Description

Technical Field

[0001] The present application relates to the field of blockchain technology, and specifically to a smart contract operation management method, device, equipment and computer storage medium. Background Art

[0002] The consortium chain is aimed at members of a specific group and limited third parties. It designates multiple pre-selected nodes as bookkeepers. The generation of each block is jointly decided by all pre-selected nodes in the consortium chain. Other access nodes can participate in transactions but do not inquire about the accounting process. Other third parties can perform limited queries through the open API of the blockchain.

[0003] At present, there are usually no restrictions on the management of smart contracts on the alliance chain. Clients with blockchain call permissions can deploy smart contracts at will. As for the update, freezing and unfreezing operations of deployed smart contracts, there are usually two existing practices: one is to only allow the smart contract deployer to have the authority to operate; the other is to allow all alliance members holding nodes to vote to operate; the existing permission control rules for smart contract-related operations are basically fixed rules and lack flexibility; if the object served by a smart contract is not all members of a alliance chain, it is unreasonable to require all members of the alliance chain to vote on the operation of the smart contract.

The smart contract operation management scenario in the embodiment of the present invention includes a smart contract operation management device 100 (a smart contract operation management device is integrated in the smart contract operation management device 100), and a computer storage medium corresponding to the smart contract operation management is run in the smart contract operation management device 100 to execute the steps of smart contract operation management.

[0063] Understandably, Figure 1 The smart contract operation management device in the scenario of smart contract operation management shown, or the devices included in the smart contract operation management device, does not constitute a limitation on the embodiments of the present invention. That is, the number of devices and types of devices included in the scenario of smart contract operation management, or the number of devices and types of devices included in each device, do not affect the overall implementation of the technical solution in the embodiment of the present invention, and can all be regarded as equivalent replacements or derivatives of the technical solution claimed to be protected in the embodiment of the present invention.

[0064] The smart contract operation management device 100 in the embodiment of the present invention is mainly used for:

[0065] Receive a contract update request, and obtain a target proposal associated with the contract update request;

[0066] Broadcasting the target proposal to all nodes in the alliance chain so that each node in the alliance chain can vote on the target proposal;

[0068] If the number of valid votes meets the voting approval rules corresponding to the target proposal, the smart contract is updated according to the target contract code in the target proposal.

[0069] In the embodiment of the present invention, the smart contract operation management device 100 may be an independent smart contract operation management device, or a smart contract operation management device network or a smart contract operation management device cluster composed of smart contract operation management devices. For example, the smart contract operation management device 100 described in the embodiment of the present invention includes but is not limited to a computer, a network host, a single network smart contract operation management device, a set of multiple network smart contract operation management devices, or a cloud smart contract operation management device composed of multiple smart contract operation management devices. Among them, the cloud smart contract operation management device is composed of a large number of computers or network smart contract operation management devices based on cloud computing.

[0070] Those skilled in the art will understand that Figure 1 The application environment shown in the figure is only one application scenario of the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may also include Figure 1 More or fewer smart contract operation management devices as shown in , or smart contract operation management device network connection relationships, such as Figure 1 Only one smart contract operation management device is shown. It can be understood that the scenario of smart contract operation management may also include one or more other smart contract operation management devices, which are not limited here.

[0071] In addition, in the scenario of smart contract operation management of the present application, the smart contract operation management device 100 may be provided with a display device, or the smart contract operation management device 100 may not be provided with a display device and may be communicated with an external display device 200, and the display device 200 is used to output the result of the execution of the smart contract operation management method in the smart contract operation management device. The smart contract operation management device 100 may access a backend database 300 (the backend database may be in the local memory of the smart contract operation management device, or may be set in the cloud), and the backend database 300 may store information related to smart contract operation management.

[0072] It should be noted that Figure 1 The scenario diagram of smart contract operation management shown is only an example. The scenario of smart contract operation management described in the embodiment of the present invention is to more clearly illustrate the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention.

[0073] Based on the above scenario of smart contract operation management, an embodiment of a smart contract operation management method is proposed.

[0074] Reference Figure 2 , Figure 2This is a flow chart of an embodiment of a smart contract operation management method in an embodiment of the present application. The smart contract operation management method includes steps 201-204:

[0075] 201. Receive a contract update request and obtain a target proposal associated with the contract update request.

[0076] In this embodiment, the smart contract operation management method is applied to a smart contract operation management device, also called a node device. The type of smart contract operation management device is not specifically limited. For example, the smart contract operation management device can be a terminal or a server. In this embodiment, the terminal is used as an example for explanation.

