Vitalik Buterin has released a working demo of an anonymous message board on Aztec, pairing fully private posting with an onchain moderation layer.
The Ethereum co-founder shared the project Sunday on Farcaster, calling it a "vibe-coded" toy version of the "anon billboard with moderation" concept he outlined in a 2022 blog post. The code is public on GitHub under his vbuterin account.
Buterin’s onchain message board
The billboard is built on Aztec. Users deposit ETH on Ethereum's (ETH) base layer, post messages anonymously on Layer 2, and later withdraw their ETH back to Layer 1, according to the repository. Posts carry no sender address in public call data and no link to the original deposit.
Buterin also noted that Aztec had reached stage 2 — the most decentralized tier on the Layer 2 maturity scale — in a follow-up cast, otherwise known as a post on the Farcaster platform.
