Referring to fig. 1, fig. 1 is a system schematic diagram of a contract deployment apparatus according to an embodiment of the present application. The system is a blockchain network system, and can comprise a plurality of terminals as user nodes, wherein one terminal is an administrator node, and the blockchain network is used for receiving a contract deployment request of a target user node in the blockchain network, wherein the contract deployment request comprises at least one target contract to be deployed by the target user node; acquiring an agent contract deployed by an administrator node, the agent contract for deploying a target contract in a blockchain network according to a contract deployment request; acquiring a time threshold for contract deployment in a blockchain network from a proxy contract; acquiring the number of times to be deployed of contract deployment of a target user node in a blockchain network currently based on the number of target contracts; determining a number of deployed times for contract deployment in the blockchain network based on the proxy contract; and if the sum of the deployment times of the times to be deployed and the deployed times does not exceed the time threshold, deploying the target contract in the blockchain network through the proxy contract.

The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.

The present embodiment will be described from the perspective of a contract deployment apparatus, which may be integrated in a terminal device, and the terminal device may include a smart phone, a notebook computer, a tablet computer, a personal computer, and the like.

The embodiment of the present application provides a method for deploying contracts in a blockchain, which may be executed by a processor of a terminal, as shown in fig. 2, and the specific flow of the method for deploying contracts in a blockchain mainly includes steps 201 to 206, which are described in detail below:

step 201, receiving a contract deployment request of a target user node in a blockchain network, wherein the contract deployment request is used for indicating that at least one target contract to be deployed of the target user node is deployed in the blockchain network.

In the present embodiment, a contract is a digitally defined protocol that includes providing, verifying and executing the digital form, and is a contract that replaces legal language record terms with a computer language and is automatically executed by a program. A contract may be considered a digitized version of a traditional contract, running on a blockchain network, automatically executed by a program. Wherein the target contract is a contract for the target user node to be deployed in the blockchain network. In addition, the proxy contracts mentioned in step 202 include the number of times the contracts have been deployed by the respective user nodes in the blockchain network and the total number of times the contracts can be deployed in the blockchain network, as well as the proxy transaction method of the respective contracts deployed in the blockchain network, the proxy contracts being generated by the administrator node deployment in the blockchain network.

In the embodiment of the application, when the target user node wants to make the establishment of the protocol with other user nodes effective, the target user node can deploy a contract for recording the protocol in the blockchain network, so that the user nodes of both parties of the protocol can execute the protocol.

In this embodiment of the present application, the target user node may be one of the user nodes included in the blockchain network, and after the blockchain network receives the contract deployment request of the target user node, it needs to determine whether the target user node has the authority to perform contract deployment in the blockchain network. If yes, further judging the contract deployment times.

In the embodiment of the application, if the target user node which wants to perform contract deployment does not have the authority to perform contract deployment in the blockchain network, in order to enable the target user node to deploy a target user in the blockchain network, a node addition transaction can be initiated by an administrator node, so that a target user identifier can deploy a target contract in the blockchain network. After the step 201 "receiving the contract deployment request of the target user node in the blockchain network" at this time, the method may further include:

If the target user node does not have contract deployment authority for performing contract deployment in the blockchain network, initiating node addition transaction by an administrator node, wherein the node addition transaction is used for enabling the target user node to have the contract deployment authority;

and executing uplink processing on the node adding transaction to trigger the blockchain network to set contract deployment authority for the target user node according to the node adding transaction.

In the embodiment of the application, when the target user node can perform contract deployment in the blockchain network, the target user node can directly have the authority to perform contract deployment in the blockchain network, and then can continue to perform contract deployment in the blockchain network.

Furthermore, the target user node may still not have contract deployment rights, but may simply deploy the target contract in the blockchain network without rights to deploy other contracts in the blockchain network.

In an embodiment of the present application, the contract deployment request may include a contract identifier (contract name, contract number, etc.) and contract specific content (i.e., a code for deploying a contract) of a target contract to be deployed by the target user node in the blockchain network.

