Description
Technical Field
The invention relates to the technical field of big data, in particular to a data tracing method based on a block chain.
Background
The block chain is a term in the technical field of information, and essentially, the block chain is a shared database, and data or information stored in the shared database has the characteristics of 'unforgeability', 'whole-course trace', 'traceability', 'open transparency', 'collective maintenance' and the like.
Data tracing is an emerging research field, which is born in the 90 s of the 20 th century. At first, some documents refer to them as data logs or data archives, and later, most documents refer to them as data origins, and have the intention of tracking the data origins and reproducing the historical states of the data, and are referred to as data tracing herein, so that from the application point of view, the tracing process and method are emphasized, and the following problems mainly exist in the existing data tracing method based on the block chain.
1. The existing block chain mass data tracing adopts single machine operation, and the efficiency of block chain tracing is reduced.
2. The existing block chain data tracing method adopts a single server, so that the requirement of single machine data tracing is influenced.
Disclosure of Invention

The invention realizes the purpose through the following technical scheme:
a data tracing method based on a block chain comprises the following steps:
step 1: traversing the block chain according to the block generation order;
step 2: mapping resource transfer records of the block chain to a plurality of servers based on an address of each block, wherein the address comprises an input address or an output address;
and step 3: each server constructs a sub spanning tree set according to the mapping stored block resource transfer records;
and 4, step 4: merging the sub spanning tree sets constructed by the servers to construct a spanning tree, thereby realizing the tracing of the block chain.
Furthermore, the information and data established for the blocks in step 1 are decomposed into detailed sequence traversal blocks, and are sorted and stored according to a certain sequence.
Furthermore, the convenient output address and the convenient input address in step 2 query the block chain to which the server belongs, so that the sharing range of the block can be found in the fastest time.
Furthermore, in the step 4, the spanning trees are combined and constructed for the servers, so that the tracing of the block chain data is facilitated, and the efficiency of tracing the massive data block chains of the single machine is improved.
The invention has the beneficial effects that:
1. according to the block chain data tracing method, the block chain data tracing is facilitated by merging and constructing the spanning trees for the servers, and the efficiency of block chain tracing of mass data of a single machine is improved.
2. The block chain data tracing method and the block chain data tracing system facilitate the output of the address and the input of the address, query the block chain to which the server belongs, can find the sharing range of the block in the fastest time, and meet the requirement of single-machine data tracing.
