It’s some MASQUE connect-ip based protocol. Message is encrypted to the blind relay, send to obscura (who can see only destination blind relay ip, not content) who forwards to relay where it is decapsulated and forwarded so the blind relay can’t see origin ip. All encapsulated in HTTP.

RFC 9484: Proxying IP in HTTP

This document describes how to proxy IP packets in HTTP. This protocol is similar to UDP proxying in HTTP but allows transmitting arbitrary IP pack...

Thoughts on Apple’s private relay? Please excuse my ignorance 🤘🏼💜

From their discord:

This is conceptually exactly what Apple Private Relay does. But Apple only does it for select Apps at TCP and UDP layer. This is IP layer. Apple Relay has some benefits. One example is b/c Apple will not allow IP location spoofing they get blocked a lot less. I like Apple Private Relay but am definitely looking forward to a generalized solution like this.

They are on Nostr: @Obscura VPN

Hmm... Where is the egress hop coming from? Isn't it also under their control?

There is a similar private VPN type project called SPN (Safing privacy network) which uses onion routing (3+ relays) with high bandwith and different IPs per app. They also support btc & xmr payments (no lightning though). Pretty powerful tool, you should check it out!
