Problems solved by technology

There are still some key problems in blockchain cross-chain technology. One is that the blockchain platform system is not unified, and the interaction interface also has its own specifications. Time is waiting for the return of the result, which is very inefficient

Embodiment Construction

[0028] The present invention will be described in detail below according to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] This application proposes an asynchronous cross-chain transaction query method based on the callback contract mechanism. The user can initiate a cross-chain transaction to the originating chain, and the originating chain is forwarded to the destination chain for processing. The callback contract associates cross-chain transactions and cross-chain result receipts and stores them in the local world state. Users can asynchronously query the execution results of cross-chain transactions through the f...

Abstract

The invention discloses an asynchronous cross-chain transaction query method and device based on a callback contract mechanism. Firstly, after a user initiates a cross-chain transaction to a cross-chain cluster, a first cross-chain transaction voucher is obtained, a cross-chain interaction process is completed by a block chain system, after cross-chain query is completed, a target chain returns a result receipt to an initiating chain, a cross-chain callback contract associates the first cross-chain transaction voucher with a third cross-chain transaction voucher. A user can query the third cross-chain transaction certificate through the first cross-chain transaction certificate and obtain the cross-chain result receipt through the third cross-chain transaction certificate. The problems that the original cross-chain transaction must wait synchronously, the efficiency is low and the stability is poor are solved, the asynchronous interaction mode greatly improves the processing capability of the block chain system, the interaction process and the execution result are both stored in the chain, the result is real and traceable and can be queried at any time, and the efficiency and the flexibility of cross-chain transaction query are improved.

Description

technical field [0001] The invention relates to the technical field of blockchain cross-chain and smart contracts, in particular to an asynchronous cross-chain transaction query method and device based on a callback contract mechanism. Background technique [0002] Blockchain cross-chain technology is a key technology to solve the isolated island of blockchain information, achieve blockchain network barriers, and realize data integration. Blockchain technology can solve the trust problem of all parties involved in the chain, while cross-chain technology needs to solve the problem of trust and intercommunication between chains. There are still some key problems in blockchain cross-chain technology. One is that the blockchain platform system is not unified, and the interaction interface also has its own specifications. Time is waiting for the result to return, which is very inefficient. [0003] A smart contract is a piece of code logic running on the blockchain network. It ...
