What is Nostr?

Nostr (Notes and Other Stuff Transmitted by Relays) is a simple, open protocol that enables truly decentralized social media. Understanding Nostr helps you understand why Nostria is different from traditional platforms.

The Simple Explanation

Imagine if email and social media had a baby—that's Nostr!

Just like email:

  • No central authority: No single company controls it
  • Portable identity: Your identity works across all clients
  • Choose your provider: Use any app or relay you want
  • Can't be shut down: Decentralized infrastructure

How Nostr Works

The Three Core Components

1. Your Keys (Identity)

  • Public key: Your username (shareable)
  • Private key: Your password (keep secret!)
  • Same keys work everywhere on Nostr

2. Relays (Servers)

  • Store and forward messages
  • Anyone can run a relay
  • Connect to multiple relays
  • Like email servers, but for social posts

3. Clients (Apps)

  • User interface to Nostr
  • Nostria is a Nostr client
  • Many clients available
  • All work with same keys

The Flow

When you post on Nostria:

  1. You write a message
  2. Nostria signs it with your private key
  3. Sent to relays you're connected to
  4. Relays store it and forward to others
  5. Others fetch it from relays they use
  6. They verify it's really from you

Key Principles

Decentralization

  • No single point of control
  • No company owns the network
  • Resistant to censorship
  • Can't be shut down

Simplicity

  • Minimalist protocol
  • Easy to implement
  • Flexible and extensible
  • Anyone can build on it

User Ownership

  • You own your identity
  • You control your data
  • You choose your experience
  • No platform lock-in

Interoperability

  • Works across all clients
  • Same identity everywhere
  • Share data between apps
  • Open ecosystem

Why Nostr Matters

Problems with Traditional Social Media

Corporate control: Companies own your account and data ❌ Censorship: Platforms can ban you anytime ❌ Vendor lock-in: Can't take your followers elsewhere ❌ Algorithm manipulation: Feed controlled by the platform ❌ Privacy invasion: Your data is mined and sold ❌ Single point of failure: Platform goes down, you're offline

How Nostr Solves These

User control: You own your identity and data ✅ Censorship resistance: No central authority to ban you ✅ Portability: Take your identity and followers anywhere ✅ Your algorithm: Choose how you see content ✅ Privacy first: Only share what you choose ✅ Resilient: If one relay fails, others work

Nostr vs Other Platforms

Nostr vs Twitter/X

  • Nostr: Decentralized, you own your account
  • Twitter: Centralized, company owns everything

Nostr vs Mastodon

  • Nostr: Simple protocol, any client works
  • Mastodon: Federation, servers can still ban you

Nostr vs Blockchain Social Media

  • Nostr: Simple, fast, no tokens required
  • Blockchain: Complex, slow, often needs tokens

What Makes Nostr Special

Simple Protocol

Not bloated with features—just the essentials:

  • Publish messages
  • Subscribe to users
  • Verify signatures
  • That's it!

No Token Required

  • No cryptocurrency needed to use Nostr
  • Optional Bitcoin integration for tips
  • No "pay to play" mechanics
  • Free to use

True Freedom

  • Create unlimited identities
  • Run your own infrastructure
  • Choose your own relays
  • No platform rules (relay rules only)

Innovation Friendly

  • Anyone can build clients
  • Easy to implement new features
  • Extensible through NIPs
  • Active development community

Technical Deep Dive

Message Format (Events)

{
  "id": "event-id",
  "pubkey": "author-public-key",
  "created_at": 1234567890,
  "kind": 1,
  "tags": [],
  "content": "Hello Nostr!",
  "sig": "signature"
}

Event Types (Kinds)

  • Kind 0: Profile metadata
  • Kind 1: Text notes (posts)
  • Kind 3: Contact list (follows)
  • Kind 4: Encrypted direct messages
  • Kind 7: Reactions (likes)
  • And many more defined by NIPs

Cryptography

  • Uses elliptic curve cryptography (secp256k1)
  • Same as Bitcoin
  • Public/private key pairs
  • Schnorr signatures

NIPs (Nostr Implementation Possibilities)

NIPs are like RFCs for Nostr—they define features:

  • NIP-01: Basic protocol
  • NIP-02: Contact lists
  • NIP-04: Encrypted DMs
  • NIP-05: Verification
  • NIP-09: Event deletion
  • Many more!

Limitations & Trade-offs

Current Challenges

  • Spam: Open network can have spam
  • Storage: Who pays for relay storage?
  • Discovery: Finding content can be harder
  • User experience: Still evolving
  • Relay reliability: Some relays go offline

Solutions in Progress

  • Proof-of-work for spam prevention
  • Paid relays for sustainability
  • Better recommendation algorithms
  • Improved clients (like Nostria!)
  • Redundant relay connections

The Future of Nostr

Short Term

  • Better mobile apps
  • More users and content
  • Improved performance
  • Enhanced features
