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.

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).

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.
Read more: Compound Changes COMP Distribution Rules Following ‘Yield Farming’ Frenzy
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.

morning joe

Stocks are set to end the week on a high note after four of the biggest tech stocks - Apple (NASDAQ:AAPL), Amazon (NASDAQ:AMZN), Facebook (NASDAQ:FB) and Alphabet (GOOG, GOOGL) - reported quarterly results that beat high expectations. Apple easily exceeded estimates on the top and bottom lines, and announced a four-for-one stock split, sending shares past the $400 threshold in after-hours trading. Amazon's sales soared, and operating income nearly doubled compared with the big drop analysts had expected. Facebook posted 11% revenue growth and issued stronger-than-expected sales guidance for the current quarter. Results from Google's parent were a bit murkier, showing the company's first-ever year-over-year decline in advertising revenue, but sales from its cloud-computing segment came in well above expectations. Big Tech has been Wall Street's mainstay this year, and the latest quarterly results look to accelerate that trend. Amazon and Apple are up 65% and 31%, respectively, in 2020, while Facebook and Alphabet each have gained more than 14% over the period. With all four stocks moving higher in after-hours trading, the tech titans likely will add more than $200 billion to their combined market value.
U.S. economy shrank by a third in Q2
The Commerce Department said U.S. gross domestic product collapsed at a 32.9% annualized rate in the second quarter, the steepest decline since the government started keeping records in 1947, as COVID-19 crushed consumer and business spending. Meanwhile, in a sign of a faltering jobs market, the number of workers applying for initial unemployment benefits rose for the second straight week, to 1.43 million, after nearly four months of decreases following a late-March peak. The Q2 economic contraction came as states imposed lockdowns in March and April to contain the coronavirus and then lifted restrictions in May and June, allowing growth to resume. Economists expect the third quarter to show growth, but the summer rise in infections likely will temper gains.
Senate fails to advance jobless benefits extension
Meanwhile, no signs of progress are evident in talks between Republicans and Democrats over a new coronavirus relief bill. The U.S. Senate failed yesterday to advance an effort to extend a $200 per week supplement to unemployment insurance benefits. Senate Republicans and the White House had sought to cut the supplement from $600 through September, after which those collecting unemployment benefits would get 70% of their previous wages when combined with state benefits. While much of the focus has been on the expiration of the additional $600-per-week of unemployment benefits, an eviction moratorium is receiving increasing attention as well.
China factory activity expands for fifth straight month
China’s official manufacturing purchasing managers' index came in better than expected, rising to 51.1 in July from 50.9 in June for its highest reading since March. July marked the fifth consecutive month that the closely watched measure of China's factory activity topped the 50 mark that separates expansion from contraction. Combined with China's official non-manufacturing purchasing managers' index, which indicated a slight deceleration in the service sector, the data suggests China's factories have returned to pre-coronavirus levels but consumer demand remains much weaker, which means inventory is piling up.
Chinese-backed hackers reportedly targeted Moderna for vaccine data
China rejects charges that hackers linked to its government targeted Moderna (NASDAQ:MRNA) to steal data related to research on a coronavirus vaccine. Citing an unnamed U.S. security official, Reuters reported yesterday that Chinese hackers targeted the U.S. biotech firm earlier this year. Moderna said it had been in contact with the FBI and was made aware of the suspected "information reconnaissance activities" by a hacking group mentioned in last week's Justice Department indictment, where two Chinese nationals were accused of spying on the U.S., including three unnamed U.S.-based targets involved in medical research to fight COVID-19. The two other unnamed medical research companies mentioned in the Justice Department indictment are described as biotech companies based in California and Maryland - descriptions that could fit Gilead Sciences (NASDAQ:GILD) and Novavax (NASDAQ:NVAX).

Amazon's $10 billion Internet satellite plan wins FCC approval
While overshadowed by the company's earnings, Amazon.com's (AMZN) tech ambitions got a boost as the FCC approved its $10B plan to put thousands of satellites in the sky to provide high-speed Internet to unserved and underserved areas. The company's Project Kuiper - using 3,200 low Earth orbit satellites - would compete in that area with the Starlink project at SpaceX (SPACE).
Australia to force Google, Facebook to pay for news
Australia will become the first country in the world to force Facebook (FB) and Google (GOOG, GOOGL) to pay publishers for the news content featured on its sites. It will give the companies three months to negotiate fair pay with media businesses there, a move to ensure competition and consumer protection as well as a sustainable media landscape. Other companies are likely to be targeted for similar moves by Australia's government later.
U.K. fraud office charges Airbus subsidiary over Saudi deal
The U.K.'s major economic crimes investigator has charged Airbus' (OTCPK:EADSY) subsidiary GPT Special Project Management and three individuals in connection with a defense contract the country arranged with Saudi Arabia. Airbus says the Serious Fraud Office's investigation related to contractual arrangements that predated its acquisition of the subsidiary. The charges represent a step forward in one of the SFO's most politically sensitive probes, which has been viewed as a potential threat to the U.K.'s relationship with the Saudis.

UNSUBSTANTIATED RUMOUR: I'm hearing reports from normally reliable contacts that there are serious problems with the bitcon.com mining operation, and hackers are involved. Bitcon.com customers getting pissed. They're not mining on BTC or BCH. Looks like it's all over.

