Description
Technical field
The invention belongs to block chain technical field, specifically a kind of method of commerce based on block chain structure data.
Background technology
Block chain be with distributed data base identification, propagate and information-recording intelligent peer-to-peer network, be also referred to as worth
Internet is the integrated application mould of the computer technologies such as Distributed Storage, point-to-point transmission, common recognition mechanism, Encryption Algorithm
Formula.
Middle acute hearing 2008 in《Bit coin white paper》Middle proposition " block chain " concept, and founded bit in 2009
Coin community network, block chain shareable value system are imitated by numerous encryption currency first.Then, the block chain ecosystem is complete
Ball is constantly evolved, and the ether mill using intelligent contract as representative occurs.Intelligent contract can be in block chain network according to advance
The logic write executes automatically, is not necessarily to centralization node control.
In recent years, due to big data extensive use, the transaction of data is more and more frequent.Rely on the data of data trade platform
The problems such as transaction can not check data precipitation, data can not effectively solve.Therefore, design a kind of decentralization, can be to handing over
The data trade method of easy data examination, has great importance.
Invention content
It is an object of the invention to overcome the technical problem present on, provide a kind of based on block chain structure data
Method of commerce, do not set in block chain network Centroid preserve transaction data, by intelligent contract control both parties voluntarily at
It hands over, examination data do not select sample data voluntarily by the seller, randomly select a certain proportion of sample every time to ensure
Examination data can react true data cases.
To achieve the above object, the technical scheme is that in the following manner realizing：
A kind of method of commerce based on block chain structure data, including steps are as follows：
(1) full dose data are positioned over local holding area by seller node S, and the cryptographic Hash H of full dose data is write
Enter in block chain；
(2) the seller node S broadcasts the price P of the data by block chain network；
(3) buyer node B detects the quality of data by intelligent contract random sampling；
(4) by the intelligent contract, the buyer node B pays electronic money and obtains the data, the seller
Node S obtains the expense of the buyer node B payments.
Further, the holding area in the step (1) can only be visited by the intelligent contract in block chain network
It asks.
Further, the cryptographic Hash H in the step (1) is generated by the one-way Hash function of safety.
Further, the step (3) is to be performed by the intelligent contract of block chain, including steps are as follows：
(31) qualification exam：Intelligent contract first checks for whether carrying out data matter to the data before buyer node B
Amount detection, if carrying out data quality checking to the data before the buyer node B, the buyer node B does not have then
Qualification detects the quality of the data again；
(32) statistical data entry：Intelligent contract counts the local data conservation zone of the seller node S, and statistical data is total
Item number n；
(33) sampling item number is determined：Item number nc=n* sampling proportions of sampling round up when nc is not equal to integer；
(34) random sampling：Intelligent contract randomly selects nc datas, forms sample file；
(35) detection data quality：Sample file is sent to buyer node B, the buyer node B detections by intelligent contract
The quality of data decides whether to buy；
(36) intelligent contract will be in the event write-in block chain of the buyer node B detection data quality.
Further, the step (4) is to be performed by the intelligent contract of block chain, including steps are as follows：
(41) expense is paid：The buyer node B payment expenses P；
(42) transmission data：Intelligent contract sends the full dose data in the local data conservation zone of the seller node S
To the buyer node B；
(43) verify data：In the buyer node B calculate full dose data cryptographic Hash H1, and with the cryptographic Hash H
Compare, whether verify data has altered；
(44) closing the transaction：If cryptographic Hash H1=cryptographic Hash H, success of merchandising, the seller node S receive the buyer
The expense P of node B payments；If cryptographic Hash H1 ≠ cryptographic Hash H, closing of merchandising, the buyer node B is received in step (41)
The expense P of payment.
The present invention solve data trade platform to the precipitation of transaction data and data both parties can not logarithm it is investigated that testing
Information asymmetry the problem of, data trade ensures that entire transaction is reliable, the inspection of non-stop layer, data by being controlled by intelligent contract
Survey method is reasonable.

Embodiment one：
As shown in Figure 1, each node in the present embodiment is divided into block sequence and the holding area regions Liang Ge.It is all
For node by a distributed account book of the common maintenance of block chain in block sequence, the node is stored in the holding area in node
The data to be sold, holding area can only carry out relevant operation by intelligent contract.
As shown in Fig. 2, a kind of method of commerce based on block chain structure data, includes the following steps：
(1) seller node S intends to sell data set D with 100 yuan of price, and the total number of data set D is 10000.It sells
Fang Jiedian S are stored in the holding area in node under the control of intelligent contract, by data set D, while intelligent contract calculates
Cryptographic Hash H is written in block chain and submits the block chain, in case all nodes can be inquired by the cryptographic Hash H for going out data set D.
(2) seller node S broadcasts 100 yuan of the information and price of data set D to be vended in block chain network.
(3) the buyer node B in block chain network intends to buy data set D, and the request detection quality of data executes intelligence
Contract.
(4) intelligent contract first checks for the quality whether buyer node B detected data set D in the past, to prevent buyer node B
Data are gradually obtained by repeating detection data quality.In this example, the quality of data set D was not detected before buyer node B.
(5) intelligent contract from the holding area of seller node S according to sampling proportion randomly drawing sample data, this example
The middle sampling proportion that sets is 1%, then total 10000*1%=100 items of sample data.Intelligent contract sends out this 100 sample datas
Buyer node B is sent, while record buyer node B has crossed the quality of data set D after testing in block chain, submits block.
(6) buyer node B decides whether to buy data set D after receiving sample data, and buyer node B determines purchase in this example
Data set D.
