i’ll add a concrete example to this… i’ve described a startup i built in another comment but TLDR:

compliance obligations when protecting kids from sexual predators are difficult to prove: sexual abuse usually comes out 30 years later, so standard record keeping is pretty fraught… companies (like the company monitoring compliance - our startup for example) might not exists any more, paper gets lost, database formats become difficult or impossible to read

writing signed proof of compliance to the blockchain is a way of ensuring that an organisation was doing what they could at the time… how this is achieved is tricky for anyone but the source of record, but with blockchain it’s possible (described in the post)
