There is service API (Application Programming Interface, application programming interface), service API can belong to
In shared system 10, it is also possible to the service API of individualism.In the bottom of service API, encapsulate by several block chain nodes
The block chain network of composition, each resource node can be by calling service API to interact with block chain network.Each resource
The shared of resource is realized in the synchronization for carrying out resource between node by resource transport protocol, and each resource node both can be used as
Resources requesting party can also be used as source synchronous side.Wherein, the interface that can integrate multiple and different functions in API is serviced, such as
The establishing resource interface used to store metadata in establishing resource；When verifying resource for obtaining the audit interface of metadata
Deng being not limited to an individual interface.
Wherein, the resource proposed for the embodiment of the present application, including be data resource and file resource two types
Resource.Data resource refers to the resource of type of database, i.e., resource internal record is one or more databases；File
It is one or more any type of files that resource, which refers to inside resource,.Each of shared system resource node all can serve as
Resources requesting party or all sides of resource.
It referring to figure 2., is the inside structure schematic diagram of resource node provided by the embodiments of the present application, a resource node can
To be that perhaps tissue is provided with database (component containing binlog), among database in enterprise or organization internal for an enterprise
Part, file system level of abstraction, distributed document storage service, Peer-web (a kind of communication component), browser.Wherein, it browses
Device can be understood as client, i.e., operating platform used by a user, the browser may be mounted at computer, mobile phone, plate etc.
On electronic equipment.It is the customized component of internal system, function is as whole system about Peer-web component
User's interactive entrance and external interactive entrance, the interaction of user and system all pass through this component and complete.
It can be seen that being abstracted the components such as Peer-web inside resource node, each resource node is allowed to share resource
It does not need to pay additional development cost, the flexible control to resource can be realized.
Wherein, browser is used for user's accessing system, and the creation and request money of resource can be carried out after accessing system
Source.Certainly, user wants accessing system, needs register account number, and the registration information of user can store in the server after register account number,
It is subsequent to can be carried out logging in, to initiate to interact.Since there are two types of the resources of type, so in enterprise or organization internal,
It is provided with database and database middleware resource for storing data；It is provided with file system level of abstraction and distributed document is deposited
Storage service is used for storage file resource.For distributed document storage service, it can be understood as file is carried out distributed deposit

It referring to figure 3., is block chain network structural schematic diagram provided by the embodiments of the present application, several block chain nodes are usual
It is deployed at several trust authorities, forms alliance's chain, each block chain node can save relevant data.Block chain network
Including intelligent contract, account book (Ledger).Transaction record in block chain is rendered as a key-value pair data record, all key assignments
Pair state conversion record constitute the account book of block chain, account book have the characteristics that orderly with it is anti-tamper.State conversion is block
The each block chain node participated in chain network submits chain code (Chaincode) to call the result generated.Each trade fair generates
One group of assets key-value pair, these key-value pairs submit to account book as " creation ", " update " or " deletion ".Chain code
(Chaincode) it is intelligent contract that block chain provides, is to service the medium that interacts with block chain of API.Service API can pass through
SDK (Software Development Kit, software tool development kit) calls chain code (Chaincode) to be handed over account book
Mutually, asset data is written on block chain, or takes out the current state of assets from slip condition database.
Based on the shared system 10, referring to figure 4., it is assumed that resource node 11 is used as resource acquisition side, and resource node 12 is made
For all sides of resource, may include: applied to the resource share method in the shared system 10
Step 100: resource node 12 creates first resource, and the metadata of first resource is stored in block chain network
On.
Step 110: first resource is synchronized to resource node 11 by resource node 12.
Step 120: resource node 11 obtains the synchronous first resource of resource node 12.
Step 130: resource node 11 calls preset audit interface to obtain the first resource being stored in block chain network
Metadata.
Step 140: resource node 11 is according to the correctness of metadata validation first resource.
