Blockchain multi-chain management method and device

Abstract

The invention discloses a blockchain multi-chain management method and device. The blockchain multi-chain management method is applied to a blockchain multi-chain system. The blockchain multi-chain system comprises a plurality of blockchain nodes, wherein a plurality of blockchains are stored in each blockchain node, and the plurality of blockchains comprise a main chain and at least one sub-chain. The method comprises the following steps when a second sub-chain in the plurality of blockchains exits the plurality of blockchains, the main chain consensus node obtains an exit request sent by a second sub-chain consensus node, wherein the exit request comprises an identity identifier of the second sub-chain; the main chain consensus node verifies the legality of the exit request; if the exitrequest is legal, the main chain consensus node operates a preset multi-chain smart contract, so that the second sub-chain quits the plurality of blockchains. According to the method and the device, the problem that the existing blockchain multi-chain management data is easy to make mistakes is avoided, the overall performance of a blockchain system is improved, and a feasible scheme is provided for future blockchain multi-chain management.

Description

[0001] This application is a divisional application of the Chinese patent application submitted on August 15, 2019, with the application number 201910753300.X and the application name "blockchain multi-chain management method and device". technical field [0002] The present invention relates to the field of computer technology, in particular to a block chain multi-chain management method and device. Background technique [0003] Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin. The underlying technology of Bitcoin is a series of data blocks associated with cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify the validity of its information and generate the next block. Generally speaking, the blockchain multi-chain system consists of a data l...

Problems solved by technology

[0004] In the blockchain ecosystem, an increasingly inevitable problem is that there will be more and more blockchain networks. The existence of a multi-chain environment is mainly due to several factors: 1. Many blockchains The nodes will be limited to the participants of a certain thing or process, such as a supply chain. The problem is that many organizations will have multiple sub-chains in one sub-scenario, and large organizations will have multiple sub-scenarios. As a result, a company will Unknowingly generate multiple blockchain networks that are scattered and difficult to manage uniformly; 2. Due to the high demand for the second traffic of the blockchain itself, some blockchains will use data sharding to distribute daily transactions Running on multiple blockchains will also cause management difficulties

[0005] At present, there is no real solution that can effectively solve the above-mentioned problems in the multi-chain environment. Users currently need to manage different blockchains in multiple blockchain nodes separately. The operation is cumbersome, the data is prone to errors, and the system efficiency is low.
