My goal is to add storage trie and state trie gossiping for Ethereum via VulcanizeDB. We are a couple of sprints away from that now. It seems like a “simple” interim step would be writing clients that can “fill in the blanks” of their fast history by pulling state from quorums archive nodes. I’ve read the geth source, it seems like we should be able to get quorum on a state and inject it. I’m basically suggesting out of protocol snapshotting, because I think that will have less political friction than trying to get it in-protocol (, also Casper the Friendly Finality Gadget will provide that).
Right now this just does smart contract watching. We need to add more usage documentation.
Here you can some my ranting about the fast/full issue (Sorry, Twitter threading isn’t the best):
