Bad Ravencoin Code Allows Attackers to Generate Coins Without Mining

Unidentified attackers exploited a Ravencoin vulnerability to mint extra RVN “beyond the coinbase of 5000 RVN per block,” Ravencoin lead developer Tron Black wrote in a Medium post on Thursday.

According to Black, members of Ravencoin’s CryptoScope team, who developed Solus Explorer, reached out to the Ravencoin developer team recently with their findings. 

The vulnerability was caused by a community code submission. “Law enforcement has been notified and is working with us,” Black said. 

The extra coins increase the total supply of 21 billion RVN by 1.5% or the equivalent of 44 days worth of mining.

Ravencoin is an open-source fork of bitcoin that launched in 2018. It’s designed to facilitate the transfer of assets from one party to another, and users can create assets on the protocol that adhere to rules independent of those on the platform. The project’s website specifically calls out the Game of Thrones’ reference to Ravens as messengers of truth, which parallels the concept of blockchains as a technology for ultimate truth. 

Black suggested the Ravencoin community either absorb the economic cost of extra RVN or shift the halving of the coins 44 days sooner. Black did not return a request for comment by press time.

“The vulnerability does not allow the stealing of RVN or assets that you own and control, but the minting did create RVN that should not exist,” Black said. “Because those RVN were transferred to an exchange and traded, they are mixed with other RVN and therefore any programmatic attempt at burning them, with miner and community backing, would cause irreparable harm to innocent victims. As it stands, the burden has been shared across all RVN holders in proportion to their RVN holdings in the form of inflation.”

Black urged users to keep trading to a minimum until a fix is issued. He also said that Ravencoin would not publish the details of the vulnerability until the fix could be implemented. As of yet, there is no timeline for when the chain will be updated.

Former US Treasury Secretary Larry Summers Expects ‘A Ton of Innovation’ Around Stablecoins

Former U.S. Treasury Secretary Lawrence Summers praised stablecoins, but said he would be surprised if a global digital currency became a reality in his lifetime.

During a special episode of Circle co-founder and CEO Jeremy Allaire’s podcast, “The Money Movement” last week, Summers said he foresees more innovation in the blockchain space but a global digital currency is still at a nascent stage. The comments came as part of a broader discussion on the current state of the global economy, the future of a global digital currency and the role of stablecoins in cross-border transactions.

“I’m sure there’ll be a variety of kinds of innovation, but I’d be kind of surprised, and, you know, I’ve been surprised many times before, if we got to some kind of global digital currency … in my lifetime,” he said. “I could be wrong, I think … we’ll see a ton of innovation that will work through stablecoins, and that will permit cross-border exchange with more with more ease.”

In Summers’ view, the case for cryptocurrency rests on three pillars, but two fail to make strong arguments in favor of the technology. 

For one, it is unlikely that governments around the world will debauch traditional currencies to the point where people will no longer want to put money in them. He said he doesn’t “read existing currencies as being on their way to being demolished” just because central banks are finding it difficult to meet their inflation targets, under pressure from rising debts and the crisis caused by the pandemic. 

“Second thing I think is that I don’t think crypto is going to be accepted as some kind of libertarian paradise,” Summers said. 

Summers doesn’t think that there are people who believe that financial privacy, in terms of the ability to transfer money, is a fundamental human right. Conversely, governments will want less financial privacy over time and they will get what they want, he said. 

The strongest case for crypto is that digital currencies have a substantial capability to serve a wide range of uses, particularly because traditional transactions are cumbersome and cost a lot of money, Summers said. The hefty fees for cross-border transfers or the fees involved in card payments and ATM withdrawals reveal the excessive friction and inefficiencies of the current payments system. Stablecoins in particular can permit cross-border exchange with more ease, he said.  


Just a week after Summers’ remarks, the dollar-pegged cryptocurrency issued by the CENTRE Consortium, USDC, crossed $1 billion in market capitalization.

