Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described below are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] Realization principle of the present invention is:

[0030] The first block chain sends the transaction data and the first multi-signature of the transaction data to the second block chain; after the second block chain is verified, it sends the receipt and the second multi-signature to the first block chain Re-signature; after the two blockchains are verified respectively, upload the transaction data, receipt and the first and second mu...

Abstract

The invention discloses a block chain cross-chain transaction method and system. The method comprises the following steps: a first block chain sends transaction data and first multiple signatures of the transaction data to a second block chain; after the second block chain passes verification, sending a receipt and second multiple signatures to the first block chain; and after the two block chains pass the verification, uploading the transaction data, the receipt and the first and second multiple signatures to the respective block chains, and sending a success message to the opposite side after the uploading is successful. According to the invention, the transaction data and the receipt can be stored on the chain only after the first and second multi-signatures are successfully verified, the security of the transaction is improved, and the first and second multi-signatures jointly generated by multiple nodes of the first block chain and the second block chain prove the current operation intentions of both parties and the acceptance of the transaction data, the multi-time calling of an intelligent contract is avoided, the system design is simplified, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of blockchain cross-chain transactions, in particular to a method and system for blockchain cross-chain transactions. Background technique [0002] Blockchain technology has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent" and "collective maintenance". Based on these characteristics, the blockchain technology realizes the non-tamperable data, traceable records and proof of the existence of time stamps, and then trustworthy information sharing and identity authentication among different entities (banks, enterprise credit platforms, legal supervision platforms, etc.) , credit and all kinds of report verification, has broad application prospects. [0003] With the development and application of blockchain technology, many types of blockchain projects have emerged. Since various blockchains use different underlying technologies, chains cannot ...
