[0012] The embodiment of the present invention provides a method, device and electronic device for verifying the authority of a decentralized autonomous organization. The method is applied to a collaboration initiating terminal. First, a document collaboration transaction to be collaborated is sent to a server so that the server can feedback a collaboration identifier corresponding to the document collaboration transaction. If a collaboration signature application is received from a collaboration application terminal based on the collaboration identifier, a data query request is sent to the server so that the server can feedback the user data corresponding to the collaboration application terminal.

[0013] The embodiment of the present invention provides a permission verification method, device and electronic device for a decentralized autonomous organization, which is applied to a collaboration application terminal. First, a collaboration identifier corresponding to a document collaboration transaction to be collaborated is obtained, and based on the collaboration identifier, a collaboration signature application is sent to the collaboration initiating terminal corresponding to the document collaboration transaction, so that the collaboration initiating terminal feedbacks a collaboration permission signature. Then, based on the collaboration permission signature, a collaboration permission application is initiated to a server, so that the server performs signature verification on the collaboration permission application. When the collaboration permission application passes the signature verification, the document collaboration transaction can be collaborated on. In the above method, after the collaboration initiating terminal sends the document collaboration transaction to be collaborated on to the server, the collaboration application terminal can apply to the collaboration initiating terminal for the collaboration permission signature required to participate in the collaboration, and the collaboration initiating terminal reviews whether to issue the collaboration permission signature to the collaboration application terminal. If the collaboration permission signature issued by the collaboration application terminal is received, the collaboration application terminal can initiate a collaboration permission application to the server, and after it passes the signature verification, the collaboration application terminal can collaborate on the document collaboration transaction. In the embodiment of the present invention, the authority of the document collaboration transaction is completely controlled by the collaboration initiating terminal, and other users cannot change the relevant authority data of the document collaboration transaction, thereby significantly improving the security and transparency of the decentralized autonomous organization collaboration.

[0014] An embodiment of the present invention provides a permission verification method, device and electronic device for a decentralized autonomous organization, which are applied to a server to receive a document collaboration transaction initiated by a collaboration initiating terminal. If the collaboration initiating terminal receives a collaboration signature application sent by a collaboration application terminal based on a collaboration identifier, the server sends a data query request to the server, and the server feeds back the user data corresponding to the collaboration application terminal to the collaboration initiating terminal. When the user data passes the review and verification, the collaboration initiating terminal feeds back the collaboration permission signature to the collaboration application terminal. The collaboration application terminal initiates a collaboration permission application to the server based on the collaboration permission signature. The server performs signature verification on the collaboration permission application, and when the collaboration permission application passes the signature verification, the collaboration application terminal is granted the permission to collaborate on the document collaboration transaction. In the above method, after the collaboration initiating terminal sends the document collaboration transaction to be collaborated to the server, the collaboration applying terminal can apply to the collaboration initiating terminal for the collaboration permission signature required to participate in the collaboration, and the collaboration initiating terminal will review whether to issue the collaboration permission signature to the collaboration applying terminal. If the collaboration permission signature issued by the collaboration applying terminal is received, the collaboration applying terminal can initiate a collaboration permission application to the server, and the server will perform signature verification on it. After the verification is passed, the collaboration applying terminal will be granted the permission to collaborate on the document collaboration transaction, so that the collaboration applying terminal can collaborate on the document collaboration transaction. In the embodiment of the present invention, the permission of the document collaboration transaction is completely controlled by the collaboration initiating terminal, and other users cannot change the relevant permission data of the document collaboration transaction, thereby significantly improving the security and transparency of the collaboration of decentralized autonomous organizations.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] Currently, DAO organizations use web2 permission tools to manage permission data, which has the problem of poor data security. Based on this, the present invention implements a permission verification method, device and electronic equipment for a decentralized autonomous organization, which can significantly improve the security and transparency of decentralized autonomous organization collaboration.

