چکیده :

This paper proposes a blockchain-enabled, intermediary-free architecture for peer-to-peer (P2P) energy trading that couples cooperative game theory with a lightweight Proof of Cooperative Energy (PoCE) consensus to achieve security, privacy, and fair settlement. Smart contracts handle pricing and clearing without third-party brokers, while access-controlled ledgers and pseudonymous identities protect metering data and transactions. PoCE elects the validator by coalition contribution -loss reduction and local balancing- rather than hashing power, and distributes dual incentives (mining and coalition rewards) using Shapley-based payoffs to align individual and system objectives. The market is cast as a cost-minimization cooperative game with network-loss penalties and transaction costs. Evaluation on the IEEE 33-bus feeder with 10 prosumers shows feeder-loss reduction, cost savings. Compared with no-coalition, Proof of Stake (PoS), and Proof of Energy Generation (PoEG), PoCE achieves higher local matching, ~1.8 s validation latency with ~450 TPS, and preserves privacy through minimal on-chain disclosure—demonstrating a practical route to scalable, fair, and physics-aligned P2P energy trading.
