Previously, the initial Azimuth snapshot was stored in Clay and shipped in the pill. This causes several problems: - It bloats the pill - Updating the snapshot added large blobs to Clay's state. Even now that tombstoning is possible, you don't want to have to do that regularly. - As a result, the snapshot was never updated. - Even if you did tombstone those files, it could only be updated as often as the pill - And those updates would be sent over the network to people who didn't need them This moves the snapshot out of the pill and refactors Azimuth's initialization process. On boot, when app/azimuth starts up, it first downloads a snapshot from bootstrap.urbit.org and uses that to initialize its state. As before, updates after this initial snapshot come from an Ethereum node directly and are verified locally. Relevant commands are: - `-azimuth-snap-state %filename` creates a snapshot file - `-azimuth-load "url"` downloads and inits from a snapshot, with url defaulting to https://bootstrap.urbit.org/mainnet.azimuth-snapshot - `:azimuth &azimuth-poke-data %load snap-state` takes a snap-state any way you have it Note the snapshot is downloaded from the same place as the pill, so this doesn't introduce additional trust beyond what was already required. When remote scry is released, we should consider allowing downloading the snapshot in that way. |

Urbit
Urbit is a personal server stack built from scratch. It has an identity layer (Azimuth), virtual machine (Vere), and operating system (Arvo).
A running Urbit "ship" is designed to operate with other ships peer-to-peer. Urbit is a general-purpose, peer-to-peer computer and network.
This repository contains:
- The Arvo OS
- herb, a tool for Unix control of an Urbit ship
- Source code for Landscape's web interface
- Source code for the vere virtual machine.
For more on the identity layer, see Azimuth. To manage your Urbit identity, use Bridge.
Install
To install and run Urbit, please follow the instructions at urbit.org/using/install. You'll be on the live network in a few minutes.
If you're interested in Urbit development, keep reading.
Development
Urbit uses Nix to manage builds. On Linux and macOS you can install Nix via:
curl -L https://nixos.org/nix/install | sh
You can optionally setup Nix to pull build artefacts from the binary cache that continuous integration uses. This will improve build times and avoid unnecessary recompilations of common dependencies. Once Nix has been installed you can setup Cachix via:
nix-env -iA cachix -f https://cachix.org/api/v1/install
cachix use ares
The Makefile in the project's root directory contains useful phony targets for building, installing, testing, and so on. You can use it to avoid dealing with Nix explicitly.
To build the Urbit virtual machine binary, for example, use:
make build
The test suite can similarly be run via a simple:
make test
Note that some of the Makefile targets need access to pills tracked via git LFS, so you'll also need to have those available locally:
git lfs install
git lfs pull
