A multi-block chain network networking method, device and system

Abstract

The embodiment of the present invention discloses a multi-blockchain network networking method, device and system, the method comprising: obtaining a tree-shaped hierarchical structure corresponding to multiple blockchain networks to be networked, wherein the tree-shaped hierarchical A tree node in the structure corresponds to a blockchain network to be networked; according to the parent-child node relationship in the tree hierarchy structure, establish cross-chain communication between parent-child blockchain networks associated with parent-child nodes in multiple blockchain networks Connect to form a tree-shaped blockchain network; determine the chain number corresponding to each blockchain network according to the tree-shaped hierarchical structure, and generate each block chain number according to the chain number and the node number of each blockchain node in the corresponding blockchain network. The identity identification of the block chain node in the tree-shaped block chain network. The technical solutions of the embodiments of the present invention can improve the scalability and interoperability of the blockchain network, thereby supporting complex and scalable application scenarios of multi-service chains and multi-morphic chains.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of block chains, and in particular to a multi-block chain network networking method, device and system. Background technique [0002] Due to the integration of distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm, blockchain technology can effectively solve the problem of fraudulent behavior in the process of data circulation in the system in the traditional transaction mode, and simplify the process and reduce some Unnecessary transaction costs and institutional costs. [0003] Existing blockchain technology, such as Bitcoin or Ethereum, only circulates value in its own chain, and each chain is an independent, vertical closed system, gradually becoming incompatible information islands, more like a "local area network". The cooperation and interconnection of different blockchain platforms in different application fields becomes crucia...

AI Technical Summary

Problems solved by technology

[0004] In the process of implementing the present invention, the inventor found that the existing block chain technology has the following defects: in the side chain technology, there are communication delays between the main chain and the side chain, low security, poor synchronization and other problems that are difficult to solve

The lightning network is only suitable for frequent transactions between a fixed group of parties, and if the user's transaction goals are random and the transaction behavior occurs occasionally, it will lead to a decrease in efficiency

In addition, transactions are tracked through lightning channels instead of the main blockchain, which involves another transparency issue

It is very complicated to adopt sharding technology based on the existing blockchain. The main challenges include security issues such as cross-shard transactions and single shard management, and further scalability issues have not been resolved.

However, the development of cross-chain technology is more difficult, and the performance of existing cross-chain solutions has not been actually verified