LOL. Any comment Salty Roger? MemoryDealers ?
Last block mined on BTC: 583242 (2 days ago)
Last block mined on BCH: 589572 (22 hours ago)
Apparently Emil Oldenburg has gone missing after publicly arguing with Roger, and Shaun Chong has been fired and for now Hans Engren is trying to fix things - and until we see any Proof of Work (i.e. mined blocks) from Bitcon.com it is obvious he is failing, and the hackers are in charge.
This is not a ransom attempt apparently - this is a seek/destroy takedown. All their office computers are down too!
UPDATE
Japan is getting this news right now How long for China?
UPDATE #2 2019-07-03 11:55 UTC
I've been provided with some technical details and it all makes sense:-
Of course /npc is quiet about all of this because of fear, uncertainty, doubt.. no not FUD about this news, but FUD about being banned for speaking against them or questioning the truth or their narratives in the "uncensored subreddit"
UPDATE #3 2019-07-03 13:16 UTC
cash.coin.dance really does need to fix its pie chart code. bitcoin.com still appears there in "blocks mined today" piechart however it's been over 26 hours now since last block mined on BAB.
Please anon sending me messaging stating: "Roger is 51% attacking his own chain as Unknown Miner to double-spend the 3 million BAB he is moving". Don't spread FUD. We know due to centralisation and checkpointing that it's impossible to do this so easily. I have 2 sources who I communicate with daily who are giving me all this info. More news to come, but I want to wait for some sort of signal.
There is now a thread of discussion on /npc will be nice to see how they deny/ignore this one, however attempts have already been made and corrected. Remember BLOCKCHAIN = TRUTH.
UPDATE #4 2019-07-03 14:00 UTC
About those 3 million BAB that moved across the chain.... hmmmmm.... what if Roger moved it, but didn't move it to where he expected, now knows it didn't go where he thought he sent it, and has additional problem of not being able to rollback the blockchain due to "checkpoints" after 10 blocks as other miners are mining including "Unknown Miner" ;) Miner collusion impossible if "Unknown Miner" says "NO". Do we get another emergency ABC release?
C'mon Roger - time to speak out and inform especially those people who idolise you on /npc. Nobody will blame you, easy errors to make. Blame Emil - he hired guy who setup the VPN.
UPDATE #5 2019-07-03 14:18 UTC
Finally coin.dance have fixed their piechart code! Now it's easy for all to see... where is bitcoin.com ?
OK I have been told I'm going to receive documentary evidence about all that has happened around 17:00hs UTC. They've told me they'd rather Roger be straight with his followers in the meantime, but hey - we all know Roger!
UPDATE #6 2019-07-04 05:12 UTC
I fell asleep watching coin.dance waiting for BTC block, sorry folks. I thought my contacts were late due to "variance" in their rendezvous time but no. They told me "will update at 5" and I presumed 17:00. Nope, it's 05:00. They've told me to watch the blockchain for clues, they realise best way to catch out Roger is to produce a series of events, and watch his social media reaction. We've already seen the "everything is OK" narrative at /npc as a block (589720) magically appeared after 26 hours on the BAB chain. In fact things were so good that David Shares was forced to make "dupe post" about it. If David Shares had been a user making a dupe post about a "bad topic" he'd of been banned by David Shares. We've got evidence logs of him banning 3 people in past few weeks just for making duplicate posts on the "we don't censor" subreddit.
Let's examine the blockchain, cause according to /npc "everything is OK".
Number of BTC blocks mined by bitcoin.com since this post was made: 0
Number of BAB blocks mined by bitcoin.com since this post was made: 3 (some are calling these "virtue signalling blocks", and it's a lot cheaper to virtue signal with BAB).
Last BTC block mined is still 583242 (2019-07-01 01:01:38). That's 76 hours without block.
Last BCH blocks mined:-
10 hour gap.
589747
589736
589720
26 hour gap. This post was made.
589572
589520
589487
589479
589442
If you think 3 BAB blocks in 36 hours is OK then I have a SHA257 (that's 1 better than a 256 model) miner to sell you.
"jim-btc we will update within 24 hours. Watch the blockchain. We repeat watch the blockchain". Roger that my secret contacts, thanks!
UPDATE #7 2019-07-04 10:24
I've posted all the block times for both BTC & BAB so you can see this "variance" lie is not going to work for very long.
This is NOT financial advise
If you have BAB - dump that shit faster than a smelly diaper... it's obvious to all except those trapped in the BAB BABble bubble that something really stinks!

Time to discuss the elephant in the room. Nicehash 51% Attacks.

While I've argued for ProgPoW because I'm not a fan of ASIC manufactures because of their malicious business practices, I think we all know the real problem for PoW security, Hashrate Rental sites. Let's go through a short-list of coins that are listed on Nicehash, where hashpower could be bought and then executed a 51% attack.
Monacoin 51%
BitcoinGold 51%
EthereumClassic 51%
Vertcoin 51%
ZenCash(Now Horizen) 51%
BitcoinPrivate 51% (Ethical Hack)

Nicehash has been the #1 to go to "sell" hashpower for whatever coin they support for BTC and other rental services such as miningrigrental. While we cannot prove that this attacks were used by buying hashpower on nicehash, a ethical hacker Geocold lived streamed how easy it was to attack PoW coin BTCP. "using a couple of hundred dollars’ worth of rented hashpower he’d purchased from Nicehash with BTC" (bitcoin.com). We can assume then that other 51% attacks all follow this method.

Step 1. Buy more Hashpower than the current network using rental services
Step 2. moves coins on the true network to other addresses, makes deposits, then withdraws them to a safe addresses
Step 3. broadcast the untruthful chain to the network
Step 4. this reverts the truthful network.
Step 5. Profit.
Shockingly, several crypto-currencies not only were cheap to attack but also had plenty of hash rate for sale on NiceHash with which such an attack could take place. When 51% attacks were considered in the past, most calculations included the cost of hardware, electricity, and maintenance. But this new “rent-a-attack” method is proving dangerous for smaller networks. (ccn.com)
This is what happened to ETC recently. Few people who were using nicehash services commented that they noticed a pay-bump mining ETH-HASH.

One PoW altcoin team has set up a script to constantly monitor their hashrate. In the event of a spike of over 10%, they will be automatically notified. Should the newly added hashrate emanate from an unknown pool, or be in danger of tipping an existing pool over 50%, they have a large quantity BTC on standby with Nicehash ready to purchase their own firepower to counter the attack (bitcoin.com)
Again it shows the only way that people counter this is to over-bid/buy more hashrate.

While I understand PoS doesn't suffer from these type of attacks. However I find it unreasonable to say PoW is flawed because 51% attacks. Hashrental services we not envisioned by Satoshi's PoW. Any actual mining actors not using hash rentals would need a sizable amount of resources to perform a 51% and double-spend even on small cap coins. Nicehash takes your money and doesn't care.

The elephant Crypto needs to deal with it shutting off nicehash and rental services. After the nicehash hack I know I saw a sizable increase in profits because difficulty dropped on so many coins.

IMHO Nicehash needs to turn-off purchasing hashrate and instead turn to "auto-covert" where they mine the coin that's profitable that day and turn into bitcoin for the user. We wouldn't have the chance of 51% attacks.

Decred Journal — June 2018

Note: You can read this on GitHub, Medium or old Reddit to see the 207 links.

