Is this not going to be able to be redeemed because it does not have a OP_y before the OP_CHECKMULTISIG?
Topic: When can you figure out an address from inside a transaction? (Read 962 times)
I found a transaction on testnet with the following scriptPubKey
Is this not going to be able to be redeemed because it does not have a OP_y before the OP_CHECKMULTISIG?

Thanks Danny (and achow101).
Do you know what the structure of a multisig output looks like (in OP codes)?
They look like this:Do you know what the structure of a multisig output looks like (in OP codes)?
Code:
OP_0... OP_y OP_CHECKMULTISIG
Or can you also get an address when the P2SH is:
Code:
... OP_CHECKMULTISIG
As achow101 has implied...
OP_CHECKMULTISIG is not a P2SH output.
It's a multisig output.
I suppose, if you want to, you could potentially convert each of the public keys from the multisig output into a separate address.

There are only two versions of address, '1' and '3' addresses. '1' is for P2PK and P2PKH outputs, and '3' for P2SH outputs. These three output types are the only standard output types for now.
You can represent anything you want as an address. You just have to create your own algorithm for generating the representation.
Really, it's only the P2PKH and the P2SH outputs that have a standard bitcoin address. Anything else (including P2PK) is non-standard and is up to the person doing the conversion to decide how they want to represent it.
It is common to represent a P2PK output as a version 1 address, but if you gave someone that version 1 address there are no wallets that would build such an output, and when the output was created it was NOT done with that address.
Thank you.
With regards to P2SH, is it only possible to get an address from the pattern:
Code:
OP_HASH160OP_EQUAL
Or can you also get an address when the P2SH is:
Code:
... OP_CHECKMULTISIG
Code:
OP_HASH160OP_EQUAl

I'm running through the blockchain (blk*.dat files), and I'm trying to get the addresses from inside each transaction.
So far I've made this diagram to show when I can get an address from a pattern of OP codes:
What other patterns of OP codes allow you to work out addresses?
