This study introduces a low-level blockchain marketplace for sharing power generation and demand using Internet of Things (IoT) devices. A lightweight consensus protocol enables feasibility for secure, decentralized energy data management.
Area of Science:
- Computer Science
- Electrical Engineering
- Energy Systems
Background:
- Decentralized energy systems require secure and efficient data sharing mechanisms.
- Existing blockchain solutions may be too resource-intensive for low-power devices.
Purpose of the Study:
- To propose and validate a low-level blockchain marketplace for peer-to-peer energy trading.
- To enable Internet of Things (IoT) devices to function as both data generators and blockchain nodes.
Main Methods:
- Development of a lightweight blockchain with a specific consensus protocol.
- Integration of IoT devices for real-time power generation and demand data collection.
- Utilization of Smart Contracts for managing energy data and transactions.
Main Results:
- Demonstrated the technical feasibility of a blockchain marketplace on low-performance devices.
- Confirmed that IoT devices can simultaneously collect data and participate in blockchain consensus.
- Smart Contracts effectively managed power generation and demand registrations.
Conclusions:
- A lightweight blockchain approach is viable for decentralized energy marketplaces.
- The proposed system enables secure and efficient data sharing for IoT-enabled energy networks.
- This architecture supports integration with external services for advanced energy management.
