Blockstream CEO claims Ethereum Virtual Machine’s complexity enabled hackers to drain funds
Prominent crypto figure Adam Back, known as a cypherpunk and CEO of Blockstream, took to X to share his thoughts on the recent Bybit hack, where the exchange lost $1.4 billion in ETH.
Back pointed to Ethereum Virtual Machine (EVM) as the key factor that allowed hackers to successfully exploit the system and drain Bybit’s funds.
❌ Back Criticizes EVM Complexity as Ethereum’s Weakness
According to Adam Back, the primary issue lies in the complexity of Ethereum transactions, making the network vulnerable to attacks.
📌 How did hackers exploit this weakness?
🔹 EVM is overly complex, making it difficult for hardware wallets to interpret transactions.
🔹 Blind signing of Ethereum transactions introduces security risks.
🔹 Bybit attempted to transfer $100 million in ETH from its cold wallet to a hot wallet, but hackers manipulated the process, ultimately draining $1.4 billion in total.
Back described EVM as fragile, unsecure, and overly complicated, claiming that these weaknesses increase the risk of exploits.
🔍 How Did the Bybit Hack Happen?
Bybit suffered one of the largest crypto exploits in history.
🔸 The hack was likely carried out by North Korea’s Lazarus Group, a state-backed hacking organization.
🔸 Hackers exploited vulnerabilities in Ethereum smart contracts while Bybit was transferring funds internally.
🔸 Bybit claims that the liquidity gap in ETH has now been fully closed.
🤔 Could Ethereum Perform a Rollback? A Throwback to the DAO Hack in 2016
After the attack, several Bitcoin maximalists, including Samson Mow (CEO of JAN3), sarcastically asked Vitalik Buterin if Ethereum would roll back the blockchain to recover the lost funds.
This references the infamous 2016 DAO hack, where after a $60 million ETH exploit, the Ethereum community decided to hard fork, leading to the creation of Ethereum Classic (ETC).
🚨 However, Ethereum has no plans for a rollback this time – the Ethereum team stated that the hacker’s transactions were as valid as any other transaction on the network.
📢 What’s Next? Is Bitcoin’s Dominance Rising?
Back emphasized that Bitcoin is growing in dominance, while Ethereum faces criticism over its EVM security flaws.
⚠️ Could this hack be a wake-up call for the development of safer blockchain technologies?
⚠️ Will Bitcoin and simpler blockchain structures become the future?
