BLS

BLS

This file documents a contract which is not yet deployed to Mainnet.

Library for verification of 2-pairing-check BLS signatures, including basic, aggregated, or reconstructed threshold BLS signatures, generated using the AltBn128 curve.

sign

function sign(bytes message, uint256 secretKey) external view returns (bytes)

Creates a signature over message using the provided secret key.

verifyBytes

function verifyBytes(bytes publicKey, bytes message, bytes signature) external view returns (bool)

Wraps the functionality of BLS.verify, but hashes a message to a point on G1 and marshal to bytes first to allow raw bytes verification.

verify

function verify(bytes publicKey, bytes message, bytes signature) public view returns (bool)

Verify performs the pairing operation to check if the signature is correct for the provided message and the corresponding public key. Public key must be a valid point on G2 curve in an uncompressed format. Message must be a valid point on G1 curve in an uncompressed format. Signature must be a valid point on G1 curve in an uncompressed format.

_verify

function _verify(struct AltBn128.G2Point publicKey, struct AltBn128.G1Point message, struct AltBn128.G1Point signature) public view returns (bool)
