Problems solved by technology

As a decentralized distributed shared database, the existing blockchain requires each node to store complete block data. With the increase in the number of nodes in the system and the complexity of transactions, nodes need more and more local storage space to Store block data, which has become a bottleneck in the actual application of the blockchain; at the same time, the current blockchain solution does not support temporal data processing, and the sequential access based on block files in the blockchain hinders efficient query processing

Embodiment Construction

[0068] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0069] By adopting a pipeline-based data encoding scheme to encode the data to store the encoded data in the blockchain, and slice the locally stored block data to reconstruct the block data and realize the blockchain storage optimization; at the same time, a time-based index construction algorithm is used to establish a temporal index of block data, reducing access to block data and databases, and achieving more efficient data retrieval. refer to figure 1 As shown, it is a schematic diagram of a blockchain-based fast data retrieval method provided by an embodiment of the present invention.

[0070] In this embodiment, the blockchain-based fast data retrieval method includes:

[0071] S1. Obtain the data to be stored, and perform encoding processing on the data to be stored by using a pipeline-based data encoding sc...

Abstract

The invention relates to the technical field of block chains, and discloses a block chain-based rapid data retrieval method, which comprises the steps of obtaining to-be-stored data, and performing encoding processing on the to-be-stored data by utilizing a pipeline-based data encoding scheme to obtain encoded data; storing the coded data into a block chain, and storing a copy of the to-be-storeddata into a block chain node by utilizing a time-based copy storage method; slicing the data stored in the blockchain by utilizing a data slicing mode based on the erasure code to obtain sliced data based on the erasure code; utilizing an index construction method based on a time sequence to construct a time sequence index; and utilizing the time sequence index of the data to quickly retrieve thedata. The invention further provides a rapid data retrieval system based on the block chain. According to the invention, data retrieval is realized.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a fast data retrieval method and system based on block chains. Background technique [0002] With the rapid popularization of social networks, smart hardware, mobile Internet and the Internet of Things, the hidden value of big data can be displayed to a greater extent, and a new era that pays more attention to data value and data openness is quietly coming. What follows is that business, scientific research, public services and other fields all put forward urgent needs for the open sharing of big data. However, due to the lack of a safe and credible data sharing environment, big data is still used by various government agencies, commercial enterprises, and scientific research institutions. Even individual storage and control form a "data island", which seriously affects the sharing and opening of big data. [0003] Blockchain has attracted the attention of various i...
