In recent years, with the rapid development of blockchain technology applications, more and more application scenarios have begun to use distributed ledgers to store and verify data. In terms of image storage, traditional centralized storage methods may have some security and reliability issues, so the distributed pool blockchain protocol can be an effective solution. WIMI (NASDAQ: WIMI) has developed a Distributed Image Storage Protocol (DISP) for image storage, and uses the Interplanetary File System (IPFS) to effectively improve blockchain storage space and reduce computing costs.

The distributed pool blockchain protocol can divide the stored data into multiple small blocks and distribute these small blocks on different nodes to realize distributed storage and backup. At the same time, the protocol can also use blockchain technology to ensure data security and credibility, making the stored image data difficult to be tampered with or lost. However, since image data is usually relatively large, storing it in multiple small blocks on the blockchain may result in inefficient storage and transmission.

WIMI proposes a blockchain distributed storage protocol based on the pooling algorithm and its inverse process, combined with the IPFS (InterPlanetary File System) protocol to store large image data, and uses the distributed pool blockchain protocol to manage and Validate blocks of data stored in IPFS. The IPFS protocol can divide image data into multiple small blocks and store them on different nodes in the network in a distributed manner to achieve efficient storage and transmission. The distributed pool blockchain protocol can ensure the integrity and credibility of the data by performing hash operations and blockchain storage on the data blocks stored in IPFS.

The WIMI Holographic DISP protocol is designed to be optional and non-mandatory. Users who do not accept the DISP protocol can still use the traditional full redundant storage method. Users who accept the agreement can enjoy the benefits of saving space without compromising security performance. The DISP protocol changes the fully redundant storage relative to individuals to community-level full redundancy, that is, the data stored in each node of a community has no redundancy. In DISP, distributed storage ensures that all data will not be lost when a small number of nodes are attacked or fails, thereby enhancing the performance of data security. The distributed pool algorithm reduces the data redundancy of distributed storage and greatly saves storage space.


WIMI (NASDAQ: WIMI) DISP protocol, in the preprocessing stage before implementing the distributed pooling algorithm, first divides the original image into several pooling areas according to the shape of the pooling kernel to form a group of pools to be processed area. The image can then be divided into several parts by a distributed pooling algorithm and stored in multiple nodes.

Addresses that accept the protocol will be collected to form different communities, and the number of nodes in each community is determined by the number of pooled images obtained after the decomposition algorithm. Under a certain compression ratio, each piece of data is still identifiable and can be represented losslessly by compressed sensing or super-resolution. If all the data fragments in the community are collected, the original data can be restored losslessly through the algorithmic reverse operation. The data saved by each node is different from the data of other nodes in the community, otherwise, the node will be divided into another community. Every node in the community can see the whole 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 the evidence phase is invoked.

The implementation steps of WIMI holographic DISP protocol are as follows:
Image segmentation:
Divide the image data to be stored into multiple small blocks, and the size of each small block can be adjusted as needed.

IPFS storage:
Store the divided image data in the IPFS network, and use the IPFS protocol to realize distributed storage and backup.

Blockchain verification:
Use blockchain technology to manage and verify data blocks stored in IPFS, thereby ensuring data integrity and credibility. Specifically, each data block has a hash value, which can be stored on the blockchain, and the blockchain is used to record the modification history of the data block.

Accessibility control:
Use smart contracts to implement accessibility control over image data, such as restricting certain users or applications from accessing certain image data.

WIMI (NASDAQ: WIMI) DISP protocol can realize efficient, safe and reliable image storage. Compared with the traditional blockchain storage method, this protocol divides the image data into multiple small blocks and stores them in IPFS, thus effectively reducing the storage space occupied by the blockchain. At the same time, blockchain technology is used to verify the integrity and credibility of data blocks, so that the stored image data is not easy to be tampered with or lost. More efficient, safer, and more reliable image storage can be achieved using a hybrid scheme. In order to make full use of their respective advantages, so as to achieve better performance and effect.
