Embodiment 1

[0029] Embodiment 1 of the present invention provides a data sharing method, which is suitable for providing a server end of a blockchain distributed network, such as figure 1 shown, including the following steps:

[0030] Step S101: Obtain multiple smart contracts containing user information. In order to realize data query and sharing based on blockchain and smart contracts, the smart contract constructed in step S101 should at least have storage and query functions. In order to overcome the defect that the shared data lacks logical relationships when using blockchain for data sharing in the prior art, in a specific implementation, when building a smart contract, description information and logical relationships can be written in the smart contract at the same time, In this way, it is avoided to read and analyze the shared data with the help of external business logic after obtaining the query data, and to call the block chain interface again to store the certificate for the...

Embodiment 2

[0036] Embodiment 2 of the present invention provides a data sharing method, which is suitable for providing a server end of a blockchain distributed network, which includes all the steps disclosed in Embodiment 1, and will not be repeated here to avoid repetition. Embodiment 2 of the present invention provides specific steps for step S101 to obtain multiple smart contracts including user information. In Example 2, the constructed smart contracts include behavior contracts, credit evaluation contracts and credit granting contracts. Among them, the behavior contract is used to obtain user information; the credit evaluation contract is used to evaluate user behavior and value based on user information to form a corresponding value evaluation result; the credit contract is used to form a corresponding credit line based on the value evaluation result. Due to the overlapping functions of the above-mentioned smart contracts, in order to simplify the smart contracts, the smart contra...

Embodiment 3

[0055] Embodiment 3 of the present invention provides a server, such as Figure 5 As shown, it includes: a processor 1 and a memory 2 communicated with the processor 1 . The memory 2 stores instructions executable by the processor 1, and the instructions are executed by the processor 1, so that the processor 1 executes the data sharing method as described in any one of the embodiments 1-2.

Abstract

The invention provides a data sharing method and a server. The method comprises the following steps that multiple smart contracts including user information are acquired; the smart contracts are transmitted to a block chain; a data inquiring request is acquired; and the data included in the smart contracts corresponding to the data inquiring request are fed back. According to the data sharing method and the server, the smart contracts are constructed, and the data corresponding to the inquiring request can be directly acquired by performing the smart contracts after the inquiring request transmitted by the user is received so that the step of information selection according to the stipulation in the smart contracts can be avoided and data inquiring or sharing is enabled to be simpler and more convenient. Besides, description information and logic relationship can be simultaneously written in when the smart contracts are constructed so that reading and analyzing of the shared data by means of the external business logic can be avoided, and the requirement for calling the block chain interface for evidence of the analysis result again can be avoided.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a data sharing method and a server. Background technique [0002] In the existing technology, when using the blockchain for data sharing, the general method is: the user sends a digital asset to the blockchain address, and at the same time adds a part of the shared data information. After the addition is completed, it is broadcast to the nodes of the entire network for data sharing. This method of using blockchain for data sharing, due to the limited additional information, only description information and no logical relationship, makes it necessary to read and analyze the shared data with the help of external business logic, and the analysis results need to call the blockchain interface again for storage. There is a lack of continuity; and the shared data information cannot be randomly combined to meet the needs of more application scenarios. [0003] The Chinese inventi...
