Phi is an easy-to-use environment for simulating, finding investment for, and managing clean and decentralized energy systems. In the transition from fossil fuels, we need to create, store, and use electricity in more collaborative ways. With Phi everyone can run collaborative energy projects on the blockchain. With Phi you can simulate P2P energy systems. Add generators and peers to the map, and see what it takes to power the network. Test different ideas before submitting projects for investment. Grow the value of clean and decentralized energy. Phi helps new projects find investment, and communities select simulations to build. Groups can chat about proposals, and vote to allocate shared funds. After investment, projects can be built. Peers collaborate to manage shared infrastructure, reach collective desicions, design smart contracts, and exchange tokens. Tokens keep track of electricity that moves through the network.
