Vitalik Buterin: ZK-SNARKs and others have low efficiency, and Ethereum aims to achieve real-time proof

Ethereum founder Vitalik Buterin delivered a keynote speech titled "Receiving the Limits of Protocol Design" at the 2024 Hong Kong Web3 Carnival. Vitalik Buterin stated that technologies such as ZK-SNARKs, MPC, and FHE have efficiency and security issues. The Ethereum Slot takes 12 seconds to block, the regular block verification time is about 400 milliseconds, and the ZK-SNARK proof time is about 20 minutes. Ethereum's goal is to achieve real-time proof.
