Dev Docs Correction: CHECKMULTISIG Requires Sigs In Same Order As PubKeys

Browse source

description, additional details, and references in other parts of the
text where we mention multisig. (Fixes #622)

list of secp256k1 signatures in the signature script must be prefaced with an extra value
(`OP_0`) which will be consumed but not used.
The signature script must provide signatures in the same order as the
corresponding public keys appear in the pubkey script or redeem
script. See the desciption in [`OP_CHECKMULTISIG`][op_checkmultisig]
for details.
