Hey, there’s something I’m curious about. I’ve been examining the transactions since v15 fork, and there are a lot of exactly repeated values in the _absolute_ fee, not weight-adjusted.

Took a while to figure out what was going on: they are generated from the form `fee = intercept + k * increment` where all values are integers. Furthermore, there are numerous (intercept, increment) generators.

Below I’ll paste two plots, one with raw data, and one with transactions exhibiting this characteristic from the first two generators I discovered towards the high end of the data: (intercept: 6124000000, increment: 40000000) and (intercept: 31720000000, increment: 13580000000)

So far I’ve identified 6 generators: (6124000000, 40000000), (31720000000, 13580000000), (122560000, 80000), (158600000, 1800000), (226500000, 1800000), (709760000, 320000)

I can’t for the life of me figure out the meaning of these values or any higher order pattern in how the generators are sampled/created/whatever

Any ideas? Is this core wallet behavior?

The two generators in the below plot account for 14,084 transactions. When I count all 6 known generators, it’s 1,377,606 transactions (34%) since v15.

I'm brushing up on the current fee algo, maybe this is how wallet2 does it?

Ah here we go, this jives right? github.com/monero-project/monero/bl…1f/src/wallet/wallet2.cpp#L303-L308

🤔

No wait, hmm. I'm not sure

Have been poking more at the data set, I think this is fine (normal wallet behavior)