[0028] To facilitate understanding of this embodiment, a method for verifying the authority of a decentralized autonomous organization disclosed in an embodiment of the present invention is first introduced in detail. This method is applied to a collaboration initiating terminal. The collaboration initiating terminal can be understood as an associated terminal of the protocol initiator, such as a smartphone, tablet computer, or personal computer. Figure 1 The flowchart of a method for verifying the authority of a decentralized autonomous organization is shown, and the method mainly includes the following steps S102 to S106:

[0029] Step S102, the document collaboration transaction to be collaborated is sent to the server, so that the server can feedback the collaboration identifier corresponding to the document collaboration transaction. The server can be a server for providing blockchain services. In one embodiment, it is necessary to determine the collaboration start time, collaboration end time and collaboration details corresponding to the document collaboration transaction. The collaboration details are used to describe the relevant information of the document collaboration transaction, including describing the collaboration content, such as community drafts or collaboration rules, etc., to facilitate collaboration applicants to understand the main purpose of the document collaboration transaction and how to collaborate on the document collaboration transaction. The collaboration identifier is also the unique identification number of the document collaboration transaction, which can be a collaboration ID (Identity document, identity identification number), collaboration name, collaboration number, etc. In the specific implementation, the collaboration contract can be called to initiate a document collaboration transaction to the server. After receiving the document collaboration transaction, the server will feedback the collaboration ID corresponding to the document collaboration transaction to the collaboration initiating terminal.

[0030] In step S104, if a collaborative signature application is received from a collaborative application terminal based on a collaborative identifier, a data query request is sent to the server, causing the server to respond with user data corresponding to the collaborative application terminal. The collaborative application terminal can be understood as an associated terminal of the collaborative applicant, such as a smartphone, tablet, or personal computer. The content of the collaborative signature application includes at least the collaborative ID and permission type, which may include editing permission and / or viewing permission. User data can also be referred to as historical contribution behavior data, which may include the number of times the applicant has participated in collaborations and / or collaborative document information, or the number of times the applicant has participated in community proposals and / or information related to initiated proposals.

[0031] In one embodiment, a server is in communication with a DAO Oracle (oracle device). Document collaborators send data query requests to the DAO Oracle through a collaboration initiation terminal. The data query requests may include applicant information such as an applicant ID or address. The DAO Oracle will query the user data corresponding to the applicant information and feed it back to the collaboration initiation terminal. The DAO Oracle may periodically pull historical contribution behavior data from the server and, optionally, feed this historical contribution behavior data back to the collaboration initiation terminal in the form of a report.

[0032] In step S106, if the user data passes the review and verification, the collaboration permission signature is fed back to the collaboration application terminal, so that the collaboration application terminal initiates a collaboration permission application to the server based on the collaboration permission signature and collaborates on the document collaboration transaction when the collaboration permission application passes the signature verification. In one embodiment, the collaboration initiating terminal can display the user data through a graphical user interface for the collaboration initiator to determine whether to issue the collaboration permission signature to the collaboration applicant; in another embodiment, the collaboration initiating terminal can be configured with review rules (such as limiting the number of collaboration participations) and independently determine whether the user data meets the review rules. When the user meets the review rules, it is determined that the user has passed the review and verification.

[0033] Among them, the collaboration permission signature is obtained by signing the collaboration token, collaboration random number (nonce) and the applicant address, collaboration type, and collaboration identifier carried in the collaboration signature application. In one embodiment, the collaboration permission signature and collaboration token can be encrypted and then sent to the collaboration application terminal. The collaboration application terminal initiates a collaboration permission application to the server based on the decrypted collaboration permission signature and collaboration token. The server will generate signature structure data based on the collaboration token, collaboration random number, applicant address, collaboration type, and collaboration identifier to determine the signer address information based on the signature structure data and the collaboration permission signature. If the signer address information is consistent with the initiator address of the document collaboration transaction, it is determined that the collaboration permission application has passed the signature verification. At this time, the collaboration application terminal can collaborate on the document collaboration transaction.

[0034] The embodiment of the present invention provides a permission verification method for a decentralized autonomous organization. After the collaboration initiating terminal sends the document collaboration transaction to be collaborated to the server, the collaboration initiating terminal can review whether to issue a collaboration permission signature to the collaboration application terminal. If it is determined to issue a collaboration permission signature to the collaboration application terminal, the collaboration application terminal can be used to collaborate on the document collaboration transaction after the collaboration permission application initiated by the collaboration application terminal passes the signature verification. In the embodiment of the present invention, the permission of the document collaboration transaction is completely controlled by the collaboration initiating terminal, and other users cannot change the relevant permission data of the document collaboration transaction, thereby significantly improving the security and transparency of the collaboration of the decentralized autonomous organization.

[0035] To facilitate understanding of step S102, this embodiment of the present invention provides a method for sending a document collaboration transaction to a server. This method obtains the collaboration start time, end time, and details. Then, by invoking a collaboration contract, the document collaboration transaction is initiated to the server based on the collaboration start time, end time, and details. For example, the collaboration start time (startTime), end time (endTime), and collaboration details (cooperationDetails) are obtained, and the collaboration contract method #submitCooperation(uint256 startTime, uint256 endTime, String cooperationDetails) returns (uint256 cooperationId) is called to initiate the collaboration with the server. The server then returns the collaboration ID.

