Note: it is possible that some relevant information may be missing from this summary; read the full log file for the complete, unedited discussion.
(1.1) on Seraphis11:
UkoeHB implemented binned reference sets and plans to work on the 16/2 jamtis address index discussion/possible implementation, then discretized fees
(1.2) on statistical analysis:
mj-xmr reported progress with the decoy selection algo analysis12, having summarized both the results and the strategy, and is planning to perform statistical analysis with Rucknium and jberman
mj-xmr mentioned the next (parallel) task of simulating the behavior of the system (fee and block size) in case of a sudden increase of transactions
Rucknium is working on estimating the effect (if any) of Minexmr’s increase in its pool fee from 1.0% to 1.1% on April 1st13
(1.3) on view tags and security:
jberman added support for view tags to the block explorer + monero-lws, helped add support for view tags to monero-python, and helped patch a vulnerability reported by kayabaNerve14
(2) Larger JAMTIS15 address tags (and address indices)
UkoeHB explained the address tag’s MAC and how increasing the size from 8 -> 18 will increase the blowfish ciphers from 1 to 3, but increasing the mac from 1 -> 2 bytes will reduce the cost of filter-failures by 1/256
jberman pointed out that 10 bytes per output would probably be more significant if the idea to have all tx’s use 16 outputs was implemented16
UkoeHB mentioned plans to do performance tests comparing 7/1 vs 16/2 jamtis address tags (size in bytes)
(3) Ending comments
cryptogrampy mentioned HotShop17
selsta was looking for someone to do an updated multisig writeup of the cryptography that should help the next audit (preferably before the launch of Haveno)
Rucknium suggested MAGIC18 could help fund the writeup and audit, and pinged coinstudent2048
jberman pinged dangerousfreedom for the task
Let me know if you find this kind of report helpful. If not, I will redirect time spent on this to other tasks.
