I find it fascinating to watch as the crypto community gradually recapitulates the evolution of the existing financial regulation/structure. In this case, negative attestations are reimplementing liens / UCC filings (for business loans) and credit reports (for individuals). But without any plausible consumer rights recourse, of course. (Like for example your right to have errors on your credit report fixed.) It will be interesting to see if they can use zk-SNARKs to come up with a scheme that’s substantially better here. Another corollary of this observation is that crypto will recapitulate the evolution of privacy legislation too. As the OP notes these systems are going to struggle to comply with deletion requests under GDPR. And while many would buy the premise that financial regulations are not helpful to the public (I don’t personally buy that), I think privacy legislation is much more popular and clearly a case of hard-won consumer protection.
