Basic idea of proof-of-work.
- I want to prove that I did some amount of computation for ID XYZ.
- I hash XYZ + a counter. I count the number of leading 0 bits in the hash.
- If the number of 0 bits is greater than the difficulty, I am done.
- Otherwise, I increment the counter and try again.
One of the earlier examples of proof-of-work is Hashcash.
