A little bit ago some asked a question about why the hate of the blockchain, and that got me thinking if there even was a legitimate use case where the blockchain would be beneficial, but I couldn’t think of one outside maybe some sort of decentralized bank, but before I knew I was thinking it would instantly turn into some crypto scheme and strapped it, because crypto currencies are a scam on every level – and no they aren’t private or secret as some think either.
So I wanted to ask the community. Instead of using the blockchain for crypto, is there a better use where the blockchain could benefit society?
I’m going to go ahead and refute this claim.
Blockchains can be used to affect the physical world because blockchains can be used to transmit information. One example would be if the result of a blockchain transaction is sharing important information with a user, say a password, account number, or access token.
But there’s also the more obvious case, you can use financial blockchains to send money. If a system is designed to work with that currency, then it will presumably work with that currency. You could for instance design a vending machine to take Bitcoin, if it receives a certain amount of currency to a certain address, it dispenses a snack. Yes, there is an authority that manages this vending machine, but that’s unavoidable in any case. No matter what the scenario is, someone needs to own the machine and manage maintenance and supply for it.
