Configuration

Key settings in node.toml for service providers:

[node]
chain_id = "supernova-mainnet"
environment = "Production"
metrics_enabled = true

[network]
listen_addr = "/ip4/0.0.0.0/tcp/8000"
max_peers = 100
connection_timeout = 30

[api]
bind_address = "127.0.0.1"  # Change to 0.0.0.0 to allow external connections
port = 8080
enable_auth = true

[wallet]
enable = true
auto_backup = true
backup_interval_hours = 24

Security Recommendations

• Run the node on a dedicated server with firewall
• Limit API access using enable_auth and API keys
• Use a reverse proxy (like Nginx) for TLS termination
• Set up monitoring and alerts

Basic Integration

Address Generation

SuperNova uses standard Bitcoin-compatible addresses with optional quantum-resistant extensions.

Classical Addresses

For basic integration, you can use classical addresses which start with "sn1" (for mainnet) or "snt1" (for testnet).

Example API call to generate a new address:

curl -X POST "https://node.supernova.io/api/v1/wallet/addresses/new" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "label": "Customer deposit address",
    "type": "receive"
  }'

Response:

{
  "success": true,
  "data": {
    "address": "sn1qkl4hvc5zw8ru6tpzj2lf0u4s5jx9rgwep2j5d5",
    "type": "receive",
    "hd_path": "m/84'/0'/0'/0/1",
    "label": "Customer deposit address"
  }
}

Quantum-resistant Addresses

For future-proof security, you can use quantum-resistant addresses which start with "snq" (for mainnet) or "sntq" (for testnet).

curl -X POST "https://node.supernova.io/api/v1/wallet/addresses/new" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "label": "Customer deposit address",
    "type": "receive",
    "quantum_resistant": true
  }'

Response:

{
  "success": true,
  "data": {
    "address": "snq1q9z5z9wygy0yt2l94rzp6rh89w703c8k37q3urp8r8s9w97hr7j88s5mht0",
    "type": "receive",
    "hd_path": "m/84'/0'/0'/0/1",
    "label": "Customer deposit address",
    "quantum_resistant": true
  }
}

Deposit Detection

To detect incoming deposits, you can:

1. Subscribe to WebSocket notifications (recommended)
2. Poll the API for new transactions

WebSocket Subscription

const WebSocket = require('ws');
const ws = new WebSocket('wss://node.supernova.io/api/v1/ws');

ws.on('open', function open() {
  ws.send(JSON.stringify({
    type: 'subscribe',
    channel: 'address_transactions',
    addresses: ['sn1qkl4hvc5zw8ru6tpzj2lf0u4s5jx9rgwep2j5d5']
  }));
});

ws.on('message', function incoming(data) {
  const message = JSON.parse(data);
  if (message.type === 'transaction') {
    console.log('New transaction:', message.data);
    // Process deposit
  }
});

Polling API

async function checkForDeposits() {
  const response = await fetch('https://node.supernova.io/api/v1/wallet/transactions?limit=10', {
    headers: {
      'Authorization': 'Bearer YOUR_API_KEY'
    }
  });
  
  const data = await response.json();
  
  if (data.success) {
    // Process new transactions
    for (const tx of data.data.transactions) {
      if (tx.category === 'receive' && tx.confirmations >= 6) {
        console.log('Confirmed deposit:', tx);
        // Process deposit
      }
    }
  }
}

// Poll every minute
setInterval(checkForDeposits, 60000);

Processing Withdrawals

To process withdrawals, create and send transactions:

curl -X POST "https://node.supernova.io/api/v1/wallet/send" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "outputs": [
      {
        "address": "sn1q9h6s5m7p4euj6h9g5tc9qxt6azqzs9t4f5nc59",
        "amount": 5000000
      }
    ],
    "fee_rate": 10,
    "subtract_fee_from_amount": false,
    "replaceable": true,
    "comment": "Customer withdrawal"
  }'

Response:

{
  "success": true,
  "data": {
    "txid": "7f2c3a7e4d5b6c8d9e0f1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d",

}

Advanced Features

Quantum-resistant Signatures

SuperNova supports two post-quantum signature schemes:

1. Dilithium - For standard transactions
2. Falcon - For applications requiring smaller signatures

To specify the quantum signature scheme when creating a transaction:

{
  "outputs": [...],
  "quantum_signature": {
    "scheme": "dilithium",
    "strength": "medium"  // "low", "medium", or "high"
  }
}

Environmental Impact

SuperNova includes comprehensive environmental impact tracking:

curl -X GET "https://node.supernova.io/api/v1/stats/environmental" \
  -H "Authorization: Bearer YOUR_API_KEY"

To show users transaction carbon footprint:

async function getTransactionFootprint(txid) {
  const response = await fetch(`https://node.supernova.io/api/v1/wallet/transactions/${txid}`, {
    headers: {
      'Authorization': 'Bearer YOUR_API_KEY'
    }
  });
  
  const data = await response.json();
  
  if (data.success) {
    return {
      emissions_gCO2: data.data.carbon_footprint.emissions_gCO2,
      energy_consumption_kWh: data.data.carbon_footprint.energy_consumption_kWh
    };
  }
  
  return null;
}

Lightning Network

SuperNova includes full Lightning Network support for fast, off-chain transactions:

# Create a lightning invoice
curl -X POST "https://node.supernova.io/api/v1/wallet/lightning/create-invoice" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "amount": 100000,
    "description": "Coffee payment"
  }'

Response:

{
  "success": true,
  "data": {
    "payment_request": "lnsn1qcp4256yw...",
    "created_at": "2025-04-15T12:34:56Z",
    "expires_at": "2025-04-15T13:34:56Z",
    "amount": 100000,
    "description": "Coffee payment",
    "payment_hash": "a1b2c3d4e5f6...",
    "carbon_footprint": {
      "emissions_gCO2": 0.0002,
      "energy_consumption_kWh": 0.0000006
    }
  }
}
