New information and communication technologies (ICT) are creating whole new industries and opportunities. This will have structural implications also for energy utilities, DSOs, energy communities (EC) and prosumers. The decentralized finance industry is using new technologies and token economics (TE) that create novel financial applications and business models that can have a significant impact on how the energy transition can be financed. The concept of fractional ownership has been identified as a new possibility to create innovative business models [1]. Utilising tokenisation and DeFi concepts, we could be able to develop flexible, scalable and replicable financing instruments.

The Challenge

Implement the concept of fractional ownership, tokenisation of energy and utilisation of open-source blockchain and DeFi protocols. Build a MVP for fractionalising digital asset (ownership), lending, borrowing and auctioning of those ownership fractions that allows PV systems owners to (re)finance existing or new projects, and trading ownership rights of their projects.


You do not have to be a full stack developer. Basic knowledge of solidity, javascript or how to build DApp using the react framework next.js and IPFS would be very helpful. Also, if you are new in blockchain you are very welcome to join the project. During the hackathon I will provide information about the architecture, existing code solutions and tools.
