devs are in the process of making lightning 2.0 (layer 3)
its where you dont vault up funds into a channel. but instead deposit funds into a factory multisig
the factory then offchain creates channels below it in millisats.
so users cant broadcast, but can close session with the factory and so the factory aggregates the channel balances and recreates new channels to rebalance the channels.
thus even less onchain transactions as it wont require onchain broadcasts/settlement to close/reopen
THIS is exciting. Do you have any documentation you can share?
One of the biggest issues I have found with LN is the issue with locking funds up in a channel. I always thought this would be the main issue for many users. I am glad to see the LN devs are looking to improve on this model!!
