In accordance with our bi-annual release schedule and our commitment to transparency, The Elastos Foundation is pleased to share our Financial Report covering January to June 2019.

September 07

Feng Han participated in the China 5G Chain Network Industry Innovation Summit, jointly hosted by Nanjing Chain Network Mobile Technology Research Institute and Babbit. In his speech on, “Data Asset-ization in the 5G Era,” Feng Han expressed that in the future, privatization of data will bring about appraisal and trading of personal data assets, a process that will need a transaction intermediary. Feng believes that the asset-ization of data will change the commercial models of the traditional internet, and will have the following benefits:

1. Individual credit limits will increase across the board;
2. Big-data mining will transform into mining for proof of data rights;
3. Individual digital content creation will transform into tradable digital assets;
4. It will fill the data gap which has caused the disparities in wealth globally.
