Until there is one actual viable application, everyone should question whether it's vaporware or not.

Please note that substantial C++ code that I wrote is in the XRP blockchain, so I'm not an idiot on these matters.

Nothing that NFTs claim they will eventually do, couldn't be done by 1970s technology 1000 times faster and cheaper.

To continue, please give any real application that isn't cryptocoins that cannot be done by a boring old Merkle tree without the incredibly expensive consensus phase.

The general response I get from the above paragraph is for people to say, "I don't understand what that is." This is rather like someone going on about car engines who doesn't know what a carburettor is...
