Problems solved by technology

[0004] However, the existing blockchains are independent, and the data inside each blockchain is only for its internal sharing. To achieve data exchange and sharing between different blockchains, manual participation is required, resulting in cross-block The data access efficiency of the chain is low

Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] figure 1 It is a flow chart of Embodiment 1 of the cross-blockchain data access method of the present invention. Such as figure 1 As shown, the cross-blockchain data access method of this embodiment may specifically include the following steps:

[0064] 100. If the registered blockchain device agrees to the registration request of the registered blockchain device, the registered blockchain device detects whether there is newly written block data in the registered blockchain device;

[0065] The data access method across blockchains in this embodiment takes two independent blockchain devices as an example, and implements data access by registering and being registered. That is, by applying for registration from the registered block chain ...

Abstract

The invention provides a cross-data-block data access method, apparatus and system, and a computer readable medium. The method comprises the following steps: if a registered block chain device agreesto a registration request of a registration block chain device, the registered block chain device detects whether there are newly written block data in the registered block chain device; if yes, the registered block chain device obtains a monitoring address and a monitoring port corresponding to a pre-stored registered block chain device; and the registered block chain device pushes a message carrying the newly written block data to the registration block chain device through a secure communication channel formed by the monitoring address and the monitoring port. By adoption of the technical scheme of the invention, the monitoring of the registered block chain device by the registration block chain device and the notification of the registered block chain device on the registration block chain device are achieved through a registration mechanism, and finally cross-data-block data access is achieved. In the cross-data-block data access of the invention, no manual participation is needed, and the access efficiency is high.

Description

【Technical field】 [0001] The present invention relates to the technical field of computer applications, in particular to a cross-blockchain data access method, device, system and computer-readable medium. 【Background technique】 [0002] As blockchain technology is more and more widely recognized and recognized, how to realize data exchange and transmission between blockchains, how to connect independent and isolated blockchains through cross-chain technology to form a larger pan Blockchain networks are becoming more and more practical. [0003] For example, there is an independent supply chain blockchain and an independent commodity sales blockchain, and the combination of the two blockchains can cover the entire life cycle of a commodity from production to sale. If the data of the two blockchain chains are shared and exchanged through cross-chain technology, the traceability of the entire life cycle of a commodity can be realized, as well as data mining based on the realiz...
