Here's an article from February 26, 2017 from Harvard Digital Innovation and Transformation Course about GXB.
Gongxinbao (GXB), a start-up in China, provides a trustworthy and consumer-centric marketplace for data exchange by building a blockchain-based decentralized platform. Will this adoption of new technology allow GXB defeat other incumbents in the platform market? Can GXBs business model solve issues that currently hinder the growth of data exchange market?
Thanks for share this information, and as I known the MIT Blockchain Lab is just researching and same as GXB, but it is a little different path.
