In a recent interview, Ethereum researcher Justin Drake discussed the security models of Bitcoin and Ethereum, highlighting different attack costs.
Cost of Attacking Bitcoin
Drake noted that a successful 51% attack on Bitcoin would cost around **$10 billion**. This figure includes the costs of hardware, electricity, and coordination needed to gain control of Bitcoin's hash rate.
Advantages of Ethereum's PoS
Attacking Ethereum under its PoS model is significantly more complex: an attacker would need to control over 50% of all staked ETH, with a total estimated value of **$44.8 billion**. Moreover, ETH prices may rise in response to an attack attempt, further complicating any malicious actions. Unlike Bitcoin miners, who could sell their hardware post-attack, Ethereum attackers risk losing their staked ETH permanently, creating a financial barrier against malicious activities.
Discussion on Bitcoin's Security
The debate over whether Ethereum's PoS provides greater protection than Bitcoin's PoW is ongoing. While Bitcoin remains the most recognized cryptocurrency, Ethereum's architecture may position it as a more resilient blockchain. Both networks have proven robust and secure so far, but the question of Bitcoin's long-term security remains open.
Justin Drake's comments highlight the differences in security approaches in cryptocurrencies and raise interest in future architectural changes.
