well, I think this is actually a problem (an insoluble one)

attesting what your equipment was when mining a block is trivial. Proving it is not, and I'm not sure how you could achieve it.

Any scheme used whereby the miner or the manufacturer of the mining unit certifies what spec of machine was used could be manipulated. Same goes for the location; using all kinds of IP proxy rules out determining origin using IP addresses. And the algorithm used to mine the blocks is entirely generic, the concept would not work if that were not true.


so, yes, it's a strange idea.
