Thurin Labs builds open, decentralized identity infrastructure: PGP keys claimed on Ethereum addresses, checked by anyone, with no backend to trust and no data collected.
- thurin.id: look up anyone's PGP key by ENS name, address, or fingerprint, and claim your own on your Ethereum address
- Thurin CLI: the same from a terminal (
npx @thurinlabs/thurin@latest), plus a keyserver plain gpg can use - identity-kit: the one library that reads and checks claims, behind all of them
- PGPRegistry: the contract. Immutable, no admin, no fees
- mathom: air-gapped PGP key custody and signing, built from an old laptop
- noir-audit-skill: a Claude Code skill for auditing Noir zero-knowledge circuits
