nostr Resources

TL;DR: nostr1 is a protocol that has the power to replace twitter, Telegram, and other things.

WTF is nostr?

You, probably

nostr is new and confusing but also really cool. It 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, therefore it works.

Get Started #

While there are many clients, the following three are currently quite popular: Damus for iOS, Amethyst for Android, and Iris for Web.

Learn More #

nostr’s design is very basic:

  • 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.

To use nostr, you need a key and a client.

  • Everybody runs a client. It can be a native client, a web client, etc.
  • To publish something, you write a post, sign it with your key and send it to multiple relays (servers hosted by someone else, or yourself).
  • To get updates from other people, you ask multiple relays if they know anything about these other people.
  • Anyone can run a relay. A relay is very simple and dumb. It does nothing besides accepting posts from some people and forwarding to others.
  • Relays don’t have to be trusted. Signatures are verified on the client side.

Keys #

Your keys are your identity. You can think of your public key (npub...) as your username and your private key (nsec...) as your password.

Two quick things:

  • Store your keys securely and do not share your private key

Keys exist in two formats, hex and the above mentioned npub/nsec. You can use a key converter tool3 to convert between the two formats.

Use Alby or nos2x to generate your keys, or generate them using a dedicated tool like rana or nostrogen. The aforementioned extensions will store your keys safely (or at least more safely).

You can also generate your keys by other means if you know what you’re doing.4 It’s still early days, so be prepared to get rekt.

Clients #

Periodically check which keeps a curated list of clients or have a look at the client comparison table.

Mobile clients:

There are more native clients in development, Nostros6 and Nozzle7 being two of them.

Web clients:

  • - Explore your tribe, network, and global trends
  • - Simple interface with automatic image-upload
  • noStrudel - Supports many NIPs inc communities, streams, blogs and more
  • - Search, filters, and micro-apps
  • - Mobile-friendly and twitter-like
  • - Clean interface & rich in features
  • - Focus on images and media, supports multiple layout styles

On Android you can use the Kiwi Browser to use the Alby or nos2x extension, which allows you to use any web client.

There’s also Nostr Console, noscl, and nostr-commander if you’re into CLI stuff.

Web clients for content creators:

  • ZapStream - Streaming on nostr allows for instant monetarisation of content.
  • Habla and yakihonne - Longform posts on nostr similar to Medium.
  • Stemstr - Share your music with the world and let others collaborate.
  • Wavelake - A music platform similar to Spotify.
  • - Focuses on moderated communities like reddit but also offers CDN media hosting and other nostr services.

Desktop clients:

Relays #

Relays are dumb servers that you can leave behind at any time (so they can’t turn evil). You need to connect your client to a relay for it to work. There are many relays & you can run your own.

Run your own:

Paid relays:

Paid relays effectively deal with spam by charging users a small usage fee in sats. You can set your global feed to paid relays only, which will get rid of almost all spam.

Tools #

nostr can do more than just social media.

  • Sendstr - shared clipboard between devices over nostr.
  • nosbin - pastebin over nostr.
  • Metadata Nostr - A profile and following list backup tool.
  • NostrSync - Another service to backup profile AND nostr events.

Games #

Games? WTF? Yes, games:

  • Jester - Chess over nostr by theborakompanioni

Tips & Tricks #

Some things work a bit differently and aren’t always obvious, such as:

Finding others #

Use this search query to find nostr keys of people you follow on twitter:

This uses the verification message, but the &pf=1 limits the twitter search to only people you follow.

Posting images #

Many popular clients support image uploads directly. (Keep in mind that all uploaded images to external hosts are public, so don’t upload confidential things willy-nilly.)

Most clients will display image URLs as images, so you can just upload any image to image sharing sites and post the URL like this:

This also works for videos.

Here are some free image hosts:

You can also use your Twitter display picture by following this guide.

Verifying yourself #

If you have a domain and want to have a “verified” checkmark, here is some useful info:

There are also centralized verification services that you can use, but be aware that all these are centralized and that they can rug-pull you at any moment:

Provider missing? Price changed?

Receiving Zaps #

Zaps are V4V lightning payments that are broadcast as nostr events, so that clients can display them on user profiles and specific notes.

To receive zaps you need a lightning wallet that supports NIP-57.

Popular custodial solutions are:

Self-custodial solutions:

To use Lightning Tip Bot in a more private way, you can:

  1. Use sms4sats to sign up to Telegram
  2. Create an wallet
  3. Type /nostr add <your_npub> to add your npub
  4. Type /advanced to see your anonymous lightning address…
  5. …and add it to your nostr profile. Done!

You can mention a note or a user by putting an “@” before an npub or note like this:

  • @npub1dergggklka99wwrs92yz8wdjs952h2ux2ha2ed598ngwu9w7a6fsh9xzpc
  • @note1m2ev3e2ma7a84rr8053qhsggeg6apmp00445v8k7tyeqvhu5u8aqpc30sp

When mentioning a note in another note, the note will be shown as a quote-note.9

Most clients support the nostr: URL scheme as defined in NIP-21, which means you can link to your nostr profile by putting “nostr:” in front of your npub. This will result in a link that opens in the user’s nostr client, like so: open my nostr profile.

You can use this for http redirects too, which can be used as a way to verify your nostr profile if you own a domain, like so:

There is even a redirect tool that you can use; h/t to David for putting it together.

Stats #

Ever since Jack joined (and funded some nostr devs) and Elon put it on his naughty list a flood of people came streaming in. Since everything is out in the open, you can see this nicely in the stats.

Sats #

Some clients will render Lightning invoices natively, showing the recipient, amount, and a pay button. One such client is Damus, which shows a nice little widget and a pay button.

Most clients support search, but there’s also:

You can also create a search bot at and then follow it to receive new posts matching a keyword or hashtag right into your feed.

Bots #


You can also create an RSS feed with posts matching some keywords at and use your favorite RSS reader app to follow different nostr conversations.

Podcasts #


Explorers #

Privacy #

There are multiple privacy issues when it comes to using nostr.

Your IP address is exposed to the relays you connect to, so consider using a VPN or similar. Some clients also support connecting via Tor. Tor nostr relays exist, but not all clients support Tor nostr relays.

Relays also know which public keys you are requesting, meaning your public key will be tied to your IP address.

Privacy & Image Uploads #

Some third party media hosters may be able to see, and share your IP address.

Privacy & Direct Messages #

Only the message content is encrypted on Nostr: the sender, recipient and timestamp are visible to everyone.

About #

This project evolved out of a gist that was quite hastily put together. Its purpose was to help people wrap their heads around nostr, and I guess this is the purpose still.

Some of the text above is copied from nostr-protocol/nostr and I just left some stuff out, so consider the descriptions and explanations an opinionated summary.

If you found a typo, please fix it. If you have suggestions, please create an issue. If you want to scream at me because you think this whole thing is stupid, please find me on nostr.

  1. nostr = Notes and Other Stuff Transmitted by Relays 

  2. You have to trust whoever is running the website, obviously, and some clients are vulnerable to XSS attacks. A lot of people got rekt already, and had to re-build their nostr identity because of it. 

  3. There’s also the but DO NOT use it for private key conversions. Don’t paste your private key into websites. Just don’t. 

  4. BIP-85 is an option, for example. 

  5. Apple Silicone only (M1 or M2 chip) 

  6. KoalaSat/nostros 

  7. dluvian/Nozzle 

  8. Fork with small modifications/fixes: Install a nostr relay 

  9. How’s that for a tongue twister?
