BEIJING, July 5, 2023 /PRNewswire/ — WiMi Hologram Cloud Inc. (NASDAQ: WIMI) (“WiMi” or the “Company”), a leading global provider of Hologram Augmented Reality (“AR”) technology, today announced that it has developed a distributed image storage protocol (DISP), which effectively the blockchain saves storage space and reduces computing costs using the Inter Planetary File System (IPFS).
The distributed pool blockchain protocol can divide the stored data into multiple small blocks and distribute these small blocks on different nodes to achieve distributed storage and backup. The protocol can also use blockchain technology to ensure the security and reliability of the data, making the stored image data less susceptible to manipulation or loss. However, since image data is usually large, splitting it into multiple small blocks to be stored on the blockchain can lead to inefficient storage and transmission.
WiMi proposes a blockchain distributed storage protocol based on a pooling algorithm and a reverse process. WiMi combines the IPFS protocol to store extensive image data and uses the distributed pool blockchain protocol to manage and verify the blocks of data stored in IPFS. The IPFS protocol can break image data into small blocks and store it on different nodes in the network using a distributed approach for efficient storage and transmission. And the distributed pool blockchain protocol can ensure the data integrity and reliability through hashing and blockchain storage of the data blocks stored in IPFS.
WiMi’s DISP protocol is designed to be optional and non-mandatory, and users who do not accept the DISP protocol can still use the traditional fully redundant storage approach. Users who accept the protocol can enjoy the benefits of space savings without compromising security performance. The DISP protocol turns fully redundant storage relative to individuals into full community-level redundancy, where data stored in each community node is not redundant. In DISP, distributed storage improves data protection performance by ensuring that not all data is lost in the event of an attack or single node failure. The distributed pooling algorithm reduces data redundancy in distributed storage and significantly saves storage space.
In the pre-processing stage, before implementing the distributed pooling algorithm, WiMi’s DISP protocol divides the original image into several pooling regions based on the shape of the pooling kernel, forming a series of pooling regions to be processed. The image can then be divided into several parts and stored in multiple nodes by the distributed pooling algorithm.
The addresses that accept the protocol are collected to form different communities, and the number of nodes in each community is determined by the number of merged images obtained after the decomposition algorithm. At a given compression ratio, each piece of data is still identifiable and can be recovered losslessly through compressed detection or super-resolution display. When all data fragments are collected in the community, the algorithmic inverse operation can recover the original data without loss. Each node stores data that differs from the data of other nodes in the community, which would otherwise be classified as a different community. Every node in the community can see the full picture of the data. If the corresponding data fragments stored by each node in the community are collected together, the source data can be recovered without loss after calling the proof phase.
The implementation of WiMi’s DISP protocol is as follows:
Image blocks: The image data to be saved is divided into multiple blocks, and the size of each piece can be adjusted as needed.
IPFS Storage: The segmented image data is stored in the IPFS network, and the IPFS protocol is used to realize distributed storage and backup.
Blockchain Validation: Blockchain technology is used to manage and validate the blocks of data stored in IPFS, ensuring the integrity and reliability of the data. Specifically, each data block has a hash value that can be stored on the blockchain, which is used to record the data block’s change history.
Accessibility Control: Smart contracts are used to achieve accessibility control of image data, such as restricting the access of specific users or applications to certain image data.
WiMi’s DISP protocol enables efficient, secure, and reliable image storage. Compared to traditional blockchain storage methods, the protocol stores image data in multiple small blocks in IPFS, effectively reducing storage space. At the same time, the integrity and reliability of the data blocks are verified using blockchain technology, making the stored image data less susceptible to manipulation or loss. A hybrid solution enables more efficient, secure and reliable image storage to leverage the benefits of each resulting in better performance and results.
