Based on above-mentioned implementation environment shown in FIG. 1, the embodiment of the present application provides a kind of notice information exhibition based on block chain Show method, is applied to for first terminal and block catenary system in this way.As shown in Fig. 2, side provided by the embodiments of the present application Method may include steps of:

201, first terminal is based on notice information and shows instruction, sends notice information to block catenary system and shows request, public It accuses information and shows that request carries the identification information of destination application.

First terminal is the terminal for referring to show notice information, can install that there are many using journey in first terminal Sequence, for example, game class application program, communication class application program etc..In the embodiment of the present application, application user currently logged in Program is as destination application.Notice information refers to the open information for informing user, generally by the developer of application program In exploitation, terminal editor is generated, the information such as variation and activity advance notice for being used to indicate in the application program.It is wrapped in notice information Include but be not limited to the information such as bulletin content, timestamp, bulletin title.

Block catenary system is made of multiple node devices, and multiple node device is configured with a plurality of block chain.It needs to illustrate , which can be an application program service, or multiple application program services.When block catenary system When for an application program service, any one block chain in the block catenary system can be used for storing appointing for the application program A kind of business datum for function of anticipating, for example, block chain A is used to store the notice information of the application program, block chain B is for storing Resource transfers data of the application program etc..When block catenary system is multiple application program services, in the block catenary system Different blocks chain can be different application program service, that is to say, that any one block chain in the block catenary system can be with For storing the business datum of any one application program, for example, block chain C is used to store the business datum of application program M, area Block chain D is used to store the business datum etc. of application program N.In the embodiment of the present application, block catenary system can be target application Procedure service, and there is the target block chain for storing the notice information of destination application.

Before first terminal sends notice information displaying request to block catenary system, needs first to obtain notice information displaying and refer to It enables.In a kind of possible implementation, first terminal obtains notice information and shows that the mode of instruction includes but is not limited to following three Kind:

Mode one: when first terminal detects that user's never logging state is converted to logging state, that is, work as user When success logs in destination application, automatic trigger notice information shows instruction, and thus first terminal obtains notice information and shows Instruction.

Mode two: first terminal shows the displaying entrance of notice information in the homepage face of destination application；When detecting When the trigger action of the displaying entrance, first terminal obtains notice information and shows instruction.

Wherein, the form for showing entrance can be button or icon etc..First terminal detects the triggering for showing entrance The case where operation, can be different and different according to the type of first terminal, and the embodiment of the present application is not limited this.Example Such as, first terminal detects that the case where trigger action for showing entrance can be first terminal and detect the pressure touching for showing entrance Control operation is also possible to first terminal and detects the clicking operation etc. for showing entrance.Wherein, clicking operation, which can refer to, passes through mouse The clicking operation carried out is marked, may also mean that the clicking operation etc. carried out in a manner of inputting shortcut key keyboard.

Mode three: presetting the reference time interval for refreshing the notice information shown, every a reference time interval, Notice information of first terminal automatic trigger shows instruction.

Wherein, reference time interval can be rule of thumb arranged, and can also carry out free tune according to the type of application program Whole, the embodiment of the present application is not limited this.For example, reference time interval can be set to 60 seconds.

First terminal sends notice information to block catenary system and shows request after obtaining notice information and showing instruction, The notice information shows that request carries the identification information of destination application.Wherein, the identification information of destination application refers to The information of the unique identification destination application, for example, the exploitation code of the title of destination application, destination application Deng.Since different application programs is corresponding with different notice informations, there may be a plurality of block chain to be used in block catenary system Store the notice information of different application.So first terminal needs the identification information of destination application being sent to block Catenary system, so that block catenary system can determine the target for storing the notice information of the destination application according to the identification information Block chain.

202, the notice information that the first node equipment in block catenary system receives first terminal shows request.

Specifically, the notice information that first node equipment receives first terminal shows that the process of request can be with are as follows: the After one terminal sends notice information displaying request to block catenary system, the management node device in the block catenary system receives this Notice information shows request；Management node device shows the mark letter of the destination application carried in request based on notice information Breath, inquiry whether there is target block chain corresponding with the identification information in block catenary system；If it exists, then by notice information Show that request is sent to the first node equipment configured with the target block chain；First node equipment receives notice information displaying and asks It asks.In the embodiment of the present application, will receive management node device transmission notice information show request node device as First node equipment.

