DCP Quantity is a decentralized big data value economic ecology based on blockchain technology. As a communication unit between users, data buyers, and data suppliers, we quantify the value of data. The DCP platform rewards users who contribute anonymous big data and provides data buyers with more efficient consumption solutions. It is committed to changing the status quo of ordinary users at the bottom of the biological chain and creating a more fair and transparent data trading environment. The encrypted token used to support the DCP ecosystem is Quantity Coin, also known as DCP, developed by DataChainPro issued. DataChainPro is mainly responsible for the issuance, development and promotion of the DCP quantitative ecosystem.
