LiDIA: A Lightweight DPoS-IPFS Architecture for Scalable and Secure IoT Networks

Abstract

In the deployment of smart home IoT there is a critical security Loopholes that centralized management system are not able to solve. We present LiDIA, a lightweight Delegated Proof-of-Stake (DPoS) blockchain framework integrating Inter Planetary File System (IPFS) distributed storage and zeroknowledge authentication for residential IoT. we performed various simulation and result demonstrate end-to-end confirmation averaging 18 ms, throughput exceeding 1,200 Transactions Per Second (TPS), device-level energy reductions exceeding 99% over Proof-of-Work and AI-driven threat detection accuracy of 87.3% 92.5%, establishing a scalable and secure foundation for smart home environments.
