Chain identifier generation method and device, chain cluster management method and system, and medium

Abstract

The invention discloses a chain identifier generation method and device, a chain cluster management method and system and a medium, and relates to the technical field of block chains and a block chain cluster system, hardware comprises a computer readable storage medium and a processor, software comprises at least two block chains, the computer readable storage medium stores a computer program, the processor can execute the computer program. When the computer program is executed, a block chain cluster management method and a block chain identifier generation method can be realized, and according to the management method, each block chain in the chain cluster has a chain identifier with uniqueness in the chain cluster; the hash value of each block is combined with the chain identifier of the block chain to which the block belongs to form an addressing identifier of the block, and the block can be inquired according to the addressing identifier. The block chain identifier generation method comprises the step of generating a chain identifier of each block chain according to a block in the block chain. Therefore, the problem of block hash value collision can be solved, and a chain cluster can be established to solve the problem of multi-chain collaboration.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method and device for generating chain identifiers, a method for managing chain clusters, a system, and a medium. Background technique [0002] The blockchain has the technical characteristics of reliable data, traceability, and non-tampering. In recent years, the application of blockchain technology has become more and more extensive. More and more units have established their own blockchains to store information. Each blockchain independent of each other. Nowadays, various units need to cooperate more, and the lack of interoperability between their respective blockchains is not conducive to the collaborative work between various units. In the existing technology, there is a practice of establishing a big data center to realize information sharing and exchange, and to facilitate collaboration among various units. However, this approach cannot solve the problem of...

Problems solved by technology

However, if you manage multiple blockchains and include more than one blockchain, the hash values ​​of the blocks on different blockchains may be the same, that is to say, the hash value collision problem may occur. At this time, if the block is queried according to the hash value of the block, multiple blocks may be queried, resulting in confusion and serious consequences
