"blockchain" not bitcoin
what a surprise that corporations, well known for the corruption of their long chains of command and toxic psychology, benefit from blockchains to protect their databases, not an interesting or valuable use case nor something that really couldn't be fixed by abolishing LLCs entirely as being an abuse of the common wealth of people living nearby each other
yes, actually, you know since blockchains were invented (in the early days of distributed databases, and the inception of the entire field of distributed systems) users of it have profited from the accuracy and redundancy of the information by using hashes to chain transactions together, this was already a thing at least in the mid 90s, the blockchain is the useful thding, because it lets you make sure that nobody can tamper with the record in one area without it being discoverable, and correctable, indeed, ultimately it is just an error correction system and really salient to the use cases hashes as fingerprints and signatures as authorities
the only other one that stood out was property registries, but that is an example of where the court has adopted this as a notarization standard, good luck getting that use case to happen without cooperation of the court you must adjudicate any conflicts at
not gonna help you for those cases where the court doesn't recognise it and good luck getting it to be recognised as case law and even better luck getting it to be legistlated
