To lock this transaction do the following: To lock this transaction do the following:
1. Serialize `OP_ADD 99 OP_EQUAL` (`<serialized99Equal>`) then SHA-256 and RIPEMD-160 hash it (`<hashed99Equal>`). 1. Serialize `OP_ADD 99 OP_EQUAL` (`<serialized99Equal>`) then SHA-256 and RIPEMD-160 hash it (`<hashed99Equal>`).
a. OP_ADD = 0x93
b. 99 = 0x01, 0x63, the first to push one byte onto the stack, the second as the hex translation of 99
c. OP_EQUAL = 0x87
d. `<serialized99Equal>` = "93016387"
e. `<hashed99Equal>` = "3f58b4f7b14847a9083694b9b3b52a4cea2569ed"
2. Save `<serialized99Equal>` for future reference as the `redeemScript`. 2. Save `<serialized99Equal>` for future reference as the `redeemScript`.
3. Produce a P2SH locking script that includes the hashed script (`OP_HASH160 <hashed99Equal> OP_EQUAL`). 3. Produce a P2SH locking script that includes the hashed script (`OP_HASH160 <hashed99Equal> OP_EQUAL`).
4. Create a transaction using that `scriptPubKey`. 4. Create a transaction using that `scriptPubKey`.
