> Distributed systems where you own the data and there's no single point of failure. If I encrypt my 1TB of the data I have at home and put the copies on AWS, GCP, and Azure, there's also no single point of failure and I own the data. Still, blockchain is a solution looking for a problem. I can own data without relying on a worldwide self-settling ledger. There's the "shutdown test" for the actual immediate utility value of anything worldwide. If we hypothetically manage to shutdown Bitcoin and all the other blockchains, what would be the overall effect to the world? Some big and small speculators losing assets and no actual loss of value (but less carbon emissions, so maybe increase of value?). On the other hand, shutdown stock exchanges, SWIFT systems, electricity, internet in general - big turmoil.
