According to reports, WIMI (NASDAQ: WIMI) developed an industrial Internet of Things (IIoT) data storage system based on LRC (Local Reconstruction Codes) sharding blockchain. The IIoT data reliability problem is solved through LRC, and the data storage and verification security problem of the blockchain itself is solved through a bilinear accumulator. It also adopts coded sharding technology to ensure data reliability and blockchain scalability during operation. Efficient, reliable and secure data storage and management.

The Industrial Internet of Things (IIoT) is the continuous integration of various acquisition and control sensors or controllers with sensing and monitoring functions, as well as mobile communication, intelligent analysis and other technologies into all aspects of the industrial production process, thereby significantly improving manufacturing efficiency. Improve product quality, reduce product cost and resource consumption, and finally realize the upgrading of traditional industries to intelligence. However, IIoT is currently an emerging system structure with a complex structure and no unified standard, but security issues in all aspects of industrial control also need to be resolved urgently.

And with the rapid development of Industrial Internet of Things in recent years and the continuous improvement of Industrial Internet of Things technology, more and more enterprises have begun to pay attention to the collection, storage and processing of industrial data. However, the storage and processing of industrial Internet of Things data is facing many technical problems, such as large data capacity, high real-time requirements, data security and reliability and other issues. Among them, the data security of IIoT is facing huge challenges. Blockchain has the characteristics of decentralization and tamper-proof modification, and has natural advantages in solving data security problems of IIoT. WIMI Hologram is based on the LRC sharding blockchain industrial IoT data storage system, and based on distributed storage technology and blockchain technology, it realizes efficient, safe and reliable industrial IoT data storage and management. The overall structure of the system is shown in the figure:

Global network
A global/centralized network can provide the highest resource capacity. It follows the traditional centralized cloud computing method and consists of cloud servers hosting software, responsible for planning, monitoring and managing resources, and handling the logical execution of architectural functional components, providing a globally available service platform for applications requiring high storage and computing capabilities . As the core architecture of IIoT, it is connected with the blockchain to form an overall system structure combining IIoT and blockchain.

Edge network
Blockchains are connected through a global network as an edge network. Each blockchain contains N shards, each shard contains an edge node and an IIoT node that can be stored in the permissioned blockchain, and the two nodes are connected to form a shard node. Finally, the edge network is connected with the global network to form an overall structure. In order to further improve the system structure formed by IIoT and fragmented blockchain, WIMI has added LRC to solve IIoT data reliability issues, and added a bilinear accumulator to solve the data storage and verification security issues of the blockchain itself. The structure achieves data storage security through bilinear accumulators, and uses coded sharding technology to ensure data reliability and blockchain scalability during operation. In terms of system structure, the encoding fragmentation technology ensures the data reliability of IIoT and increases the fault tolerance of the blockchain system. At the same time, the anti-attack ability of the system can be improved by encoding the data.

LRC Fragmented Blockchain Structure
In order to better ensure the data security of IIoT, the data block in each sharding node of the blockchain is encoded based on the LRC sharding blockchain industrial IoT data storage system. This fragmentation encoding is used to ensure the reliability of the data. LRC can not only guarantee the reliability of data in the blockchain, lower bandwidth requirements, higher repair efficiency, but also repair wrong node data.

WIMI (NASDAQ: WIMI) is based on the LRC sharding blockchain industrial IoT data storage system. LRC (Local Reconstruction Codes) is used to provide high reliability and fault tolerance in the distributed storage system. It can repair the stored data locally without restoring data from other nodes or backups.

In the distributed storage system of WIMI, LRC divides the data into multiple data blocks and generates multiple check blocks. The characteristic of LRC is that it will determine a coefficient matrix according to the quantitative relationship between the check block and the data block, and then apply this coefficient matrix to the data block and the check block to generate the check value. When a data block is damaged or lost, by using the check block and check value stored locally, the data block can be repaired locally without restoring data from other nodes or backups.

The advantage of LRC is that it can reduce the overhead of data reconstruction and data transmission, and improve the efficiency of data recovery. At the same time, because LRC can be repaired locally, it can reduce data transmission between nodes, reduce the pressure on network bandwidth, and improve the fault tolerance of the entire system.

With the rapid development and application of industrial IoT technology, WIMI (NASDAQ: WIMI) based on LRC sharding blockchain industrial IoT data storage system has broad market prospects and application requirements, such as:

Industrial production process monitoring
The industrial production process involves data interaction between many devices and systems, and these data usually contain key information of the production process. The industrial Internet of Things data storage technology based on the LRC sharding blockchain can realize real-time collection, storage and management of production process data, ensure data integrity and traceability, and improve the reliability and efficiency of the production process.

Internet of Things device security supervision
Data security supervision of IoT devices is very important for the normal operation of devices and the protection of business secrets of enterprises. The industrial IoT data storage technology based on the LRC sharding blockchain can realize real-time supervision and recording of device data, ensure data security and integrity, and thus ensure the safe operation of IoT devices.

Energy Management and Monitoring
Energy management and monitoring involves real-time monitoring and data collection of energy equipment and systems. Using the industrial Internet of Things data storage technology based on LRC sharding blockchain, real-time monitoring and data collection of energy equipment can be realized, and these data can be safely stored and managed. In this way, we can better understand the energy usage, optimize the efficiency of energy usage, and reduce the energy cost of the enterprise.

Logistics and Supply Chain Management
Logistics and supply chain management involve the transfer and processing of many data, including logistics, goods, orders and other information. The industrial Internet of Things data storage technology based on the LRC sharding blockchain can realize real-time collection and storage of these data, and ensure the security and non-tampering of the data, thereby improving the transparency and traceability of the supply chain and reducing information circulation. risks and uncertainties.
