08:48:25 <sech1> Does the current decoy selection algorithm single out coinbase (miner reward) transactions?
08:52:22 <jberman[m]> No, but by factoring in block density when selecting an output, the algorithm is less likely to select coinbase outputs. For example, if you have 3 blocks in a row, block 0 only has a coinbase tx, block 1 is extremely dense, and block 2 only has a coinbase tx again, then the algorithm would pick up more outputs from block 1 than it does from blocks 0 and 2. So coinbase tx's don't carry as much weight with this approach
08:53:09 <sech1> Anyway, coinbase unlock time is 60 blocks, so if the algorithm selects coinbase younger that this...
08:54:36 <sech1> I found the relevant piece of code in the output selection: https://github.com/monero-project/monero/blob/master/src/wallet/wallet2.cpp#L8294
08:54:40 <sech1> so it looks like it's handled
08:55:49 <sech1> comment on the line above suggests it's explicitly handled
08:57:41 <jberman[m]> Also it won't add locked outputs cuz of this: https://github.com/monero-project/monero/blob/master/src/wallet/wallet2.cpp#L7978-L7981
09:01:48 <sech1> "and the output was originally created in a block that has fewer than 100 outputs total in it"
09:01:57 <sech1> recent transaction spike kind of fixes this :D
09:02:51 <jberman[m]> haha yes! it does help was thinking the same
09:03:28 <sech1> This bug and FloodXMR attack don't work well together too...
22:12:54 <atoc> hi
22:19:05 <atoc> are there still regular research meetings?
22:20:49 <UkoeHB> no
22:21:04 <atoc> I see :(
22:21:54 <UkoeHB> however we can set up a meeting if there is something to discuss
22:22:24 <atoc> cool, yeah perhaps that would be nice based off the issues you sent me
22:25:39 <atoc> could try my hand at a PoC for this: https://github.com/monero-project/research-lab/issues/84
22:26:05 <UkoeHB> hmm what do you want to discuss in regards to those? (MRL #70, #84, repo #6456 for context)
22:26:14 <UkoeHB> ah sweet :)
22:26:46 <UkoeHB> TheCharlatan: started on a PoC, not sure how for he got
22:26:50 <UkoeHB> far*
22:26:54 <atoc> need to familiarize myself with Triptych though
22:27:04 <atoc> cool, will be nice to touch base with him
22:27:39 <UkoeHB> #84 is agnostic to the tx protocol, it just spits out a list of on-chain indices of arbitrary size
22:28:38 <atoc> i see
22:31:58 <atoc> definitely seems a good amount of research has been done here including thoughts on what binning algo to use
22:32:28 <atoc> there is code as well so yeah maybe seeing the state of this project would be nice