[0077] The terminal receives a contract update request, wherein the contract update request may be actively triggered by the user, for example, the user clicks the "xxx update" button on the terminal display interface to actively trigger the contract update request; in addition, the contract update request may also be automatically triggered by the terminal, for example, the triggering condition for the contract update request is pre-set in the terminal as: when transaction information is generated; the terminal monitors the changes in the transaction information in real time, and the contract update request is automatically triggered when the terminal detects that the transaction information is generated; for another example, the triggering condition for the contract update request is pre-set in the terminal as: when the transaction operation is completed; the terminal monitors the operation of the transaction information in real time, and the terminal automatically triggers the contract update request when it detects that the transaction operation is completed.

[0078] After the terminal receives the contract update request, the terminal obtains the target proposal associated with the contract update request, where the target proposal includes but is not limited to: the target contract code, the smart contract address (the smart contract address refers to the address information of the storage area of ​​the initial contract source code) and the signature of the update submitter.

[0079] 202. Broadcast the target proposal to all nodes in the alliance chain, so that each node in the alliance chain votes on the target proposal.

[0080] After the terminal obtains the target proposal associated with the contract update request, the terminal broadcasts the target proposal to all nodes in the alliance chain. Other nodes in the alliance chain receive the target proposal and store it in the proposal pool. The target proposal is in a voting state. Users corresponding to other nodes can query the target proposal in the proposal pool. Other nodes vote on the target proposal and send the votes to the terminal. That is, other nodes vote, other nodes obtain the update submitter tag in the target proposal, and other nodes feed back the votes to the terminal based on the update submitter tag.

[0081] 203, receiving votes from each node in the alliance chain, extracting valid votes of the contract council members corresponding to the target proposal in the votes, and counting the number of valid votes.

[0082] The terminal receives votes from each node in the alliance chain, obtains the smart contract address in the target proposal, obtains the list of contract council member addresses associated with the smart contract address, determines whether the vote is a valid vote of a contract council member in the list of contract council member addresses, extracts the valid votes corresponding to the contract council members, and counts the number of valid votes to determine whether to perform the update operation, specifically including:

[0083] Step a1, receiving votes from each node in the alliance chain, obtaining the voter label corresponding to the vote, and determining whether the voter corresponding to the voter label is a member of the contract council corresponding to the target proposal;

[0084] Step a2: If the voter corresponding to the voter tag is not a member of the contract council, the vote is considered invalid and deleted;

[0085] Step a3: If the voter corresponding to the voter tag is a member of the contract council, the vote is regarded as a valid vote and the number of valid votes is counted.

[0086] That is, the terminal receives votes from each node in the alliance chain, and the terminal obtains the voter label corresponding to the vote; the terminal obtains the smart contract address in the target proposal, and the terminal obtains the contract council member address list associated with the smart contract address (the contract council member address list contains the contract council member information), and the terminal determines whether the voter corresponding to the voter label is a member of the contract council corresponding to the target proposal; if the voter corresponding to the voter label is not a member of the contract council, the terminal will treat the vote as an invalid vote, and the terminal will delete the invalid vote; if the voter corresponding to the voter label is a member of the contract council, the terminal will treat the vote as a valid vote, and the terminal will count the number of valid votes. In this embodiment, the terminal determines the validity of the vote based on the voter label associated with the vote, which can make the operation and management of smart contracts more targeted.

[0087] 204. If the number of valid votes meets the voting approval rule corresponding to the target proposal, the smart contract is updated according to the target contract code in the target proposal.

[0088] In this embodiment, the terminal obtains the smart contract address in the target proposal, and obtains the preset voting permission rule corresponding to the smart contract address (the voting permission rule can be created when the smart contract is created, and the voting permission rule can be understood as the voting pass rule. The voting permission rule can be flexibly set according to the specific scenario. For example, the voting permission rule is that more than half of the contract council members vote, and the vote is passed). If the number of valid votes meets the preset voting permission rule in the target proposal, the terminal determines that the target proposal is a valid proposal, and the terminal updates the smart contract according to the target contract code in the target proposal; specifically, it includes:

[0089] Step b1: if the number of valid votes meets the voting approval rule corresponding to the target proposal, extract the smart contract address in the target proposal;

[0090] Step b2, extracting the contract source code from the smart contract address, and updating the contract source code to the target contract code in the target proposal, to complete the smart contract update.

