How does it work? I don’t have time to read the code, and the website/docs seem to be under construction.

Does it have the client do a bunch of SHA-256 hashes?

Yeah it's like hashcash. You have to try random numbers until you roll a hash with enough leading zeroes. Then you get a cookie (JWT I think) that's valid for a week.

SHA2 can run on ASICs and isn't memory-hard, so I'm hoping someone will add something tougher
