One of the principal applications of blockchain technology is peer-to-peer energy trading among stakeholders of smart grids, providing trusted transactions without the need of third parties. Also, e-auctions are rapidly growing as a mean of e-commerce that allows direct product bidding through the internet. One of the major issues of e-auctions is the reliance on a third-party to host the e-auction platform which not only induces extra cost and complexity of transactions, but also the third-party should be trusted by buyers and sellers, as it handles all the e-auction processes. In addition, trust may also be undermined by potential malicious sellers or buyers. This paper introduces a blockchain-based energy trading framework based on a sealed bid auction type to offer a safe, trusted and privacy preserving energy exchange mechanism between EPES stakeholders of an islanded part of the grid that constitute an energy community, developed in context of the SDN-microSENSE. Furthermore, this framework utilises blockchain solutions for monitoring the security status of smart grid devices in order to confront any transactions involving malicious parties or parties with compromised equipment.
