Expand description

Accumulates votes until a certificate is formed. This implementation works for all simple vote and certificate pairs

Fields§

§vote_outcomes: HashMap<Commitment<VersionedVoteData<TYPES, <VOTE as Vote<TYPES>>::Commitment, V>>, (U256, BTreeMap<TYPES::SignatureKey, (<TYPES::SignatureKey as SignatureKey>::PureAssembledSignatureType, Commitment<VersionedVoteData<TYPES, <VOTE as Vote<TYPES>>::Commitment, V>>)>)>

§signers: HashMap<Commitment<VersionedVoteData<TYPES, <VOTE as Vote<TYPES>>::Commitment, V>>, (BitVec, Vec<<TYPES::SignatureKey as SignatureKey>::PureAssembledSignatureType>)>

A bitvec to indicate which node is active and send out a valid signature for certificate aggregation, this automatically do uniqueness check And a list of valid signatures for certificate aggregation

§phantom: PhantomData<(TYPES, VOTE, CERT)>

version information

Implementations§
