In the era of sharing economy, all kinds of new services are based on the social credit data system. From sharing traffic, sharing knowledge to insurance, credit among B2B, B2C and C2C has become more important. Standardized quantitative ratings, credit recovery and credit reporting mechanisms need to be developed and improved. What are the applications of blockchain, big data, cloud computing and other technologies in the field of credit and information management? What projects are waiting there to be fully-developed? What bottlenecks have they encountered? What do governments, investors, business people and professionals think about this? How does impact investing play a role in this process? In this credit and information management Hackathon, the Global Shaper Beijing Hub partners with Credit World, a nonprofit subsidiary of Finance Department of National Development and Reform Commission of China, and strictly selects 4 Chinese social enterprises among many, which implement blockchain, big data, cloud computing technologies in developing social credit areas of finance, transportation, agriculture and social media. Beijing Hub also invites Chinese government officials, top Chinese banking managers, top Chinese VC founders and impact investors to act as professional "hackers" and provide a one-day group mentorship/brainstorm program to help credit-related social enterprises to solve their problems, with structured in-depth group discussions facilitated by Shapers from Beijing Hub and Beijing II Hub.
