Embodiment Construction

[0051] Before implementing the method provided by this application, a cross-channel asset exchange model needs to be established, that is, the method of this application is completed based on a specific model, and the established model will be described below.

[0052] see figure 1 , which is a call sequence diagram of a cross-chain transaction method applied to alliance chains to execute cross-chain transactions provided by this application;

[0053] Depend on figure 1It can be seen that the model established in this application is mainly composed of the client (where the user is located), cross-chain middleware, any node (transaction node) located in different chains (A / B), and cross-chain accounts; among them, the cross-chain The middleware is mainly responsible for constructing the cross-chain request according to the user's needs, and calling the cross-chain account to sign the cross-chain request, and sending the signed cross-chain request to both parties of the transac...

Abstract

This application discloses a cross-chain transaction method and system applied to the alliance chain, including the certificate key component to establish a cross-chain account according to the account registration request sent by the client; the cross-chain middleware according to the identity information, cross-chain account and transaction amount Construct a cross-chain request, and call the cross-chain account to sign the cross-chain request; the cross-chain middleware sends the signed cross-chain request to the source node and the target node respectively; the source node and the target node respectively The above cross-chain request is verified to generate a cross-chain transaction certificate; the cross-chain middleware verifies the cross-chain transaction certificate fed back by the source node and the target node, and the verification result is fed back to the client; this application introduces a cross-chain middleware The software is used to complete the message interaction between different chains, the verification of the validity of the transaction, and the transaction verification work. By introducing the certificate key management component, the privacy and authority issues of the owner of the cross-chain transaction are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of data transactions, in particular to a cross-chain transaction method and system applied to alliance chains. Background technique [0002] As a distributed public accounting system, blockchain has many characteristics such as unforgeable data, traceability, tamper-proof and data isolation. At present, the industry's blockchain products (consortium chains) are distributed in many different industries. For a specific blockchain product, the capacity of a single chain is always limited, and the processing capacity of the blockchain is limited. It requires horizontal expansion between chains in some businesses. Therefore, it is necessary to realize the interconnection between different structural chains. However, due to the great differences in mechanisms such as block structure between different structural chains, it is often more complicated to realize cross-chain transactions. [0003] Some of the curren...
