Optimizing Blockchain Based Smart Grid Auctions: A Green Revolution
This paper is a review for researchers in blockchain-based energy auctions, highlighting the need for more computationally efficient and environmentally friendly designs.
This paper reviews existing blockchain-based energy auctions, identifying challenges and future research directions from a 'green' perspective. It does not propose a new method or present new results.
Traditional smart grid energy auctions cannot directly be integrated in blockchain due to its decentralized nature. Therefore, research works are being carried out to propose efficient decentralized auctions for energy trading. Since, blockchain is a novel paradigm which ensures trust, but it also comes up with a curse of high computation and communication complexity which eventually causes resource scarcity. Therefore, there is a need to develop and encourage development of greener and computational-friendly auctions to carry out decentralized energy trading. In this paper, we first provide a thorough motivation of decentralized auctions over traditional auctions. Afterwards, we provide in-depth design requirements that can be taken into consideration while developing such auctions. After that, we analyze technical works that have developed blockchain based energy auctions from green perspective. Finally, we summarize the article by providing challenges and possible future research directions of blockchain based energy auction from green viewpoint.
