[Lightning-dev] SegWit and LN

[Johan Torås Halseth]

Hi,
Before you can safely broadcast the funding transaction, the two parties involved in a channel must have signed a commitment transaction spending the output from the funding transaction. Without segwit, the funding transaction can be malleated, leaving the commitment transaction invalid, and funds locked up if one of the parties stops cooperating.

Cheers, Johan

Why is SegWit required for LN? If we wait for the funding transaction to be confirmed , we can then safely create and update unconfirmed commitment transactions...
I don't see how SegWit is important here... Am I missing something?
