Bitcoin vs. Ethereum: Examining 51% Attack Costs and Security Implications

Ethereum researcher Justin Drake recently compared the costs of 51% attacks on Bitcoin and Ethereum, highlighting a significant difference in attack feasibility and potential financial risks. According to Drake, a 51% attack on Bitcoin carries an estimated cost of $10 billion, while Ethereum’s target could reach over $44.8 billion due to its Proof-of-Stake mechanism. This finding points to a clear security advantage for Ethereum.
