Message-ID: Gentlemen, The micropayment system that is LN today has some limitations in pathfinding with hops accommodating the needed liquidity with regards to larger amounts, where probability of success and the forward fee also needs to be accounted for in a total cost of attempt. Probability and cost for xx M sats will not today have any gain compared to go on-chain. If still in need and or requested to have tx in a near instantaneous settlement using LN regularly, one would have a setup of LN-Nodes in aggregate to facilitate tx with such profiles. If Lady Gaga would like to send 0.6 to Madonna in a LN tx for remuneration of a designer purse, for Us to be able to facilitate that : We would need to onboard them first ... If A would like to send 0.6 to B, in a non anticipated recurring flow, A would just go on-chain, or A would open a channel with --push amt to B, probability asserted and cost minimised. In an anticipated recurring flow, I repeat -one would have a setup of LN-Nodes in aggregate to facilitate liquidity in such a scenario, as I am sure Baller and Bird ++ other biz already do today. There is a proposal in changing the protocol to accommodate an algorithm to do pathfinding and spontaneously make larger payments possible in LN, where proposal fails directly in that it has a non real world scenario as argument. Calculating total cost in a 0.6 balance transfer involving a MPP split to 500 120K tx to use a hop sequence as a-b-c-d, would require 4000 ledger entries ? ( 2 at each node ) in 1002 LN-Nodes and the probability of success is ? ?, with a ppm fee forward cost > then what We in the real world would use and spend today. As an application developer wishing to use LN protocol pure and interoperable whole, I can see there are more pressing needs in refining existing protocol and implementations than spend wetware time on hypothetical non real world scenarios. Altho still amusing and stimulating as edutainment. Thank you /xraid
