Synchronization Using Snapshot (Recommended)
The Bifrost Network provides snapshots of the chain data. Snapshots are updated at regular intervals. This allows node operators to spend less time on data synchronization and reduce the load on the network.
Follow the link, and complete the snapshot download&export process.
Return to the process in the operation manual once complete.
Synchronization from the Genesis Block (Not Recommended)
This method does not require snapshots.
1. Block 0 to 336115
For initial synchronization, utilize bifrost-node 1.0.2 up to at least block 336115.
# After terminate existing bifrost-nodecd<YOUR-BASE-PATH-DIRECTORY>rmbifrost-nodewgethttps://github.com/bifrost-platform/bifrost-node/releases/download/v1.0.3/bifrost-nodechmod+xbifrost-node./bifrost-node--base-path./--chain./bifrost-testnet.json--port30333--pruningarchive--runtime-cache-size128
3. Complete synchronization
Synchronization is complete once “Syncing” does not appear in the log. Return to the process on the operation manual.
