Embodiment 1

[0028] figure 1 It shows the implementation process of the blockchain data indexing method provided by Embodiment 1 of the present invention. For the convenience of explanation, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0029] In step S101, the transaction data in the preset block chain is traversed to obtain a data pattern group in the transaction data that conforms to the preset longest frequent common pattern, and the data pattern group includes multiple data patterns.

[0030] In the embodiment of the present invention, the data pattern embodies the structural form of the data, the data pattern group includes multiple data patterns, the longest frequent common pattern refers to a group of data patterns, and this group of data patterns consists of no less than m data patterns Composition, and this group of data patterns appear at least k times at the same time. When a blockchain data index request is rece...

Embodiment 2

[0040] figure 2 It shows the implementation flow of the blockchain data query method provided by the second embodiment of the present invention. For the convenience of explanation, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0041] In step S201, a blockchain data query request input by a user is received, and query keywords included in the blockchain data query request are obtained.

[0042] The embodiment of the present invention is applicable to the blockchain, especially applicable to the blockchain with the corresponding index view chain obtained by using the first embodiment of the present invention, so that it is convenient for the user to query the transaction data in the blockchain. In the embodiment of the present invention, before receiving the blockchain data query request input by the user, first traverse the transaction data in the blockchain, obtain the data pattern group in the transaction data ...

Embodiment 3

[0048] image 3 The structure of the blockchain data indexing device provided by the third embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, including:

Abstract

The invention is applicable to the technical field of computer, and provides a block chain data indexing and querying method, a device, a piece of equipment and storage media. The method includes thefollowing steps: traversing transaction data in a preset block chain; getting a data mode group which conforms to a preset most frequent public mode in the transaction data, wherein the data mode group includes multiple data modes; setting up the corresponding indexed view chain for each data mode in the data mode group; establishing the corresponding index of the transaction data in the block chain; and according to the corresponding relation between the transaction data and each of the data mode, storing the index in the corresponding indexed view of the indexed view chain corresponding to each data mode so as to establish the data index of the block chain, and further improve the query efficiency of the data in the block chain.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a block chain data index and query method, device, equipment and storage medium. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is an Internet database technology. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. It is decentralized, open and transparent. , safe and reliable features. Each block in the blockchain contains a block header and a block body. The role of the block header is to link to the previous block to provide integrity for the blockchain. The block body contains the transaction data during the block creation process. When it is necessary to query the transaction data in the blockchain, the transaction data of the current block can be queried through the block body, and the previous bl...
