The Ethereum Security Program aims to ensure the security and stability of the Ethereum network and its ecosystem. This program covers multiple levels, including protocol security, smart contract security, node security, and user education. Firstly, the core Ethereum development team continuously carries out protocol upgrades and vulnerability fixes to enhance 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. In addition, node operators are encouraged to adopt the latest security patches and configurations to guard against 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 is achieved through multi-party collaboration.
