... and, very notably, the hash of the parent commit. That is also part of the commit, which means that changing a parent commit would also imply changing the hashes of all later commits. This is sort of the whole point of git/version control.

This might be a stupid question, but does anyone call git history a blockchain, then? A centralized blockchain, without proof of work or proof of anything really of course, but still, it sounds like the basic blockchain idea is there
