The reason to use a blockchain  is because you&#x27;re locked out of service in the incumbent models. That means : gambling, drugs, sometimes porn, and capital flight. That&#x27;s why you use a blockchain. (And IMO, that&#x27;s what makes them so cool)<p>Otherwise - Blockchains totally suck at everything, and these private-blockchains&#x2F;blockchains without energy are completely inane and stupid
