Vitalik Buterin Unveils Anonymous Board with AI Moderation on Aztec

Ethereum co-founder Vitalik Buterin has published a demo version of an anonymous message board on GitHub, built on the Aztec privacy-focused rollup.

The concept works as follows: a user deposits ETH via a smart contract on the Ethereum mainnet, which then allows them to post messages on the rollup. The user’s address and deposit amount remain public. When deploying the contract, a moderator is also assigned — this role can be filled by a local daemon running a large language model (LLM).

Buterin described the current iteration as a prototype but noted that it is already capable of enabling “interesting things.”
