Blockchains are public ledgers of information. It’s neat. It can be a practical way to keep a ledger. Apparently some banks use a blockchain to validate transactions now.
It’s the whole hype about how it would change the world, and the incredible amounts of grifting that poison Blockchain for the public. For far too many people, it’s just another get-rich-quick scheme.
Block chains do not need to be, and most real applications are not, public. Signing signed work has existed for decades, and almost every single use of it is in a private application.

you can have a public ledger of information without blockchain, we’ve done that for thousands of years in far more efficient ways.
Sure we can do without. We have done without many things for “thousands of years”. I seriously doubt that it was more efficient in all circumstances.
The claim of public ledgers having been more efficient for that long is so absurd to me that I’m doubting whether you are serious.
