Blockchain technology makes it possible to decisively accelerate the transition toward an environmentally sound, resilient and efficient energy system. With Switzerland’s first «Energy Blockchain Hack», Swisspower and EWF seek to advance the development of practically relevant blockchain solutions in the energy sector. During 48 hours, start-ups and teams of developers will develop prototypes for the application of blockchain technology in the energy sector. The challenges are sponsored by EWF and various energy providers. Hackathon participants can thus expect exciting tasks with direct practical relevance.
