There was this one guy, whom was a cryptocurrency fanatic but not a developer, who tried to convince me to get involved in a "blockchain code database for developers". I told him that Git uses a blockchain, and he simply couldn't accept that a blockchain has been used for years on something that isn't cool or possible to monetize.

It's pretty funny how people still think that a blockchain is this magical thing, yet I'm pretty sure anyone on HN is capable of writing a blockchain in an an hour or two. Maybe even less than that.