Pass through the above-mentioned introduction to shared system 10, it can be seen that shared system 10 is the shared knot an of decentralization
Structure does not need the switching plane in center, and each resource node can synchrodata.Resource node in the shared system 10 can
To be verified according to the metadata being stored in block chain network to resource, realizes the auditing possibility of resource, guarantee to get
Resource reliability.
It is resource-sharing side provided by the embodiments of the present application referring to figure 5. for the creation process of resource in step 100
First implementation flow chart of method, as shown in figure 5, the implementing procedure includes:
Step 201: resource node 12 obtains the asset creation request of user.It wherein, include user in asset creation request
The resource to be created of selection and the metadata of resource to be created.
Step 202: resource node 12 stores resource to be created, and the metadata of resource to be created is stored in area
In block chain network.
In the embodiment of the present application, each resource node can be requested according to the asset creation of user, complete the creation of resource,
And the metadata of resource to be created can be also stored in block chain network during creation.Therefore, there are other resources
When node requests the resource, the corresponding metadata of the resource can also be obtained from block chain network, is audited to it, realize
The auditing possibility of resource.
In step 201, the mode that user initiates asset creation request may is that through browser or other clients
Log on to shared system 10, after login, user selects resource to be created by corresponding option, is then filled out money to be created
Then the metadata in source clicks the initiation for the similar option such as submitting or completing complete asset creation request.For metadata,
It may include: the cryptographic Hash of the description of the title, resource of resource, resource, metadata is a kind of for describing the number of data attribute
According to, in the embodiment of the present application, can be used as description Resource Properties data.Certainly, metadata includes, but are not limited to this Shen
Please embodiment proposed, can also be any other data that can be used in resource definition attribute.Wherein, money to be created
Source can be understood as sharable resource.
For resource described in the embodiment of the present application, preamble by the agency of mistake, may include two kinds of resource, because
This, when user selects resource to be created, it is also an option that the type of the resource created.
In step 202, since resource to be created may be file resource or data resource, for difference
The storage mode of resource be also slightly different, it is introduced separately below.
It, can be with if user has selected a listed files when the resource to be created that user selects is file type resource
Directly stored.In shared system 10, it is provided with file abstraction layer interface, file abstraction layer interface is one abstract
SDK (Software Development Kit, software tool development kit).By being abstracted connecing to the operation of file for standard
Mouthful, such as Read, Write, Seek, packaging bottom layer distributed file system is realized.The different distribution text of the docking that can be convenient
Part storage, such as HDFS (Hadoop Distributed File System, distributed file system), BFS (Baidu File
System, Baidu's file system) etc..When needing to replace bottom distributed storage, using file abstraction layer interface, can accomplish
Using unaware.Therefore, resource node 12 can call directly file system abstraction layer interface and file resource is saved in distribution
In formula file storage service.
When the resource to be created that user selects is data resource, such as user's selection is database to be sharing, first
After converting the corresponding file resource of data resource for data resource, then corresponding file resource stored.
For specifically converting and storing process, possible implementation: what it is when user's selection is some database, resource
Node 12 is converted into corresponding file by the binlog message of correspondence database, by database middleware, then is taken out by file
As file is finally saved in distributed storage service by layer interface.Database middleware is an abstract tool assembly, is made
With being the binlog for parsing database, file storage is converted into distributed document storage service by binlog.In addition, data
Library middleware can also parse binlog file from distributed document storage service, restore the data in database.
Regardless of the resource of type, all it is finally to be stored by distributed document storage service, passes through distribution
Formula file storage service storage resource, will be in resource storage to different equipment or host, it is ensured that resource will not lose.
Certainly, in practice, resource to be created can also be carried out to the storage of other modes, such as centralization is deposited
Storage.
In addition to storing good resource to be created, memory node 12 is also by the corresponding metadata storage of resource to block link network
On network, synchronous with storage resource it can will be carried out in metadata to block chain network, it can also be to get request to create laggard
Row, it is not limited here.It may include: that calling establishing resource interface passes through by metadata storage to the process in block chain network
Intelligent contract in block chain network is interacted with the account book in block chain network, metadata to be written on account book.
