Avalanche Crippled by Bug Triggered by Unusually High Volume, Engineer Says

5 years 8 months ago

An Ava Labs engineer gave a rundown of the small code bug that severely crippled the Avalanche blockchain last week. 

In a Sunday Medium post, blockchain engineer Patrick O’Grady wrote that increased congestion on the network triggered a “non-deterministic bug” related to how the high-throughput, proof-of-stake blockchain keeps track of transactions. 

Funds were never at risk, O’Grady notes, though the high-profile misstep has a valuable lesson for the blockchain industry.

Avalanche launched in September 2020 with the claim it could process 4,500 transactions per second. It’s backed by prominent cryptocurrency firms including Mike Novogratz’s Galaxy Digital, Bitmain and Initialized Capital. It also has an academic stamp of approval, having been designed by Emin Gün Sirer, a computer science professor at Cornell University.

The blockchain is usually grouped with other so-called “Ethereum killers,” or blockchains designed to solve the scalability problems that have plagued the second-largest blockchain since inception. While positioned to steal market share from Ethereum, Avalanche also has been billed as a way to complement and connect – rather than strictly compete  – with its forbear. 

Avalanche has three “default chains,” including the so-called “contract chain” that supports the Ethereum Virtual Machine and its Solidity coding language. It’s this chain that was part of this week’s issue. 

You can read a full accounting of the problem that arose here. But in short, in order to boost transaction throughput, Avalanche’s three chains remain separate and distinct from each other, each performing within a set range of transaction-types, up until the moment an asset has to hop over to another chain. That process was placed under an incredible strain, following the launch of a new decentralized money market called Pangolin.

An atypical amount of users and volume created an atypical amount of blocks to be processed. This, O’Grady notes, triggered a bug that was creating false cross-chain “mints.” In O’Grady’s words: “This caused some validators to accept some invalid mint transactions, while the rest of the network refused to honor these transactions and stalled the [contract]-chain.”

Importantly, no double-spends occurred. “The bug did not affect regular transactions, coin transfers, asset transfers, coin destruction, or smart contract invocations. Avalanche never allowed any user to successfully send the same funds to two recipients,” O’Grady wrote.

A read of the issue was ready just hours after the initial issue, though a fix was harder to come by. Given Avalanche’s decentralized nature, it would be impossible to get all the nodes to collude and rollback problematic transactions. 

Instead, as O’Grady writes, a solution was found through incremental deployment of a patch – basically the way any software is updated. 

Blockchains are complex things, built by human beings, but run by machines. An issue that was small enough to bypass during an initial inspection can snowball as a network grows. In Avalanche’s case, the bug didn’t bring down the network but it did pour ice water over some of the boasts made about the network’s ability to handle high-throughput prior to launch.

AVAX, the blockchain’s token, is trading hands at around $41.20, down from $53 on Feb. 11 when the problem occured.

Coinbase Ventures, Paradigm Invest $12M in Synthetix DeFi Platform

5 years 8 months ago

Decentralized trading platform Synthetix has raised $12 million from venture capital firms Coinbase Ventures, Paradigm and IOSG. The raise looks to be a rare occurrence of VCs investing through the purchase of a platform’s native token directly from its treasury rather than wiring funds to its founders.

Synthetix is run by a DAO, or a decentralized automatic organization, a way for a project to govern itself without a traditional corporate structure. Token holders are typically encouraged to vote on the direction the DAO will take. 

In the case of Synthetix, a platform on which users can trade synthetic assets and commodities, including Brent Crude oil future, users can create these novel assets using the platform’s native synth token (SNX). The application has become a key component of decentralized finance (DeFi), with approximately $2.8 billion worth of crypto “locked.”

“We’re excited about supporting the synthetixDAO as it builds the leading synthetic asset platform,” Arjun Balaji, Paradigm investment partner, said in a press release. “Synthetix has one of the best communities in crypto and we’re glad to be a part of it.”

There is some debate about the role of venture capital in DeFi, with some commentators believing these firms could have a distorting effect on what are thought to be open, public protocols. This view came to a head this summer, with the rise of the self-stylized community-driven SushiSwap protocol, a fork of the VC-backed Uniswap.

Uniswap founder Hayden Adams spoke recently on the “mutually beneficial experience” between venture capital and DeFi denying claims that Uniswap’s backers were “extractive.”

In addition to providing liquidity for the protocol, the VCs will reportedly assist Synthetix recruit talent and plan for its next upgrade. Cointelegraph first reported the news.

SNX is down approximately 4% on the day and 10% from a local high, according to Messari.

Bitcoin Sets New All-Time High of $49.7K, Putting $50K Within Striking Distance

5 years 8 months ago

The price of bitcoin (BTC) rose Sunday morning to a new all-time high of $49,716 after a week of positive developments regarding increased Wall Street acceptance of the leading cryptocurrency.