In a kind of possible implementation, management node device shows the target application carried in request based on notice information The identification information of program, inquiry whether there is the mode packet of target block chain corresponding with the identification information in block catenary system It includes but is not limited to following two:

Mode one: management node device traverses all block chains in the block catenary system, until inquire with The corresponding target block chain of the identification information of the destination application until traverses all block chains.

Wherein, when all block chains of traversal do not inquire target corresponding with the identification information of the destination application also When block chain, illustrate that there is no target block chains.

Mode two: being stored with the mapping table of identification information and block chain in the management node device, the management section Point device whether there is target block chain corresponding with the identification information according to mapping table inquiry.

Specifically, the management node device inquires the mark with the presence or absence of the destination application in mapping table Information, when, there are when the identification information of the destination application, illustrating that there are corresponding with the identification information in mapping table Target block chain directly determines target block chain according to the mapping relations in the mapping table at this time；When in mapping table There is no when the identification information of the destination application, illustrate that there is no target block chains.

It should be noted that notice information can be shown that request is sent to one or more first segments by management node device Point device, since each first node equipment is each equipped with target block chain corresponding with identification information, so either which First node equipment receives the notice information and shows request, can show request based on the notice information, execute step 203。

203, the first node equipment in block catenary system is based on identification information, most from the block height on target block chain In the first big block, the notice information and Block Characteristic value that the first block is stored are obtained.

Wherein, target block chain refers to the block chain of the notice information for storing destination application.

First node equipment in block catenary system is configured with a plurality of block chain including target block chain.Cause This, the first node equipment before obtaining the notice information and Block Characteristic value that the first block is stored, in block catenary system It needs first to determine target block chain.

In a kind of possible implementation, first node equipment determines the mode of target block chain are as follows: the first node is set It is standby to be based on identification information, target block chain corresponding with identification information is determined in a plurality of block chain.Specifically, the first segment Point device shows the mark letter that destination application is parsed in request from notice information after obtaining notice information and showing request Breath, then determines target block chain corresponding with the identification information.

In a kind of possible implementation, first node equipment determines the side of target block chain corresponding with the identification information Formula includes but is not limited to following two:

Mode one: first node equipment traverses all block chains of the first node device configuration, until determining Target block chain corresponding with the identification information.

Mode two: the mapping table of identification information and block chain, the first segment are stored in the first node equipment Point device determines target block chain corresponding with the identification information according to the mapping table.

After determining target block chain, the first node equipment is it needs to be determined that be stored with the newest public affairs of destination application The block for accusing information, using the block as the first block.Due to multiple blocks on target block chain be sequentially in time into Row storage, the block height of block is bigger, illustrates the timestamp of the notice information stored in the block closer to current time Stamp, it is possible to using the maximum block of block height on target block chain as the first block.

It should be noted that being stored with the area of notice information He the block for the either block on target block chain Block eigenvalue.Wherein, notice information is used to indicate the information such as variation in the application program and activity advance notice, in notice information Including but not limited to announce the information such as content, timestamp, bulletin title.Block Characteristic value is used to indicate unique mark of the block Know, different blocks has different Block Characteristic values.Block Characteristic value can for the cryptographic Hash of the data in block or its His characteristic value relevant to the data in block.Under normal circumstances, Block Characteristic value shows as a string of character strings, for example, character String is " xdewrowv0wgw9egew0r023#scSFVoglb0230t ".

The first node equipment can obtain the notice information stored in first block and area after determining the first block Block eigenvalue, that is, obtain the Block Characteristic of current newest notice information and the block for storing the newest notice information Value.

It should be noted that before step 203, needing that the notice information of destination application is first stored in target area On block chain.The storing process may comprise steps of:

Step 1: the notice information that the second node equipment in block catenary system receives second terminal updates request, bulletin Information update request carries the identification information and notice information to be updated of destination application.

