# Security Model

## Core Security Design

### Multi-Layer Protection

Dozer Finance implements a comprehensive security model:

1. Bitcoin Network Security
2. Protocol-Level Protection
3. Smart Contract Security
4. Transaction Safety

### Bitcoin Security Integration

2. **MEV Protection**
   * Fair transaction ordering
   * Front-running prevention
   * Sandwich attack protection
   * Price manipulation resistance

### Network Security

* Distributed validation
* Node synchronization
* State consistency
* Data integrity

## Smart Contract Security

### Contract Design

* Pre-audited templates
* Security-first approach
* Robust testing
* Best practices implementation

### Protection Mechanisms

* Input validation
* State management
* Error handling

## Operational Security

### Infrastructure

1. **Node Operation**
   * Secure configuration
   * Regular updates
   * Performance monitoring
   * Attack detection
2. **Network Participation**
   * Distributed operation