  • Bitcoin hit a new high-water mark of $49,716.44, topping the previous mark of just over $49,000 set this past Thursday. At press time, BTC had pulled back, changing hands at $49,539, up 6.2% over 24 hours and 69% year-to-date.
  • While there doesn’t seem to be any specific reason for the move this morning, the record comes as traders analysts have described institutional investors’ interest in bitcoin as growing “at a staggering pace.”
  • Yesterday, there was further confirmation of that narrative when Bloomberg cited people familiar with the matter as saying Morgan Stanley’s $150 billion Counterpoint Global investment unit is exploring a stake in the cryptocurrency.
  • That news came shortly after it was revealed by CoinDesk that Deutsche Bank is planning to offer crypto custody to hedge funds that invest in the asset class, that Ark Investment Management boosted its exposure to BTC in the fourth quarter, and that BNY Mellon will roll out its own digital custody unit.
  • And all of this came days after the biggest news of the year for BTC, that electric carmaker Tesla has invested $1.5 billion in the cryptocurrency.
  • Other cryptocurrencies are also seeing big rises Sunday. LINK, the native cryptocurrency of oracle provider Chainlink, hit a new record high of $35.73 earlier this morning, while coins such as bitcoin cash, ethereum classic, bitcoin SV and NEO are all posting 24-hour gains of over 20%.

NBA Top Shot, CryptoKitties Firm Dapper Labs Raising $250M+ at $2B Valuation: Report

5 years 8 months ago

Dapper Labs, responsible for high-flying digital collectables such as NBA Top Shots and CryptoKitties, is raising funds that should net the firm more than $250 million at a valuation of about $2 billion, according to The Block, which cited sources familiar with the deal.

  • The funding round is being led by Coatue Management, which is led by billionaire investor Philippe Laffont, according to the report. Laffont has previously invested in Airtable, Instacart, Spotify, Bitmain and other well-known companies. 
  • The blockchain game developer has been on a roll, something the timing of the funding raise clearly reflects, The Block noted. Dapper Labs’ NBA Top Shop project is now the most popular non-fungible token (NFT) series by volume after being launched in October 2020.
  • The firm has generated almost $100 million in NFT sales, the report said.

Morgan Stanley Unit Considers Bitcoin Investment: Bloomberg

5 years 8 months ago

Morgan Stanley’s $150 billion Counterpoint Global investment unit is considering placing a bet on bitcoin, according to a report by Bloomberg, which cited people familiar with the matter.

  • In order to move ahead with an investment would need approval by the firm and regulators, Bloomberg noted.
  • If true, this investment would not be Morgan Stanley’s first exposure to the leading cryptocurrency. Already, it has a nearly 11% stake in the bitcoin-laden business intelligence company MicroStrategy, per CoinDesk’s reporting.
  • Analysts at Morgan Stanley say bitcoin has potential to strongly compete with the dollar, but acknowledge in a recent report that the more investors “hodl” bitcoin, the weaker its appeal to be used as a currency becomes.
  • A spokesperson from the investment bank declined to comment.
  • The investment unit manages nearly 20 funds, and Bloomberg reports five of those funds returned gains over 100% last year.

CORRECTION (Feb. 13 15:57 UTC): Corrects that the investment arm has $150 billion under management.

DeFi Protocols Cream Finance, Alpha Exploited in Flash Loan Attack; $37.5M Lost

5 years 8 months ago

Decentralized finance protocols (DeFi) Cream Finance and Alpha Finance were victims of one of the largest flash loan attacks ever Saturday morning resulting in a loss of funds totaling $37.5 million, according to transaction details on Etherscan.

Two hours later Cream said its contracts were “functioning as normal” and markets had been enabled.

Alpha Finance then posted its own announcement, saying its Alpha Homora V2 product as the root cause. They confirmed that they’re working with DeFi guru Andre Cronje and Cream Finance to investigate the incident, and that the loophole had been fixed. They also said that they “have a prime suspect” in mind.

 Earlier, Cream Finance tweeted an update on the incident saying that asset borrowing from its recently launched Iron Bank lending feature had been suspended. That tweet has since been deleted.

This is the second attack on a defi protocol in the last two weeks. Cronje’s Yearn Finance suffered an an exploit in one of its DAI lending pools, according to the decentralized finance (DeFi) protocol’s official Twitter account.  That exploit drained $11 million.

ConsenSys Grants Help Iranian Women Learn Solidity

5 years 8 months ago

Seven female coders from Iran got scholarships and graduated from a bootcamp of ConsenSys Academy, Ethereum startup incubator’s educational branch. 

The scholarships, a part of ConsenSys’ global program to help developers start coding on the Ethereum blockchain, might provide additional opportunities for people in the country largely cut off from the international tech community. 