[0036] On this basis, the collaboration applicant applies for a collaboration permission signature from the collaboration initiation terminal. The application information includes the collaboration ID and the permission type permissionType (such as "1" for edit type and "0" for view type). After receiving the above application information, the collaboration initiation terminal queries the contribution history behavior data of the collaboration applicant according to the DAO Oracle. The collaboration initiator reviews whether to issue the collaboration permission signature and collaboration token. If the review is passed, the collaboration permission signature of the collaboration applicant is encrypted and sent to the collaboration applicant. Among them, the DAO Oracle occasionally pulls the user's contribution history behavior data from the DAO blockchain service to generate a report. For example, the contribution history behavior data may include the number of times participated in collaboration and collaboration document information, the number of times participated in community proposals or proposals initiated, etc. The signature data CooperationToken of the collaboration permission signature includes at least: applicant address, collaboration ID, collaboration token, and permission type permissionType.

[0037] For ease of understanding, the embodiment of the present invention provides an implementation method for feeding back a collaboration permission signature to a collaboration application terminal, as shown in steps 1 to 4 below:

[0038] Step 1: Send a random number query request to the server to obtain the collaboration random number corresponding to the collaboration applicant terminal. In actual applications, it is determined whether the collaboration applicant is a DAO member (#isMember). If the collaboration applicant is a DAO member, the collaboration initiator queries the collaboration applicant's report from the DAO Oracle. The report records the collaboration applicant's historical contribution behavior data. If the collaboration initiator decides to issue a collaboration permission signature to the collaboration applicant, it will query the collaboration applicant's collaboration random number (#getUserNonce) from the chain. The collaboration random number is also known as the collaboration nonce.

[0039] Step 2: Sign the generated collaboration token, collaboration random number, and the applicant address, collaboration type, and collaboration ID carried in the collaboration signature application to obtain the collaboration permission signature. In one embodiment, a random collaboration token can be generated, and the applicant address, collaboration ID, collaboration token, permission type permissionType can be signed with the signature data CooperationToken structure using EIP712 to generate the collaboration permission signature.

[0040] Step 3: Encrypt the collaboration token and collaboration permission signature using the applicant's public key carried in the collaboration signature application. In one embodiment, the collaboration token and collaboration permission signature can be randomly generated and encrypted using the applicant's public key.

[0041] Step 4: Feedback the encrypted collaboration token and collaboration permission signature to the collaboration application terminal.

[0042] On this basis, the collaboration application terminal will perform a decryption operation on the collaboration authority signature, and the server will perform a signature verification operation on the collaboration authority signature.

[0043] To facilitate understanding of the related operations performed by the collaborative application terminal, the embodiment of the present invention also provides another decentralized autonomous organization authority verification method, which is applied to the collaborative application terminal, see Figure 2 FIG2 is a flow chart of another method for verifying the authority of a decentralized autonomous organization, which mainly includes the following steps S202 to S208:

[0044] Step S202: Obtain the collaboration identifier corresponding to the document collaboration transaction to be collaborated. In one embodiment, the collaboration applicant can view the collaboration identifiers corresponding to all document collaboration transactions to be collaborated stored in the server through the collaboration application terminal. The collaboration application terminal responds to the selection operation for the collaboration identifier to determine the collaboration identifier corresponding to the document collaboration transaction in which the applicant wishes to participate.

[0045] Step S204, based on the collaboration identifier, sends a collaboration signature application to the collaboration initiating terminal corresponding to the document collaboration transaction, so that the collaboration initiating terminal can feedback the collaboration permission signature. The collaboration signature application is used to apply for a collaboration permission signature. In one embodiment, the collaboration applicant applies for a collaboration permission signature from the collaboration initiating terminal, and the application information includes a collaboration ID and a permission type permissionType. The permission type permissionType includes: "1" for editing type and / or "0" for viewing type. In one embodiment, after receiving the collaboration signature application, the collaboration initiating terminal will query the historical contribution behavior data corresponding to the collaboration applicant from the DAO Oracle and review it. When the review is passed, the collaboration permission signature will be fed back to the collaboration application terminal. The specific process of the collaboration initiating terminal sending the collaboration permission signature can be found in the aforementioned steps 1 to 4, which will not be repeated in the embodiments of the present invention.

