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.

Eth 2.0 vs Polkadot and other musings by a fundamental investor

Spent about two hours on this post and I decided it would help the community if I made it more visible. Comment was made as a response to this
I’m trying to avoid falling into a maximalist mindset over time. This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
Can someone help me see the downsides of diversifying into DOTs?
I know Polkadot is more centralized, VC backed, and generally against our ethos here. On chain governance might introduce some unknown risks. What else am I missing?
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
Response:
What else am I missing?
The upsides.
Most of the guys responding to you here are full Eth maxis who drank the Parity is bad koolaid. They are married to their investment and basically emotional / tribal in an area where you should have a cool head. Sure, you might get more upvotes on Reddit if you do and say what the crowd wants, but do you want upvotes and fleeting validation or do you want returns on your investment? Do you want to be these guys or do you want to be the shareholder making bank off of those guys?
Disclaimer: I'm both an Eth whale and a Dot whale, and have been in crypto for close to a decade now. I originally bought ether sub $10 after researching it for at least a thousand hours. Rode to $1500 and down to $60. Iron hands - my intent has always been to reconsider my Eth position after proof of stake is out. I invested in the 2017 Dot public sale with the plan of flipping profits back to Eth but keeping Dots looks like the right short and long term play now. I am not a trader, I just take a deep tech dive every couple of years and invest in fundamentals.
Now as for your concerns:
I know Polkadot is more centralized
The sad truth is that the market doesn't really care about this. At all. There is no real statistic to show at what point a coin is "decentralized" or "too centralized". For example, bitcoin has been completely taken over by Chinese mining farms for about five years now. Last I checked, they control above 85% of the hashing power, they just spread it among different mining pools to make it look decentralized. They have had the ability to fake or block transactions for all this time but it has never been in their best interest to do so: messing with bitcoin in that way would crash its price, therefore their bitcoin holdings, their mining equipment, and their company stock (some of them worth billions) would evaporate. So they won't do it due to economics, but not because they can't.
That is the major point I want to get across; originally Bitcoin couldn't be messed with because it was decentralized, but now Bitcoin is centralized but it's still not messed with due to economics. It is basically ChinaCoin at this point, but the market doesn't care, and it still enjoys over 50% of the total crypto market cap.
So how does this relate to Polkadot? Well fortunately most chains - Ethereum included - are working towards proof of stake. This is obviously better for the environment, but it also has a massive benefit for token holders. If a hostile party wanted to take over a proof of stake chain they'd have to buy up a massive share of the network. The moment they force through a malicious transaction a proof of stake blockchain has the option to fork them off. It would be messy for a few days, but by the end of the week the hostile party would have a large amount of now worthless tokens, and the proof of stake community would have moved on to a version of the blockchain where the hostile party's tokens have been slashed to zero. So not only does the market not care about centralization (Bitcoin example), but proof of stake makes token holders even safer.
That being said, Polkadot's "centralization" is not that far off to Ethereum. The Web3 foundation kept 30% of the Dots while the Ethereum Foundation kept 17%. There are whales in Polkadot but Ethereum has them too - 40% of all genesis Ether went to 100 wallets, and many suspect that the original Ethereum ICO was sybiled to make it look more popular and decentralized than it really was. But you don't really care about that do you? Neither do I. Whales are a fact of life.
VC backed
VCs are part of the crypto game now. There is no way to get rid of them, and there is no real reason why you should want to get rid of them. They put their capital at risk (same as you and me) and seek returns on their investment (same as you and me). They are both in Polkadot and Ethereum, and have been for years now. I have no issue with them as long as they don't play around with insider information, but that is another topic. To be honest, I would be worried if VCs did not endorse chains I'm researching, but maybe that's because my investing style isn't chasing hype and buying SUSHI style tokens from anonymous (at the time) developers. That's just playing hot potato. But hey, some people are good at that.
As to the amount of wallets that participated in the Polkadot ICO: a little known fact is that more individual wallets participated in Polkadot's ICO than Ethereum's, even though Polkadot never marketed their ICO rounds due to regulatory reasons.
generally against our ethos here