Development

The biggest announcement of the month was the new kind of decentralized exchange proposed by @jy-p of Company 0. The Community Discussions section considers the stakeholders' response.
dcrd: Peer management and connectivity improvements. Some work for improved sighash algo. A new optimization that gives 3-4x faster serving of headers, which is great for SPV. This was another step towards multipeer parallel downloads – check this issue for a clear overview of progress and planned work for next months (and some engineering delight). As usual, codebase cleanup, improvements to error handling, test infrastructure and test coverage.
Decrediton: work towards watching only wallets, lots of bugfixes and visual design improvements. Preliminary work to integrate SPV has begun.
Politeia is live on testnet! Useful links: announcement, introduction, command line voting example, example proposal with some votes, mini-guide how to compose a proposal.
Trezor: Decred appeared in the firmware update and on Trezor website, currently for testnet only. Next steps are mainnet support and integration in wallets. For the progress of Decrediton support you can track this meta issue.
dcrdata: Continued work on Insight API support, see this meta issue for progress overview. It is important for integrations due to its popularity. Ongoing work to add charts. A big database change to improve sorting on the Address page was merged and bumped version to 3.0. Work to visualize agenda voting continues.
Ticket splitting: 11-way ticket split from last month has voted (transaction).
Ethereum support in atomicswap is progressing and welcomes more eyeballs.
decred.org: revamped Press page with dozens of added articles, and a shiny new Roadmap page.
decredinfo.com: a new Decred dashboard by lte13. Reddit announcement here.
Dev activity stats for June: 245 active PRs, 184 master commits, 25,973 added and 13,575 deleted lines spread across 8 repositories. Contributions came from 2 to 10 developers per repository. (chart)

Network

Hashrate: growth continues, the month started at 15 and ended at 44 PH/s with some wild 30% swings on the way. The peak was 53.9 PH/s.
F2Pool was the leader varying between 36% and 59% hashrate, followed by coinmine.pl holding between 18% and 29%. In response to concerns about its hashrate share, F2Pool made a statement that they will consider measures like rising the fees to prevent growing to 51%.
Staking: 30-day average ticket price is 94.7 DCR (+3.4). The price was steadily rising from 90.7 to 95.8 peaking at 98.1. Locked DCR grew from 3.68 to 3.81 million DCR, the highest value was 3.83 million corresponding to 47.87% of supply (+0.7% from previous peak).
Nodes: there are 240 public listening and 115 normal nodes per dcred.eu. Version distribution: 57% on v1.2.0 (+12%), 25% on v1.1.2 (-13%), 14% on v1.1.0 (-1%). Note: the reported count of non-listening nodes has dropped significantly due to data reset at decred.eu. It will take some time before the crawler collects more data. On top of that, there is no way to exactly count non-listening nodes. To illustrate, an alternative data source, charts.dcr.farm showed 690 reachable nodes on Jul 1.
Extraordinary event: 247361 and 247362 were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).

ASICs

Update from Obelisk: shipping is expected in first half of July and there is non-zero chance to meet hashrate target.
Another Chinese ASIC spotted on the web: Flying Fish D18 with 340 GH/s at 180 W costing 2,200 CNY (~340 USD). (asicok.comtranslated, also on asicminervalue)
dcrASIC team posted a farewell letter. Despite having an awesome 16 nm chip design, they decided to stop the project citing the saturated mining ecosystem and low profitability for their potential customers.

Integrations

bepool.org is a new mining pool spotted on dcred.eu.
Exchange integrations:
Two OTC trading desks are now shown on decred.org exchanges page.
BitPro payment gateway added Decred and posted on Reddit. Notably, it is fully functional without javascript or cookies and does not ask for name or email, among other features.
Guarda Wallet integrated Decred. Currently only in their web wallet, but more may come in future. Notable feature is "DCR purchase with a bank card". See more details in their post or ask their representative on Reddit. Important: do your best to understand the security model before using any wallet software.

Adoption

Merchants:
BlueYard Capital announced investment in Decred and the intent to be long term supporters and to actively participate in the network's governance. In an overview post they stressed core values of the project:
There are a few other remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed – underscoring that the Decred team and contributors are all about doing the right thing for long term (as manifested in their constitution for the project).
The most encouraging thing we can see is both the quality and quantity of high calibre developers flocking to the project, in addition to a vibrant community attaching their identity to the project.
The company will be hosting an event in Berlin, see Events below.
Arbitrade is now mining Decred.

Media

stakey.club: a new website by @mm:
Hey guys! I'd like to share with you my latest adventure: Stakey Club, hosted at stakey.club, is a website dedicated to Decred. I posted a few articles in Brazilian Portuguese and in English. I also translated to Portuguese some posts from the Decred Blog. I hope you like it! (slack)
@morphymore translated Placeholder's Decred Investment Thesis and Richard Red's write-up on Politeia to Chinese, while @DZ translated Decred Roadmap 2018 to Italian and Russian, and A New Kind of DEX to Italian and Russian.
Second iteration of Chinese ratings released. Compared to the first issue, Decred dropped from 26 to 29 while Bitcoin fell from 13 to 17. We (the authors) restrain ourselves commenting on this one.

Community Discussions

Community stats: Twitter followers 40,209 (+1,091), Reddit subscribers 8,410 (+243), Slack users 5,830 (+172), GitHub 392 stars and 918 forks of dcrd repository.
An update on our communication systems:
Jake Yocom-Piatt did an AMA on CryptoTechnology, a forum for serious crypto tech discussion. Some topics covered were Decred attack cost and resistance, voting policies, smart contracts, SPV security, DAO and DPoS.
A new kind of DEX was the subject of an extensive discussion in #general, #random, #trading channels as well as Reddit. New channel #thedex was created and attracted more than 100 people.
A frequent and fair question is how the DEX would benefit Decred. @lukebp has put it well:
Projects like these help Decred attract talent. Typically, the people that are the best at what they do aren’t driven solely by money. They want to work on interesting projects that they believe in with other talented individuals. Launching a DEX that has no trading fees, no requirement to buy a 3rd party token (including Decred), and that cuts out all middlemen is a clear demonstration of the ethos that Decred was founded on. It helps us get our name out there and attract the type of people that believe in the same mission that we do. (slack)
Another concern that it will slow down other projects was addressed by @davecgh:
The intent is for an external team to take up the mantle and build it, so it won't have any bearing on the current c0 roadmap. The important thing to keep in mind is that the goal of Decred is to have a bunch of independent teams on working on different things. (slack)
A chat about Decred fork resistance started on Twitter and continued in #trading. Community members continue to discuss the finer points of Decred's hybrid system, bringing new users up to speed and answering their questions. The key takeaway from this chat is that the Decred chain is impossible to advance without votes, and to get around that the forker needs to change the protocol in a way that would make it clearly not Decred.
"Against community governance" article was discussed on Reddit and #governance.
"The Downside of Democracy (and What it Means for Blockchain Governance)" was another article arguing against on-chain governance, discussed here.
Reddit recap: mining rig shops discussion; how centralized is Politeia; controversial debate on photos of models that yielded useful discussion on our marketing approach; analysis of a drop in number of transactions; concerns regarding project bus factor, removing central authorities, advertising and full node count – received detailed responses; an argument by insette for maximizing aggregate tx fees; coordinating network upgrades; a new "Why Decred?" thread; a question about quantum resistance with a detailed answer and a recap of current status of quantum resistant algorithms.
Chats recap: Programmatic Proof-of-Work (ProgPoW) discussion; possible hashrate of Blake-256 miners is at least ~30% higher than SHA-256d; how Decred is not vulnerable to SPV leaf/node attack.

