Problems solved by technology

Heterogeneous blockchains cause supplier management departments to query sufficient credit information about suppliers, and need to understand the technical architecture and protocol specifications of each supply chain platform blockchain, which makes data access and query management more difficult
[0006] (2) Chains are isolated from each other, and information islands still exist
[0007] Each blockchain of different supply chains operates independently in a closed loop, and there is no information interaction between different chains, so it is difficult to form comprehensive and compl...

Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be apparent from the embodiments of the present invention, which will be described below. Based on the embodiments of the present invention, those of ordinary skill in the art will belong to the scope of the present invention in the scope of the present invention without making creative labor premises.

[0027] See figure 1 The present invention provides a block sharing method based on a block chain based credit data, including:

[0028] S1, establish a multi-chain coordination network between multiple heterogeneous block chain networks, enabling different block chain systems to establish data access connections to each other. Divide nodes in the block chain network, the node is the minimum operating unit that makes up the entire multi-chain architecture, divides the nodes in the zone chain network into normal nodes, interactive nodes, relay according to the functions required for multi-chain operation...

Abstract

The invention provides a credit data cross-chain sharing method and device based on a block chain, and the method comprises the steps: building a multi-chain coordination network between a plurality of heterogeneous block chain networks, and enabling different block chain systems to be capable of building data access connection with each other; combining a Diffie-Hellman key exchange algorithm and utilizing a multi-chain coordination network to realize identity verification to complete credit data transmission. Compared with the prior art, the credit data cross-chain sharing method and device based on the block chain provided by the invention ensure the security of cross-chain interaction and the global consistency in a multi-chain scene, and enhance the security of data cross-chain sharing.

Description

Technical field [0001] The present invention relates to the field of block chains, and more particularly to a block-chain sharing method and apparatus based on a block chain. Background technique [0002] The architecture of the block chain to centralize data is not tampered with, safe and credible traceability, etc. Impact supplier credit data interaction between supply chain systems running on different zone chain networks. Different supply chain systems depends on a variety of heterogeneous block chain platforms, connect the integrated union block chain platform to play the value of the zone chain and supply chain. At present, most of the cross-chain schemes are for asset transfer or inter-chain sharing between payment systems. It is not possible to fully apply to supplier credit data sharing, which is less plan for resolving the supplier credit data across chain sharing. The authentication between the chain nodes and the safety protection methods during the transition data tr...
