pub const OP_CHECKMULTISIG: u8 = 0xae;Expand description
OP_CHECKMULTISIG - Compares the first signature against each public key until it finds an ECDSA match. Starting with the subsequent public key, it compares the second signature against each remaining public key until it finds an ECDSA match. The process is repeated until all signatures have been checked or not enough public keys remain to produce a successful result. All signatures need to match a public key. Because public keys are not checked again if they fail any signature comparison, signatures must be placed in the scriptSig using the same order as their corresponding public keys were placed in the scriptPubKey or script. If all signatures are valid, 1 is returned, 0 otherwise
