According to Wu, Ethereum co-founder Vitalik Buterin has unveiled his personally developed privacy AI Agent solution, integrating zkAPI, the Tor network, random cover traffic, and local large model prompt rewriting functionality into the AI Agent tool, pi. This solution assigns a separate Tor circuit to each conversation, hides payment-related information via zkAPI, and rewrites request content using the local Qwen model. Vitalik mentioned that the solution is already somewhat practical, but there are still noticeable delays when starting new conversations, and Tor offers limited protection against timing correlation analysis by colluding service providers and entry nodes. He suggested that a dedicated mixnet might be needed in the future. He also revealed that the Gas costs for deposits and withdrawals using zkAPI on the Ethereum mainnet are about to be further reduced. https://www.(wublock123.com)/news/vitalik-privacy-ai-agent-zkapi-tor-local-model-70205
