Has anyone used difficulty to get constant-dollar developer or node fees? Difficulty is exactly proportional to network hashrate, and network hashrate is closely proportional to coin price. Say a coin...

## Edit I made this article long and complicated, so let me try to summarize "how to identify the best algorithm": Normalize their "N" parameter until they all have the...

Masari deployed [my modification of Tom Harding's difficulty algorithm](https://github.com/zawy12/difficulty-algorithms/issues/3) on December 3, 2017 and it's a resounding success (so far). I follow 7 coins' difficulty performance closely, and it's the...

Best algorithm: **[WHM difficulty algorithm](https://github.com/zawy12/difficulty-algorithms/issues/3)** I've been careful to select the best N and adjustment factor (to get the correct average solvetime) for this algorithm. The next two algorithms are...

The following is a difficulty algorithm who's window is based on a time instead of blocks. I have not tested it and it probably has a symmetry problem that will...

This keeps a really smooth difficulty by defaulting to a large N, but switches to a smaller N if there is a sudden >3x increase or B or (median(TS[i],TS[i-1],TS[i-2]) -...

Difficulty performance of various coins

This shows the performance of 7 coins' difficulty algorithms for 3800 blocks. Notice in the additional posts below that Masari's with the new WHM N=60 is doing better than the...

Masari used Sumokoin's algo which is: ```next_D=avg(17 D) / (0.8*avg(17 ST) + 0.3*median(17 ST)``` ST=solvetimes. The 17 D and ST were 6 blocks behind most recent block. There is a...

The following are articles I plan to write (largely re-writing things that are already somewhere on GitHub. - [Best difficulty algorithms](https://github.com/zawy12/difficulty-algorithms/issues/1) - Performance Metrics - [Selecting N](https://github.com/zawy12/difficulty-algorithms/issues/14) - [Handling Bad...

This is a summary of issues that keep coming up. ### WTEMA is the only difficulty algorithm people should use Every PoW needs to just use WTEMA. It's simple and...