The stablecoin backed by U.S. dollars held by CENTRE, which in turn was created by Circle and Coinbase, achieved the milestone less than two years after launching, though it trails the Tether stablecoin by some $8 billion, Circle announced Thursday.

Demand for stablecoins has grown, Circle said. It does not appear, however, that this growth was influenced by Summers’ comments.

In CENTRE’s announcement Thursday, the growth of global stablecoins was attributed to currency volatility caused by the current financial crisis and a rising demand for “digital dollars that are fast, global, secure, and inexpensive”.

“Secondly, businesses around the world are beginning to seek the advantages of payments made via an entirely new, digital, global and interoperable infrastructure that enables low-cost transfers anywhere nearly instantly,” the announcement said. 

Digital yuan

During last week’s discussion, Allaire said stablecoins can pose a threat to governments because it can potentially be “accessed with any digital wallet on any smartphone by anyone, anywhere.”

In the same discussion, Allaire said he believes the push for a digital yuan reflects China’s desire to play an even greater role in the world economy. There is also a desire to have a financial system that’s not controlled by the West or the Brussels-based global financial messaging system SWIFT, he said.

“With the development of the Chinese digital currency, effectively, they’ve created a model where a household, a firm, a nation state can kind of directly transact and settle with China over the internet and you don’t need SWIFT, you don’t need any of the regulations that control that. You can just bilaterally, over the internet, start to achieve that,” Allaire said. 

Secretary Summers agreed, saying China wants to control the lives of their citizens, including their financial lives. In his view, a system that lets citizens freely move wealth and resources out of a country is going to be a system that makes the government “deeply nervous”. 

“And I think a system that is so restricted that it isn’t possible to do that isn’t going to be much of a global digital currency,” he said.

Search For Yield Drives Ether’s Put-Call Ratio to One-Year High

Investors’ search for yield has pushed a widely tracked ether options market metric to its highest level in 12 months. 

The put-call open interest ratio, which measures the number of put options open relative to call options, rose to 1.04 on Thursday, a level last seen in July 2019, according to data provider Skew, a crypto derivatives research firm. 

A put option gives the holder the right but not the obligation to sell the underlying asset at a predetermined price on or before a specific date. Meanwhile, a call option represents a right to buy.  Open interest refers to the number of contracts open at a specific time.

The metric has nearly tripled in value over the last 3.5 months and has witnessed a near 90-degree rise from 0.84 to 1.04 in the last two weeks. 

“Typically this implies the market is more bearish as investors are buying puts to protect their portfolios from a fall in the underlying,” said Luuk Strijers, COO at cryptocurrency exchange Deribit, the biggest crypto options exchange by trading volumes. 

Ether, the second-largest cryptocurrency by market value, is flashing signs of uptrend exhaustion. Prices have failed multiple times in the last few weeks to keep gains above $240. As such, some investors may have bought puts. 

However, in this case, the put-call open interest ratio has risen mainly due to increased selling in the put options. “In this case, market makers have long options positions while the clients are net sellers of puts,” said Strijers told CoinDesk, and added that, “clients, in this case, are generating additional yields using their ETH holdings.”

Traders sell (or write) put options when the market is expected to consolidate or rally. A seller receives a premium (option price) for selling insurance against the downside move. If the market remains comatose or rallies, the value of the put option sold drops, yielding a profit for the seller. 

It’s quite likely that investors holding long positions in the spot market are writing put options to generate extra yield, given the market sentiment is bullish. 

“There’s a lot of excitement around new DeFi tokens and most of the collateral locked up across those platforms is in Ethereum. As that outstanding ether supply comes down and demand from Defi platforms hits escape velocity, ether will rally hard,” tweeted John Todaro, head of research at TradeBlock. 

Validating Strijers’ argument are negative readings on three-month and six-month skews, a sign call options are costlier than puts. Skew measures the price of puts relative to that of calls.

Three and six-month skews would have been positive had investors been buying put options. 

One-month skew, too, was hovering at -4% on Thursday. While it has bounced up to 4.7% on Friday, the metric still remains well below highs around 10% seen on June 28. 

