Expand description

A signature scheme used by validators.

Required Associated Types

Signature type.

Type representing an aggregate signature. This would presumably be a BLS signature, yet even with Schnorr signatures half-aggregation is possible. It could even be a threshold signature scheme, though that’s currently unexpected.

Type representing a signer of this scheme.

Required Methods

Verify a signature from the validator in question.

Aggregate signatures.

Verify an aggregate signature for the list of signers.
