Embodiment Construction

[0020] A blockchain-based data traceability method, which includes the following steps:

[0021] Step 1: Traverse the blockchain according to the block generation order;

[0022] Step 2: Map the resource transfer records of the block chain to multiple servers based on the address of each block, wherein the address includes an input address or an output address;

[0023] Step 3: Each server builds a sub-spanning tree set according to the block resource transfer records stored in the map;

[0024] Step 4: Merge and process the sub-spanning tree sets built by each server to build a spanning tree, so as to realize the traceability of the blockchain.

[0025] Preferably, the information and data created for the blocks in step 1 are decomposed into detailed order to traverse the blocks, and are arranged and stored in a certain order.

[0026] Preferably, in the step 2, for the convenient output address and input address, query the block chain to which the server belongs, and the s...

Abstract

The invention discloses a data tracing method based on a block chain. The data tracing method comprises the following steps: step 1, traversing the block chain according to a block generation sequence; 2, mapping the resource transfer record of the block chain to a plurality of servers based on the address of each block, wherein the address comprises an input address or an output address; and 3, enabling each server to construct a sub spanning tree set according to the block resource transfer record stored by mapping. The method has the advantages that the servers are combined to construct thespanning tree, tracing of block chain data traceability is facilitated, the single-machine mass data block chain traceability efficiency is improved, the sharing range of the block can be found in the shortest time for conveniently outputting addresses and inputting addresses and querying the block chain to which the servers belong, and the requirement of stand-alone data traceability is met.

Description

technical field [0001] The present invention relates to the technical field of big data, and the present invention relates to a data traceability method based on block chain. Background technique [0002] Blockchain is a term in the field of information technology. In essence, it is a shared database in which the data or information stored has the characteristics of "unforgeable", "full trace", "traceable", "open and transparent", "collective Based on these characteristics, blockchain technology has laid a solid foundation of "trust", created a reliable "cooperation" mechanism, and has broad application prospects. [0003] Data provenance is an emerging research field, which was born in the 1990s. At the beginning, some literature called it data log or data archive. Later, most literature named it data origin, which means to trace the origin of data and reproduce the historical state of data. This paper calls it data traceability, from From the perspective of application, ...
