, though, and “DeFi” is the new lingo.
In case that doesn’t jog your memory, DeFi is all the things that let you play with money, and the only identification you need is a crypto wallet.
On the normal web, you can’t buy a blender without giving the site owner enough data to learn your whole life history. In DeFi, you can borrow money without anyone even asking for your name.
I can explain this but nothing really brings it home like trying one of these applications. If you have an Ethereum wallet that has even $20 worth of crypto in it, go do something on one of these products. Pop over to Uniswap and buy yourself some FUN (a token for gambling apps) or WBTC (wrapped bitcoin). Go to MakerDAO and create $5 worth of DAI (a stablecoin that tends to be worth $1) out of the digital ether. Go to Compound and borrow $10 in USDC.
(Notice the very small amounts I’m suggesting. The old crypto saying “don’t put in more than you can afford to lose” goes double for DeFi. This stuff is uber-complex and a lot can go wrong. These may be “savings” products but they’re not for your retirement savings.)
Immature and experimental though it may be, the technology’s implications are staggering. On the normal web, you can’t buy a blender without giving the site owner enough data to learn your whole life history. In DeFi, you can borrow money without anyone even asking for your name.
DeFi applications don’t worry about trusting you because they have the collateral you put up to back your debt (on Compound, for instance, a $10 debt will require around $20 in collateral).
Read more: There Are More DAI on Compound Now Than There Are DAI in the World
If you do take this advice and try something, note that you can swap all these things back as soon as you’ve taken them out. Open the loan and close it 10 minutes later. It’s fine. Fair warning: It might cost you a tiny bit in fees, and the cost of using Ethereum itself right now is much higher than usual, in part due to this fresh new activity. But it’s nothing that should ruin a crypto user.
So what’s the point of borrowing for people who already have the money? Most people do it for some kind of trade. The most obvious example, to short a token (the act of profiting if its price falls). It’s also good for someone who wants to hold onto a token but still play the market.

Doesn’t running a bank take a lot of money up front?

It does, and in DeFi that money is largely provided by strangers on the internet. That’s why the startups behind these decentralized banking applications come up with clever ways to attract HODLers with idle assets.
Liquidity is the chief concern of all these different products. That is: How much money do they have locked in their smart contracts?
“In some types of products, the product experience gets much better if you have liquidity. Instead of borrowing from VCs or debt investors, you borrow from your users,” said Electric Capital managing partner Avichal Garg.
Let’s take Uniswap as an example. Uniswap is an “automated market maker,” or AMM (another DeFi term of art). This means Uniswap is a robot on the internet that is always willing to buy and it’s also always willing to sell any cryptocurrency for which it has a market.
On Uniswap, there is at least one market pair for almost any token on Ethereum. Behind the scenes, this means Uniswap can make it look like it is making a direct trade for any two tokens, which makes it easy for users, but it’s all built around pools of two tokens. And all these market pairs work better with bigger pools.

Why do I keep hearing about ‘pools’?

To illustrate why more money helps, let’s break down how Uniswap works.
Let’s say there was a market for USDC and DAI. These are two tokens (both stablecoins but with different mechanisms for retaining their value) that are meant to be worth $1 each all the time, and that generally tends to be true for both.
The price Uniswap shows for each token in any pooled market pair is based on the balance of each in the pool. So, simplifying this a lot for illustration’s sake, if someone were to set up a USDC/DAI pool, they should deposit equal amounts of both. In a pool with only 2 USDC and 2 DAI it would offer a price of 1 USDC for 1 DAI. But then imagine that someone put in 1 DAI and took out 1 USDC. Then the pool would have 1 USDC and 3 DAI. The pool would be very out of whack. A savvy investor could make an easy $0.50 profit by putting in 1 USDC and receiving 1.5 DAI. That’s a 50% arbitrage profit, and that’s the problem with limited liquidity.
(Incidentally, this is why Uniswap’s prices tend to be accurate, because traders watch it for small discrepancies from the wider market and trade them away for arbitrage profits very quickly.)

However, if there were 500,000 USDC and 500,000 DAI in the pool, a trade of 1 DAI for 1 USDC would have a negligible impact on the relative price. That’s why liquidity is helpful.
You can stick your assets on Compound and earn a little yield. But that’s not very creative. Users who look for angles to maximize that yield: those are the yield farmers.
Similar effects hold across DeFi, so markets want more liquidity. Uniswap solves this by charging a tiny fee on every trade. It does this by shaving off a little bit from each trade and leaving that in the pool (so one DAI would actually trade for 0.997 USDC, after the fee, growing the overall pool by 0.003 USDC). This benefits liquidity providers because when someone puts liquidity in the pool they own a share of the pool. If there has been lots of trading in that pool, it has earned a lot of fees, and the value of each share will grow.
And this brings us back to tokens.
Liquidity added to Uniswap is represented by a token, not an account. So there’s no ledger saying, “Bob owns 0.000000678% of the DAI/USDC pool.” Bob just has a token in his wallet. And Bob doesn’t have to keep that token. He could sell it. Or use it in another product. We’ll circle back to this, but it helps to explain why people like to talk about DeFi products as “money Legos.”

So how much money do people make by putting money into these products?

It can be a lot more lucrative than putting money in a traditional bank, and that’s before startups started handing out governance tokens.
Compound is the current darling of this space, so let’s use it as an illustration. As of this writing, a person can put USDC into Compound and earn 2.72% on it. They can put tether (USDT) into it and earn 2.11%. Most U.S. bank accounts earn less than 0.1% these days, which is close enough to nothing.
However, there are some caveats. First, there’s a reason the interest rates are so much juicier: DeFi is a far riskier place to park your money. There’s no Federal Deposit Insurance Corporation (FDIC) protecting these funds. If there were a run on Compound, users could find themselves unable to withdraw their funds when they wanted.
Plus, the interest is quite variable. You don’t know what you’ll earn over the course of a year. USDC’s rate is high right now. It was low last week. Usually, it hovers somewhere in the 1% range.
Similarly, a user might get tempted by assets with more lucrative yields like USDT, which typically has a much higher interest rate than USDC. (Monday morning, the reverse was true, for unclear reasons; this is crypto, remember.) The trade-off here is USDT’s transparency about the real-world dollars it’s supposed to hold in a real-world bank is not nearly up to par with USDC’s. A difference in interest rates is often the market’s way of telling you the one instrument is viewed as dicier than another.
Users making big bets on these products turn to companies Opyn and Nexus Mutual to insure their positions because there’s no government protections in this nascent space – more on the ample risks later on.
So users can stick their assets in Compound or Uniswap and earn a little yield. But that’s not very creative. Users who look for angles to maximize that yield: those are the yield farmers.

OK, I already knew all of that. What is yield farming?

Broadly, yield farming is any effort to put crypto assets to work and generate the most returns possible on those assets.
At the simplest level, a yield farmer might move assets around within Compound, constantly chasing whichever pool is offering the best APY from week to week. This might mean moving into riskier pools from time to time, but a yield farmer can handle risk.
“Farming opens up new price arbs [arbitrage] that can spill over to other protocols whose tokens are in the pool,” said Maya Zehavi, a blockchain consultant.
Because these positions are tokenized, though, they can go further.
This was a brand-new kind of yield on a deposit. In fact, it was a way to earn a yield on a loan. Who has ever heard of a borrower earning a return on a debt from their lender?
In a simple example, a yield farmer might put 100,000 USDT into Compound. They will get a token back for that stake, called cUSDT. Let’s say they get 100,000 cUSDT back (the formula on Compound is crazy so it’s not 1:1 like that but it doesn’t matter for our purposes here).
They can then take that cUSDT and put it into a liquidity pool that takes cUSDT on Balancer, an AMM that allows users to set up self-rebalancing crypto index funds. In normal times, this could earn a small amount more in transaction fees. This is the basic idea of yield farming. The user looks for edge cases in the system to eke out as much yield as they can across as many products as it will work on.
Right now, however, things are not normal, and they probably won’t be for a while.

Why is yield farming so hot right now?

