With reference to Fig. 2, Fig. 2 is the flow diagram of block chain trust data management method first embodiment of the present invention.

In the present embodiment, the embodiment of block chain trust data management method is provided, it should be noted that although Logical order is shown in flow chart, but in some cases, it can perform shown with the sequence being different from herein or retouch The step of stating.

In the present embodiment, block chain trust data management method is optional is applied in block chain network, in block link network Trust data provider, block chain operator and block catenary system are provided in network, block catenary system includes trust data management Center.Trust data provider is used to obtain the outer data of chain of the outer data providing of chain, and by data register outside chain to credible number According in administrative center, become trust data.

The outer data providing of chain be in the various systems outside block chain network collect and the mechanism of the outer data of generation chain or Independent individual.It such as weather data, is collected, periodically issued daily one or many by weather bureau.Exchange rate data by appointed bank or Exchange rate management organization generates, and timing daily is issued.The outer data providing of chain is by data publication to given server, for block chain Trust data provider inquires on network.Wherein, mechanism is to be added to the member of independent work in block chain network, and mechanism possesses Certain assets and the user group of oneself.In the scene of transaction in assets, there are two types of the mechanisms of role：It issuer and sells on a commission basis Mechanism.Issuer possesses issuing asset permission, can create and issue the assets of certain share in block catenary system.The power of selling on a commission basis Mechanism is limited, after reaching commercial agreement with issuer, self-administered user assets can be sold to, oneself can also be acted on behalf of User, assets are transferred into his mechanism.

The outer data of chain refer to non-block catenary system and generate in itself, but transaction needs the number used on the chain of block catenary system According to such as weather data, exchange rate data, stock quotations, regional population's number etc., these data pass through non-chain by data providing outside chain What the mode of upper operation was collected and was generated.The essential information of the outer data of one chain include version number, the effective date, the Expiration Date, Identity, public key information, data signature, data source access address, data volume, data format definition and data mode.Wherein, Effective date and Expiration Date are accurate to the time of Millisecond, and using UTC, (Coordinated Universal Time coordinate Universal time) coordinated universal time format, data providing should set time operation to chain with authoritative clock service outside.Identity is one section UUID (Universally Unique Identifier, Universally Unique Identifier) may be used in the identifier that will not be repeated Technology generates, and the byte serial of designated length is converted by HASH (hash) algorithm.Public key information follows PKI (Public Key Infrastructure, Public Key Infrastructure) system, pass through the public key portion for the key pair that rivest, shamir, adelman generates.Number It is to be signed using the private key of data providing outside chain to data outside chain according to signature, trust data must include data signature, What trust data included be in addition to signature in itself other than other all fields.Data source access address is URI (Uniform Resource Identifier, uniform resource identifier) form character string, for identifying the source of data outside chain, to be optional Field can leave blank.Data volume is the data volume of one section of variable length, may include complicated data structure, and form is defined by form Description.Data format definition is the description of json forms, and each data field represents field meanings with name, expressed with type Its type, type definition include the fundamental types such as string, uint256, can include array, but do not include this complexity of map Data structure.In the embodiment of the present invention form description can corresponding data volume be [" demouser ", 100].Data mode Including several states such as True (true), false (mistake), unknown (uncertain)

Trust data provider will obtain the outer data of chain, need through data source outside chain.The outer data source of chain is by data outside chain Provider safeguards, for preserving and safeguarding the logic unit of data outside one or more chains.The outer data source of chain provides connecing for URI Mouthful, pass through http (Hyper Text Transfer Protocol, hypertext transfer protocol), https (Hyper Text Transfer Protocol over Secure Socket Layer, procotol), the network interfaces such as socket externally provide Data query service.The write-in of the outer data source of chain is realized that the outer data source of chain does not provide data outside chain by data providing outside chain Other users except square and its partner disclose the interface of write-in.It can inquire whether data outside chain prolong by data source outside chain When, whether can use etc..

