Can't they be used to link outputs across mixdepths since every time a taker uses a maker with a fidelity bond for an order they will know the fidelity bond, which does not change, and the outputs the maker uses to fill the order? 07:42 < belcher> that taker could just use the maker's irc nicknames, they only rarely change 07:43 < belcher> the fidelity bond UTXOs are not linked to the coinjoin, except by the taker and that taker already knows the mapping of inputs and outputs 08:38 -!- rojiro_ [~rojiro@gateway/tor-sasl/rojiro] has quit [Remote host closed the connection] 08:38 -!- rojiro_ [~rojiro@gateway/tor-sasl/rojiro] has joined #joinmarket 12:06 -!- RubenSomsen [sid301948@user/rubensomsen] has joined #joinmarket 14:18 -!- deafboy [quasselcor@cicolina.org] has quit [Quit: deafboy] 14:18 -!- deafboy [quasselcor@cicolina.org] has joined #joinmarket 15:23 < xyy> "that taker could just use the..." <- would it make sense to change the nickname more frequently, or does the disruption outweigh the benefits? 15:23 < xyy> I guess now with FB it's moot 15:24 < belcher> i dont really see why its a privacy problem, since the taker already knows everything 15:24 < belcher> remember takers know the full mapping of inputs to outputs in a coinjoin they make 15:25 < belcher> i suppose it might be a problem in some situations, so id rephrase and say its not a problem in practice 15:25 < xyy> what about takers who are not involved in the coinjoin ... what can they learn? 15:25 < belcher> they dont learn anything 15:25 < xyy> is there something they can learn over time without ever getting involved in that maker's coinjoins? 15:25 < belcher> they can just passively look at transactions on the blockchain like anyone else 15:25 < belcher> maybe they could learn something by watching the orderbook? i doubt it though 15:31 < xyy> I guess they could narrow down the variables that the maker publishes with noise added 15:31 < xyy> if they observe that maker's disclosures over a certain time period 15:34 < xyy> and if the identity of the maker doesn't change / the identities can be linked 15:36 < xyy> unclear if that's a problem 15:43 -!- Xeha [~Xeha@dynamic-82-220-88-142.ftth.solnet.ch] has quit [Ping timeout: 252 seconds] 16:22 -!- belcher [~belcher@user/belcher] has quit [Ping timeout: 252 seconds] 16:36 -!- belcher [~belcher@user/belcher] has joined #joinmarket 16:49 -!- Xeha [~Xeha@dynamic-82-220-88-142.ftth.solnet.ch] has joined #joinmarket 21:07 -!- bairen [~bairen@gateway/tor-sasl/bairen] has quit [Remote host closed the connection] 21:08 -!- bairen [~bairen@gateway/tor-sasl/bairen] has joined #joinmarket 21:38 -!- dodo [~dodo@user/dodo] has quit [Quit: dodo] 21:39 -!- dodo [~dodo@user/dodo] has joined #joinmarket --- Log closed Sun Oct 10 00:00:31 2021
