| "can you demonstrate one?" Blockchain is just bookkeeping. I don't know, can you demonstrate a use case for accounting or book keeping? Up to now we always had to do accounting in books that can be cooked and have to be trusted. Blockchain is accounting with books that can't be cooked and don't have to be trusted. It has other problems which are real, but so what? Everything has some kind of problem. With blockchain the problem is if you go for convenience and use a centralizing key custodian, then someone else controls your keys and everything they protect, and if you don't, then it's too easy to lose your keys and everything they protected with no recovery. Well those are real problems but they are no different from the problems of using a plain database that can be copied, modified, hidden, stolen, has to be trusted even though you know you actually can't trust the owner, etc... |
Not really. It’s books that a couple people tediously agree on.
