12:38 < openoms> Active day today for JM
12:38 < openoms> To gauge the activity during this low fee period I have run the 
12:38 < openoms> snicker-finder -j 
12:38 < openoms> for the last 144 blocks (~1day)
12:38 < openoms> pretty impressive (with surely some false positives)
12:38 < openoms> TX list:
12:38 < openoms> https://pastebin.com/raw/dJkSBhDG
12:38 < openoms> transaction details with bitcoin-scripts checktransaction.sh:
12:38 < openoms> https://pastebin.com/raw/6J9c4Wp2
12:48 < waxwing> openoms, what's the count there? looks similar to what i usually find, around 30 / 24hrs?
12:49 < waxwing> although like you say high fees brings it down for sure
12:49 < openoms> 68 /144 blocks ;)
12:51 < waxwing> wait something's off here
12:51 < waxwing> 9ba8b9050a79a14e9bdf1c9fa89cbf17d4b0fd48a98a4a19ed9f760384b1e5f1 doesn't fit is_jm_tx() does it?
12:52 < openoms> yes, that's an outlier
12:52 < openoms> look like  a big consolidation to equal amounts, but no change outputs
12:52 < waxwing> we can pick up false positives but non-cj-outs should be = n or n-1 with n = coinjoin outs
12:52 < openoms> a "fake coinjoin"
12:53 < waxwing> yeah but i don't get it, it shouldn't be output by the algo? is it a bug?
12:53 < waxwing> let me run on that block
12:53 < openoms> 682653
12:54 < waxwing> damn yeah that's a bug. i must have done something very dumb here. checking.
12:56 < waxwing> openoms, oh! i didn't look carefully enough.
12:56 < waxwing> half of them are different values.
12:57 < waxwing> so yeah that's jsut a false positive, not avoidable unless we used a slightly more sophisticated algo (which is certainly possible)
13:00 < openoms> oh right I didn't spot that 1 sat difference either
13:01 < openoms> 5c119d26c318c6ba477f9baf9134e6ca1bf2a4682875ea2733acdb5a25d492cd is the same kind with fewer outputs
13:01 < waxwing> yeah no worries, we always tend to have a few here and there, not too many i think
13:02 < waxwing> thanks for running that parsing script, it's interesting to scroll through them.
13:03 < openoms> yes props to @kristapsk, it is a really good output to look at coinjoins. Will be part of the joininbox now
13:04 < openoms> very fast also
13:05 < waxwing> really? i found at least a few seconds of CPU bound for each block, so running a whole day takes, what, 3-5 minutes on this (fairly high end) laptop?
13:05 < openoms> I meant the parsing from the txindex
13:05 < openoms> yes, I was scanning on an RPi4
13:06 < waxwing> oh that, right
13:06 < openoms> took like 30 mins
13:06 < waxwing> sounds about right yeah. python is pretty slow and this is not even an attempt to be optimised.
13:06 < waxwing> not much reason for people to run it themselves on their RPi though?
13:07 < openoms> well no, buy why not. those scripts can run on anything
13:08 < waxwing> 1c25869e34b59e919b11e631f78b02441b686d0fdfd2c6dc347a30b4965cbb93 is a weird one. standard JM structure but one OP_RETURN in place of change.
13:08 < waxwing> ah well, also has mixed inputs. something else entirely ofc.
