## Create a Raw Multisig ## Create a Raw Multisig
As discussed in [§10.2: Building the Structure of P2SH](10_2_Building_the_Structure_of_P2SH.md), multisigs are one of the standard Bitcoin transaction types. A transaction can be created with a locking script that uses the raw `OP_CHECKMULTISIG` command, and it will be accepted into a block. This is the classic methodology for using multisigs in Bitcoin. As discussed in [§10.1: Understanding the Foundation of P2SH](10_1_Understanding_the_Foundation_of_P2SH.md), multisigs are one of the standard Bitcoin transaction types. A transaction can be created with a locking script that uses the raw `OP_CHECKMULTISIG` command, and it will be accepted into a block. This is the classic methodology for using multisigs in Bitcoin.
As an example, we will revisit the multisig created in [§8.1](08_1_Sending_a_Transaction_to_a_Multisig.md) one final time and build a new locking script for it using this methodology. As you may recall, that was a 2-of-2 multisig built from `$address1` and `$address2`. As an example, we will revisit the multisig created in [§6.1](06_1_Sending_a_Transaction_to_a_Multisig.md) one final time and build a new locking script for it using this methodology. As you may recall, that was a 2-of-2 multisig built from `$address1` and `$address2`.
As as `OP_CHECKMULTISIG` locking script requires the "m" (`2`), the addresses, and the "n" (`2`), you could write the following `scriptPubKey`: As `OP_CHECKMULTISIG` locking script requires the "m" (`2`), the addresses, and the "n" (`2`), you could write the following `scriptPubKey`:
``` ```
2 $address1 $address2 2 OP_CHECKMULTISIG 2 $address1 $address2 2 OP_CHECKMULTISIG
