Implement all 6 phases of missing functionality
Phase 1: Agent SDK Marketplace Integration - Implement _submit_to_marketplace() with HTTP client to coordinator API - Implement _update_marketplace_offer() with HTTP client - Implement assess_capabilities() with GPU detection using nvidia-smi - Add coordinator_url parameter and AITBCHTTPClient integration Phase 2: Agent SDK Network Registration - Implement register_with_network() with HTTP client to coordinator API - Implement get_reputation() with HTTP client to fetch from API - Implement get_earnings() with HTTP client to fetch from API - Implement signature verification in send_message() and receive_message() - Add coordinator_url parameter and AITBCHTTPClient integration Phase 3: Coordinator API Enterprise Integration - Implement generic ERPIntegration base class methods with mock implementations - Implement generic CRMIntegration base class methods with mock implementations - Add BillingIntegration base class with generic mock implementations - Add ComplianceIntegration base class with generic mock implementations - No third-party integration as requested Phase 4: Coordinator API Key Management - Add MockHSMStorage class with in-memory key storage - Add HSMProviderInterface with mock HSM connection methods - FileKeyStorage already had all abstract methods implemented Phase 5: Blockchain Node Multi-Chain Operations - Implement start_chain() with Ethereum-specific chain startup - Implement stop_chain() with Ethereum-specific chain shutdown - Implement sync_chain() with Ethereum consensus (longest-chain rule) - Add database, RPC server, P2P service, and consensus initialization Phase 6: Settlement Bridge - Implement EthereumBridge class extending BridgeAdapter - Implement _encode_payload() with Ethereum transaction encoding - Implement _get_gas_estimate() with Web3 client integration - Add Web3 client initialization and gas estimation with safety buffer