Volatility metrics also suggest that the market in general is dominated by option writers. “There seem to be more sellers in the market which is also visible in especially the shorter-dated implied volatility dropping to lowest levels since more than 1 year,” said Strijers.

Ether’s one-month implied volatility or investors’ expectations of how volatile or risky ether would be over the next four weeks is seen at 47% at press time, the lowest since Skew began tracking data in April 2019. 

Option implied volatilities are driven by the net buying pressure for options and historical volatility. Stronger the buying pressure, greater is the implied volatility.

Russian Courts Can’t Agree on Whether Crypto Is Property

Russian courts are making conflicting rulings on whether bitcoin and other cryptocurrencies count as property.

In one new case, Saint Petersburg’s district court has refused to force bogus law enforcement officers to return cryptocurrencies extorted from a victim on the basis that digital assets are not legitimate assets.

According to the press office Telegram channel for the Saint Petersburg courts, the district court convicted two men for extorting money from an unnamed cryptocurrency OTC trader on June 30. 

The criminals had pretended to be officers of Russia’s law enforcement and counter-terrorism agency, the Federal Security Service (FSB) – the successor of the KGB.

Threatening to beat and torture the victim, as well as faking that they’d opened a felony case against him, Petr Piron and Eugeny Prigozhin forced the victim to pay them 5 million rubles (over $70,000) in cash and transfer 99.7035 in bitcoin and some DigiByte and BitShares tokens to their digital wallets. The bitcoin alone is worth over $900,000 at current prices.

According to the court press release, the victim has been handed back the cash that was stolen. However, the court did not rule that the cryptocurrencies should also be transferred back. The court’s website confirms the convictions, although it does not provide the text of the ruling. 

The press release, however, points out that, under the Russian Civil Code, cryptocurrencies have no legal status and therefore cannot be deemed property for the purpose of a criminal case.

Plain wrong?

The decision is nothing more than a mistake, believes crypto-savvy lawyer and deputy head of the Chamber of Tax Consultants in Russia, Mikhail Uspenskiy. “The stance that cryptocurrency is some kind of a dummy and has no legal significance, is deeply flawed and erroneous,” Uspenskiy told CoinDesk. 

He pointed out that, previously, the Russian courts have recognized crypto as a form of property. Uspenskiy cited the case of Ilya Tsarkov, who filed for bankruptcy in 2017 and was forced to reveal his crypto holdings so that they can be included in his estate for bankruptcy proceedings. 

There have been also criminal cases in which the courts treated crypto assets like a form of property, such as when bitcoin was extorted during blackmail or fake banknotes exchanged for crypto, Uspenskiy said. 

And in another case, after a Russian court refused to recognize crypto losses claimed by ICO investors who used an online investment platform called, a Moscow court of appeals backed the original ruling, but did define cryptocurrency as “other kind of property.”

The appeals court further said that, under Russian law, crypto is not defined either as property, an asset, a money surrogate or information.

That may soon change. In June, a package of draft bills was introduced in the country’s parliament, the State Duma, suggesting that cryptocurrencies should be treated as property. The bills would also, however, prohibit any operations with crypto using Russia-based infrastructure.

The initiative has been criticized by Russia’s Mininstry of Economic Development and Ministry of Justice, as well as by the crypto community advocates in the country.

Money Reimagined: Bitcoin and Ethereum Are a DeFi Double Act

Tensions between the Bitcoin and Ethereum tribes have been stirred by a trend that outsiders might see as a sign of harmony. 

Throughout June, the amount of tokenized bitcoin on Ethereum, the bulk of it in WBTC, a special ERC2 token known as “wrapped bitcoin,” soared from 5,200 BTC to 11,682 BTC – now worth around $108 million – according to

As is their wont, each faction described the growth of WBTC tokens, whose value is pegged one-to-one against a locked-up reserve of actual bitcoin, as proof of their coin’s superiority over the other. The Ethereum crowd said it showed that even BTC “hodlers” believe Ethereum-based applications provide a better off-chain transaction experience than platforms built on Bitcoin, such as Lightning or Blockstream’s Liquid. Bitcoiners, by contrast, took it as confirmation that people place greater value in the oldest, most valuable crypto asset, than in Ethereum’s ether token.

