Wu Shuo learned that Vitalik Buterin, co-founder of Ethereum, released the "L2 Security and Finalization Roadmap" on the Ethereum Magicians forum, proposing a=>"3 out of 2" architecture based on optimistic proof (OP), zero knowledge proof (ZK), and trusted execution environment (TEE) to achieve faster and more secure Layer 2 finalization. The plan envisions that if ZK and TEE are validated simultaneously, they will be immediately terminated; If only one party confirms, wait for 7 days and pass OP verification; The security committee may intervene in updating the logic under specific conditions. Vitalik stated that this architecture can ensure security while avoiding dependence on a single ZK system. In addition, he also called for the construction of a universal ZK proof aggregation layer for the Ethereum ecosystem to reduce costs and enhance system interoperability. https://www.
