Vitalik: Blockchain has evolved from a mere ledger to a cryptography-based secure computing network.

September 23: Ethereum co-founder Vitalik Buterin delivered a keynote speech at the 12th Global Blockchain Summit. He stated that in its early days, blockchain possessed characteristics such as openness, neutrality, and security, but suffered from issues including non-scalability, complete transparency, and lack of privacy protection. Privacy transactions and scalable verification brought by zero-knowledge proofs have moved from planning into actual EIPs incorporated into Ethereum's roadmap, technologies such as fully homomorphic encryption have also begun to be applied, and indistinguishability obfuscation may be applied on-chain in the future.

He stated that parallel block construction and proving can achieve greater scalability. The Web3 industry's focus has expanded from digital assets to digital assets and information, covering the complete process including the user end, transaction mempool, and on-chain. With the development of AI, providing cryptographic rules to AI for automated formal verification can improve verification efficiency.
