One interesting, and largely unexplored solution to the problem of distribution specifically (there are reasons why it cannot be so easily used for mining) is using tasks that are socially useful but require original human-driven creative effort and talent. For example, one can come up with a "proof of proof" currency that rewards players for coming up with mathematical proofs of certain theorems. There is no generic algorithm, aside from brute force, for proving theorems, and yet proofs of theorems are theoretically computationally easy to verify: one simply needs to write every step of the proof in a formal language, allowing the use of only one inference rule (eg. a + b = b + a or a * (b + c) = a * b + a * c but not a * (b + c) = a * c + b * a) between each step, and having a program verify the correctness of the inferences at each step.
I just read the above and was wondering if anyone could explain how this would work in the real world
How would a proof of proof currency look like and has it ever been implemented?
