# 🧅 Tor Integration Guide for LocalGreenChain
|
||||
|
||||
This guide explains how to set up LocalGreenChain with Tor for maximum privacy and anonymity when sharing plant lineages.
|
||||
|
||||
## Why Use Tor with LocalGreenChain?
|
||||
|
||||
### Privacy Benefits
|
||||
- **Anonymous Plant Registration**: Register plants without revealing your identity
|
||||
- **Location Privacy**: Share general area without exposing exact home address
|
||||
- **IP Protection**: Hide your IP address from other users and the network
|
||||
- **Censorship Resistance**: Access the network even in restrictive environments
|
||||
- **Secure Sharing**: Share plant clones with trusted community members anonymously
|
||||
|
||||
### Use Cases
|
||||
- **Privacy-Conscious Growers**: Don't want to advertise exact plant locations
|
||||
- **Sensitive Species**: Medicinal plants, rare species, or regulated botanicals
|
||||
- **Community Building**: Connect with local growers without revealing identity
|
||||
- **Research**: Anonymous data collection for botanical research
|
||||
- **Security**: Protect against unwanted visitors or theft

### Option 1: Docker Compose (Recommended)
|
||||
|
||||
The easiest way to run LocalGreenChain with Tor:
|
||||
|
||||
```bash
|
||||
# Copy environment variables
|
||||
cp .env.example .env
|
||||
|
||||
# Edit .env and enable Tor
|
||||
nano .env
|
||||
# Set: TOR_ENABLED=true
|
||||
|
||||
# Start with Docker Compose
|
||||
docker-compose -f docker-compose.tor.yml up -d
|
||||
|
||||
# Check if Tor is running
|
||||
docker logs localgreenchain-tor
|
||||
|
||||
# Get your onion address
|
||||
docker exec localgreenchain-tor cat /var/lib/tor/hidden_service/hostname
|
||||
```
|
||||
|
||||
Your LocalGreenChain instance is now accessible via:
|
||||
- Local: http://localhost:3001
|
||||
- Onion: http://[your-address].onion (share this!)
|
||||
|
||||
### Option 2: Manual Installation
|
||||
|
||||
1. **Install Tor**
|
||||
2. **Configure Tor for LocalGreenChain**
|
||||
3. **Start LocalGreenChain with Tor enabled**

|
||||
|
||||
## Running as Hidden Service
|
||||
|
||||
### Start LocalGreenChain
|
||||
|
||||
```bash
|
||||
# Install dependencies
|
||||
bun install
|
||||
|
||||
# Start in production mode
|
||||
bun run build
|
||||
bun run start
|
||||
|
||||
# Or development mode
|
||||
bun run dev
|
||||
```
|
||||
|
||||
### Verify Hidden Service
|
||||
|
||||
```bash
|
||||
# Check if Tor created keys
|
||||
ls -la /var/lib/tor/localgreenchain/
|
||||
|
||||
# Should see:
|
||||
# - hostname (your .onion address)
|
||||
# - hs_ed25519_public_key
|
||||
# - hs_ed25519_secret_key
|
||||
|
||||
# Get your onion address
|
||||
cat /var/lib/tor/localgreenchain/hostname
|
||||
```
|
||||
|
||||
### Share Your Onion Address
|
||||
|
||||
Your `.onion` address looks like:
|
||||
```
|
||||
abc123def456ghi789.onion
|
||||
```
|
||||
|
||||
Share this with trusted community members to allow anonymous access!
|
||||
|
||||
---
|
||||
|
||||
## Using Tor Browser
|
||||
|
||||
### As a User (Accessing LocalGreenChain via Tor)
|
||||
|
||||
1. **Download Tor Browser**
|
||||
- Visit: https://www.torproject.org/download/
|
||||
- Install for your operating system
|
||||
|
||||
2. **Connect to Tor Network**
|
||||
- Launch Tor Browser
|
||||
- Click "Connect" to establish Tor connection
|
||||
|
||||
3. **Access LocalGreenChain**
|
||||
- Option A: Via onion address (recommended)
|
||||
```
|
||||
http://[your-onion-address].onion
|
||||
```
|
||||
- Option B: Via clearnet (still anonymous)
|
||||
```
|
||||
http://your-domain.com
|
||||
```
|
||||
|
||||
4. **Register Plants Anonymously**
|
||||
- Go to "Anonymous Registration" page
|
||||
- Your connection will be detected as coming from Tor
|
||||
- All privacy features automatically enabled
|
||||
|
||||
### Privacy Indicators
|
||||
|
||||
LocalGreenChain will show you:
|
||||
- 🧅 "Tor Active" badge when connected via Tor
|
||||
- Privacy recommendations based on connection type
|
||||
- Tor circuit information (country, not your IP)
|
||||
|
||||
---
|
||||
|
||||
## Privacy Best Practices
|
||||
|
||||
### For Maximum Anonymity
|
||||
|
||||
1. **Always Use Tor Browser**
|
||||
- Don't access via regular browser
|
||||
- Tor Browser includes additional privacy protections
|
||||
|
||||
2. **Enable Anonymous Mode**
|
||||
- Use `/plants/register-anonymous` page
|
||||
- Generate random IDs and pseudonyms
|
||||
- Don't reuse usernames from other sites
|
||||
|
||||
3. **Location Privacy**
|
||||
- Use "Fuzzy" or "City" level location sharing
|
||||
- Never share exact coordinates
|
||||
- Consider using "Hidden" for sensitive plants
|
||||
|
||||
4. **Operational Security (OpSec)**
|
||||
- Don't include identifiable info in plant notes
|
||||
- Use different pseudonyms for different plant types
|
||||
- Don't correlate with social media accounts
|
||||
- Clear browser data after each session
|
||||
|
||||
5. **Network Security**
|
||||
- Only share your .onion address with trusted people
|
||||
- Use secure channels (encrypted messaging) to share addresses
|
||||
- Rotate your hidden service periodically if needed
|
||||
|
||||
### Privacy Levels Explained
|
||||
|
||||
| Level | Location Accuracy | Best For |
|
||||
|-------|------------------|----------|
|
||||
| **Exact** | ~100m | Public gardens, commercial nurseries |
|
||||
| **Fuzzy** | 1-5km radius | Home gardens, privacy-conscious sharing |
|
||||
| **City** | ~10km grid | Regional plant trading |
|
||||
| **Country** | ~100km grid | National distribution tracking |
|
||||
| **Hidden** | No location | Maximum privacy, sensitive species |
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Tor Won't Start
|
||||
|
||||
```bash
|
||||
# Check Tor status
|
||||
sudo systemctl status tor
|
||||
|
||||
# View logs
|
||||
sudo tail -f /var/log/tor/notices.log
|
||||
|
||||
# Common issues:
|
||||
# 1. Port 9050 already in use
|
||||
sudo lsof -i :9050
|
||||
|
||||
# 2. Permission issues
|
||||
sudo chown -R debian-tor:debian-tor /var/lib/tor
|
||||
sudo chmod 700 /var/lib/tor/localgreenchain
|
||||
```
|
||||
|
||||
### Hidden Service Not Accessible
|
||||
|
||||
```bash
|
||||
# Verify Tor is running
|
||||
pgrep tor
|
||||
|
||||
# Check if hostname file exists
|
||||
cat /var/lib/tor/localgreenchain/hostname
|
||||
|
||||
# Verify LocalGreenChain is running
|
||||
curl http://localhost:3001
|
||||
|
||||
# Check Tor logs for errors
|
||||
sudo tail -f /var/log/tor/notices.log
|
||||
```
|
||||
|
||||
### "Tor Status: Not Available"
|
||||
|
||||
1. Check if Tor daemon is running
|
||||
2. Verify SOCKS port (9050) is open
|
||||
3. Check firewall settings
|
||||
4. Restart Tor service
|
||||
|
||||
```bash
|
||||
sudo systemctl restart tor
|
||||
```
|
||||
|
||||
### Slow Onion Connection
|
||||
|
||||
This is normal! Tor routes through multiple nodes:
|
||||
- First connection: 30-60 seconds
|
||||
- Subsequent loads: 5-15 seconds
|
||||
- Plant operations: Near instant (local blockchain)
|
||||
|
||||

