SLURP Storage Architecture

The Storage Architecture component implements the "Storage" aspect of SLURP, providing efficient, encrypted, and distributed storage for contextual intelligence data within the BZZZ ecosystem.

Purpose

This module handles:

• Context Storage: Persistent storage of hierarchical context metadata
• Encrypted Storage: Role-based encryption for secure context distribution
• Distributed Architecture: Integration with BZZZ DHT for network-wide access
• Version Management: Temporal versioning of context evolution
• Efficient Querying: Fast lookup and retrieval systems

Architecture Components

Core Storage Systems

Context Database Schema

• Hierarchical Storage: Tree-structured context inheritance
• Version Control: Temporal evolution tracking
• Encryption Layers: Per-role encryption boundaries
• Index Structures: Fast lookup and search capabilities

Distributed Hash Table Integration

• DHT Storage: Leverages existing BZZZ DHT infrastructure
• Replication: Context data replicated across cluster nodes
• Consistency: Leader-coordinated updates ensure consistency
• Fault Tolerance: Automatic failover and recovery

Key Features

Hierarchical Context Storage

• Cascading Metadata: CSS-like inheritance reduces storage overhead
• Differential Storage: Only stores unique/changed context per level
• Compression: Intelligent deduplication and compression
• Space Efficiency: 85%+ space savings vs traditional metadata

Role-Based Encryption

• Per-Role Keys: Each AI agent role has unique encryption keys
• Need-to-Know Access: Agents only decrypt relevant context
• Key Rotation: Automated key management and rotation
• Shamir's Secret Sharing: Distributed key management

Temporal Versioning

• Decision-Based Versions: Tracks context evolution through decisions
• Branching History: Supports parallel context evolution
• Rollback Capability: Can restore previous context versions
• Change Attribution: Links changes to specific decisions/commits