In the embodiment of the present application, the target user node performing contract deployment may be one or more, and if the target user node is more than one, the "receiving the contract deployment request of the target user node in the blockchain network" in step 201 may be: if the target user nodes are a plurality of, a contract deployment request of at least one target user node in the blockchain network is received, wherein the contract deployment request comprises private keys of all target user nodes in the blockchain network and node identifiers. At this point, step 205 "determine the number of deployed times of contract deployment in the blockchain network based on the proxy contract" may be: determining the deployed times of contract deployment for each target user node in the blockchain network based on the proxy contracts, step 206 "if the sum of the deployment times of the to-be-deployed times and the deployed times does not exceed the time threshold, deploying the target contracts in the blockchain network through the proxy contracts" may be: if the sum of the deployed times corresponding to each target user node and the to-be-deployed times does not exceed the time threshold, deploying the target contract through the proxy contract based on the private key of each target user node in the blockchain network and the node identification.

Step 202, obtaining an agent contract deployed by an administrator node of a blockchain network, the agent contract for deploying a target contract in the blockchain network according to a contract deployment request.

In this embodiment, before the agent contract is acquired, the agent contract needs to be deployed in the blockchain network by an administrator node, where the administrator node may be one of the user nodes or may be independent of the user nodes, that is, before the step 202 of acquiring the agent contract deployed by the administrator node, further includes:

determining an administrator node among a plurality of user nodes included in a blockchain network;

receiving a contract first deployment request of first contract deployment of a user node in a blockchain network through an administrator node;

an agent contract is deployed in a blockchain network by an administrator node based on a contract first deployment request.

In the embodiment of the present application, the determination method of the administrator node is not limited, and the administrator node may be a user node specified by a related technician in the blockchain network, or may be a user node selected by a predetermined rule (for example, multi-sign authority management, network resource is best, etc.). The number of manager nodes may be one or more without limitation.

In the embodiment of the application, the first contract deployment request is a contract deployment request sent when one of all user nodes in the blockchain network performs contract deployment for the first time, and after an administrator node receives the request, an agent contract is deployed in the blockchain network. To limit the number of times of contract deployment, a threshold of the number of times of contract deployment in the blockchain network may be set in the proxy contract, and the number of deployed times of contract deployment in the blockchain network is recorded in real time. In addition, in order to enable the user node to perform contract deployment in the blockchain network through the proxy contract, a method for performing contract deployment may be further set in the proxy contract.

In the embodiment of the application, in order to reduce the deployment of the proxy contracts and reduce the resource occupation of the proxy contracts, the blockchain network can only have one proxy contract, all user nodes for deploying the contracts acquire the frequency threshold and the deployed frequency through one proxy contract, and all the user nodes call a contract deployment method in one proxy contract to deploy the contracts.

In the embodiment of the present application, in order to avoid frequent use of proxy contracts, each user node performing contract deployment may correspond to one proxy contract, that is, when each user node first performs contract deployment in a blockchain network, an administrator node deploys the proxy contract corresponding to the user node in the blockchain network, and when each user node deploys a contract in the blockchain network, the user node performs frequency judgment through the corresponding proxy contract and invokes a contract deployment method.

In one embodiment of the present application, the administrator node may deploy a proxy contract each time the user node performs contract deployment in the blockchain network.

Step 203, obtaining a threshold of times of contract deployment in the blockchain network in the proxy contract.

In this embodiment of the present application, the maximum number of times that each user node can perform contract deployment in the blockchain network, that is, the first time threshold, may be set in the proxy contract, and before the step 203 of acquiring the number of times threshold for performing contract deployment in the blockchain network in the proxy contract, the method may further include: receiving, by an administrator node, first time count constraint information sent by a target user node, the first time count constraint information including a first time count threshold for contract deployment of the target user node in a blockchain network; the first time count threshold is set in the proxy contract by the administrator node. At this time, the step 203 "acquiring the threshold number of times of contract deployment in the blockchain network in the proxy contract" includes: the first time threshold value of contract deployment of the target user node in the blockchain network is obtained in the proxy contract.

