We've reached peak buzzword for blockchain in the last 6 months. It'll balance our national debt, cure cancer, and make everyone happy according to all the con artists, errr, sales people pitching it as the be all end all.
In a 256 bit hash? I'd love to know. Block chain can verify data - that is it. Tired of dipshits selling the latest buzz word when they have no idea what it is. Block chain is ledger, not a fucking database.

I get dumping documents from government agencies. Though, their motives are a bit bizarre at times. Disclosing hundreds of thousands of addresses of private citizens? What does that help?

Oh that is right, Wikipedia believes they can be opaque in operation, not transparent like they expect everyone else to be.