Women account for 70% of university graduates in science, technology, engineering and mathematics (STEM) in Iran – more than in many developed countries around the world. But tech professionals in Iran are struggling with more roadblocks building their career than their peers in Europe and the U.S.

Related: Corporate Crypto Makes Government Bans Less Likely

Iran is subject to heavy international sanctions aimed at preventing the country’s leadership from developing nuclear weapons, and this impacts ordinary people’s ability to send and receive money from abroad. At the same time, Iran is a big contributor to the bitcoin network, providing around 4% of global hashpower. The country is a lucrative spot for miners and the blockchain community is active. 

Sahar Rahbari, an IT manager by training and a 38-year old mother of two, was one of the participants in the class of 2020. She first saw an announcement of the scholarships on Twitter, she told CoinDesk via direct messages on the platform. At the time she was working at a university in her town of Yasouj and maintaining her website for selling local agricultural produce. 

Rahbari became curious about blockchain tech after a friend asked her to translate an article about it. She then decided to study and work in the field. 

After finishing the course, Rahbari started freelancing for local blockchain projects, she said. She doesn’t currently see a lot of demand for such work in Iran, but there are only a handful of projects that would give her the experience she needs to try to get employed by an international company in the future, she added.

“In international projects, I know we can get crypto as a salary, and this is the most important thing in this field,” Rahbari said. “Because, as you know, we are in a strange and bad political condition in Iran. And even personally, I can’t have any financial transaction with other countries. But we can send and receive crypto in small amounts without any barriers. And this is one factor for me to choose this field.”

Stop signs

A training like the ConsenSys Academy offers could help Iranians learn new skills, perhaps increasing the chances for a Iranian dev to get a work visa and emigrate. This, unfortunately, is not enough to solve the geopolitical challenges that many ordinary Iranians face. 

U.S. and European companies are often reluctant to employ Iranian nationals or send money to locals due to concerns about potential sanctions violations. 

“Many work and study positions [abroad] (like system security) are banned for Iranians,” said Sanaz, another graduate of ConsenSys Academy’s 2020 class, who is now working toward her Ph.D. in IT at the University of Oslo, Norway.

“I have seen people being rejected [by companies in Europe] because there are some American contractors working with that European company,” Sanaz said, adding that she heard such stories from people she knows. She asked that her last name not be published.

Sanctions make even freelance work for Western companies difficult or impossible, said another alumna, software engineer Aysha Amin.

Coogan Brennan, head of developer relations at ConsenSys Academy, told CoinDesk that Iranian workers indeed experience more roadblocks when trying to build a global career. He noted that Iranian students were particularly strong in last year’s class.

But still, “you have to do a dance to suggest such candidates to companies. And being an Iranian is equivalent to a record scratch for some folks,” Brennan said via a call. 

Diplomatic mission

One hundred students around the world received grants last year from ConsenSys Academy, Brennan said. The class of 2020, which lasted from September through December, included both students who paid to learn blockchain skills and those who received grants via local NGOs, mostly in developing countries, and could attend online classes for free.

Students who got scholarships also included developers from Haiti, South Africa, Nigeria, the U.S., England and some other countries, Brennan said. There were $100,000 worth of grants this year, he said, and the program has been on for five years now. Brennan declined to name the overall amount of money spent on grants over five years.

Iranian students received $900 grants each, but not in a form of money. Rather, they were able to attend online courses and get mentorship for free. 

“We’re not actually giving money to them, we’re feeling like it’s more a diplomatic mission to give this opportunity to folks who need it,” Brennan said.

ConsenSys Academy chose the students with the help of the local blockchain organization CoinIran and ConsenSys’ Thessy Mehrain, who is half-Iranian. Alums are going to host an online forum in Farsi to help more Ethereum-curious developers in Iran with their work. 

“Hopefully, it could be a good start point for passionate developers in this field. And we want to extend the site to turn it to a place where developers can exchange knowledge, ask their questions and discuss their issues,” Sanaz said. 

For her, the new skills are a chance to get additional income, Sanaz said, but also a hope to “create systems that are unstoppable.”

Deutsche Bank Quietly Plans to Offer Crypto Custody, Prime Brokerage

5 years 8 months ago

Deutsche Bank has joined the growing ranks of large financial institutions exploring cryptocurrency custody, with aspirations to offer high-touch services to hedge funds that invest in the asset class.

The Deutsche Bank Digital Asset Custody prototype aims to develop “a fully integrated custody platform for institutional clients and their digital assets providing seamless connectivity to the broader cryptocurrency ecosystem,” according to a little-noticed report by the World Economic Forum, host of the annual gathering of muckety-mucks in Davos, Switzerland. 

