Polarchain's goal is to make use of blockchain technology to make a more efficient, stable, scientific and reasonable edge computing platform. Follow the `principle of everyone is equal` in the blockchain, and realize the proof of contribution effective resources, that is, proof of of use work (pouw). Polarchain collects idle resources such as broadband, computing, storage and so on, so that everyone can become an edge computing node, and each edge node can process, execute nearby services and obtain revenue. We rely on numerous nodes to form a decentralized peer-to-peer edge computing platform, which eventually becomes the super edge cloud - polarchain.
