Crypto-Trading. Rechargeable Token-Based Smart Energy Market Enabled by Blockchain and IoT Technology

This paper presents the definition and the implementation of a decentralized system for the energy trading managed by blockchain technology. The system, called Crypto-Trading, is composed by three interacting subsystems: the trading platform, the blockchain, and the smart meters system. It is conceived to exploit the IoT technology of smart meters and the decentralization of smart contracts working inside the blockchain technology for managing exchange and trading of energy by means of specific tokens. The paper defines the system as a decentralized application, identifying system actors and describing user stories. Then provides the description of the use case concerning the rechargeable token, one of the main feature of our system, and its interaction with the other components of the system. Finally, the paper compares our implementation choice with other ongoing projects in the field of energy trading.
