These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
In the present disclosure, the terms "include", "arrange", "disposed" and "disposed" are used to mean open-ended inclusion, and mean that there may be additional elements/components/etc. in addition to the listed elements/components/etc.; the terms "first," "second," and the like are used merely as labels, and are not limiting as to the number or order of their objects.
In an exemplary embodiment of the disclosure, an intelligent contract deployment method is provided, which is applied to an intelligent terminal device having a certain storage space, a connectable network and a participating blockchain. Specifically, the intelligent terminal device can be various electronic terminal devices such as a mobile phone, a tablet computer, a notebook computer, a PDA, an ore machine and the like, which have certain storage space, can be connected with a network and participate in a block chain.
Referring to fig. 1, the intelligent contract deployment method may mainly include the following steps:
and step S11, the user sends an intelligent contract deployment instruction to the blockchain network.
And step S12, the block chain network analyzes the deployment instruction.
And step S13, establishing connection with the intelligent contract according to the type in the deployment instruction, and deploying and running the intelligent contract on the blockchain network.
Specifically, a user sends a deployment command to a certain blockchain node in a blockchain network through the terminal device, the node analyzes the deployment command, establishes connection with an intelligent contract according to the type and address in the deployment command after analysis, deploys and operates in the node, and then transmits deployment transactions among all nodes in the blockchain through the network, so that all nodes execute the deployment transactions, and the intelligent contract information is guaranteed to be deployed at all nodes.
In this embodiment, the terminal device is a computer, a contract management module is installed on the computer, the contract management module includes a contract management program, the contract management program provides standard gRPC service, and can communicate and interact with the block link points, and the contract management module is configured to, via a grpcs: /$ host: and $ port/deployment executes the service of the deployment instruction, and through grpcs: /$ host: a service that executes instructions for the port/execute transaction; and meanwhile, the system can be communicated and interacted with the intelligent contract. In the embodiment, a random number UUID generated by a computer is used as a unique account number for logging in by the user, and the account number is saved in a memory after the contract management module is started. The UUID can ensure that any machine-generated identifier is unique at any time.
Specifically, the intelligent contract deployment instruction includes information such as the type, name, and address of the intelligent contract. For example, in this embodiment, a deployment instruction of an out-of-chain intelligent contract is: { "type": "remote", "condensed": "account/v 1", "randheash": "hash (uuid)", "lang": "JAVA", "url": "https: // 192.180.2.23: 9021 "," programhash ": "es 1 fsfgesldpspfmh", "path": jar, "/home/abu/pay," programhasalsgo ": "sha 256" }. In addition, in this embodiment, a deployment instruction of an intra-chain intelligent contract is: { "type": "local", "condensed": "account/v 1", "lang": "JAVA", "bytesload": bytes, "path": "/home/abu/pay. The type refers to the type of the intelligent contract, the value of remote represents the contract outside the chain, and the value of local represents the contract inside the chain; contract is the name of the contract; randhansh is a hash value of an account number of a contract owner logging in the contract management module; lang is the language type of the contract; url is the service address of the contract; the path is a storage path of the contract program; the programhash is the hash value of the contract program; programhashalgo is a designated hash algorithm; bytesload is the contract program bytecode.
The user sends the deployment instruction to the node in the blockchain through the contract management module, and of course, the deployment instruction may also be sent to the node in the blockchain directly through the terminal device, where the deployment instruction includes the type and address of the intelligent contract. If the intelligent contract is stored in the block chain node, namely the intelligent contract is an in-chain contract, the block chain node deploys and runs the intelligent contract in the node, and then the deployment transaction is propagated among all nodes through the internet, so that the intelligent contract is deployed and run on all nodes in the block chain network. If the intelligent contract is stored outside the block chain node, namely the intelligent contract is about an out-of-chain contract, the node sends the deployment command to a contract management module, the contract management module checks the deployment command and establishes communication connection with the intelligent contract, finally the contract management module deploys and runs the intelligent contract on the node of the block chain, and then the deployment transaction is propagated among the nodes through the Internet, so that the intelligent contract is deployed and run on all the nodes in the block chain network. If different nodes in the blockchain network send the same deployment instruction to the contract management module, the contract management module only performs contract deployment to one of the nodes, and then the node with the contract deployed propagates deployment transaction to other nodes without the contract deployed through the network.
Specifically, the contract management module includes a verification of the identity of the user who submitted the deployment instruction and/or a verification of the intelligent contract when verifying the deployment command. The verification of the user identity refers to verifying whether the user is an intelligent contract owner, and the specific process is as follows: calculating a hash value of an account number input when the user logs in the contract management module according to a hash algorithm prograhahalalogo specified in the deployment instruction, comparing the hash value with randhansh in the deployment instruction, if the hash value is the same as the randhansh, the user is an owner of the intelligent contract to be deployed, and if the hash value is different from the randhansh, the user is not the owner of the intelligent contract to be deployed, and then terminating the deployment of the intelligent contract.
The verification of the intelligent contract means that whether the intelligent contract is modified is verified, and the specific process is as follows: reading the intelligent contract file to be deployed according to url and path in the deployment instruction, then calculating the hash value of the intelligent contract file according to a hash algorithm prograhashogo specified in the deployment instruction, comparing the hash value with the prograhash of the intelligent contract in the deployment instruction, if the hash value is the same as the hash value, the verification is passed, namely the contract file is not modified, and if the hash value is different from the hash value, the deployment is terminated. In this embodiment, the intelligent contract is deployed only after the user identity and the intelligent contract verification pass.
