The application provides an intelligent contract processing method. Referring to fig. 4, fig. 4 is a schematic flowchart of an intelligent contract processing method according to an embodiment of the present application. The intelligent contract processing method comprises the following steps:
401. the block chain management equipment acquires a target intelligent contract processing request triggered by a target user;
specifically, the blockchain management device may obtain login information of the target user when the target user logs in, and determine whether the user type of the target user is a trial type according to the login information; and when the user type of the target user is a trial type, the block chain management equipment sends out an intelligent contract trial prompt. For example, the blockchain management device may control display of a smart contract trial prompt on a front-end page of the blockchain management device for enabling experience with the smart contract service. Therefore, the user can learn to experience the intelligent contract service through the block chain management equipment according to the trial prompt of the intelligent contract.
The target user can trigger the target intelligent contract processing request by operating the front-end page of the block chain management equipment at the terminal. The blockchain management device may then obtain the target intelligent contract processing request.
The intelligent contract processing request comprises a user identification of a target user, request content and configuration parameters corresponding to the request content. The request content may specifically include, but is not limited to, any one of request to create a smart contract, deploy a smart contract, invoke a smart contract, and view a smart contract.
402. When the user type of the target user is a trial user, the block chain management equipment generates a target intelligent contract trial instruction according to the target intelligent contract processing request;
the block chain management device can judge whether the user type of the target user is a trial user according to the user identification in the target intelligent contract processing request. And when the target user is a trial user, generating a target intelligent contract trial instruction according to the target intelligent contract processing request. The target intelligent contract generation instructions are for instructing the trial node to process the target intelligent contract processing request.
403. The block chain management equipment sends a target intelligent contract trial instruction to a first node, wherein the first node is one trial node in a plurality of trial nodes with trial block chains running in a block chain system;
it will be appreciated that the blockchain management device may send the target intelligent contract trial instruction to any one of the trial nodes. For example, the target intelligent contract processing request is to create an intelligent contract on the trial blockchain, and after the first node creates the intelligent contract on the trial blockchain, the rest of the trial nodes may also simultaneously create the intelligent contract. That is, one of the trial nodes processes the target intelligent contract processing request, and the remaining trial nodes may simultaneously process the target intelligent contract processing request.
Specifically, the blockchain system may determine the first node according to the load of each trial node, so that the load of each node may be balanced.
In an optional embodiment, a secure channel is established between the blockchain management device and the blockchain system, and the blockchain management device sends the target intelligent contract trial instruction to the trial node through the secure channel.
Specifically, key negotiation is performed in advance between the blockchain management device and each node of the blockchain system, and a data encryption mode and a corresponding decryption mode are agreed. The block chain management equipment can encrypt the target intelligent contract trial instruction by using an agreed data encryption mode, send the encrypted target intelligent contract trial instruction to a trial node in the block chain system, and decrypt the received target intelligent contract trial instruction by using an agreed decryption mode by using the trial node to obtain the decrypted target intelligent contract trial instruction. Thus, although the trial service is provided for the trial user, the user can experience a safe data transmission mode, and the trial experience is better.
404. The first node processes the target intelligent contract processing request by utilizing the trial block chain according to the target intelligent contract trial instruction.
For example, when the target intelligent contract processing request is to create an intelligent contract, the first node creates a new intelligent contract in the trial blockchain according to the target intelligent contract trial instruction, and each trial node creates a new intelligent contract in the trial blockchain according to the target intelligent contract trial instruction. When the target intelligent contract processing request is to invoke an intelligent contract, the first node invokes a corresponding intelligent contract in the trial blockchain according to the intelligent contract identifier in the first intelligent trial contract instruction, and each trial node invokes a corresponding intelligent contract in the trial blockchain according to the intelligent contract identifier in the first intelligent trial contract instruction. When the target intelligent contract processing request is to check the intelligent contracts, the first node checks the corresponding intelligent contracts in the trial blockchain according to the intelligent contract identifications in the first intelligent trial contract instruction, and each trial node checks the corresponding intelligent contracts in the trial blockchain according to the intelligent contract identifications in the first intelligent trial contract instruction.
When the user type of the target user is not the trial user, the block chain management device acquires a private block chain identifier contained in the target intelligent contract processing request, the private block chain identifier is obtained according to user selection operation, the user can select a private block chain on a front end page of the block chain management device, and the block chain management device acquires the block chain identifier of the private block chain selected by the user. And the block chain management equipment generates an intelligent contract processing instruction according to the target intelligent contract processing request, and sends the intelligent contract processing instruction to a private node where a private block chain corresponding to the private block chain identifier is located, wherein the private node is used for processing the target intelligent contract processing request by utilizing the private block chain.
According to the intelligent contract processing method, the block chain management equipment acquires a target intelligent contract processing request triggered by a target user; when the user type of the target user is a trial user, the block chain management equipment generates a target intelligent contract trial instruction according to the target intelligent contract processing request; and the block chain management equipment sends the target intelligent contract trial instruction to a trial node in the block chain system, wherein the trial node runs a trial block chain, and the trial node is used for processing the target intelligent contract processing request by utilizing the trial block chain according to the target intelligent contract trial instruction. In this way, the user can request the blockchain management device to create an intelligent contract, deploy the intelligent contract, call the intelligent contract and view the created intelligent contract on the blockchain system by sending the target intelligent contract processing request, and the processing mode of the intelligent contract is richer.
