Vitalik: The next payment standard in the Agent era might be ZK Payments Ethereum founder Vitalik Buterin @VitalikButerin mentioned during an interview with OKX that the next step for payments at the protocol level within the native Agent standard could be ZK Payments. He believes that in AI scenarios, persistent pseudonymous identities will eventually lose all privacy. The team is currently developing a ZK API to isolate each request, protecting privacy without requiring an on-chain transaction for every request, while integrating margin mechanisms to prevent abuse.