Because of liquidity mining. Liquidity mining supercharges yield farming.
Liquidity mining is when a yield farmer gets a new token as well as the usual return (that’s the “mining” part) in exchange for the farmer’s liquidity.
“The idea is that stimulating usage of the platform increases the value of the token, thereby creating a positive usage loop to attract users,” said Richard Ma of smart-contract auditor Quantstamp.
The yield farming examples above are only farming yield off the normal operations of different platforms. Supply liquidity to Compound or Uniswap and get a little cut of the business that runs over the protocols – very vanilla.
But Compound announced earlier this year it wanted to truly decentralize the product and it wanted to give a good amount of ownership to the people who made it popular by using it. That ownership would take the form of the COMP token.
Lest this sound too altruistic, keep in mind that the people who created it (the team and the investors) owned more than half of the equity. By giving away a healthy proportion to users, that was very likely to make it a much more popular place for lending. In turn, that would make everyone’s stake worth much more.
So, Compound announced this four-year period where the protocol would give out COMP tokens to users, a fixed amount every day until it was gone. These COMP tokens control the protocol, just as shareholders ultimately control publicly traded companies.
Every day, the Compound protocol looks at everyone who had lent money to the application and who had borrowed from it and gives them COMP proportional to their share of the day’s total business.
The results were very surprising, even to Compound’s biggest promoters.
COMP’s value will likely go down, and that’s why some investors are rushing to earn as much of it as they can right now.
This was a brand-new kind of yield on a deposit into Compound. In fact, it was a way to earn a yield on a loan, as well, which is very weird: Who has ever heard of a borrower earning a return on a debt from their lender?
COMP’s value has consistently been well over $200 since it started distributing on June 15. We did the math elsewhere but long story short: investors with fairly deep pockets can make a strong gain maximizing their daily returns in COMP. It is, in a way, free money.
It’s possible to lend to Compound, borrow from it, deposit what you borrowed and so on. This can be done multiple times and DeFi startup Instadapp even built a tool to make it as capital-efficient as possible.
“Yield farmers are extremely creative. They find ways to ‘stack’ yields and even earn multiple governance tokens at once,” said Spencer Noon of DTC Capital.
COMP’s value spike is a temporary situation. The COMP distribution will only last four years and then there won’t be any more. Further, most people agree that the high price now is driven by the low float (that is, how much COMP is actually free to trade on the market – it will never be this low again). So the value will probably gradually go down, and that’s why savvy investors are trying to earn as much as they can now.
Appealing to the speculative instincts of diehard crypto traders has proven to be a great way to increase liquidity on Compound. This fattens some pockets but also improves the user experience for all kinds of Compound users, including those who would use it whether they were going to earn COMP or not.
As usual in crypto, when entrepreneurs see something successful, they imitate it. Balancer was the next protocol to start distributing a governance token, BAL, to liquidity providers. Flash loan provider bZx has announced a plan. Ren, Curve and Synthetix also teamed up to promote a liquidity pool on Curve.
It is a fair bet many of the more well-known DeFi projects will announce some kind of coin that can be mined by providing liquidity.
The case to watch here is Uniswap versus Balancer. Balancer can do the same thing Uniswap does, but most users who want to do a quick token trade through their wallet use Uniswap. It will be interesting to see if Balancer’s BAL token convinces Uniswap’s liquidity providers to defect.
So far, though, more liquidity has gone into Uniswap since the BAL announcement, according to its data site. That said, even more has gone into Balancer.

Did liquidity mining start with COMP?

No, but it was the most-used protocol with the most carefully designed liquidity mining scheme.
This point is debated but the origins of liquidity mining probably date back to Fcoin, a Chinese exchange that created a token in 2018 that rewarded people for making trades. You won’t believe what happened next! Just kidding, you will: People just started running bots to do pointless trades with themselves to earn the token.
Similarly, EOS is a blockchain where transactions are basically free, but since nothing is really free the absence of friction was an invitation for spam. Some malicious hacker who didn’t like EOS created a token called EIDOS on the network in late 2019. It rewarded people for tons of pointless transactions and somehow got an exchange listing.
These initiatives illustrated how quickly crypto users respond to incentives.

Fcoin aside, liquidity mining as we now know it first showed up on Ethereum when the marketplace for synthetic tokens, Synthetix, announced in July 2019 an award in its SNX token for users who helped add liquidity to the sETH/ETH pool on Uniswap. By October, that was one of Uniswap’s biggest pools.
When Compound Labs, the company that launched the Compound protocol, decided to create COMP, the governance token, the firm took months designing just what kind of behavior it wanted and how to incentivize it. Even still, Compound Labs was surprised by the response. It led to unintended consequences such as crowding into a previously unpopular market (lending and borrowing BAT) in order to mine as much COMP as possible.
Just last week, 115 different COMP wallet addresses – senators in Compound’s ever-changing legislature – voted to change the distribution mechanism in hopes of spreading liquidity out across the markets again.

Is there DeFi for bitcoin?

Yes, on Ethereum.
Nothing has beaten bitcoin over time for returns, but there’s one thing bitcoin can’t do on its own: create more bitcoin.
A smart trader can get in and out of bitcoin and dollars in a way that will earn them more bitcoin, but this is tedious and risky. It takes a certain kind of person.
DeFi, however, offers ways to grow one’s bitcoin holdings – though somewhat indirectly.
A long HODLer is happy to gain fresh BTC off their counterparty’s short-term win. That’s the game.
For example, a user can create a simulated bitcoin on Ethereum using BitGo’s WBTC system. They put BTC in and get the same amount back out in freshly minted WBTC. WBTC can be traded back for BTC at any time, so it tends to be worth the same as BTC.
Then the user can take that WBTC, stake it on Compound and earn a few percent each year in yield on their BTC. Odds are, the people who borrow that WBTC are probably doing it to short BTC (that is, they will sell it immediately, buy it back when the price goes down, close the loan and keep the difference).
A long HODLer is happy to gain fresh BTC off their counterparty’s short-term win. That’s the game.

How risky is it?

Enough.
“DeFi, with the combination of an assortment of digital funds, automation of key processes, and more complex incentive structures that work across protocols – each with their own rapidly changing tech and governance practices – make for new types of security risks,” said Liz Steininger of Least Authority, a crypto security auditor. “Yet, despite these risks, the high yields are undeniably attractive to draw more users.”
We’ve seen big failures in DeFi products. MakerDAO had one so bad this year it’s called “Black Thursday.” There was also the exploit against flash loan provider bZx. These things do break and when they do money gets taken.
As this sector gets more robust, we could see token holders greenlighting more ways for investors to profit from DeFi niches.
Right now, the deal is too good for certain funds to resist, so they are moving a lot of money into these protocols to liquidity mine all the new governance tokens they can. But the funds – entities that pool the resources of typically well-to-do crypto investors – are also hedging. Nexus Mutual, a DeFi insurance provider of sorts, told CoinDesk it has maxed out its available coverage on these liquidity applications. Opyn, the trustless derivatives maker, created a way to short COMP, just in case this game comes to naught.
And weird things have arisen. For example, there’s currently more DAI on Compound than have been minted in the world. This makes sense once unpacked but it still feels dicey to everyone.
That said, distributing governance tokens might make things a lot less risky for startups, at least with regard to the money cops.
“Protocols distributing their tokens to the public, meaning that there’s a new secondary listing for SAFT tokens, [gives] plausible deniability from any security accusation,” Zehavi wrote. (The Simple Agreement for Future Tokens was a legal structure favored by many token issuers during the ICO craze.)
Whether a cryptocurrency is adequately decentralized has been a key feature of ICO settlements with the U.S. Securities and Exchange Commission (SEC).

What’s next for yield farming? (A prediction)

COMP turned out to be a bit of a surprise to the DeFi world, in technical ways and others. It has inspired a wave of new thinking.
“Other projects are working on similar things,” said Nexus Mutual founder Hugh Karp. In fact, informed sources tell CoinDesk brand-new projects will launch with these models.
We might soon see more prosaic yield farming applications. For example, forms of profit-sharing that reward certain kinds of behavior.
Imagine if COMP holders decided, for example, that the protocol needed more people to put money in and leave it there longer. The community could create a proposal that shaved off a little of each token’s yield and paid that portion out only to the tokens that were older than six months. It probably wouldn’t be much, but an investor with the right time horizon and risk profile might take it into consideration before making a withdrawal.
(There are precedents for this in traditional finance: A 10-year Treasury bond normally yields more than a one-month T-bill even though they’re both backed by the full faith and credit of Uncle Sam, a 12-month certificate of deposit pays higher interest than a checking account at the same bank, and so on.)
As this sector gets more robust, its architects will come up with ever more robust ways to optimize liquidity incentives in increasingly refined ways. We could see token holders greenlighting more ways for investors to profit from DeFi niches.
Questions abound for this nascent industry: What will MakerDAO do to restore its spot as the king of DeFi? Will Uniswap join the liquidity mining trend? Will anyone stick all these governance tokens into a decentralized autonomous organization (DAO)? Or would that be a yield farmers co-op?
Whatever happens, crypto’s yield farmers will keep moving fast. Some fresh fields may open and some may soon bear much less luscious fruit.
But that’s the nice thing about farming in DeFi: It is very easy to switch fields.

