stage 1:

client send InitRequest (just {}) to server

stage 2:

server send to client base and desired compexity

stage 3:

client try to generate nonce, for which hash((base << 64 ) | nonce) & ((1 << treshold) - 1) == 0

stage 4:

server drops connection, if there is no answer for TIMEOUT_MS millis, or check response from client and send quotes (payload)

stage 5:

client recv payload and print it

Many have marked the speed with which Muad'Dib learned the necessities of
Arrakis. The Bene Gesserit, of course, know the basis of this speed. For the
others, we can say that Muad'Dib learned rapidly because his first training was
in how to learn. And the first lesson of all was the basic trust that he could
learn. It's shocking to find how many people do not believe they can learn, and
how many more believe learning to be difficult. Muad'Dib knew that every
experience carries its lesson.
    from "The Humanity of Muad'Dib" by the Princess Irulan
