We move away from using the funding transaction id, as the introduction of RBF makes it such that a single channel may have many funding transaction id's over the course of its lifetime.
v1 lightning channels: one side funds a transaction to make an open, funds are all on their side
v2 lightning channels (dual-funded): both sides collaborate to make a transaction, funds can be in any amount on either side. it’s basically a mini coinjoin/payjoin onchain for every lightning channel that uses it
you can multifundchannels in CLN; if every peer uses v2 opens that will let you build basically your own decentralized coinjoin that results in channel opens 😎
no coordinator, all in one tx
add in liquidity ads and you can get multiple inbound channel capacity, again all in one tx with the payment for that liquidity being just more available inbound.
it’s a huge game changer on lightning’s onchain footprint
splicing builds on this and will let you do even more complicated liquidity movements in one transaction. move liquidity between channels, fund a new channel from an existing one, etc. All in one transaction
Lightning’s v2 era is coming!!
Waiting for 2.1
Carla on WBD called bitcoin protocol work "eating shit." This is what makes eating shit worth it.
Here we go. Thanks for sharing.
Go Nifty!

I'm pretty techy in general, even know a bit about lightning, but my brain power is very low atm