Markets

DCR opened the month at ~$93, reached monthly high of $110, gradually dropped to the low of $58 and closed at $67. In BTC terms it was 0.0125 -> 0.0150 -> 0.0098 -> 0.0105. The downturn coincided with a global decline across the whole crypto market.
In the middle of the month Decred was noticed to be #1 in onchainfx "% down from ATH" chart and on this chart by @CoinzTrader. Towards the end of the month it dropped to #3.

Relevant External

Obelisk announced Launchpad service. The idea is to work with coin developers to design a custom, ASIC-friendly PoW algorithm together with a first batch of ASICs and distribute them among the community.
Equihash-based ZenCash was hit by a double spend attack that led to a loss of $450,000 by the exchange which was targeted.
Almost one year after collecting funds, Tezos announced a surprise identification procedure to claim tokens (non-javascript version).
A hacker broke into Syscoin's GitHub account and implanted malware stealing passwords and private keys into Windows binaries. This is a painful reminder for everybody to verify binaries after download.
Circle announced new asset listing framework for Poloniex. Relevant to recent discussions of exchange listing bribery:
Please note: we will not accept any kind of payment to list an asset.
Bithumb got hacked with a $30 m loss.
Zcash organized Zcon0, an event in Canada that focused on privacy tech and governance. An interesting insight from Keynote Panel on governance: "There is no such thing as on-chain governance".
Microsoft acquired GitHub. There was some debate about whether it is a reason to look into alternative solutions like GitLab right now. It is always a good idea to have a local copy of Decred source code, just in case.
Status update from @sumiflow on correcting DCR supply on various sites:
To begin with, none of the below sites were showing the correct supply or market cap for Decred but we've made some progress. coingecko.com, coinlib.io, cryptocompare.com, livecoinwatch.com, worldcoinindex.com - corrected! cryptoindex.co, onchainfx.com - awaiting fix coinmarketcap.com - refused to fix because devs have coins too? (slack)

About This Issue

This is the third issue of Decred Journal after April and May.
Most information from third parties is relayed directly from source after a minimal sanity check. The authors of Decred Journal have no ability to verify all claims. Please beware of scams and do your own research.
The new public Matrix logs look promising and we hope to transition from Slack links to Matrix links. In the meantime, the way to read Slack links is explained in the previous issue.
As usual, any feedback is appreciated: please comment on Reddit, GitHub or #writers_room. Contributions are welcome too, anything from initial collection to final review to translations.
Credits (Slack names, alphabetical order): bee and Richard-Red. Special thanks to @Haon for bringing May 2018 issue to medium.

Time to discuss the elephant in the room. Nicehash 51% Attacks.

While I've argued for ProgPoW because I'm not a fan of ASIC manufactures because of their malicious business practices, I think we all know the real problem for PoW security, Hashrate Rental sites. Let's go through a short-list of coins that are listed on Nicehash, where hashpower could be bought and then executed a 51% attack.
Monacoin 51%

Decred Journal — May 2018

Note: New Reddit look may not highlight links. See old look here. A copy is hosted on GitHub for better reading experience. Check it out, contains photo of the month! Also on Medium

Development

dcrd: Significant optimization in signature hash calculation, bloom filters support was removed, 2x faster startup thanks to in-memory full block index, multipeer work advancing, stronger protection against majority hashpower attacks. Additionally, code refactoring and cleanup, code and test infrastructure improvements.
In dcrd and dcrwallet developers have been experimenting with new modular dependency and versioning schemes using vgo. @orthomind is seeking feedback for his work on reproducible builds.
Decrediton: 1.2.1 bugfix release, work on SPV has started, chart additions are in progress. Further simplification of the staking process is in the pipeline (slack).
Politeia: new command line tool to interact with Politeia API, general development is ongoing. Help with testing will soon be welcome: this issue sets out a test plan, join #politeia to follow progress and participate in testing.
dcrdata: work ongoing on improved design, adding more charts and improving Insight API support.
Android: design work advancing.
Decred's own DNS seeder (dcrseeder) was released. It is written in Go and it properly supports service bit filtering, which will allow SPV nodes to find full nodes that support compact filters.
Ticket splitting service by @matheusd entered beta and demonstrated an 11-way split on mainnet. Help with testing is much appreciated, please join #ticket_splitting to participate in splits, but check this doc to learn about the risks. Reddit discussion here.
Trezor support is expected to land in their next firmware update.
Decred is now supported by Riemann, a toolbox from James Prestwich to construct transactions for many UTXO-based chains from human-readable strings.
Atomic swap with Ethereum on testnet was demonstrated at Blockspot Conference LATAM.
Two new faces were added to contributors page.
Dev activity stats for May: 238 active PRs, 195 master commits, 32,831 added and 22,280 deleted lines spread across 8 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: rapid growth from ~4,000 TH/s at the beginning of the month to ~15,000 at the end with new all time high of 17,949. Interesting dynamic in hashrate distribution across mining pools: coinmine.pl share went down from 55% to 25% while F2Pool up from 2% to 44%. [Note: as of June 6, the hashrate continues to rise and has already passed 22,000 TH/s]
Staking: 30-day average ticket price is 91.3 DCR (+0.8), stake participation is 46.9% (+0.8%) with 3.68 million DCR locked (+0.15). Min price was 85.56. On May 11 ticket price surged to 96.99, staying elevated for longer than usual after such a pump. Locked DCR peaked at 47.17%. jet_user on reddit suggested that the DCR for these tickets likely came from a miner with significant hashrate.
Nodes: there are 226 public listening and 405 normal nodes per dcred.eu. Version distribution: 45% on v1.2.0 (up from 24% last month), 39% on v1.1.2, 15% on v1.1.0 and 1% running outdaded versions.

ASICs

Obelisk team posted an update. Current hashrate estimate of DCR1 is 1200 GH/s at 500 W and may still change. The chips came back at 40% the speed of the simulated results, it is still unknown why. Batch 1 units may get delayed 1-2 weeks past June 30. See discussions on decred and on siacoin.
@SiaBillionaire estimated that 7940 DCR1 units were sold in Batches 1-5, while Lynmar13 shared his projections of DCR1 profitability (reddit).
A new Chinese miner for pre-order was noticed by our Telegram group. Woodpecker WB2 specs 1.5 TH/s at 1200 W, costs 15,000 CNY (~2,340 USD) and the initial 150 units are expected to ship on Aug 15. (pow8.comtranslated)
Another new miner is iBelink DSM6T: 6 TH/s at 2100 W costing $6,300 (ibelink.co). Shipping starts from June 5. Some concerns and links were posted in these two threads.

