*Building the decentralized infrastructure for legal intelligence*
</div>

## Overview

LN1 - a groundbreaking node that's revolutionizing how we process, validate, and manage legal data across the web. Our distributed architecture combines cutting-edge blockchain technology with advanced data processing capabilities to create a powerful legal intelligence network.

## Core Architecture

<p align="center">
<img src="..\images\AgenticLayer.png" alt="LN1 Agent Layer Architecture" width="600">
</p>

### Node Types
The LN1 system employs a sophisticated agent layer architecture that orchestrates multiple specialized components working in harmony. This innovative design enables seamless processing of legal documents from across the web, transforming raw data into valuable legal intelligence.

### Processing Components

The LN1 system implements several functional node types that handle different aspects of document processing. These are distinct from DataHive's specialized nodes (like Legalese Node, Consent Node, etc.) and represent the core processing components within each specialized node:
LN1's architecture is built around specialized processing nodes that work together to create a robust and efficient system. These components are distinct from DataHive's specialized business nodes (Legalese Node, Consent Node, etc.) and represent the core processing capabilities within each node:

```typescript
interface ProcessingNodeTypes {
INDEXER: 'Processes and catalogs legal documents',
VALIDATOR: 'Validates document integrity and content',
CURATOR: 'Manages document lifecycle and quality',
STORAGE: 'Handles distributed document storage'
INDEXER: 'Intelligent web crawling and document processing',
VALIDATOR: 'Advanced content validation and verification',
CURATOR: 'Smart document lifecycle management',
STORAGE: 'Distributed resilient storage system'
}
```

## System Layers
At its core, LN1 specializes in processing web-based legal documents:

### Data Layer
- **Intelligent Web Crawling**
- Privacy Policies
- Terms of Service
- Cookie Policies
- User Agreements
- Legal Notices

- **Document Storage**
- Distributed file system
- IPFS integration
- Redundancy management
```typescript
interface WebDocumentStorage {
distributed_storage: {
raw_html: IPFS; // Preserving original content
parsed_content: IPFS; // Structured legal data
};
metadata_store: {
source_url: string; // Document origin
last_updated: timestamp;
document_type: 'privacy_policy' | 'terms' | 'cookie_policy';
crawl_metadata: CrawlInfo;
};
state_store: Ethereum; // Immutable validation state
local_cache: Redis; // High-performance access
}
```

- **State Management**
- Blockchain state
- Document metadata
- Validation records
### Processing Layer: The Intelligence

### Network Layer
## Data Flow: The Journey

- **Node Communication**
- P2P protocol
- Message queuing
- State synchronization

### API Layer

```typescript
interface APIEndpoints {
'/documents': 'Document management endpoints',
'/validation': 'Validation service endpoints',
'/nodes': 'Node management endpoints',
'/metrics': 'System metrics and monitoring'
}
```

## Scalability Design

### Horizontal Scaling

- Dynamic node allocation
- Load balancing
- Sharding strategy

### Vertical Scaling

- Resource optimization
- Performance tuning
- Capacity planning

## Monitoring System

### Performance Metrics

- Transaction throughput
- Node health
- Network latency
- Storage utilization

### Alert System

```python
class MonitoringSystem:
def monitor_metrics(self):
return {
'node_health': self.check_node_health(),
'network_status': self.check_network_status(),
'storage_metrics': self.check_storage_metrics()
}
```
