The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the invention.
Summary of The Invention
The inventor finds that in the prior art, no scheme for managing the intelligent contracts on the block chain is provided, so that the user is not facilitated to know the maintenance and operation conditions of the intelligent contracts on the block chain, and the development of the block chain is hindered to a certain extent.
Based on the above, the basic idea of the invention is: the intelligent contracts on the block chains are classified, and the type of the intelligent contracts can be determined by utilizing the interfaces of the intelligent contracts. And on the basis of determining the type of the intelligent contract, managing all aspects of the intelligent contract according to the classification result.
Having described the general principles of the invention, various non-limiting embodiments of the invention are described in detail below.
Exemplary method
An intelligent contract processing method according to an exemplary embodiment of the present invention is described below with reference to fig. 1.
FIG. 1 schematically illustrates a flow diagram of a method for intelligent contract processing according to an exemplary embodiment of the invention. Referring to fig. 1, an intelligent contract processing method according to an exemplary embodiment of the present invention may include the steps of:
and S10, determining interface information of the target intelligent contract.
The target intelligent contract may be any one of a plurality of intelligent contracts that are applied to a blockchain. In addition, when the type of an intelligent contract needs to be determined, the intelligent contract can also be determined as a target intelligent contract. It should be noted that the invention is not limited to any particular type of blockchain, and the blockchain mentioned in the invention may be a public chain, a private chain, or a federation chain.
The interface of the intelligent contract is used for realizing the rule of contract subscription, and the interface information can include but is not limited to interface names, the interpretation of the input and return values of the interface, and the like. In one embodiment of the present invention, the above-mentioned interface information may be characterized by an interface name. For example, the function of the interface may be to transfer an amount w from account a to account B, the interface name being defined, for example, "transfer", i.e. the interface information of the interface may be "transfer".
Intelligent contracts often have multiple interfaces, each interface information being typically in a separate state from the code of the intelligent contract. Therefore, an interface information list of the intelligent contract can be constructed, and the interface information list comprises information of all interfaces of the intelligent contract. That is, the intelligent contracts may establish a mapping relationship with the interface information lists, and one intelligent contract corresponds to one interface information list.
According to some embodiments of the invention, the server may determine a plurality of interface information for the target intelligent contract.
According to other embodiments of the present invention, weights may be configured for each interface of the target intelligent contract in advance, and the server may determine interface information corresponding to an interface with the highest weight in the target intelligent contract as the interface information of the target intelligent contract.
And S14, determining label information corresponding to the interface information of the target intelligent contract.
In an exemplary embodiment of the present invention, the tag information may be used to characterize a type of the smart contract, where the type of the smart contract may include, for example, a token class, a lottery class, a credit class, and the like. That is, different types of corresponding tag information are different.
According to some embodiments of the present invention, first, a preset mapping relationship between the interface information and the tag information may be pre-constructed, and the preset mapping relationship may be stored in the server in a table form or in a storage unit outside the server. Next, the server may determine, according to the preset mapping relationship, tag information corresponding to the interface information of the target intelligent contract.
According to other embodiments of the invention, for a scenario in which some features in the interface information are utilized to determine the tag information, a machine learning method may be adopted to determine the tag information corresponding to the interface information of the target intelligent contract.
Specifically, first, a plurality of interface information may be determined, and a developer may manually determine the label information corresponding to the interface information, and determine the plurality of interface information and the corresponding label information as the training sample. In addition, a developer can construct a machine learning model according to the specific requirements of the intelligent contract, for example, the machine learning model can be a convolutional neural network model, and the number, the dimensionality and the weight of convolutional layers in the convolutional neural network model are not particularly limited in the embodiment of the invention.
Next, the constructed machine learning model may be trained using the training samples to obtain a trained machine learning model. In addition, similar to the process of selecting training samples, a validation set may be determined to validate the trained machine learning model.
Subsequently, the server may input the interface information of the target intelligent contract into the trained machine learning model, and determine the output result of the machine learning model as the tag information corresponding to the interface information of the target intelligent contract.
And S16, adding the label information into the target intelligent contract so as to determine the type of the target intelligent contract according to the label information.
In an exemplary embodiment of the invention, a target intelligent contract is configured with classification attributes. After determining the tag information, the server may write the tag information into the contract classification attribute of the target smart contract.
In the case that the type of the target intelligent contract needs to be determined, firstly, the server may obtain a classified query request of the target intelligent contract through a query interface of the target intelligent contract, where the classified query request may be sent by a user through a terminal device (e.g., a mobile phone, a tablet, a personal computer, etc.); next, the server may determine a type of the target smart contract from the classification attributes based on the classification query request.
