Enables cross-vendor interoperability. -- Graph-of-Contracts registry: versioned schemas for adapters and data models; replay protection and auditability. -- Attestation enhancements: DID-based identities and hardware-backed attestation binding to contract permissions. -- Privacy-by-design primitives: secure aggregation and pluggable zero-knowledge proof stubs for verifiable compliance. -- Post-quantum readiness: crypto-hygiene considerations and key rotation strategies. -- Tamper-evident governance ledger: anchoring options to public ledgers for cross-organization auditability. -- Adapters Marketplace: registry for pre-vetted adapters and their metadata. -- Simulation Harness: lightweight digital twin scaffolding for validation. +- Core concepts +- EnergiBridge: maps GridGuard primitives to a vendor-agnostic intermediate representation (IR) +- Security contracts registry, attested adapters, verifiable optimization (proof stubs), tamper-evident governance ledger +- Starter adapters: DER/inverter and water pump (attestation scaffolding) -Project Structure (Python): -- src/gridguard_secure_attested_cross_domain_e/ - - contracts.py - - optimization.py - - attestation.py - - transport.py - - governance.py - - marketplace.py - - simulation.py - - __init__.py +This repository provides a minimal, production-ready skeleton designed to be extended in subsequent sprint phases.