What unites Bitcoin, gold, and Apple shares? — TkeyNet

https://preview.redd.it/ctpbqg8jbjg51.png?width=700&format=png&auto=webp&s=f7337e416de7124455dd5d072b5ee529067af6b3
Today we will briefly review the main points that will clarify the upcoming changes in the TKEY project.
If you missed previous publications about TkeyNet, be sure to read them:

Future changes to the TKEY project

TKEY Asset

Just like the first Protocol (Core 1.0), the TKEY asset used in the TkeyNet network — there are no changes in this plan. After launching TkeyNet, you can transfer TKEY to any user on the TKEY network without any restrictions.

Quick transactions

Transactions in TkeyNet will be much faster than it was before. You can check it in practice.

TkeyConnect Module

The Protocol has a built-in TkeyConnect module, which allows you to connect various blockchains to our network to conduct transactions directly in the TkeyNet blockchain. Besides, TkeyConnect meets the international ISO and ISIN standards, which also allows you to conduct transactions with Fiat currencies and shares in the TkeyNet blockchain.
TkeyConnect creates a flexible system, giving users the ability to store and conduct transactions in any assets, be it Bitcoin, Ethereum, Litecoin or dollars, euros, etc.

New software

If the previous software based on the Core 1.0 Protocol, after switching to TkeyNet, wallets, a blockchain search engine, and other software related to the project will be adapted to the new Protocol.

Contact information and support service

Email addresses of the support service and other departments will be transferred to other service providers and will structure in the following areas: B2B and B2C. The list of email addresses will publish after updates are complete.
B2B (business-to-business) a term that means that a company or a division of a company sells its goods/services to corporate clients, that is, to other companies. B2C (business-to-consumer) is a term that refers to the commercial relationship between an organization (Business) and a private, so-called “end” consumer.

Websites

Information about the project, the company, and its products will subdivide into two websites: tkeycoin.com and tkey.org. The purpose of this division is to simplify product navigation, improve the appearance of pages for each product and solution, and update content.
The solution is modular. The information will be structured according to sections and sites, dividing the corporate and user segments. As the products develop, the information will be updated.
Technical specifications, documentation, and a description of the Protocol and its features will appear on the official website: tkey.org. Sections will fill in gradually.

Testing and launching TkeyNet

Between July 22 and July 24, Telnet was successfully launched in testnet mode. Our team is actively testing the entire TkeyNet network and its functions. The system is tested with different scenarios, its effectiveness is checked when working with high loads, and the security of the entire system is audited. Testing of TkeyNet is an important stage of production aimed at detailed research of the program code and identification of errors in the system operation. Comprehensive testing, which is carried out by our team, is necessary to determine the level of readiness of the system for subsequent operation. Testing is based on a set of test scenarios that cover the main business operations.
The testing process contains all the life cycle activities: dynamic and static indicators. The testing process involves planning, preparing, and evaluating a software product. The purpose of testing is to determine that all meet the requirements described, as well as to show that they are suitable for the stated purposes and for detecting errors.

The Digital Asset Exchange

After launching TkeyNet — we will publish the start date of trading on the exchange. Information is available in the official notification: https://tkeycoin.com/en/news/.
https://preview.redd.it/moap4drobjg51.png?width=700&format=png&auto=webp&s=3fbb1ac32741806c8c2c59081e5e14266ac9a2fe

FAQ

Buying and selling TKEY

You can buy or sell TKEY only on the exchange and not in any other source. Private transactions are subject to high risks. Once again, we remind you that at the time of updates, any transactions with TKEY will be invalid.

Safety of funds

If you use a local wallet on your computer, make a backup copy of the wallet.dat file. If you use a TkeySpace mobile wallet, make a backup copy of the private key (backup phrase).

Transactions before updates are completed

During updates-no transactions can be made on the network, which means that any private dealing made at the time of updates will be invalid. Additionally, we ask you to refrain from any actions related to TKEY until the end of updates protocol, including starting mining, local wallets, and reinstalling them.

Epilogue

Testing of the system and its functions takes place in a stable mode without days off. The test results that will receive at the end of this week will reflect the current state of Affairs. We will get up-to-date information about the end date of updates and the planned release date of TkeyNet.
An announcement of interim test results, as well as future updates, will be published at the end of this week or early next.

CoinEx Token Rating Report by TokenInsight

CoinEx Token Rating Report by TokenInsight
Written by TokenInsight
Published by tokenin.cn

EXECUTIVE SUMMARY

Advantages

  1. The team’s overall technical background is good, and the CTO and CEO of the project have rich experience in related industries;
  2. The current business scope of CoinEx has been expanded, and the development of the public chain has a decisive role in promoting the development of the exchange business;
  3. The project operation information is transparent, and the development process is consistent with the road map;
  4. The unlocking schedule is clear, and the token held by the team will be unlocked continuously in the next five years;
  5. The project uses POS consensus mechanism. At present, it has been launched on the main network, and the block time is stable, between 2–3 seconds.

Challenges

  1. It is not clear enough yet whether the trichain operation planning can achieve the project’s development goals;
  2. There is limited information on implementation details about cross-chain and other related technologies, and the development status needs to be assessed based on the later project development disclosure information;
  3. The team currently hold a large share of the token, hence the distribution of tokens is relatively concentrated;
  4. There are few application scenarios for project tokens, and more ecosystem scenarios need to be developed;
  5. As a deflationary token, CET needs to be balanced by dealing with the contradiction between public chain users and token holders.

Outlook

The development of CoinEx Chain contributes to the future development of CoinEx’s centralized and decentralized exchanges; the concept of trichain operation simplifies the functions of each chain, improving their performance. At present, there are few exchanges working on the public chain, and no fierce competition has occurred.

Conclusion

Considering the status and development prospects of the project, TokenInsight gives CoinEx a rating of BB with a stable outlook.

1. Multidimensional evaluation


2. Project analysis

CoinEx (CoinEx Technology Limited) was established in December 2017 and is headquartered in Hong Kong, China. It is a sub-brand of the ViaBTC mining pool. At present, CoinEx’s business scope includes CoinEx exchange, CoinEx public chain, and CoinEx decentralized exchange. The current development focus of the CoinEx platform are public chain and exchange. The main purpose of the public chain is to build a decentralized exchange (DEX) infrastructure and an ecosystem around DEX.

CoinEx business structure,Source: CoinEx; TokenInsight

2.1 Introduction

“ CoinEx Chain uses the parallel operation of three chains which are DEX, Smart, and Privacy, as well as cross-chain technologies to create a rich decentralized exchange ecosystem and blockchain financial infrastructure.
The core of CoinEx’s early business was the exchange, consisted of two major categories which were spot and derivatives trading. Currently, there are 123 trading currencies online, covering 302 trading pairs. On June 28, 2019, CoinEx released the CoinEx Chain public chain white paper, aiming to build a decentralized trading system (CoinEx DEX) with community-based operations and transparent transaction rules, and providing user-controlled asset trading scenario by the highest technical standards in the industry; CoinEx Chain has become another development focus of CoinEx. CoinEx Token (CET), which was originally a native token of the CoinEx exchange, will also be developed mainly as a built-in token of the public chain.
CoinEx Chain is a public chain based on the Tendermint consensus protocol and Cosmos SDK, and it uses POS mechanism. CoinEx Chain plans to support 42 nodes when the project starts, and any entity in the ecosystem can participate in the validator’s campaign by staking CET. CoinEx Chain will use the new block reward and the transaction fee contained in the block as the reward for running the node.
CoinEx Chain has developed three public chains with different positioning and different functions in order to meet the needs of blockchain transactions for transaction performance, smart contracts, and privacy protection at the same time. They operate in parallel and collaborate with each other through cross-chain technology. At present, the block time of the public chain is between 2–3 seconds. According to the observation of TokenInsight, the block time is stable, but the number of transactions through the CoinEx public chain is still low at present, the number of transactions in 24 hours is about 30,000; The TPS on public chain disclosed by CoinEx can reach up to 1500 per second.
CoinEx Chain uses a trichain parallel model to build a more vibrant ecosystem around DEX. The three chains are DEX public chain, Smart public chain, and Privacy public chain, respectively responsible for decentralized transactions, smart contracts, and on-chain privacy protection.
CETs that need to participate in complex financial contracts can be transferred to the Smart public chain through the DEX public chain, then moved back to the DEX public chain after that. CET tokens that need to participate in token confusion can also be carried out through the privacy transaction of the Privacy public chain, and can eventually be returned to the DEX public chain. The three public chains are responsible for their respective duties, and they are interconnected through the cross-chain technology through the relay mechanism. In addition to ensuring their respective transaction processing speed and functional attributes, they can also jointly provide richer and safer functions, and synergistically constitute the CoinEx decentralized public chain ecosystem.
In addition, CoinEx Chain also supports any participant to issue new tokens on the chain and create new trading pairs for the issued tokens. CoinEx Chain guarantees the circulation of new tokens by establishing a trading pair between the new token and CET.

