摘要
We implement privacy-preserving local electricity exchanges using an automated market maker on the Hyperledger Besu network under QBFT consensus. The proposed protocol operator collects individual electricity positions off-chain and publishes aggregate supply and demand on the blockchain, where smart contracts compute market prices every fifteen minutes. Individual positions remain off-chain; Poseidon2 commitments and UltraHonk zeroknowledge proofs, generated from Noir circuits, verify aggregation, payments, and daily balance updates. The architecture retains community coordination while making financial execution independently auditable. Signed receipts and member-triggered recourse prevent unverified or partial settlement. In a ten-household experiment using simulated US residential profiles, daily settlement uses approximately 19 million gas and produces eight-member proofs in 2.4 seconds. Over four simulated days, local trading covers 34.4% of demand and reduces grid-only costs by 30.5% under assumed tariffs. Numerically computed __-Nash Equilibrium electricity profiles capture 83-88% of the social planner surplus.
