Nostr (Notes and Other Stuff Transmitted by Relays) is the simplest open protocol that is able to create a censorship-resistant global "social" network once and for all.

It doesn't rely on any trusted central server, hence it is resilient; it is based on cryptographic keys and signatures, so it is tamperproof; it does not rely on P2P techniques, and therefore it works. Oh and obviously it does not use a blockchain at all.

This talk will give an overview of the features, the philosophy, the history of the protocol, and a live coding session to demonstrate how it works.