Kool aid.
Some guy that works(ed?) at Parity (who employs what, 200+ people?) correctly said that Ethereum is losing its tech lead and that offended the Ethereum hivemind. Oh no. So controversial. I'm so personally hurt by that.
Some guy that has been working for free on Ethereum basically forever correctly said that Polkadot is taking the blockchain tech crown. Do we A) Reflect on why he said that? or B) Rally the mob to chase him off?
"I did not quit social media, I quit Ethereum. I did not go dark, I just left the community. I am no longer coordinating hard forks, building testnets, or contributing otherwise. I did not work on Polkadot, I never did, I worked on Ethereum. I did not hate Ethereum, I loved it."
Also Parity locked their funds (and about 500+ other wallets not owned by them) and proposed a solution to recover them. When the community voted no they backed off and did not fork the chain, even if they had the influence to do so. For some reason this subreddit hates them for that, even if Parity did the 100% moral thing to do. Remember, 500+ other teams or people had their funds locked, so Parity was morally bound to try its best to recover them.
Its just lame drama to be honest. Nothing to do with ethos, everything to do with emotional tribalism.
Now for the missing upsides (I'll also respond to random fragments scattered in the thread):
This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
A good quick intro to Eth's tech vs Polkadot's tech can be found on this thread, especially this reply. That thread is basically mandatory reading if you care about your investment.
Eth 2.0's features will not really kick in for end users until about 2023. That means every dapp (except DeFI, where the fees make sense due to returns and is leading the fee market) who built on Eth's layer 1 are dead for three years. Remember the trading card games... Gods Unchained? How many players do you think are going to buy and sell cards when the transaction fee is worth more than the cards? All that development is now practically worthless until it can migrate to its own shard. This story repeats for hundreds of other dapp teams who's projects are now priced out for three years. So now they either have to migrate to a one of the many unpopulated L2 options (which have their own list of problems and risks, but that's another topic) or they look for another platform, preferably one interoperable with Ethereum. Hence Polkadot's massive growth in developer activity. If you check out https://polkaproject.com/ you'll see 205 projects listed at the time of this post. About a week ago they had 202 listed. That means about one team migrated from another tech stack to build on Polkadot every two days, and trust me, many more will come in when parachains are finally activated, and it will be a complete no brainer when Polkadot 2.0 is released.
Another huge upside for Polkadot is the Initial Parachain Offerings. Polkadot's version of ICOs. The biggest difference is that you can vote for parachains using your Dots to bind them to the relay chain, and you get some of the parachain's tokens in exchange. After a certain amount of time you get your Dots back. The tokenomics here are impressive: Dots are locked (reduced supply) instead of sold (sell pressure) and you still earn your staking rewards. There's no risk of scammers running away with your Ether and the governance mechanism allows for the community to defund incompetent devs who did not deliver what was promised.
Wouldn’t an ETH shard on Polkadot gain a bunch of scaling benefits that we won’t see natively for a couple years?
Yes. That is correct. Both Edgeware and Moonbeam are EVM compatible. And if the original dapp teams don't migrate their projects someone else will fork them, exactly like SUSHI did to Uniswap, and how Acala is doing to MakerDao.
Although realistically Ethereum has a 5 yr headstart and devs haven't slowed down at all
Ethereum had a five year head start but it turns out that Polkadot has a three year tech lead.
Just because it's "EVM Compatible" doesn't mean you can just plug Ethereum into Polkadot or vica versa, it just means they both understand Ethereum bytecode and you can potentially copy/paste contracts from Ethereum to Polkadot, but you'd still need to add a "bridge" between the 2 chains, so it adds additional complexity and extra steps compared to using any of the existing L2 scaling solutions
That only applies of you are thinking from an Eth maximalist perspective. But if you think from Polkadot's side, why would you need to use the bridge back to Ethereum at all? Everything will be seamless, cheaper, and quicker once the ecosystem starts to flourish.
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
They are competitors. Both have their strategies, and both have their strengths (tech vs time on the market) but they are clearly competing in my eyes. Which is a good thing, Apple and Samsung competing in the cell phone market just leads to more innovation for consumers. You can still invest in both if you like.
Edit - link to post and the rest of the conversation: https://www.reddit.com/ethfinance/comments/iooew6/daily_general_discussion_september_8_2020/g4h5yyq/
Edit 2 - one day later PolkaProject count is 210. Devs are getting the hint :)

