Peking University Assigned Patent

Peking University, Beijing, China, has been assigned a patent (11,157,487) developed by Huang, Gang, Liu, Xuanzhe, Zhang, Ying, Ma, Yun, Jing, Xiang, and Wu, Yi, Beijing, China, for “trusted storage method and system based on directed acyclic graph structure.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A trusted storage method and system based on a graph structure are provided. The method includes: in a process of initiating a transaction, randomly selecting, by each transaction initiating node, a plurality of witness nodes from a network for witnessing the transaction, packaging, by the witness nodes, transaction data generated by witnessing the transaction to generate blocks, randomly selecting, by the witness nodes, a plurality of storage nodes, sending, by the witness nodes, the blocks to the plurality of storage nodes, and storing, by the storage nodes, the blocks, wherein, for one transaction, all the blocks of all the witness nodes and all the storage nodes form a directed acyclic graph DAG structure. According to embodiments of the disclosure, the directed acyclic graph DAG structure is employed to be matched with an nRW consensus mechanism, so that a supervision problem in a large-scale sharing and exchanging process is solved.”

The patent application was filed on October 28, 2020 (17/082,549).
