You know that Bitcoin Scripts can be used to control the redemption of UTXOs. The next step is creating Scripts of your own ... but that requires a very specific techniques.

_What is a redeemScript?_ Each P2SH transaction carries the fingerprint of a hidden locking script within it as a 20-byte hash. When a P2SH transaction is redeemed, the full (unhashed) `redeemScript` is included as part of the `scriptSig`. Bitcoin will make sure the `redeemScript` matches the hash; then it actually runs the `redeemScript` to see if the funds can be spent (or not).
One of the interesting elements of P2SH transactions is that neither the sender nor the Blockchain actually knows what the `redeemScript` is! A sender just sends to a standardized P2SH addressesd marked with a "2" prefix and they don't worry about how the recipient is going to retrieve the funds at the end.

> **TESTNET vs MAINNET:** Reminder: on testnet, the prefix for P2SH addresses is `2`, while on mainnet, it's `3`.
