Registration with Spidernet based on Multi-Blockchain

The rapid growth of IoT devices raises challenges in identity management, security, traceability, and digital forensics. Traditional centralised registration methods face security and scalability issues. This paper proposes a Spidernetbased Multi-Blockchain architecture for registering IoT devices (DNAs) to enhance digital evidence acquisition. The multilayered model improves data distribution, redundancy, and fault tolerance. The Multi-Blockchain allows parallel processing and scalability for large IoT networks. A hybrid proof-of-stake and proof-of-activity consensus mechanism boosts security and energy efficiency. The Spidernet architecture outperforms traditional blockchains in transaction speed, latency, robustness, and digital evidence management, strengthening decentralised IoT ecosystems and digital forensics.
