Each device type will have a dedicated adapter class implementing the `Device` interface with methods: `connect()`, `get_power_reading()`, `get_energy_reading()`, `get_device_info()`, `disconnect()`. | +| 2. | **Unified Device Interface** | Create abstract base class `DeviceAdapter` in `backend/src/devices/base.py` that defines standard interface for all device types. Implement **auto-discovery protocol** that scans local network for supported devices (using mDNS/SSDP). Build **device capability detection** system that queries device for supported features (power monitoring, control, scheduling). Implement **connection health monitoring** with automatic reconnection logic and exponential backoff. Provide **device metadata** standardization (MAC address, IP, firmware version, capabilities). | +| 3. | **Configuration System** | Extend `backend/config/` to support multi-device configuration via YAML/JSON files. Format: `devices.yaml` with array of device configs (type, connection details, polling intervals). Implement **environment variable override** system for sensitive data (passwords, API keys). Build **encrypted credential storage** using `cryptography` library with key derivation from environment variable. Create **device profile templates** for common setups (e.g., "4-plug home", "EV charging", "HVAC control"). | +| 4. | **Enhanced Oracle Service** | Refactor `backend/src/oracle_service.py` to support **10+ simultaneous devices** with concurrent polling (async I/O). Implement **round-robin polling** with configurable intervals per device type (fast: 30s, slow: 5min). Build **device-specific error handling** (e.g., WiFi drops, API rate limits, firmware bugs). Create **logging per device instance** with structured logs (JSON format) for debugging. Implement **graceful degradation** where oracle continues with working devices if some fail. Add **device statistics tracking** (uptime, error rate, data quality). | +| 5. | **Basic Web Interface** | Build simple React web app (no wallet integration yet) with following views: **Device List View**: Shows all registered devices with status (online/offline), current power draw, and last update time. **Real-time Monitoring**: Live charts showing power consumption over last 24 hours per device. **Device Management**: Add/remove devices via web form (stores in database, not blockchain yet). **System Status**: Oracle health, blockchain connection, database stats. **Basic REST API**: FastAPI endpoints for device CRUD operations and status queries. Responsive design (mobile-friendly). Deployment: Dockerized with Nginx reverse proxy. | + +**Acceptance Criteria:** +- Oracle service successfully managing 10+ devices concurrently for 24+ hours +- All 10 device types have passing integration tests +- Basic web interface deployed and accessible via browser +- Documentation includes step-by-step guide for adding 11th device type +- Repository includes example configurations for 5+ common device setups + +--- + +### Milestone 4 — Production Features & Full Dashboard + +**Goal:** Implement production-grade features including multi-oracle architecture, security hardening, and complete web dashboard with wallet integration. + +- **Estimated Duration:** 2 months +- **FTE:** 1.5 +- **Costs:** $10,000 USD + +| Number | Deliverable | Specification | +| -----: | ----------- | ------------- | +| **0a.** | License | MIT | +| **0b.** | Documentation | **System architecture diagrams** (oracle coordination, contract interactions) + **API specification** (OpenAPI 3.0 format) + **Deployment guide** for production environment (cloud providers, security best practices) + **Security documentation** (threat model, mitigation strategies).

Guide covers running performance benchmarks and security scans. Target: 90%+ code coverage. See [delivery guidelines](https://grants.web3.foundation/docs/Support%20Docs/milestone-deliverables-guidelines#testing-guide). | +| **0d.** | Docker | Production-ready `docker-compose.prod.yml` with health checks, resource limits, logging configuration, and secrets management. Includes monitoring stack (Prometheus + Grafana) for oracle/API metrics. | +| **0e.** | Article | Medium article: **"Building Production DePIN: Multi-Oracle Architecture & Security Best Practices"** covering oracle coordination algorithms, Byzantine fault tolerance implementation, security hardening process, and performance optimization lessons. | +| 1. | **Multi-Oracle Architecture** | Implement **3+ oracle instances** coordinating via smart contracts (not peer-to-peer). Design: Each oracle submits device data with signature → Grid Service Contract validates oracle signatures → Contract requires **2-of-3 consensus** before accepting data submission → Rewards distributed proportionally to participating oracles. Build **oracle reputation system**: Track submission accuracy, uptime, response time → Slash rewards for consistent failures → Auto-disable oracles below threshold. Implement **automatic failover**: If primary oracle misses 3 submissions, secondary takes over → Smart contract tracks active oracle set → Rotation algorithm prevents single points of failure. Add **oracle registration contract** for permissionless oracle operation (future community participation). Test Byzantine scenarios: Oracle submitting false data, colluding oracles, network partitions. | +| 2. | **Smart Contract Enhancements** | Implement **emergency pause functionality**: Admin multisig can pause contracts in case of exploit → Unpause requires timelock → Events emitted for transparency. Build **contract upgrade mechanism**: Transparent proxy pattern (ERC1967-style) → Upgrade requires governance proposal + timelock → Old contract data migrates to new implementation. Optimize **reward calculation**: Batch reward distribution to reduce gas costs → Merkle tree proof system for large reward sets → Off-chain computation with on-chain verification. Implement **slashing conditions**: Slash oracle stake for Byzantine behavior → Slash device stake for