Optionally, the transactions requests that the available local of localized nodes is initiated based on the intelligent contract of application.For example, the machine section Point clicks application button event detecting a certain user account on localized nodes, it is determined that there is the user account application to need It asks, localized nodes can give the intelligent contract showing interface of application corresponding to application demand to the user account at this time, later should User account can initiate transactions requests by the intelligent contract interface of the application；And then localized nodes can obtain user account at it The transactions requests that ground is initiated based on the intelligent contract of application.
It is closed due in addition to being deployed with using intelligent contract, being also deployed with basic intelligence in the block catenary system of localized nodes About.In order to carry out area to the transactions requests initiated based on the intelligent contract of application and the transactions requests initiated based on basic intelligent contract Point, further, for example specific identifier of identification information can be added in the transactions requests initiated based on the intelligent contract of application Or intelligent contract title of application etc..
S220 loads the intelligent contract of application for executing transactions requests, and loads at least one and supervise intelligent contract.
In the present embodiment, supervising intelligent contract is supervision account in block chain network based on the basis in block chain network What intelligent contract was disposed, for executing corresponding monitoring function to transactions requests.Wherein supervision account is based on block link network Contract account made of the intelligent contract deployment in basis in network.Optionally, a supervision account can be belonging one or more Supervise unit, that is to say, that at least one supervision account (i.e. one is deployed with by least one supervision unit in block chain network Supervision unit can dispose one or more supervision accounts or multiple supervision units dispose one or more supervision accounts together Family), wherein supervision unit for example can be public security system, network supervision center and yellow anticentre etc..
Optionally, a supervision account can be deployed at least one and supervise intelligent contract, and the intelligent contract of each supervision is used for Execute corresponding monitoring function.It may include at least one of following that intelligent contract is supervised in the present embodiment: real name contract, using intelligence Energy contract closes contract, filtering sensitive words contract, initiates user identity contract and yellow anti-contract.Wherein, real name contract can be used for Whether the initiation account of verifying transactions requests carried out real-name authentication；Closing contract using intelligent contract can be used for transactions requests Whether the intelligent contract of the application called, which is closed, is verified；Filtering sensitive words contract, which can be used to identify in transactions requests, to be carried Sensitive vocabulary and filtered；Initiate user identity contract can be used for the initiation account to transactions requests whether belong to preset it is black List or white list are verified；Yellow anti-contract can be used to identify yellow anti-data (such as yellow picture whether is carried in transactions requests Or text etc.).
In the present embodiment, specific execution logic can be had by supervising in intelligent contract, as filtering sensitive words contract can pass through Code identification sensitive word is filtered；Application can be identified by the blacklist or white list of program by closing contract using intelligent contract Rogue program in intelligent contract is closed.In addition, logic can also not executed specifically by supervising in intelligent contract, that is, hold Capable code is sky, and specific data audit can be executed by supervision unit, can such as send the data to yellow anticentre and carry out Yellow picture and the identification of text etc..
Specifically, localized nodes need to pass through load after obtaining the transactions requests initiated based on the intelligent contract of application The intelligent contract of code form is run, to handle transactions requests.It can load for executing transactions requests Using intelligent contract, and loads at least one and supervise intelligent contract.Optionally, it is closed for executing the application intelligence of transactions requests Intelligent contract loaded in parallel, or sequence load etc. can be about supervised at least one, the present embodiment does not limit this.
S230 is handled transactions requests, using intelligent contract and the intelligent contract of application is supervised to determine transactions requests Pre-execution result.
In the present embodiment, pre-execution result can be understood as localized nodes and be closed using the intelligent contract of supervision and application intelligence About, pre-execution is carried out to the transactions requests based on the intelligent contract of application locally initiated and operates generated result.Optionally, in advance May include in implementing result during calling the intelligent contract of application to execute transactions requests needed for read data (i.e. reading data set), Write-in data (writing data set) needed for transactions requests have executed and the intelligent contract executive condition of supervision；It can also include thing Signing messages needed for needing the resources such as the interface called and the transactions requests to execute in business request implementation procedure such as initiates user The authorized signature etc. of offer.

It should be noted that the intelligent contract of application is usually called to execute transactions requests, the resource for needing to occupy is relatively more, because This improves the treatment effeciency of transactions requests to reduce the data operation quantity of transactions requests treatment process, in the present embodiment At least one of load supervises application intelligent contract of the execution sequence prior to load of intelligent contract, and concrete condition will be following It describes in detail in embodiment.
S240 according to the supervision intelligence contract executive condition in the pre-execution result of transactions requests, and is preset in block The permission control strategy that supervision account belonging to intelligent contract is supervised in chain carries out supervision to the implementation procedure of transactions requests and closes rule Verifying.
Optionally, each supervision account is deployed with corresponding permission by basic intelligent contract and controls data.Wherein, permission Control data may include member account's set and permission control strategy.At least one user's account is stored in member account's set The account address at family, for limiting the user account for having administration authority to supervision account；Preferably, it is deposited in member account's set Storage has the account address of the user account of administration authority.Permission control strategy, which is used to limit, operates plan to the management of supervision account It slightly, is supervision specified when supervising account creation by the founder of supervision account or the owner's customized determination as needed The attribute of account.
