0This episode features a public speech by Ethereum co-founder Vitalik Buterin at the 12th Global Blockchain Summit in Shanghai. Vitalik reviews how blockchain technology has evolved over the past 15 years, arguing that the industry is moving beyond blockchain alone toward a broader technological stack combining blockchains with zero-knowledge proofs, programmable cryptography, and other advanced tools. As data analytics and AI become increasingly powerful, the privacy assumptions of early public blockchains are no longer sufficient, creating a greater need for new cryptographic approaches to privacy, scalability, and security.
Vitalik highlights technologies including SNARKs, STARKs, fully homomorphic encryption (FHE), and formal verification. He argues that zero-knowledge proofs are moving from long-term roadmaps into real protocols, while programmable cryptography could expand blockchain systems from determining "who can send what" to determining "who can see what." In this vision, blockchain will increasingly become a broader network encompassing L1s, L2s, off-chain computation, transaction pools, block building, and other components.
He also argues that AI can accelerate the development, verification, and understanding of complex cryptographic systems. As zero-knowledge proofs become more efficient and technologies such as formal verification and quantum-safe cryptography advance, developers may gain new ways to build decentralized applications with stronger privacy, scalability, and security guarantees.