Beneath the rivalry on Crypto Twitter, the bitcoin-on-Ethereum trend says more about complementarity than competition. 

The data simultaneously highlight that bitcoin is the crypto universe’s reserve asset and that Ethereum’s burgeoning “DeFi” ecosystem is crypto’s go-to platform for generating credit and facilitating fluid exchange. 

Real world parallels

Though it’s too early to know who the eventual winners will be, I believe this trend captures the early beginnings of a new, decentralized global financial system. So, to describe it, an analogy for the existing one is useful: bitcoin is the dollar, and Ethereum is SWIFT, the international network that coordinates cross-border payments among banks. (Since Ethereum is trying to do much more than payments, we could also cite a number of other organizations in this analogy, such as the International Swaps and Derivatives Association (ISDA) or the Depository Trust and Clearing Corporation (DTCC).) 

So, let’s dismiss claims like those of co-founder Anthony Sassano. He argued that because bitcoin token transactions on Ethereum deny miners fees they would otherwise receive on the bitcoin chain, bitcoin is becoming a “second-class citizen” to ether. You’d hardly expect people in countries where dollars are preferred to the local currency to think of the former as second class. And just as the U.S. benefits from overseas demand for dollars – via seignorage or interest-free loans – bitcoin holders benefit from its sought-after liquidity and collateral value in the Ethereum ecosystem, where it lets them extract premium interest. 

Still, to declare bitcoin the winner based on its appeal as a reserve asset is to compare apples to oranges. Ether is increasingly viewed not as a payment or store-of-value currency but for what it was intended: as a commodity that fuels the decentralized computing network orchestrating its smart contracts. 

That network now sustains its financial system, a decentralized microcosm of the massive traditional one. It takes tokenized versions of the underlying currencies that users most value (whether bitcoin or fiat) and provides disintermediated mechanisms for lending or borrowing them or for creating decentralized derivative or insurance contracts. What’s emerging, albeit in a form too volatile for traditional institutions, is a multifaceted, market for managing and trading in risk.  

This system is being fueled by a global innovation and development pool bigger than Bitcoin’s. As of June last year, there were 1,243 full-time developers working on Ethereum compared with 319 working on Bitcoin Core, according to a report by Electric Capital. While that work is spread across multiple projects, the size of its community gives Ethereum the advantage of network effects.

Whether DeFi can shed its Wild West feel and mature sufficiently for mainstream adoption, the code and ideas generated by these engineers are laying the foundation for whatever regulated or unregulated blockchain-based finance models emerge in the future. 

Complexity vs simplicity

There are legitimate concerns about security on Ethereum. With such a complex system, and so many different programs running on it, the attack surface is large. And given the challenges the community faces in migrating to Ethereum 2.0, including a new proof-of-stake consensus mechanism and a sharding solution for scaling transactions, it’s still not assured it will ever be ready for prime time. 

Indeed, the relative lack of complexity is one reason why many feel more comfortable with Bitcoin Core’s security. Bitcoin is a one-trick pony, but it does that trick – keeping track of unspent transaction outputs, or UTXOs – very well and very securely. Its proven security is a key reason why bitcoin is crypto’s reserve asset. 

Base-layer security is also why some developers are building “Layer 2” smart contract protocols on Bitcoin. It’s harder to build on than Ethereum, but solutions are evolving – one from Rootstock, for example, and more recently, from RGB

And while Ethereum fans crow about there being 12 times more wrapped bitcoin on their platform than the mere $9 million locked in the Lightning Network’s payment channels, the latter is making inroads in developing nations as a payment network for small, low-cost bitcoin transactions. Unlike WBTC, which requires a professional custodian to hold the original locked bitcoin, Lightning users need not rely on a third party to open up a channel. It’s arguably more decentralized. 

