[Contract] 📂 Peer to Peer Energy

[salazarsebas]

🎯 Objective

Create a complete smart contract for peer-to-peer-energy-sharing that enables direct energy sharing between prosumers on the Stellar network using Soroban, facilitating decentralized energy transactions with secure payments.

🏗 Contract Structure

peer-to-peer-energy-sharing/src/
  lib.rs                // Configuration and contract exports
  sharing.rs            // Core logic for energy sharing transactions
  payment.rs            // Payment processing for energy transfers
  utils.rs              // Shared utilities for validation and metering
  Makefile              // Build and deployment automation
  README.md             // Contract documentation and usage instructions

🗂 Requirements

1. Energy Sharing

   • Implement mechanisms for peer-to-peer energy transfers, compliant with energy trading regulations.
   • Support real-time energy sharing and payment settlement.
   • Enable verification of energy delivery via smart meter data.

2. Energy-Specific Features

   • Role-based access: Prosumers as both producers and consumers.
   • Integration hooks for linking to smart meter data or energy trading contracts.

3. Build and Test

   • Must successfully execute cargo build, stellar contract build, and cargo test.

📦 Key Data Structures

The contract will use maps to associate prosumer addresses with energy sharing agreements, detailing energy amounts, prices, and delivery timestamps. A separate structure will log completed transactions, including sender, receiver, and payment details, for transparency and auditability.

🔑 Key Functions

• initialize() – Set up the contract with prosumer roles and sharing rules.
• create_agreement() – Establish an energy sharing agreement between prosumers.
• deliver_energy() – Record energy delivery with meter verification.
• settle_payment() – Execute payment for delivered energy.
• get_transaction_history() – Query the history of energy sharing transactions.

📌 Additional Notes

• Optimize storage to minimize transaction fees on Soroban for prosumers.
• Design for scalability to handle frequent energy sharing transactions.
• Ensure secure payment and delivery verification to maintain trust.
• Support future integration with smart meter data feeds.
• Include mechanisms for resolving disputes in energy delivery.
