For those that have been seeing me ramble about this every chance I get. We've submitted the initial PR for our #IPLD #ProllyTrees spec.
This is a great building block for building #p2p databases which use sparsely replicated indexes to quickly load just the data that's needed.
Once we get some indexing going on top of these things, waiting for stuff to sync will be something you barely need to think about in P2P social apps! 🎉
