You could easily generate a p2wsh address which encapsulates the correct rules. Payout would be controlled by an M-of-N group of "approvers", and require the party doing the work to sign as well to prevent collusion amongst the "approvers" to steal the funds. Something 14:27 < ademan[m]> like `and(pk(A),thresh(2, pk(B), pk(C), pk(D)))` Then, contributors could all send coins to this address, to be disbursed to the payee according to the conditions set out in some written proposal. *except of course* this is address reuse. I *think* that given the use case: a one time sweep of the address, and multisig, this is likely safe-ish in practice, but am I correct in assuming it's still considered vulnerable? 14:27 < ademan[m]> The alternative I can think of: input aggregation like described here: https://en.bitcoin.it/wiki/Contract#Example_3:_Assurance_contracts doesn't seem possible without asking the user to either install and trust some software that uses RPC (hopefully they use core!), or understand rawtransactions, is there a third option I'm missing? 14:28 < sipa> replace B,C,D with xpub paths? 14:28 < sipa> and A 14:29 < ademan[m]> It would actually be possible (but cumbersome) in core if you could get a psbt for an underfunded transaction when using coin control 14:29 < sipa> that doesn't really help much though, as the derivation is publicly known 14:29 < sipa> so it's not actually all that better than address reuse 15:00 -!- remote [~self@user/hackers] has quit [Ping timeout: 272 seconds] 15:03 -!- ghost43 [~ghost43@gateway/tor-sasl/ghost43] has quit [Remote host closed the connection] 15:03 -!- ghost43 [~ghost43@gateway/tor-sasl/ghost43] has joined #bitcoin-wizards 15:06 -!- ghost43 [~ghost43@gateway/tor-sasl/ghost43] has quit [Remote host closed the connection] 15:06 -!- ghost43 [~ghost43@gateway/tor-sasl/ghost43] has joined #bitcoin-wizards 15:18 -!- AaronvanW [~AaronvanW@user/AaronvanW] has quit [Quit: Leaving...] 15:25 -!- bitdex [~bitdex@gateway/tor-sasl/bitdex] has joined #bitcoin-wizards 15:51 -!- dllud [~dllud@136.138.62.94.rev.vodafone.pt] has quit [Read error: Connection reset by peer] 15:52 -!- dllud [~dllud@136.138.62.94.rev.vodafone.pt] has joined #bitcoin-wizards 15:52 -!- lukedashjr [~luke-jr@user/luke-jr] has joined #bitcoin-wizards 15:55 -!- luke-jr [~luke-jr@user/luke-jr] has quit [Ping timeout: 256 seconds] 15:55 -!- lukedashjr is now known as luke-jr 16:01 -!- ghost43 [~ghost43@gateway/tor-sasl/ghost43] has quit [Remote host closed the connection] 16:02 -!- ghost43 [~ghost43@gateway/tor-sasl/ghost43] has joined #bitcoin-wizards 16:09 -!- luke-jr [~luke-jr@user/luke-jr] has quit [Quit: ZNC -