The classification process of the intelligent contracts provided by the present invention is described above in an exemplary manner. The classification process of the intelligent contract may be performed on the blockchain, that is, after the target intelligent contract is deployed on the blockchain, the target intelligent contract is classified. However, it should be noted that, when the target intelligent contract is not yet deployed in the blockchain, the classification process of the target intelligent contract may also be performed, that is, after the tag information is added to the target intelligent contract, the target intelligent contract may be uploaded to the blockchain.
The method and the device can effectively realize the classification of the intelligent contract, and further help to manage the intelligent contract based on the classification result. The following describes schemes for performing various management on the smart contracts based on the results of the classification.
Exemplary embodiments of the present invention provide a scheme for liveness management of smart contracts.
First, the server may determine the type of the target intelligent contract as the target type, and determine the intelligent contract with the type on the blockchain as the target type. For example, the determined target type is a token class, and the server may determine the types of all intelligent contracts on the blockchain, and determine intelligent contracts of the token class, where the intelligent contracts on the blockchain include, for example, a target intelligent contract, an intelligent contract 1, an intelligent contract 2, an intelligent contract 3, and the like.
Next, the server may determine the liveness of the smart contract of the type targeted. Specifically, in a preset time period, the transaction amount of the intelligent contract with the target type is counted, and the activity of the intelligent contract with the target type is determined according to the transaction amount. Here, the preset time period may be configured to be 24 hours, however, it is easily understood that the preset time period may be configured based on the historical transaction amount, and the preset time period is not particularly limited in the present exemplary embodiment.
FIG. 2 schematically illustrates a schematic diagram of a transaction amount for a target smart contract. In the example shown in fig. 2, it is known that the preset time period is configured to be 24 hours.
After determining the activity of the intelligent contract of the target type, the server can determine whether to provide investment suggestions for the user according to the activity. Specifically, the server may determine whether the liveness meets a preset requirement, and recommend a project corresponding to the intelligent contract to the user if the liveness meets the preset requirement, where the user may be a user registered on the block chain investment platform. In addition, the preset requirement described herein may be, for example, ten thousand daily activity, and in the example of the activity being characterized by the transaction amount, the transaction amount of the target intelligent contract shown in fig. 2 for five days is only one day that does not satisfy the preset requirement, and based on the result, the investment advice of the item corresponding to the target intelligent contract may be recommended to the user in the respective manners of 2018-11-27, 2018-11-29, 2018-11-30 and 2018-12-01, wherein the investment advice is advice for recommending purchase, and further, the investment advice may further include information such as item introduction and advice reason.
In addition, after determining the activity of the target intelligent contract, if the first preset event occurs, the server may disclose the activity of the target intelligent contract. That is, the first predetermined event may be used as a condition for determining whether the activity is disclosed or not. Specifically, the first preset event may include any one of a state that the item is in a financing state, a state that the item is in a public measurement state, and a state that the item is in a charging state, it is easily understood that the first preset event may further include a transition period that the item is in a transition from an internal measurement to a public measurement, a transition period that the item is in a transition from a non-charging state to a charging state, and the like, and the first preset event is not particularly limited in this exemplary embodiment.
In addition, after the activity of the intelligent contracts of which the types are the target types on the block chain is determined, the intelligent contracts can be sequenced according to the activity, and sequencing results are sent to the user for the user to refer.
Exemplary embodiments of the present invention also provide a solution to the disclosure of intelligent contract source code.
The server may determine whether the type of the target intelligent contract is a first preset type, where the first preset type may be a type that is determined by statistics and is concerned by a user, or a type that is helpful for project development after a source code is disclosed and preset by a developer, and the first preset type is not particularly limited in this exemplary embodiment.
And under the condition that the type of the target intelligent contract is judged to be a first preset type, if a second preset event occurs, disclosing the source code of the target intelligent contract. Similarly, the second preset event may include any one of the condition that the item is in a financing state, the condition that the item is in a public measurement state, and the condition that the item is in a charging state, it is easily understood that the second preset event may also include a transition period that the item is in a transition from an internal measurement state to a public measurement state, a transition period that the item is in a transition from a non-charging state to a charging state, and the like, and the second preset event is not particularly limited in this exemplary embodiment.
The source code of the above-described public target intelligent contract may refer to a fully open source, that is, a public source address, and a source code digest hash value, which is used to verify that the source code is complete and unmodified. In this case, the user can read the relevant information of the contract open source through the query interface.
