In this episode of Friends of OKX Wallet, Ethereum co-founder Vitalik Buterin discusses the long-term convergence of AI and crypto. He talks about the role Ethereum could play in the agent era: rather than serving as a traditional “operating system,” blockchain is better understood as a public data layer, an on-chain computation layer, and an economic layer for multi-party coordination.
As AI agents begin to interact on-chain at scale, Ethereum will need to offer more than lower costs and higher throughput. It will also need stronger privacy, verifiable security, minimal identity disclosure, and an L2 ecosystem tailored to different application needs.
Vitalik argues that humans will remain the users, while AI becomes a new interface and execution layer. Wallets may evolve from standalone products into secure software capability layers that AI can call and orchestrate. For identity, users should avoid revealing who they are in full, and instead prove only what is necessary, such as reputation or source of funds, through zero-knowledge proofs.
On scaling, Vitalik says L2s should not simply copy the EVM. Instead, they should start from application needs and provide specific functions such as order matching, low-cost execution, or privacy. For Agent product experience, he emphasizes local AI, privacy, security, formal verification, and alignment with user interests. He also points to ZK Payments and ZK API as promising foundations for Agent-native payments and interaction standards.
