According to online reports, Ethereum co-founder Vitalik Buterin emphasized at the EthCC Conference in France that the encryption industry needs to pay attention to specific user protection of decentralization. When he delivered a speech at the Ethereum Community Conference, he proposed practical testing of encryption projects, including leaving testing and insider attack testing to ensure user safety. At the same time, Vitalik Buterin warned that there are hidden vulnerabilities in the second-layer network, emphasized the importance of privacy as a default feature, and proposed three core test standards: 1. Exit the test (whether user assets are safe after the project party disappears); 2. Internal attack test (the ability of the system to resist internal evil); 3. Trusted Computing basics testing (the amount of code you need to trust to protect user assets).
