According to The Paper, the “Peking University Shurui Distributed Ledger System” developed by Professor Huang Gang from the system software team of the Software Research Institute of Peking University has passed the official test organized by the China Institute of Information and Communications Technology. This is the first domestic distributed ledger system performance test that has passed under the Internet large-scale node production environment. “Beida Shurui” is a ubiquitous interoperability platform developed by the system software team of Peking University for the integration of human-machine-object computing scenarios. It supports on-demand interoperability and trusted control of ubiquitous device data resources such as cloud, network, edge, and end. Distributed ledger is one of Peking University’s infrastructure services. Its core technical feature is to run a parallel consensus protocol by randomly selecting a fixed number of nodes to form a directed acyclic graph (DAG) non-chain data structure to achieve high data The underlying technical architecture with controllable throughput, storage overhead, and high scalability of the system provides high-performance basic technical support for application scenarios such as data management and control. The test results show that the storage performance of the Peking University Suriname distributed ledger system in a public network environment and a scale of 100 nodes can exceed 160,000 TPS. Annotated by the chain, public information shows that Huang Gang has been engaged in teaching and scientific research in the field of system software for a long time. He is currently a professor, doctoral supervisor of the School of Information Science and Technology of Peking University, and an executive member of the IEEE Business Informatization and System Technology Committee.
