Replication package: Verifiable Settlement Integrity for Peer-to-Peer Energy Trading in Community Microgrids under a Vertically Integrated Utility

Résumé fourni par la source

Code, input data, and measurement records reproducing every reported number of the paper: the CBCA peer-to-peer trading simulation on the IEEE 33-bus feeder, the commit-and-prove layer (Pedersen and Poseidon commitments, Groth16 anchor circuits over BN254), the integer-exact C0–C15 constraint checker with nine attack scenarios, and the on-chain gas measurements taken on a Hyperledger Besu private network. Each on-chain record carries the transaction hash it was read from.Version 3 (2026-09-07): adds the community self-supply sweep (_e1_selfsupply_20260904.json), the paired dense-vs-sparse proving benchmark (_prove_dense_vs_sparse_20260902.json) with its script, a provenance record for every reported number (_paper_number_provenance_20260902.json), and a corrected internalization-threshold record (_p3_internalization_with_outlay.json) that supersedes _p3_internalization.json: the earlier file computed the threshold without the forgone-charge outlay and therefore reported it below 1, opposite to the manuscript. The circuit attack suite also now tests concealment in the intended direction.