Trust data is to obtain data outside chain by trust data provider, and data outside chain are written to block catenary system On chain, and by a series of verification and format conversion flow, by block, catenary system participant thinks data outside believable chain.It can The essential information of letter data and the outer data of chain are essentially identical, and relative to data outside chain, trust data further includes come into force block height, failure Block is high.Wherein, the block height that comes into force can be just come into force in some block high (high containing the block) of block chain.Optionally, come into force block Gao Mo Recognize the block height where data to come into force at once.Fail block height is when block chain growth is high to some block, that is, is failed.It is optional Ground is defaulted as forever effectively.When block catenary system will be controlled using block height as timeliness, it should set and come into force and fail block It is high.

Trust data source is the logic unit for safeguarding and preserving trust data on block catenary system, can include one A to arrive multiple trust datas, by trust data, provider safeguards.According to the characteristics of block catenary system, trust data source can be one A address.Block catenary system announces away the address in trust data source and relevant queried access method, block catenary system In other participants can pass through the address and access trust data source.Trust data source is only capable of being provided by the trust data formulated Other participants are only provided query interface by side's write-in.The essential information in trust data source includes at least：Identify title, address (dynamic generation during registration), affiliated data providing (using the address mark on block chain), digital signature, credit score, registration Time (UTC length of a game), data access interface definition etc..Wherein, mark title should be unique in block catenary system.

Trust data administrative center is the module that block catenary system is pre-set, and is equivalent to trust data provider and can The bulletin board in letter data source, the trust data provider of new registration and trust data source can all be published to trust data administrative center In, specific announcement trust data provider and trust data source correspond to title, address, state, data access interface definition etc., and The interfaces such as registration, inquiry, modification state, the revocation in trust data source are provided.Block chain operator can by creating interface registration Letter data provider, trust data provider by registration interface register trust data source or change data source state or Cancel data source when not needing to safeguard data source, the participant on block catenary system can by inquiring corresponding interface polls Then the information in letter data source obtains data by the data access interface of trust data source provider.

Trust data provider refers to that the participant for block catenary system provides the mechanism or independent a of trust data service Body.Trust data provider can be with data providing outside chain same mechanism or individual or mutually it is independent.It can Letter data provider possesses the address on block chain, and knows the data service address of the outer data providing of chain, and trust data carries Periodically (such as per minute, per hour, daily etc., different according to the term of validity length of data and set) provides supplier to data outside chain Side goes to obtain the outer data of chain, data outside chain is carried out with basic validity check, including data format, data validity interval, data The verifications such as state by the trust data source of data write-in block catenary system outside effective chain, become trust data, for block chain The participant inquiry of system obtains.One trust data provider can possess and manage one to multiple trust data sources, to carry For different types of data service.The essential information of trust data provider includes：Mechanism or individual title and description, CA are public Key certificate or public key information, the data service range provided, contact person, contact method can register most trust data sources Quantity has the quantity in trust data source, credit score, cash pledge remaining sum etc..

Block chain operator is responsible for auditing, modification, deletes node and account number related data on block chain, such as sets certain The information of one alliance's chain and initialization deployment is carried out, each mechanism is organized to coalize chain, corresponding mechanism is distributed for each mechanism Administrator and deal maker's permission manage life cycle applied on block chain etc..Wherein, node refers in particular to participate in block chain network In, it is traded the network node with data exchange, each independent agency can gather around that there are one to multiple transaction nodes, Mei Gejiao Easy node is one group of physical network, computer, the combination of block chain application software and database.

Block chain monitoring party is additionally provided in block chain network, block chain monitoring party examines all business numbers of block chain network According to, the operating status of supervision and management alliance chain, the legitimate, stable and sound operation of safeguard service.Block chain monitoring party can participate in block The operation of chain sends out instruction to block chain operator, so that block chain operator performs corresponding operating according to instruction.

The block chain trust data management method includes：

Step S10, the audit request audit institute sent by the block chain operator according to the trust data provider State the pending data of trust data provider.

After trust data provider gets data outside the chain of data providing outside chain by data source outside chain, credible number Audit request is sent to giving block chain operator according to provider.When block chain operator receives trust data provider transmission During audit request, block chain operator receives the pending data that trust data provider sends, and audits the pending data. Wherein, pending data includes but not limited to the business license of trust data provider, the authenticity of identity and the fund of registration Etc. information.Specifically, block chain operator can by industrial and commercial bureau inquire trust data provider business license and identity whether Really, situations such as registered capital is with the presence or absence of falseness.When block chain operator confirms that pending data is all correct, then confirm and treat Audit data verification passes through.If block chain operator confirms pending data, there are mistakes, confirm pending data verification not Pass through, terminate auditing flow.