Further, the intelligent contract executive condition of different supervision may be provided with different permission control strategies.For example, if Supervising intelligent contract executive condition is to be verified as a result, corresponding, and permission control strategy can appoint to supervise in intelligent contract The verifying of meaning one does not pass through, then does not use and execute transactions requests using intelligent contract.It is if supervising intelligent contract executive condition The called mark of intelligent contract is supervised, corresponding, permission control strategy can be to have finger in the pre-execution result of transactions requests The endorsement signature for determining account, can just call the supervision intelligence contract.
It include supervising intelligent contract executive condition, and then directly parse pre-execution knot in the present embodiment, in pre-execution result Fruit can obtain the intelligent contract executive condition of supervision from pre-execution result；Later can according to supervising intelligent contract executive condition, And the permission control strategy of supervision account belonging to intelligent contract is supervised in block chain, the implementation procedure of transactions requests is supervised Pipe closes the verifying of rule.
For example, if supervise intelligent contract executive condition be verified as a result, if can be obtained according to from pre-execution result Take the intelligent contract of each supervision is verified result；Then determine whether to accord with according to each result that is verified for supervising intelligent contract Permission control strategy is closed, the verifying that rule are closed in supervision is carried out to transactions requests implementation procedure to realize.
It should be noted that intelligent contract is supervised by introducing in the present embodiment, so that the affairs in block chain network are asked The verifying being required to by supervising the permission control strategy of supervision account belonging to intelligent contract is asked, and then realizes supervision unit pair Effective supervision of data in block chain.
S250 closes the verification result of rule according to supervision, determines the validity of transactions requests pre-execution result.
In the present embodiment, if the verification result that rule are closed in supervision is to pass through, it can determine that transactions requests pre-execution result has Effect；If the verification result that rule are closed in supervision is that verifying does not pass through, it can determine that transactions requests pre-execution result is invalid.
The authenticity and/or validity of transactions requests are tested for the ease of other block chain nodes in block chain network It demonstrate,proves, can also include: that pre-execution result is encapsulated into transactions requests after the validity for determining the transactions requests implementing result In, it is transmitted into block chain network, to request other block chain node verification transactions requests.
Specifically, pre-execution result can be encapsulated into affairs after localized nodes determine the validity of transactions requests and asked In asking, and it is transmitted to block chain network.After other block chain nodes in block chain network receive transactions requests, can first it adopt The verifying that rule are closed in supervision is carried out with implementation procedure of the S240 to transactions requests, then calls the intelligent contract of application to execute affairs and asks It asks, to obtain verifying implementing result, and is matched with the pre-execution result in acquired transactions requests；Further, may be used With by verify implementing result in reading data set and write data set, respectively and in the pre-execution result in acquired transactions requests Reading data set and write data set and matched；If successful match, it is determined that transactions requests pre-execution result is effective；Later, may be used It stores pre-execution result as Transaction Information into block.
Further, other block chain nodes for getting the transactions requests including pre-execution result, which can default the affairs, asks The verification result that rule are closed in the supervision for the initiation node asked is to pass through, and then can directly carry out above-mentioned to the authenticated of pre-execution result Journey.
Optionally, if localized nodes are that current block generates node, after the validity for determining transactions requests implementing result, Transactions requests including pre-execution result can also be stored as Transaction Information into block；It later can be by the encrypted communication To block chain network, to request other block chain node verifications to store.
Technical solution provided in an embodiment of the present invention, by using the intelligent contract of the application for executing transactions requests and introducing Intelligent contract is supervised, pre-execution is carried out to the transactions requests initiated based on the intelligent contract of application；And according in pre-execution result Intelligent contract executive condition, and the permission control strategy of supervision account are supervised, the implementation procedure of transactions requests is supervised The verifying of rule is closed, to realize the verifying to the validity of transactions requests pre-execution result.This programme is by introducing supervision intelligence Contract, so that the transactions requests in block chain network are required to supervise the Authority Verification of account belonging to intelligent contract by supervising, It is realized with this and data in block chain is effectively supervised.

S340, the intelligent contract executive condition of the supervision obtained from pre-execution result are the called mark for supervising intelligent contract Will executes verification result.
In the present embodiment, for supervising intelligent contract without such as yellow anti-contract of the specific supervision intelligence contract for executing logic Executive condition can be the called mark of the intelligent contract of supervision.Optionally, called mark, which can be, shows the anti-contract of the Huang The mark being called.For will be recorded in pre-execution result to the processing result of transactions requests, unit pair is supervised with request The supervision intelligence contract that processing result is verified, such as filtering sensitive words contract, supervising intelligent contract executive condition can be with To execute verification result.
S350 verifies affairs according to the permission control strategy for supervising account belonging to intelligent contract is supervised in preset block chain The implementation procedure of request is to the calling for supervising intelligent contract or calls whether the execution verification result generated meets permission control plan Slightly.
