😂 Actually you don’t need websockets over nostr because with http-over-nostr the client side can behave as a server and wait for requests initiated by others.
When you think about it, WebSockets themselves are kind of a hack. In the old days every computer had a public IP address and could open a port to wait for information from others. Today most computers are behind NAT and firewalls so to wait for information from some server you need to actively initiate a communication channel and keep it alive.
