Ethereum Security Program #以太坊安全计划 focuses on technological upgrades and ecological protection: 1. Strengthening the consensus layer, continuously optimizing the randomness of verification nodes in the PoS mechanism to resist Sybil attacks; 2. Upgrading the smart contract security toolchain, implementing a formal verification framework for Solidity, allowing developers to pre-check for reentrancy vulnerabilities; 3. Anti-quantum computing threats, developing post-quantum signature algorithms based on STARKs; 4. Establishing Layer 2 security standards, mandating OP/zk-Rollups to set up escape pod mechanisms; 5. The community initiates the 'White Hat Circuit Breaker' protocol, automatically freezing abnormal on-chain transactions and triggering governance votes. Security is the lifeline of public chains, requiring coordinated defense of both software and hardware.