Is Paxful against responsible disclosure of vulnerabilities or is this all just a mistake? $10-$200 free BTC if we can resolve this

TLDR; I discovered and responsibly disclosed multiple bugs/vulnerabilities with significant impact on Paxful's marketplace, weeks later Paxful froze my account thinking I was maliciously making use of part of the very vulnerability I reported. I was testing whether had been fully patched as it posed risks to my operations as a vendor as well as Paxful's marketplace as a whole if it were publicly disclosed and abused by malicious actors. I would be happy to consider signing the NDA related to this vulnerability if we can resolve this in a timely manner. Things ended in my vendor account being bannéd nearly 2 weeks ago as the support and security team assumed API testing activity was spam despite my prior in-depth communications with them. They cited multiple warnings August 6-18 which, as cited below are not legitimate in nature and likely due to a break down in communications and/or failure to investigate the nature of my activity. I suspect some of this may be related to a language barrier as I and other vendors frequently receive messages in broken english containing incorrect or irrelevant information.
Please consider posting a comment regarding your experience with Paxful's bug bounty program or support team.
I am offering $10 in BTC to each Paxful ID verified user who comments on this post with a relevant comment if my Paxful account's ban is lifted. Moderators are excluded from this to avoid conflicts of interest. Additional restrictions:
Alternatively, if this post does not receive atleast 20 comments from ID verified users, I am offering $200 in BTC to anyone who can put me in touch with someone at Paxful who can actually resolve this. Payout will be made only if my vendor account ban is lifted.
5/17/20 — I reported vulnerability #1 to [[email protected]](mailto:[email protected])
07/06/20 — I reported vulnerability #2 to [[email protected]](mailto:[email protected]) "Trade transcripts can be made unretrievable, when abused by users moderators might be unable to review disputes" to [[email protected]](mailto:[email protected]) . Some of the testing involved posting arbitrary strings such as “aa.co”, “bbco”, etc. repeatedly to old cancelled trades. This is not spam, however it’s been wrongly assumed to be spam.
08/05/20 — Despite my clearly positive intentions, I was advised by a Paxful dev ops engineer to not attempt to mitigate the risk of coin lockers, scammers and extortion through the use of automated scripted messaging in trade chats as it could cause problems for Paxful staff. I was asked to strictly rely on moderators for resolving such issues (despite the historical lack of recourse against scams). I immediately ceased such activity and made it clear I was prepared to comply with this request and was previously unaware that this might cause problems for staff.
08/06/20 — No further use of scripted messaging to get rid of coin lockers, I opted to strictly rely on moderators for such issues. I performed tests via Paxful’s API related to the bug bounty report on 07/06/20 using specific API endpoints on trades where it would not hinder any transaction or where staff might need to be involved.
Criteria used for selected trades to use for vulnerability testing:
Ideally I would have used a test account or testnet like most exchanges offer but I was specifically told not to and prior to 08/05/20 there were no concerns about my usage of Paxful's API.
08/08-10/20 — (Request # 221122 ) My vendor account was frózen, I tweeted at raypaxful and it was unfrózen. I was told by support (request # 221122) that my API testing was flagged by Paxful’s system as spam. Support issued an apology and placed a note on my account that I may be performing such tests going forward and they valued my bug bounty reports.
08/12/20 — I was wrongly accused again of spamming the trade chat despite my continued compliance with the request from [[email protected]](mailto:[email protected]) on 08/05/20. Two trades were cited:GYokxnZdbmx — blatantly obvious API testing involving posting repeated strings such as “aa.co”
6Jm586J6Mox — trade from 04/21/20, why are you warning me about a trade from 4 months ago when it wasn’t indicated that Paxful had an issue with scripted message being use to deal with malicious actors when moderators are nowhere in sight? After all these months, why didn’t you take any action against the malicious user here? This doesn’t require contacting any gift card company, you can clearly see this user provided a cropped picture of a gift card making it unredeemable yet they locked my coins for days. The reason you’re aware of activity like this being a risk to the marketplace is a direct result of the bug bounty report I filed on on 07/06/20 for which I was never paid despite being promised a "reward". Who in their right mind is going to file a bug bounty report and then proceed to abuse that bug? A little more investigation and logical reasoning is needed here.
08/18/20 (Request # 170377) I was accused yet again of spamming the trade chat despite my continued compliance with the request from [[email protected]](mailto:[email protected]) on 08/05/20. I responded to this reminding support that I had continued to comply with this request and that “warning” me of something I’ve been in compliance with ever since I was aware of the issue is extremely disingenuous.
08/19/20 (Request # 170377), BitcoinBell’s response:*“Spamming and account notation: Like I said, I've communicated with [Paxful dev ops engineer name redacted] multiple times regarding excessive scripted messaging being used to ward off scammers, the behavior won't continue.”*Scripted messaging posted via API to deal with scammers had not taken place ever since the concern was first brought to my attention on 08/05/20. Paxful support appears to have been under the impression that this was not the case and proceeded to “warn me” again as if I was refusing to comply with their prior request. It would appear that they did not realize my activity was bug bounty related testing using old cancelled trades as my only authorized means of carrying out such tests without being disruptive to transactions.
“Had I known this caused problems for Paxful's team I wouldn't have done it but there was no mention in Paxful's API documentation that such activity could cause problems for Paxful's team. Most websites have proper rate limiting in place to deal with excessive posting of the same message so they don't have to waste their time policing what messages are being posted. Again, I'm not arguing for continuing this behavior as it's now been made clear it causes problems for Paxful's team but I hope you can see nothing in Paxful's API documentation clearly prohibits such use and that it was being used in good faith to ward off bad actors. In a marketplace filled with malicious actors, I don't appreciate being "warned" as if I did something malicious here when there was no indication of it being a problem, until recently.” (and have been in compliance with the request since first alerted on 08/05/20)”
08/21/20 I was offered a bug bounty payout for the vulnerabilities/bugs reported on 07/06/20 and 05/17/20. The amount was around 5-12% of the national average for bug bounty payouts. I was asked to sign a lengthy NDA which I had to forward to my attorney for review.
08/26/20 I made a counteroffer to the proposed bug bounty payments around and below the national average for bug bounty payouts.
08/26/20 I reported a new bug to [[email protected]](mailto:[email protected]) that could lead to users visiting malicious sites from Paxful's trade chat without warning.
08/27/20 8:01 AM UTC I reported a new bug to [[email protected]](mailto:[email protected]) that significantly impacted vendors in countless payment methods which since been patched:"Regex intended to block external contact info also blocks all gift card numbers that contain 6 sequential digits, huge potential burden on vendors, confusion for buyers"
08/27/20 8:30 AM UTC I received an e-mail that my vendor account had been bannéd. Despite having several active trades, the 0.1 BTC bond and all funds were made available for my immediate withdrawal. What's the point of a 0.1 BTC bond if Paxful makes it immediately available to bannéd users with active trades?
Is Paxful against responsible disclosure or is this all just a coincidence? The vulnerability I reported on 07/06/20 specifically alerted Paxful’s security team to risks of spam and difficulties it might create for users and moderators if moderators did not have special tools that would make this a non-issue. No concerns related to this vulnerability were made apparent until 08/05/20.
For the sake of brevity I'm leaving out a number of other material ongoing and prior issues encountered with Paxful support that impeded my ability to provide seamless service on Paxful's platform. I have gone to great lengths to articulate these issues to support with little/no resolution despite their often simplistic nature.

