# 🌱 LocalGreenChain
|
||||
|
||||
An example marketing site built using Drupal + JSON:API.
|
||||
**A blockchain for plants that preserves lineage across clones and seeds, connecting growers worldwide.**
|
||||
|
||||
Pages are built from the Landing page node type and paragraphs sourced from `/drupal`.
|
||||
LocalGreenChain is a revolutionary plant tracking system that uses blockchain technology to create an immutable record of plant lineage. Track every clone, cutting, seed, and offspring throughout multiple generations while connecting with nearby growers who share your passion for plants.
|
||||
|
||||
See https://demo.next-drupal.org
|
||||
## ✨ Features
|
||||
|
||||
## License
|
||||
### 🌳 **Lineage Tracking**
|
||||
- Track every plant from its origin through unlimited generations
|
||||
- Record propagation methods (clone, seed, cutting, division, grafting)
|
||||
- Build comprehensive family trees showing ancestors, descendants, and siblings
|
||||
- Immutable blockchain ensures lineage data can never be lost or altered
|
||||
|
||||

|
||||
- See global distribution statistics by species and location
|
||||
- Join a worldwide community of plant enthusiasts
|
||||
|
||||
### 🎨 **User-Friendly Interface**
|
||||
- Beautiful, intuitive web interface
|
||||
- Easy plant registration with geolocation support
|
||||
- Visual lineage explorer
|
||||
- Network statistics dashboard
|
||||
- Mobile-responsive design
|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
### Prerequisites
|
||||
- Node.js 14+ and npm/yarn
|
||||
- Basic knowledge of plant propagation (optional but helpful!)
|
||||
|
||||
### Installation
|
||||
|
||||
1. **Clone the repository**
|
||||
```bash
|
||||
git clone https://github.com/yourusername/localgreenchain.git
|
||||
cd localgreenchain
|
||||
```
|
||||
|
||||
2. **Install dependencies**
|
||||
```bash
|
||||
npm install
|
||||
# or
|
||||
yarn install
|
||||
```
|
||||
|
||||
3. **Set up environment variables** (optional)
|
||||
```bash
|
||||
cp .env.example .env
|
||||
```
|
||||
|
||||
Edit `.env` and add your plants.net API key if you have one:
|
||||
```
|
||||
PLANTS_NET_API_KEY=your_api_key_here
|
||||
```
|
||||
|
||||
4. **Run the development server**
|
||||
```bash
|
||||
npm run dev
|
||||
# or
|
||||
yarn dev
|
||||
```
|
||||
|
||||
5. **Open your browser**
|
||||
Navigate to [http://localhost:3001](http://localhost:3001)
|
||||
|
||||
## 📖 How It Works
|
||||
|
||||
### The Blockchain
|
||||
|
||||
LocalGreenChain uses a custom blockchain implementation where:
|
||||
|
||||
- **Each block** represents a plant registration or update
|
||||
- **Proof-of-work** mining ensures data integrity
|
||||
- **Cryptographic hashing** links blocks together
|
||||
- **Genesis block** initializes the chain
|
||||
|
||||
### Plant Lineage System
|
||||
|
||||
```
|
||||
Original Plant (Generation 0)
|
||||
├── Clone 1 (Generation 1)
|
||||
│ ├── Seed 1-1 (Generation 2)
|
||||
│ └── Cutting 1-2 (Generation 2)
|
||||
├── Clone 2 (Generation 1)
|
||||
└── Seed 3 (Generation 1)
|
||||
└── Clone 3-1 (Generation 2)
|
||||
```
|
||||
|
||||
Every plant maintains:
|
||||
- **Parent reference**: Which plant it came from
|
||||
- **Children array**: All offspring created from it
|
||||
- **Generation number**: How many steps from the original
|
||||
- **Propagation type**: How it was created
|
||||
|
||||
### Geographic Discovery
|
||||
|
||||
The system calculates distances between plants using the Haversine formula to:
|
||||
- Find plants within a specified radius
|
||||
- Cluster nearby plants to show hotspots
|
||||
- Suggest connections based on proximity and species
|
||||
|
||||
## 🎯 Use Cases
|
||||
|
||||
### For Home Gardeners
|
||||
- Track your plant collection and propagation success
|
||||
- Share clones with friends while maintaining the lineage record
|
||||
- Find local gardeners with similar plants for trading
|
||||
|
||||
### For Plant Nurseries
|
||||
- Provide customers with verified lineage information
|
||||
- Track all plants sold and their offspring
|
||||
- Build trust through transparent provenance
|
||||
|
||||
### For Conservation Projects
|
||||
- Document rare plant propagation efforts
|
||||
- Track genetic diversity across populations
|
||||
- Coordinate distribution of endangered species
|
||||
|
||||
### For Community Gardens
|
||||
- Manage shared plant collections
|
||||
- Track plant donations and their spread
|
||||
- Build local food security networks
|
||||
|
||||
### For Research
|
||||
- Study plant propagation success rates
|
||||
- Track genetic drift across generations
|
||||
- Analyze geographic distribution patterns
|
||||
|
||||

## 🌐 Scaling for Mass Adoption
|
||||
|
||||
### Current Implementation
|
||||
- **Single-server blockchain**: Good for 10,000s of plants
|
||||
- **File-based storage**: Simple and portable
|
||||
- **Client-side rendering**: Fast initial setup
|
||||
|
||||
### Scaling Recommendations
|
||||
|
||||
#### For 100,000+ Plants
|
||||
1. **Switch to database**: PostgreSQL or MongoDB
|
||||
2. **Add caching**: Redis for frequently accessed data
|
||||
3. **Optimize mining**: Reduce difficulty or use alternative consensus
|
||||
|
||||
#### For 1,000,000+ Plants
|
||||
1. **Distributed blockchain**: Multiple nodes with consensus
|
||||
2. **Sharding**: Geographic or species-based partitioning
|
||||
3. **CDN**: Serve static content globally
|
||||
4. **API rate limiting**: Protect against abuse
|
||||
|
||||
#### For Global Scale
|
||||
1. **Blockchain network**: Peer-to-peer node system
|
||||
2. **Mobile apps**: Native iOS/Android applications
|
||||
3. **Offline support**: Sync when connection available
|
||||
4. **Federation**: Regional chains with cross-chain references
|
||||
