This section of the docs contains guides and reference material for the three basic components of the system: the Arvo kernel, the Vere runtime and Azimuth, the PKI and identity system on the Ethereum blockchain.
Guides and reference material about Urbit's kernel Arvo, and its kernel modules called Vanes.
Urbit's runtime is called Vere. It interprets compiled Nock, handles I/O, and manages state checkpoints and the event log.
Urbit's indentity system and public-key infrastructure is called Azimuth, and lives on the Ethereum blockchain.