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.

Particl Marketplace: Where Sellers Meet Buyers

Particl Marketplace: Where Sellers Meet Buyers
People had been speculating since the dawn of crypto when the world’s largest online marketplaces, the ones of the Amazon caliber like eBay, Etsy or AliExpress, and, well, Amazon itself, would start to accept cryptocurrencies. There were a slew of rumors, opinions, and theories thickly interspersed with false reports popping up here and there of Amazon and its little cousins being on the verge of embracing cryptocurrencies. On top of that, someone has actually posted a petition on change.org to add Ether to Amazon as a payment method.
by StealthEX
Long story short, that was a waste of time. High hopes fell flat, and people lost religion. But not all. As the common wisdom goes, when hope dies, action begins. This exposition describes one such effort which tries to bring to fruition the idea of a decentralized marketplace for trading goods and services. And as you might have already figured it out, with a cryptocurrency as a means of payment. So let’s welcome Particl Marketplace and see what it has to offer – and what Amazon has missed.

What is it, in simple words?

Particl Marketplace is an online marketplace where you can trade goods and services. Not a big deal, you may think. However, what distinguishes it from places like Amazon as well as cryptocurrency-enabled marketplaces is the decentralized nature of purchases on Particl. You can think of it as a variety of a decentralized cryptocurrency exchange (aka DEX) where trades are being conducted on-chain. But in case of Particl, it is goods and services that are being traded, not fiat or crypto, with deals on-chain as well, fully encrypted and decentralized.
Particl is a global peer-to-peer privacy-centered marketplace that uses an automated two-party escrow system. It is crypto-agnostic and designed to work with any cryptocurrency, creating a secure, highly-scalable environment supported by a privacy-focused blockchain-based platform. The team behind the project sees its mission in developing “a new decentralized, private and democratic economy” that is governed by the network of its users, with no central authority or middleman getting in the way.
In the project developers’ own words, Particl enables everyone to participate in a free, anonymous exchange of all kinds of goods, without paying any fee and regardless of geographical location. To be sure, you are already thinking about Silk Road and its dark fate, and that the government is going to crack down monumentally on Particl one day. Well, the outcome may vary as the payments on the platform are made using its own cryptocurrency PART, with its laser focus on privacy and anonymity. But more on this later.

How did it grow up?

The development of the Particl project started in early 2017 with the release of the white paper describing the team’s vision for the marketplace, which was shortly followed by a successful seed funding that brought in enough funds ($750,000) to support the development of the project for a year (it turned out sufficient to last for over two years).
These donations helped to establish the Particl Foundation, a non-profit Swiss organization with the goal of providing legal protection for the project to ensure its sustained development and compliance with government regulations. It receives 10% of all the staking rewards generated on the Particl network, making the project self-sustainable and free for most uses.
Unlike other such projects in the crypto arena, Particl has been using its own blockchain from day one, which happened to be July 17, 2017. It was specifically designed to be crypto agnostic by supporting and working with any cryptocurrency. Additionally, it supported the smart contract tech out of the box, giving users an ability to build all kinds of decentralized applications (dApps) that can be directly integrated into the Particl marketplace.
On May 31, 2018, the Particl Marketplace, the Holy Grail of the entire endeavor, was made available for alpha testing on the testnet of the project, which later split into development and stable branches. It went live with the mainnet release of the Particl Open Marketplace on August 12, 2019, which featured Particl Desktop 2.0.0, a client-side application providing user interface and built-in wallet functions.
On November 25, 2019, the Particl Desktop 2.3.0 client was released that enabled Bitcoin payments and marked the introduction of untraceable transactions. With the help of the new in-wallet exchange module, everyone can easily swap their bitcoins for the native PART coin. Moreover, the module allows seamless integration of third-party accountless exchange services right into the marketplace, with StealthEX being one of them.

How is it different from other marketplaces?

