Embodiment 1

[0095] Such as Figure 5 As shown, the user can view his own stable tokens on chain A, and can select several stable tokens that he can use and transfer them to other accounts. After selecting the Unspent token in the wallet, the user specifies the transaction fee and transfer address, and initiates the transaction. After the cross-chain transactions are synchronized on each chain, you can view the changes in your wallet on other chains. In practical applications, without the present invention, users cannot use the assets of chain A on chain B, and must use off-chain centralized methods, such as centralized exchanges, which have low security and are relatively complicated. Based on the cross-chain Bridge formed by the present invention, the user can convert the assets on the A chain into a cross-chain stable pass through the application of the A chain, and wait for the state of the pass to be synchronized before using the pass in the application on the B chain Purchase B-cha...

Embodiment 2

[0097] Such as Figure 6 As shown, chain A is a blockchain that issues coupons, and a decentralized application for a musical ticket is deployed on chain A, and users can use coupons and stable tokens to purchase the tickets on chain B. After the transaction is successful, you can view the purchased ticket information and the unique ID on the A chain, and the cross-chain transaction is stored on both the A chain and the B chain.

Abstract

The invention belongs to the technical field of block chains, and particularly relates to a data consistency maintenance method for realizing cross-chain interoperation. Aiming at a cross-chain business scene, the method comprises the following steps: designing a new cross-chain collaborative model, and realizing that interoperation can be completed on resources on multiple chains on the chain; designing a cross-chain consistency maintenance method for stable token and digital assets, wherein the method is used for ensuring the causality and final consistency of cross-chain interoperation in multiple chains; and designing a cross-chain consensus protocol based on a transaction mode and a random verifiable function to ensure the certainty of cross-chain operation. The invention is embedded into the block chain system in a plug-in manner in a service form, and has no invasion to the existing system. According to the invention, the cross-chain cooperation requirements among different cross-scene and cross-region block chain applications can be met.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a data consistency maintenance method for realizing cross-chain interoperability. Background technique [0002] As an important infrastructure for building the future value Internet, the blockchain has already landed enterprise-level applications in many fields such as reconciliation and settlement, cross-border payment, supply chain finance, judicial arbitration, government services, Internet of Things, and smart cities. However, at present, the interoperability between different blockchain applications is insufficient, and trusted data circulation and collaboration cannot be effectively carried out. Each blockchain has become an island of trust, which has largely hindered the integration and development of blockchain application ecology. If the blockchain wants to leapfrog to the real value Internet, a general and efficient blockchain cross-chain cooperation me...