2.2 Component architecture

“ Tendermint Core and Cosmos SDK have improved the performance and operation capability of the blockchain. The SDK packaging reduces the consideration of non-related logic, hence reducing the development complexity.
CoinEx Chain is based on Tendermint Core and Cosmos SDK, both of which have brought a big boost to the development of CoinEx public chain performance. Cosmos-SDK will implement the application logic of the blockchain. Together with the Tendermint consensus engine, it implements the three-layer architecture of the CoinEx public chain: the application layer, the consensus layer, and the network layer.
Tendermint
Tendermint is based on the state machine replication technology and is suitable for blockchain ledger storage. It is a list of transactions making consensus with Byzantine fault tolerance, the transactions are executed in the same order, and eventually the same state is obtained. Tendermint can be used to build various distributed applications.
Cosmos SDK
Cosmos-SDK is a blockchain framework that supports the construction of multiple assets with a consensus mechanism of POS (Proof of Stake) or POA (Proof of Authority). The goal of the Cosmos SDK is to allow developers to easily build custom blockchains from 0, while enabling the interaction with other blockchains.
Cosmos-SDK is a blockchain framework that supports the construction of multiple assets with a consensus mechanism of POS (Proof of Stake) or POA (Proof of Authority). The goal of the Cosmos SDK is to allow developers to easily build custom blockchains from 0, while enabling the interaction with other blockchains. The blockchain development framework Cosmos SDK implements general functions such as account management, community governance, and staking in a modular form. Therefore, using the Cosmos SDK to build a public chain can simplify development procedures and facilitate operation. Tendermint is a fixed protocol in a partially synchronized environment, which can achieve throughput within a delay range of the network and each process itself. The CoinEx public chain is developed based on both, improving the performance and operability of the blockchain. The SDK packaging further reduces considerations of non-related logic and reduces the complexity of developers creating. The two components of Tendermint and Cosmos SDK are connected and interacted through the Application Blockchain Interface.

2.3 Project public chain planning

The development plan of the CoinEx public chain is to create a series of public chains with specific application directions, including:
  1. DEX public chain: solve the problems of lack of security and opacity that are widely criticized by centralized exchanges at present; aim to build a transparent, safe, and permission-free financial platform; restore the experience of central exchanges to the greatest extent;
  2. Smart public chain: a public chain that specifically supports smart contracts and provides a platform for building complex financial applications;
  3. Privacy public chain: mainly provides transaction amount, account balance, and information protection and the hiding of both parties to the transaction.
In order to achieve the performance of each specific application public chain, each public chain in the CoinEx public chain focuses on the development of a certain function. For example, in order to improve the transaction processing speed of the DEX public chain, the DEX public chain only supports the necessary functions and does not support smart contracts. To achieve the smart contract function support, cross-chain connection between the DEX public chain and the Smart public chain is required.

2.4 Operation analysis

“ The CoinEx platform publishes monthly ecosystem reports with high transparency; but the monthly reports are limited to contents about transactions and development, and lack progress in ecosystem and community construction, making them relatively simple.
2.4.1 Disclosure of ecosystem information
Operational risks have a direct impact on platform users. Whether platform operations are smooth and whether there is transparency are issues that platform users care about.
The CoinEx platform was established in 2017 and has around 3 years of development. It is also one of the platforms that has been developing for a long time in the exchange industry. It has obtained a digital currency trading license issued by the Estonian Financial Intelligence Unit (FIU), and the platform’s compliance is guaranteed to some degree.
The actual operation of the CoinEx platform will be displayed in the form of ecosystem monthly reports. The monthly report contains various types of content such as online currencies, new activities, plans for the next month, and ecosystem dynamics. It involves multiple business dimensions including the CoinEx exchange, CoinEx Public Chain, and CET token.

2.4.2 Roadmap
CoinEx Chain released its development roadmap for the four quarters of 2020 in January 2020. The roadmap shows that CoinEx Chain will undergo major updates on smart contracts and DEX hard fork upgrades. The project roadmap is basically planned on a monthly basis, with a clear plan and a clear direction of development.
CoinEx Public Chain 2020 Development Roadmap,Source: CoinEx; TokenInsight
In addition to the development route planned in the roadmap, CoinEx public chain also discloses its goals for next month in its monthly ecological report. The project’s main net was launched online in November 2019. According to TokenInsight’s review of the development of CoinEx public chain from January to April and the disclosure of the project’s ecosystem monthly report, the project’s plan about development of the smart contract Demo in February failed to be completed as planned; the project completed launching of the new version of the blockchain browser and the Asian Atlantis upgrade; the smart contract virtual machine development was planned to be completed in April, but the progress related to supporting cross-chain agreements was not disclosed yet.
Overall, the project’s development route planning is clear, and the project’s development schedule is consistent with the plan, but there are still some discrepancies. Operation and development information is disclosed every month, and information transparency is high.

3. Industry & Competitors

The earliest origin of the exchange layout in the public chain field began in early 2018 when Binance released an announcement to start the development of the Binance Public Chain officially. In June of the same year, Huobi announced at its brand upgrade conference that it will combine the technical capabilities of the Huobi technical team and the community developers to develop the Huobi public chain called “Huobi Chain”. In December of the same year, OK Group announced the launch of its self-developed public chain OKchain, dedicating to provide underlying technical support and services for startups stationed in B-Labs.
The successful launch of the public chain brings huge strategic significance to the exchange, which can not only improve the performance of the existing business of the exchange but also achieve further expansion of its influence. As one of the most important blockchain infrastructures, the public chain can benefit the exchanges behind it.
As a platform for developing public chain technology exchanges, CoinEx’s main competitors in the field of public chain development include Binance, Huobi, and OKEx. Although they are all exchange platforms for deploying public chains, the above four are different in terms of specific functions, economic models, and critical points of the public chain.

3.1 Development progress comparison

In 2019, Binance became the first exchange to launch a public chain among all digital asset exchanges, and its main product is Binance exchange (DEX). In April 2020, Binance announced the launch of a second smart contract chain, using Ethereum’s virtual machine, so that developers can build decentralized applications without affecting the performance and functionality of their original chain.
OKEx launched OKChain’s testnet in February 2020 and completed open source two months later. OKChain is designed as the basis of large-scale blockchain-driven business applications, with the characteristics of source code decentralization, point-to-point, irreversibility, and efficient autonomy.
Huobi released Huobi Chain for the first time in July 2019, the code is open source, and the testnet was released in February 2020. As a “regulator-friendly financial blockchain”, Huobi Chain focuses on providing compliance services for companies and financial institutions.
The CoinEx public chain officially completed the main online launch in November 2019 and completed the new block browser’s launch in March 2020. On April 3, 2020, CoinEx DEX uploaded the underlying code to Github to achieve open source. The CoinEx public chain is more inclined to build a full DEX ecosystem to achieve a one-stop solution for issuing, listing, storing, and trading. The long-term goal is to create a blockchain financial infrastructure.

3.2 Comparison of economic models

At present, the exchange is more inclined to use its existing platform currency as the native token of the public chain in the construction of public chain ecology. CoinEx’s CET, Binance’s BNB, and Huobi’s HT all fall into this category. OKEx is the only exchange that issues new tokens for its OKChain, which means OKT is the only ‘inflation token’ in the exchange’s public chain, while CET, HT, and BNB are all deflationary.

