The Research on Blockchain Hybrid Consensus Mechanism (hereafter referred as the Research) was jointly established by the Key Laboratory of Internet Big-data Security Analysis of Harbin Institute of Technology (hereafter referred as the Lab) and THEKEY, aiming at exploring the PoP (Proof of Power) hybrid consensus mechanism, which is fundamental for the IDV productive deployment, optimizing the blockchain application in social insurance and facilitating the social security data socialization.

Harbin Institute of Technology is the national key university and directly subordinate to Ministry of Industry and Information Technology of the People’s Republic of China (MIIT). The Lab was selected as one of the 27 national key laboratories by MIIT in 2018, and plays important role in the national big-data technology research and development. The cooperation of THEKEY and the Lab focuses on the hybrid consensus mechanism development, where the Lab will work out the solutions theoretically and technically, and THEKEY will verify them through various application scenarios.

On June 1st, the seminar was held in Nanjing Financial Technology Research and Innovation Center.

However, safety is still the great challenge that the social security data socialization facing. Blockchain technology provides a perfect solution to the quandary, which will fundamentally improve the user experience of China social security, lower the service cost, and facilitate the social security data socialization under the premise of data security. On the other hand, China social security also provides the most complicated and practical application scenarios for blockchain research and development.