A new mining pool is available now: altpool.net. It uses PPLNS model and takes 1% fee.
Another infrastructure addition is tokensmart.io, a newly audited stake pool with 0.8% fee. There are a total of 14 stake pools now.
Exchange integrations:
OpenBazaar released an update that allows one to trade cryptocurrencies, including DCR.
@i2Rav from i2trading is now offering two sided OTC market liquidity on DCUSD in #trading channel.
Paytomat, payments solution for point of sale and e-commerce, integrated Decred. (missed in April issue)
CoinPayments, a payment processor supporting Decred, developed an integration with @Shopify that allows connected merchants to accept cryptocurrencies in exchange for goods.

Adoption

New merchants:
An update from VotoLegal:
michae2xl: Voto Legal: CEO Thiago Rondon of Appcívico, has already been contacted by 800 politicians and negotiations have started with four pre-candidates for the presidency (slack, source tweet)
Blockfolio rolled out Signal Beta with Decred in the list. Users who own or watch a coin will automatically receive updates pushed by project teams. Nice to see this Journal made it to the screenshot!
Placeholder Ventures announced that Decred is their first public investment. Their Investment Thesis is a clear and well researched overview of Decred. Among other great points it noted the less obvious benefit of not doing an ICO:
By choosing not to pre-sell coins to speculators, the financial rewards from Decred’s growth most favor those who work for the network.
Alex Evans, a cryptoeconomics researcher who recently joined Placeholder, posted his 13-page Decred Network Analysis.

Marketing

@Dustorf published March–April survey results (pdf). It analyzes 166 responses and has lots of interesting data. Just an example:
"I own DECRED because I saw a YouTube video with DECRED Jesus and after seeing it I was sold."
May targeted advertising report released. Reach @timhebel for full version.

Community Discussions

Community stats: Twitter 39,118 (+742), Reddit 8,167 (+277), Slack 5,658 (+160). Difference is between May 5 and May 31.
Reddit highlights: transparent up/down voting on Politeia, combining LN and atomic swaps, minimum viable superorganism, the controversial debate on Decred contractor model (people wondered about true motives behind the thread), tx size and fees discussion, hard moderation case, impact of ASICs on price, another "Why Decred?" thread with another excellent pitch by solar, fee analysis showing how ticket price algorithm change was controversial with ~100x cut in miner profits, impact of ticket splitting on ticket price, recommendations on promoting Decred, security against double spends and custom voting policies.
@R3VoLuT1OneR posted a preview of a proposal from his company for Decred to offer scholarships for students.
dcrtrader gained a couple of new moderators, weekly automatic threads were reconfigured to monthly and empty threads were removed. Currently most trading talk happens on #trading and some leaks to decred. A separate trading sub offers some advantages: unlimited trading talk, broad range of allowed topics, free speech and transparent moderation, in addition to standard reddit threaded discussion, permanent history and search.
Forum: potential social attacks on Decred.
Slack: the #governance channel created last month has seen many intelligent conversations on topics including: finite attention of decision makers, why stakeholders can make good decisions (opposed to a common narrative than only developers are capable of making good decisions), proposal funding and contractor pre-qualification, Cardano and Dash treasuries, quadratic voting, equality of outcome vs equality of opportunity, and much more.
One particularly important issue being discussed is the growing number of posts arguing that on-chain governance and coin voting is bad. Just a few examples from Twitter: Decred is solving an imagined problem (decent response by @jm_buirski), we convince ourselves that we need governance and ticket price algo vote was not controversial, on-chain governance hurts node operators and it is too early for it, it robs node operators of their role, crypto risks being captured by the wealthy, it is a huge threat to the whole public blockchain space, coin holders should not own the blockchain.
Some responses were posted here and here on Twitter, as well as this article by Noah Pierau.

Markets

The month of May has seen Decred earn some much deserved attention in the markets. DCR started the month around 0.009 BTC and finished around 0.0125 with interim high of 0.0165 on Bittrex. In USD terms it started around $81 and finished around $92, temporarily rising to $118. During a period in which most altcoins suffered, Decred has performed well; rising from rank #45 to #30 on Coinmarketcap.
The addition of a much awaited KRW pair on Upbit saw the price briefly double on some exchanges. This pair opens up direct DCR to fiat trading in one of the largest cryptocurrency markets in the world.
An update from @i2Rav:
We have begun trading DCR in large volume daily. The interest around DCR has really started to grow in terms of OTC quote requests. More and more customers are asking about trading it.
Like in previous month, Decred scores high by "% down from ATH" indicator being #2 on onchainfx as of June 6.

Relevant External

David Vorick (@taek) published lots of insights into the world of ASIC manufacturing (reddit). Bitmain replied.
Bitmain released an ASIC for Equihash (archived), an algorithm thought to be somewhat ASIC-resistant 2 years ago.
Three pure PoW coins were attacked this month, one attempting to be ASIC resistant. This shows the importance of Decred's PoS layer that exerts control over miners and allows Decred to welcome ASIC miners for more PoW security without sacrificing sovereignty to them.
Upbit was raided over suspected fraud and put under investigation. Following news reported no illicit activity was found and suggested and raid was premature and damaged trust in local exchanges.
Circle, the new owner of Poloniex, announced a USD-backed stablecoin and Bitmain partnership. The plan is to make USDC available as a primary market on Poloniex. More details in the FAQ.
Poloniex announced lower trading fees.
Bittrex plans to offer USD trading pairs.
@sumiflow made good progress on correcting Decred market cap on several sites:
speaking of market cap, I got it corrected on coingecko, cryptocompare, and worldcoinindex onchainfx, livecoinwatch, and cryptoindex.co said they would update it about a month ago but haven't yet I messaged coinlib.io today but haven't got a response yet coinmarketcap refused to correct it until they can verify certain funds have moved from dev wallets which is most likely forever unknowable (slack)

Summary: pitfalls of paper wallets

Pitfalls and solutions of paper wallets

Creating paper wallets:

