Arthur Hayes Proposes Rolling Back Ethereum Network to Negate $1.4B Bybit Hack

Arthur Hayes, BitMEX co-founder and major ether (ETH) holder, asked Ethereum co-founder Vitalik Buterin to rollback the network in order to assist hacked exchange Bybit, which lost nearly $1.4 billion in ether (ETH) on Friday.
«@VitalikButerin will you advocate to roll back the chain to help @Bybit_Official. My own view as a mega $ETH bag holder is $ETH stopped being money in 2016 after the DAO hack hardfork. If the community wanted to do it again, I would support it because we already voted no on immutability in 2016 [wh]y not do it again?» Hayes said on X.
Buterin was yet to reply as of time of publication.
The Bybit hack came into light on Friday when on-chain analyst ZachXBT noted suspicious outflows of over $1.4 billion from the exchange, with the attacker quickly swapping mETH and stETH for ether through a decentralized exchange.
The attacker then split 10,000 ETH to 39 different addresses and another 10,000 ETH to nine addresses, Gautham Santhosh, co-founder of Polynomial.fi, explained on X.
Bybit CEO Ben Zhou said that the hacker «took control of the specific ETH cold wallet and transferred all the ETH in the cold wallet to this unidentified address.» Zhou confirmed that the exchange «is solvent even if this hack loss is not recovered.»
One of the potential ways to address hacking is to roll back the blockchain. It involves reverting the blockchain to a state before the occurrence of a specific event, in this case, the hack. That way, malicious transactions resulting from the hack can be erased, effectively restoring lost or stolen funds. Implementing a rollback requires consensus from the network participants.
For instance, in 2016, the Ethereum network was rolled back using a hard fork to reverse a theft of $60 million in ether from The DAO (30% of all ETH in circulation back then). The hard fork split the chain into two – Ethereum and Ethereum Classic.
In 2019, Binance’s CEO Changpeng Zhao and his team considered pushing for a rollback on the Bitcoin network following a $40 million hack. However, the Bitcoin mining community criticized the idea of going back against the principle of decentralization and immutability, which are fundamental to blockchain technology.
Immutability is a security feature that prevents data from being changed after it’s added to the blockchain to make it trustworthy and tamper-proof. There are similar concerns regarding a potential Ethereum rollover.
«I wish we could roll back for the Bybit hack, I’m not against the idea. But the DAO hack was 15% of ETH with a clean recovery path. Today, a rollback would break bridges, stablecoins, L2s, RWAs and so much more. ETH ecosystem is just too interconnected now for a clean solution like 2016,» Santhosh said.
Sina 21st Capital explained that Ethereum is now stuck between a rock and a hard place.
«Ethereum is toast. They can roll back the chain and destroy what is left of the decentralization claim or allow North Korean baad actors to keep $1.4B of ETH and unleash an eternal internal battle. Either way, it is terrible,» Sina 21st Capital said on X.
Ether has dropped nearly 3% in 24 hours, but continues to trade rangebound between $2,600 and $2,800, CoinDesk data show.

Strategy Bought $27M in Bitcoin at $123K Before Crypto Crash

Strategy (MSTR), the world’s largest corporate owner of bitcoin (BTC), appeared to miss out on capitalizing on last week’s market rout to purchase the dip in prices.
According to Monday’s press release, the firm bought 220 BTC at an average price of $123,561. The company used the proceeds of selling its various preferred stocks (STRF, STRK, STRD), raising $27.3 million.
That purchase price was well above the prices the largest crypto changed hands in the second half of the week. Bitcoin nosedived from above $123,000 on Thursday to as low as $103,000 on late Friday during one, if not the worst crypto flash crash on record, liquidating over $19 billion in leveraged positions.
That move occurred as Trump said to impose a 100% increase in tariffs against Chinese goods as a retaliation for tightening rare earth metal exports, reigniting fears of a trade war between the two world powers.
At its lowest point on Friday, BTC traded nearly 16% lower than the average of Strategy’s recent purchase price. Even during the swift rebound over the weekend, the firm could have bought tokens between $110,000 and $115,000, at a 7%-10% discount compared to what it paid for.
With the latest purchase, the firm brought its total holdings to 640,250 BTC, at an average acquisition price of $73,000 since starting its bitcoin treasury plan in 2020.
MSTR, the firm’s common stock, was up 2.5% on Monday.

Crypto Markets Today: Bitcoin and Altcoins Recover After $500B Crash

The crypto market staged a recovery on Monday following the weekend’s $500 billion bloodbath that resulted in a $10 billion drop in open interest.
Bitcoin (BTC) rose by 1.4% while ether (ETH) outperformed with a 2.5% gain. Synthetix (SNX, meanwhile, stole the show with a 120% rally as traders anticipate «perpetual wars» between the decentralized trading venue and HyperLiquid.
Plasma (XPL) and aster (ASTER) both failed to benefit from Monday’s recovery, losing 4.2% and 2.5% respectively.
Derivatives Positioning
- The BTC futures market has stabilized after a volatile period. Open interest, which had dropped from $33 billion to $23 billion over the weekend, has now settled at around $26 billion. Similarly, the 3-month annualized basis has rebounded to the 6-7% range, after dipping to 4-5% over the weekend, indicating that the bullish sentiment has largely returned. However, funding rates remain a key area of divergence; while Bybit and Hyperliquid have settled around 10%, Binance’s rate is negative.
- The BTC options market is showing a renewed bullish lean. The 24-hour Put/Call Volume has shifted to be more in favor of calls, now at over 56%. Additionally, the 1-week 25 Delta Skew has risen to 2.5% after a period of flatness.
- These metrics indicate a market with increasing demand for bullish exposure and upside protection, reflecting a shift away from the recent «cautious neutrality.»
- Coinglass data shows $620 million in 24 hour liquidations, with a 34-66 split between longs and shorts. ETH ($218 million), BTC ($124 million) and SOL ($43 million) were the leaders in terms of notional liquidations. Binance liquidation heatmap indicates $116,620 as a core liquidation level to monitor, in case of a price rise.
Token Talk
By Oliver Knight
- The crypto market kicked off Monday with a rebound in the wake of a sharp weekend leverage flush. According to data from CoinMarketCap, the total crypto market cap climbed roughly 5.7% in the past 24 hours, with volume jumping about 26.8%, suggesting those liquidated at the weekend are repurchasing their positions.
- A total of $19 billion worth of derivatives positions were wiped out over the weekend with the vast majority being attributed to those holding long positions, in the past 24 hours, however, $626 billion was liquidated with $420 billion of that being on the short side, demonstrating a reversal in sentiment, according to CoinGlass.
- The recovery has been tentative so far; the dominance of Bitcoin remains elevated at about 58.45%, down modestly from recent highs, which implies altcoins may still lag as capital piles back into safer large-cap names.
- The big winner of Monday’s recovery was synthetix (SNX), which rose by more than 120% ahead of a crypto trading competition that will see it potentially start up «perpetual wars» with HyperLiquid.