In a passage buried on page 23 of the December 2020 report, Germany’s largest bank says it plans to create a trading and token issuance platform, bridging digital assets with traditional banking services, and managing the array of digital assets and fiat holdings in one easy-to-use platform.

Big banks are now announcing plans to enter crypto custody on an almost daily basis, with Bank of New York Mellon, the world’s largest custodian bank, joining the party earlier this week. 

U.S. banks were given some regulatory clarity thanks to last year’s interpretation letters from the Office of the Comptroller of the Currency. In Germany, firms are queuing up to get their hands on special crypto custody licenses from the country’s regulator, BaFIN. 

Deutsche, the world’s 21st largest bank, said it aims to “ensure the safety and accessibility of assets for clients by offering an institutional-grade hot/cold storage solution with insurance-grade protection.” No specific cryptocurrencies or tokens are mentioned.

The digital asset custody platform would be launched in stages. It would eventually provide clients with the ability to buy and sell digital assets via a partnership with prime brokers (which act sort of like concierges for hedge funds), issuers and vetted exchanges.

The bank says it would also provide “value-added services such as taxation, valuation services and fund administration, lending, staking and voting, and provide an open-banking platform to allow onboarding of third-party providers.” 

The service would be aimed at asset managers, wealth managers, family offices, corporates and digital funds, the bank said. 

In terms of a business model, the bank would start out collecting custody fees, it said, later charging fees for tokenization and trading.

Deutsche said it has completed a proof of concept and is aiming for a minimum viable product in 2021, while exploring global client interest for a pilot initiative.

The bank’s press office could not be reached for comment Friday evening. A spokesperson had declined to comment on potential plans for a digital asset custody business when contacted last week by CoinDesk.

5 Takeaways From Chia Network’s New White Paper

5 years 8 months ago

It will take 21 years for the rest of the world to mine as much of the Chia (XCH) cryptocurrency as the company behind it will have on the day its mainnet launches next month.

“We believe that chia, a new digital currency built on our new blockchain with radically different features and security than other digital currencies, will ultimately deliver on the promises of ‘magic internet money,'” the company argues in its first version of a new business white paper released on Wednesday.

The size of the pre-mine is one notable revelation from the paper, in which Chia also announced its mainnet will launch on March 17 or earlier. Farmers (the network’s equivalent of bitcoin miners) will be able to begin farming immediately. The network’s cache of pre-mined XCH, however, will be governed using a traditional format: Chia plans to take its company public.

Related: BNY Mellon Crypto Adoption Shows Consumer Appetite for Bitcoin

Chia was founded by Bram Cohen, the creator of BitTorrent, one of the most influential protocols on the internet. The company he founded was later sold to the Tron Foundation in 2018.

Chia first announced its intention to go public via the U.S. Securities and Exchange Commission’s so-called mini-IPO in 2018, but the decentralized web startup Blockstack won out as the pioneer there, raising $23 million under Regulation A+ in 2019. Last year, Chia raised a fresh round of $5 million in funding led by Slow Ventures.

Plans have shifted slightly since then, with the company now planning to, one way or another, take its offering to a national stock exchange where it can be traded by the public and the company will be subject to the same transparency as any publicly traded company.

One of Chia’s early backers was AngelList co-founder Naval Ravikant, who told CoinDesk in an email, “I backed Chia because I’ve known Bram for a long time and he is one of the greatest living protocol designers (BitTorrent), right up there with Satoshi and Vitalik.”

Related: Musk’s $1.5B Bitcoin Buy Sets the Tone for a Week of Corporate Adoptions

Chia has previously articulated its technical vision, a consensus model called Proof of Space and Time (PoST). This new paper articulates Chia’s vision for sustainability.

Chia’s president and COO, Gene Hoffman, told CoinDesk that the public should control more XCH than the company much earlier than 21 years and that the token is not the critical component of the consensus model anyway. 

“Unlike most projects, coin ownership has nothing to do with the protocol – this is not Proof of Stake,” Hoffman explained via email. “The chart of ownership percentages of coins in the Whitepaper is a worst case as we expect to use shareholder distribution to migrate XCH out to a broad public shareholder base.”

CoinDesk went through the new Chia white paper with a fine-tooth comb.

Here are five key takeaways from Chia’s new roadmap.

1. The blockchain is designed to make home mining feasible again

PoST relies on loading up unused computer storage space with strings of digits that farmers (what Chia calls blockchain validators) allow to be loaded on their computers. The more space, the more strings, the greater their chance of winning a block.

“It is super simple. Just download the Mac or Windows version and double click,” Hoffman told CoinDesk. “I’m pretty sure this will be the easiest cryptocurrency to validate for normal people ever.”

Other blockchains take a similar approach, such as Spacemesh. And Filecoin also seeks to capitalize on unused storage space.