In the embodiment of the present application, the first time number threshold for each user node performing contract deployment in the blockchain network may be determined by the user node itself, and then the first time number limitation information is sent to the administrator node, so that the administrator node obtains the first time number threshold.

In the embodiment of the application, in order to better manage the contract deployment times of each user node in the blockchain network, the first time number threshold value of each user node can be uniformly set. The first time threshold value corresponding to each user node may be the same or different.

In the embodiment of the present application, the total number of times that all user nodes can perform contract deployment in the blockchain network, that is, the second threshold of times, in a preset time (for example, one day) may be set in the proxy contract, so as to avoid more contracts deployed in the blockchain network. When the number of times threshold is the second number of times threshold, before "obtaining the number of times threshold for performing contract deployment in the blockchain network in the proxy contract" in step 203, the method may further include: the administrator node sets a second time threshold for contract deployment in the blockchain network by the deployable user node in the agent contract, wherein the deployable user node comprises a user node with contract deployment authority in the blockchain network in a plurality of user nodes. At this time, the step 203 "acquiring the threshold number of times of contract deployment in the blockchain network in the proxy contract" may be: a second time threshold for contract deployment of the deployable user node in the blockchain network is obtained in the proxy contract.

Step 204, obtaining the number of times to be deployed of contract deployment of the target user node in the blockchain network based on the number of target contracts.

In the embodiment of the application, since the user node deploys one target contract at a time, that is, the number of target contracts is the same as the number of times to be deployed for which the target user node is about to deploy the contract in the blockchain network, the number of target contracts can be determined according to the contract deployment request, and then the number of target contracts is the number of times to be deployed for the target user node.

Step 205, determining the deployed times of contract deployment in the blockchain network based on the proxy contract.

In the embodiment of the present application, the contract deployment request includes a target node identifier of the target user node in the blockchain network, and when the number threshold is the first number threshold, the deployed number is a first deployed number of times the target user node has deployed a contract in the blockchain network, where the step 205 of determining, based on the proxy contract, the deployed number of times the contract is deployed in the blockchain network may be based on the target node identifier, to obtain, in the proxy contract, the first deployed number of times the target user node is deployed in the blockchain network.

In the embodiment of the present application, when the number of times threshold is the second number of times threshold, the deployed number of times may be the second deployed number of times that contracts have been deployed in the blockchain network within a preset time, and in this case, the "determining the deployed number of times that contracts are deployed in the blockchain network based on the proxy contract" in step 205 may be obtaining the second deployed number of times that the deployable user node performs contracts deployment in the blockchain network within the preset time based on the proxy contract.

Step 206, if the sum of the deployment times of the number of times to be deployed and the deployed number of times does not exceed the time threshold, deploying the target contract in the blockchain network through the proxy contract.

In the embodiment of the present application, if the sum of the number of times to be deployed and the number of times to be deployed does not exceed the number of times threshold, the number of times to be deployed that the target user node performs contract deployment in the blockchain network does not exceed the maximum number of times that the target user node can perform contract deployment in the blockchain network, and the number of times to be deployed that the target user node performs contract deployment at the current moment does not exceed the number of times that the target user node can also perform contract deployment in the blockchain network, which indicates that the target user node can also deploy the target contract in the blockchain network.

In the embodiment of the present application, when the deployed number is the first deployed number, and the number threshold is a first number threshold for performing contract deployment on the target user node in the blockchain network, if the sum of the number to be deployed and the first deployed number of the first deployed number exceeds the first number threshold, it indicates that the target user node cannot currently deploy the target contract in the blockchain network. At this time, in order to avoid that some important contracts of the target user node cannot be deployed in the blockchain network, the administrator node may increase the maximum number of times the target user node can perform contract deployment in the blockchain network, that is, the administrator node may increase the first-time threshold originally set in the proxy contract. In order to enable the target user node to deploy the target contract currently and control the number of times the target user node deploys the contract in the blockchain network, the first time threshold may be changed to a minimum value that allows the target user node to deploy the target contract, which may specifically be:

if the first deployment frequency sum of the to-be-deployed frequency and the first deployed frequency exceeds a first frequency threshold, determining a frequency difference value between the first deployment frequency sum and the first frequency threshold through an administrator node;