And when in deployment, the contract management module establishes a communication channel with the intelligent contract by using the gRPC, starts an intelligent contract program under a path according to a language type specified by lang in the deployment instruction, such as Java, Java-jar. Further, if success is not established within a set time while the contract management module establishes a communication connection with the intelligent contract, the contract deployment is terminated to prevent unlimited processing. For example, if the set communication establishment time is 30 seconds, the contract management module does not establish a communication connection with the intelligent contract within 30 seconds, that is, the contract deployment is terminated.
In particular, an intra-chain contract is a contract stored in each node in a blockchain network, which is exposed externally, and the contents of which can be obtained by anyone who has access to the blockchain network, and therefore it is not private, but because it is public, the contract can be made clearly known once it is modified, and because of the characteristics of the blockchain, the intelligent contract stored in the blockchain network is also not easily modified. The external contract is an intelligent contract stored outside the blockchain network, the intelligent contract is connected with the blockchain network through the contract management module and is deployed and operated in the blockchain network, the external contract is a privacy contract which does not show external public, the privacy of a core algorithm, core logic, capital assets and the like of an owner can be effectively protected, meanwhile, in order to prevent the content of the intelligent contract from being modified, an auditing mechanism is added when the intelligent contract is deployed, whether the intelligent contract is modified or not can be audited, if the intelligent contract is modified, the deployment cannot be carried out, and therefore the uniqueness and the safety of the intelligent contract are guaranteed.
By the intelligent contract deployment method, not only can intra-chain contracts stored in the blockchain network be deployed in the blockchain network, but also extra-chain contracts stored outside the blockchain network can be deployed in the blockchain network, and the uniqueness and the safety of the intelligent contracts are ensured while the privacy of the intelligent contracts are protected.
In addition, in the exemplary embodiment of the disclosure, an intelligent contract execution method is further provided, which is applied to an intelligent terminal device with a certain storage space, a connectable network and a participating blockchain. Specifically, the intelligent terminal device can be various electronic terminal devices such as a mobile phone, a tablet computer, a notebook computer, a PDA, an ore machine and the like, which have certain storage space, can be connected with a network and participate in a block chain.
Referring to fig. 2, the intelligent contract execution method includes the following steps:
and step S21, the user sends an execution instruction to the blockchain network through the intelligent terminal equipment.
In this embodiment, the intelligent terminal device is a computer, a contract management module is installed on the computer, the contract management module includes a contract management program, the contract management program provides standard gRPC service, and can communicate and interact with block link nodes, and the contract management module is configured to, through a grpcs: /$ host: the $ port/deployment performs the service of deploying instructions, through grpcs: /$ host: the port/execute accepts the service of transaction execution; and meanwhile, the intelligent contract can be communicated and interacted with.
The execution instruction comprises the name of the intelligent contract to be executed, an execution method and the parameter of the execution method. One execution instruction in this embodiment, for example, is: { "constrained": "account/v 1", "invoke": [ "query", "zhangsan" ] }. The meaning is as follows: and executing the intelligent contract with the name of account/v1, wherein the executed method is invoke, and the parameter of the method is query/zhangsan.
Step S22, a certain node in the block chain network analyzes the execution instruction, and checks whether the intelligent contract in the execution instruction is deployed in the block chain network, if not, the execution instruction is terminated, if so, the type of the deployed intelligent contract is checked, if so, the intelligent contract is operated and processed in the node according to the execution instruction and the established logic of the intelligent contract; and if the intelligent contract is an out-of-chain contract, sending the execution instruction to a contract management module.
Step S23, after receiving the execution instruction, the contract management module finds a deployed intelligent contract according to the contract name in the execution instruction, and calculates a hash value of the intelligent contract, where the algorithm is a hash algorithm included in the instruction for deploying the intelligent contract when the intelligent contract is deployed, and then compares the hash value of the intelligent contract when the intelligent contract is deployed as a calculation result, and if the two are different, it means that the intelligent contract is modified after being deployed, the execution is terminated, and if the two are the same, the execution instruction and the predetermined logic of the intelligent contract are executed.
The execution instruction sent by the user to the block chain network firstly reaches a certain node in the block chain network, and after the node analyzes and verifies the execution command, the execution command is propagated to other nodes in the block chain through the Internet to execute the transaction.
By the contract execution method, not only can the intra-chain contract stored in the block chain network be executed in the block chain network, but also the out-of-chain contract stored outside the block chain network can be executed in the block chain network, so that the uniqueness and the safety of the intelligent contract are ensured while the privacy of the intelligent contract is protected.
In addition, in the exemplary embodiment of the disclosure, an intelligent contract management device is also provided, which is used for deploying and/or executing the intelligent contract in the block chain network. The intelligent contract management device comprises: the contract management system comprises a contract storage module, a contract management module and a login module. Wherein:
the contract storage module is configured to store intelligent contracts, the intelligent contracts belong to private contracts and do not indicate the private contracts, and the privacy disclosure problem caused by the public of the intelligent contracts is avoided. And the contract management module comprises a communication unit and a verification unit. The communication unit provides standard gRPC service, and can establish communication connection between the contract management module and the blockchain network, and also can establish communication connection between the contract management module and the intelligent contract. The verification unit is used for verifying the deployment instruction and the execution instruction, verifying the identity of a user submitting the deployment instruction when the deployment instruction is verified, verifying whether the user is an owner of the intelligent contract, and meanwhile verifying the intelligent contract pointed by the deployment instruction and verifying whether the intelligent contract pointed by the deployment instruction is modified; when the execution instruction is verified, the intelligent contract pointed by the execution instruction is checked, and whether the intelligent contract pointed by the deployment instruction is modified or not is verified. And the logging module is configured for allowing users to log in the contract management module by using account numbers, the account number of each user is unique, and the account number of the user can be cached in the logging module after logging in for subsequent verification.
