Blockchain-Enabled Secure Architecture for Smart Grid Energy Transactions and Decentralized Power Management

Abstract

The modernization of power systems through smart grids introduces bidirectional energy flows, distributed generation, and prosumer participation, creating new cybersecurity and transaction management challenges. This paper proposes a blockchain-enabled secure architecture for smart grid energy transactions and decentralized power management. The framework integrates distributed ledger technology, smart contracts, and consensus mechanisms to enable transparent, tamper-resistant, and automated peer-to-peer energy trading. A layered architecture is developed, incorporating IoT-based metering, cryptographic authentication, and decentralized control logic. Performance analysis demonstrates enhanced security, reduced transaction overhead, and improved trust among participants, supporting scalable and resilient decentralized energy ecosystems.
