Halseth is making an *actual* proposal for zk channel announcements in LN gossip! :
https://delvingbitcoin.org/t/zk-gossip-for-lightning-channel-announcements/1407/
This topic has fascinated me for the last couple years. LN has a kind of unique position to blaze the trail of creating pure cost based, fully private, anti Sybil/DOS of the type that every privacy network needs.
(Disclaimer: I don't believe PoW works, long term, for anything outside of bitcoin. Probably. )
As you can see here:

proving time without gpu acceleration is no good as of yet (15 mins on my kinda normal laptop). Let's see if optimization brings it down a ton.
Aut-ct proving times are 1-2 seconds. I think curve trees are a better solution for this, but it is extremely debatable.