The common solution many P2P marketplaces implement to protect buyers and sellers from the other party failing to honor their end of the bargain is through third-party escrow, where the “third-party” in the majority of places and cases is the platform itself that the market participants must mutually trust. In short, it is a single point of failure. And the selling (pardon the pun) point of the entire Particl’s marketplace is its decentralized escrow, which is a thing entirely between the two parties engaged. No middlemen allowed here!
And these are not empty words. Particl implements the concept best known as Mutually Assured Destruction (aptly shortened as MAD), a military doctrine you are certainly familiar with, and probably even afraid of, that consists in a mutual destruction of two belligerent parties in an all-out nuclear holocaust. If you are curious, the idea stems from the game theory and has a lot to do with the Nash Equilibrium, of John Nash’s fame. In a nutshell, Particl removes the need for a trusted escrow agent by introducing MAD escrow smart contracts.
A MAD escrow contract allows to lock funds in a multi-signature address that can be released only if all the parties sign off on the transaction. So both the seller and the buyer lock in the contract an agreed amount for a specified period of time, with the buyer also depositing the payment for the items purchased. The escrowed funds are released when both parties confirm the fulfillment of the agreement. Should one party break the terms, the funds remain locked for good causing a mutual financial loss until both parties agree to sign off.
Another crucial aspect of Particl Marketplace is its end-to-end privacy. The problem with conventional marketplaces acting as an escrow agent is that the communication between the parties should be open to the agent for it to serve as an arbitrator. With Particl, it is no longer required, and all messages between the buyer and the seller are encrypted. Despite being public, only their recipient can decrypt them, which effectively makes messages untraceable.
This is also where the PART coin turns up quite handy. It enables three different privacy modes, and with the most secure mode, the Anon mode, PART transactions utilize the RingCT privacy protocol, which hides both the amount transferred and the identity of the parties transacting. Accordingly, every part of the entire Particl trading environment is thoroughly decentralized, and the full anonymity of market participants is maintained at all times, making the platform a completely trustless marketplace. Big Brother is no longer watching you.
Aside from that, you can stake PART and generate a source of passive income for yourself. Particl uses a custom Proof-of-Stake consensus protocol, allowing you to get a piece of the pie in the form of new coins created at each block according to the scheduled inflation process. The annual inflation rate is initially set to 5% and goes down 1 percentage point every year until it finally floors at 2% indefinitely. Moreover, these rates are a bare minimum as they assume that all PART coins have been staked. Otherwise, the income will be bigger and better as the same rewards are paid to fewer coins.
Additionally, your passive income through staking PART will be augmented by the fees generated through the everyday marketplace operations. Whether it is network fees collected via PART transactions or marketplace listing fees paid by the sellers, all of them contribute to the stakers’ rewards. At the end of the day, staking PART can turn into a profitable business once the Particl platform starts to attract more traffic. In simple words, the more popular the market gets, the more fees it generates, the more coins the stakers earn.
As PART is a standalone cryptocurrency, it can be used outside Particl Marketplace as well. So if you plan on using it for purposes other than eCommerce, it is traded on several exchanges, for example, HitBTC and Bittrex, with more exchanges to list PART in the future. There are native Particl wallets available for storing PART such as Particl Qt with Ledger support, Particl-cli, and Particl Copay Wallet, with the latter available for both the desktop and the mobile. There is also a third-party multicurrency Flare Wallet, enabling cold staking for Particl.
Running Particl is a collective effort, which means no operational costs and no company bagging profits from it. The marketplace buyers don’t pay any commissions other than tiny network confirmation fees, while the sellers are only charged a small listing fee to keep spam listings to a minimum. This creates a highly competitive environment, with the sellers making more profits and the buyers having access to cheaper goods and services as a result.

What’s in the pipeline?

The next major release of the Particl Marketplace should have been Particl Desktop 2.4.0, but it was later rebranded as Particl Desktop 3.0 to reflect its breakthrough nature. It is set for release in the second half of 2020 and will enable the addition of user-created markets and storefronts, effectively turning the Particl marketplace into a network of specialized markets.
And if you think about it, that makes perfect sense. Say, you have a social network account highly merited and full of karma that you want to sell, whatever your reasons might be. Then creating a dedicated market for trading such accounts privately and securely may look extremely appealing to you. Whether it is the right thing to do is another matter, of course.
Kidding aside, it is obviously not about selling or offering something that the society on the whole doesn’t approve of or frowns upon. If you are a freelancer, for example, a graphics designer or a translator, you would be certainly interested in the future freelancer markets – along with your potential employers. Put simply, birds of a feather should flock together.
To keep things in perspective, popular freelancer markets that exist today charge up to 10-20% of what you would get from your client if you negotiated directly. All in all, establishing communities across the marketplace seems to be the next logical step in the natural evolution and growth of the platform. In fact, it is a little surprising that the Particl team didn’t come up with this idea earlier.
Meanwhile, we wish Particl success and good luck in achieving their goals and aspirations.

New and first multi-coin testnet mining pool!

I just posted about my new multi-coin faucet, but I also wanted to announce my new multi-coin testnet mining pool!
I created this pool as I myself was wondering how to get coins for my faucet and knowing I have mining hardware. The only best way would've been to mine them! I searched and could only find one testnet pool and that was only for Bitcoin. So I made my own multi-coin testnet pool and decided to open it up to the public to mine on the testnet!

I apologize for the sudden spike of hashrate on the Dogecoin testnet the other day, that was me as I was mining some coins for my faucet and testing the pool.

Nhom VBC CHROMIA AMA TRANSCRIPT (15/05/2020)