[0091] That is, if the number of valid votes meets the preset voting approval rules in the target proposal, the terminal extracts the smart contract address in the target proposal; the terminal extracts the contract source code from the smart contract address, and the terminal replaces the contract source code with the target contract code in the target proposal to complete the smart contract update.

[0092] The embodiment of the present application receives a contract update request, obtains the target proposal associated with the contract update request; broadcasts the target proposal to all nodes of the alliance chain so that each node in the alliance chain votes on the target proposal; receives the votes of each node in the alliance chain, extracts the valid votes of the contract council members corresponding to the target proposal in the vote, and counts the number of valid votes; if the number of valid votes meets the voting approval rules corresponding to the target proposal, the smart contract is updated according to the target contract code in the target proposal. In the embodiment of the present application, the contract council members and voting approval rules corresponding to the target proposal are pre-set, and the number of valid votes corresponding to the contract council members is counted. When the number of valid votes meets the voting approval rules, the smart contract is updated. After the target proposal associated with the smart contract update is broadcast, all members of the alliance chain do not need to vote. At the same time, the voting approval rules corresponding to the target proposal are used to determine whether to perform the smart contract update operation, making the intelligent and reasonable operation management more flexible and reasonable.

[0093] Reference Figure 3 , Figure 3 It is a flowchart of an embodiment of smart contract creation in the smart contract operation management method provided in the embodiments of the present application;

[0094] In some embodiments of the present application, before updating a smart contract in the smart contract operation management method, it is necessary to pre-create a smart contract, including steps 301-304:

[0095] 301, receiving a contract creation request, organizing a smart contract to create a target proposal, wherein the target proposal includes voting approval rules, contract source code, a list of contract council member addresses, and a signature of the proposal initiator.

[0096] The terminal receives a contract creation request, wherein the contract creation request may be actively triggered by the user, for example, the user clicks the "xxx create" button on the terminal display interface to actively trigger the contract creation request; in addition, the contract creation request may also be automatically triggered by the terminal, for example, the triggering condition for the contract creation request is pre-set in the terminal as: when the transaction information is updated; the terminal monitors the changes in the transaction information in the blockchain in real time, and the contract creation request is automatically triggered when the terminal detects that the transaction information in the blockchain is updated.

[0097] After the terminal receives the contract creation request, the terminal obtains the target proposal associated with the contract creation request, where the target proposal includes but is not limited to: contract source code, smart contract address (smart contract address refers to the address information of the storage area of ​​the contract source code), contract council member address list (contract council member address list refers to a list formed by the aggregation of contract council member addresses), voting admission rules (voting admission rules can be understood as voting approval rules, and voting admission rules can be flexibly set according to specific scenarios. For example, the voting admission rule is that more than half of the contract council members vote, and the vote is passed) and the signature of the proposal initiator.

[0098] 302. Broadcast the target proposal to all nodes in the alliance chain, so that each node in the alliance chain votes on the target proposal.

[0099] The terminal broadcasts the target proposal to all nodes in the alliance chain. Other nodes in the alliance chain receive the target proposal and store it in the proposal pool. The target proposal is in a voting state. Users corresponding to other nodes can query the target proposal in the proposal pool. Other nodes vote on the target proposal and send the vote to the terminal. That is, other nodes vote, other nodes obtain the proposal initiator tag in the target proposal, and other nodes feed back the vote to the terminal according to the proposal initiator tag.

[0100] 303, collecting votes of each node in the alliance chain on the target proposal, and counting the number of votes;

[0101] 304. If the number of votes meets the preset consensus rules of the alliance chain, a smart contract is created according to the target proposal.

[0102] The terminal collects votes from each node in the alliance chain on the target proposal, counts the number of votes, and determines whether to create a smart contract based on the number of votes, specifically including:

[0103] Step c1: if the number of votes meets the preset consensus rules of the alliance chain, then extract the voting approval rules, contract source code and contract council member address list in the target proposal;

[0104] Step c2, deploying the voting admission rules and the contract source code to the contract storage area, and generating a smart contract address;

[0105] Step c3, save the contract council member address list to the contract storage area, associate the contract council member address list with the smart contract address and add the proposal initiator's signature to complete the smart contract creation.

