Embodiment Construction

[0067] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0068] The blockchain system has the characteristics of decentralization, which is different from traditional centralized servers. Since the blockchain system has no centralized nodes, it needs a consensus mechanism to maintain normal operation. For example, the consensus mechanism includes the POW algorithm. Based on the POW algorithm, the block The chain system can realize the consensus verification of blocks.

[0069] The POW algorithm is a strategy to deal with denial of service attacks and other service abuses. A workload proof refers to a data calculation that meets certain conditions. It is ...

Abstract

The invention relates to the technical field of block chain, in particular to a mining method and device based on block chain, a mining machine and a block chain system. The method comprises: a miningtask request is sent to each miner node, wherein, the mining task request carries a search number, and the search number is used for instructing each miner node to search the hash value to be verified corresponding to the search number in the search space of each random number, and the search space of any two random numbers has the same search number, and the hash value to be verified corresponding to the same search number is different; a hash value to be verified corresponding to the search number uploaded by each miner node is received; the current block is validated based on the hash value to be validated. On the one hand, because the same search number corresponds to different hash values to be verified, the proxy node can avoid repeating the same verification work, thereby saving energy consumption relatively.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain-based mining method and device, a mining machine and a blockchain system. Background technique [0002] Some blockchain systems support the proof of work mechanism (Proof of Work, POW). According to the proof of work mechanism, each miner node independently completes the calculation of the proof of work. account rights. [0003] In the process of realizing the present invention, the inventor found that the traditional technology has at least the following problems: Since each miner node independently completes the workload proof, each miner node is easy to repeatedly calculate the same workload, resulting in energy waste. Contents of the invention [0004] An object of the embodiments of the present invention is to provide a blockchain-based mining method and device, a mining machine and a blockchain system, which can save energy. [0005] In order to ...
