Abstract

The invention discloses a data query method based on a block chain, a block chain processing device and a data query system, which are used for effectively improving the integral query efficiency. Themethod comprises the steps of obtaining related data of a target object, wherein the related data comprises integral data; storing the integral data into an intelligent contract of the blockchain, the intelligent contract including a contract sorting method, the contract sorting method being used for sorting the integrals of the target object according to the integral data of the target object; receiving a first query transaction request sent by the user side, wherein the first query transaction request comprises a target object identifier; calling an intelligent contract according to the target object identifier so as to call a contract sorting method to sort the points of the target object; and feeding back an integral sorting result of the target object to the user side.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain-based data query method, system and block chain processing device. Background technique [0002] At present, there are some point processing processes for point management. The inventor found that when using the block chain field to query point points, the traditional method is to read the point data from the block chain first, and then The point data is sorted. In this way, if the amount of point data is too large, it may take a long time to retrieve the point data, which reduces the efficiency of point query. Contents of the invention [0003] Embodiments of the present invention provide a blockchain-based data query method, a blockchain processing device, and a data query system to solve the technical problem of low efficiency of points query. [0004] A block chain-based data query method applied to a block chain processing device, the method com...
