Description

Technical Field

[0001] The present application relates to the field of blockchain technology, and specifically, to a blockchain-based project management method, device, storage medium and electronic device. Background Art

[0002] In the related technology, when conducting cross-institutional software engineering R&D projects, the R&D process and output products of the software engineering R&D projects are managed by management personnel. The management personnel are one of the institutions involved in the software engineering R&D project and act as the management party. They use the R&D management system to manage the project, or the relevant data and assets are handed over to a third party other than the institution involved in the software engineering R&D project for management.

[0003] However, since project management relies on the management party to be carried out, the security of the project depends on the behavior of the management party, which is prone to potential safety hazards. In the process of cross-institutional software engineering research and development, project management through the management party cannot ensure the rigor of the two aspects of research and development tasks and personnel input, and research and development tasks and asset output. In addition, the project quality assurance in the existing technology mainly relies on two modes: static inspection and test verification. If the project development involves high security requirements, it is necessary to invest very high human resource costs to ensure the quality of the project, otherwise it is easy to cause huge investment risks.

[0040] Digital token: a cryptographic equity certificate in digital form;

[0041] Formal verification: Using mathematical methods to prove the correctness or incorrectness of a computer hardware or software system based on one or more formal specifications or properties.

[0042] According to an embodiment of the present application, a blockchain-based project management method is provided.

[0043] Figure 1 This is a flowchart of a blockchain-based project management method provided according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0044] Step S102, calling the first smart contract from the blockchain to create a project development task, and verifying the task information and participants in the project development task, wherein the first smart contract is used to manage tasks.

[0045] Specifically, the project development task may be a software development task issued by a project management system, and the participants are various organizations involved in the software development task, including developers and testers. Figure 2 is a schematic diagram of the data structure of task information provided according to an embodiment of the present application, such as Figure 2 As shown, the data structure of the task information is represented by the task information block 201, which may include: block height, previous block hash, task information, task participants, task status, and task creation time.

[0046] Step S104: When the task information and the participants are verified, the developer and the tester among the participants are determined, and a second smart contract is called from the blockchain to assign digital identities to the developer and the tester, wherein the second smart contract is used to manage digital identities.

[0047] Specifically, the developer is responsible for the project development of the software development task, including writing design documents, interface documents, etc., as well as coding and self-testing. The tester is responsible for testing the developer's research and development results, including writing test design documents, user manuals, and completing the development of test cases. Digital identity is the identity certificate of the developer and the tester on the blockchain. With digital identity, the research and development institutions corresponding to each node on the blockchain can recognize and verify each other's identity information. Figure 3 is a schematic diagram of the data structure of a digital identity provided according to an embodiment of the present application, such as Figure 3 As shown, the digital identity may include: identity certificate 301, certificate summary 302. Identity certificate 301 is stored in the blockchain and includes: certificate ID, issuer identity certificate, declaration information, signature information. Certificate summary 302 is stored in the blockchain and includes: certificate ID, declaration hash.

[0048] Step S106, calling the developer to develop the project according to the task information to obtain the development result, and calling the tester to test the development result to obtain the test result.

[0049] Specifically, the development results include software code, development design documents and interface documents, etc., and the test results include test case development code, test design documents and user manuals, etc.

[0050] Step S108, calling the third smart contract from the blockchain to perform digital token authentication on the development results and the test results, and if the development result authentication is passed, obtaining the first digital token asset, and if the test result authentication is passed, obtaining the second digital token asset, wherein the third smart contract is used to manage digital tokens.

[0051] Specifically, digital token authentication encrypts the development results and test results and stores them on the blockchain in the form of digital token assets. Figure 4is a schematic diagram of the data structure of a digital token asset provided according to an embodiment of the present application, such as Figure 4 As shown, the digital token asset is represented by the digital token information block 401, and the digital token information block 401 may include: block height, previous block hash, digital token asset information, associated task information, associated identity certificate, and digital token asset creation time.

[0052] Step S110, calling the first smart contract from the blockchain to verify the first digital token asset and the second digital token asset, and when both the first digital token asset and the second digital token asset are verified, the project development task is calculated.

