Struct sc_finality_grandpa::warp_proof::WarpSyncFragment

pub struct WarpSyncFragment<Block: BlockT> {
    pub header: Block::Header,
    pub justification: GrandpaJustification<Block>,
}

A proof of an authority set change.

Fields

header: Block::Header

The last block that the given authority set finalized. This block should contain a digest signaling an authority set change from which we can fetch the next authority set.

justification: GrandpaJustification<Block>

A justification for the header above which proves its finality. In order to validate it the verifier must be aware of the authorities and set id for which the justification refers to.
