Abstract: Volatile electricity prices enable arbitrage by charging storage when prices are low and discharging when prices are high. We propose a blockchain-backed 'energy accumulator' for communities and microgrids that aggregates heterogeneous storage assets, tokenizes their time-coupled capacity (kWh•slot), and executes charge/discharge schedules via smart contracts connected to price and telemetry oracles. Off-chain forecasting and optimization generate dispatch plans; on-chain contracts provide transparent settlement, constraint enforcement (SoC, cycle limits), and profit sharing. The concept targets low transaction latency (minutes) and negligible onchain overhead relative to arbitrage margin. We outline a simulation framework using historical price series, storage models with degradation costs, and compare three governance modes: centralized operator, permissioned blockchain (PBFT/PoA), and public L2 rollup. Key metrics include arbitrage profit, peak reduction, SoC violations, gas/fees, and CO2 impact. Results (to be developed) will quantify where blockchain brings net value beyond centralized coordination.
