Embodiment 1

[0030] A kind of distributed storage method, it is characterized in that, the file that will be stored is represented by hash value, distributes by BitTorrent agreement, specifically comprises:

[0031] S1. Build a blockchain network based on the Interplanetary File System (IPFS) protocol;

[0032] S2. Build a private chain different from the blockchain network;

[0033] S3. The uploader in the distributed storage network generates an upload request, and records the upload request in the contract of the private chain;

[0034] S4. Divide the file to be stored into multiple files and upload them to the blockchain network based on a specific protocol;

[0035] S5. The depositor in the distributed storage network generates a storage request, and records the storage request in the contract;

[0036] S6. The DHT (distributed hash table) on each node of the block chain network synchronously stores the upload request and the storage request of the file;

[0037] S7. Store the file...

Embodiment 2

[0048] A kind of distributed storage method, it is characterized in that, the file that will be stored is represented by hash value, distributes by BitTorrent agreement, specifically comprises:

[0050] S2. Build a private chain different from the blockchain network;

[0051] S3. The uploader in the distributed storage network generates an upload request, and records the upload request in the contract of the private chain;

[0052] S4. Divide the file to be stored into multiple files and upload them to the blockchain network based on a specific protocol;

[0053] S5. The depositor in the distributed storage network generates a storage request, and records the storage request in the contract;

[0054] S6. The DHT (distributed hash table) on each node of the block chain network synchronously stores the upload request and the storage request of the file;

[0055] S7. Store the file...

Embodiment 3

[0066] For a better understanding of this application, refer to figure 2 A block diagram of a distributed storage system is shown. Based on the system block diagram, this embodiment provides a distributed storage method, which is characterized in that the stored file is represented by a hash value, and the file is stored through the BitTorrent protocol. distribution, including:

[0067] S1. Build a blockchain network based on the Interplanetary File System (IPFS) protocol;

[0068] S2. Build a private chain different from the blockchain network;

[0069] S3. The uploader in the distributed storage network generates an upload request, and records the upload request in the contract of the private chain;

[0070] S4. Divide the file to be stored into multiple files and upload them to the blockchain network based on a specific protocol;

[0071] S5. The depositor in the distributed storage network generates a storage request, and records the storage request in the contract;

Abstract

The invention discloses a distributed storage system, which realizes distribution autonomy of storage nodes in the distributed storage system and consensus algorithm-based data exchange and data sharing among storage nodes by utilizing the characteristics of decentralization and trust removal in the construction process of the distributed storage system. Compared with a current mainstream centralized cloud service system, network nodes can establish many-to-many rather than one-to-many contact relationships, and the data transmission efficiency can be greatly improved; in the data storage, exchange, uploading and downloading processes, data block packaging, anonymous exchange and asymmetric encryption algorithms are adopted respectively, so that the safety and reliability of the whole ecological chain of data cloud storage are greatly ensured. Compared with a mainstream centralized cloud service system at present, the system operation efficiency can be greatly improved on the basis of improving the data security, and the operation cost of the cloud storage service is reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for distributed storage of data. Background technique [0002] Blockchain technology has attracted more and more attention with the increasing popularity of digital cryptocurrencies such as Bitcoin. Blockchain technology is a new type of decentralized protocol that can safely store digital assets such as digital currency and equity claims. By using data encryption, time stamp, distributed consensus and economic incentives, blockchain technology effectively solves the consensus problem in the Byzantine general problem, and realizes decentralized point-to-point in a distributed system where nodes do not need to trust each other. transactions, thus effectively reducing the trust cost of the real economy and redefining the property rights system in the Internet era. [0003] Although the blockchain technology has significantly improved the security and...
