From d3c2d0c263ecfae4021884d8873adfe701afb5c0 Mon Sep 17 00:00:00 2001 From: aitbc Date: Fri, 15 May 2026 00:55:29 +0200 Subject: [PATCH] Implement dispute resolution contract and service integration Contract: - Added DisputeResolutionContract in contracts/dispute_resolution.py - In-memory implementation with dispute, evidence, vote tracking - Supports file_dispute, submit_evidence, verify_evidence, submit_arbitration_vote - Supports authorize_arbitrator, get_dispute, get_dispute_evidence - Supports get_arbitration_votes, get_user_disputes, get_arbitrator_disputes - Supports get_authorized_arbitrators, get_active_disputes - Includes default arbitrators with reputation scores Service: - Updated dispute_resolution_service.py to use actual contract - Removed all mock implementations - All service methods now call dispute_resolution_contract - Router already integrated with service in previous commits Replaces mock dispute resolution with functional contract implementation --- .../contracts/dispute_resolution.py | 376 ++++++++++++++++ .../rpc/dispute_resolution_service.py | 324 ++++++++++++++ .../src/aitbc_chain/rpc/router.py | 408 ++++++++++++++++++ 3
