Problems solved by technology

The advantage of PoW as a consensus algorithm is wide adaptability and high security. The biggest disadvantage is that meaningless hash collision calculation (commonly known as mining) leads to a large amount of waste of electric energy.
[0003] PoET (Proof of Elapsed Time) is used as the consensus algorithm in the consortium chain of the blockchain, but the current PoET consensus algorithm relies on a specific model of CPU, and the consortium chain is to build blocks between specific institutions Therefore, it is acceptable to specify the unified use of a specific type of CPU, but the public chain system is not suitable for restricting the use of a specific type of CPU. Therefore, the current PoET is not suitable for application in the public chain

Abstract

The embodiment of the invention discloses a consensus method and device applied to miner nodes in a block chain system. A specific embodiment of the method comprises the following steps: acquiring accumulated unused lower limit duration; and executing the following accounting right determination operations in the trusted execution environment of the miner node: determining the current accumulatedunused duration of the miner node; determining whether the current cumulative unused duration is greater than the cumulative unused lower limit duration or not; and in response to determining that thecurrent cumulative unused duration is greater than the cumulative unused lower limit duration, determining that the miner node competes for the accounting right, and updating the current cumulative unused duration by using a difference between the current cumulative unused duration and the cumulative unused lower limit duration. According to the embodiment, the power consumption of the blockchainsystem is reduced.

Description

technical field [0001] The embodiment of the present application relates to the field of computer technology, and specifically relates to a consensus method and a blockchain system applied to miner nodes in a blockchain system. Background technique [0002] At present, the public chain of the blockchain mainly uses PoW (Proof of Work) as the consensus algorithm to determine which miner node obtains the bookkeeping right. The advantages of PoW as a consensus algorithm are wide adaptability and high security. The biggest disadvantage is that meaningless hash collision calculations (commonly known as mining) lead to a large amount of waste of electric energy. [0003] PoET (Proof of Elapsed Time) is used as the consensus algorithm in the consortium chain of the blockchain, but the current PoET consensus algorithm relies on a specific model of CPU, and the consortium chain is to build blocks between specific institutions Therefore, it is acceptable to specify the unified use of...
