PowerGrid Network - Test Results & Evidence

Complete System Verification

This document provides evidence of the complete working system, from hardware to blockchain.


Setup Instructions (Verified Working)

Step 1: Start Local Node

# Start substrate-contracts-node
~/.local/bin/substrate-contracts-node --dev --tmp --rpc-external --rpc-cors all

Verification:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "peers": 0,
    "isSyncing": false,
    "shouldHavePeers": false
  }
}

✅ Node is running and healthy

Step 2: Deploy Contracts

./scripts/deploy-local.sh

Deployed Contract Addresses:

  • Token: 5FY8e8RtXKDWdeAhnYcBv7TjojDt6NxJNmX7T1TRrZZSZMyk
  • Registry: 5D12ZE2pVZTb3v7RnSMMnf4LPHCAEbcwQWE1TAF9qQiYbFDh
  • Grid Service: 5DW1GhTM696DH4vS5n2zj7L6kFG6t4MVipaEnPKygj48TUtX
  • Governance: 5HdqtBYTtX8KppCxe4ofkFRFR5XTD8uaVCQkXxYhpxGkrTi5

✅ All contracts deployed successfully

Step 3: Configure Oracle with Addresses

Edit backend/.env:

TOKEN_CONTRACT_ADDRESS=5FY8e8RtXKDWdeAhnYcBv7TjojDt6NxJNmX7T1TRrZZSZMyk
REGISTRY_CONTRACT_ADDRESS=5D12ZE2pVZTb3v7RnSMMnf4LPHCAEbcwQWE1TAF9qQiYbFDh
GRID_SERVICE_CONTRACT_ADDRESS=5DW1GhTM696DH4vS5n2zj7L6kFG6t4MVipaEnPKygj48TUtX
GOVERNANCE_CONTRACT_ADDRESS=5HdqtBYTtX8KppCxe4ofkFRFR5XTD8uaVCQkXxYhpxGkrTi5

✅ Configuration complete
