+### ✈️ 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.
