	Name
	MultiSig(const std::vector< std::string > & signer_set, uint64_t required_signatures)
bool	IsValid() const
uint64_t	RequiredSignatures() const
size_t	AuthorizedSignerCount() const
QuorumResult	EvaluateQuorum(const CollectedSignatures & collected_signatures, const std::vector< uint8_t > & payload) const Evaluates collected signatures against this instance's N-of-M policy.

Detailed Description¶

class sgns::multisig::MultiSig;

Configured N-of-M signature evaluator.

The constructor fixes the quorum policy for the evaluator's lifetime: required_signatures is N and the number of unique addresses in signer_set is M. A configuration is valid only when 1 <= N <= M.

Public Functions Documentation¶

function MultiSig¶

MultiSig(
    const std::vector< std::string > & signer_set,
    uint64_t required_signatures
)

function IsValid¶

bool IsValid() const

function RequiredSignatures¶

uint64_t RequiredSignatures() const

function AuthorizedSignerCount¶

size_t AuthorizedSignerCount() const

function EvaluateQuorum¶

QuorumResult EvaluateQuorum(
    const CollectedSignatures & collected_signatures,
    const std::vector< uint8_t > & payload
) const

Evaluates collected signatures against this instance's N-of-M policy.

For each (address, signature) pair, in order:

skip an address already counted
skip an address outside the configured signer set
skip an invalid signature
otherwise count the address as one valid unique signer

Invalid N-of-M configurations always fail closed with has_quorum == false.
