Hi,
I have some money on NiceHash that I used for personal testing. I could throw some power at you.
After registering I never got an email and can't login without verifying my email address. You should check this out.
And also during the registration my token expired (less than 2-3 min), this was a bit annoying.
Are you using an already existing solution, because I'm sure I saw this web interface before.
Or are you implementing the backend and protocol from scratch? I just finished implementing GBT and stratum servers, but now I'm thinking of rewriting both with an unified interface. Because the documentation is all over the place and some of the extension are not well defined maybe we can compare notes on it
How much of stratum do you intend to support?
Do you have any testing with different miners and how well they work with your implementation?
