ChainCatcher news, according to Cointelegraph, Ethereum researcher Justin Drake stated that initiating a 51% attack on Bitcoin is less costly than on Ethereum, requiring approximately 10 billion USD. He pointed out that to control the Ethereum chain, one must control over 50% of the staked ETH, which is currently valued at nearly 44.8 billion USD, with actual costs potentially being higher. Drake emphasized that Ethereum’s PoS mechanism has social layer defenses that can identify and socially punish attackers, while Bitcoin’s PoW lacks this mechanism. Experts believe that, theoretically, there are risks, but the threshold for launching a 51% attack in reality is extremely high for both BTC and ETH.
