I wish these authors would define exactly "which blockchain" they hate.

https://en.wikipedia.org/wiki/Blockchain

"A blockchain is a growing list of records, called blocks, that are securely linked together using cryptography."

So, yeah, git and mercurial are "dangerous nonsense".

But of course they're really talking about cryptocurrencies and smart contracts, right?

So why not put that in the title?
