Constellation, a distributed infrastructure that connects big data with blockchain, has acquired Dor, a startup that helps retail brands grow by providing data analytics solutions. With the acquisition, Constellation will be able to acquire and codify Dor’s voluminous foot traffic data and link it with other large consumer datasets. This data will provide new insight into the spending habits of millions of consumers without compromising privacy. Dor will continue its retail operations while working with Constellation to develop new blockchain-focused products.