Second terminal refers to the terminal of the permission with editor's notice information, for example, being logged in opening for destination application Send out the terminal of account.After exploitation account of the developer in second terminal login destination application, new public affairs can be edited Accuse information.After new notice information editor, developer can trigger the publication button on the interface of second terminal.The After two terminals receive the triggering command of publication button, notice information is sent to block catenary system and updates request.

The process that the notice information that second node equipment in block catenary system receives second terminal updates request can be with are as follows: After second terminal sends notice information update request to block catenary system, the management node device in the block catenary system is received It updates and requests to the notice information；Management node device updates the mark of the destination application carried in request based on notice information Know information, inquiry whether there is target block chain corresponding with the identification information in block catenary system；It if it exists, then will bulletin Information update request is sent to the second node equipment configured with the target block chain；Second node equipment receives notice information more New request.In the embodiment of the present application, the notice information for receiving management node device transmission is updated to the node device of request As second node equipment.It should be noted that second node equipment and first node equipment can be identical node device, Or different node devices, the embodiment of the present application are not limited this.

In a kind of possible implementation, second node equipment, can be to public affairs after receiving notice information and updating request It accuses the notice information to be updated that information update request carries to be verified, to guarantee the reliability of notice information to be updated.

In a kind of possible implementation, in order to be verified to notice information to be updated, in block catenary system At least one verifying node device can be set, for verifying to notice information to be updated.In addition, in block catenary system Authentication policy can also be set, which can specify that the quantity for the verifying node device that verifying uses, verification mode, tests Card passes through condition etc..Wherein, verification mode whether can be generated according to preset format to verify notice information to be updated, whether Omit required informations such as bulletin title etc.；The condition of being verified can be verified verifying node device minimum number or The verifying node device that person is verified minimum scale etc. shared in all node devices of block catenary system.Based on above-mentioned Condition, the process that second node equipment verifies notice information to be updated can be such that

Verifying node device of the second node equipment into block catenary system sends notice information to be updated；At least one Node device is verified when receiving notice information to be updated, verifies whether the notice information to be updated meets verifying plan Slightly, message is verified to the return of second node equipment after being verified；Second node equipment receives one or more verifying sections What point device returned is verified message, when what is received is verified message and meets authentication policy, illustrates public affairs to be updated Information Authentication is accused to pass through.For example, it is assumed that authentication policy regulation needs at least five verifying node device to be verified, and need extremely Few 3 verifying node devices are verified, then second node equipment verifies node device to 5 and sends bulletin letter to be updated Breath illustrates that notice information verifying to be updated is logical when receiving when being verified message of at least three verifying node device return It crosses.

In a kind of possible implementation, in order to guarantee that second node equipment sends public affairs to be updated to verifying node device The Information Security during information is accused, sends bulletin letter to be updated to any verifying node device in second node equipment Before breath, second node equipment can first add notice information to be updated according to the public key of any verifying node device It is close, obtained encryption information is then sent to any verifying node device.Any verifying node device receiving plus After confidential information, the encryption information can be decrypted according to private key, obtain notice information to be updated.Such mode can have Effect avoids notice information to be updated from being tampered.

After notice information, which updates the notice information to be updated carried in request, to be verified, step 2 is executed.

Step 2: the second node equipment in block catenary system carries out Authority Verification to second terminal.

By carrying out Authority Verification to second terminal, it can judge whether the second terminal has according to Authority Verification result Edit the permission of the notice information of the destination application.When permission verification result passes through for Authority Verification, illustrate that second is whole Hold the permission with the notice information for editing the destination application；When permission verification result is that Authority Verification does not pass through, say Bright second terminal does not have the permission for the notice information for editing the destination application.

In a kind of possible implementation, notice information updates the identification information that second terminal can also be carried in request, For example, the exploitation account etc. that second terminal logs in.Authority Verification is carried out to second terminal, obtains the mode packet of Authority Verification result It includes but is not limited to following two:

Mode one: the common recognition that second node equipment initiates to carry out second terminal Authority Verification is requested, and block linkwork is based on The common recognition of multiple node devices in system is as a result, obtain Authority Verification result.