In its testnet phases, Chia has reached as many as 1,700 nodes already, which is very likely to indicate something about interest in running a node when mainnet launches next month. Its public chat channel on Keybase has almost 4,000 people in it.

2. Chia favors predictable, continuous inflation over a hard cap

Bitcoin maxis fixate on the hard cap, but Chia argues that it’s not a fixed amount that matters so much as a predictable amount. Chia has no cap, but it’s also not going to surprise holders with unanticipated emissions.

“Being able to directly calculate a shared expectation of the total supply at any given time gives much the same financial and peace of mind benefit,” the white paper argues.

As noted, the company will start the mainnet with 21 million XCH, a nod to bitcoin, and farmers can start earning it right away. While it will take 21 years for the supply to double via farming, Hoffman knows that it will be very close in only six years. Then emissions will slow down considerably under the halving schedule.

By then, it’s likely that the company will have sold or airdropped a considerable amount of XCH.

3. Plans to embrace regulators, particularly by leading with a company that has public reporting requirements

“We have seen the scams and farces that have come before our project in this space and we will instead embrace the regulators,” the white paper states. “It should not be controversial that investors deserve protection through public disclosure and certainly the public shouldn’t be sold investments without that legally required transparency.”

By going with a public listing, Chia will essentially allow backers to treat its equity as an exchange-traded fund (ETF) for the XCH cryptocurrency. That’s because the company’s chief asset will be a considerable pre-mine (or pre-farm, in Chia lingo) of 21 million XCH that will be held for the company and is slated to be used for advancing the network.

“It’s owned by the company and subject to significant corporate controls that will only get more teeth as and when we go public,” Hoffman said. The provisions the company is committed to require it to only use its stash of XCH in ways that benefit XCH holders.

“We can use the pre-farm to raise capital that only dilutes the shareholders and not the farmers,” Hoffman noted.

4. The Chia blockchain has lots of native features that should make familiar crypto applications easier to trust and build

Chia comes with a number of features built in from the get-go that may increase trust and safety for users.

Here are a few described in the white paper that jumped out.

  • Clawback escrow: “Withdrawal clawback escrow adds a time period in which the sender can claw back the funds after the initial transfer moves onto the blockchain.”
  • Slow paper wallet: “Slow paper wallets allow you to store a smart transaction that’s capable of starting a time delayed process to recover your funds in your hot wallet but it is not a duplicate of your private key.”
  • Colored coins: Ethereum’s ERC-20 coins are what colored coins were back when they were still a concept. “Chia coloured coins can be used to create ephemeral value and thus applications on the Chia blockchain don’t generally require flash loans. This has been one of the achilles heels of DeFi on Ethereum.”

Flash loans have been the key to attacks on decentralized finance projects such as bZx, Harvest and Yearn Finance.

5. Chia is skeptical about proof-of-stake’s security against nation-states and other threats

“Their assumptions are inferior as they tend to cause centralization and are not as robust as Nakamoto consensus under international geopolitical pressure,” the white paper says of proof-of-stake (PoS) blockchains (after dismissing private, permissioned blockchains out of hand).

The problem with proof-of-work (PoW), Chia contends, is that it burns too much energy. Nevertheless, Chia also writes in the new white paper that its technology complements bitcoin, the largest PoW network.

But PoS, which Ethereum is moving toward, is another matter. Chia does not think the safety of this model is adequate. The white paper contends, “A considerable amount of effort is being expended attempting to solve what we believe are intractable problems with Proof of Stake as an alternate strategy to use less electricity securing public blockchains.”

It cites three key issues: centralization, where tokens tend to concentrate among a few giant holders; long-range attacks, where the history of the chain can be revised more easily than in PoW because there is no, well, work (to speak of) in PoS; and the inability of PoS networks to recover from a 51% attack.

It remains to be seen until there is real value on the line, but the hope is that PoST can lower the energy footprint of “magic internet money” without sacrificing the censorship resistance and decentralization that makes cryptocurrency so appealing to the cypherpunk-inclined and those dealing with unreliable nation-state currencies.

That’s the long term.

In the immediate term, Chia aims to scale what’s worked about crypto so far and build on it in a way that’s accessible for everyone. The white paper states:

“Someday we all might buy coffee in San Francisco with chia, but for now we think banks and governments and De-Fi collectives will use it to build new financial technology, solve cross border payments, and invent a new future that doesn’t require trusting so many middle men.”

ARK Invest Boosted Its GBTC Holdings by 2.14M Shares in Q4

5 years 8 months ago

Cathie Wood’s ARK Investment Management increased its holdings of the Grayscale Bitcoin Investment Trust (GBTC) by 2.14 million shares in the fourth quarter of 2020, bringing its holdings of the market-leading institutional bitcoin investment vehicle to 7.31 million shares.

