I appreciate the suggestion and response. Understand it is v.0.1.0 but you should also understand that when you bring something like this out with next to no academic backing…

Objections
Eventual consistency and conflict resolution claims lack formal proofs or papers
From 2 comments
I'm not saying you claimed to have all three. Only paper I would have in mind is the CRDT paper from Letia, Preguiça, and Shapiro which I'm sure you're already familiar with. The…
karlgrz on HNThanks! :) Quick question though: I'm claiming an AP system, not that I have all three. What research are you referring to that suggests you can't have idempotent/deterministic…

Did you read https://github.com/amark/gun/wiki/How-to-Create-GUN ? It is only introductory though. The slides might be helpful. I've demonstrated GUN before handling conflict…

Questions
Is it strongly consistent or only eventually consistent
From 2 comments
Maybe I wasn't clear... GUN does have Eventual consistency, but not strong/global consistency. Aka GUN is AP and Eventually consistent. You manually at the application layer can…

Persistence options beyond S3 and local disk
From 1 comment
Persistence is just a plugin/module/hook. Currently it plugs into a very never-should-ever-be-deployed file on disk (for easy local testing only) and S3. We're going to be adding…

I didn't downvote you, so please don't think I'm the one trying to bury you. I'm calling it GUN because it is powerful and therefore a dangerous tool to wield. Because I'm going…
