Write yourself a Git (2018)

Mercurial uses a DAG just like git. It has facilities for embedding a branch name in each commit, or for not doing that and having anonymous branches. It also has a feature similar to git's "branches"

Two articles that might help if you really want to dig into it:

Hmm, so the branch names are part of the commit's metadata. I'm not sure I agree with that, but I guess it's a valid choice.

The first article also states that unnamed branches are useful for small, temporary diversions, and notes that git has to name branches, but I think that's somewhat misrepresenting git since you can throw away names as soon as they are no longer useful. To me it seems kind of silly to have unnamed branches, given that names are free and much easier to remember than commit hashes.