Toward anti-fragility

At the same time, the inclusion of bitcoin in Ethereum smart contracts is inherently strengthening the DeFi system. 

Decentralized exchanges (DEXs), which allow peer-to-peer crypto trading without centralized exchange (CEX) taking custody of your assets, have integrated WBTC into their markets to boost the liquidity needed to make them viable. Sure enough, DEX trading volumes leapt 70% to record highs in June. (It helped, too, that June saw a surge in “yield farming” operations, a complicated new DeFi speculative activity that’s easier to do if you maintain control of your assets while trading.)   

MakerDAO team image (Twitter)

Meanwhile, the recent move by leading DeFi platform MakerDAO to include WBTC in its accepted collateral has meant it has a bigger pool of value to generate loans against. 

This expansion in DeFi’s user base and market offerings is in itself a boost to security. That’s not just because more developers means more code vulnerabilities are discovered and fixed. It’s because the combinations of investors’ short and long positions, and of insurance and derivative products, will ultimately get closer to Nassim Taleb’s ideal of an “antifragile” system.

That’s not to say there aren’t risks in DeFi. Many are worried that the frenzy around speculative activities such as “yield farming” and interconnected leverage could set off a systemic crisis. If that happens, maybe Bitcoin can offer an alternative, more stable architecture for it. Either way, ideas to improve DeFi are coming all the time – whether for better system-wide data or for a more trustworthy legal framework. Out of this hurly burly, something transformative will emerge. Whether it’s dominated by Ethereum or spread across different blockchains, the end result will show more cross-protocol synergy than the chains’ warring communities would suggest.

Gold “To The Moon”

Bitcoin might be a reserve asset for the crypto community but its recent price trajectory, with gains and losses tracking equities, suggest the non-crypto “normies” don’t (yet) see it that way. Given the COVID-19 crisis’s extreme test of the global financial system and central banks’ massive “quantitative easing” response to it, that price performance poses a challenge to those of us who see bitcoin’s core use case as an internet era hedge against centralized monetary instability. Far from complying with that “digital gold” narrative, bitcoin has performed like any other “risk-off” asset. Meanwhile, actual gold has shaken off its own early-crisis stock market correlation to chart an upward course. While bitcoin has repeatedly failed to sustainably break through $10,000, bullion has rallied sharply to close in on $1,800, levels it hasn’t seen since September 2012. Some analysts are predicting it will breach its all-time intraday high of $1,917, hit in the aftermath of the last global financial crisis in 2011. To add insult to injury, one Forbes contributor even stole from the crypto lexicon to describe the state of play, telling his readers that gold prices are “soaring to the moon.”

Two charts below show the divergent fortunes of these two would-be safe havens. Throughout 2019, bitcoin seems far less correlated with the S&P 500 stock index than gold is. Come the collapse in March 2020, they seem to swap circumstances.

S&P and gold over time (CoinDesk)

How to reconcile this? Time. 

Gold has had at least three millennia to establish itself as a store of value people turn to when social systems are in stress. Bitcoin has only existed for 11 years and while plenty of investors are willing to speculate on the possibility that it might supplant or compete with gold, the idea is far from ingrained across society. When will it be more widely accepted? Perhaps when the international crisis of global leadership unleashed by COVID-19 undermines the capacity of institutions like the Federal Reserve to sustain economic and social confidence. Whatever new institutions and systems we create going forward will need to address how the internet has upended society’s centralized systems of governance. When that happens, we’ll need a decentralized, digital reserve asset as the base value layer. As I said, it will take time. Meanwhile, the developers will keep building.

