    A Block-Free Distributed Ledger for P2P Energy Trading

    Case with IOTA?

    Across the world, the organisation and operation of the electricity markets is quickly changing, moving towards decentralised, distributed, renewables-based generation with real-time data exchange-based solutions. In order to support this change, blockchain-based distributed ledgers have been proposed for implementation of peer-to-peer energy trading platform. However, blockchain solutions suffer from scalability problems as well as from delays in transaction confirmation. This paper explores the feasibility of using IOTA’s DAG-based block-free distributed ledger for implementation of energy trading platforms. Our agent-based simulation research demonstrates that an IOTA-like DAG-based solution could overcome the constraints that blockchains face in the energy mar- ket. However, to be usable for peer-to-peer energy trading, even DAG- based platforms need to consider specificities of energy trading markets (such as structured trading periods and assured confirmation of transactions for every completed period).