  • ARK, the actively managed exchange-traded fund run by legendary manager and early bitcoin investor Cathie Wood, made the disclosure in a filing with the U.S. Securities and Exchange Commission.
  • At press time, ARK’s holdings of GBTC are worth $357.5 million.
  • ARK’s boosted stake is an increase from the 5.17 million GBTC shares it held on Oct. 31, 2020.
  • Not only did ARK’s holdings in GBTC rise in the fourth quarter, the value of GBTC shares took off as well, reflecting the meteoric rise in the price of bitcoin during that same time period.
  • GBTC shares rose 222% in the fourth quarter and are up 39% so far this year. The price of bitcoin increased 177% in Q4 and is up 63.1% YTD.

Market Wrap: Ether Sets New Highs as Bitcoin Stays Below $49K

5 years 8 months ago

The price of bitcoin struggled to regain $49,000 Friday, continuing to bounce between $48,000 and $46,000 heading into the weekend. As bitcoin contemplated which way to go, ether made a new all-time high above $1,850. 

  • Bitcoin (BTC) trading around $47,600 as of 21:00 UTC (4 p.m. ET). Slipping less than 1% over the previous 24 hours.
  • Bitcoin’s 24-hour range: $46,286 to $48,925

Much of bitcoin’s choppy price action could be attributed to futures deleveraging as eager bulls piled into long trades expecting a swift breakout to $50,000 or higher. Funding rates for perpetual bitcoin futures have steadily increased through February, according to market data collected by Skew, with some funding rates reaching their highest levels in the past 12 months.

High positive funding rates signal an increase in long positions, whereas negative rates indicate a more bearish sentiment. The market tends to reset when traders, especially in overcrowded derivatives positions, become overly bearish or bullish.

In the past 24 hours, over $330 million worth of bitcoin futures contracts were liquidated, according to market data from Bybt. Most of the liquidated positions were longs.

Despite the choppy price action, news over the past few days has been extraordinarily bullish for the leading cryptocurrency. In one week, Tesla bought $1.5 billion worth of bitcoin, Twitter’s CFO said the company is considering investing in the cryptocurrency, BNY Mellon announced plans to custody bitcoin for its clients, and PayPal confirmed its plans to add crypto to its Venmo product.

As it set new record highs above $1,850, other decentralized finance-related (DeFi) cryptocurrencies followed suit, with some even outperforming ether. The DeFi sector in aggregate rallied over 5% in the past 24 hours, according to Messari, led by Uniswap, yearn.finance and others, which gained by double-digit percentages.

Ether’s fresh highs come the same week the CME launched its ether futures market, which some traders anticipated would be a bearish catalyst for the market. The expectations were almost exclusively pinned to the ominous timing of bitcoin’s peak in 2017 near the launch of CME’s bitcoin futures market. Yet, so far the bearish thesis has not played out. 

Since CME’s futures launch, ether has rallied over 12%. The product has had a quiet start, with less than $200 million worth of contracts traded this week. In contrast, Binance’s ether futures have traded nearly $40 billion worth this week.

MicroStrategy Begins Hiring for Bitcoin Data Product

5 years 8 months ago

MicroStrategy is moving to assemble a blockchain analytics team. It would be the first bitcoin-related software product from a company best known for CEO Michael Saylor’s whopping bet on BTC as a reserve asset.

The firm, based in Tysons Corner, Va., put out calls on LinkedIn Friday for a Blockchain Data Analyst and Blockchain Data Engineer, explaining in job postings they will join a team “building an analytics platform with advanced metrics and insights for Bitcoin.”

MicroStrategy hinted last November its interest in building blockchain data products and even stated its intention to hire for them. Executives did not go public then with positions of interest and remained largely mum on program specifics, describing it as a potential data offering at the time.

But Saylor has been vocal about perceived deficiencies in bitcoin‘s data. He declared last October that “garbage” market data was holding bitcoin back. “Where can you find something so incredibly compelling that has such bad data around it relative to other assets?” Saylor said at the time. 

For a man who spent much of last week all but pleading for his fellow CEOs to adopt the bitcoin standard, there’s an obvious, and vested, interest in improving upon the “garbage.”

MicroStrategy did not respond to a request for comment by press time.

The dual hirings add a rough picture to what could eventually become a commercialized intelligence offering for digital assets beyond just bitcoin. MicroStrategy wants analysts experienced with public, private and permission blockchains. (Bitcoin’s network is public and permissionless.)

A product would also produce shareable, digestible analytical insights, the listings indicate. MicroStrategy’s new engineer would be responsible for developing software capable of turning troves of data into “visualizations” that can be shared with “broader audiences.”

