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?

    Good summary, a few additions from my side:

    • Being public is not required. E.g. banks could form an internal block chain shared only with other banks.
    • Blockchains are a database. An immutable and usually distributed database.

      I would argue against blockchains being a database… its more of a ‘signed sequential log’ than a database.

        Well, Wikipedia describes it sufficiently vague: “a database is an organized collection of data”. But is a linked list on its own a database? I’d say the blockchain itself is the data structure but any software using it is most likely a database.
