This seems to be extremely different to Gerrit. Gerrit requires a centralised server which acts in place of a regular git server. It has its own database, distinct from git, and adds the notion of a "Change ID". Generally you do your review through a web interface. It's all quite clunky, but it does its job very well.

This is distributed but more importantly it looks like it's more entangled/in-tune with git. It says it uses git notes [1], which appeals to me; they're a feature that are basically useless on their own, but seem to be included exactly for the use of something like git-appraise.

Regarding your comment about a central repo, I'd guess the idea is you use git-appraise like you use git today; it's decentralised in the technical layers, but you assign "central" repo in the human workflow layer.
