What is Nostr's topology? Imagine it like a bunch of websites (relays) serving different content. You connect to specific relays for the content you want, like an open market of data exchange. @NVK and @fiatjaf explain how nostr's topology results in its decentralization, in BR080. https://m.primal.net/LbAQ.mov
They are not quite web sites, they are web servers. Most relay are web servers without a website. Its a bit like using a car radio. Listening to some music, then walking home.
