| OP_CHECKSIG | 172 | 0xac | sig pubkey | true / false | The last byte (=sighash type) of the signature is removed. The sighash for this input is calculated based on the sighash type. The truncated signature used by OP_CHECKSIG must be a valid ECDSA or Schnorr signature for this hash and public key. If it is valid, 1 is returned, if it is empty, 0 is returned, otherwise the operation fails. | | OP_CHECKSIG | 172 | 0xac | sig pubkey | true / false | The last byte (=sighash type) of the signature is removed.
