I saw this talk at DEFCON. It seems to combine ideas from IPFS, BitTorrent magnet links, Tor, and things like scuttlebutt. There was a very strong focus on privacy including for metadata.
The biggest weaknesses I saw were around DOS attack resistance, which I did not see addressed. There were good approaches for privacy and security but what if someone with resources (botnet or money) wants to just burn the network down?
Completely pure P2P systems are hard to protect against Sybil attacks whose goal is simply to degrade service. Just launch a ton of bots, have them act normal for a while, then have them start being tar pits or misbehaving in ways that are carefully designed to maximize errors and latency. Then have them randomly pretend to be normal for a while, toggling good/evil to blend in as much as possible.
Combined with strong privacy how do you identify and remove these? The alternative is to design a protocol so bulletproof that there is no viable DOS attack, or use tokenization to impose a high cost on such attacks. Of course the latter leads down the road to all the toxic craziness of the cryptocurrency ecosystem. Add a token and now you have a vector for pump and dump schemes even if you didn’t intend it as that.
I can think of many reasons someone might launch such an attack from troll wars all the way to nation states trying to kill comm vectors for espionage or uprisings.
All protocols really have to be designed as if your client is the defense department and they will be used in a war zone… because the Internet is a war zone.