[0106] That is, the alliance chain presets its own consensus rules, the terminal collects votes from each node in the alliance chain on the target proposal, the terminal counts the number of votes, and the terminal determines whether the number of votes complies with the preset self-consensus rules in the alliance chain; if the number of votes complies with the preset self-consensus rules in the alliance chain, the terminal extracts the voting approval rules, contract source code and contract council member address list in the target proposal; the terminal deploys the voting approval rules and contract source code to the contract storage area, and generates a smart contract address; the terminal saves the contract council member address list to the contract storage area, the terminal associates the contract council member address list with the smart contract address and adds the signature of the proposal initiator to complete the creation of the smart contract.

[0107] In this embodiment, the contract council members and voting admission rules are set when the smart contract is created. The smart contract operation management can be performed later based on the contract council members and voting admission rules, making the smart contract operation management more flexible and reasonable.

[0108] Reference Figure 4 , Figure 4 It is a flow chart of an embodiment of performing permission verification on the initiator of smart contract creation in the smart contract operation management method provided in the embodiment of the present application.

[0109] In some embodiments of the present application, after receiving a contract creation request in the smart contract operation management method, the terminal performs a permission check on the initiator of the contract creation to determine whether to execute the smart contract creation operation, specifically, including steps 401-403:

[0110] 401, extracting the signature of the proposal initiator in the target proposal, and determining whether the signature of the proposal initiator is included in the preset exception list.

[0111] The terminal has a preset exception list. The preset exception list refers to the information of users who do not have the smart contract update permission. The setting method of the preset exception list can be flexibly set according to the specific scenario. The terminal extracts the signature of the proposal initiator in the target proposal, and the terminal determines whether the signature of the proposal initiator is included in the preset exception list.

[0112] 402. If the preset exception list includes the signature of the proposal initiator, output prompt information indicating that the target proposal is abnormal.

[0113] 403. If the preset exception list does not contain the signature of the proposal initiator, the step of broadcasting the target proposal to all nodes in the alliance chain is performed so that each node in the alliance chain votes on the target proposal.

[0114] In this embodiment, if the preset exception list contains the signature of the proposal initiator, the terminal determines that the initiator corresponding to the signature of the proposal initiator does not have the permission to create a smart contract, and the terminal outputs a prompt message that the target proposal is abnormal, so that the user can view it; if the preset exception list does not contain the signature of the proposal initiator, the terminal determines that the initiator corresponding to the signature of the proposal initiator has the permission to create a smart contract, and the terminal broadcasts the target proposal to all nodes in the alliance chain, so that each node in the alliance chain votes on the target proposal. In this embodiment, setting an exception list can prevent users without operation permissions from creating smart contracts, making the operation and management of smart contracts safer.

[0115] It is understandable that the terminal collects votes from each node in the alliance chain on the target proposal, and after counting the number of votes, if the number of votes does not meet the preset consensus rules of the alliance chain, the signature of the proposal initiator in the target proposal is added to the preset exception list. In this embodiment, when the terminal fails to pass the vote, the terminal adds the signature of the proposal initiator in the target proposal to the preset exception list, which can realize the update of the exception list and make the creation and management of smart contracts more stringent.

[0116] Reference Figure 5 , Figure 5 It is a flow chart of an embodiment of adjusting the state of a smart contract in the smart contract operation management method provided in the embodiment of the present application.

[0117] In some embodiments of the present application, the terminal in the smart contract operation management method can adjust the smart contract state, specifically, including steps 501-504:

[0118] 501, receiving a contract status adjustment request, and obtaining a target proposal associated with the contract status adjustment request;

[0119] 502, broadcasting the target proposal to all nodes in the alliance chain, so that each node in the alliance chain votes on the target proposal;

[0120] 503, receiving votes from each node in the alliance chain, extracting valid votes of the contract council members corresponding to the target proposal in the votes, and counting the number of valid votes;

[0121] 504. If the number of valid votes meets the voting approval rule corresponding to the target proposal, the smart contract is frozen or unfrozen according to the contract status code in the target proposal.

[0122] In this embodiment, the terminal receives a contract status adjustment request, wherein the contract status adjustment request may be a smart contract freeze request and / or a smart contract thaw request. The terminal obtains the target proposal associated with the contract status adjustment request, and broadcasts the target proposal to all nodes in the alliance chain so that each node in the alliance chain votes on the target proposal.

[0123] The terminal receives votes from each node in the alliance chain, extracts the valid votes of the contract council members corresponding to the target proposal in the vote, and counts the number of valid votes; if the number of valid votes does not meet the voting approval rules preset in the target proposal, the terminal does not adjust the smart contract status; if the number of valid votes meets the voting approval rules preset in the target proposal, the terminal freezes or unfreezes the smart contract according to the contract status code in the target proposal.
