Vitalik Buterin Builds Anonymous Onchain Billboard Demo on Aztec

Ethereum co-founder Vitalik Buterin built an anonymous billboard demo on the Aztec blockchain using a "vibe-coding" approach. The project features onchain moderation, a dedicated censor role, and a local LLM daemon that flags inappropriate content. The experiment showcases how privacy-preserving blockchains can integrate AI-driven moderation tools.
