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.
