Smart Contract-Based Decentralized Energy Trading Platform with AI-Enhanced Decision Support

The rapid digitalization of the energy sector and the growth of distributed energy resources have exposed the limitations of traditional centralized energy management and trading models. This shift has created a need for more flexible, transparent, and user-focused solutions. Blockchain technology addresses these needs by enabling secure, traceable, and direct transactions through a decentralized and immutable record system. Peer-to-peer energy trading platforms on the public Ethereum network, for example, allow producers and consumers to exchange energy securely without intermediaries. This study presents a blockchain-based system architecture for peer-to-peer energy distribution and trading, known as the Decentralized Energy Management System (DEMS). The system automates energy exchanges and payments using smart contracts, which enable secure, auditable, and traceable transactions through the use of energy tokens. An artificial intelligence-powered decision support module has also been integrated to optimize users' energy purchasing preferences. The study demonstrates the practical impact of combining blockchain and artificial intelligence technologies in P2P energy systems.