Illustratively, permission control strategy may include it is following at least one: 1) threshold strategies, for according to the authentication is passed The sum of the weighted value of member account determine whole the authentication is passed result with setting by the relationship between threshold value, wherein at The weighted value of each member account is when defining member's account aggregation in member's account aggregation, by the founder or the owner of supervision account It is allocated；2) endorsement strategy determines whole the authentication is passed knot for the quantity or ratio according to the member account that the authentication is passed Fruit；3) fixed account strategy determines whole for the relationship between the interlock account and default fixed account according to account operation Result that the authentication is passed.Wherein presetting fixed account can be one or more accounts in preassigned member account set；It closes Joining account can be to preset the derivative account of fixed account or by derivative account in member account's set；Further, it presets solid The derivative account for determining account can be understood as the sub- account of default fixed account, inherit at least partly behaviour for having default fixed account Make permission；The parent account that can be understood as default fixed account by derivative account of default fixed account, preset fixed account after It holds by at least partly operating right of derivative account.
In the present embodiment, during the intelligent contract of application executes transactions requests, user account can request other use Family account verify to pre-execution result and feedback signature is endorsed, and obtained signature is added to the setting word of transactions requests Duan Zhong.
Illustratively, it according to the permission control strategy for supervising account belonging to intelligent contract is supervised in preset block chain, verifies The implementation procedure of transactions requests is to the calling for supervising intelligent contract or calls whether the execution verification result generated meets the power Limit control strategy may is that if permission control strategy is fixed account strategy, obtain from the pre-execution result of transactions requests Take the title of signature endorsement account；Determine whether to meet fixed account strategy according to the title of signature endorsement account, to verify thing The implementation procedure requested of being engaged in is to the calling for supervising intelligent contract or calls whether the execution verification result generated meets permission control Strategy；Wherein, signature endorsement account be during the pre-execution of transactions requests be requested pre-execution result is verified after And the account of feedback signature endorsement.
Specifically, can be the title for obtaining signature endorsement account from the pre-execution result of transactions requests, and will acquire Each signature endorsement account title gather with member account in the title of default fixed account match；If matching at Function, it is determined that the implementation procedure of transactions requests is to the calling for supervising intelligent contract or the execution verification result generated is called to meet power Limit control strategy；Otherwise permission control strategy is not met.
Or can also be the title that signature endorsement account is obtained from the pre-execution result of transactions requests, and will acquire The title of each signature endorsement account is matched with the title of the interlock account of the default fixed account in member account's set；If Successful match, it is determined that the implementation procedure of transactions requests is to the calling for supervising intelligent contract or calls the execution verification result generated Meet permission control strategy；Otherwise permission control strategy is not met.
Optionally, according to the permission control strategy for supervising account belonging to intelligent contract is supervised in preset block chain, thing is verified The implementation procedure requested of being engaged in is to the calling for supervising intelligent contract or calls whether the execution verification result generated meets permission control If strategy may also is that permission control strategy is threshold strategies, signature back is obtained from the pre-execution result of transactions requests The title of book account, the title of each signature endorsement account and the title of the member account in member account's set that will acquire carry out Search matching；Determine the sum of the weighted value of each signature endorsement account of successful match；If the sum of weighted value, which is greater than setting, passes through threshold Value, it is determined that the implementation procedure of transactions requests is to the calling for supervising intelligent contract or the execution verification result generated is called to meet power Limit control strategy；Otherwise permission control strategy is not met.
Illustratively, it according to the permission control strategy for supervising account belonging to intelligent contract is supervised in preset block chain, verifies The implementation procedure of transactions requests is to the calling for supervising intelligent contract or calls whether the execution verification result generated meets the power Limit control strategy may also is that if permission control strategy is endorsement strategy, obtain from the pre-execution result of transactions requests The title of signature endorsement account, the title for each signature endorsement account that will acquire and the name of the member account in member account's set Title carries out lookup matching；Determine the quantity or ratio of each signature endorsement account；If the number of each signature endorsement account of successful match The ratio that amount is greater than each signature endorsement account of setting amount threshold or successful match is greater than setting ratio threshold value, it is determined that The implementation procedure of transactions requests is to the calling for supervising intelligent contract or the execution verification result generated is called to meet permission control plan Slightly；Otherwise permission control strategy is not met.
It should be noted that being to supervise called mark or the execution of intelligent contract for supervising intelligent contract executive condition The supervision intelligence contract of verification result is needed such as without the specific anti-contract of Huang for executing logic by the intelligent contract of mandatory requirement application Obtain the signature endorsement of destiny account, also will complex verification process to transactions requests turn by destiny account such as Huang Fanzhong The heart also can avoid the intelligent contract code band of adjustment supervision and come while can be achieved effectively to supervise data in block chain Troublesome operation.
S360, if meeting permission control strategy, it is determined that the verification result that rule are closed in supervision is to pass through.
S370 closes the verification result of rule according to supervision, determines the validity of transactions requests pre-execution result.
