【Ethereum Researcher: The Difficulty and Cost of a 51% Attack on Ethereum is Higher than Bitcoin】According to Golden Finance and reported by Cointelegraph, Ethereum researcher Justin Drake stated that the cost to initiate a 51% attack on Bitcoin is lower compared to Ethereum, requiring about 10 billion dollars. He pointed out that to control the Ethereum chain, one would need to control over 50% of the staked ETH, which is currently valued at nearly 44.8 billion dollars, and the actual cost may be even 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 although there are theoretical risks, the threshold for launching a 51% attack in reality is extremely high for both BTC and ETH.
