# LN1 Architecture

## System Overview

The LN1 platform implements a distributed architecture for legal document processing and validation, combining blockchain technology with specialized legal data management systems.

## Core Components

### Node Types

```typescript
interface NodeTypes {
INDEXER: 'Processes and catalogs legal documents',
VALIDATOR: 'Validates document integrity and content',
CURATOR: 'Manages document lifecycle and quality',
STORAGE: 'Handles distributed document storage'
}
```

### Component Interaction

## System Layers

### Data Layer

- **Document Storage**
- Distributed file system
- IPFS integration
- Redundancy management

- **State Management**
- Blockchain state
- Document metadata
- Validation records

### Processing Layer

```python
class ProcessingPipeline:
def __init__(self):
self.indexer = DocumentIndexer()
self.validator = ContentValidator()
self.curator = DataCurator()

async def process_document(self, document):
indexed = await self.indexer.process(document)
validated = await self.validator.validate(indexed)
return await self.curator.curate(validated)
```

### Network Layer

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

- **Consensus Management**
- Validation consensus
- State agreement
- Conflict resolution

## Infrastructure Components

### Node Clustering

</p>

### Storage Architecture

```typescript
interface StorageLayer {
distributed_storage: IPFS;
local_cache: Redis;
state_store: Ethereum;
metadata_store: PostgreSQL;
}
```

## Security Architecture

### Access Control

```solidity
contract AccessControl {
mapping(address => Role) public roles;
mapping(bytes32 => mapping(Role => bool)) public permissions;
function hasPermission(address user, bytes32 resource)
public
view
returns (bool)
{
return permissions[resource][roles[user]];
}
}
```

### Encryption Layer

- End-to-end encryption
- At-rest encryption
- Transport security

## Integration Points

### External Systems

- **Blockchain Networks**
- Ethereum mainnet
- OP Sepolia
- Cross-chain bridges

- **Storage Systems**
- IPFS
- Arweave
- Filecoin

### 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

## Data Flow

A[Document Input] --> B[Indexing]
B --> C[Validation]
C --> D[Curation]
D --> E[Storage]
E --> F[Distribution]
```

## 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()
}
```

## Deployment Architecture

### Container Structure

```yaml
version: '3.8'
services:
indexer:
image: ln1/indexer
depends_on:
- storage
- validator

validator:
image: ln1/validator
depends_on:
- consensus

curator:
image: ln1/curator
depends_on:
- indexer
```
### Network Configuration
- Load balancing
- Service discovery
- Failover handling
## Future Expansion
### Planned Components
- Advanced analytics engine
- Machine learning integration
- Cross-chain interoperability
- Enhanced security features
### Upgrade Path
- Backward compatibility
- Migration strategies
- Version management
