Privacy-Preserving Exchange Mechanism and its Application to Energy Market

Considering the context of energy market, we propose a blockchain-based privacy-preserving protocol supporting very general kinds of auctions, keeping private not only the bids and participant identities but also auction result, all in a completely verifiable way. We use our scheme described through four algorithms, to instantiate multi-units double auctions which are used in our application to protect privacy in microgrids. A prototype is implemented and performances are presented.
