Struct sc_consensus_grandpa::AuthoritySetHardFork

source · 
pub struct AuthoritySetHardFork<Block: BlockT> {
    pub set_id: SetId,
    pub block: (Block::Hash, NumberFor<Block>),
    pub authorities: AuthorityList,
    pub last_finalized: Option<NumberFor<Block>>,
}
Expand description

A descriptor for an authority set hard fork. These are authority set changes that are not signalled by the runtime and instead are defined off-chain (hence the hard fork).

Fields§

§set_id: SetId

The new authority set id.

§block: (Block::Hash, NumberFor<Block>)

The block hash and number at which the hard fork should be applied.

§authorities: AuthorityList

The authorities in the new set.

§last_finalized: Option<NumberFor<Block>>

The latest block number that was finalized before this authority set hard fork. When defined, the authority set change will be forced, i.e. the node won’t wait for the block above to be finalized before enacting the change, and the given finalized number will be used as a base for voting.
