I think you may be confusing "blockchain" with "bitcoin".

A blockchain is just blocks of data linked together using hash functions to guarantee the authenticity of previous blocks. There's no mining, and only a tiny amount of electricity used.

Isn't that a Merkle tree? "Blockchain" is not commonly used for what git does.

"Block chaining" is absolutely used to refer to that concept in cryptography, and pre-dates cryptocurrency.

[erosenbe0]

Correct. Block cipher, block list, block chain, block vector, array of blocks -- I'm sure you can find them all decades ago.

There’s a fair amount of confusion around that term, however: for example, Bitcoin proponents spent most of a decade saying that only proof-of-waste systems were true blockchains because they knew that anyone picking a different mechanism would have much better performance and cost numbers.

The anti-crypto bros don’t need that kind of nuance. Blockchains = bad, we don’t need to complicate their simple world with big words.

Why not just be charitable and not malign entire classes of people with certain opinions?
