## Understand How Multisigs Work ## Understand How Multisigs Work
In a typical P2PKH or SegWit transaction, bitcoins are sent to an address based on your public key, which in turn means that the related private key is required to unlock the transaction, solving the cryptographic puzzle and allowing you to reuse the funds. But what if you could instead lock a transaction with _multiple_ private keys? This would effectively allow funds to be sent to a group of people, where those people all have to agree to reuse the funds.

To create a multisignature address, you must first ready the addresses that the multisig will combine. Best practice suggests that you always create new addresses. This means that the participants will each run the `getnewaddress` command on their own machine: To create a multisignature address, you must first ready the addresses that the multisig will combine. Best practice suggests that you always create new addresses. This means that the participants will each run the `getnewaddress` command on their own machine:
``` ```
machine1$ address1=$(bitcoin-cli getnewaddress) machine1$ address1=$(bitcoin-cli getnewaddress)

Afterwards, one of the recipients (or perhaps some third party) will need to combine the addresses. Afterwards, one of the recipients (or perhaps some third party) will need to combine the addresses.
