Nostr 101: A Beginner Guide to the Decentralized Social Network
How to join Nostr, how to create your account on Nostr, and what Nostr apps to use for beginners
What is Nostr?
Nostr (Notes and Other Stuff Transmitted by Relays) is a decentralized, censorship-resistant social protocol designed to give users control over their online identities and interactions. Unlike traditional social media platforms that rely on centralized servers and moderation, Nostr allows users to communicate directly through a network of independent relays. This makes it permissionless—meaning anyone can use it without needing approval from a corporation or government.
Key Features of Nostr:
- Decentralized: No single company controls Nostr; it operates on a distributed network of relays.
- Censorship-Resistant: Users cannot be banned from the network; they can always find a relay that will host their content.
- Permissionless: No accounts, phone numbers, or email verification required—just a cryptographic key pair.
Nostr Fixes the Problems of Big Tech
The internet today is controlled by a handful of companies. They decide who gets a platform, what content is allowed, and how your data is used. Nostr is built to fix that.
You don't own your account. On platforms like Twitter, Instagram, or TikTok, your account belongs to the company. They can suspend you, change the rules, or shut down entirely — and everything you've built disappears with them. On Nostr, your identity is yours. No company can take it away, because no company controls it.
You can be silenced at any time. Governments pressure platforms to remove content. Companies deplatform users based on shifting policies. Entire communities get wiped overnight. On Nostr, there's no central authority that can censor you. Your posts are distributed across independent servers, so no single entity can silence your voice.
Your data is the product. Big tech makes money by tracking everything you do and selling your attention to advertisers. Nostr doesn't have a company behind it — there's no one collecting your data, no ads, and no surveillance business model.
You're locked into one platform. Your Instagram followers can't see your tweets. Your Spotify playlists don't carry over to YouTube. Every app is a walled garden. On Nostr, one login works across every app — your followers, your posts, and your identity travel with you.
Nostr doesn't fix these problems by promising to do better — plenty of companies have made that promise. It fixes them by being a protocol where it's technically impossible for anyone to take power away from users.
How Nostr Differs from the Fediverse and Bluesky
Nostr is the only fully decentralized social network, but it shares similarities with the Fediverse and Bluesky. For a deeper dive, read our full Comparing Protocols guide.
Mostr Bridge: Connecting Nostr to the Fediverse
The Mostr Bridge is a powerful tool that connects the Nostr network with the Fediverse (e.g., Mastodon, Pleroma). This allows users to follow and interact with accounts across both ecosystems without needing to switch platforms. Explore the bridge here.
Nostr Apps
Nostr isn't just a Twitter alternative — it's an entire ecosystem of apps spanning every type of content you can imagine. And because your identity lives in your keys (not in any app's database), one account works everywhere. No more creating separate logins for your social feed, your music player, your blog, and your calendar. On Nostr, a single key pair is your universal login.
Here are just some of the types of content you can create, discover, and interact with across the Nostr ecosystem — all with the same account:

Nostr Relays
Relays are the servers that store and deliver your posts. Think of them like different mail carriers — your messages get sent through them to reach other people.
You don't need to think about relays to use Nostr; the defaults work great. But if you're curious, you can add or remove relays in Settings > Network.
Using multiple relays means your content is backed up in more places, making it harder for anyone to silence you. To dive deeper, read Understanding Nostr Relays.
How to Create an Account on Nostr
Getting started on Nostr takes less than a minute. Unlike traditional social media, there's no email address or phone number required — your identity is based on a pair of cryptographic keys. But don't worry, an app like Ditto handles all of that for you. Here's what it looks like:
When you sign up, the app generates two keys for you:
- Your public key (npub): This is your identity on Nostr — like a username. It's how people find and follow you, and you can share it freely.
- Your secret key (nsec): This is your password. It proves you are who you say you are. Keep it safe — there's no "forgot password" on Nostr, because no company controls your account.
That's what makes Nostr different: you own your identity. No company can lock you out, delete your account, or change the rules on you. Your keys are yours forever.
