SmartAxiom IoT Management & Security Solution is a decentralized security platform that combines blockchain technology with edge computing to protect IoT networks. The solution addresses scalability challenges in traditional client-server IoT security architectures by moving authentication responsibility from central servers to the edge of the network. The platform deploys gateway devices that sit between IoT devices at the network edge and cloud servers at the center. It implements a peer-to-peer security model where authentication is handled by local edge nodes rather than a central authority. The system maintains three separate blockchain ledgers: one for IoT devices, one for gateways, and one for the cloud. The solution uses hardware-based cryptography to authenticate and identify participating nodes. Transactions are verified through majority consensus of local nodes, with all digital transactions recorded in a distributed ledger visible to all network participants. The ledger is designed to be tamper-proof, with the ability to add new entries but not delete or update previous records. When a device is compromised, other nodes in the network can recognize the tampering and isolate the affected device to prevent damage from spreading across the network. The platform processes data on gateway devices rather than relying solely on central servers, which reduces cloud costs and provides redundancy through distributed processing.
