Npubs Tor Routing!?!

🤯

NTR -> NosTR

quoting nevent1q…a02g

Yesterday we were playing around with ideas at Sovereign Engineering (npub1s0v…rmq5) , we needed something to preserve anonymity for blossom users that communicate with DVMs.

📢 Introducing Onion-routing for event publishing

This introduces insane privacy guarantees, someone can publish an event and not even the relay they are publishing from can now it's them, nor their IP address.

Technically this works very similar to Lightning, the sender constructs a route of pubkeys and can bounce around the message through pubkeys willing to route for them.

The sender can include small ecash tokens inside each onion layer to pay for the routing.

No hop in the route until the last one knows what they are routing, who its coming from and the sender very explicitly defines through which relays it should hop.

(for the sake of debugging, I built a traceroute-like view, so the sender can see the event being bounced around the different relays; in real conditions a sender wouldn't use that to preserve privacy)

Think of this like tor, just faster.
