-### ✈️ WebTransport

-**Status**: In progress
-
-**What?** WebTransport is a browser-API offering low-latency, bidirectional
-client-server messaging running on top of QUIC. The browser API allows the
-establishment of connections to servers that don't have a TLS certificate
-signed by a certificate authority if the hash of the certificate is known in
-advance.

-**Why?** This allows libp2p nodes running in the browser (using js-libp2p) to
-connect to the rest of the libp2p network.