In addition, the scheme disclosed for the intelligent contract source code can also comprise two cases of delaying the source opening and not opening. Specifically, postponing the source opening may refer to disclosing a hash value of the source code digest and postponing the time for opening, and for the source opening failure, a special label for the source opening failure may be added, and a developer adds a reason for the source opening failure. It should be noted that the developer may manually set deferred sourcing or non-sourcing.
Exemplary embodiments of the present invention also provide a solution for disclosing audit information for a smart contract.
The server may determine whether the type of the target intelligent contract is a second preset type, where similarly, the second preset type may be a type that is determined by statistics and is of interest to the user, and may also be a type that is helpful for project development after auditing information is disclosed and preset by a developer.
And under the condition that the type of the target intelligent contract is judged to be a second preset type, if a third preset event occurs, the server discloses audit information of the target intelligent contract. Similarly, the third preset event may include any one of the condition that the item is in a financing state, the condition that the item is in a public measurement state, and the condition that the item is in a charging state, it is easily understood that the third preset event may also include a transition period that the item is in a transition from an internal measurement state to a public measurement state, a transition period that the item is in a transition from a non-charging state to a charging state, and the like, and the third preset event is not particularly limited in this exemplary embodiment.
The disclosed audit information may include information about the security audit facilitator and the contents of various aspects of security design. The user can read the audit information through the query interface.
Further, aspects are directed to a scheme for disclosing intelligent contract audit information. Cases of deferred public auditing and no security auditing may also be included. Specifically, deferred public audit refers to that a signature summary of information of the whole security audit process can be submitted for subsequent public verification, and a special label without security audit can be added for non-security audit. It should be noted that developers may manually set deferred disclosure audits or no security audits.
Exemplary embodiments of the present invention also provide a scheme for logging the operational behavior of an administrator for a smart contract.
The server may determine whether the type of the target intelligent contract is a third preset type, where the third preset type may be a type that needs to record administrator behavior and is configured in advance by a developer when the target intelligent contract is constructed.
And the server records the operation behavior of the administrator for the target intelligent contract under the condition that the type of the target intelligent contract is judged to be a third preset type. The operation behaviors may include, for example, the number of released tokens, maintenance mode, etc., and the administrator operation behavior is not particularly limited by the present invention.
In the case of operation behavior being recorded, the user can query the entire maintenance process of the intelligent contract by the administrator through the query interface.
Specifically, for the maintenance management process of the intelligent contract, firstly, a contract administrator standard can be defined, and a contract publisher is an initial administrator authority (the authority can be transferred); subsequently, when a developer writes an intelligent contract, the contract administrator standard can be added to the intelligent contract and executed; then, when the intelligent contract carries out transaction, the server can judge whether the transaction is issued by the administrator or not, and if so, the transaction is marked as maintenance management operation. For example, the intelligent contract may configure a service closing entry, in which case, when the administrator operates the contract, the time point of the operation is recorded, and the whole operation process is transparent.
The exemplary embodiment of the invention also provides a scheme for analyzing the transaction data of the intelligent contract, and the readability of the transaction data is improved.
The server may determine whether the type of the target intelligent contract is a fourth preset type, where the fourth preset type is a type that needs to improve readability of the transaction data and is preset by a developer, and the fourth preset type is not particularly limited in this exemplary embodiment.
Under the condition that the type of the target intelligent contract is judged to be the fourth preset type, if the transaction data are generated based on the target intelligent contract, the transaction data can be analyzed by using the preset parameter tags so as to determine readable information corresponding to the transaction data.
Taking ERC20 transfer interface as an example:
wherein, token (tokens) is a general certificate (or token).
After the smart contract is issued to the blockchain, transaction data without readability may be generated as follows:
in this case, the following parameter tags may be added to the smart contract:
the parameter label is an attribute, and when an intelligent contract is created, the parameter label is analyzed and stored as a contract method parameter signature attribute.
After the transaction data without readability is determined, the transaction data can be analyzed by using the parameter tag, and the obtained readable information is as follows:
the technical scheme of the embodiment of the invention is beneficial to carrying out statistical analysis on the intelligent contract and even the information of the whole block chain by determining the type of the intelligent contract and managing the intelligent contract in the aspects of liveness, source code disclosure, audit information disclosure, administrator operation record, transaction data analysis and the like according to the type, reduces the cost of understanding the block chain by a user and can effectively promote the development of the block chain technology.
