Abstract

The present invention discloses a blockchain-based big data analysis method and system, in order to solve the problem of low node participation efficiency caused by a large amount of data in a block in the prior art. The method comprises: determining the legitimacy of data by using a node and sending the legal data; receiving the legal data and writing the legal data to the blockchain; synchronizing the blockchain by using the node and obtaining legal data; and writing the legal data into the blockchain, wherein the legal data is written into the blockchain in an index form. According to embodiments of the present invention, the data is written into the blockchain in an index form, the storage space of the data in the block is reduced, the storage space is saved from the data source, a large amount of data in the block is avoided, and the node participation efficiency is improved; and the technical scheme of the present invention is applicable to the field of big data.

Example Embodiment

[0057] Example one
[0058] This embodiment provides a block chain-based big data analysis method, which combines figure 1 Perform analysis, including:
[0059] The node determines the legality of the data and sends the legal data;
[0060] Receive legal data and write the legal data into the blockchain;
[0061] The node synchronizes the blockchain and obtains legal data;
[0062] The legal data is written into the block chain, and the legal data is written into the block chain in the form of index.

Example Embodiment

[0063] Example two
[0064] On the basis of the first embodiment, writing the legal data into the blockchain in the form of index includes:
[0065] Obtain the index value corresponding to the legal data;
[0066] The index value is converted into a tree structure, the tree structure includes at least three levels of leaf points, the number of leaf points contained in one level of leaf points is at least one, and the content corresponding to one leaf point in each leaf point in the middle layer is An index value segment of an index to be stored, and the content of the leaf point associated with the path from the root leaf point to the previous leaf point of a leaf point corresponds to the index value;
[0067] According to preset mapping rules, determine the corresponding mapping value of the content of each leaf point in the middle layer of the tree structure, and the length of the content of a node is greater than the length of the corresponding mapping value;
[0068] Replace the content of each leaf point in the middle layer with the corresponding mapping value, and store the replaced tree structure.

Example Embodiment

[0069] Example three
[0070] On the basis of the second embodiment, the process of converting the index value into a tree structure includes:
[0071] According to a preset segmentation rule, segment the index value with equal length to obtain at least two index value segments of equal length corresponding to each index to be stored;
[0072] Determine the layering of each index value segment after the segmentation in the middle layer according to the arrangement order of each index value segment after the segmentation in the corresponding index to be stored, and the layer corresponding to the index value segment is different;
[0073] For each index to be stored, the divided index value segments are stored hierarchically in the middle layer according to the determined layer;
[0074] The index value is stored in the leaf node of the leaf node layer of the tree structure, and the content of the node associated with the path from the root node to the previous node of any leaf node corresponds to the index value.
