Abstract

Blockchain technology has gained a lot of attention in the last few years due to its great potential. Indeed, this technology can be seen as a trusted ledger that allows different parties that do not necessarily trust each other to interact over the Internet without the need for trusted third parties like banks or other types of institutions. To do so, the blockchain is implemented as a distributed network where each participant within the network maintains, approves and updates new entries. Meanwhile, the concept of renewable energy community is developing as a way to promote green energies. This concept enables closely related prosumers and consumers to directly exchange energy. In this context, this work investigates how the blockchain technology can improve the current implementation of the WeSmart company that handles a renewable energy community. More precisely, this work focuses on two objectives. It first explores the possibility to use a blockchain to facilitate the energy trading and exchange between the participants of a renewable energy community. In a second time, the paper concentrates on the use of a blockchain to ensure the integrity of the WeSmart data stored in the cloud. A concrete implementation using the Hyperledger Sawtooth tool is presented and the performances of the solution are analyzed.