Step S20, if confirming, the pending data verification passes through, and the credible number is authorized by the block chain operator The administration authority in trust data source is managed according to provider, and the trust data provider is registered to the trust data management In center.

When confirm pending data verification by after, block chain operator authorizes trust data provider and manages trust data The administration authority in source, and trust data provider is registered in trust data administrative center.

Further, step S20 includes：

Step a, if confirming, the pending data verification passes through, the block linkwork as described in block chain operation direction System initiates to create the transaction request of the trust data provider, and authorizes the trust data provider and manage trust data source Administration authority, wherein, the transaction data of the trust data provider is carried in the transaction request.

When confirm pending data verification by after, block chain operator authorizes trust data provider and manages trust data The administration authority in source, and to the transaction request of block catenary system initiation establishment trust data provider, wherein, in the transaction request The transaction data of trust data provider is carried, what which included but be not limited to trust data provider provides number According to data format, data signature and data validity interval etc..

Step b receives the transaction request, and whether detect the transaction request by the area by the block catenary system What block chain operator was sent.

After block catenary system receives the transaction request, block catenary system detects whether the transaction request is transported by block chain What battalion side was sent.Specifically, which is to use its private key encryption by block chain operator.If block catenary system can be used The public key decryptions transaction request that the block chain operator that obtains in advance is sent, then confirming the transaction request is runed by block chain Just send.If block catenary system is unable to the successful decryption transaction request, it is not block chain operator to confirm the transaction request It sends.Further, when transaction request is not that block chain operator is sent, block catenary system then refuses trust data offer Side is registered in trust data administrative center, is registered in trust data administrative center to avoid by illegal data providing.

Whether step c if the transaction request is sent by the block chain operator, detects the transaction data Meet preset condition.

After confirming transaction request is sent by block chain operator, it is pre- whether block catenary system detection transaction data meets If condition.I.e. completely whether the data format of detection trust data provider's data, whether correct and data are data signature It is no interior etc. in the term of validity.Specifically, the data format of trust data provider and the data format pre-set are carried out Comparison, when the data format of trust data provider is consistent with the data format pre-set, then confirms that data format is complete It is whole, otherwise, then confirm that data format is imperfect；When the public key that block catenary system is stored by it can successfully parse data signature When, confirm that data signature is correct, otherwise, then confirm data signature mistake；If current time is more than or equal to the effective date, small In the Expiration Date, then confirm that the data of trust data provider are effective, otherwise, then confirm the data of trust data provider without Effect.It is understood that when the data format of trust data provider's data is complete, data signature is correctly and in the term of validity When interior, confirm that transaction data meets preset condition；When the data format of trust data provider's data is imperfect, data signature not When correctly and/or within the failure period, confirm that transaction data does not meet preset condition.

Step d, if the transaction data meets preset condition, by block chain operator by the trust data provider It is registered in the trust data administrative center.

After confirming that transaction data meets preset condition, block catenary system sends prompting message and informs block chain operator, Transaction data meets preset condition.At this point, trust data provider is registered to trust data administrative center by block chain operator.

Further, after trust data provider is registered to trust data administrative center, block catenary system will be credible Data providing is broadcast in block chain network, and clothes can be provided with the participant authentic providing party informed in block chain network It is engaged in.Wherein, participant includes but not limited to block chain operator, block chain monitoring party and other trust data providers.

Further, after transaction data meets preset condition, whether block catenary system detection trust data provider Registration.Specifically, can detect trust data administrative center with the presence or absence of the title of trust data provider, CA public key certificate or Public key information judges whether trust data provider has been registered.If existing trust data carries in trust data administrative center Title, CA public key certificate or the public key information of supplier, then confirm that trust data provider is registered；If in trust data management The not title there are trust data provider, CA public key certificate or public key information in the heart, then confirm trust data provider not Registration.If trust data provider is registered, block catenary system forbids block chain operator to register trust data provider Into trust data administrative center, to avoid trust data provider's repeated registration.If trust data provider is unregistered, area Block catenary system then allows block chain operator that trust data provider is registered in trust data administrative center.

