Vitalik Buterin: The AI ​​era needs encrypted privacy mechanisms to protect API access patterns

CoinFeed reported on March 8th that Ethereum co-founder Vitalik Buterin stated that with the increasing prevalence of AI agents, cryptographic privacy technologies are crucial for protecting users' API call patterns and behavioral data. He pointed out that even with local AI agents, if external services can see all search or API call records, they can still infer the user's ongoing activities. Vitalik believes that an initial solution is to use mixnets to forward requests and hide the source of access, but service providers may require anti-abuse mechanisms and pay-per-call models due to DoS attacks, and in reality, these payment methods often rely on credit cards or stablecoin systems lacking privacy protection. Therefore, he emphasized the need for cryptographic payment solutions with privacy attributes.
