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 a
