One minute to understand the disappearance of V God @ VitalikButerin, who has been missing for nearly a month. Published three articles in a row -3 A Simple Roadmap for L2 Security and Final Confirmation 1. Expand the data space first, so that more L2 can run faster. 2. Establish a "three insurance" mechanism in the short term, which means allowing at least two out of the three technologies (optimistic verification, zero knowledge proof, hardware security zone) to be confirmed directly when they say "OK", reducing the time required. 3. The long-term goal is to achieve full automation and complete distrust, but ZK technology is not yet mature enough, so we need to compromise and gradually advance. 4. In the future, we will also establish a unified "packaging proof" system, which will be shared across the entire ecosystem, saving money and effort, and enabling all applications using ZK proof to be packaged and verified together, resulting in higher efficiency.
