DataChain is a decentralized big data value economy ecosystem based on blockchain technology. Serving as the unit of exchange between users, data buyers, and data suppliers, it quantifies the value of data. DTCMs next step is to prepare for the development of the next-generation mainchain, providing more efficient consumption solutions for data buyers. We are dedicated to changing the status quo where ordinary users are at the bottom of the value chain, creating a fairer and more transparent environment for data transactions.