3.3 Decentralization of public chain

The initial number of CoinEx public chain verification nodes is 42, which is currently the most decentralized among all exchange public chains, and able to take both efficiency and decentralization into account; OKChain also currently has a relatively high degree of decentralization in the exchange public chain (21 verification nodes), its nodes have a high degree of autonomy; by contrast, Binance still firmly controls the operation of nodes and transactions; In terms of encourages cooperation between regulators and the private financial aspects, Huobi provides a lesser degree of decentralization. Huobi Chain uses a variant of the DPoS consensus algorithm to provide functions such as “supervision nodes”, allowing regulators to become validators.

4. Token Economy

CoinEx Token (CET) is a native token of the CoinEx ecosystem. It was issued in January 2018. Token holders can enjoy some user value-added services within the ecosystem. Currently, it is mainly used as a native token on the CoinEx Chain. As of 11 am on April 23, 2020, the current circulation of CET tokens in the market is 3,215,354,906.31, with a total of 5,842,177,609.53. CET tokens will not be further issued or inflated. Currently, daily repurchase and quarterly destruction are carried out. The repurchase destruction dynamics can now be tracked real-time on the CET repurchase system on the platform.

4.1 Token Distribution

The CET token used to be based on the ERC-20 token developed by Ethereum. Since the CoinEx Chain mainnet was launched in November 2019, some ERC-20 CET tokens have been mapped to the mainnet CET, and the rest of the CET will be mapped before November 10, 2020. CET holders need to deposit ERC-20 CET to the COinEX exchange, and the exchange will conduct the main network mapping.
At present, CET is mainly circulated in the form of mainnet tokens, and only a small portion of ERC-20 CET has not been mapped. The distribution of token holdings currently circulating on the mainnet can be seen in the figure below. At present, the number of tokens held by the top ten holders accounts for about 60.44% of all mainnet CET tokens.
Distribution of CET token holding addresses,Source: Etherscan; TokenInsight
The following figure shows the initial distribution of tokens after the mainnet mapping preset by CoinEx. From the initial distribution map of CET, it shows that, after mapping, a large portion of CET remains concentrated in the hands of the team (31%), and the actual number of CET circulating in the market only accounts for 49% of the total.

After the main net mapping, the 31% of the total CET (1.8 billion) held by the team will be gradually unlocked in the five years from 2020 to 2024, and 360 million CET will be unlocked each year. By 2024, the CET held by the team will be completely unlocked. From the current CET dynamics, the CET share held by some teams has been used for destruction purposes to achieve the purpose of CET austerity. If the frozen 1.8 billion CET held by the team are used for similar purposes, the development of CET and its platform can benefit from it.

4.2 Token economic model

4.2.1 Deflation mechanism
Since the CET token went online in January 2018, CoinEx has increased the circulation of CET through airdrops, transaction fee refunds, operation promotion, and team unlocking. As one of the existing platform coins with long development time, the deflation mechanism of CET token has undergone a series of changes with the development of the industry. In 2018, when the concept of coin-based mining prevailed, CET used transaction mining, stake mining, and pending order mining, which were cancelled in October, December and, April respectively of the following year.
The repurchase and destruction model currently used by CET was updated by CoinEx on April 11, 2020. The original CET quarterly repurchase and destruction policy of the platform will be adjusted to daily repurchase and quarterly destruction. After the implementation of the daily repurchase policy, CoinEx will take out 50% of the daily fee income for CET repurchase in the secondary market and implement quarterly destruction until the total remaining circulation is 3 billion (currently about 5.8 billion).
At the same time that CoinEx updated the repurchase and destruction plan on April 11, the platform also launched a page dedicated to displaying CET repurchase information, so that users can clearly understand the progress of CET repurchase and destruction.
As of April 23, 2020, the platform has destroyed 4,157,822,390.46 CET tokens, accounting for 41.6% of the initial total issuance. At the end of January 2019, it had destroyed 4 billion CETs (single destruction volume peak) at the end of this quarter. The number of CETs to be destroyed is 3,422,983.56.

4.2.2 Application scenarios
The current usage scenarios of CET are discounted platform transaction fees, VIP services, special activities rights and interests, CoinEx Chain internal circulation fuel, and use of external scenarios.
Deduction and discount of platform transaction fees
CoinEx platform users can use CET to deduct transaction fees when conducting transactions within the platform. At the same time, using CET to pay transaction fees can enjoy the exclusive preferential rates provided by the platform.

VIP service
Holding a certain number of CETs can make a user become a platform VIP user. Users can also use CET to purchase platform VIPs to obtain corresponding privileges such as discounted rates, accelerated withdrawals, and exclusive customers.
Special activity rights
CET holders can enjoy special rights and interests in platform marketing activities, such as participating in the airdrop of tokens on the platform or accelerating opportunities for high-quality projects.
CoinEx Chain built-in token
CET will serve as a native token of CoinEx Chain, circulate and serve as fuel in CoinEx Chain, and users can also use CET to invest or trade other digital assets. In addition, CET can also serve as transaction fees and function fees (issuing Token, creating new trading pairs, account activation), etc. in the platform, and users can also participate in the campaign of validators by staking CET tokens.
CET is currently used as a circulation token as well for CoinEx DEX to issue tokens, create orders, Bancor, address activation, set address aliases, and other application scenarios.
In general, the types of application scenarios of CET are not plenty enough. In order to better develop the internal ecosystem of the platform, it is necessary to design and develop more CET usage scenarios and incentive mechanisms to increase the retention rate of users while adding new users.
4.2.3 Token incentive
As the native token of the CoinEx public chain, CET will be used as a block incentive to increase community participation after the mainnet of the public chain launched. The 315 million CET held by the foundation in the total CET issuance will be used to incentivize initial verification nodes and Staking participants.

Transcription compiled by Theresa Boettger, Polkadot Ambassador:

Dieter Fishbein, Ecosystem Development Lead, Web3 Foundation

Dan: Hey everyone, thanks for joining us for the Polkadot Launch AMA. We have Dieter Fishbein (Head of Ecosystem Development, our business development team), Logan Saether (Technical Education), and Will Pankiewicz (Master of Validators) joining us today.
We had some great questions submitted in advance, and we’ll start by answering those and learning a bit about each of our guests. After we go through the pre-submitted questions, then we’ll open up the chat to live Q&A and the hosts will answer as many questions as they can.
We’ll start off with Dieter and ask him a set of some business-related questions.

Dieter could you introduce yourself, your background, and your role within the Polkadot ecosystem?

Dieter: I got my start in the space as a cryptography researcher at the University of Waterloo. This is where I first learned about Bitcoin and started following the space. I spent the next four years or so on the investment team for a large asset manager where I primarily focused on emerging markets. In 2017 I decided to take the plunge and join the space full-time. I worked at a small blockchain-focused VC fund and then joined the Polkadot team just over a year ago. My role at Polkadot is mainly focused on ensuring there is a vibrant community of projects building on our technology.

Q: Adoption of Polkadot of the important factors that all projects need to focus on to become more attractive to the industry. So, what is Polkadot's plan to gain more Adoption? [sic]

A (Dieter): Polkadot is fundamentally a developer-focused product so much of our adoption strategy is focused around making Polkadot an attractive product for developers. This has many elements. Right now the path for most developers to build on Polkadot is by creating a blockchain using the Substrate framework which they will later connect to Polkadot when parachains are enabled. This means that much of our adoption strategy comes down to making Substrate an attractive tool and framework. However, it’s not just enough to make building on Substrate attractive, we must also provide an incentive to these developers to actually connect their Substrate-based chain to Polkadot. Part of this incentive is the security that the Polkadot relay chain provides but another key incentive is becoming interoperable with a rich ecosystem of other projects that connect to Polkadot. This means that a key part of our adoption strategy is outreach focused. We go out there and try to convince the best projects in the space that building on our technology will provide them with significant value-add. This is not a purely technical argument. We provide significant support to projects building in our ecosystem through grants, technical support, incubatoaccelerator programs and other structured support programs such as the Substrate Builders Program (https://www.substrate.io/builders-program). I do think we really stand out in the significant, continued support that we provide to builders in our ecosystem. You can also take a look at the over 100 Grants that we’ve given from the Web3 Foundation: https://medium.com/web3foundation/web3-foundation-grants-program-reaches-100-projects-milestone-8fd2a775fd6b

Q: On moving forward through your roadmap, what are your most important next priorities? Does the Polkadot team have enough fundamentals (Funds, Community, etc.) to achieve those milestones?

