Now note that the way we managed this multi-sig was that we generated a PSBT with the correct UTXOs, where data was held in the wallets of both systems, then we allowed both of the users to process that PSBT on their own, adding UTXOs and signatures. As a result, we have two PSBTs each of which contain one signature and not the other. That wouldn't work in the classic multi-sig scenario, because all the signatures have to be sequential. Here, instead, we can make use of the Combiner role to mush those together.

Now note that we managed this multi-sig by generating a totally unsigned PSBT with the correct UTXOs, then we allowed each of the users to process that PSBT on their own, adding UTXOs and signatures. As a result, we have two PSBTs each of which contain one signature and not the other. That wouldn't work in the classic multi-sig scenario, because all the signatures have to be sequential. Here, instead, we can make use of the Combiner role to mush those together.

|

We again go to either machine, and make sure we have both PSBTs in variables, then we combine them:

Obviously, there wasn't a big improvement in using this method over multiply signing a transaction for a 2-of-2 multisig when everyone was using `bitcoin-cli`. We could have passed a raw transaction with partial signatures from one user to the other just as easily as that PSBT. But there nonetheless are big advantages to this methodology. First of all, it's platform independent. As long as everyone is using a service that supports Bitcoin Core 0.17, they'll all be able to sign this transaction, which isn't true when multi-sigs are being passed around. But more notably, it's a lot more scalable. Consider a 3-of-5 multisig. Under the old methodology it would have to passed from person to person, greatly increasing the problems if any single link in the chain breaks. Here, other users just have to send the PSBTs back to the Creator, and as soon as she has enough, she can generate the final transaction.
