The terms "chain", "blocks", "chain of blocks", "proof-of-work chain", "timestamp server" and "timechain" are all mentioned in the whitepaper and code. As far as I know, the term "blockchain" was never explicitly mentioned. I'm not even sure why or when people started calling it that. So, I don't really mind if shitcoiners have that term for themselfs.

Personally, I don't feel the need to come up with new terms or enforce them on shitcoiners.

They can have "crypto", and I'll stick with "Bitcoin". They can have "blockchain," and I'll go with "timechain", "timestamp server" which are the correct terms mentioned by satoshi.

There's no need to change anything imo.
