Ethereum 'Roll Back' Suggestion Has Sparked Criticism. Here's Why It Won't Happen
On Friday, cryptocurrency exchange Bybit was allegedly hacked by North Korea's Lazarus group, which drained nearly $1.4 billion in ether (ETH) from the exchange.
Following the hack, Arthur Hayes, BitMEX co-founder and claiming to be a major ether (ETH) holder, wrote a post on X to Ethereum co-founder Vitalik Buterin on whether he will 'advocate to roll back the chain to help @Bybit_Official.' Meanwhile, in an X spaces session, Bybit's CEO Ben Zhou revealed that his team had also reached out to the Ethereum Foundation to see if it was something the network would consider, noting that such a decision should be based on what the network's community wants.
Hayes's post immediately provoked a fierce reaction from the Ethereum community, which was firm in its belief that it wouldn't happen. Some even questioned whether the BitMEX founder was joking. CoinDesk reached out to Hayes over X to clarify his comments.
Ethereum members, like the core developer teams, are vastly against 'rolling back' the network because it would override core elements of decentralization. If Buterin decided on his own that it would happen, then that would be seen as the end of Ethereum's ethos, which heavily involves various developer teams and other community members when it comes to the health and state of the blockchain.
'Rolling back the chain would give ETH no purpose. What's the point if you can just change rules,' said user @the_weso in a post on X.
Some outside the Ethereum community pointed to the 2016 DAO hack as an example when $60 million in ETH was stolen. The network went forward with a hard fork, splitting the old network into two, and the new chain continued on as Ethereum.
That hard fork was not a 'rollback,' though; it was known as an 'irregular state transition.' Ethereum technically can't 'roll back' the network because it relies on an account model, where accounts hold users' ETH.
At the time of the hack, developers upgraded their nodes to a new client or software. Those who didn't upgrade their nodes were still on the old chain, which became known as Ethereum Classic.
When the nodes upgraded to the new software, the stolen ETH could move from one Ethereum account address to the next.
'The 'irregular state change' that they implemented at the time of the DAO hard fork was this: they airlifted all the ETH in the DAO smart contracts out to a refund contract that would send you 1 ETH for every 100 DAO tokens you sent in,' wrote Laura Shin of Unchained in a post on X.

Bitcoin Quickly Plunges Below $103K, With Volatility Burst Spurring $450M in Crypto Liquidations
What started as a positive day for crypto markets quickly reversed during the U.S. session with bitcoin BTC sliding below $103,000 from the $106,500 level just hours earlier. At press time, bitcoin had pared some of the losses, returning to $103,200, down 1.2% over the past 24 hours. Other large cryptocurrencies endured steeper declines. Ethereum's ether ETH saw a sharp 4.5% drop in just 90 minutes to as low as $2,372, with trading volume spiking to nearly 800,000 ETH, nearly eight times the average hourly volume, per CoinDesk data. Solana's SOL SOL, dogecoin DOGE and Cardano's ADA ADA were 3%-5% lower over the same period. The volatility burst caught many traders off-guard, liquidating about $450 million in derivatives trading positions on centralized exchanges across all digital assets, CoinGlass data shows. Some $387 million of liquidations were tied to long positions that bet on profiting from rising prices. While macro risks abound — among them the ongoing conflict between Israel and Iran — there was no immediate external reason for the sudden price swing. The S&P 500 and the Nasdaq 100 indexes only inched lower during the day. Zooming out, BTC continues to trade within a sideways range between $100,000 and $110,000, consolidating just below its all-time record level. "The mixed view of whether BTC will go above $110,000 again or drop into the $90,000 area doesn't surprise me at all and underscores the overall indecision people and markets feel," said James Toledano, chief operating officer at Unity Wallet. "The present BTC stalemate reflects a market caught between bullish long-term sentiment and short-term macroeconomic and geopolitical uncertainty," he added.

ETH Under $2,500: Friday Sees Highest Outflows From Spot ETH ETFs This Month
Ether (ETH) ETH posted a modest recovery on Saturday after a volatile week marked by outsized institutional outflows. On Friday, June 20, spot ETH ETFs listed in the U.S. recorded $11.3 million in net outflows — the largest single-day decline in June, according to data from Farside Investors. The pullback was led by BlackRock's ETHA ETF, which saw a $19.7 million outflow — its first and only negative flow this month. In contrast, Grayscale's ETHE product attracted $6.6 million, and VanEck's ETHV ETF added $1.8 million, partially offsetting losses. No other issuers recorded inflows or outflows. The data suggests large institutions may be reducing their ETH exposure, even as select funds like Grayscale continue to attract capital. The ETF flow figures emerged alongside a technical rebound in price. Ether briefly dipped to $2,372.85 on Friday in a heavy sell-off marked by a volume spike nearly five times the daily average, but swiftly recovered as buyers stepped in around the $2,420–$2,430 range, according to CoinDesk Research's technical analysis model. This area has since formed a solid support zone, validated by multiple low-volume tests suggesting accumulation. The 24-hour trading volume surged 18.97% above the 7-day moving average, reflecting elevated trading interest during the price recovery. ETH closed near $2,445 and formed an ascending trendline of higher lows, though key resistance remains at the $2,480–$2,500 level. Technical Analysis Highlights ETH-USD posted a 24-hour trading range of $186.44 (7.25%), with a steep sell-off to $2,372.85 marking the session low. The drop occurred during the 17:00 hour and was accompanied by a sharp spike in trading volume, reaching 993,622 units—nearly 5x the daily average. A key support zone formed between $2,420 and $2,430, reinforced by multiple successful retests with progressively lower sell-side volume. ETH reclaimed 38.2% of the Fibonacci retracement from the sell-off and built an ascending trendline supported by higher lows. During the 08:00–09:00 hour, volume accelerated again, signaling bullish momentum and lifting price toward the $2,445 level. In the final hour, ETH traded within a narrow $5.83 band, ranging from $2,440.14 to a close of $2,443.45. A late-session rally peaked at $2,447.02 (11:38), with an intra-candle volume burst of 4,532 units. The price then dipped slightly but found immediate support at $2,439.38, continuing to respect the ascending short-term trendline.
