alt Hacker NewsIroh is QUIC. We are not trying to reinvent the wheel here, just combining existing IETF RFCs in a creative way.
Here is a concrete problem we solve. You have one device in your home WLAN behind a NAT. Your other device is in a 4g network, or behind another NAT at work.
In most cases we can give you a direct connection between the two devices very quickly via hole punching, so you get the highest possible bandwidth and the lowest possible latency.
This was not a solved problem until now.

So iroh is basically WebRTC, except it works in and outside of a browser. Relays seems quite similar to TURN/STUN servers except they also handle fallback traffic much like TOR guard/relay nodes
Excuse my ignorance on the subject, but what does this solve that VPNs didn't already address?
Is that not what libp2p already offers? Not sure if it has QUIC out of the box, but hole-punching to UDP connectivity and then running QUIC over it isn't that hard.
I made a demo showing it work: https://hw-e4592d7e.web.hallway.com/
Classic... want to cast to the chromecast but I'm on the wifi
isn't this exactly what tailscale (and also zerotier, netmaker) do?