Thai Nhat Minh | Stably:
First of all, can you have a brief introduction about yourself as well as about Chromia? Henrik_hjelte, Sergelubkin
Henrik Hjelte:
Hello. My name is Henrik Hjelte. I am Co-Founder and CEO of Chromia.
I have more than 30 years of experience in programming and a degree in Economics from Uppsala University.
BTW economics and computers = blockchain, so finally found a job that fits me.
I was introduced to the blockchain by the leader of the colored-coins project Alex Mizrahi in 2013
Colored coins project was a very influential thing
It was the first way for user created tokens
bolted on to the only blockchain at the time (almost) bitcoin
We started ChromaWay 2014, with Or Perelman too, to explore if the world was interested in “tokens” and those kind of applications
We worked with enterprise blockchain for some time, but now we are focused on Chromia, a new public platform for mainstream decentralized applications using relational blockchain technology.
Ok, maybe I should tell something about Chromia and not myself too.
Chromia is a better blockchain for building decentralized Apps.
better because it follows the “normal worlds” way of managing data.
A little history: I found a text/description to paste:
Chromia is a brainchild of ChromaWay. ChromaWay has a long record of delivering pioneering projects around the world. We issued Euros on the Bitcoin blockchain with LHV bank, allowed investors to invest in startups in a wholly decentralized way with Funderbeam, digitized the title transfer process with the Swedish land registry, and mediated the green bond market. ChromaWay’s core team created the world’s first protocol to issue tokens already in 2012, when blockchain was called “bitcoin 2.0”. Then ChromaWay introduced the relational model to enterprise blockchains with a consortium database called Postchain. Now Postchain is going public as the foundation for Chromia, a better blockchain for building decentralised Apps.
Chromia is a new public blockchain based on the idea of integrating traditional databases, Relational databases with blockchain security. Chromia is a general purpose blockchain with full smart contract capabilities, just that it is a lot easier to code, even complex applications. You code with an easy to learn new programming language that combines the power of SQL and normal languages but makes it secure in a blockchain context. Up to 1/10 the code-lines vs other blockchains.
If you don’t believe me, check this blog (later, stay in the chat):
https://blog.chromia.com/reasons-for-rell-compactness/
The aim of Chromia is to combine relational databases, which exist in every kind of organization, with blockchains. We want to provide a platform for our users to develop totally decentralized apps securely. Our goal is for Chromia to be seen as the number one infrastructure for decentralized applications.
Think about it: blockchain is about managing data (in a shared context).
And… What do we use to manage data? A Database!
Serge:
Sure! My name is Serge! And I work in Chromia marketing department. Also, I help coordinate various projects inside the company
My background is in Economics and Marketing
Thai Nhat Minh | Stably:
Question 1️⃣
DApp is currently mainly concentrated in the field of games, and its life cycle is basically short, just like the Crypto Kitty is only hot for a while, how to dig the application of DApp in more fields and how to improve the utilization rate of DApp? u/henrik_hjelte u/sergelubkin
Serge:
Good one, let me answer
Gaming is quite a challenging target because good UX is expected, it needs to be fast, responsive, etc. If we can do that, then we can also do all sorts of other stuff.
Also, it lets us experiment with things without a lot of hassle, it’s easier to get users, and so on. It’s also a growing niche within blockchain. You can check our latest game, Mines of Dalarnia https://www.minesofdalarnia.com
We also have Enterprise projects already, for example Green Assets Wallet https://greenassetswallet.org/about that already launched on the first Mainnet version called Bootstrap Net,we also have https://capchap.se built on our tech, more projects like non-profit review platform Impactoria, public land registries, medical projects and so on
Also don’t forget about our fully decentralized social network/forum that is live already on the testnet https://testnet.chromunity.com.
Thai Nhat Minh | Stably:
Question 2️⃣
How will dapp face the world change after the epidemic? u/henrik_hjelte u/sergelubkin
Henrik Hjelte:
Nobody can say for sure, but maybe people will tend to be online more than offline, so demand on online products and dapps as well will increase.
I just came in from an internal demo of a secret project we do, and it can be seen as a way to hang out online (a bit cryptic answer)
There are also interesting use cases of dapps in the medical field.
For example, we participated in the world-wide hackathon Hack for Sweden. Where our submission was to create an app on Chromia blockchain that increases the coordination between countries and hospitals especially during the hard time and COVID19.
Chromia wants to help the European Union (and the world, but we saw problems in the EU…) and its citizens to provide transparency over the necessary medical and protective devices and appliances of which we see shortage during this emergency crisis.
You can watch our promo here https://twitter.com/chromaway/status/1247557274337447938?s=20.
For me it was a fun Hackathon too because for once I got the opportunity to code… I told everyone else I will not do any bossing…
We try to continue this path on medical applications a bit.
Thai Nhat Minh | Stably:
Question 3️⃣
DApps are still not directly embedded in mobile phones like Apps at this moment, and DApps have also been flooded with bet content. How can guests increase the use of DApps and lower the threshold for using DApps? u/henrik_hjelte u/sergelubkin
Serge:
The answer is — better User Experience. We believe that in order for a DApp to be usable and become more widely accepted it has to feel like a normal App. A DApp needs to have quick transactions, scale well & shouldn’t require users to pay for each transaction. This is something that is possible now with using Chromia. It’s an extremely exciting time since we are going to see a new generation of DApps.
