# 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.