[0053] Specifically, the first digital token asset and the second digital token asset are verified to determine whether the project has been successfully developed, and the project development tasks are accounted for to review the project development process and determine the contribution of each institution involved in the project development to the project.

[0054] The blockchain-based project management method provided in the embodiment of the present application creates a project development task by calling a first smart contract from the blockchain, and verifies the task information and participants in the project development task, wherein the first smart contract is used to manage the task; when the task information and the participants are verified, the developer and the tester among the participants are determined, and the second smart contract is called from the blockchain to assign digital identities to the developer and the tester, wherein the second smart contract is used to manage the digital identity; the developer is called to develop the project according to the task information to obtain the development result, and the tester is called to test the development result to obtain the test result; the third smart contract is called from the blockchain to perform digital token authentication on the development result and the test result, and when the development result authentication is passed, the first digital token asset is obtained, and when the test result authentication is passed, the second digital token asset is obtained, wherein the third smart contract is used to manage the digital token; the first smart contract is called from the blockchain to verify the first digital token asset and the second digital token asset, and when the first digital token asset and the second digital token asset are both verified, the project development task is accounted for, which solves the problem of low security in the related art that the management party is relied on to manage the R&D project. Based on blockchain technology, by allocating digital identities, participants can perform project tasks based on digital identities, convert project results into digital token assets, and conduct formal verification of digital token assets, thereby achieving the effect of ensuring the security of project management and improving the quality of R&D results.

[0055] After obtaining the project development task, it is necessary to verify the task information and participants. Optionally, in the blockchain-based project management method provided in the embodiment of the present application, verifying the task information and participants in the project development task includes: determining whether the private key held by the participant matches the public key of the blockchain, and if the private key matches the public key, determining that the identity verification of the participant has passed; if the identity verification of the participant has passed, determining whether the task information complies with the preset business rules, and if the task information complies with the preset business rules, determining that the task information verification has passed.

[0056] Specifically, the public key on the blockchain is matched with the private key held by the participant. If the match is successful, the identity verification of the participant is passed. The preset business rules are the general rules in the industry that the software to be developed in the project development task must meet. By creating a new project development task, entering the task information and participant information, the task management smart contract of the blockchain verifies the task information, including data validity verification and business rule verification. The identity management smart contract of the blockchain verifies the participants in the task, including data validity verification and business rule verification. By verifying the task information and participants in the project development task, the security of project development is guaranteed.

[0057] After the verification is passed, a digital identity needs to be assigned to the participant. Optionally, in the blockchain-based project management method provided in the embodiment of the present application, the developer and the tester among the participants are determined, and a second smart contract is called from the blockchain to assign digital identities to the developer and the tester, including: generating a first digital identity credential for the developer, and generating a second digital identity credential for the tester; storing the subject information in the first digital identity credential to the developer, and storing the summary information of the first digital identity credential to the blockchain; storing the subject information in the second digital identity credential to the tester, and storing the summary information of the second digital identity credential to the blockchain.

[0058] Specifically, Figure 5 This is a flowchart of digital identity allocation according to an embodiment of the present application. When a new digital identity needs to be added and allocated, such as Figure 5 As shown in the figure, the project management system receives the identity request, calls up the identity management smart contract, and initiates the digital identity startup process. The identity management smart contract verifies the validity of the application data in the request to ensure the validity of the data. After the validity verification is passed, the identity management smart contract reviews the application data based on the pre-established business rules to ensure the legitimacy of the data. After the review is completed, a digital identity certificate is generated. The subject credential information is stored in the blockchain and is saved and maintained by the applicant. The summary information of the credential is stored on the blockchain. All institutions connected to the blockchain node on the blockchain can verify the credential summary. The identity information security of R&D personnel is guaranteed by allocating digital identities.

