You're technically right. It is not the problem of the Blockchain technology. Once something is persisted in the Blockchain you can (depending on the concrete implementation) be sure that it cannot be changed without the original owner's private key. I feel however that the whole "Blockchain Startup Universe" always comes up with the same bullshit claims. It usually goes like this: "Here is a difficult problem. To solve that problem we use Blockchain. The End." No one really explains how Blockchain is so much better at solving this than a regular database. But everyone just believes it is. So far I have not heard a satisfying explanation on how anyone will securely verify that a physical object/subject is indeed this one particular hash on the Blockchain. You will always need a third party to verify this. And then I wonder: If you need a trusted third party anyway, why do you need a Blockchain in the first place?

You're wrong to claim this. The "whole" blockchain startup universe is not coming up with bullshit claims. It's the bullshit portion of the blockchain startup universe that is doing this. The rest of us understand what we're dealing with and why it's novel. Perhaps you've only encountered bullshit claims about blockchain. Does that mean that hash chains are bullshit? No, we've been using them for years to power git. Oh, then does it mean that distributed conflict resolution schemes are bullshit? Nope, we've been using them for years with replicated databases. So then why do these things suddenly become bullshit when put them together? Beats me. Ask the haters. > So far I have not heard a satisfying explanation on how anyone will securely verify that a physical object/subject is indeed this one particular hash on the Blockchain. Why does that need to be done? That's not universally accepted as a problem that every blockchain company is trying to solve.
