This commit implements a complete blockchain-based plant tracking system that preserves lineage across clones, seeds, and all plant offspring while connecting growers through geographic proximity. Features implemented: - Custom blockchain with proof-of-work consensus - Plant registration and cloning with lineage tracking - Geographic discovery to find nearby plants and growers - Integration with plants.net API for plant identification - Comprehensive web UI for plant management - RESTful API endpoints for all operations - Network statistics and visualization Core Components: - lib/blockchain/: PlantBlock, PlantChain, and blockchain manager - lib/services/: plants.net API and geolocation services - pages/api/plants/: REST API endpoints for all operations - pages/: Frontend UI pages for registration, exploration, and lineage Technical Details: - TypeScript for type safety - Next.js for server-side rendering - Tailwind CSS for responsive design - JSON file-based blockchain storage - Haversine distance calculations for geolocation - OpenStreetMap integration for geocoding This system enables large-scale adoption by: - Making plant lineage tracking accessible to everyone - Connecting local communities through plant sharing - Providing immutable proof of plant provenance - Supporting unlimited generations of plant propagation - Scaling from individual growers to global networks Documentation includes comprehensive README with: - Quick start guide - API reference - Architecture details - Scaling recommendations - Use cases for various audiences - Roadmap for future enhancements
