});

const result = validator.authenticate(signatures);
// result: { temp_key_x, temp_key_y, verifier_name, verifier_id, ... }

Validate One-Time Signatures

const validator = new SignatureValidator({
  nodePubKeyX: "...",

const result = validator.authenticateOneTimeSignatures(signatures, {
  base64Encoded: true,
});
