#以太坊安全计划 Ethereum Security Program focuses on consensus mechanism upgrades, Layer 2 expansion, and enhanced resistance to attacks. The PoS mechanism reduces the risk of 51% attacks, introducing staking withdrawal and penalty mechanisms to improve node security; Layer 2 solutions (such as Rollup) reduce the mainnet load and lower the probability of single points of failure; the security team continuously optimizes smart contract vulnerability detection tools and collaborates with auditing agencies to improve code security standards. Research on post-quantum cryptographic algorithms is advancing simultaneously to guard against future computational threats. However, the complexity of technology may give rise to new vulnerabilities, necessitating a balance between decentralization and security, while community governance and developer collaboration remain core defensive barriers.
