What the bounty proposes is a really complex project, which justifies the now 10 BTC reward.
The primary problem is storage of the Git repos. There are a few options, two of which are promising: GitTorrent and sending Git data over Nostr (but not storing anythign on Nostr).
The secondary problem is determining authenticity. I will have to do some more thinking about this, but I suspect that something like what Linux distributions do might be relevant.
Once someone manages to build this, it'll be the greatest project on Nostr, I've seen public repos I followed being taken down and private instances throwing 404s as costs and interest faded.
Having an open source project survive it's author without having forks over forks is way too cool for me.
Imagine a future where Nostr is being built on Nostr 🚀