The job postings position MicroStrategy to capitalize on bitcoin Saylormania through the software intelligence space, which, as is so easy to forget for a company with 71,079 BTC on its balance sheet, is the firm’s longstanding business expertise.

Ethereum 2.0 Deposit Contract Tops $5.5B in Staked Ether

5 years 8 months ago

The deposit contract for the Ethereum 2.0 Beacon Chain – the epicenter of Ethereum’s new architecture – now holds over 3,000,000 ETH, worth over $5.5 billion at current prices.

  • Per data from Etherescan, there are some 3,062,210 ETH locked in the contract.
  • The contract launched at the beginning of November and within three weeks it had secured the necessary threshold of ETH to lock in the Beacon Chain’s launch, which took place in the first week of December.
  • The Beacon Chain is a bridge network between the current Ethereum network and Ethereum 2.0; when the time comes, the Beacon Chain will help “dock” the current mainnet onto 2.0 to ensure the network’s complete migration.
  • Unlike the current Ethereum blockchain, Ethereum 2.0 uses proof-of-stake where “validators” replace miners to process transactions.
  • To earn the title of validator, an Ethereum user must stake 32 ETH into the deposit contract through a validator node.
  • Exchanges like Kraken and Coinbase and wallets like MyEtherWallet also facilitate custodial staking for their clients by running a validator node on their behalf. Coinbase (whose staking is forthcoming) and Kraken allow users to stake any amount, not just the 32 ETH required by Ethereum 2.0’s rules.

Blockchain Bites: Canada Approves Bitcoin ETF, Options Markets Not Pricing for $100K BTC

Editor’s Note: Welcome to the year of the Ox. Blockchain Bites will not publish on President’s Day, Monday, Feb. 15.

Three stories Bull market buzz

The first bitcoin exchange-traded fund in North America has been approved by Canada’s securities regulator, a move some commenters see as opening the door for the U.S. to follow. The U.S. government has been hesitant to approve a bitcoin ETF product, which tracks the price of bitcoin and is traded on a stock exchange, due to bitcoin’s supposedly shallow liquidity and risks the asset could be manipulated.

Bitcoin miners earned a record $4.06 million in just 60 minutes yesterday, according to Glassnode data. The majority of those proceeds came from the bitcoin subsidy – 6.25 BTC issued roughly every 10 minutes – though some $47,000 was collected in network fees.

Bitcoin options market sees a 12% probability of prices rising above $100,000 by the end of December, according to a mathematical metric called the Black Scholes formula. It looks at strike prices, call option prices, the actual asset and U.S. Treasurys to determine the fair price of an option’s contract.

Everybody wants in?

PayPal CEO Dan Schulman said the payments giant is looking to become a CBDC distributor, if a central bank digital currency ever launches. “You think about how many [digital wallets] we’re going to have in the next two, three or five years, and we’re a perfect complement to central banks and governments to distribute those digitized forms of currency,” Schulman said at the company’s investor day.

Wall Street suits are pressuring their employers to move into crypto, according to CNBC. In response to internal questions, JPMorgan Chase co-President Daniel Pinto reportedly said the bank would consider bitcoin trading if customer demand was “there,” which “I’m sure it will be at some point.”

Miami Mayor Francis Suarez has floated everything from a bitcoin city treasury to paying employees in the crypto. Yesterday, however, city commissioners tapped the brakes on these ambitious plans to study their impact first. Commissioners did vote to launch education campaigns in English, Spanish and Creole to inform people about crypto.

Around the world

Nigeria’s Securities and Exchange Commission (SEC) announced Thursday it has put plans to regulate cryptocurrencies on hold in light of the central bank’s decision to ban them, according to a report by the Guardian Nigeria. This follows a meeting yesterday where Nigeria’s Senate summoned the country’s top financial regulators to speak about the bill, which had received public pushback.

India will give crypto holders a three-to-six month window to cash out, if a proposed ban on cryptocurrency goes through. The Cryptocurrency and Regulation of Official Digital Currency Bill, floated this year, seeks to limit private currencies in the country and set up a framework for a national digital currency.

Twitter CEO Jack Dorsey announced Friday that he will partner with rapper Jay-Z and donate 500 bitcoin (~$23.6 million) to set up a new endowment trust supporting Africa and India. Separately, Dorsey donated $1 million to cryptocurrency policy think tank Coin Center, announced Wednesday.

Popping bubbles?
Former CFTC Chairman Christopher Giancarlo cleared the record on the commodity regulator’s role in popping the 2017 bitcoin bull market this morning on CoinDesk TV.

CoinDesk previously reported that the Trump administration acted to puncture the 2017 bubble by clearing the way for futures products. 

“We saw a bubble building and we thought the best way to address it was to allow the market to interact with it,” Giancarlo said in late 2019. He said the launch of bitcoin futures “would have the impact of popping the bitcoin bubble. And it worked.”

