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?

    I’m not sure I follow how (de)centralisation can be a different concept from blockchains when the definition of a blockchain is something like a ledger-like data structure which is immutable, decentralised and distributed.

    Meanwhile with git, one user can unilaterally change the history by hard resetting and force pushing; then the other “nodes” just have to accept the changes.

      Idk where you got that definition… a block chain is just a chain of blocks…

      If someone unilaterally forces a history change, that will be apparent to everyone and they can choose to reject those changes…

        Ok, I think we’ve established that we disagree what a blockchain is. Doesn’t really matter I suppose, nice talking with you!