A (Dieter): I would say the top priority by far is to ensure a smooth roll-out of key Polkadot features such as parachains, XCMP and other key parts of the protocol. Our recent Proof of Authority network launch was only just the beginning, it’s crucial that we carefully and successfully deploy features that allow builders to build meaningful technology. Second to that, we want to promote adoption by making more teams aware of Polkadot and how they can leverage it to build their product. Part of this comes down to the outreach that I discussed before but a major part of it is much more community-driven and many members of the team focus on this.
We are also blessed to have an awesome community to make this process easier 🙂

Q: Where can a list of Polkadot's application-specific chains can be found?

A (Dieter): The best list right now is http://www.polkaproject.com/. This is a community-led effort and the team behind it has done a terrific job. We’re also working on providing our own resource for this and we’ll share that with the community when it’s ready.

Q: Could you explain the differences and similarities between Kusama and Polkadot?

A (Dieter): Kusama is fundamentally a less robust, faster-moving version of Polkadot with less economic backing by validators. It is less robust since we will be deploying new technology to Kusama before Polkadot so it may break more frequently. It has less economic backing than Polkadot, so a network takeover is easier on Kusama than on Polkadot, lending itself more to use cases without the need for bank-like security.
In exchange for lower security and robustness, we expect the cost of a parachain lease to be lower on Kusama than Polkadot. Polkadot will always be 100% focused on security and robustness and I expect that applications that deal with high-value transactions such as those in the DeFi space will always want a Polkadot deployment, I think there will be a market for applications that are willing to trade cheap, high throughput for lower security and robustness such as those in the gaming, content distribution or social networking sectors. Check out - https://polkadot.network/kusama-polkadot-comparing-the-cousins/ for more detailed info!

Q: and for what reasons would a developer choose one over the other?

A (Dieter): Firstly, I see some earlier stage teams who are still iterating on their technology choosing to deploy to Kusama exclusively because of its lower-stakes, faster moving environment where it will be easier for them to iterate on their technology and build their user base. These will likely encompass the above sectors I identified earlier. To these teams, Polkadot becomes an eventual upgrade path for them if, and when, they are able to perfect their product, build a larger community of users and start to need the increased stability and security that Polkadot will provide.
Secondly, I suspect many teams who have their main deployment on Polkadot will also have an additional deployment on Kusama to allow them to test new features, either their tech or changes to the network, before these are deployed to Polkadot mainnet.

Logan Saether, Technical Education, Web3 Foundation

Q: Sweet, let's move over to Logan. Logan - could you introduce yourself, your background, and your role within the Polkadot ecosystem?

A (Logan): My initial involvement in the industry was as a smart contract engineer. During this time I worked on a few projects, including a reboot of the Ethereum Alarm Clock project originally by Piper Merriam. However, I had some frustrations at the time with the limitations of the EVM environment and began to look at other tools which could help me build the projects that I envisioned. This led to me looking at Substrate and completing a bounty for Web3 Foundation, after which I applied and joined the Technical Education team. My responsibilities at the Technical Education team include maintaining the Polkadot Wiki as a source of truth on the Polkadot ecosystem, creating example applications, writing technical documentation, giving talks and workshops, as well as helping initiatives such as the Thousand Validator Programme.

Q: The first technical question submitted for you was: "When will an official Polkadot mobile wallet appear?"

A (Logan): There is already an “official” wallet from Parity Technologies called the Parity Signer. Parity Signer allows you to keep your private keys on an air-gapped mobile device and to interactively sign messages using web interfaces such as Polkadot JS Apps. If you’re looking for something that is more of an interface to the blockchain as well as a wallet, you might be interested in PolkaWallet which is a community team that is building a full mobile interface for Polkadot.
For more information on Parity Signer check out the website: https://www.parity.io/signe

Q: Great thanks...our next question is: If someone already developed an application to run on Ethereum, but wants the interoperability that Polkadot will offer, are there any advantages to rebuilding with Substrate to run as a parachain on the Polkadot network instead of just keeping it on Ethereum and using the Ethereum bridge for use with Polkadot?

A (Logan): Yes, the advantage you would get from building on Substrate is more control over how your application will interact with the greater Polkadot ecosystem, as well as a larger design canvas for future iterations of your application.
Using an Ethereum bridge will probably have more cross chain latency than using a Polkadot parachain directly. The reason for this is due to the nature of Ethereum’s separate consensus protocol from Polkadot. For parachains, messages can be sent to be included in the next block with guarantees that they will be delivered. On bridged chains, your application will need to go through more routes in order to execute on the desired destination. It must first route from your application on Ethereum to the Ethereum bridge parachain, and afterward dispatch the XCMP message from the Polkadot side of the parachain. In other words, an application on Ethereum would first need to cross the bridge then send a message, while an application as a parachain would only need to send the message without needing to route across an external bridge.

Q: DOT transfers won't go live until Web3 removes the Sudo module and token holders approve the proposal to unlock them. But when will staking rewards start to be distributed? Will it have to after token transfers unlock? Or will accounts be able to accumulate rewards (still locked) once the network transitions to NPoS?

A (Logan): Staking rewards will be distributed starting with the transition to NPoS. Transfers will still be locked during the beginning of this phase, but reward payments are technically different from the normal transfer mechanism. You can read more about the launch process and steps at http://polkadot.network/launch-roadmap

Q: Next question is: I'm interested in how Cumulus/parachain development is going. ETA for when we will see the first parachain registered working on Kusama or some other public testnet like Westend maybe?

A (Logan): Parachains and Cumulus is a current high priority development objective of the Parity team. There have already been PoC parachains running with Cumulus on local testnets for months. The current work now is making the availability and validity subprotocols production ready in the Polkadot client. The best way to stay up to date would be to follow the project boards on GitHub that have delineated all of the tasks that should be done. Ideally, we can start seeing parachains on Westend soon with the first real parachains being deployed on Kusama thereafter.
The projects board can be viewed here: https://github.com/paritytech/polkadot/projects
Dan: Also...check out Basti's tweet from yesterday on the Cumulus topic: https://twitter.com/bkchstatus/1270479898696695808?s=20

Q: In what ways does Polkadot support smart contracts?

A (Logan): The philosophy behind the Polkadot Relay Chain is to be as minimal as possible, but allow arbitrary logic at the edges in the parachains. For this reason, Polkadot does not support smart contracts natively on the Relay Chain. However, it will support smart contracts on parachains. There are already a couple major initiatives out there. One initiative is to allow EVM contracts to be deployed on parachains, this includes the Substrate EVM module, Parity’s Frontier, and projects such as Moonbeam. Another initiative is to create a completely new smart contract stack that is native to Substrate. This includes the Substrate Contracts pallet, and the ink! DSL for writing smart contracts.

Will Pankiewicz, Master of Validators, Parity Technologies


Q: (Dan) Thanks for all the answers. Now we’ll start going through some staking questions with Will related to validating and nominating on Polkadot. Will - could you introduce yourself, your background, and your role within the Polkadot ecosystem?

A (Will): Sure thing. Like many others, Bitcoin drew me in back in 2013, but it wasn't until Ethereum came that I took the deep dive into working in the space full time. It was the financial infrastructure aspects of cryptocurrencies I was initially interested in, and first worked on dexes, algorithmic trading, and crypto funds. I really liked the idea of "Generalized Mining" that CoinFund came up with, and started to explore the whacky ways the crypto funds and others can both support ecosystems and be self-sustaining at the same time. This drew me to a lot of interesting experiments in what later became DeFi, as well as running validators on Proof of Stake networks. My role in the Polkadot ecosystem as “Master of Validators” is ensuring the needs of our validator community get met.

Q: Cool thanks. Our first community question was "Is it still more profitable to nominate the validators with lesser stake?"

