How to create raw bitcoin transaction with multisig type of output scriptPubKey

Question

I need to send money in one transaction to 2 addresses so that any of them can spend it. In other words - I need to create same transaction as here https://www.blocktrail.com/BTC/tx/6e2c5b6b2a926a7da2415ae55c701e83d6e7bc46bad9bc23b5f9c7ef1ae26998 ( hex of raw transaction is

I need same result - array of several P2PKH addresses and multisig type.

But https://bitcoin.org/en/developer-reference#createrawtransaction method does not allow directly set array of addresses for 1 output in transaction - only 1 address.

I created transactions with P2SH address, which was created with createmultisig function:

user@workstation:/home/username$ bitcoin-cli createmultisig 1 '''["1BdxBor4JG76RKLAwJZfHC58fWbgidYukz","1MN3cT9Ro927h4kgpSZ5V7SfYjrwTysXv7"]''' { "address": "3Jc4v7eo9rptPj4277c9cCjgJmWSQmBiwj", "redeemScript": "512102f2221ec0e4baa45633a1f10d41cb199d943ec448368b90d9c7982095fd926ffa2102a9132ba9b227c62cf02deaff00e974fd9bfbe96ed1947d9bf8c7af40c5c22dd752ae" }

But in the result of json-rpc method getrawtransaction I see "scriptPubKey": { "asm":"OP_HASH160 b98a8e7f0375003d5537ff8489fcf9c4ad98f235 OP_EQUAL", "hex":"a914b98a8e7f0375003d5537ff8489fcf9c4ad98f23587", "reqSigs":1, "type":"scripthash", "addresses":["3Jc4v7eo9rptPj4277c9cCjgJmWSQmBiwj"] }

What I am doing wrong?

Answer 1

I try to provide a (partial) answer: I thin you are not doing anything wrong... there are two ways of creating multisig tx. The "old" way as with your link from blocktrail, and the "new" way as per your following text. The old way had two or three disadvantages: it bloats the blockchain from the beginning, the fees are high at the beginning, and it discloses the possible signer's pubkeys. In this case the 3 non compressed pubkeys have each 65 bytes, so 200 bytes on the blockchain...

The new multisig via a P2SH construct basically hashes the spending logic (also called the redeem script: 2 3 CHECKMULTISIG), and base58check encoded provides a "P2SH address" (beginning with a "3"). This hash is then only 20 Bytes long, non-reversible (you can't see which are the pubkeys), and the fee for bringing this tx to the blockchain remain low. Of course, at the very end, the spending this tx requires to disclose and pay the higher fees.

Unless you don't have a very, very specific use case, do you think it is impossible to use the newer logic? I found further description in Andreas book "Mastering Bitcoin" in Chapter 7, page 149ff - it is also online available.
