The static committee election

Fields§

§eligible_leaders: Vec<<T::SignatureKey as SignatureKey>::StakeTableEntry>

§stake_table: Vec<<T::SignatureKey as SignatureKey>::StakeTableEntry>

The nodes on the committee and their stake

§da_stake_table: Vec<<T::SignatureKey as SignatureKey>::StakeTableEntry>

The nodes on the committee and their stake

§indexed_stake_table: BTreeMap<T::SignatureKey, <T::SignatureKey as SignatureKey>::StakeTableEntry>

The nodes on the committee and their stake, indexed by public key

§indexed_da_stake_table: BTreeMap<T::SignatureKey, <T::SignatureKey as SignatureKey>::StakeTableEntry>