These comments have led to a conspiracy that U.S. regulators are antagonistic to the growth of the cryptocurrency industry. Similar questions arised earlier this week, after the Chicago Mercantile Exchange launched the nation’s first regulated ether (ETH) futures. 

Giancarlo tempered these fears this morning. Adding that security and commodity regulators don’t have the authority, nor the ability, to have such a heavy hand in capital markets. 

The story is slightly more complicated. Derivatives, Giancarlo, argued are an essential part of any mature market. 

“The ability to short a market is an essential maturatization point in the development of any market,” he said, adding that the in most modern market asset prices are not set in spot markets, but in a higher order financial level. “The institutional role in bitcoin has made it into a truly investment grade asset.”

To the extent that bitcoin futures did deflate the bubble, it was just a matter of good old capitalist price finding. 

“[Derivatives] brought the price of bitcoin back in correlation to its fundamental cost of production,” Giancarlo said. “In 2017, bitcoin had broken away from those fundamentals.”

So what does Giancarlo think about today’s frothy markets? He didn’t address the question directly, but we can again turn to the market itself. 

As CoinDesk markets reporter Omkar Godbole noted, derivative traders see a low probability of the market to inflate past six figures by the end of the year. 

“With the extreme volatility of the past two months, the market isn’t showing a lot of conviction on how bitcoin will trade for the rest of the year,” Sui Chung, CEO of CF Benchmarks, told Godbole.

BlockFi Boosted Grayscale Bitcoin Trust Holdings by 11.9M Shares, Now Holds $1.7B GBTC

5 years 8 months ago

Crypto lender BlockFi on Friday revealed it holds $1.7 billion in shares of the Grayscale Bitcoin Trust, or 5.66% of the market-leading institutional bitcoin investment vehicle.

  • The 36.1 million GBTC shares now held by BlockFi represents an 11.9 million increase from its previous holdings of 24.2 million shares, first disclosed last October.
  • BlockFi CEO Zachary Prince previously told CoinDesk the GBTC holdings “add value” to the “marketplace for liquid and illiquid” shares. “There are lending markets related to GBTC,” he said at the time.
  • BlockFi’s ongoing stake in GBTC is particularly notable due to BlockFi’s intentions to launch a bitcoin trust product that directly competes for institutional dollars that might otherwise flow into GBTC.
  • Grayscale is owned by CoinDesk parent company Digital Currency Group.

Ex-CFTC Chair Christopher Giancarlo Stumps for Digital Dollar

5 years 8 months ago

Former CFTC chairman J. Christopher Giancarlo laid out his case for state-issued digital currencies on CoinDesk TV’s “First Mover” program Friday morning.

  • Speaking as G7 leaders were set to meet with central bank digital currencies (CBDC) on their agenda, the regulator sometimes known as “crypto dad” pushed for a U.S. digital dollar that strikes a balance between privacy rights and society’s best interests.
  • He also waxed prophetic on the potential reach of China’s digital yuan project, saying that while he is not an alarmist on the world’s fastest-developing CBDC, governments must remain mindful of its reach.
  • “A digital yuan would present the opportunity to basically bypass the global bank based system and arrange for direct payments, and therefore our ability to use sanctions would be diminished,” he said.

Former Bitcoin Developer Mike Hearn Steps Down From Enterprise Blockchain Firm R3

5 years 8 months ago

Mike Hearn, the lead platform engineer at enterprise blockchain builder R3, is stepping down from his role at the company, CoinDesk has learned.

Hearn will stay on at R3, but only in the capacity of a technical adviser, according to a memo sent to company staff Friday. 

Hearn has long harbored ambitions to broaden his range and start new projects, the memo said.

“Mike’s plans include his own projects, as well as becoming technical advisor to the R3 executive committee. To support the former, he’ll become CEO of his new firm, as well as transitioning to his ongoing R3 advisory role,” it said.

Hearn, who joined R3 in 2015, was instrumental in the creation of the Corda platform with CTO Richard G. Brown. Most recently, Hearn oversaw the recently rolled out Conclave system built using Intel’s SGX technology.

Before joining R3, Hearn was one of leading early developers building Bitcoin’s core software, and he is one of the few people to have had email conversations with bitcoin’s pseudonymous creator, Satoshi Nakamoto. He quit the project in a very public way in early 2016. Prior to that, he was a senior software engineer and tech lead at Google. 

Hearn did not immediately return requests as to whether he might be rejoining the bitcoin ecosystem, or more broadly, the world of public blockchains.

Enterprise blockchain, once the battle cry of large corporates, seems to be firmly in the trough of disillusionment these days, with clear evidence of atrophy at R3 rival IBM, where former staffers and other insiders said the primary blockchain team had all but been dissolved.
