Ethereum co-founder Vitalik Buterin has revealed how he runs his AI setup entirely on local hardware, using the open-source Qwen3.5:35B model.

He built a custom messaging daemon that blocks his AI agent from contacting third parties without manual approval.

Buterin avoids cloud-based tools due to privacy concerns, storing a full Wikipedia dump locally to reduce reliance on external searches.

He also restricts autonomous crypto transactions to $100 daily, requiring human confirmation for larger moves.

This approach aligns with his broader strategy of securing crypto holdings through decentralized, multi-signature wallets.

Research cited in his post shows that about 15% of community-built tools for OpenClaw, the fastest-growing GitHub repo, contain malicious code.
