Chia is an open source decentralized peer-to-peer smart transaction platform that aims to improve the efficiency of blockchain technology. The project uses an original consensus mechanism known as proof-of-space-and-time (PoST) and a unique programming language called Chialisp to reduce electricity consumption by the network. XCH is the native token of the Chia protocol used to build dApps on the network and incentivize participants for helping to secure the network.
