Spending the transaction requires signatures from all the private keys corresponding to the public keys listed in the script. It's not actually necessary that a single person know all the private keys, but if you, an attacker, wanted to spend it without anyone else's cooperation, you would need all those private keys. (Depending on whether they have been used before, those private keys might also allow you to spend other, possibly single-signature transactions and steal some coins.) | |
| Jul 22, 2014 at 18:24 | comment | added | almel | @Nate Eldredge good answer, except you say "...spending the transaction requires you to know the private keys of the intended recipients." I think you meant to say something like "spending the transaction requires you to know the private keys of the addresses used to form the multisig address. If you knew the private keys of the intended recipients you would steal their bitcoins by transfering theose addresses' contents to your own wallet. I have a question of my own: How is the hash of the script the multisig address? You say this in the final large paragraph. | |
