Networked payment channels could be a great supplement to Bitcoin. They're useful for very small microtxs (on the order of <1cent), especially recurring txs, e.g. paying for pageviews.
Even with the very low fees we now have on BCH, there is no need to do EVERYTHING on-chain. Very small txs are impractical even with 1 sat/B fees.Imagine the LN, if nobody ever dreamed of using it for moving more than a couple of cents. There would be no liquidity issues, ever. Anyone with $10 could be a "liquidity provider"...High-degree, high-liquidity hubs would be far more decentralized. You wouldn't need watchtowers, since the risk of channel theft would be meaningless when channels contain just cents.Now couple that with low on-chain fees, so channels could be opened and closed much more easily and frequently, and the risk/liquidity barriers become quite negligible.LN has limited use-cases, but is not inherently flawed. I hope we will have it on BCH one day, because here it can actually work!
