A recent analysis by Ethereum researcher Justin Drake highlights a notable difference in blockchain security models. According to Drake, launching a 51% attack on Ethereum would cost approximately $44.8 billion, while a similar attack on Bitcoin could cost around $10 billion.
The key reason? Ethereum’s Proof-of-Stake (PoS) system requires validators to stake large amounts of $ETH, making attacks more financially prohibitive. In contrast, Bitcoin’s Proof-of-Work (PoW) system depends on mining power, which some argue may become less secure over time due to declining block rewards.
Drake also points out that Ethereum’s social layer—its active and engaged community—adds another layer of defense not present in Bitcoin's structure.
Meanwhile, Grant Hummer, a supporter of Bitcoin, has expressed concerns about Bitcoin’s long-term security budget, especially as mining rewards halve over time.
While both networks remain highly secure, the cost disparity could shape investor and developer decisions as the industry evolves.
