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?

    No a blockchain is a chain of blocks. Its an append only datastructure that provides a cryptographically verifiable history. Proof-of-work is what allows for public concensus in crypto currencies like bitcoin, where as git uses signed blocks to identify different chains.

      Git doesn’t sign commits, at least not cryptographically. I can download the Linux git repo and add whatever commits I like to it. I can even create my own commits under Torvalds’ name and email if I’d like, or rewrite all his commits under my own name.

      It’s highly unlikely I can fool anyone it’s the real deal though. They will just download the kernel from the official repo instead.
