In Wolfram Warptangent (Monero v0.10), a new fee structure was introduced, in addition to decreasing the minimum tx fee. What is the current fee structure?

Two weeks after the v3 fork, nominal fees will decrease from 0.01 monero/kB to 0.002 monero/kB. At the same time, the fee multipliers used for priority determination will change from x1, x2, x3 to x1, x20, x166. These numbers are chosen so that using x166 compensates a miner for the loss of block reward incurred by pushing the block size substantially over the median of the last N blocks. In simplewallet, those extra fee tiers are selected with set priority X, with X from 1 to 3, and those will map to the above multipliers for all subsequent transactions.


Previously, the fee structure was 0.01 XMR per kilobyte. Now it is 0.002 XMR per kilobyte. So if a transaction is 5 kb big, it will cost 0.002 * 5 = 0.01 XMR, whereas previously it would have cost 0.01 * 5 = 0.05 XMR.

    I was asking more about the priority fee multiplier structure than the min fee, not sure if that's taken effect yet. Sep 27, 2016 at 1:52

    Are these fixed values that will be changed every time there will be a new software release / major move in the value? Is the idea to have say a relatively constant $ cost per kb?