[0059] After the digital identity is allocated, it is necessary to allocate tasks corresponding to the digital identity to the participants. Optionally, in the blockchain-based project management method provided in the embodiment of the present application, before calling the developer to perform project development based on the task information and obtaining the development results, the method also includes: obtaining the digital identity credentials of all participants, and determining whether the digital identity credentials of each participant are the first digital identity credentials; obtaining the participants whose digital identity credentials are the first digital identity credentials, obtaining the first participant, and assigning the project development task to the first participant; before calling the tester to test the development results and obtaining the test results, the method also includes: obtaining the digital identity credentials of all participants, and determining whether the digital identity credentials of each participant are the second digital identity credentials; obtaining the participants whose digital identity credentials are the second digital identity credentials, obtaining the second participant, and assigning the project testing task to the second participant.

[0060] Specifically, the first digital identity certificate is the digital identity certificate corresponding to the development, the first participant is the developer, the second digital identity certificate is the digital identity certificate corresponding to the tester, and the second participant is the tester. Each R&D organization in the project management system will have two roles: developer and tester. Different organizations can be both developers and testers. After a project R&D task is created, the organization that undertakes the development task and the organization that undertakes the test task will be identified through the task information and participant information.

[0061] Figure 6 is a flowchart of a developer performing a development task according to an embodiment of the present application, such as Figure 6 As shown, the developer receives a development task assignment request, calls up the task management smart contract, queries the development task details based on the request information, and the task management smart contract analyzes the task details and assigns the task to the corresponding R&D personnel based on the R&D personnel's digital identity. The R&D personnel accept the task and carry out R&D work, specifically writing development design documents, interface documents, etc., as well as coding and self-testing work. After completing the task, the R&D personnel output documents or source code, which are R&D assets, and submit them in the project management system.

[0062] Figure 7 is a flowchart of a test party performing a test task according to an embodiment of the present application, such as Figure 7As shown, the tester receives the test task assignment request, calls up the task management smart contract of the organization, queries the detailed information of the test task based on the request information, analyzes the detailed information of the task, and assigns the task to the corresponding tester based on the digital identity of the tester. The tester accepts the task and performs the test work, specifically writing the test design document, user manual, and completing the development of the test case. When developing the test case, the test model is performed, and the formal verification model is completed according to the requirements and functions to be implemented by the module to be tested. This model can verify the source code assets submitted by the development after deployment. After completing the task, the tester outputs the document and test case, which are the test assets, and submits them in the project management system. By assigning the corresponding development tasks and test tasks to the developer and the tester, the project development can be completed efficiently.

[0063] After the development task and the test task are completed, the obtained development results and test results are digitally authenticated as assets. Optionally, in the blockchain-based project management method provided in the embodiment of the present application, a third smart contract is called from the blockchain to digitally authenticate the development results and test results, and if the development result authentication passes, the first digital token asset is obtained, and if the test result authentication passes, the second digital token asset is obtained, including: verifying whether the development result is a duplicate digital asset, and if the development result is not a duplicate digital asset, verifying whether the development result can run normally; if the development result can run normally, determining the developer and task information corresponding to the development result; performing digital token authentication based on the development result, the developer and the task information, and if the authentication passes, obtaining the first digital token asset; verifying whether the test result is a duplicate digital asset, and if the test result is not a duplicate digital asset, verifying whether the test result can run normally; if the test result can run normally, determining the test party and task information corresponding to the test result; performing digital token authentication based on the test result, the test party and the task information, and if the authentication passes, obtaining the second digital token asset.

[0064] Specifically, duplicate digital assets are development results or test results that are repeatedly uploaded by R&D personnel in order to meet workload. The developer and tester verify the development results and test results through simulation runs performed by their own organizations.