Problematic action: Create a paper wallet on a paper wallet service website without disconnecting from the internet. Reason: It's extremely insecure for many reasons, some being 1) the website is hacked with generated private keys sent to the hacker; 2) there may be malware in the browser or in the operating system that sends the private keys to the hacker. Solution: The bottom line is to disconnect the internet before creating the paper wallet. It's not secure enough because 1) the malware can save the private keys and wait for internet connection to send them out; 2) the malware can interfere with the generation process itself and give you a private key that is already known to the hacker, which is called backdooring the random number generator; 3) the private keys may exist on the hard disk therefore may be extracted by malware or after the computer is disposed. Better solution: Download the paper wallet app from an online computer. Copy it to an offline computer via a flash drive. Run it from there. Best solution: Use a live operating system, such as a Linux live CD, to run the paper wallet app. This is not ultimately bullet-proof, especially for high-value targets, because there exist malware that can hide in the BIOS and firmware of your computer and can infect your live operating system. It should be secure enough for average Joes.
Problematic action: Create a paper wallet without serious verifications. Reason: There may be incompatible issues with operating systems and browsers. Solution: Run tests on various operating systems and various browsers before putting BTC in. Make sure the generated private keys are identical. This applies to regular paper wallets and BIP38 paper wallets. Make sure the decrypted BIP38 keys are correct.
Problematic action: Create a brain wallet created by bitaddress.org or other brain wallets without key stretching. Reason: It has been proven insecure. Solution: Use WarpWallet or other brain wallets with key stretching, e.g., scrypt, bcrypt, sha512crypt, pbkdf2, and so on.

Printing paper wallets:

Problematic action: Use a wireless printer. Reason: It's insecure because wireless networks are insecure. Solution: Use a wired printer.
Problematic action: Use an advanced printer, which has internal storage, such as a hard drive. Reason: It is insecure because the private key of the paper wallet printed may be stored on the internal storage, therefore may be recovered if the printer is sold or scrapped. Solution: Use a dumb printer. Or keep the printer locked up and never sell or scrap it. Or smash the printer, including and especially the internal storage.
Problematic action: Leave the printer open for other people to access after printing without turning it off. Reason: It's insecure because the private key printed may still be in the memory of the printer. Solution: Turn the printer off after printing.
Problematic action: Leave the computer untreated after printing. Reason: It's insecure because the printer driver and/or operating system may be keeping copies of the documents you print in some sort of "spool" or print queue. Solution: Use a live operating system, such as a Linux live CD, to print.
Problematic action: Use a shared printer (at work or school, for example). Reason: It's insecure because 1) the printer may have a glitch and someone else may get your printouts; 2) the printing jobs may be centrally logged. Solution: Don't. Use your own printer.
Problematic action: Use a printer to print the private key or the QR code of the private key. Reason: See above. Solution 1: Don't use a printer for private key stuff. Hand-write the private key. Hand-draw the QR code if you and the helping checker are patient enough. Or ignore the QR code since hand-drawing the QR code of the private key may be too time-consuming. Double check. Then check it again, preferably on a different day. Get someone you trust to check it. Then get him/her to check it again, preferably on a different day. (Testing the private key in a wallet app can make it sure. But it comes with risks.) Solution 2: Don't use a printer for private key stuff. Use brain wallet. Write down the passphrase and the relevant information, e.g., the name of the tool used, e.g., WarpWallet, and the instructions. Store it the same way as a paper wallet. Save and store some copies of the tool, in case the future versions become incompatible. (There are pitfalls for creating man-made passphrases. It is beyond the scope of this post. In a nutshell, don't create the passphrase (solely) with your brain, and don't keep the passphrase (solely) with your brain.)

Spending from paper wallets:

Problematic action: Import a paper wallet private key into a wallet app, then spend directly from the paper wallet address.
Mistake: Expect the paper wallet automatically receives/holds changes, similar to a real-life wallet, which may not be the case. Reason: Early wallet apps didn't handle the changes correctly. The changes became the transaction fees of the miners. There is a misunderstanding of how Bitcoin works. There is no account balance of any kind in Bitcoin. There is only Unspent Transaction Outputs (UTXOs). The receiving addresses of changes, which will become the new UTXOs, must be specified when BTC is spent. Otherwise, the changes will automatically become the transaction fees. This depends on the implementation of the wallet app, which should not be trusted.
Mistake: Think nothing is wrong if changes are handled correctly. Reason: It's called address reuse, which is not recommended in Bitcoin because 1) it reduces anonymity of both the sender and all the consecutive receivers; 2) it reduces the security by exposing the public key, which is vulnerable to quantum computing. Addresses are hashes of public keys, which are safe from quantum computing.
Mistake: Destroy the paper wallet after it's imported into an HD wallet, thinking that it has become a part of the HD wallet and it's safe to destroy because the master seed of the HD has been backed up. Reason: It is not a part of the HD wallet. If the paper wallet (the paper) is destroyed and the app is uninstalled, the BTC is gone even if the HD wallet is recovered from its master seed.
The right way: Spend (transact) all BTC in a paper wallet to an address of your wallet app. It is called "sweeping", which is completely different from importing the private key. Spend BTC from there. After all the spending is finished, create a new paper wallet and transact all the remaining BTC to it. Store the new paper wallet. Keep the old one for future reference, or destroy it if you don't want the trace.

Destroying paper wallets:

Problematic action: Destroy a paper wallet after it is used. Reason: You may need to prove you had control of that address some day, e.g., for taxation purpose. In the case of a chain split, you may have a balance on the other chain. Solution: Don't ever destroy a paper wallet. Keep it on file. Mark it with the relevant information, e.g., "Used in April 2017". Unless you don't want to be tied to the address.

Pitfalls not specific to but more likely happen to paper wallets:

Problematic action: Google a famous wallet app, click the first link or the sponsored link, download/install it, and use it, without serious research. Reason: It's insecure because the wallet app may be a scam. Solution: Do thorough research prior to deciding which wallet app to use. Find the official site prior to downloading/installing it.
Additions and corrections are welcome.
Edit: multiple editing for additions, corrections, and clarifications.
Disclaimer: Although I set off to make this article in order to use paper wallet safely, I ended up not using it. Some of the solutions are collected from the internet. Some are my untested ideas. Use the article at your risk.

