Block chain-based data sharing platform and implementation method thereof

Abstract

The invention provides a block chain-based data sharing platform and an implementation method thereof. The platform comprises multiple clients, one or more access servers and a block chain system; theclients are used for submitting registration applications, storing data instructions, querying the data instructions and using the data instructions; the access servers are used for receiving operation requests submitted by the clients, verifying identities of the clients and the operation requests, submitting the data operation requests to the block chain system and feeding results to the clients; and the block chain system is used for controlling storage and access of data, storing the data and storing citation and abstract information on the data, and access permissions are controlled by block chains and used as tamper-proof logs. According to the block chain-based data sharing platform and the implementation method thereof, the ownership and the right to use of the data are separated,a traceable path is provided for the ownership and usage of the data for audit, queries and transactions are asynchronously executed, and the data sharing efficiency and reliability are improved.

Description

technical field [0001] The invention belongs to the field of computer technology, relates to block chain technology, and is a block chain-based data sharing platform and an implementation method thereof. Background technique [0002] In the information society, data, as a new means of production, has become the consensus of everyone. The traditional nature of data sharing is irreversible, once data is sent, it cannot be taken back and limits its use. Therefore, the traditional data transaction process often leads to many legal disputes, such as: illegal reselling of data, disputes over data ownership, and so on. These problems are all due to the opacity of data transaction information, and even the existence of false information, which has caused great difficulties in proving evidence and pursuing accountability. The distributed network of the blockchain enables the account books of each complete node to be propagated to other nodes through the distributed network, and the...

These problems are all due to the opacity of data transaction information, and even false information, which has caused great difficulties for proof and accountability

The distributed network of the blockchain enables the account books of each complete node to be propagated to other nodes through the distributed network, and the nodes verify the authenticity of the account books through the consensus mechanism, which ensures the decentralization, permanence, and non-tamperable characteristics of the blockchain. However, the distributed nature of the original blockchain makes the amount of data storage limited, and data storage generally relies on transaction records.
