Im trying to understand the funding transaction for a channel on the lightning network. I am wondering how the input looks like to the funding transaction. Does it require In_{Alice}(tx_{id}, tx_{index},redeem_script) and In_{Bob}(tx_{id}, tx_{index}, redeem_script) as inputs to the transaction or do you just see the first commitment transactions (like Ca1, C1b) from the multisig and and ensure they are valid then asynchronously submit funds to the multisig address? [0] just shows the output format as the multisig.