In an optional embodiment, when the request type of the target intelligent contract processing request is a calling contract type, the blockchain management device acquires the trigger frequency of the target user for triggering the intelligent contract processing request for calling the contract type; when the trigger frequency is less than or equal to the preset frequency, the block chain management device generates a target intelligent contract trial instruction according to the target intelligent contract processing request, and the first node is used for calling an intelligent contract corresponding to the target intelligent contract processing request from the trial block chain according to the target intelligent contract trial instruction. When the trigger frequency is greater than the preset frequency, the block chain management device cannot process the target intelligent contract processing request and cannot generate a target intelligent contract trial instruction.
The block chain management device can trigger the triggering times of the intelligent contract processing request for calling the contract type by the target user in the preset time length, judge whether the triggering times are smaller than or equal to the product of the preset time length and the preset frequency, judge that the triggering frequency is smaller than or equal to the preset frequency if the triggering times are smaller than or equal to the product of the preset time length and the preset frequency, and judge that the triggering frequency is larger than the preset frequency if the triggering times are not larger than the preset frequency.
Thus, the number of times the trial user invokes the smart contract can be limited. Because a plurality of trial users need to experience the intelligent contract service through limited trial nodes, the times of calling the intelligent contract by each trial user are limited, and the load of each trial node can be reduced, so that the trial experience of each trial user is better, and the user experience of calling the intelligent contract by each user at each time is improved although the times of calling the intelligent contract by each trial user is reduced.
In an optional embodiment, when the request type of the target intelligent contract processing request is a create contract type, the blockchain management device acquires the accumulated triggering times of the target user triggering the intelligent contract processing request of the create contract type; when the accumulated triggering times are less than or equal to preset times, the block chain management device generates a target intelligent contract trial instruction according to the target intelligent contract processing request, and the first node is used for creating a target intelligent contract in the trial block chain according to the target intelligent contract trial instruction. And when the triggering frequency is greater than the accumulated triggering times, the block chain management equipment cannot process the target intelligent contract processing request and cannot generate a target intelligent contract trial instruction.
Thus, there is a limit to the number of smart contracts that can be created by each trial user. Therefore, the situation that one user creates too many intelligent contracts and occupies too much resources of trial nodes to influence the user experience of other user bodies can be avoided.
In an optional embodiment, the blockchain management device obtains the created duration of each intelligent contract created in the trial blockchain; the block chain management equipment sends a freezing instruction to a second node, wherein the freezing instruction is used for indicating the second node to freeze an intelligent contract with the created duration exceeding the preset duration, and the second node is one trial node in the plurality of trial nodes. This also reduces the load on the trial nodes.
Based on the above embodiments, in some embodiments, the blockchain management device may further save the request type triggered by the target user as a first intelligent contract processing request for creating a contract type, where the first intelligent contract processing request is used for requesting to create a first intelligent contract; when the user type of the target user is changed into a formal user and the target user has a private block chain, the block chain management device generates a private intelligent contract creation instruction according to the stored first intelligent contract processing request and sends the private intelligent contract creation instruction to a third node, wherein the third node is one of a plurality of private nodes corresponding to the private block chain, and the third node is used for creating the first intelligent contract in the private block chain according to the intelligent contract creation instruction. Therefore, during the trial period, the data left by the trial node can be synchronized to the private node, so that the user data can be protected better, and the user experience is better.
Specifically, the blockchain management device may store the first intelligent contract processing request in a preset database, where the preset database may be a local database of the blockchain management device, or may be another database accessible by the blockchain management device.
Further, as in the example shown in fig. 5, the blockchain system includes a plurality of private nodes 101'. When the fact that the user type of the target user is changed into a formal user is detected, and the target user has a private block chain, the block chain management device obtains a first state of a first intelligent contract from a trial node through a safety channel between a block chain system and the trial node, generates a private intelligent contract creation instruction according to the first state and a first intelligent contract processing request, and sends the private intelligent contract creation instruction to a third node, wherein the third node is any one of a plurality of private nodes operating with the private block chain. The third node is used for creating the first intelligent contract according to the first private intelligent contract creating instruction and controlling the first intelligent contract to enter the first state. Therefore, the intelligent contract created by the user in the trial blockchain can be migrated to the private blockchain, and the state of the intelligent contract can also be migrated synchronously. Therefore, after the target user becomes a formal user, the block chain management device can also create the same intelligent contract in the private block chain according to the intelligent contract created by the target user during the trial period, and the states of the intelligent contracts are also the same, so that the trial stage and the payment stage can be better connected, and the user experience is better.

a request obtaining module 601, configured to obtain a target intelligent contract processing request triggered by a target user;
an instruction generating module 602, configured to generate a target intelligent contract trial instruction according to the target intelligent contract processing request when the user type of the target user is a trial user;

According to the block chain management device, the block chain management device acquires a target intelligent contract processing request triggered by a target user; when the user type of the target user is a trial user, the block chain management equipment generates a target intelligent contract trial instruction according to the target intelligent contract processing request; and the block chain management equipment sends the target intelligent contract trial instruction to a trial node in the block chain system, wherein the trial node runs a trial block chain, and the trial node is used for processing the target intelligent contract processing request by utilizing the trial block chain according to the target intelligent contract trial instruction. In this way, the user can request the blockchain management device to create an intelligent contract, deploy the intelligent contract, call the intelligent contract and view the created intelligent contract on the blockchain system by sending the target intelligent contract processing request, and the processing mode of the intelligent contract is richer.
