Ethereum co-founder Vitalik Buterin said he has packaged zkAPI, Tor, extra cover traffic, and local LLM prompt rewriting into a daemon compatible with the OpenAI API, while adding a "paranoid mode" to his personal agent framework, pi. In his description, each conversation gets its own Tor circuit, requests are obscured with random cover traffic, zkAPI is used to prevent identity leakage during payments, and prompts are rewritten by a local model. Buterin also said the agent is wrapped with bwrap sandboxing and torsocks, with all operations routed through Tor. He described the setup as already fairly usable, though latency rises noticeably, especially when starting a new conversation. Buterin added that Tor is not the best fit for this kind of use case, and said a dedicated mixnet would be a better design. He also noted that cheaper zkAPI deposit and withdrawal gas costs are set to go live on mainnet.
Ethereum co-founder Vitalik Buterin said on Oct. 16 that he has packaged zkAPI, Tor, extra cover traffic, and local large language model prompt rewriting into a daemon that is compatible with the OpenAI API, and added a "paranoid mode" to his personal agent framework, pi.
How the privacy setup works
According to Buterin, each conversation is assigned a separate Tor circuit. Requests are masked with random cover traffic, zkAPI is used to avoid identity leakage during the payment process, and prompts are rewritten by a local model.
Current trade-offs
Buterin said the agent is also wrapped with bwrap sandboxing and torsocks, with all operations routed through Tor. He described the system as already fairly usable, but said latency increases significantly, especially when a new conversation is created.
What Buterin wants next
He added that Tor is not the optimal tool for this type of scenario, and said a dedicated mixnet would be more suitable. Buterin also said cheaper zkAPI deposit and withdrawal gas costs will soon go live on mainnet.
