Blockchain-Enabled Secure Transactions in V2G Networks

The increasing integration of Vehicle-to-Grid (V2G) systems in modern energy networks necessitates secure, transparent, and efficient mechanisms for energy trading. However, existing centralized approaches are susceptible to cyberattacks, lack transparency, and face scalability challenges. This paper proposes a blockchain-enabled decentralized platform to ensure secure and tamper-proof energy transactions between electric vehicles (EVs) and the grid. The system leverages smart con-tracts for automated settlements, cryptographic protocols for enhanced data privacy, and artificial intelligence (AI) models for real-time anomaly detection and fraud prevention. By integrating blockchain's transparency and immutability with AI's adaptability, the proposed solution addresses key challenges in trust, scalability, and cybersecurity. A prototype implementation demonstrates the platform's effectiveness, achieving improved transaction throughput, reduced latency, and enhanced resistance to malicious activities compared to traditional systems. Extensive simulations validate the scalability and resilience of the proposed framework under varying transaction loads and attack scenarios. This work lays the foundation for a transformative approach to energy trading, fostering increased trust, participation, and sustainability in V2G markets.
