李挥教授科研团队发明获2022年度日内瓦国际发明展银奖 The invention of Professor Li Hui’s research team won the Silver Award at the 2022 International Exhibition of Inventions of Geneva

         近日，在2022年第49届日内瓦国际发明展上，来自北京大学深圳研究生院李挥教授团队与佛山赛思禅科技有限公司主导研发的大规模高效能联盟链技术项目“解决联盟链CAP三难困境的专利族及其应用”荣获银奖。
         Recently, at the 49th Geneva International Invention Exhibition in 2022, a large-scale high-performance blockchain technology project led and developed by the team of Professor Li Hui from Peking University Shenzhen Graduate School and Foshan Saisichan Technology Co., Ltd"A patent family solved the CAP trilemma of consensus technology for consortium blockchains" won the silver award.

         据悉，该研究项目是以并行投票证明（PPoV）共识算法为核心的联盟链CAP三难困境（指的是一个分布式系统不可能同时满足一致性、可用性和分区容忍性）解决方案。其中，90%的团队成员为在校研究生。项目首次提出了多层级树形架构，由成百上千条子链组成统一联盟单链，可以支持亿级TPS的吞吐量，完全满足数字货币的零售应用需求。团队也致力于拓宽PPoV与其它领先技术融合的边界，目前已授权相关8项美国发明专利和5项中国发明专利，涵盖未来网络、网络安全、分布式存储等多个领域。
         It is reported that this research project is a solution to the consortium chain CAP trilemma (meaning that a distributed system cannot satisfy consistency, availability and partition tolerance at the same time) with the Parallel Proof of Voting (PPoV) consensus algorithm as the core. Among them, 90% of the team members are graduate students. For the first time, the project proposes a multi-level tree structure, which consists of hundreds or thousands of sub-chains to form a unified alliance single chain, which can support the throughput of 100 million TPS and fully meet the retail application requirements of digital currency. The team is also committed to broadening the boundaries of the integration of PPoV and other leading technologies. At present, it has authorized 8 related US invention patents and 5 Chinese invention patents, covering future networks, network security, distributed storage and other fields.
         此次获奖是李挥教授团队积极推动科技成果转化，拓展技术转移渠道的重要尝试，同时也证明了李挥教授团队卓越的科研实力，得到国际同行的认可和肯定。
         This award is an important attempt by Professor Li Hui's team to actively promote the transformation of scientific and technological achievements and expand technology transfer channels.
