pub struct GrandpaBlockImport<Backend, Block: BlockT, Client, SC> { /* private fields */ }
Expand description

A block-import handler for GRANDPA.

This scans each imported block for signals of changing authority set. If the block being imported enacts an authority set change then:

  • If the current authority set is still live: we import the block
  • Otherwise, the block must include a valid justification.

When using GRANDPA, the block import worker should be using this block import object.