Well, promoting wasn’t enough for us, so we decided to create the UBAI, the first online university developing practical courses on blockchain.
Get familiar with Ethereum, its founding principles and major improvements/limitations upon the initial Bitcoin Blockchain!
Did you know that due to the nature of the cryptographic community from which cryptocurrencies have been developed, it is only natural that the adoption of cryptocurrencies in the digital sphere has dwarfed that in the traditional business world? Cryptocurrency adoption has firmly permeated the online gaming sphere with offerings such as Experience points (XP) for purchasing incentives in games and educational content, as well as GameCredits (GAME), which aims to be a universal currency for gamers worldwide and STORM, a kind of Blockchain Mechanical Turk, a crowdsourcing Internet marketplace. In the online gambling space, Funfair (FUN) aims to be the go-to currency for all online gaming, and Edgeless (EDG) supposedly offers a gambling experience with no edge for the house, a project all gamblers would surely welcome and support.
Cryptocurrency projects have already provided use cases for conventional businesses and enabled existing commercial operations to improve their performance with the implementation of Blockchain technology. Thus far, Bitcoin is the cryptocurrency that has most readily made inroads into the public consciousness. Microsoft, for example, has begun to accept Bitcoin payments in Windows and XBox stores, and Expedia has teamed up with Coinbase to allow Bitcoin to be used to book hotel rooms. Much like Iconomy in the crypto asset management sphere, NapoleonX (NPX), is allowing crypto investors to buy into Decentralized autonomous funds which focus on conventional markets. As we have already covered, one of the main reasons that Blockchain technology is causing so much excitement is because of the great number of ways the technology might be developed and applied in business.
The Canadian-Russian boy genius named Vitalik Buterin first envisaged the next stage in Blockchain technology as a scripting language for Bitcoin. But this particular idea failed to reach a consensus with the community. That is what stimulated development of a totally new platform with a more general type of language. Initial development on the Ethereum project began in Spring 2014 with the core team of Vitalik Buterin, Mihai Alisie, Anthony DiIorio, and Charles Hoskinson, working through the Swiss company EthSuisse. Subsequently, the Ethereum Foundation was created in the run up to the July 2014 crowd sale. Then, the Ethereum project’s currency Ether was distributed to participants who purchased the token with Bitcoin.
The initial questions about the security of the project were proven to be warranted after an infamous entity called the DAO (Decentralized Autonomous Organization) led to the loss of $50 million of the $150 million dollars raised in the Ethereum crowdsale. The Ethereum Blockchain then underwent a very contentious hard fork resulting in the Ethereum, ETH, we know today being separated from its parent chain, Ethereum Classic, ETC. By the end of 2016, the Ethereum Blockchain had forked twice more resulting in increased DDoS protection, that de-bloated its Blockchain, and thwarted further spam attacks by hackers.
The true cost of the financial crisis for the world economy is still being calculated and may never actually be known, but conservative estimates put the cost at approximately $20,000 per America citizen. Satoshi Nakamoto, the anonymous creator of the most famous and infamous digital currency, sought to create a means of transmitting value that did not require a trusted third party to oversee the transaction or guarantee the value. By using distributed ledger technology on the Blockchain he laid the foundation for a trustless decentralized financial system that did not rely on central banks to mediate transactions. This is a “peer-to-peer version of electronic cash…. sent directly from one party to another without going through a financial institution”. With no trusted third party, each individual becomes a self-sovereign, one-person-bank, responsible for his or her own transactions and security.
The Ether token’s authenticity is guaranteed by its Blockchain, which is a continuously growing list of records connected and secured using cryptography. Like Bitcoin, the Ethereum Network is an open and distributed ledger that records transactions between two people in a confirmable and permanent way. The Ether token is superior to bitcoin in that its blocktime is approximately 15 seconds compared to 10 minutes with Bitcoin. Mining generates new coins at a usually consistent rate, and the average transaction cost in December 2017 was $0.33 compared to $23 for Bitcoin. As alluded to above, Ethereum initially aimed to become both a decentralized internet and a decentralized app store supporting a new kind of app (dapp). In order for the network to function correctly, a novel piece of code “ether” was created in order to pay for the computational power needed to run an application on the Ethereum network. Ether is a digital bearer asset like BTC, and does not need a third party to verify or mediate transactions. “ERC-20 Token: The Ethereum Request for Comment -20 token is standard set of rules used for smart contracts on the Ethereum Blockchain for executing new tokens. It defines a uniform set of rules on how a new token will function within the Ethereum Blockchain. The creation of this token has made it very easy for start-up companies to create their own token within the Ether ecosystem. That was a very significant advancement that caused the 2017 ICO boom in newly issued tokens.
Monero: This fork of Bitcoin is focused on privacy and decentralization. It obfuscates the sender and recipient’s addresses, as well as the amount of the transaction. The original Monero (the name is Esperanto for “coin”) author, Nicolas van Saberhagen, sought to make mining rewards more egalitarian as an additional benefit of being part of the Monero ecosystem. The very private nature of the Monero architecture, which mixes sender “ring signatures” with many others, makes the deciphering of the destination and recipient address increasingly difficult. This has made the Monero cryptocurrency the go-to coin for illicit transactions on the Dark web. There is, however, another way to look at this. Although Monero’s intensely private nature and deliberate obfuscation of transaction destinations and sources is undoubtedly used for criminal and corrupt purposes, the exact opposite effect may occur if its privacy characteristics are placed within the context of third world countries where corruption is already rife. In developing countries, it has proven much easier for people to obtain devices with an internet connection than it is for them to open a bank account. With 2 billion people worldwide without a bank account, much of them in Sub-Saharan Africa, privacy coins like Monero could play a key role in distributing aid to the needy without having to deal with any potentially corrupt and inefficient organizations or state institutions standing in between.
Ripple: Ripple is well-known as one of the very first big Blockchain projects. In fact, its predecessor, RipplePay dates all the way back to 2004. The modern version of the Ripple payment protocol (conceived by Jared McCaleb and built by Arthur Britto and David Schwartz) enables instant peer-to-peer transfer of money. The protocol and the facility to avoid the banking system, results in drastically reduced fees and transaction times compared to international transfers by conventional banking methods. Ripple is currently known as the cryptocurrency of the financial services industry, with major involvement by Santander, American Express and RBS, amongst many others. Ripple has also teamed up with Moneygram to speed up the process of cross-border payments. Ripple is aiming to send money across national lines “as quickly as information” in the words of its CEO Brad Garlinghouse. The almost laughable inefficiencies and delays in sending money to friends or loved ones in foreign countries is a major pain point for banking customers the world over. Now, with the implementation of Blockchain technology through Ripple’s XRapid initiative in partnership with Moneygram, international transfer times will go from being measured in days to being measured in seconds.
