Struct sc_consensus_babe::BabeBlockImport

source · [−]

pub struct BabeBlockImport<Block: BlockT, Client, I> { /* private fields */ }

Expand description

A block-import handler for BABE.

This scans each imported block for epoch change signals. The signals are tracked in a tree (of all forks), and the import logic validates all epoch change transitions, i.e. whether a given epoch change is expected or whether it is missing.

The epoch change tree should be pruned as blocks are finalized.