[0065] Figure 8 This is a flowchart of digital token asset authentication and release provided in an embodiment of the present application, such as Figure 8As shown, after the project management system receives the development results and test results, it calls the asset management smart contract to receive the development results and test results. The asset management smart contract verifies the development results and test results, including verifying the availability of the development results and test results and whether they are repeated. After the verification is passed, the development result information and the test result information are associated with the task information and the personnel identity information to confirm the tasks and personnel corresponding to the development results and test results. The development results and the test results are digitally authenticated to form the first digital token asset and the second digital token asset. After the digital token asset is formed, the first digital token asset and the second digital token asset have unique identifiers in the blockchain network, which can be verified and traced back to the tasks and personnel corresponding to the first digital token asset and the second digital token asset. The first digital token asset and the second digital token asset cannot be copied. If the first digital token asset and the second digital token asset are tampered with, the tampered digital token asset cannot correspond to the original digital token asset and will not pass the verification. The first digital token asset and the second digital token asset are published. By authenticating the development results and test results as the first digital token assets and the second digital token assets, the security of the R&D results is effectively guaranteed.

[0066] After obtaining the first digital token asset and the second digital token asset, it is also necessary to verify the first digital token asset and the second digital token asset. Optionally, in the blockchain-based project management method provided in the embodiment of the present application, calling the first smart contract from the blockchain to verify the first digital token asset and the second digital token asset includes: deploying the first digital token asset and the second digital token asset to the project management system to obtain the deployment result; determining the test data in the second digital token asset, running the test data according to the deployment result, and obtaining the preset test result; comparing the preset test result with the test result corresponding to the second digital token asset; when the test result is the same as the preset test result, performing logic verification on the first digital token asset; when the first digital token asset passes the logic verification, determining that both the first digital token asset and the second digital token asset have passed the verification.

[0067] Specifically, the deployment result is to deploy the test data corresponding to the second digital token asset to the corresponding system that can run the test data, and the preset test data is the running result obtained after running the test data. Logical verification is to verify whether the code corresponding to the first digital token asset complies with the preset logical rules one by one according to mathematical methods.

[0068] Fig. 9 is a flowchart of verifying a first digital token asset and a second digital token asset according to an embodiment of the present application, such as Fig. 9As shown, the project management system calls up the task management smart contract of the organization and extracts the first digital token asset and the second digital token asset to be verified. The verifier deploys the first digital token asset and the second digital token asset to be verified, executes the formal verification test case in the formal verification module of the project management system, and receives the preset test results in the functional module of the project management system. The preset test results and the test results corresponding to the second digital token asset are compared. This is the first stage of verification. If the test results are the same as the preset test results, it means that the verification is passed. After completing the first stage of verification, the first digital token asset is analyzed internally. This is the second stage of verification, and the verification results of the two stages are finally summarized. When the result is verification passed, the task management smart contract updates the status of the project development task. When the result is verification failure, the task management smart contract returns the project development task to the verifier and notifies the R&D personnel and testers to troubleshoot the problem based on the verification results. By verifying the first digital token asset and the second digital token asset, the high quality of the R&D results is guaranteed.

[0069] It should be noted that Fig.10 It is a structural diagram of a formal verification module provided according to an embodiment of the present application. The formal verification module includes: a second digital token asset processing module 1001, a verification model module 1002, a second digital token asset verification module 1003, a result analysis module 1004, and a result output module 1005. The second digital token asset processing module 1001 is responsible for obtaining the second digital token asset and parsing the second digital token asset. The verification model module 1002 is responsible for collecting and inputting the formal verification model. The second digital token asset verification module 1003 is responsible for selecting the corresponding formal verification model for the second digital token asset and verifying it. The result analysis module 1004 is responsible for analyzing the results after the second digital token asset is verified, and comparing whether the preset test results and the test results corresponding to the second digital token asset are the same. The result output module 1005 is responsible for outputting the result of whether the verification is passed, and can support data output, file output, report output, etc.

[0070] For example, a formal verification method of an embodiment of the present application is to first mark some "preconditions" and "postconditions" for the code or process in the first digital token asset, and then perform logical reasoning to verify the basic properties of the code or process in the first digital token asset. For example, the code is: {x=0}x:=x+1{x>0}, which means that if x is equal to 0 at the beginning, then after x:=x+1 is executed, x should be greater than 0. The precondition here is x=0, and the postcondition is x>0. If x starts with zero, after executing x:=x+1, x will be greater than 0, so this code is verified.