NEO: This is often described as the “Chinese Ethereum”. NEO is similar to Ethereum in that it is a Blockchain platform that is designed to be a scalable platform for the construction of decentralized applications. The NEO Blockchain project was founded by Da Hongfei in 2014. Like Ether (ETH) in the Ethereum network, the NEO token is the base asset of the NEO Blockchain. But unlike Ether, it is indivisible, and it accrues a GAS token when stored in a wallet. The GAS token can be used to pay transaction fees on the NEO Blockchain. The NEO cryptocurrency was rebranded from Antshares in 2017, and has started to produce highly successful ICOs on its platform, most notably Ontology (ONT) and RPX which will make use of the NEP-5 token. In the immediate aftermath of rebrand from Antshares, the all-encompassing vision of NEO 2.0 was laid out as follows: “We hope the platform can be used for different front-end scenarios, such as the Digital asset wallet, Forum, Voting, Profile management and Mobile applications. The platform also features an open API that can be used for integration with other systems.” One of the main alterations made to the NEO project was the addition of more up-to-date digital identity management protocols which employed Public Key Infrastructure(PKI)X.509 digital identity standards. NEO’s verification of identity when issuing digital identities includes fingerprint, voice and facial feature authentication methods.
IOTA’s code architecture is not in the same mold of Bitcoin or Ethereum, both of which could be described as existing on and making use of a Blockchain to order their transaction history. IOTA, and its token, the MIOTA, are embedded in a code structure called “The Tangle” which is a form of Direct Acyclic Graph data architecture. This particular architecture enables the code to function with no fixed block and each transaction carries its own proof of work. These types of transactions are enabled by “storing the most recent transactions in a fast cache, and by using checkpoints such that older transactions cannot be references. Thus, the system can be made as fast as Bitcoin, or faster”. IOTA’s main use case is for the transmission of information and value between Internet of Things enabled devices, in an automated manner. This project is truly one oriented toward the future, when many more IoT devices will be online, and there is a great need for such devices to communicate and transact without any human intervention. One weak point in DAG code architecture is that much less than a 51% attack is sufficient to compromise the network. It would be theoretically possible to bring about double spending on a DAG network with a 34% attack.
TenX (PAY) TenX was founded in 2014 as part of a PayPal incubator program. It sought to bridge the gap between Blockchain assets and everyday commerce, providing an efficient solution for the liquidity problems of many cryptocurrencies. The project will eventually be centered around a debit card that makes use of the COMIT protocol that enables many different Blockchains to interact with one another without having to issue a different token. That could be another milestone event in the crypto ecosystem. The project roadmap presented to investors began with the ICO in July 2017. They famously raised $34 Million in the first 7 minutes. The roadmap will conclude when they obtain their banking license in the middle of 2020. At that point they also aim to issue FIAT tokens fully backed and issued by a government. So far, the TenX project is on course to meet its stated targets. They brought out their highly rated IOS and web apps at the end of 2017. This serves as a fantastic example of how a well-run ICO can help both the investors and the startup streamline the capitalization process to the benefit of all parties involved.
Influence upon Traditional Merchants around the world. Due to the inherent volatility of cryptocurrency, the adoption of crypto payment methods by traditional businesses has generally been slower than in the online sphere. Although some major companies have in fact begun to come around to the idea of integrating digital currencies into their methods of accepting payments, the volatility of crypto is still a serious impediment for most. Microsoft has led the way by incorporating Bitcoin payment systems into the Window Store, as well as adding the ability for game players to purchase credit on the Xbox live network with Bitcoin. Overstock began accepting Bitcoin payments on January 9th, 2014, and saw a significant uptick in orders immediately. They received 900 new orders for $126,000 worth of BTC. Electronic retailer NewEgg, and online gaming site Zynga, also now take Bitcoin payments. There are even certain Subway outlets in South America that have started to accept Bitcoin as a method of payment too. On a far smaller scale, Coingate has partnered with Prestashop, to take Europe to the verge of a widescale cryptocurrency payment method. Merchants of any size need only apply for a Coingate account, and then have a crypto payment module installed, in order to accept payment in Bitcoin, BCash, Ether, Litecoin and nearly 50 other cryptocurrencies. The price is locked in immediately at the time of the transaction, which solves the volatility issue, and the whole process can be completed without the merchant having to deal in anything other than Euros. CryptoCredit card projects Monaco and TenX help to bridge the gap between the worlds of fiat and crypto, allowing a card holder to spend their cryptocurrency anywhere in the world.
Decentralization & Our Financial World In the Financial World, decentralization would radically alter the roles of, and creation of value by, our modern day ‘too-big-to-fail’ financial institutions. The capping of the supply of most major cryptocurrencies is itself an idea nothing short of revolutionary, in the truest sense of the word. All developed economies are oriented around a Central Bank that, through the system of fractional reserve banking, has power to create loans or investments and accept deposits, but is only required to hold reserves equal to 10% of its total liabilities. This in effect empowers central banks to print money as they see fit, a mechanism which gives central banks massive power in contemporary society. Any move toward decentralized ledgers, and any number of finite decentralized currencies, would upset the balance of power between central banks and the individual in a way that has never occurred before. The role of central banks in the economy, and the traditional means of solving common financial problems by having the central bank manipulate the money supply, for example, would need to be radically rethought. Consider the recently used machinations such as quantitative easing, negative interest rates, etc. These are present-day “solutions” that would no longer be able to be applied to the economic and financial problems they are attempting to solve.
If Blockchain technology was meaningfully deployed in the political arena it is conceivable that political corruption and vote-rigging could be severely curtailed or even eradicated. By providing a clear, transparent and incorruptible method of vote recording and counting, voter fraud and election rigging could be eliminated. The political climate could be detoxified and faith could be restored in both fledgling and established democracies. The idea of being able to present a publicly available digital ledger would allow journalists to maintain lists of sources that would be able to be shared between peers without compromising the source’s identity. The possibilities for the application of the Blockchain founding principles are truly revolutionary and just may be the largest leap forward for society since the computerization of the work force or the globalization of trade. The Cryptocurrency Ecosystem Overstock is a large e-commerce company that has successfully adopted a Blockchain solution for its business needs. The Silk Road was one of the most widely known early beneficiaries of the mass adoption of cryptocurrencies. Purpose of Cryptocurrencies -Ethereum was developed after the original creator’s suggested changes to Bitcoin were not implemented by the community. -Ethereum is a completely separate cryptocurrency. -DAO Hack & the Ether Token. -Monero, Ripple, NEO, Stellar & Iota. -Microsoft has begun to accept Bitcoin on the Xbox live network store.
If there is a wide-scale expansion of the mechanism of asset-tokenization we could see stocks, bonds, synthetic instruments and commodities being brought on-chain in the future. This would allow traditional assets to be easily integrated with smart contracts, and facilitate their interaction. This would cut down transaction times, and even more importantly, dramatically slash legal fees to a fraction of what they are today. It can cost up to $1,000 an hour or more to hire corporate lawyers to preside over a deal, draft contracts, or give advice on the intricacies of high finance. So, the potential savings involved for big businesses, if smart contracts and asset tokenization became the norm, is an amazing thing to think about at this time. The ASX is the first exchange in the world to implement a solution that would change the settlement of equities transactions from two days, to mere minutes. This radically changes how traders on both the buy and sell side, as well as companies, would be able to trade their securities, manage their risk and leverage their positions.
