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?

They already are in most countries. E.g. in Poland land registry is maintained by court system and any changes are made only as a result of court order or a filing made by a notary public, who has a real incentive to check all the documents, because they are on the hook financially for any false filings.

    In other words, this is a solved problem without any blockchain nonsense.

    Updates lag 4-6 months after filing, so not 100% solved.

    also 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.

    Usually, lag like that is due to an ancient codebase, database, and process setup. If you were to solve that, you still wouldn't need blockchain. The software and process engineering does need careful consideration--almost all the stuff like this has had at least one major attempt to replace it over the decades, and it obviously failed--but again, nothing you would be able to solve just because blockchain.
