Qtum is a cryptocurrency that allows mobile and IOT devices to execute smart contracts, using a proof of stake consensus. Qtum doesn’t utilize voting, master nodes, or minimum coin requirements. Instead, the number of coins that you hold in your wallet determines how likely you are to create stake blocks and get rewarded.
This technology can be used in many different use cases, from verifying the origin or contents of items like wine or fine art, to creating a mesh network of satellites around the world–anything with sensitive data that can be protected by putting in on the blockchain.
Qtum uses an independent blockchain that is related to Ethereum. In the future, Qtum hopes to release a platform that can act as an app store, for companies to purchase and download smart contracts that they can use for their own business needs.
