⚡ Blockchain-Based Peer-to-Peer Energy Trading

This project simulates a decentralized P2P energy trading platform using Ethereum smart contracts, enabling prosumers to trade surplus energy directly with consumers, regulated by a DSO (Distribution System Operator). It is designed for simulation on a local blockchain using Ganache and Web3.py.

🚦 Roles & Responsibilities

Role	Script	Responsibilities
🛠️ DSO	dso.py	Registers nodes, matches trades, verifies transactions
🔋 Prosumer	prosumer.py	Adds funds, injects energy, checks balance
🔌 Consumer	consumer.py	Adds funds, purchase energy, check account balance

All roles interact with the smart contract via Web3.py and log smart contract events.

⚙️ Prerequisites

• Python 3.8+
• Ganache (local Ethereum blockchain)
• Solidity compiler via py-solc-x

---

🔧 Setup Instructions

1. Clone the Repository

git clone https://github.com/Rahil-07/P2P-energy-trading.git
cd P2P-energy-trading

2. Install Python Dependencies

pip install -r requirements.txt

3. Start Ganache

• Start Ganache GUI or run ganache-cli

• Note down the RPC URL and account addresses

4. Configure Addresses

Update config.json with your Ganache addresses and paths:

{
  "contract_path": "./contracts/",
  "build_path": "./build/",
  "dso_address": "0x...",
  "prosumer_address": "0x...",
  "consumer_address": "0x...",
  "contract_address": ""
}

5. Compile & Deploy Contract

python deploy_contract.py EnergyTrading.sol

After successful deployment, the contract address will be written to config.json.

💼 Role-Based Simulation

You can now run the respective scripts for each stakeholder:

🔧 DSO Panel

python dso.py

• Register new nodes

• Match a prosumer with a consumer

• Execute energy trades

• Verify transactions

• View threshold values

🔋 Prosumer Panel

python prosumer.py

• Add funds to wallet

• Inject energy into grid

• View energy and account balances

🔌 Consumer Panel

python consumer.py

• Add funds to wallet

• View owned energy and balance

📜 Smart Contract: EnergyTrading.sol

Written in Solidity 0.6.0, the contract supports:

• Role-based access control

• Ownership and trading of energy units

• Trade matching and verification

• Transparent event logging

Contract ABI and bytecode are stored in build/EnergyTrading/.

🧪 Events Logged

Each interaction emits on-chain events such as:

• OwnershipEvent
• MatchEvent
• EnergyTraded
• BalanceAdded
• EnergyInjected
• TradingLog
• VerificationEvent
• EnergyLossCalculated

These are printed to console for simulation clarity.