Step S30, after the trust data provider is successfully registered to the trust data administrative center, by it is described can Letter data provider triggers the registration request in registration trust data source, by the trust data Login to the trust data pipe Reason center, so that the participant in the block chain network obtains the trust data source by the trust data administrative center Corresponding trust data.

After trust data provider is successfully registered to trust data administrative center, trust data provider is as a reality Body role is linked into block chain network, and trust data provider triggers the registration request in registration trust data source, by credible number According in Login to trust data administrative center, so that the participant in block chain network is obtained by trust data administrative center The corresponding trust data in trust data source.It should be noted that a trust data provider can correspond to multiple trust data sources, One trust data source can also correspond to multiple trust datas.Wherein, trust data be by trust data provider outside chain data It is obtained in provider.

Further, step S30 includes：

Step e, after the trust data provider is successfully registered to the trust data administrative center, by described credible The registration request in data providing triggering registration trust data source.

Step f, can as described in the block catenary system detection after block catenary system detects the registration request Letter data provider is with the presence or absence of the registration permission in registration trust data source.

After trust data provider is successfully registered to trust data administrative center, trust data provider triggers registration can The registration request in letter data source, and the registration request is broadcasted in block chain network, wherein, registration request carries trust data source Essential information.After block catenary system receives the broadcast corresponding registration request, block catenary system detects the registration request Corresponding trust data provider is with the presence or absence of the registration permission in registration trust data source.In the present embodiment, if trust data Provider has the administration authority in management trust data source, then it is assumed that trust data provider has registration permission；It is if credible Data providing does not have the administration authority in management trust data source, then it is assumed that trust data provider does not have registration permission.

It further, can there are corresponding permissions when trust data source provider is there are during administration authority, in registration request Mark, block catenary system can detect that trust data provider with the presence or absence of note according to whether registration request carries capability identification The registration permission in volume trust data source.

Step g if the trust data provider has registration permission, detects the information in trust data source to be registered Whether preset condition is met.

If confirming there is registration permission in trust data provider, and block catenary system detects trust data source to be registered Whether information meets preset condition.Specifically, whether the essential information for detecting trust data source to be registered meets preset condition, Whether the mark title for such as detecting trust data source is globally unique, you can the mark title in letter data source is in block chain network It is no unique；Whether the digital signature for detecting trust data source effective, that is, detect trust data source data signature whether with it is credible The data signature of data providing corresponds to；Detect registion time it is whether effective and trust data provider is registered can Whether letter data source quantity has been more than or equal to preset quantity etc., and preset quantity can be set according to specific needs, herein not It is limited.When the mark title in trust data source is globally unique, the data signature in trust data source and trust data provider Data signature is corresponding, registion time is effective and the registered trust data source quantity of trust data provider is less than present count Amount, then confirm that the information in trust data source to be registered meets preset condition；Otherwise, then confirm trust data source to be registered Information does not meet preset condition.

Further, whether in effective procedure, the term of validity of registion time has been pre-set, such as in detection registion time Can be set as the term of validity of registion time cannot be one hour earlier than current time, and cannot be later than current time 5 minutes.Work as note The volume time earlier than current time one hour or when being later than current time 5 minutes, then confirms that registion time is invalid, otherwise, confirms Registion time is effective.

If the information in the trust data source meets preset condition, institute is called by the trust data provider by step h The registration interface of trust data administrative center is stated, it will be in the trust data Login to the trust data administrative center.

If the information in trust data source meets preset condition, trust data provider calls trust data administrative center pre- If registration interface, will be in trust data Login to trust data administrative center.When by trust data Login to credible number After administrative center, the participant in block chain network can know registered trust data by trust data administrative center Source obtains trust data by the trust data source.

Further, after trust data Login is to trust data administrative center, trust data administrative center will be credible The value of the corresponding counter of data providing adds one.The counter is for recording trust data provider in trust data management The quantity in trust data source registered in center.

Further, if the information in trust data source does not meet preset condition, terminate trust data Login to can The operating process of letter data administrative center.Further, after the register flow path for terminating registration trust data source, block catenary system The registration operation in the trust data source is recorded, to avoid the follow-up repeated registration trust data source.
