I had a similar idea a few years ago but decided to make it wholly objective. Basically, individual actors could publish cryptographic proof that they had engaged in a certain transaction with a certain party and reached a certain outcome, without necessarily disclosing the full details of the transaction. This information could then be analyzed and collected by those considering entering in to a transaction with that party, or perhaps paid agencies who acted as caches to do this for the general public.