Specifically, the realization process of mode one can be divided into four steps: 1, second node equipment from notice information more The identification information of second terminal is parsed in new request；2, second node equipment broadcasts the identification information of second terminal, The common recognition for initiating to carry out the identification information of second terminal Authority Verification namely in block catenary system is requested；3, block linkwork Multiple node devices in system are based on common recognition request operation common recognition algorithm, obtain common recognition result；4, second node equipment is based on Common recognition result obtains Authority Verification result.Specifically, Authority Verification result is tested when result of knowing together is to reach common understanding for permission Card passes through, and illustrates that second terminal has the permission of editor's notice information, at this point, executing step 3；When common recognition result is not reach When common recognition, verification result is that Authority Verification does not pass through, illustrates that second terminal does not have the permission of editor's notice information, at this point, the Two node devices can return to error information to second terminal.

Mode two: second node equipment updates the identification information that second terminal is parsed in request from notice information, calls Authentication service carries out Authority Verification to the identification information of second terminal, obtains Authority Verification result.

Wherein, authentication service can for CA (Certificate Authority, digital certificate authentication center) service or Other services.By taking authentication service is the exploitation account that CA is serviced, the identification information of second terminal is second terminal login as an example, by It is that all exploitation accounts to succeed in registration provide digital certificate in CA service, so being logged in simultaneously when second terminal is based on exploitation account When initiating notice information update request, the number for the exploitation account that second node equipment can call CA service to log in second terminal Word certificate is authenticated, and when certification passes through, the exploitation account identity for showing that second terminal logs in is legal, that is, second terminal Authority Verification result pass through for Authority Verification.

Step 3: when Authority Verification leads to, second node equipment in block catenary system based on notice information to be updated, The third block for storing notice information to be updated is generated, third block is added on target block chain.

It is all in block catenary system after the third block of generation is added on target block chain by second node equipment Target block chain after node device synchronized update configured with the target block chain completes adding for a new block as a result, Add.

In a kind of possible implementation, second node equipment based on notice information to be updated, generate for store to The third block of the notice information of update, comprising: second node equipment generates the default Transaction Information for referring to item number；Based on to more New notice information and the default Transaction Information with reference to item number, generate the third block for storing notice information to be updated. Specifically, judging the type of the Transaction Information after second node equipment receives new Transaction Information；When determining the transaction It is random immediately to generate the default Transaction Information for referring to item number when the type of information is by notice information；It is then based on to be updated The default Transaction Information of notice information and reference item number, can be immediately generated third block.Wherein, default Transaction Information can be Refer to any information generated at random, may also mean that the information of the fixed format generated according to preset format, the application are implemented Example is not limited this.It by the above process, can be immediately when second node equipment receives notice information to be updated The third block for being stored with notice information to be updated is generated, receives sufficient amount of Transaction Information without waiting, without Preset time interval is waited, so as to reduce the delay for storing notice information to be updated, guarantees the real-time of notice information Property.

In a kind of possible implementation, second node equipment can return to notice information to be updated to second terminal Storage result, so that second terminal knows whether notice information to be updated stores success.Specifically, working as second node equipment When successfully generating third block and being successfully added to third block on target block chain, it can be returned to second terminal Storage is successfully as a result, for informing that the newest notice information of second terminal has been successfully stored in target block chain；When second Node device generates third block with failing, and/or when being added to third block on target block chain with failing, Being stored in as a result, being used to inform that the newest notice information of second terminal fails for storage failure can be returned to second terminal On target block chain.

It should be noted that being required to carry out above-mentioned steps one to step 3 when needing to update notice information every time.Target Stored notice information does not allow tampering on block chain, and the addition on target block chain is only allowed to be stored with new notice information Third block.The Block Characteristic value of third block is related to the Block Characteristic value of a upper block, realizes target block chain The purpose that the adjacent block in middle front and back is together in series, so that can be by next to distorting for any information in target block chain The Block Characteristic value stored in a block is traced and is detected.The mode that notice information is stored to target block chain avoids Notice information is lost or is tampered, and ensure that the safety and reliability of notice information, greatly reduces malicious modification public affairs A possibility that information is with user cheating is accused, is conducive to the transparency and degree of belief that promote notice information, is also convenient for subsequently through mesh Mark block chain carries out notice information the operation such as to inquire.
