Blockchain multi-chain management method and device

Abstract

The invention discloses a block chain 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 block chains are stored in each block chain node, and the plurality of block chains comprise a main chain and at least one sub-chain. The block chain multi-chain management method comprises the following steps: when a first sub-chain in a first sub-chain consensus node registers and joins in the plurality of block chains of the block chain multi-chain system, the main chain consensus node acquires a registration request sent by the first sub-chain consensus node; the main chain consensus node verifies the legality of the first sub-chain consensus node according to the registration request; and when it is verified that the first sub-chain consensus node is legal, the main chain consensus node manages the first sub-chainconsensus node through a preset multi-chain smart contract. 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

technical field [0001] The present invention relates to the field of computer technology, in particular to a block chain multi-chain management method and device. Background technique [0002] 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 layer, a network layer, a consensus layer, an incentive layer, a contract layer, and an application layer. In a narrow sense, a blockchain is a system that connects data blocks in sequence A chained data structure composed of various methods...

Problems solved by technology

[0003] 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

[0004] 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.
