D3A energy exchange for a transactive grid

Abstract In June 2019, the Energy Web Foundation launched the first public, open source, energy enterprise blockchain, owned and managed by the community. Several energy corporates and startups have deployed commercial blockchain-based applications on the Energy Web Chain, while many others are testing and developing additional decentralized applications or dApps. This chapter explores the role of blockchain, or more precisely smart contracts, in creating a future transactive grid, focusing in particular on the potential early deployment of the D3A, an open source, customizable energy exchange, currently available as a simulation environment.
