Embodiment Construction

[0038] Various exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of methods and systems according to various embodiments of the present disclosure. It should be noted that each block in a flowchart or a block diagram may represent a module, a program segment, or a part of a code, and the module, a program segment, or a part of a code may include one or more An executable instruction for a specified logical function. It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or they may sometimes be executed in the reverse order, depending upon the functionality involved. It should also b...

Abstract

The invention discloses a cross-chain communication method, a cross-chain communication device and a cross-chain communication system based on a block chain. The cross-chain communication method comprises the steps that: at least one node in a first sub-chain sends first transaction information to at least one node in a second sub-chain for representing that the first sub-chain requests to acquireevent transaction information of the second sub-chain; at least one node in the second sub-chain determines, according to the received first transaction information, whether the first sub-chain has the right to acquire the event transaction information of the second sub-chain; and if the first sub-chain has the right to acquire the event transaction information of the second sub-chain, at least one node in the second sub-chain sends second transaction information to at least one node in the first sub-chain for indicating that the first sub-chain has the right to acquire the event transactioninformation of the second sub-chain.

Description

technical field [0001] The present invention relates to blockchain technology, in particular to a blockchain-based cross-chain communication method, device and system. Background technique [0002] Blockchain (Block Cham) technology is based on a decentralized peer-to-peer network, which combines cryptography principles with consensus mechanisms to ensure the coherence and continuity of distributed data at each node, and realize instant verification, traceability, and difficulty of transaction information. Tampering and other characteristics, thus creating a set of private, efficient and secure distributed trust system. [0003] So far, all blockchain systems, whether they are public chains or consortium chains, exist in the form of isolated islands. It is difficult to establish a communication channel between chains. However, isolated islands of transaction information have been proven to be an inefficient way to use the Internet, and have been abandoned by people in the ...