|
||||
|
||||
## Advanced Topics
|
||||
|
||||
### Running Multiple Hidden Services
|
||||
|
||||
Edit `/etc/tor/torrc`:
|
||||
|
||||
```
|
||||
# LocalGreenChain (public)
|
||||
HiddenServiceDir /var/lib/tor/localgreenchain-public/
|
||||
HiddenServicePort 80 127.0.0.1:3001
|
||||
|
||||
# LocalGreenChain (private - invite only)
|
||||
HiddenServiceDir /var/lib/tor/localgreenchain-private/
|
||||
HiddenServicePort 80 127.0.0.1:3002
|
||||
```
|
||||
|
||||
### Client Authentication (v3 Onions)
|
||||
|
||||
Restrict access to authorized users only:
|
||||
|
||||
```
|
||||
# In torrc
|
||||
HiddenServiceDir /var/lib/tor/localgreenchain/
|
||||
HiddenServicePort 80 127.0.0.1:3001
|
||||
HiddenServiceAuthorizeClient stealth alice,bob
|
||||
```
|
||||
|
||||
### Monitoring Tor Traffic
|
||||
|
||||
```bash
|
||||
# Real-time connection monitoring
|
||||
sudo nyx
|
||||
|
||||
# Or arm (older tool)
|
||||
sudo arm
|
||||
```
|
||||
|
||||
### Backup Your Hidden Service Keys
|
||||
|
||||
**IMPORTANT**: Your `.onion` address is tied to your keys!
|
||||
|
||||
```bash
|
||||
# Backup keys
|
||||
sudo cp -r /var/lib/tor/localgreenchain ~/tor-backup/
|
||||
|
||||
# Restore keys (on new server)
|
||||
sudo cp -r ~/tor-backup/* /var/lib/tor/localgreenchain/
|
||||
sudo chown -R debian-tor:debian-tor /var/lib/tor/localgreenchain
|
||||
sudo systemctl restart tor
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Security Considerations
|
||||
|
||||
### What Tor DOES Protect
|
||||
✅ Your IP address from other users
|
||||
✅ Your browsing from your ISP
|
||||
✅ Your location from the network
|
||||
✅ Your identity when using anonymous mode
|
||||
|
||||
### What Tor DOESN'T Protect
|
||||
❌ Poor operational security (sharing identifying info)
|
||||
❌ Malware on your computer
|
||||
❌ Logging in with real accounts
|
||||
❌ Data you voluntarily share
|
||||
|
||||
### Remember
|
||||
- **Tor provides anonymity, not security**
|
||||
- Use HTTPS even over Tor (LocalGreenChain supports this)
|
||||
- Don't mix anonymous and identified activities
|
||||
- Keep Tor Browser up to date
|
||||
- Trust the process - Tor has protected millions of users

## Legal Notice
|
||||
|
||||
Using Tor is legal in most countries. However:
|
||||
- Check local laws regarding Tor usage
|
||||
- Using Tor for illegal activities is still illegal
|
||||
- LocalGreenChain is for botanical education and legal plant sharing
|
||||
- Respect plant import/export regulations
|
||||
- Some plants may be regulated or controlled substances
