Bootstraps & sync streams

Bootstrap snapshots and database sync streams for the XChain Platform: the fast path to bringing a new node online without parsing every block from genesis.

What lives here

Snapshots and live streams

Bootstraps

One-shot snapshots at /bootstraps/{service}/{coin}/{network}/. Download, verify, and restore via xchain-node bootstrap restore.

Indexer sync

REST snapshots + a WebSocket stream of indexer DB state at /{COIN}/indexer/, used by validators to stay current after the initial bootstrap.

Decoder sync

The same shape for the upstream decoder DB at /{COIN}/decoder/ (8 of 9 tables; mempool excluded).

Coin codes

Per-chain path prefixes

Paths use a short prefix, with T for testnet and R for regtest.

Operator notes

Before you download

Bootstraps are large (10 GB to 200+ GB). Use wget -c or aria2c so transfers can resume.
Each bootstrap ships with an embedded SHA-256 checksum; xchain-node bootstrap restore verifies it automatically before extracting.
After restore, the node catches up on blocks since the snapshot. Typically minutes to hours, not weeks.
This endpoint is intentionally not behind a CDN proxy (multi-GB downloads + long-lived WebSocket streams aren't proxy-friendly).
