Off-Chain Secure Storage documentation

This project implements a secure off-chain data storage solution using OP-TEE (Open Portable Trusted Execution Environment) for IoT sensor data management.

The system main purpose is storing sensitive data off-chain while maintaining blockchain-level integrity and auditability through cryptographic hashing.