false participation claims → Graduated penalties (warning → small slash → full slash → ban). Reduce **gas costs**: Pack struct fields efficiently → Use events instead of storage where possible → Batch operations where applicable. All changes include comprehensive tests and gas benchmarks. | +| 3. | **Full Web Dashboard** | Build production-ready React web app with: **Wallet Integration**: Polkadot.js extension, SubWallet, Talisman wallet → Account selection → Balance display (DOT + PWGD). **Device Registration**: User stakes PWGD tokens → Registers device on-chain → Shows transaction status and confirmation. **Real-time Earnings Tracker**: Current PWGD balance → Earnings breakdown (per device, per event) → Historical earnings chart → Next reward estimate. **Event Participation History**: List of past grid events → Participation status per event → Energy contributed + rewards earned → Filter/search functionality. **Reputation Score Display**: User's current reputation (0-100) → Reputation impact on rewards (multiplier) → Tips for improving reputation. **Analytics Dashboard**: Energy consumption patterns (daily/weekly/monthly) → Cost savings estimate → Carbon footprint reduction → Community comparison (anonymized leaderboards). **Responsive Design**: Mobile-first approach → Touch-friendly controls → Progressive Web App (PWA) features. **Error Handling**: User-friendly error messages → Transaction status tracking → Retry mechanisms for failed blockchain interactions. | +| 4. | **Security Hardening** | Implement comprehensive security measures: **Input Validation**: Sanitize all user inputs → Prevent SQL injection, XSS, command injection → Rate limiting on all API endpoints. **Authentication**: JWT-based auth for API → Wallet signature verification → Session management with secure cookies. **Secure Credential Storage**: Use HashiCorp Vault or encrypted environment variables → Never log sensitive data → Rotate API keys regularly. **Database Security**: Prepared statements for all queries → Least privilege database users → Encrypted connections (SSL/TLS). **API Security**: CORS configuration → HTTPS enforcement → API key rotation mechanism. **Smart Contract Security**: Reentrancy guards on all payable functions → Integer overflow checks → Access control on admin functions → Emergency circuit breakers. **Dependency Management**: Regular security audits of dependencies → Automated vulnerability scanning (GitHub Dependabot) → Pin dependency versions. **Security Testing**: OWASP Top 10 testing → Automated security scans (Bandit for Python, Slither for contracts) → Manual penetration testing of critical flows. Document all security measures and prepare for external audit in M5. | +| 5. | **Performance Optimization** | Optimize system to handle **100+ simultaneous devices**: **Database Optimization**: Add indexes on frequently queried columns → Implement connection pooling → Use read replicas for analytics queries → Partition large tables by timestamp. **Caching Strategy**: Redis cache for device status → TTL-based invalidation → Cache warming on oracle startup → Cache stampede prevention. **API Performance**: Implement pagination on all list endpoints → Use database cursors for large datasets → Compress API responses (gzip) → Implement HTTP ETag for conditional requests. **WebSocket Optimization**: Use WebSocket for real-time updates instead of polling → Connection pooling → Automatic reconnection with exponential backoff. **Blockchain Batching**: Batch device data submissions (submit 10 devices per transaction instead of 1) → Use contract events efficiently → Optimize RPC call patterns. **Monitoring**: Prometheus metrics for all services → Grafana dashboards for visualization → Alert rules for critical issues (oracle down, database full, high API latency). **Performance Targets**: API response time < 200ms (95th percentile) → Device data submission < 5s from reading to on-chain → Support 100 devices with single oracle instance → Web dashboard load time < 2s. Conduct load testing with k6 or Locust and document results. | +| 6. | **Advanced Analytics** | Build analytics features: **Earnings Projections**: ML model (simple linear regression) trained on historical participation → Predict next month's earnings → Show confidence intervals → Update predictions weekly. **Carbon Footprint Calculator**: Calculate CO2 reduction based on energy shifted → Use grid carbon intensity data (by region/time) → Show cumulative lifetime impact → Compare with community average. **Community Leaderboards**: Top earners (anonymized usernames) → Most consistent participants → Best reputation scores → Device type comparisons. **Device Performance Comparison**: Compare user's devices against network average → Identify underperforming devices → Suggest optimization actions. **Grid Event Insights**: Show participation rate for past events → Peak demand periods → Most lucrative event times → Historical reward trends. All analytics respect user privacy (no PII shared, opt-in for leaderboards). | + +**Acceptance Criteria:** +- Multi-oracle system successfully coordinating for 7+ days with Byzantine fault injection tests passing +- Web dashboard fully functional with 3+ wallet types +- System sustaining 100+ concurrent devices with <200ms API latency +- Security documentation complete and ready for external audit +- Performance benchmarks meeting specified targets + +--- + +### Milestone 5 — Documentation, SDK & Community Tooling + +**Goal:** Make PowerGrid Network accessible to developers, users, and utility partners through comprehensive documentation, SDKs, video tutorials, and integration tools. + +- **Estimated Duration:** 2 months +- **FTE:** 1.5 +- **Costs:** $10,000 USD + +| Number | Deliverable | Specification | +| -----: | ----------- | ------------- | +| **0a.** | License | MIT | +| **0b.** | Documentation | **Complete documentation site** hosted at docs.powergrid.network (or subdomain) with search functionality, version control, and mobile-responsive design.
