The refutation of all blockchains

Paraphrasing Irenaeus, here is a great video I discovered almost by mistake, which I think both highlights the distinction between virtual and real and kind of ends the discussion on the possibility of blockchains being of any use on authenticating anything that is not virtual.

So, in the wise words of James Hoffmann (segment starts at 00:07:46.280)

“Ooh, an issue with transparency. That’s a problem that the blockchain could solve.” No, no, you can still submit false, fraudulent information to the blockchain. And all you’re doing is writing with a very permanent, very wasteful marker into the ledger. In fact, I’d argue that it would probably enable fraud by giving a kind of veneer of authenticity to a fraudulent product. So please, no blockchain.