A (Will): It depends on their commission, but generally yes it is more profitable to nominate validators with lesser stake. When validators have lesser stake, when you nominate them this makes your nomination stake a higher percentage of total stake. This means when rewards get distributed, it will be split more favorably toward you, as rewards are split by total stake percentage. Our entire rewards scheme is that every era (6 hours in Kusama, 24 hours in Polkadot), a certain amount of rewards get distributed, where that amount of rewards is dependent on the total amount of tokens staked for the entire network (50% of all tokens staked is currently optimal). These rewards from the end of an era get distributed roughly equally to all validators active in the validator set. The reward given to each validator is then split between the validators and all their nominators, determined by the total stake that each entity contributes. So if you contribute to a higher percentage of the total stake, you will earn more rewards.

Q: What does priority ranking under nominator addresses mean? For example, what does it mean that nominator A has priority 1 and nominator B has priority 6?

A (Will): Priority ranking is just the index of the nomination that gets stored on chain. It has no effect on how stake gets distributed in Phragmen or how rewards get calculated. This is only the order that the nominator chose their validators. The way that stake from a nominator gets distributed from a nominator to validators is via Phragmen, which is an algorithm that will optimally put stake behind validators so that distribution is roughly equal to those that will get in the validator set. It will try to maximize the total amount at stake in the network and maximize the stake behind minimally staked validators.

Q: On Polkadot.js, what does it mean when there are nodes waiting on Polkadot?

**A (Will):**In Polkadot there is a fixed validator set size that is determined by governance. The way validators get in the active set is by having the highest amount of total stake relative to other validators. So if the validator set size is 100, the top 100 validators by total stake will be in the validator set. Those not active in the validator set will be considered “waiting”.

Q: Another question...Is it necessary to become a waiting validator node right now?

A (Will): It's not necessary, but highly encouraged if you actively want to validate on Polkadot. The longer you are in the waiting tab, the longer you get exposure to nominators that may nominate you.

Q: Will current validators for Kusama also validate for Polkadot? How strongly should I consider their history (with Kusama) when looking to nominate a good validator for DOTs?

A (Will): A lot of Kusama validators will also be validators for Polkadot, as KSM was initially distributed to DOT holders. The early Kusama Validators will also likely be the first Polkadot validators. Being a Kusama validator should be a strong indicator for who to nominate on Polkadot, as the chaos that has ensued with Kusama has allowed validators to battle test their infrastructure. Kusama validators by now are very familiar with tooling, block explorers, terminology, common errors, log formats, upgrades, backups, and other aspects of node operation. This gives them an edge against Polkadot validators that may be new to the ecosystem. You should strongly consider well known Kusama validators when making your choices as a nominator on Polkadot.

Q: Can you go into more details about the process for becoming a DOT validator? Is it similar as the KSM 1000 validators program?

A (Will): The Process for becoming a DOT validators is first to have DOTs. You cannot be a validator without DOTs, as DOTs are used to pay transaction fees, and the minimum amount of DOTs you need is enough to create a validate transaction. After obtaining enough DOTs, you will need to set up your validator infrastructure. Ideally you should have a validator node with specs that match what we call standard hardware, as well as one or more sentry nodes to help isolate the validator node from attacks. After the infrastructure is up and running, you should have your Polkadot accounts set up right with a stash bonded to a controller account, and then submit a validate transaction, which will tell the network your nodes are ready to be a part of the network. You should then try and build a community around your validator to let others know you are trustworthy so that they will nominate you. The 1000 validators programme for Kusama is a programme that gives a certain amount of nominations from the Web3 Foundation and Parity to help bootstrap a community and reputation for validators. There may eventually be a similar type of programme for Polkadot as well.
Dan: Thanks a lot for all the answers, Will. That’s the end of the pre-submitted questions and now we’ll open the chat up to live Q&A, and our three team members will get through as many of your questions as possible.
We will take questions related to business development, technology, validating, and staking. For those wondering about DOT:
DOT tokens do not exist yet. Allocations of Polkadot's native DOT token are technically and legally non-transferable. Hence any publicized sale of DOTs is unsanctioned by Web3 Foundation and possibly fraudulent. Any official public sale of DOTs will be announced on the Web3 Foundation website. Polkadot’s launch process started in May and full network decentralization later this year, holders of DOT allocations will determine issuance and transferability. For those who participated in previous DOT sales, you can learn how to claim your DOTs here (https://wiki.polkadot.network/docs/en/claims).


Telegram Community Follow-up Questions Addressed Below


Q: Polkadot looks good but it confuses me that there are so many other Blockchain projects. What should I pay attention in Polkadot to give it the importance it deserves? What are your planning to achieve with your project?

A (Will): Personally, what I think differentiates it is the governance process. Coordinating forkless upgrades and social coordination helps stand it apart.
A (Dieter): The wiki is awesome - https://wiki.polkadot.network/

Q: Over 10,000 ETH paid as a transaction fee , what if this happens on Polkadot? Is it possible we can go through governance to return it to the owner?

A: Anything is possible with governance including transaction reversals, if a network quorum is reached on a topic.
A (Logan): Polkadot transaction fees work differently than the fees on Ethereum so it's a bit more difficult to shoot yourself in the foot as the whale who sent this unfortunate transaction. See here for details on fees: https://w3f-research.readthedocs.io/en/latest/polkadot/Token%20Economics.html?highlight=transaction%20fees#relay-chain-transaction-fees-and-per-block-transaction-limits
However, there is a tip that the user can input themselves which they could accidentally set to a large amount. In this cases, yes, they could proposition governance to reduce the amount that was paid in the tip.

Q: What is the minimum ideal amount of DOT and KSM to have if you want to become a validator and how much technical knowledge do you need aside from following the docs?

A (Will): It depends on what the other validators in the ecosystem are staking as well as the validator set size. You just need to be in the top staking amount of the validator set size. So if its 100 validators, you need to be in the top 100 validators by stake.

Q: Will Web3 nominate validators? If yes, which criteria to be elected?

A (Will): Web 3 Foundation is running programs like the 1000 validators programme for Kusama. There's a possibility this will continue on for Polkadot as well after transfers are enabled. https://thousand-validators.kusama.network/#/
You will need to be an active validator to earn rewards. Only those active in the validator set earn rewards. I would recommend checking out parts of the wiki: https://wiki.polkadot.network/docs/en/maintain-guides-validator-payout

Q: Is it possible to implement hastables or dag with substrate?

A (Logan): Yes.

Q: Polkadot project looks very futuristic! But, could you tell us the main role of DOT Tokens in the Polkadot Ecosystem?

A (Dan): That's a good question. The short answer is Staking, Governance, Bonding. More here: http://polkadot.network/dot-token

Q: How did you manage to prove that the consensus protocol is safe and unbreakable mathematically?

A (Dieter): We have a research teams of over a dozen scientists with PhDs and post-docs in cryptography and distributed computing who do thorough theoretical analyses on all the protocols used in Polkadot

A (Will): https://polkadot.network/launch-roadmap/
This is the launch roadmap. Ideally adding parachains and xcmp towards the end of the year

Q: How Do you stay active in terms of marketing developments during this PANDEMIC? Because I'm sure you're very excited to promote more after this settles down.

A (Dan): The main impact of covid was the impact on in-person events. We have been very active on Crowdcast for webinars since 2019, so it was quite the smooth transition to all-online events. You can see our 40+ past event recordings and follow us on Crowdcast here: https://www.crowdcast.io/polkadot. If you're interested in following our emails for updates (including online events), subscribe here: https://info.polkadot.network/subscribe

Q: Hi, who do you think is your biggest competitor in the space?

A (Dan): Polkadot is a metaprotocol that hasn't been seen in the industry up until this point. We hope to elevate the industry by providing interoperability between all major public networks as well as private blockchains.

Q: Is Polkadot a friend or competitor of Ethereum?

A: Polkadot aims to elevate the whole blockchain space with serious advancements in interoperability, governance and beyond :)

Q: When will there be hardware wallet support?

A (Will): Parity Signer works well for now. Other hardware wallets will be added pretty soon

Q: What are the attractive feature of DOT project that can attract any new users ?

A: https://polkadot.network/what-is-polkadot-a-brief-introduction/
A (Will): Buidling parachains with cross chain messaging + bridges to other chains I think will be a very appealing feature for developers

Q: According to you how much time will it take for Polkadot to get into mainstream adoption and execute all the plans set for this project?

A: We are solving many problems that have held back the blockchain industry up until now. Here is a summary in basic terms:

Q: When will bitpie or imtoken support DOT?

A: We are working on integrations on all the biggest and best wallet providers. ;)

Q: What event/call can we track to catch a switch to nPOS? Is it only force_new_era call? Thanks.

