Struct CoreVerifier

pub struct CoreVerifier {
    pub eligible_parties: Vec<MerkleTreeLeaf>,
    pub total_stake: Stake,
}

Full node verifier including the list of eligible signers and the total stake of the system.

Fields

eligible_parties: Vec<MerkleTreeLeaf>

List of registered parties.

total_stake: Stake

Total stake of registered parties.

Implementations

impl BasicVerifier

pub fn new(public_signers: &[(BlsVerificationKey, Stake)]) -> Self

Setup a basic verifier for given list of signers. * Collect the unique signers in a hash set, * Calculate the total stake of the eligible signers, * Sort the eligible signers.

pub fn setup(public_signers: &[(BlsVerificationKey, Stake)]) -> Self

👎Deprecated since 0.5.0: Use new instead

pub fn select_valid_signatures_for_k_indices( total_stake: &Stake, params: &Parameters, msg: &[u8], sigs: &[SingleSignatureWithRegisteredParty], ) -> Result<Vec<SingleSignatureWithRegisteredParty>, AggregationError>

Given a slice of sig_reg_list, this function returns a new list of sig_reg_list with only valid indices. In case of conflict (having several signatures for the same index) it selects the smallest signature (i.e. takes the signature with the smallest scalar). The function selects at least self.k indexes.

Error

If there is no sufficient signatures, then the function fails.

pub fn dedup_sigs_for_indices( total_stake: &Stake, params: &Parameters, msg: &[u8], sigs: &[SingleSignatureWithRegisteredParty], ) -> Result<Vec<SingleSignatureWithRegisteredParty>, AggregationError>