On top of that, we think that we might have an ace coming up. We have built a game to demonstrate the powers and possibilities of Chromia. A little bit about the game: In Mines of Dalarnia (https://www.minesofdalarnia.com), players get to explore the vast expanses of interplanetary treasure mines. With an innovative Dalarnia Token system, players can purchase virtual mining plots, and put them up for rent into the community, allowing for real-estate tycoons to earn more Tokens. Mining plots can also undergo their own upgrades, making them more lucrative to explore, as well as a hot property for rental by miners. The game takes advantage of these NFT-based tokens to securely track exchanges, and provide a sense of ownership and wealth to players as they grow their mining and resource empire.
Watch our trailer https://youtu.be/bDXKOp1Asqw and sign-up for the TestNet on the website!
Thai Nhat Minh | Stably:
Question 4️⃣
Many practitioners think that the main reason for restricting the development of DApp is “incomplete infrastructure”. How effective is the current “cross-chain” and “side-chain” solution? u/henrik_hjelte u/sergelubkin
Serge:
Our infrastructure resembles Alibaba Cloud, so a DApp developer just goes and deploys his DApp’s blockchain into it, it’s easy. Also our language Rell https://rell.chromia.com/en/maste is more robust than any other blockchain programming language.Or Azure or AWS
Rell combines the following features:
  1. Relational data modeling and queries similar to SQL. People familiar with SQL should feel at home once they learn the new syntax.
  2. Normal programming constructs: variables, loops, functions, collections, etc.
  3. Constructs which specifically target application backends and, in particular, blockchain-style programming including request routing, authorization, etc.
Rell aims to make programming as convenient and simple as possible. It minimizes boilerplate and repetition. At the same time, as a static type system it can detect and prevent many kinds of defects prior to run-time.
Maybe Henrik wants to add something. :)
Henrik Hjelte:
Yes, I can add some thing
Consider again the real /normal world. What made the apps you use every day? Behind the bank app is a relational database. Web 1.0, “shopping on the internet” was a relational database hooked up to a webpage.
web 2.0: Thefacebook was PhP and MySQL hack
again, a relational database.
So, we aim to make it just as easy to do decentralized apps as normal apps.
Also “the cloud” inspiration is more normal. In Chromia, the dapp developer pays for hosting the application (normally). Not the USERS.
No gas,this is a big usability improvement.
Thai Nhat Minh | Stably:
Question 5️⃣
There are many DApp development platforms on the market. What are the competitive advantages of Chromia? It can be explained in terms of development cost and ease of use that everyone is more concerned about. u/henrik_hjelte u/sergelubkin
Henrik Hjelte:
This what I’m talking about. I think “Ease of use” combined with “Power” is our biggest strength.
Easiness is our core feature thanks to the relational database aspect of our system. Relational databases are run by 85% of the enterprise market at the moment.
And used in 100% of all organizations.
The largest vendor on that market Oracle, has a bigger market cap than bitcoin,
So, this makes it easy for enterprises to integrate our tech stack to their normal systems without the need to redo them, like in most cases where blockchain pilots have failed.
That’s partially why we had success with enterprise customer which are live in the Chromia network.
And: there is a large set of features that relational databases have that alternatives (noSQL) do not have or do not do as well.
And blockchain is very primitive compared to that.
Data indepence, mathematical foundations etc. Large books have been written about it…
On Chromiam It’s very easy for developers to deploy DApps because they already know SQL-style programming. Keep in mind that we worked with customers and developers to build our tech stack while solving problems for them. We didn’t build something unneeded, we had proof of validation from the market.
SQL is top 3rd language in the world (after HTML and javascript).
source: stackoverflow survey 2019, among 90 000 developers…
Top 4 used databases: different flavors of SQL (relational databases)
So, they are used for a reason: Ease of use/programming, power etc.
Also, Rell is our language, is statically typed (means bugs are discovered when programs are written rather than we they run). It is also more compact, up to 1/7 of the code lines of SQL. And have “normal” programming constructs + blockchain programming built in.
Because we require both relational database properties and more security than SQL, currently Rell is the only choice. It is really easy to learn, please go check https://rell.chromia.com/en/maste.
Chromia also provides news to the database developer community….
millions of developers in potential.
OK, bear this in mind when you wonder how we can compete with blockchain X… Blockchain X is a fart in the ocean compare to the SQL world 😊
Bach Tuyet
You have organized many AMA sessions to the international community in general and Vietnam in particular. What do you most want to get after AMA sessions from the community? u/henrik_hjelte
Sergey
I’ll take this one:) our goal is to grow the community
  1. We want people to join our channels such as telegram, twitter, email also our decentralized forum https://testnet.chromunity.com and participate in discussions
  2. We want people to try our dapps such as Mines of Dalarnia
  3. We want to get feedback and understand the most important issues people care about Chromia and the blockchain industry in general
  4. We want to get more developers building on top of Chromia
LBTS:
What was your motivation for creating RELL and not use other languages? What benefits? Why name it RELL also?
Henrik Hjelte:
We have a private/federated relational blockchain called Postchain, and it allows SQL. But that can work in a small environment when you know all parties, and if you are really careful in checking code. But not for a more secure, distributed on the web setup, so we had to make it more secure (Deterministic, statically typed).
In the process, we also took the opportunity to make it cool and nice.
Also: it is simply not possibly to use evm, jvm, or web assembly. We need/want a database in the bottom. Postgresql is our virtual machine. You do not reimplement that…. 10+ years codebase….
Lee:
Being part of the gamer community, I would like to know what you would think about collaborating with a MOBA, RPG or Arcade game or some kind of project?
Henrik Hjelte:
We are already collaborating with some smaller studios. For bigger fish, we want to show them what is completely unique and visionary with Chromia, and we think we need various examples. So, first arcade game MoD (linked above) is one example, it is not the full potential or anything but a start. In this summer, krystopia 2 a puzzle game from Antler Interactive will be released.
