The syncer downloads and verifies large numbers of blocks from peers to Zebra.

It is used when Zebra is a long way behind the current chain tip.

Modules

A task that gossips newly verified block::Hashes to peers.

A channel which holds a list of recent syncer response lengths.

Structs

Helps work around defects in the bitcoin protocol by checking whether the returned hashes actually extend a chain tip.

A helper type which holds a list of recent syncer response lengths. These sync lengths can be used to work out if Zebra has reached the end of the chain.

A helper type to determine if the synchronizer has likely reached the chain tip.

Enums

Errors that can occur when gossiping committed blocks
