Problems solved by technology

[0003] However, the data on the chain of the blockchain network is a data island, and different blockchains cannot be interconnected, which hinders the further development of the blockchain application ecology
Cross-chain technology is used to solve the interoperability between two or more blockchains, allowing data to cross the barriers between chains and allowing value to circulate between different blockchains, but the existing ones that can be realized Cross-chain technology often has the problem of data leakage during the cross-chain process, and there are differences between the standards of different chains and the business of different chains, and there are problems that are difficult to supervise

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The purpose of the present invention is to provide a blockchain cross-chain communication method, which can realize blockchain cross-chain communication without synchronous verification of block headers, can reduce storage and computing resource consumption, can prevent data leakage in the cross-chain process, and can Realize the supervision of cross-chain data.

[0029] In order to make the above objects, features and advantages of the present inventio...

Abstract

The invention provides a block chain cross-chain communication method, which comprises the following steps that: a source block chain sends a cross-chain processing request to a verification party, the verification party sends a target query request to an organization node in a target block chain according to the cross-chain processing request, the organization node receives a target data query request, carries out retrieval through the target data query request to obtain target data, and sends the target data to the source block chain; the verification party verifies the obtained organization node signature and sends the target data to the source block chain and the supervision chain to generate a data supervision request and send the request to the source block chain and the target block chain, the source block chain and the target block chain verify the request and send the supervision data to the supervision chain after the verification is passed, and the supervision chain sends the supervision data to the source block chain and the target block chain after the verification is passed. And the data is stored on a data supervision account book. According to the block chain cross-chain communication method provided by the invention, block chain cross-chain communication can be realized, synchronous verification of a block head is not needed, consumption of storage and computing resources can be reduced, data leakage in a cross-chain process can be prevented, and supervision of cross-chain data can be realized.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain cross-chain communication method. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The blockchain has the characteristics of decentralization, non-tampering, traceability, traceability, collective maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for the creation of trust in the blockchain. [0003] However, the data on the chain of the blockchain network is a data island, and different blockchains cannot be interconnected, which hinders the further development of the blockchain application ecology. Cross-chain technology is used to solve the interoperability between two or more blockchains, allowing data to cross t...
