Problems solved by technology

[0003] However, different types of data have different requirements for security levels, which limits the sharing of data. For example, data that generally requires high security levels are not shared externally to avoid data leakage
In this case, even if there are abundant data resources, it is difficult to make full use of the data resources, resulting in a serious waste of data resources

Embodiment 1

[0023] see figure 1 , figure 1 This is a flowchart of the blockchain-based data sharing method provided by the embodiment of the present application.

[0024] The present application provides a method for data sharing based on blockchain, including the following steps:

[0025] Step S110, receiving the data to be stored, and calculating the importance of the data to be stored;

[0026] The blockchain is a chain composed of one block unit after another, each block unit stores a certain amount of data, and the block units are connected into a chain according to the time sequence of their generation. The blockchain receives the data to be stored, organizes a certain number of nodes according to the data to be stored to construct block units, for example: organizes a certain number of nodes according to the importance of the data to be stored, and then records the previous node in the block header of each node (specifically, it can be the hash value of the previous node, and it...

Embodiment 2

[0043] see figure 2 , figure 2 It is a schematic diagram of the blockchain-based data sharing system provided by the embodiment of the present application.

[0044] The present application also provides a blockchain-based data sharing system 200 , including: a receiving unit 210 , a computing unit 220 , a writing unit 230 , a consensus unit 240 , a processing unit 250 , a loss computing unit 260 and a sending unit 270 .

[0045] The receiving unit 210 receives the data to be stored, and the calculating unit 220 calculates the importance of the data to be stored.

[0046] The blockchain is a chain composed of one block unit after another, each block unit stores a certain amount of data, and the block units are connected into a chain according to the time sequence of their generation. The blockchain receives the data to be stored, organizes a certain number of nodes according to the data to be stored to construct block units, for example: organizes a certain number of nodes ...

Abstract

The invention relates to the technical field of block chains, in particular to a data sharing method and system based on a block chain, and the method comprises the steps: receiving to-be-stored data, and calculating the importance of the to-be-stored data; writing to-be-stored data into a common node of the block unit, writing a consensus mechanism into a representative node of the block unit, and writing a data processing model into the representative node of the block unit according to the importance degree of the to-be-stored data; in response to the received reading requests of other block units, consensus is carried out on data recorded in the common nodes of the block units through a consensus mechanism in representative nodes; after the consensus is reached, processing the data recorded in the common node through the data processing model in the representative node of the block unit; and performing information loss rate calculation on the processed data, and sending the processed data to other block units according to the information loss rate as a response to the reading request. Data resources can be fully utilized, and waste of the data resources is avoided.

Description

technical field [0001] The present application relates to the field of blockchain technology, and in particular, to a method and system for data sharing based on blockchain. Background technique [0002] With the development of computer, communication and network technologies, as well as the huge and far-reaching impact of globalization and internationalization on the world, the informatization and digitization process of the entire society has been greatly accelerated. Explosive growth, and the huge number also provides a wealth of data resources for the society. [0003] However, different types of data have different requirements for the security level, which limits the sharing of data. For example, data that generally requires higher security levels are not shared to avoid data leakage. In this case, even if there are abundant data resources, it is difficult to make full use of data resources, resulting in a serious waste of data resources. [0004] Therefore, how to m...
