[{"type":"text","content":"BEIJING, July 18, 2023 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ: WIMI) (\"WiMi\" or the \"Company\"), a leading global Hologram Augmented Reality (\"AR\") Technology provider, today announced that it had developed an IIoT data storage system based on Local Reconstruction Codes (LRC) sharding blockchain. It combines distributed storage technology with blockchain to achieve efficient, secure and reliable IIoT data storage and management.\nThe overall structure of the system is as follows:\nGlobal networkA global/centralized network can provide the highest resource capacity. It follows the traditional centralized cloud computing approach and consists of cloud server hosting software. It is responsible for planning, monitoring, and managing resources and handles the logical execution of the functional components of the architecture, providing a globally available service platform for applications requiring high storage and computational capacity. As the core architecture of the IIoT, it is connected to the blockchain to form the overall system architecture.\nEdge networkBlockchains are connected through a global network as an edge network. Each blockchain contains N slice(s). Each slice includes an edge node and an IIoT node that can be stored in the licensed blockchain. Two nodes are connected to form a slice node. Finally, the edge network is connected to the global network to form the overall structure. To further improve the system structure formed by the IIoT and the slice blockchain, WiMi adds LRC to solve the IIoT data reliability problem and a bilinear accumulator to solve the blockchain's data storage and verification security problem. The structure achieves data storage security through a bilinear accumulator and adopts coded sharding technology to ensure data reliability and blockchain scalability during operation. In the system structure, the coded sharding technology ensures the data reliability of IIoT and increases the fault tolerance of the blockchain system. At the same time, the encoding of data can improve the attack resistance of the system.\nLRC sharding blockchainTo better secure the data in IIoT, this data storage system encodes the data blocks in each slice node of the blockchain. This slice coding is used to ensure the reliability of data. LRC provides data reliability in the blockchain and has lower...
