WiMi Hologram Cloud Inc., a leading global provider of holographic augmented reality (“AR”) technology, announced that it has built a decentralized file storage and sharing system by implementing the distributed hash table (DHT) technology of the Bitcoin algorithm.
The Bitcoin network is a distributed network consisting of many nodes without a centralized control node. WiMi draws on this decentralized idea of building a file storage and sharing network consisting of multiple nodes. Each node has a certain amount of storage space and is interconnected with other nodes. This distributed storage eliminates dependence on a single data center and improves data security and fault tolerance.

DHT is a basic distributed network algorithm that maps a file’s hash to the address of the node storing the file via a huge file-indexed hash table. The Bitcoin algorithm can be applied to build such a DHT system for decentralized file storage and sharing. The Bitcoin algorithm provides strong technical support for decentralized storage with its decentralization, security and immutability. DHT is a distributed data storage and retrieval mechanism. In the WiMi system, DHT is used to chop files into small chunks and store those chunks spread across multiple nodes. Through the hash function of the DHT, the system can determine the storage location of the file and realize efficient data retrieval. When a user uploads a file, the system cuts it into small pieces and stores them on other eligible nodes; when a user downloads a file, the system extracts the pieces of data from the corresponding nodes and reassembles them into a complete file.

In this system, files are split into small chunks and hashes are calculated using Bitcoin’s hash algorithm. The hash of each file block is used as an index to map it to the address of the node where the file block is stored. This way, when users need to access or share a file, they only need to provide the hash of the file block and the system will be able to look up the address of the node storing the file block from the DHT and transfer the file block to the user.
Decentralized technology improves system reliability and reduces the risk of a single point of failure, as nodes in the network work together to support and manage file storage and sharing. Bitcoin’s hash algorithm and blockchain technology ensure file integrity and tamper proof by verifying the hash of a file block to protect file integrity against tampering and corruption. DHT technology allows file blocks to be distributed among nodes in the network, enabling parallel and distributed file storage and sharing, improving system performance and speeding up file transfers. In addition, Bitcoin’s algorithm enables anonymous file storage and sharing, allowing users to upload and download files using anonymous identities to protect their privacy.
By using the Bitcoin hashing algorithm and blockchain technology, the integrity and anti-forgery of the files are effectively protected. The system checks the hash of the file block to ensure file integrity and prevent tampering and corruption. In addition, DHT technology allows file blocks to be distributed among nodes in the network, thereby realizing parallel and distributed storage and sharing, which greatly improves system performance, as well as speeds up file transmission.
In addition to efficient and secure file storage and sharing, the Bitcoin algorithm provides the system with anonymity. Users can upload and download files using anonymous identities to protect their privacy. This anonymity feature increases users’ confidence in the system and comfort in using it, and further satisfies their need for data security and privacy protection.
