I wish there were more info on how the Blind Relays work, but this is interesting; looking forward to reading more about it when it’s available
https://obscuravpn.io
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. https://datatracker.ietf.org/doc/draft-ietf-masque-connect-ip/
