Struct sc_consensus_grandpa::ThreeQuartersOfTheUnfinalizedChain

pub struct ThreeQuartersOfTheUnfinalizedChain;

Expand description

A custom voting rule that limits votes towards 3/4 of the unfinalized chain, using the given base and best_target to figure where the 3/4 target should fall.

Trait Implementations§

impl Clone for ThreeQuartersOfTheUnfinalizedChain

impl<Block, B> VotingRule<Block, B> for ThreeQuartersOfTheUnfinalizedChainwhere Block: BlockT, B: HeaderBackend<Block>,

fn restrict_vote( &self, backend: Arc<B>, base: &Block::Header, best_target: &Block::Header, current_target: &Block::Header ) -> VotingRuleResult<Block>

Restrict the given current_target vote, returning the block hash and number of the block to vote on, and None in case the vote should not be restricted. base is the block that we’re basing our votes on in order to pick our target (e.g. last round estimate), and best_target is the initial best vote target before any vote rules were applied. When applying multiple VotingRules both base and best_target should remain unchanged. Read more
