The invention relates to a block chain data processing method, in particular to a consumption data storage, data verification and data source tracing method based on a block chain.
Background
With the rapid development of internet technology, network information is richer, network transactions are more frequent, network original works are layered endlessly, the informatization construction of electronic government affairs and enterprises and public institutions is increasingly perfect, and the data volume is continuously increased. The people enjoy the internet technology to provide convenience for life and work, and simultaneously face potential risks and hidden dangers brought by the internet and informatization.
A large amount of electronic data is generated in the information interaction process of the Internet or the information construction process of electronic government affairs and enterprises and public institutions, and the electronic data has the problems of easy disappearance, easy change, no time identification, low copying cost, easy infringement and the like. How to ensure that the originality of original electronic data is not infringed, ensure the safe and reliable storage of the electronic data, and achieve tamper resistance, traceability and the like is a problem which is needed urgently in the current data resource era.
Disclosure of Invention
The invention aims to solve the technical problems that electronic data are easy to disappear, change and infringe, time marks are not generated, the copying cost is low, and the electronic data are easy to infringe.
The invention is realized by the following technical scheme:
a consumption data storage, data verification and data source tracing method based on a block chain comprises the following steps:
A. establishing an industry block chain, wherein a user of each industry block chain is a node, and all users of the industry block chain designate a plurality of nodes as bookkeepers;
B. distributing a unique check code for each node in the step A, and establishing a check code list in the network layer of the industry block chain established in the step A; establishing an industry block chain block retrieval directory;
the method also comprises the following data storage steps:
C. when transaction data are generated, a node generating the transaction initiates a request to create a new transaction data block, and an industry block chain broadcasts the transaction data block to all the accountants on the block chain;
D. b, the bookkeeper verifies the transaction data block requested in the step C, and the step E is carried out after the verification is passed;
E. c, the node initiating the request stores the check code, the transaction data and the timestamp in a transaction data block and stores the transaction data information in a retrieval directory, and the transaction data block is added to a main chain of an industry block chain;
the method also comprises the following data checking steps:
F. after the transaction data block is added to the main chain of the industry block chain in the step E, the industry block chain extracts the check code in the transaction data block and a check code list of a network layer;
G. the trade block chain obtains a node corresponding to the check code by comparing the check code with the check code list, whether the node is the same as a node recorded by the trade data in the trade data block is judged, if yes, the check is passed, and if not, error information is broadcasted through the trade block chain;
the method also comprises the following data tracing steps:
H. when data tracing is needed, the node retrieves the corresponding transaction data block through the industry block chain block retrieval directory, and directly reads transaction data on the transaction data block through the industry block chain data layer after the corresponding block is retrieved.
The industry blockchain means that a plurality of preselected nodes are designated as bookkeeping persons in a certain group, the generation of each block is jointly determined by all the preselected nodes, and other access nodes can participate in transactions without inquiring about the bookkeeping process. Generally, a blockchain system consists of a data layer, a network layer, a consensus layer, a stimulus layer, a contract layer, and an application layer. The data layer encapsulates a bottom layer data block, basic data such as related data encryption and time stamp and a basic algorithm; the network layer comprises a distributed networking mechanism, a data transmission mechanism, a data verification mechanism and the like; the consensus layer mainly encapsulates various consensus algorithms of the network nodes; the incentive layer integrates economic factors into a block chain technology system, and mainly comprises an economic incentive issuing mechanism, an economic incentive distributing mechanism and the like; the contract layer mainly encapsulates various scripts, algorithms and intelligent contracts and is the basis of the programmable characteristic of the block chain. In the model, a chained block structure based on a timestamp, a consensus mechanism of distributed nodes, economic excitation based on consensus computing power and a flexible programmable intelligent contract are the most representative innovation points of the block chain technology. For the scheme, since economic excitation is not involved, an excitation layer is not needed, and compared with the traditional block chain network, the block chain network is simpler to build.
Further, the consensus mechanism of the bookkeeper adopts a DPoS mechanism. The DPoS mechanism further reduces the number of the nodes to 101, so that the energy consumption of the whole network is further reduced on the premise of ensuring the network security, and the network operation cost is lowest. The DPoS mechanism is more decentralized. The DPoS mechanism also has faster acknowledgement speed. Each block is 10 seconds in time, one data exchange, i.e. about 1 minute for 6-10 acknowledgments, and a complete 101 block period of only about 16 minutes. Whereas the PoW mechanism takes 10 minutes to generate a block and 1 hour for one data exchange. The PoS mechanism also requires approximately 1 hour to confirm a transaction.
Further, the information stored in the retrieval directory includes information of the node initiating the transaction and information of the transaction object.
Further, the method for verifying the transaction data block requested in step C by the bookkeeper in step D includes the following steps:
d1, matching a unique verification password for each node, and packaging the verification passwords of all nodes as a verification program;
d2, when the node generating the transaction initiates a request, the node sends the externally input verification password to each bookkeeper at the same time;
d3, the bookkeeper passes the verification password sent by the verification node of the verification program, if the verification password is consistent with the password recorded in the verification program, the verification is passed, otherwise, the verification is not passed.
And further, the method comprises a method for grading the nodes during data tracing, wherein when the retrieval directory is established in the step B, the retrieval directory is graded, each node is classified into a corresponding grade according to the grading of the retrieval directory, and when the data tracing is performed in the step H, the node can only retrieve the data of the corresponding grade in the retrieval directory.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. according to the consumption data storage, data verification and data source tracing method based on the block chain, the block chain system is simple and convenient to build;
2. according to the consumption data storage, data verification and data tracing method based on the block chain, consumption data can be effectively stored;
3. the consumption data storage, data verification and data source tracing method based on the block chain can effectively verify and trace the data stored in the block chain.
