DHX is a cryptocurrency IoT token. DHX is currently available for purchase, sale and mining on several crypto exchanges around the world.
DHX stands for DataHighway, which is a project whose full deployment and use as a parachain is currently under development.
DataHighway's members and supporters will ultimately be incentivised to operate a sophisticated IoT parachain based on Polkadot, where they may stake, govern, mine and otherwise participate using the new DHX token and its associated Decentralized Autonomous Organization (DAO) and Inter-Chain Data Market.
