creates a bloom filter of all their utxos, the taker compares every bloom filter against every other 17:55 < belcher> remember that if two bloom filters dont match there is for sure no overlap, if they do match there is a false positive rate, so we set the false positive rate to be not very large 17:56 < belcher> trouble with that is someone could use the bloom filter on the entire utxo set and find all the maker's utxos + some false positives 17:57 < belcher> but in terms of data transferred it would be great, a fixed size regardless of wallet size 18:04 < belcher> hmm... what if instead of adding utxos to the bloom filter, we added podle commitments... then theres the same benefit of a fixed data size but adversaries cant use the bloom filter to get a list of matching UTXOs 18:14 < belcher> an issue might be can bloom filters be faked after the fact, like is it possible to come up with another podle hash that still matches the advertised bloom filter, from reading the algorithm im guessing yes 18:15 < belcher> unless you use cryptographically-secure hash functions like sha256 and somehow require them to bruteforce sha256 in order to find another podle that still flips all the right bits 18:31 < belcher> then theres a possible DOS issue because calculating the bloom filter might require lots of CPU, that will have to be worked out 18:43 -!- Giszmo [~leo@pc-240-13-215-201.cm.vtr.net] has quit [Quit: Leaving.] 19:02 < belcher> hmm another problem with that is a DOSing maker could send a bloom filter with all 1s that matches with everything, then the taker would ban it and everyone else 19:05 < belcher> in the original podle proposal the taker can ban the second time it sees a podle hash.. but with bloom filters theres no ordering like that so i think the only way is to ban both makers 20:23 -!- HostFat [~HostFat@host141-180-dynamic.249-95-r.retail.telecomitalia.it] has joined #joinmarket 21:08 -!- cluelessperson