A (Will): If you're on riot, useful channels to follow for updates like this are #polkabot:matrix.org and #polkadot-announcements:matrix.parity.io
A (Logan): Yes this is the trigger for initiating the switch to NPoS. You can also poll the ForceEra storage for when it changes to ForceNew.

Q: What strategy will the Polkadot Team use to make new users trust its platform and be part of it?

A (Will): Pushing bleeding edge cryptography from web 3 foundation research
A (Dan): https://t.me/PolkadotOfficial/43378

Q: What technology stands behind and What are its advantages?

A (Dieter): Check out https://polkadot.network/technology/ for more info on our tech stack!

Q: What problems do you see occurring in the blockchain industry nowadays and how does your project aims to solve these problems?

A (Will): Governance I see as a huge problem. For example upgrading Bitcoin and making decisions for changing things is a very challenging process. We have robust systems of on-chain governance to help solve these coordination problems

Q: How involved are the Polkadot partners? Are they helping with the development?

A (Dieter): There are a variety of groups building in the Polkadot ecosystem. Check out http://www.polkaproject.com/ for a great list.

Q: Can you explain the role of the treasury in Polkadot?

A (Will): The treasury is for projects or people that want to build things, but don't want to go through the formal legal process of raising funds from VCs or grants or what have you. You can get paid by the community to build projects for the community.
A: There’s a whole section on the wiki about the treasury and how it functions here https://wiki.polkadot.network/docs/en/mirror-learn-treasury#docsNav

Q: Any plan to introduce Polkadot on Asia, or rising market on Asia?

**A (Will):**We're globally focused

Q: What kind of impact do you expect from the Council? Although it would be elected by token holders, what kind of people you wish to see there?

A (Will): Community focused individuals like u/jam10o that want to see cool things get built and cool communities form

If you have further questions, please ask in the official Polkadot Telegram channel.

Chromia - Blockchain of Blockchains That Has Staged To Revolutionize Decentralized Application Development

Blockchain has taken the world by storm. The tech may have been envisioned to power decentralized finance in Bitcoin, it's potential and use case had far exceeded such identity.
It has opened the possibility to develop trust and openness in a way that has never been expressed before.
However, like any new development, blockchain has many challenges that need to be addressed.
Firstly, existing protocols that power the initial set of blockchains are too slow to garner advanced real-world usage.
Their architectural build also implies they are unable to scale accordingly to meet application and usage demand.
Blockchains are renowned for their strong security and immutability, nonetheless, these factors rely solely on the type of protocol or consensus adopted, and in many cases, the consensus of a particular blockchain may fail to establish a secured environment that could be relied upon under factual circumstances.
On the developer end, developing and building blockchain applications is a nightmare many wanted to escape because most integrated blockchain programming languages are new with an unestablished root. This means programmers have to learn a new language from basics before they can start building on a blockchain network.
The hardest part is that almost each of every type and brand of blockchain has its unique programming language which as a result contributes to non-interoperability that led to a status quo of blockchains being called an "island of self-isolation".
An obvious solution to most of the aforementioned downsides is to start restructuring how blockchains are made by design and code.
The good news is that a blockchain project with a new root has already achieved the feat of addressing most of these problems by building a relational blockchain system governed by a management system termed "Postchain".
I am talking about Chromia blockchain network built by the ChromaWay development team.
Chromia
Chromia is a public blockchain with a relational database system build and design. What this means is that data can be structured and defined in any way by the builder of the system. This flexibility of data management allows for different usage scenarios.
This is a sweet pot for developers but what is more interesting is the ability to code and deploy applications in a seamless manner.
Chroma uses Postchain to oversee the operation of its blockchain network in conjunction with a flexible and easy-to-code programming language called RELL (Relational Language).
Great protocol design? Thumb up! Nice programming language... Interesting! But what about other challenges mentioned in the opening part of the post?
Hell yeah! A blockchain system cannot be duly considered if it can't scale and operate at a good speed.
Chromia takes this factor to heart and ensures its network is able to process transactions at a block rate of 2 seconds, which is more than enough to support most applications and commercial usage.
Blockchain Of Blockchains: Chromia Modular Configuration
One method spam is avoided on blockchain networks is through integrated fee structure, most times, this is charged directly from users. However, Chromia thinks this idea should be rewritten by instead charging Dapps directly for the operation they perform.
Consequently, and since most application usage differs from one type to another. This and many other implementations led to a modular blockchain design where each Dapp can reside on its own chain, dictate its own rule and usage and intended fee structure.
The Dapps in this case acts like side chains that are attached to the governing Chromia infrastructure. Each Dapp or side chain is independent but benefits from the security and laid facilities of the network.
Chromia adopted PBFT consensus to ensure consensus can be achieved under certain rules even if some node in the network cannot be relied upon at a time, thus, eliminating incidents such as 'one point of failure'.
An Infrastructure For A Wide Range Of Usage Scenario
Chromia launched its main net in Dec 2019, and moved from an experimental position to prove their dedication towards achieving their vision not just on paper but as a practical and working process.
Ever since their main net launch. The chain has seen different types of apps deploy on its network.
The network relational design also means Dapps with huge computational demand can work efficiently and seamlessly with any cause to worry.
Let's look at some of these Dapps.
Chromunity
A decentralized social media platform that leverages the advantage of the relational computational build of Chromia to bring about fantastic social and community user experience.
The advantages of Chromunity as a decentralized social platform is how users can control their data and interactions, vote for representatives that implement the will and voice of the community.
Chromunity features a Reddit-like design and interface with the ability to post short/long meaningful content to a wide range of community categories or specific ones.
These screenshots give a sneak peek into how the interactive user interface looks like.
Green Asset Wallet
This is the first enterprise Dapp to launch on the Chromia chain after its main net release.
Using the quote of how the project defines itself.
"Green Assets Wallet is the world’s first blockchain-based platform for easy validation and impact reporting of green bonds".
The product has many features that are designed to suit investor's needs. From real-time collaboration to ensuring optimum trust and transparency to security. The Dapp is ideal for green bonds operations that look to make issuer and investors' lives an easier one.
Investors have direct access to trusted green bond information, metrics, and data.
Green asset wallet at allows investors to make new investment discoveries through search criteria, compare, benchmark, and follow up on investment opportunities".
Issuers are able to operate with an independent, cost-efficient, and structured system, and provide investors with impact investment opportunities and report on achievements.
Mines Of Dalarnia
Is "an action-adventure platform-mining game where the player controls a character and guides them through various blocks of earth, to discover and collect minerals of multiple rarities. Includes a blockchain based real-estate market".
Chromia transaction speed and computational efficiency make it an ideal platform to build decentralized or blockchain games of different kinds.
Play Mines Of Dalarnia
Conclusion
Chromia combines many groundbreaking features that purport it as a new generation blockchain and set it out among the crowd.
It's easy to code programming language, Postchain consortium, relational database system express qualities that fit different needs of decentralized applications and their operations. All of which state the chain strength and confidence of usage.
Under the governance of ChromaWay - an organization of tech experts and geeks. Chromia is expected to continue on an upward positive momentum.
Learn more about the project from it's official website
Their Telegram group chat is a good place to start interacting with the community.
Chromia has a Twitter presence and their Whitepaper is a good reference and tool to have a good overview of the project mission and vision at large.

Upcoming Major Riecoin 0.20 Upgrade

Upcoming Major Riecoin 0.20 Upgrade
A new major Riecoin upgrade is planned, and includes a hard fork. Below is a summary of the changes so far and the hard fork improvements. More details can be found on BitcoinTalk. Feel free to ask Pttn there or on Discord if you have questions regarding the update.
The first step of this upgrade was to update the base code to Bitcoin’s 0.20, which is done. You can find the experimental code at the Github repository. Experimental binaries can also be downloaded here. Despite their prerelease status, they should work fine, though please backup your wallets if you plan to use 0.20, just in case.
Pool operators and other advanced Riecoin users should start looking into the changes and update their software accordingly, as well as closely follow the Riecoin Core development.
Here is a list of notable changes from 0.16.3.1.
The next step will be the hard fork, in order to improve Riecoin in multiple ways. Here is the list of planned changes.
Once the development is advanced enough, a date will be chosen for the hard fork. Testnet will be hardforked first to ensure the well functioning of the implementation. Stay tuned!