[0046] Step S206: Initiate a collaboration permission application to the server based on the collaboration permission signature, so that the server can perform signature verification on the collaboration permission application. In one embodiment, the applicant uses the private key to decrypt the collaboration permission signature, obtain the decrypted collaboration permission signature and collaboration token, and initiate collaboration using the plaintext signature and collaboration information, where the collaboration information includes at least the collaboration ID, collaboration token, permission type permissionTyp, etc.

[0047] Step S208: When the collaboration permission application passes the signature verification, collaboration is performed on the document collaboration transaction.

[0048] The embodiment of the present invention provides a permission verification method for a decentralized autonomous organization. After the collaboration initiating terminal sends the document collaboration transaction to be collaborated to the server, the collaboration applying terminal can apply to the collaboration initiating terminal for the collaboration permission signature required for participating in the collaboration, and the collaboration initiating terminal will review whether to issue the collaboration permission signature to the collaboration applying terminal. If the collaboration permission signature issued by the collaboration applying terminal is received, the collaboration applying terminal can initiate a collaboration permission application to the server, and after it passes the signature verification, use the collaboration applying terminal to collaborate on the document collaboration transaction. In the embodiment of the present invention, the permission of the document collaboration transaction is completely controlled by the collaboration initiating terminal, and other users cannot change the relevant permission data of the document collaboration transaction, thereby significantly improving the security and transparency of the collaboration of the decentralized autonomous organization.

[0049] To facilitate understanding of the above-mentioned step S206, an embodiment of the present invention further provides an implementation method for initiating a collaboration permission application to a server based on a collaboration permission signature, specifically: (1) receiving an encrypted collaboration token and a collaboration permission signature; (2) using the applicant's private key to decrypt the encrypted collaboration token and collaboration permission signature to obtain a decrypted collaboration token and collaboration permission signature, wherein the decrypted collaboration permission signature is a plaintext signature; (3) based on the decrypted collaboration token and collaboration permission signature, initiating a collaboration permission application to the server. Exemplarily, the collaboration application terminal will use the plaintext signature, collaboration ID, collaboration token and permission type to initiate collaboration to the server.

[0050] On this basis, the server will perform signature verification operations for the collaborative authority signature.

[0051] To facilitate understanding of the related operations performed by the server, the embodiment of the present invention also provides another decentralized autonomous organization authority verification method, which is applied to the server, see Figure 3 FIG. 1 is a flow chart of another decentralized autonomous organization authority verification method, which mainly includes the following steps S302 to S306:

[0052] Step S302: receiving a document collaboration transaction initiated by a collaboration initiating terminal; wherein the collaboration initiating terminal is used to receive a collaboration signature application sent by a collaboration applying terminal based on a collaboration identifier, and send a data query request to a server.

[0053] In step S304, the user data corresponding to the collaboration application terminal is fed back to the collaboration initiation terminal; wherein, the collaboration initiation terminal is also used to feed back the collaboration permission signature to the collaboration application terminal when the user data passes the review and verification, and the collaboration application terminal is used to initiate a collaboration permission application to the server based on the collaboration permission signature. In one embodiment, DAOOracle can be used to query the user data corresponding to the collaboration application terminal, wherein DAOOracle will periodically pull historical contribution behavior data from the server and generate relevant reports, and DAOOracle will feed back the historical contribution behavior data to the collaboration initiation terminal in the form of reports.

[0054] Step S306: Verify the signature of the collaboration permission request. If the collaboration permission request passes the signature verification, the collaboration requesting terminal is granted permission to collaborate on the document collaboration transaction. In one embodiment, the collaboration contract method #validCorpTokenSign(uint256cooperationId,uint8 permissionType,bytestoken,bytes signature)public returns(bool) can be called for on-chain verification. If the collaboration permission request passes the signature verification, the collaboration requesting terminal is granted permission to collaborate on the document collaboration transaction.

[0055] The embodiment of the present invention provides a permission verification method for a decentralized autonomous organization. After the collaboration initiating terminal sends the document collaboration transaction to be collaborated to the server, the collaboration applying terminal can apply to the collaboration initiating terminal for the collaboration permission signature required for participating in the collaboration, and the collaboration initiating terminal reviews whether to issue the collaboration permission signature to the collaboration applying terminal. If the collaboration permission signature issued by the collaboration applying terminal is received, the collaboration applying terminal can initiate a collaboration permission application to the server, and the server performs signature verification on it. After the verification is passed, the collaboration applying terminal is granted the permission to collaborate on the document collaboration transaction, so that the collaboration applying terminal can collaborate on the document collaboration transaction. In the embodiment of the present invention, the permission of the document collaboration transaction is completely controlled by the collaboration initiating terminal, and other users cannot change the relevant permission data of the document collaboration transaction, thereby significantly improving the security and transparency of the collaboration of the decentralized autonomous organization.

