Public blockchains are a powerful technology that will revolutionize many industries. The EWF wants to leverage the advantages of public blockchains like ethereum in the heavily regulated energy sector. To enable the safe and efficient use of blockchain technology to run critical infrastructure like electricity grids (e.g. through delivering ancillary services like grid balancing) the EWF introduces special features that will allow a compromise between staying as open and decentralized as possible while at the same being able to give certain guarantees to be compliant with regulation. To enable use-cases that require the integration of physical infrastructure with the blockchain, the EWF and its technology partners parity, slock.it and Grid Singularity develop hardware and software frameworks that facilitate the development of such technologies in the energy sector.
