In vout[0], there are two address("1AJbsFZ64EpEfS5UAjAfcUG8pH8Jn3rn1F", "1A8JiWcwvpY7tAopUkSnGuEYHmzGYfZPiq") got value 0.01000000, but which address gets the money?

[domob]

I would say "neither of those" gets the money, or maybe "both".  Since this seems to be a "1 of 1" multisig (according to blockchain.info), it means that either owner of one of those addresses can spend the 0.01 BTC (think: "whoever comes first").  Where the money is sent in this case is decided by the one spending it.

[bluemeanie1]

Seems a lot of people don't understand what a multisig transaction is.

It requires 2+ crypto keys to unlock the transaction and the output can then be put into any address the owners of those two keys wish.

as far as I know, no wallets will show this particular transaction as part of the balance for either address.

so in that sense, it's in a special JOINT ACCOUNT.  It might be possible to make a special kind of wallet app that can show the balance of such a joint account(perhaps one already exists), however this balance cannot be spent without BOTH private keys.

so what's the difference between p2sh and multisig?

[kjj]

In P2SH, there are two scripts.  The first script is a stub that makes other nodes recognize it as a P2SH script, and it includes the hash of the second script.  The second script can be anything, and it isn't revealed until the transaction is redeemed.  The hash of the revealed script must match the hash embedded in the stub.

Multisig is just a special script that has an instruction that verifies that at least M-of-N signatures are present.  This script can be in a normal transaction, or it can be in a P2SH transaction.

The stock client understands multisig via P2SH.  There are commands to create P2SH multisig addresses, and the client will understand them correctly.  If the client knows the P2SH address in question, and knows enough of the keys to redeem it, then the transaction will show up in listunspent, and the value will be calculated in your wallet balance, etc.

They all share some coin, P2SH is just one address(generated from multi public key) with redeemScript, Multisig has at least one address.
The coin which they shared is not belong to any one of these addresses.
To spend the coin, they all need at least one private key to sign.
Use command "#bitcoind gettxout xxxxx n" can find them before spend.

I think they the same thing, just looks different. P2SH looks more simple than multisig.

Thank for this good explanation, however I don't understand a thing in the last paragraph: if the client knows the P2SH address, it knows the hash of the script but doesn't know the script itself, so isn't able to determine if it has enough of the keys to redeem it, therefore it can't appear in listunspent etc. Now, is this correct or am I overseeing something?

Knowing the script is what I mean by knowing the address.

The node doesn't try every key it has against every transaction it sees to see if it can redeem it, it cheats.  It stores something called the scriptPubKey and uses that to look up secrets.  The secrets are usually private keys, but in this case, it is the redemption script.

Aha this was my missing bit. Thanks again.
