# Introduction to Sonr

<Note title="Scope">
  This document introduces Sonr's blockchain architecture, core components, and
  integration patterns. It covers identity management, authentication, data
  sovereignty, and cross-chain operations. This document does not cover
  implementation details or code examples—see the Quick Start Guide for hands-on
  tutorials.
</Note>

<Note title="Audience">
  **Developers** building Web3 applications who want simple integration
  patterns. **Validators** interested in securing a next-generation blockchain
  network. **Users** seeking sovereign digital identity solutions.
  Prerequisites: Basic understanding of web development (HTML/JavaScript) for
  developers; blockchain consensus for validators.
</Note>

## Summary

Sonr is a Cosmos SDK blockchain that simplifies Web3 through **Decentralized Identity (DIDs)**, **passwordless authentication (WebAuthn)**, and **user-controlled agents (Vaults)**. Developers integrate crypto features using standard web technologies. Validators secure a network bridging Web2 and Web3. Users gain digital sovereignty without complexity.

## What is Sonr?

Sonr transforms blockchain interaction through four innovations:

1. **W3C-compliant DIDs** replace wallet addresses
2. **WebAuthn** eliminates seed phrases
3. **Personal Vaults** automate blockchain operations
4. **UCAN permissions** prevent unlimited approvals

These components create a system where users onboard in 30 seconds using biometrics, developers add crypto features with HTML forms, and validators earn rewards securing digital sovereignty.

## Why Sonr Matters

### Current Problems

Traditional Web3 forces users to:

- Manage 24-word seed phrases
- Install browser extensions
- Understand gas fees
- Navigate multiple wallets

One mistake loses everything.

### Sonr's Solution

Sonr provides:

- **30-second onboarding** with Face ID or fingerprint
- **No seed phrases** through WebAuthn security
- **No gas fees** for account creation
- **Universal compatibility** across all devices
- **Automatic recovery** via social and biometric methods

## For Developers

### Integration Benefits

Sonr enables crypto features without blockchain knowledge:

- **Use existing skills**: HTML, CSS, JavaScript
- **Zero dependencies**: No SDKs or wallet libraries
- **Progressive enhancement**: Start simple, add features
- **Enterprise ready**: Integrates with existing auth systems

### Simple Payment Example

Transform any HTML form into a crypto payment interface:

```html
<form hx-post="/api/sonr/payment" hx-target="#result">
  <input type="email" name="recipient" placeholder="alice@sonr.id" />
  <input type="number" name="amount" placeholder="25.00" />
  <select name="currency">
    <option value="USDC">USDC</option>
    <option value="ATOM">ATOM</option>
  </select>
  <button type="submit">Send Payment</button>
</form>
```

Users approve with biometrics. Vaults handle transactions. No wallet connections required.

## For Validators

### Network Components

Validators secure four critical systems:

<CardGroup>
  <Card title="Blockchain Core" href="/blockchain/">
    Cosmos SDK with IBC for cross-chain operations
  </Card>
  <Card title="Token Economics" href="/blockchain/token/">
    Tokenomics, staking, and governance
  </Card>
  <Card title="Highway Proxy" href="/highway/">
    HTTP bridge supporting WebAuthn authentication
  </Card>
  <Card title="Validator Setup" href="/quickstart/validators">
    Validator node setup and operations
  </Card>
</CardGroup>

### Validator Operations

Validators perform five key functions:

1. **Validate identities**: Process DID operations and WebAuthn credentials
2. **Execute Vaults**: Run capability delegations and revocations
3. **Bridge chains**: Process IBC and InterchainAccount transactions
4. **Verify services**: Validate DNS ownership and registrations
5. **Coordinate MPC**: Participate in multi-party key management

### Economic Incentives

- **Block rewards**: Earn from transaction fees and inflation
- **Service fees**: Share revenue from registrations
- **MEV protection**: Built-in maximal extractable value prevention
- **Sustainable model**: Long-term network health design
