Power grids are undergoing major changes due to rapid growth in renewable energy and improvements in battery technology. Prompted by the increasing complexity of power systems, decentralized IoT solutions are emerging, which arrange local communities into transactive microgrids. However, providing security, safety, and privacy in such energy systems is challenging. We introduce PETra, a blockchain-based solution for transactive microgrids that enables consumers to trade energy without sacrificing their privacy and provides safety and security for the grid.
