Gridsum and MMA China Launch a Distributed Invalid Traffic Filter System

BEIJING,Aug. 28,2018 --Gridsum Holding Inc.("Gridsum" or the "Company") (NASDAQ: GSUM),a leading provider of cloud-based big-data analytics and artificial intelligence ("AI") solutions inChina,today announced that it has cooperated with the Mobile Marketing Association China ("MMA China") on a General Invalid Traffic ("GIVT") List program to launch a Distributed Invalid Traffic Filter System (the "DIF System").

Invalid traffic is a substantial problem for marketers. The cutting edge of GIVT consists of traffic identified through routine means of filtration executed through application of machine intelligence,lists and other standardized parameter checks. In practice,GIVT traffic is identified via pattern recognition leveraging available lists of IP addresses,IMEI numbers,browser identifiers and other signatures,or from activity clearly matching non-human patterns of behavior,such as a click frequency.

Gridsum was the major contributor in adopting blockchain technology into the DIF System,with RTBAsia,the leader of the GIVT List working group leading the research and development of the DIF System. Blockchain technology features smart contracts and consensus mechanisms,allowing the DIF System to merge and filter-out invalid advertising traffic in real time.

Mr. Guosheng Qi,Chief Executive Officer of Gridsum,commented,"Gridsum was among the first members to join the GIVT List working group and the DIF Consortium Blockchain. With the use of blockchain technology,we believe that the DIF System can significantly enhance the responsiveness and traceability of the GIVT List. We remain committed to working with MMA China to solve the industry's key bottlenecks and hope that more companies join us in building a vigorous digital marketing ecosystem in China."
