it's quite technical, i'm working on a tiny part of the cryptography for this project, but this is a technology that will enable fully decentralised git hosting, with the metadata broadcast over nostr and available to any nostr relay running HORNET storage, watches the blockchain and can automatically detect updates for the files knowing what to ask for by the signed merkle root from peers, get the tree of parts and inventory each part one by one.
as well as enabling decentralised, distributed git hosting, it will also be applicable to nostr profiles as well, where you will be able to periodically snapshot updates to your profile and then all subscribers can quickly learn about a new batch of updates and get every single one of them.
this is the most exciting thing in my opinion, because it means that user data can be easily gathered for followers, and stuff like being able to enable paid relays to fully sync their users' subscriptions proactively.
