15:20 < Ylbam> was wondering if we could derive payment_hashes from an original preimage seed 15:20 < cdecker> Yep, do not reuse payment hashes, they are free money for relaying nodes 15:20 < Ylbam> to be able to send several payments after having been communicated only one parent payment_hash 15:21 < cdecker> There could be methods to generate a set of hashes and transfer them in a single invoice 15:21 < Ylbam> is it something doable? 15:21 < Ylbam> Does BIP32 or something similar could be used? 15:21 < cdecker> Probably, though it might not be trivial 15:22 < Ylbam> my usecase is a dice betting service, working on a PoC for fun 15:22 < cdecker> If we replace the hash/preimage with pubkey/privkey yes 15:22 < Ylbam> would like to be able to send multiple bet payments without having the user to send me multiple corresponding invoices 15:22 < cdecker> Hehe, sounds fun ^^ 15:22 < Ylbam> sounds like an interesting usecase indeed 15:23 < Ylbam> @roasbeef seems to be working on a fully trustless solution 15:23 < Ylbam> in my PoC we are still relying on an honest dice server 15:24 < cdecker> You could take a look at elkrem or shachains, maybe they work ^^ 15:24 < Ylbam> but bets are at least provably fair 15:24 < Ylbam> I'll have a look, thanks a lot for answering my questions :) 15:24 < cdecker> Yeah, nbeen trying to find a trustless version too, but so far no luck 15:24 < Ylbam> @roasbeef talked about ZKBoo AFAIR 15:25 < Ylbam> but it didn't seem trivial at all ;) 15:38 -!- jtimon [~quassel@c-73-189-35-88.hsd1.ca.comcast.net] has quit [Ping timeout: 255 seconds] 15:40 < adiabat> Ylbam: there's a trustless way to do it with guessing preiamge lenghts 15:40 < Ylbam> could you explain a bit please?
