and their implications 11:57 < roasbeef> but also, a way to do probabilistic microypayments within channels 11:57 < roasbeef> so, Alice sends Bob 1 satoshi with a 50% chance of Bob being able to add the payment to his next state 11:58 < roasbeef> he calls it PILPPs, or "Pre-Image Length Probablisitc Payments" 12:01 < cryptocronus> thanks for sharing, very interesting 12:01 < roasbeef> in the 50% example, Bob needs to guess whether alice's pre-image has a length of 20 or 21 bytes. he commits to a decision within the channel, rescinding his stake in the opposite scenario 12:02 < cryptocronus> he’s proposing as a way to send subsatoshi payments? only really works of total amount will eventually be over 1 satoshi though, right? 12:02 < roasbeef> well you can do sub-satoshi between end points, rounding up or down once you settle 12:02 < roasbeef> but this allows you to send x satoshi in expectation 12:03 < roasbeef> so 1 satoshi with a 5% chance or 0.05 satoshi 12:03 < roasbeef> it's probabilistic, bob needs to guess the pre-image length 12:03 < roasbeef> you can add more possible lengths to give bob a better chance 12:06 < cryptocronus> got it, is this the only info out there about this idea? 12:07 < roasbeef> yeah, this is the first time he's spoken of it publicly 12:08 < roasbeef> well, there have been other schemes for PP proposed in the past 12:09 < roasbeef> this scheme is designed to operate within channels 12:10 < roasbeef> one could switch over their regular channel to this probabilitic state at any time (both endpoints need to agree ofc) 12:13 < cryptocronus> what’s a potential use case for probabilstic payment channels? 12:18 -!- shangzhou [uid156782@gateway/web/irccloud.com/x-fzyeslfagfxmzrdy] has joined #lightning-dev 12:25 < cryptocronus>

alice should _maybe_ pay bob, etc 12:31 < roasbeef> cryptocronus: yeah there are tests in the various sub-packages, you'll need my segwit branches for btcutil, btcd, and btcwallet to build it all atm though 12:31 < cryptocronus> yeah I noticed it was failing earlier 12:31 < roasbeef> the codebase is in an intermdiate state atm, where everything is moving over to use segwitty stuff 12:31 < cryptocronus> yeah think that’s mentioned in the readme 12:31 < cryptocronus> or somewhere at least 12:32 < roasbeef> so it builds for us locally, but you'll need to do a bit of git leg work to get it to build :p 12:32 < roasbeef> it'll be resolved soon though 12:32 -!- wraithm [~textual@24-148-50-13.c3-0.mart-ubr1.chi-mart.il.cable.rcn.com] has joined #lightning-dev 12:33 < cryptocronus> got it
