    What this paper is doing

    This paper studies how to address the security challenges caused by untrusted and nontransparent energymarkets in Peer-to-Peer(P2P) energy trading.

    What are the major contributions of this paper

    The contributions include:

    1. A consortium blockchain technology to propose asecure energy trading system named energy blockchain.
    2. A credit-based payment scheme to support fast and frequent energy trading.
    3. An optimal pricing strategy using Stackelberg game for credit-based loans.

    To describe the methodology of the proposed approach

    The rationale of the proposed approach is depicted as follows.

    Blockchain Enabled Enegry Trading for IIoT

    The energy blockchain performs the consensus process on pre-selected EAGs with moderate cost. These EAGs collect and managetheir local transaction records. The transaction records arestructured into blocks after finishing the consensus process among the EAGs, and thus stored in the memory pool.

    Creat-based Payment For Fast P2P Enegry Trading

    A credit bank in each authorized EAG works as atrusted bank node with enough energy coins. The credit banks provide energy coin loans for energy nodes according to their credit values, then the energy coins will be transferred from the credit banks’ accounts to the wallet addresses shared between the credit banks and borrowers.

    Optimal Loan Pricing In Credit-based Payment

    Present the problem definition about theamount of energy-coin loan and loan pricing (i.e., interest rateand penalty rate) for borrowers to maximize economic benefitsof credit banks. Energy buyers without enough energy coinsact as borrowers to apply for loans from the credit bank in alocal EAG. After that, the borrowers worked as energy buyerscan buy energy from energy sellers.

    What are the key findings of their study

    Security analysis shows that this energy blockchain achieves secure energy trading, and numerical results illustrate that the energy blockchain and the credit-based payment scheme are effective and efficient for energy trading.