[0071] In the formal verification module of the present invention, by formally modeling the code or process involved in the second digital token asset, a corresponding formal verification model is selected for the second digital token asset. During the verification process, the pre- and post-conditions in the model are concatenated with the code or process in the asset. Through logical deduction and verification, it can be concluded that when the pre-condition is satisfied, after the verification execution, the post-condition must hold. If all these conditions are met, the second digital token asset verification module and the result analysis module consider this to be correct. That is, by means of mathematics, the security and functional correctness of the code or process in the second digital token asset are strictly proven, and it can effectively detect whether there are security vulnerabilities and logical vulnerabilities in the result of the second digital token asset.

[0072] For example, for the following code: int10 c = a + b, if it is necessary to check whether there is an overflow vulnerability, the integer type can be modeled and a formal rule can be defined: Int10.repr: Z -> int10. This rule obtains a 10-bit machine integer by intercepting the lower 10-bit value of a pure mathematical integer (with a value range from negative infinity to positive infinity). Then, write the formal specification of the addition operation as follows: Set the pre-condition for code execution to ensure that the types of a and b are 10-bit signed machine integers {a: int10, b: int10}; the source code program of the addition operation {c = a + b;}; set the post-condition for correct code execution {(int10.repr(a + b)) / ((Int10.repr(a + b)) = (a + b))}, where (int10.repr(a + b)) is described to prove whether the functional correctness of the code is satisfied, that is, it is necessary to prove that the source code performs addition on a and b rather than subtraction or any other operation logic, and converts the operation result to the int10 type.

[0073] In addition, it is necessary to prove the security property of whether there is an overflow. Therefore, add the post-condition: ((Int10.repr(a + b)) = (a + b)). When a + b > int10.max_singed or a + b < int10.min_signed, it will result in (Int10.repr(a + b)) ≠ (a + b). Finally, prove whether the execution of the code satisfies the above post-condition according to the pre-condition. If an unprovable result is generated, it indicates that the program function is incorrect or there is an overflow security vulnerability. Then, analyze and modify the source program according to the proof result, and then prove it again until the proof passes. By using this mathematical proof method, the code is formally described as a formula, and its properties are also proven for other logical vulnerabilities and security vulnerabilities. Based on this principle, the verification of the functional correctness and security properties of the digital token asset is realized.

[0074] After the first digital token asset and the second digital token asset are verified, optionally, in the blockchain-based project management method provided in the embodiment of the present application, accounting for the project development task includes: determining a preset developer number range, a preset tester number range, and a preset R&D time range; obtaining the number of developers and the number of testers, determining whether the number of developers falls within the preset developer number range, and determining whether the number of testers falls within the preset tester number range; if the number of developers falls within the preset developer number range, and the number of testers falls within the preset tester number range, determining whether the time consumed by the project development task falls within the preset R&D time range; if the time consumed by the project development task falls within the preset R&D time range, determining that the project development task accounting has passed.

[0075] Specifically, Fig.11 is a flowchart of project development task accounting provided in an embodiment of the present application, such as Fig.11 As shown, after the first digital token asset and the second digital token asset are verified, the processing steps of the project development task accounting are as follows: the task management smart contract summarizes the task information, asset information and personnel information, performs statistical analysis of the data, and forms a data view of the project development task. Perform formal verification on the task information, asset information and personnel information in the data view, and the formal verification module of the project accounting is based on the task information, asset information and personnel information modeling, and incorporates the task information of the project development task into the model analysis to obtain the preset developer number range, the preset tester number range and the preset R&D time range, and analyze and compare the actual personnel input and output assets with the expectations of the formal verification output to determine whether the number of developers falls within the preset developer number range, and whether the number of testers falls within the preset tester number range. If the number of developers falls within the preset developer number range, and the number of testers falls within the preset tester number range, it is determined whether the time consumed by the project development task falls within the preset R&D time range; if the time consumed by the project development task falls within the preset R&D time range, it is determined that the project development task accounting has passed. If the accounting fails, the task management smart contract will submit the project development task to the accounting personnel, who will review the status of the project development task and audit the project development task process. The project development task returns to the unclosed loop state and waits for the audit results.
