Similar to LN but you don't get instant payments with liquid. Also not many people/businesses accept it.

I like the idea of using liquid for smaller "change" on chain. For example if a phone costs 950k sats, I spend a 1m UTXO & peg out the 50k sat change.

Repeat and after many times you can consolidate & peg back into on chain.

I guess you could do the same with LN too