Global Town Hall

TRUST ME, BOND MARKET, PLEASE. James Glynn at The Wall Street Journal had a piece this week about how the Federal Reserve is considering following Australia’s lead in using “yield caps” as a policy tool to keep long-dated interest rates down. The thinking is that if the central bank explicitly signals it will always institute bond-buying if the yield on a benchmark asset such as the 10-year Treasury note rises above some predefined ceiling, the market will be less inclined to prematurely believe the Fed is going to start tightening monetary policy. In other words, we won’t see a rerun of the 2013 “Taper Tantrum,” when the U.S. bond market, worrying that the Fed would start tapering off its bond-buying, or quantitative easing, drove down bond prices, which pushed up yields. (For bond market newbies, yields, which measure the effective annual return bondholders will earn off a bond’s fixed interest rate when adjusted for its price, move inversely to price.) 

The yield cap policy would be new for the Fed, but it’s really an extension of an ongoing effort to do one thing: get the market to believe its intentions. The way monetary policy works these days, it’s meaningless unless the market behaves according to what the Fed wants. It’s not about what the central bank does per se; it’s about what it says and whether those words are incorporated into investor behavior. But the more it doubles down on this, the more the Fed creates situations in which it risks having its words held against it. And that puts it at risk of losing its most important currency: the public’s trust. Commitments to price targets are always especially risky – ask Norman Lamont, the UK Chancellor of the Exchequer, who had to abandon the pound’s currency peg in 1993 because the market didn’t believe the U.K. would back its promises. The Fed has unlimited power to buy bonds, but whether it always has the will to do so will depend on politics and other factors. Once it’s locked into a commitment, the stakes go up. For now, the markets – most importantly, foreign exchange markets – still trust the Fed. But, as the saying goes, trust is hard to earn, easy to lose.

ZIMBABWE ACCIDENTALLY LEAVES DOOR OPEN FOR CRYPTO. Here’s a recipe for  creating a fertile environment for alternative payment systems: outlaw the system that everyone is currently using. When the Zimbabwean government made the nutty step of banning digital payments – used for 85% of transactions by individuals, due to severe shortage of cash – it clearly wasn’t trying to promote bitcoin. In forcing people to go to a local bank to redeem funds locked in popular payments apps such as Ecocash, its goal was to protect the embattled Zimbabwean dollar. In a statement, the Reserve Bank of Zimbabwe, said the move was “necessitated by the need to protect consumers on mobile money platforms which have been abused by unscrupulous and unpatriotic individuals and entities to create instability and inefficiencies in the economy.” The thinking is that Ecocash, which enables currency trading, is making it easier for people to dump the local currency. But here’s the thing: Ecocash, which said it suspended cash-in-cash-out functions (presumably because its banking lines will be cut) is still keeping in-app payment facilities open. And it said nothing about stopping its fairly popular service allowing people to buy cryptocurrency. Not surprisingly, since the ban “demand for bitcoin has skyrocketed,” according to African crypto news site, bitcoinke, with “sources claiming bitcoin is now selling at at 18% premium above the market rate.” 

OF MONEY AND MYTHS. I’m reading Stephanie Kelton’s book, “The Deficit Myth.” In a future edition of Money Reimagined, I’ll have more to say on the most influential modern monetary theory proponent’s explanation of its ideas. But for now I’ll just say that, while I’m not likely to be a convert to all its prescriptions, it seems clear that MMT is widely misunderstood by folks on both the left and the right – also, very much by the crypto industry. The latter is perhaps because people in crypto tend to skew more to the metallist school of money, rather than to chartalism. Either way, a clearer grasp of what MMT is all about would, I believe, help improve the industry’s discussion around government, money, trust and how blockchain-based systems can integrate with the existing one.

DeFi’s ‘Agricultural Revolution’ Has Ethereum Users Turning to Decentralized Exchanges. DEX’s, often touted as a fairer and safer way to trade cryptocurrencies, might finally have their use case: yield farming. In the past, as Brady Dale reports, most people haven’t wanted to self-custody, preferring institutions to manage the risks of holding their keys for them. But in DeFi, where people undertake dual borrowing-and-lending schemes to make big, quick returns on incentives and high interest rates, is better if you control the keys during the trade.
