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?

    You can only guarantee the records have not been tampered with if you maintain a full copy of the records to compare. Even if you do have that full copy you will have a problem proving your copy is the correct one. A full crypto-verified ledger solves that.

    If you empower e.g. every change filer (court, notary public) to run a node fudging records becomes effectively impossible.
