7. 7 What is NOSTR anyway? What is NOSTR anyway? A decentralized network based on cryptographic keypairs and that is not peer-to-peer, it is super simple and scalable and therefore has a chance of working. Base layer protocol for a distributed social network
8. 8 How does it work? How does it work? • There are two components: clients and relays. Each user runs a client. Anyone can run a relay. • Every user is identified by a public key. Every post is signed. Every client validates these signatures. • Clients fetch data from relays of their choice and publish data to other relays of their choice. A relay doesn't talk to another relay, only directly to users. • For example, to "follow" someone a user just instructs their client to query the relays it knows for posts from that public key. • On startup, a client queries data from all relays it knows for all users it follows (for example, all updates from the last day), then displays that data to the user chronologically. • A "post" can contain any kind of structured data, but the most used ones are going to find their way into the standard so all clients and relays can handle them seamlessly. Kinda like a decentralized twitter

12. 12 What Client should I use? What Client should I use? Damus (iOS) Damus is currently available on TestFlight with and App store request in process. Closest to a Twitter replacement Has Bitcoin Lightning Tipping enabled
13. 13 What Client should I use? What Client should I use? Snort.Social (Mobile-Web) Similar to Damus with decent mobile- web UI. Use on Android with Kiwi browser and nos2x Chrome plugin. Lightning implementation for tipping.
14. 14 What Client should I use? What Client should I use? Astral.ninja (Desktop-Web) Twitter-like full desktop UI. Use w/ Alby Chrome plugin to store private keys in separate container and connect to an existing lightning wallet such as BlueWallet. Lightning QR codes enabled.

16. 16 Some things to be bullish about Some things to be bullish about Nostr.net A curated list of nostr projects and resources nostrnode-cli nostrnode receives encrypted rpc commands intended for Core Lightning, Join Market and Bitcoin Core. nostrnode decrypts the command, builds the http request for localhost and forwards it to the correct service (identified by port for now). nostrnode takes the response from said service, encrypts it, packages it into a nostr event and sends it to the relay which forwards it to the client.
