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 co...
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 corre...