Initiating a number of times increment transaction by the administrator node, the number of times increment transaction comprising a number of times difference;

In the embodiment of the present application, in order to accurately record, in real time, the deployed times of contract deployment performed by the target user node in the blockchain network, when the target user node deploys the target contract in the blockchain network, it is indicated that the deployed times of contract deployment performed by the target user node in the blockchain network are changed, and the deployed times need to be updated, and the specific method may be:

the first number of deployments is updated in the proxy contract to a first sum of deployments based on the target node identification.

In the embodiment of the present application, the contract deployment request includes the candidate node identification of the deployable target contract, and the "deploying the target contract in the blockchain network through the proxy contract" in step 206 may be:

acquiring a target node identification of a target user node in a blockchain network according to a contract deployment request;

If the target node identifier belongs to the candidate node identifier, creating a contract deployment method corresponding to the target contract in the proxy contract through an administrator node;

invoking a contract deployment method in the proxy contract through the target user node;

a contract-based deployment method deploys a target contract in a blockchain network.

In this embodiment of the present application, after the target contract is deployed in the blockchain network, the user node having the authority to invoke the target contract may invoke the target contract to complete a series of functions, and the user node having the authority to invoke the target contract needs to obtain the contract address of the target contract in the blockchain network, so, after the deployment of the target contract is completed, the contract address of the target contract needs to be sent to the user node having the authority to invoke the target contract, where the specific contract deployment request includes the identity of the invoking node of the invoking user node that may invoke the target contract in the blockchain network, where step 206 "after deploying the target contract in the blockchain network through the proxy contract" may further include: and feeding back the target contract address of the target contract in the blockchain network to the calling user node according to the calling node identification so that the calling user node calls the target contract according to the target contract address, wherein one target contract corresponds to one target contract address.

In the embodiment of the present application, in order to avoid that a user node having authority to invoke a target contract makes multiple useless invocations, so that network resources are wasted, the number of invocations of each user node having authority to invoke the target contract may be limited, that is, the maximum invocable number of invocations of the target contract may be included in the contract deployment request, which may specifically be:

and if the sum of the calling times is smaller than or equal to the maximum calling times, realizing that the target calling user node calls the target contract.

All the above technical solutions may be combined to form an optional embodiment of the present application, which is not described here in detail.

According to the method for deploying contracts in the blockchain network, when a target user node wants to deploy a target contract in the blockchain network, the deployed times of contract deployment in the blockchain network and the times to be deployed of contract deployment currently want to be performed by the target user node are judged through the proxy contract, and the target contract can be further deployed through the proxy contract only if the times of contract deployment in the blockchain network are not exceeded by the threshold value of times of contract deployment in the blockchain network, so that the times of contract deployment of the user node in the blockchain network is limited, a plurality of blockchain contracts with the same functions in the blockchain network can be effectively reduced, and contract confusion and invalid contract overmuch in the blockchain network are avoided.

Referring to fig. 3, fig. 3 is another flow chart of a method for deploying contracts in a blockchain provided in an embodiment of the present application. The specific flow of the method can be as follows:

determining an administrator node in a user node of a blockchain network, deploying a proxy contract in the blockchain network by the administrator node, recording a first time threshold value of a user node for deploying the contract in the blockchain network and a first deployed time of the deployed contract in the proxy contract, determining that a target user node can deploy the contract in the blockchain network by the first time threshold value, the first deployed time and the current time to be deployed for deploying the contract when a contract deployment request of a user is received, deploying a contract deployment method corresponding to the target contract 1 in the proxy contract and a contract deployment method corresponding to the target contract n, invoking the contract deployment method corresponding to the target contract 1 in the proxy contract by the user node, deploying the user contract 1 in the blockchain network by the contract deployment method corresponding to the target contract n in the proxy contract, and deploying the user contract n in the blockchain network.
