Urbit Runtime

Urbit is a personal server stack built from scratch. This repository contains Urbit's runtime environment, the lowest layer of the Urbit stack, which includes the Nock virtual machine, I/O drivers, event log, and snapshotting system.

Getting Started

For basic Urbit usage instructions, head over to urbit.org. For a high-level overview of the salient aspects of Urbit's architecture, visit developers.urbit.org. You might also be interested in joining the urbit-dev mailing list.

Packages

Urbit's runtime is broken down into a few separate layers, each of which is defined in its own package:

  • pkg/c3: A set of basic utilities for writing Urbit's style of C.
  • pkg/ent: A cross-platform wrapper for getentropy(2).
  • pkg/urcrypt: A standardized interface for calling various cryptographic functions used in the Urbit runtime.
  • pkg/ur: An implementation of jam and cue, Urbit's bitwise noun serialization and deserialization algorithms, respectively.
  • pkg/noun: The Nock virtual machine and snapshotting system.
  • pkg/vere: The I/O drivers, event log, and main event loop.

Build

See INSTALL.md.
