OP_CHECKMULTISIG​

▪ Static Readonly OP_CHECKMULTISIG: OpCodeType

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 redeemScript. If all signatures are valid, 1 is returned, 0 otherwise. Due to a bug, an extra unused value (x) is removed from the stack. Script spenders must account for this by adding a junk value (typically zero) to the stack.

The signature used by [OP_CHECKSIG][https://wiki.bitcoinsv.io/index.php/OP_CHECKSIG](https://wiki.bitcoinsv.io/index.php/OP_CHECKSIG) must be a valid signature for this hash and public key. If it is, 1 is returned, 0 otherwise.

OP_RETURN​

▪ Static Readonly OP_RETURN: OpCodeType

OP_RETURN can also be used to create "False Return" outputs with a scriptPubKey consisting of OP_FALSE OP_RETURN followed by data. Such outputs are provably unspendable and should be given a value of zero Satoshis. These outputs can be pruned from storage in the UTXO set, reducing its size. Currently the BitcoinSV network supports multiple FALSE RETURN outputs in a given transaction with each one capable of holding up to 100kB of data. After the Genesis upgrade in 2020 miners will be free to mine transactions containing FALSE RETURN outputs of any size.