It is understood that being integrated with multiple functional interfaces in service API, an establishing resource interface can be set and use
It is interacted with block chain network when storing metadata in resource node 12.Since the state of all key-value pairs converts record group
At the account book of block chain, and the conversion of each next state be participated in system each side submit intelligent contract call generate as a result,
Therefore, by calling intelligent contract that data can be written into block chain account book or extracting data.Resource node 12 calls
Establishing resource interface, establishing resource interface recall intelligent contract, call the mode of intelligent contract can be and pass through establishing resource
The SDK installed on interface is called, and after calling successfully, the metadata that user fills in can be written into account book, and then complete
It stores metadata in block chain network.
In addition, each resource can have a unique resource ID (Identification, identity), i.e. identity,
When the metadata of storage resource and storage resource, resource ID can be stored together with resource and resource metadata, it can
For locating resource.Wherein, resource ID can be used as a part of metadata, be also possible to be separately provided and metadata pair
It should store in block chain network.
By storing metadata in block chain account book, block chain account book is used to record the state conversion of key-value pair,
Have the characteristics that it is orderly and anti-tamper, it can be ensured that the metadata being stored on account book will not change, and then being capable of conduct
The foundation of verify data.
After the creation for completing resource, in 11 side of resource node, step 120- step 130 can be executed, in resource node 11
After getting the synchronous first resource of resource node 12, preset audit interface can be called to obtain the corresponding first number of first resource
According to.Compared with prior art, needed for resource node 11 in the prior art can only get oneself by interface or pre-set programs
Resource, can not audit to it, and the resource node 11 of the embodiment of the present application can be according to being stored in block chain network
Metadata first resource is verified, realize the auditing possibility of resource, guarantee the reliability of first resource got.
In the step 120, resource node 11 gets the synchronous first resource of resource node 12.For the first resource,
The resource that can be 11 request of resource node is also possible to the resource of 12 active synchronization of resource node.
The first is possible, if the resource of 11 request of resource node, prior to step 110, this method further include: money
The resource request of the reception user of source node 11；In the not corresponding first resource of resource node 11, asked according to the resource
Resource-sharing is sought survival into request；Resource-sharing request is sent to resource node 12.Resource node 12 is receiving the resource request
First resource is synchronized to resource node 11 again afterwards.As an example it is assumed that Liang Ge enterprise is business partner, Liang Ge enterprise
Client is shared, but, if one of enterprise finds that a client is more high-quality, is thought for different demands for services
It is to be understood that the related data of the client, the data of the client has in another enterprise there just, at this point, the enterprise can be to
Another enterprise proposes the request of the resources sharing of client, and then another enterprise is synchronized to separately by the corresponding method of synchronization again
One enterprise, makes another enterprise also possess the data of the client.
By this possible mode, only when there is corresponding resource request, isochronous resources are just requested, can reduce altogether
The pressure for enjoying resource node improves the efficiency of resource-sharing.
In addition, in order to guarantee the safety of resource-sharing, resource node 12 can also be right in the first possible mode
The request of resource node 11 is verified, and after being verified, just carries out the synchronization of resource, therefore, after initiating request, the party
Method further include: resource node 12 receives the resource-sharing request that resource node 11 is initiated；Resource node 12 is verified resource-sharing and is asked
The legitimacy asked；When it is legal for determining resource-sharing request, first resource corresponding with resource-sharing request is synchronized to money
Source node 11.
Wherein, when verifying the legitimacy of resource-sharing request, possible implementation: pass through verifying resource node 11
The legitimacy of authentication resource-sharing request.For example, it is assumed that the resource-sharing request that A enterprise initiates, B enterprise can verify A enterprise
Whether industry is legitimate enterprise, whether A enterprise is proper enterprise, the similar enterprise etc. such as wrongful enterprise such as hacker's tissue.
After legitimacy by verifying resource-sharing request, corresponding resource is resynchronized, guarantees the safety of resource-sharing,
Situations such as avoiding malice from revealing appearance.
