A Traceable Smart Grid Trading System under Blockchain

Abstract

In recently years, the traditional bi-directional smart grid system helps users to save energy such as electricity and also could perform the energy trading with other users in the same grid. However, it also requires a trusted third party to help gird users to maintain the transaction to be fair. If there are some users to deny a transaction in the grid, how the trusted third party is able to trace the real identity is the serious problem to be handle currently. As a result, we proposed a traceable smart grid trading system with smart contract in the peer-to peer(p2p) network. We also combine the smart contract into our scheme and adopt the token-based way to make transaction to be fair in case of unexpected problems happened such as the transaction failure.
