Data & Storage Layer

The Data & Storage Layer serves as the central repository and integrity engine for all agarwood supply chain data. It ensures secure storage, traceability, and immutable recordkeeping, bridging raw device inputs and the blockchain core.

1. Core Functions

1. Data Storage
   • On-Chain Data:
     • Batch IDs, timestamps, event hashes, and smart contract execution logs
     • Status flags for compliance, grading, and verification
   • Off-Chain Data:
     • Large datasets such as lab reports, high-resolution images, drone footage, and IoT sensor logs
     • Regulatory documents (CITES permits, export licenses, invoices)
2. Data Integrity & Validation
   • Off-chain files are hashed and anchored on-chain for tamper-proof verification.
   • Smart contracts validate event sequences before anchoring data.
   • Immutable cryptographic hashes provide auditable proof of authenticity.
3. Data Preprocessing & Standardization
   • Raw IoT, lab, and operator data are normalized into standardized formats.
   • Preprocessing supports AI analytics, growth predictions, and ESG reporting.
4. Secure Access & Encryption
   • AES-256 encryption for off-chain storage.
   • TLS-encrypted communication channels for data transfer.
   • Role-based access controls ensure only authorized participants can read or write data.

2. Data Flow Architecture

1. Ingestion:
   • Data captured by IoT sensors, drones, lab equipment, and mobile apps.
2. Preprocessing:
   • Edge nodes validate, filter, and format data.
3. Off-Chain Storage:
   • Large files stored securely with unique cryptographic hashes.
4. Blockchain Anchoring:
   • Event hashes, timestamps, and smart contract outputs stored on the permissioned blockchain.
5. Analytics & Reporting:
   • AI engines access off-chain and on-chain data for growth prediction, ESG metrics, and investor dashboards.

3. Storage Components & Technologies

Component	Purpose	Key Features
Blockchain Ledger	Immutable event logging	Batch hashes, smart contract logs, timestamps
Off-Chain Storage	Large file repository	Encrypted files, versioning, hash anchoring
Edge Data Store	Real-time preprocessing	IoT buffer, anomaly detection, compression
Data Gateway / API	Secure integration	Standardized data exchange with analytics and apps
Backup & Recovery	High availability	Multi-node replication, automated failover, disaster recovery

4. Key Features

• Hybrid Storage Model: Combines on-chain immutability with off-chain capacity.
• Traceability: Every piece of data is linked to a specific plantlet, tree, or batch.
• Scalability: Designed to handle high-volume IoT streams and large lab datasets.
• Audit-Ready: All hashes and timestamps provide verifiable chain-of-custody for regulators and buyers.
• Data Security: Encryption and access controls protect sensitive plantation, lab, and export data.

5. Benefits

• Guarantees integrity and authenticity of all supply chain data.
• Reduces risk of fraud, misreporting, or loss of critical documentation.
• Enables AI-driven insights and ESG reporting with reliable historical datasets.
• Supports investor confidence and global compliance with digital export documentation.

Summary:
The Data & Storage Layer is the backbone of the Crown Blockchain Solutions ecosystem. By combining on-chain immutability, off-chain capacity, preprocessing, and secure access, it ensures that all nursery, plantation, lab, harvest, processing, and export data is secure, traceable, and auditable, forming the foundation for smart contracts, AI analytics, and end-to-buyer verification.