Second possible, although resource node 11 does not request resource, resource node 12 is creating some resource
When, it is believed that resource node 11 may have the demand using the resource, actively by the source synchronous to resource node 11.More than same
It stating for example, one of enterprise finds a more good client, and has collected the related data of the client, due to
The client is more high-quality, which just actively gives the related data synchronous sharing of the client to another enterprise.
By this possible mode, the instant sharing of resource can be realized, also can reduce to a certain extent altogether
The pressure for enjoying node improves the efficiency of resource-sharing.
For resource node 12 by source synchronous to the mode of resource node 11, the embodiment of the present application provides a kind of possible
Implementation: first resource can be synchronized to resource node 11 in confirmation by the owner of the resource node 12 as first resource
Afterwards, representing resource node 11 is the node with first resource permission, and the node with first resource permission can have multiple.?
That is resource node 11 can be added in a channel by resource node 12, channel is a kind of abstract permission isolation
Mode can be mutually synchronized file between the node in the same channel, but only Resource Owner could more new resources text
Part, such as only have resource node 12 that can just update resource file herein.In the same channel, synchronizing for resource is shared,
It is to be diffused into other all nodes outward from Resource Owner, this is a kind of distributed file synchronization protocols, both be ensure that
Efficient file synchronization, and node to be sharing will not be needed excessive because of resource and increase the pressure of Resource Owner's node.
In addition, the mode of isochronous resources is also slightly different based on different resource types.For the resource of file type,
It is stored when storage according to distributed document storage service, so in synchronous documents resource, directly according to above-mentioned file
Synchronous protocol synchronizes.
And for the resource of data type, when storage is first to be converted into file resource according still further to distributed document storage service
It is stored, so in synchrodata resource, after the binlog file synchronization of database is to resource node 11, database
Middleware can automatically parse corresponding document, finally restore data in database.
In step 130, for interface of auditing, it is to be understood that multiple functional interfaces are integrated in service API,
Therefore an audit interface can be separately provided, is handed over when obtaining metadata with block chain network for resource node 11
Mutually.
In step 130, what resource node 11 obtained is that resource node 12 is stored in block chain when creating first resource
A kind of mode of possible acquisition: metadata on network with resource node 12 when creating the resource of itself, stores metadata
Mode it is corresponding.When obtaining, resource node 11 calls preset audit interface, which goes to call block chain network again
In intelligent contract, then call block chain account book to take out the corresponding metadata of first resource by intelligent contract.Obtaining first
When the corresponding metadata of resource, the corresponding metadata of first resource is found according to the resource ID of first resource.
After getting the corresponding metadata of first resource, resource node 11 can execute step 140, carry out testing for resource
Card.The process of verifying may include: that the title of first resource, description and cryptographic Hash are compared with metadata, be compared
To result；The correctness of the first resource is judged according to comparison result.
After getting first resource, the title, description and cryptographic Hash of first resource itself be it is known, can be by it
It is compared with metadata.Such as: the title of file is compared either with or without change, if change, resource may be incorrect；It compares
Whether the description of file changes, such as is the particulars of A client to the description of file originally, is X to the description of file now
The particulars of client, then the resource is incorrect certainly；Or whether the cryptographic Hash of comparison file changes, if changing
Resource is also incorrect certainly.
Whether after obtaining comparison result, it is correct to verify resource, after this authentication, can also be generated according to comparison result
Verification result is fed back to resource node 12 by verification result, and resource node 12 can also be made further anti-according to verification result
Feedback etc..Such as: if the title of file has altered, but the content of file itself is not changed in fact, being can be with
It is used as correct resource, at this point, resource node 12 can make explanations to it, and announcing resource node 11, resource section
The resource can be used in point 11 in turn.But a verifying generally speaking, is carried out to resource, it is ensured that the reliability of resource mentions
The utilization rate of high resource.
It should be noted that either the creation of resource is either shared waits implementing procedures in above-mentioned introduction, it is suitable for altogether
Enjoy any one resource node in system 10, it is assumed for example that resource node 13 is currently wanted to request a money to resource node 11
