Bybit’s $1.5bn loss rekindles Ethereum blockchain rollback chatter, critics say unlikely

A monolithic hack targeting cryptocurrency speech Bybit connected Friday rattled the market, resulting successful the nonaccomplishment of much than 401,000 Ethereum worthy astir $1.5 billion.

It has besides revived statement astir whether the Ethereum blockchain should beryllium “rolled back” successful response, echoing debates from the 2016 DAO hard fork.

In that incident, attackers exploited vulnerabilities successful a decentralized autonomous enactment to divert millions successful Etherum, prompting the assemblage to instrumentality a hard fork that restored the funds but divided the network.

Bybit CEO Ben Zhou was cautious successful his remarks erstwhile asked astir a rollback. “I truly don’t know. I’m not definite if it’s 1 man’s decision. Based connected the tone of the blockchain possibly it should beryllium a voting process to spot what the assemblage wants,” Zhou stated successful an X Spaces treatment yesterday.

He added that his squad was already successful talks with Ethereum co-founder Vitalik Buterin and the Ethereum Foundation for immoderate recommendations that mightiness assistance mitigate the fallout.

The statement rapidly spilled implicit into societal media. Former BitMEX CEO Arthur Hayes took to Twitter, posing a question to Ethereum co-founder Vitalik Buterin: “Will you advocator to rotation backmost the concatenation to assistance Bybit?”

In what appears to beryllium a tongue-in-cheek remark, Hayes added: “ETH stopped being wealth successful 2016 aft the DAO hack hardfork. If the assemblage wanted to bash it again, I would enactment it due to the fact that we already voted nary connected immutability successful 2016 wherefore not bash it again?”

Amid the exchanges, Laura Shin of the Unchained podcast added immoderate context and clarification regarding “rollback” proposals, saying “I’m definite they wouldn’t.”

Shin clarified that the word “rollback” originates from Bitcoin’s design, wherever each transaction is linked successful a continuous concatenation of custody.

In Bitcoin, reversing 1 transaction would necessitate undoing each consequent transactions to support the chain’s integrity.

However, Ethereum uses a exemplary wherever balances are updated straight done astute contracts and transactions, meaning determination isn’t a single, traceable concatenation that tin beryllium reversed successful the aforesaid manner.

Instead of a existent rollback, what occurred during the DAO incidental was an “irregular authorities change” that reallocated funds from compromised contracts without rewinding the full blockchain.
