+# LN1 Storage System
+
+## Overview
+
+The LN1 Storage System implements a distributed, fault-tolerant storage architecture for legal documents across the network. This system leverages the 0G network infrastructure while providing advanced caching, replication, and data integrity mechanisms.
+
+## Architecture
+
+### Core Components
+
+```python
+class StorageManager:
+    def __init__(self):
+        self.document_store = DocumentStore()
+        self.metadata_store = MetadataStore()
+        self.cache_manager = CacheManager()
+        self.replication_manager = ReplicationManager()
+```
+
+### Storage Layers
+
+1. **Primary Storage**
+   - 0G network integration
+   - Distributed hash table
+   - Content-addressable storage
+
+2. **Cache Layer**
+   - In-memory cache
+   - Local disk cache
+   - Network cache
+
+## Data Organization
+
+### Document Structure
+
+```typescript
+interface StoredDocument {
+    id: string;
+    content: {
+        raw: Buffer;
+        encrypted: Buffer;
+    };
+    metadata: {
+        size: number;
+        hash: string;
+        timestamp: string;
+        version: string;
+    };
+    storage: {
+        locations: string[];
+        replicas: number;
+        status: string;
+    }
+}
+```
+
+### Partitioning Strategy
+
+```python
+class PartitionManager:
+    def determine_partition(self, document):
+        return {
+            'jurisdiction': document.metadata.jurisdiction,
+            'year': document.metadata.date.year,
+            'category': document.metadata.category,
+            'shard': self.calculate_shard(document)
+        }
+```
+
+## Storage Operations
+
+### Document Storage
+
+```python
+class DocumentStore:
+    async def store_document(self, document):
+        # Prepare document
+        prepared = await self.prepare_document(document)
+
+        # Store in primary storage
+        storage_id = await self.primary_store.store(prepared)
+
+        # Update cache
+        await self.cache_manager.update(storage_id, prepared)
+
+        # Initiate replication
+        await self.replication_manager.replicate(storage_id, prepared)
+
+        return storage_id
+```
+
+### Retrieval Operations
+
+```python
+class DocumentRetriever:
+    async def retrieve_document(self, doc_id):
+        # Check cache first
+        if cached := await self.cache_manager.get(doc_id):
+            return cached
+
+        # Retrieve from primary storage
+        document = await self.primary_store.get(doc_id)
+
+        # Update cache
+        await self.cache_manager.set(doc_id, document)
+
+        return document
+```
+
+## Data Replication
+
+### Replication Strategy
+
+```python
+class ReplicationManager:
+    def __init__(self):
+        self.replication_factor = 3
+        self.node_selector = NodeSelector()
+
+    async def replicate_document(self, document):
+        nodes = await self.node_selector.select_nodes(
+            count=self.replication_factor,
+            document=document
+        )
+        return await self.distribute_to_nodes(document, nodes)
+```
+
+### Consistency Management
+
+```python
+class ConsistencyManager:
+    async def ensure_consistency(self, document_id):
+        versions = await self.collect_versions(document_id)
+        if conflicts := self.detect_conflicts(versions):
+            return await self.resolve_conflicts(conflicts)
+        return True
+```
+
+## Performance Optimization
+
+### Caching Strategy
+
+```python
+class CacheManager:
+    def __init__(self):
+        self.memory_cache = LRUCache(1000)
+        self.disk_cache = PersistentCache()
+        self.network_cache = DistributedCache()
+
+    async def get_document(self, doc_id):
+        # Multi-level cache implementation
+        return (
+            self.memory_cache.get(doc_id) or
+            await self.disk_cache.get(doc_id) or
+            await self.network_cache.get(doc_id)
+        )
+```
+
+### Resource Management
+
+- Dynamic cache sizing
+- Intelligent prefetching
+- Load-based replication
+- Adaptive compression
+
+## Security Implementation
+
+### Encryption
+
+```python
+class StorageEncryption:
+    def __init__(self):
+        self.key_manager = KeyManager()
+        self.cipher = AESCipher()
+
+    async def encrypt_document(self, document):
+        key = await self.key_manager.get_key()
+        return await self.cipher.encrypt(document, key)
+```
+
+### Access Control
+
+```python
+class AccessController:
+    async def verify_access(self, user, document):
+        permissions = await self.get_permissions(user)
+        return self.check_permission(permissions, document)
+```
+
+## Monitoring System
+
+### Health Checks
+
+```python
+class StorageMonitor:
+    async def check_health(self):
+        return {
+            'storage_usage': await self.check_storage_usage(),
+            'replication_status': await self.check_replicas(),
+            'cache_health': await self.check_cache(),
+            'performance_metrics': await self.get_metrics()
+        }
+```
+
+### Performance Metrics
+
+- Storage utilization
+- Access latency
+- Cache hit rates
+- Replication status
+
+## Error Handling
+
+### Recovery Procedures
+
+```python
+class ErrorHandler:
+    async def handle_storage_error(self, error):
+        await self.log_error(error)
+        recovery_action = self.determine_recovery_action(error)
+        return await self.execute_recovery(recovery_action)
+```
+
+### Backup System
+
+- Regular snapshots
+- Incremental backups
+- Point-in-time recovery
+- Disaster recovery
+
+## Integration Points
+
+### External Systems
+
+- 0G network interface
+- Blockchain storage
+- External APIs
+- Monitoring systems
+
+### Internal Components
+
+```python
+class StorageIntegration:
+    def __init__(self):
+        self.indexer = DocumentIndexer()
+        self.validator = ContentValidator()
+        self.curator = DataCurator()
+```
+
+## Best Practices
+
+### Implementation Guidelines
+
+1. **Data Organization**
+   - Use consistent naming conventions
+   - Implement proper versioning
+   - Maintain clear metadata
+   - Regular cleanup procedures
+
+2. **Performance Optimization**
+   - Optimize cache settings
+   - Monitor resource usage
