CITA: A Consensus-Based Integrity and Transparency Algorithm for Decentralized Power Data Collection Systems

In modern power collection systems, ensuring data integrity and transparency is critical for maintaining grid reliability and trust among stakeholders. Traditional centralized systems are vulnerable to tampering, lack transparency, and are susceptible to cyberattacks. In this paper, we propose a Consensus-based Integrity and Transparency Algorithm (CITA) that integrates blockchain technology and smart contracts to enhance data security in decentralized power grids. CITA employs a dual-layer Proof of Stake (PoS) consensus mechanism to ensure the integrity of collected data and automate data verification through smart contracts. By utilizing off-chain storage, the system maintains scalability while reducing energy consumption. Experimental results show that CITA improves data integrity by 99.8%, reduces latency, and provides higher transparency compared to traditional and existing blockchain-based models. This makes CITA an ideal solution for real-time, secure, and scalable power data collection systems.
