  I think I have a decent technical understanding of how blockchains work, but I still sometimes have trouble understanding how exactly they would work for some proposed applications like this one. Could you please ellaborate? Correct me if I'm wrong, but I understand that the whole point of a blockchain is to update and maintain information in a distributed manner and in a trustless environment. In this case: - Could any person (who finds an appropriate nonce) update this blockchain with whatever information they want? - What information would be stored in it? - Doesn't it make more sense for this kind of data to be centralized rather than distributed? Unless the black box model you mentioned specifically needs a blockchain
