Specific embodiment
On the basis of existing block chain technology, in order to shorten the time for inquiring shared economic data from block chain, mention
Height inquires the efficiency of shared economic data from block chain, provides the embodiment of the present invention.
Embodiments herein, suitable for sharing the inquiry of economic data, share economic data include shared economic time,
Share economic user and shared economic content；Shared economic content can be related to each ken, such as known to user
Shared automobile, shared bicycle, shared parking stall etc..In other words, the resource that user can would sit idle for passes through block chain node
It is stored on block chain, other users can be selected according to their own needs.Such as: idle bicycle, it is idle can
To be used to do time, the idle time that can be used to do washing oil smoke machine of housekeeping, issued by block chain node in block chain
On, other users in need can be used or be bought accordingly by block chain.These process datas are all recorded in area
On block chain.
In embodiments of the present invention, when user needs to obtain some shared economic data, user passes through client, according to
Shared economic data mark (such as: User ID) obtains corresponding shared economic data from database.While in order to guarantee to share
The safety of economic data, client calculate the cryptographic Hash for getting shared economic data, and by the cryptographic Hash of calculating in block
Verified, i.e., the cryptographic Hash stored in the cryptographic Hash of calculating and block chain be compared on chain, when calculating cryptographic Hash with
When the cryptographic Hash stored on block chain is consistent, the shared economic data for determining that client is obtained from database is not tampered with, and is
Really.
Flow chart below with reference to the querying method of the shared economic data of Fig. 1 is applied to provided in an embodiment of the present invention
The shared economic data querying method of block chain is illustrated.
As shown in Figure 1, the executing subject of this method is client, method includes the following steps:
S101, client inquire the shared economic data, the number according to shared economic data mark from database
It according to the shared economic data in library is obtained from block chain.
In this embodiment, the time that shared economic data is inquired to shorten client from block chain, client is improved
The efficiency of shared economic data is inquired at end, is first downloaded the data of the shared economy on block chain, is parsed and store and arrives database
In, which can be conventional database, for storing data.The database can be specifically a server or its
His equipment for storing data.
When user, which needs to inquire some, shares economic data, by client, according to the attribute information of shared economy
(identification information) is inquired from database and obtains the data of the shared corresponding shared economy of economic attribution information.
In one embodiment, sharing economic attribute information can be the mark for sharing economy, which is uniquely to mark
Know.Economic attribute information is shared to be also possible to share the information such as the title of economy.
In one embodiment, the Data Identification of the shared economy includes User ID, shares the one of economic content mark
Kind or two kinds；The shared economic data includes user data, shared economic content data and shared economic time data, institute
Stating shared economic content data includes that shared car data, shared parking space number are one or more according to, shared voluntarily car data.
For example, user is total by client query when user needs the shared economy of inquiry to be identified as the shared economic data of A
Enjoy the shared economic data of economic entitled A；In one embodiment, client sends inquiry request, the inquiry to database
It include shared economic mark A in request；After database receives the inquiry request, this is shared to the shared economy of economic title A
Data feedback is to client.
S102, client carry out the first Hash operation according to the shared economic data and obtain the first cryptographic Hash.
When client receives the data for sharing economy, such as client receives the shared warp that shared economy is identified as A
When data of helping, the shared economic data that client is identified as A to shared economy carries out Hash calculation, obtains cryptographic Hash, the Hash
Value is also known as the first cryptographic Hash.
It should be noted that, in order to distinguish information, such as cryptographic Hash, " first " has been used in the inventive embodiments, " the
Two ", but in embodiments of the present invention, " first " and " second " is used only for distinguishing things, without limitation to information itself.
First cryptographic Hash is compared by S103, client with the second cryptographic Hash, and second cryptographic Hash is the block
The shared economic data stored on chain carries out the cryptographic Hash that the second Hash operation obtains.
In order to guarantee the number from the data and the shared economy obtained from block chain of the shared economy obtained in database
According to consistent, that is to say, that, need to be shared by what is obtained from database to guarantee that sharing economic data in database is not tampered with
The data of the shared economy stored in economic data and block chain compare.
And economic data is shared when storing on block chain, storage is the Hash shared after economic data conversion
Value obtains the Hash of shared economic data for this purpose, client calculates the data of the shared economy obtained from database
It is worth (also known as the first cryptographic Hash), is then compared with second cryptographic Hash for sharing economic data stored on block chain
It is right, to determine that the data of the shared economy obtained from database are not tampered with, with the shared economic data on block chain
Unanimously, i.e., the data of the shared economy got from database be correctly, it is safe.
In one embodiment, first cryptographic Hash is compared by the client with second cryptographic Hash, packet
Include: the client sends the first cryptographic Hash on the block chain, will on the block chain by verifying intelligent contract
First cryptographic Hash is compared with the second cryptographic Hash.
In one embodiment, first cryptographic Hash is compared by the client with second cryptographic Hash, packet
Include: the client obtains the second cryptographic Hash from the block chain, and by first cryptographic Hash and second cryptographic Hash
It compares.Detailed process may is that client sends acquisition request to some block chain node of block chain, to obtain on block chain
Second cryptographic Hash of the shared economic data；When client gets the second cryptographic Hash of the shared economic data from block chain
When, the first cryptographic Hash is compared with the second cryptographic Hash.
S104 judges the client when client confirms that first cryptographic Hash is identical as second cryptographic Hash
Hold the shared economic data obtained from the database and the shared economic data stored on the block chain identical.
When the first cryptographic Hash is consistent with the second cryptographic Hash, client determines the number of the shared economy obtained from database
According to be it is safe, be not tampered with, it is consistent to share economic data with this on block chain.
Using the querying method of data on block chain provided in an embodiment of the present invention, by by the shared economy on block chain
Data be resolved in database, then client is obtained from database as needed shares economic data, shortens visitor
Family end obtains the time for sharing the data of economy from block chain, improves client and obtains the efficiency for sharing economic data,
Improve the experience of user.
