@holiman @karalabe I tried to compare progpow verification results with https://github.com/chfast/ethash.
Single Ethash verification with the best currently available compiler is 0.9 ms.
The progpow implementation was done in this fork: https://github.com/ifdefelse/proghash/commit/dc8e918aa5cf68da0b6dc049634bde596170c14c#diff-551b1d6ef147e694c203c6e9a6dacbf7R521 but does not seem to work. At least they did not update the unit tests.
The same benchmark shows absurd 1.3 us.

We will be having someone who has ran new benchmarks for EIP 1108: Reduce alt_bn128 precompile gas costs.
We will also be having the team behind ProgPoW on the call so we can all sync up with what various people have been doing to test, benchmark, and otherwise explore it.
Please look over EIP 1108 and think of any questions you have for the ProgPoW team.
