Hello,

I have been researching about blockchains and stuff and it all seems like a big scam. It’s not sustainable and can be replaced by a simple database.

is there any legitimate use cases of blockchains or it is all just a big scam?

    How do you sync those copies? Whatever sync process you use could be abused to propagate wrong transactions into other banks unless you figure out a solution to the bizantine generals problems, other than a Blockchain I mean.

      Something similar to the way files (and bank transaction records) are modified on a drive. A first message indicating that a specific transaction is starting, a second message with the transaction, and a third message indicating the transaction is complete.

      If any message is not acknowledged, it can be resent (with an ID so it’s recognized as a duplicate), and if all else fails, flag a human.

      The system doesn’t need to be 100% accurate, just good enough that only a few humans are needed to fix the problems.

      The Byzantine Generals problem is only a problem if you need 100% certainty from both sides. If you’re willing to put up with 99.99% certainty, then network engineers have solved this problem many years ago.
