The Ethereum Security Program aims to ensure the security and stability of the Ethereum network and its ecosystem. This program covers multiple aspects, including protocol security, smart contract security, node security, and user education. First, the Ethereum core development team continuously conducts protocol upgrades and vulnerability fixes, enhancing the network's resistance to attacks through hard forks and soft forks. Secondly, smart contract auditing tools and best practices are widely promoted to reduce contract vulnerabilities and the risk of hacker attacks. Additionally, node operators are encouraged to adopt the latest security patches and configurations to prevent DDoS attacks and other network threats. Finally, user education is an important component of the security program, helping users identify and avoid common risks such as phishing attacks and private key leaks by providing security guidelines and resources. The Ethereum Security Program promotes collaboration among multiple parties.
