Azimuth
Azimuth is Urbit's identity registry deployed on the Ethereum blockchain. It serves as the source of truth for Urbit point ownership and network identity.
What is Azimuth?
Azimuth is an ERC-721 based public key infrastructure (PKI) that manages Urbit identities. Each Urbit identity is represented as an NFT on Ethereum, providing cryptographic proof of ownership and enabling decentralized identity management.
Key Features:
- Galaxies, stars, planets, moons, and comets form a tiered hierarchical identity system
- Cryptographic proof of identity ownership stored on Ethereum
- Higher-tier points sponsor lower-tier points, establishing network relationships
- All identity operations are recorded on Ethereum for transparency
Azimuth in Zenith
Zenith uses Azimuth as the basis for network participation and governance:
Validator Eligibility: Only verified Azimuth galaxy owners can become validators on Zenith.
Transaction Bundling: Star owners participate as transaction bundlers, aggregating transactions from planets.
Identity Verification: The lockdrop process requires cryptographic attestations linking Azimuth ownership to Zenith accounts.
Ownership Tracking: The Azimuth Watcher monitors ownership changes in real-time, automatically jailing and slashing validators who transfer their galaxy ownership.
Sponsorship Model: Zenith preserves Urbit's sponsorship relationships, with stars submitting bundles to their sponsoring galaxy validators.
