Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted here that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

[0034] Before specifically expressing a method and system content for solving cross-chain coupling described in the present invention, in order to facilitate understanding, here is an overview of the current difficulties encountered in cross-chain transactions. In the description of cross-chain transactions in the existing technology, when one chain transfers assets to another chain, it needs to freeze the assets on its own chain first, and then tell the other party "I have frozen it, you can receive it", and then the other party will come Verify on my chain whether it is really frozen, and if it is found that it is ...

Abstract

The invention discloses a method for addressing cross-chain coupling. The method comprises the steps that a local chain block and transaction information located on the local chain block are set; after the block processes the out-of-chain transaction, the establishment of an out-of-chain negative account list is completed, and negative account details are checked; the local chain block queries anoff-chain node having a transaction with the local chain block and an off-chain block where the node is located, establishes node connection, sends a negative account list and requests confirmation ofthe off-chain block; after the out-of-chain block confirms the negative account list, the negative account is cleared, and when the local chain block checks that the negative account is zero, out-of-chain transaction processing is recovered. The invention further provides a system for solving the cross-chain coupling, the system comprises a freezing manager, an off-chain verification manager anda credit granting manager, and the problem that in the cross-chain transaction, the intra-chain transaction and the cross-chain transaction have reliability at the same time, and meanwhile the intra-chain transaction and the cross-chain transaction are decoupled is effectively solved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for solving cross-chain coupling. Background technique [0002] Blockchain is the most important infrastructure in the future credit era, and this infrastructure will be composed of many blockchains, so cross-chain data interaction and cross-chain asset transfer between many blockchains will be a necessary and important component part. A single blockchain originally operates independently and autonomously, but once it involves cross-chains, it may need to rely on the reliability of other chains. If one chain becomes dependent on the reliability of another chain, the reliability of this chain The reliability will decrease exponentially, because the other chain becomes unavailable, then it is impossible to verify the accuracy of the cross-chain transfer data or assets of another chain; that is, if the other chain is not relied on, the other chain will be r...
