Ask HN: What are some use cases of block chain? 2021

it's been 10+ years since blockchain was launched... yet to best of my knowledge only 'product' made out of blockchain is that facilitates speculation.

I've seen pro blockchain cultists argue all day, but the arguments were the same 10 years ago...so no mental gymnastics..

what are some examples of some successful current uses of blockchain?

Successful = The firm abc uses blockchain to do xyz.

Not Successful = startup built another facebook "BUT ON BLOCKCHAIN"