What is even cooler is the “demo project” we do together with them, where we will show how a mutliplayer game with real blockchain features will work.
I just saw it an hour ago and was blown away
OH, and there is another studio releasing something very cool. Full logic on chain strategy game. Chain of Alliance.
oyibo pepper:
Do you encourage HACKATHON programs for intending Developers to test their skills and build on RELL
Can you explain more about CHROMIA AMBASSADORS PROGRAM, CAN I BECOME AN AMBASSADOR
Serge:
Yes, you can, but you will need to change your avatar 🤣
Seriously, we are growing our Chromians community if you want to become one please ping our admins in Chromia telegram group.
Also, we are planning virtual hackathons soon, please subscribe to stay updated
Infinite Crypto:
Since the Chromia project is currently working on the Ethereum blockchain ERC20 standard!
But we know that there are a lot of scalability issues with Ethereum, so why would you choose the Ethereum blockchain over other scalable blockchains? Do you have any plans for Mainnet launch of Chromia?
Henrik Hjelte:
ETH is just used in a pre-phase for tokens. We will have our own mainnet tokens interchangable with ETH.
Oyinbo pepper
What’s CHROMIA SSO and SDK, how can I get started
Henrik Hjelte
Both are 3 letters. That is what they have in common.
SDK = software development kit, check docs on https://rell.chromia.com
SSO = single sign on. A unique UX improvement. You approve an app in your wallet (vault) with super ease. no need to remember codes
sso: https://blog.chromia.com/chromia-sso-the-whys-and-the-whats/
We have a fundamentally different model from bitcoin and ethereum and the likes. The blockchain is not run by anonymous computers in basement and student dorms across the world. We have more of known identities, so 51% attacks is protected not by PoW/PoS but other consensus. Please see our whitepaper. Note that we are not noobs when it comes to this, our CTO Alex has published papers in academic journals on consensus etc. from 2013, and done several important ideas for blockchain. Sidechains we think he was first with, tokens too.
Sheron Fernando:
Is there any plan to makes partnership with local cryptocurrency developers from each country to make $CHR usage more worldwide?
Serge:
Yes, we are looking for cooperation with more external developers. Send me a message if you are interested in developing something on Chromia.
Stella:
What are the underlying problems in the Dapps today that can be solved with the Chromia protocol?
Serge:
  1. Scalability — on Chromia your dapp can have unlimited numbers of users thanks to parallel scaling
  2. Easiness of use — you don’t need external wallets, no need to buy crypto to pay for gas etc
  3. Cost — in general to deploy the dapp and to use the dapp
Marcel Lagacé:
Why build this platform? What is Chromia mission? What are the most prominent features of the platform? Can you clarify the use case for this feature?
Henrik Hjelte:
We build the platform to fix the problems with blockchains, that we ourselves have experienced since 2014 (before ethereum existed).
LBTS:
Can you tell us about Chromia developers? How motivated and experienced are they to always deliver the best products?
Henrik Hjelte:
I can tell you that we recruit developers that are really good, from all parts of the world. Vietnam has been a hub because we found many good, so in Ukraine.
How can we say “we have so good developers”? First one thing that is a bit different is that we are pretty experienced in leadership team of development. I do not code much anymore since I’m a CEO. But I do have now over 30 years of experience. Got published and was payed when I was 15. First full-time professional developer job at 18. Have released open-source projects used by 10: s of thousand developers.
And Alex, our CTO is Extremely good. That is why I recruited him to my old startup 2006 or so… So: we have experience to sort out good developers from bad.
Marcel Lagacé:
Does Chromia staking model is different from other staking platform??
What are the beneficial advantages of chromia staking system?
Serge:
The main difference is that we have independent Providers, entities that are not connected. These serious players are exchanges, data centres, professional staking companies. They provide a backbone of the ecosystem and host dapps. Like Amazon servers in the cloud. They cannot have stake bigger than the maximum thus they can’t control the network. This is probably the main difference with classic DPoS networks
Nguyen Duy Bao:
A lot of people will want to know what the strength of Chromia is but I want to know the weaknesses and problems Chromia faces ? How do you plan to solve it?
Henrik Hjelte:
A weakness I guess is weak compared to “competition”. And there are some blockchain projects that got crazy amount of funding. So how can we compete with that, when they can hire more developers for example? Well here is what experience comes into play: More developers does not always increase productivity a lot, it is diminishing returns. You can see many large projects, with 100 of developers fail miserably with no results.
And actually, sometimes true with marketing spend too. It is generally good with money, but if you are a bit clever you can compete also on marketing with less money than your competition.

Weekly Update: 24 crypto assets live on ParJar fiat on/off ramp, FantomVision PWA, $LINK + Voyager, $GHOST for $ESH Hodlers... – 17 Apr - 23 Apr'20
Hiya folks! Hope the shelter-at-home is treating you well. As you might know that the super cyclone Amphan struck Eastern India and Bangladesh day before yesterday. As a result, I went into radio silence for two days. Now that I am back in the grid (albeit with ultra-super slow internet; this post took 4+ hours of retries just to upload pictures), let’s get rolling with the weekly update catch-up series again. Here’s your week at Parachute + partners (17 Apr - 23 Apr'20):

24 cryptocurrencies are now live on ParJar for trading with fiat in Europe, India and UK. This is massive! The new ParJar and #cryptoforeveryone masks look great Clinton! Designers in Parachute, Clinton is looking for fresh original designs for merchandise in the Parachute Shop. You can bag some cool $PAR and discount codes if your art makes it to the store. The #par4par raffle currently has a 500k $PAR prize pool. If you have 10k $PAR in your ParJar, you can claim a ticket. Get in on it! Foo hosted a Parena so that winners can get a taste of the raffle with their prize $PAR. Bose hosted a random TTR trivia this week for a 10k $PAR prize pot.
