Go learn cryptography.
It isn't me you need to sell this idea. It's the universe of potential adopters.
They are not interested in cryptography and have no intentions of "learning" it. Thats why - in the absence of a trusted third party - you need public consensus to assert the veracity of any monetary medium.
Look, you're quite honestly...clueless on the concept of fungibility. It looks as when you describe "opaque" blockchains like Monero's, you think of a brick wall or a black hole. In case you didn't know, that's not what it is. By Opaque, it means that transactions done between sender and receiver are unable to be connected to each other. So the money can be seen, but the beginning and end destinations cannot i.e, you can see just money, nothing else but money moving back and forth.
There goes your entire theory on "invisible blockchains" down the garbage.
he is one of the most despicable trolls in this forum he mask himself as retarded clueless because he like being called one, dashtards like to eat shit.