[0056] To facilitate understanding of the above step S306, the embodiment of the present invention further provides an implementation method for performing signature verification on the collaboration permission application, as shown in the following steps a to d:

[0057] Step a: Obtain the collaboration random number corresponding to the collaboration application terminal. In one embodiment, if the collaboration is verified to be in the collaboration state, the collaboration nonce corresponding to the collaboration application terminal will be obtained from userNonceMap.

[0058] Step b: Generate signature structure data based on the collaboration token, applicant address, collaboration type, and collaboration ID in the collaboration permission application. In one embodiment, 3. Generate signature structure data hash based on the applicant address, collaboration ID, collaboration token, and permission type permissionType.

[0059] Step c: Recover the signer address based on the collaboration authority signature and the signature structure data. In one embodiment, the signer address can be recovered from the signature structure data hash and the collaboration authority signature.

[0060] In step d, if the signer's address matches the initiator's address corresponding to the collaboration initiating terminal, the collaboration permission application is determined to have passed signature verification. In one embodiment, if the signer's address matches the collaborative document initiator's address, permission verification is successful, and a collaboration nonce is added to prevent duplicate authentication. In actual applications, once on-chain verification is successful, the collaboration requesting terminal can collaborate.

[0061] To facilitate understanding of the above embodiments, the present invention provides Figure 4 The flowchart of another permission verification method of a decentralized autonomous organization is shown in FIG. 1 , specifically: (1) the collaboration initiator initiates a document collaboration to the DAO blockchain service; (2) the collaboration applicant applies for collaboration permissions; (3) the collaboration initiator queries user data from the DAO Oracle, the collaboration initiator queries the collaboration nonce from the DAO blockchain service, the collaboration initiator generates a collaboration token and signs it, and the collaboration initiator encrypts the assistance token and collaboration permission signature and sends them to the collaboration applicant; (4) the collaboration applicant decrypts the collaboration token and collaboration permission signature, and the collaboration applicant initiates collaboration to the DAO blockchain service.

[0062] In actual applications, the prerequisites for executing the above (1) to (4) include: deploying the DAO collaboration contract and initializing the DAO organization members; users initiate DAO member proposals and join the DAO.

[0063] In one embodiment, the conceptual model of the permission verification method of a decentralized autonomous organization provided by an embodiment of the present invention includes: (1) collaboration document CooperationDocument: collaboration ID, collaboration initiator, collaboration details, document status (collaboration in progress or completed), collaboration start time, collaboration end time; (2) permission type permissionType: 1 edit, 0 view; (3) signature data CooperationToken: applicant address, collaboration ID, collaboration token, permission type permissionType.

[0064] In one embodiment, the data storage content includes: (1) collaboration document: used to store collaboration document information, the pseudo code is as follows: mapping(uint256=>CooperationDocument)private_cooperationDocumentQueue; (2) collaboration user nonce: used for anti-duplicate, the pseudo code is as follows: mapping(address=>uint256)private_userNonceMap; (3) member: the pseudo code is as follows: mapping(address=>bool)private_memberMap.

[0065] Based on the above embodiments, the present invention provides an application example of a method for verifying the authority of a decentralized autonomous organization. Specifically:

[0066] (a) Initialize the DAO collaboration contract. In practice, the DAO member addresses can be initialized. The pseudo code is as follows: initDAO(address[]initMember). When a new member joins the DAO organization, they can join the DAO organization by initiating a proposal.

[0067] (b) Initiate collaboration. The pseudo code is as follows: submitCooperation(uint256 startTime, uint256 endTime, String cooperationDetails) returns(uint256 cooperationId).

[0068] (c) Verify the authority signature. The pseudo code is as follows:

[0069] validCorpTokenSign(uint256 cooperationId, uint8 permissionType, bytestoken, bytes signature) public returns(bool); {0. Verify that the collaboration is in a collaborative state; also ensure that it is a DAO member; 1. Obtain the user nonce from userNonceMap; 2. Generate a signature structure data hash based on the applicant address, collaboration ID, collaboration token, and permission type permissionType; 3. Recover the signer address from the structure data hash and signature; 4. If the signer address is consistent with the address of the collaboration document initiator, permission verification is successful}.
