Key terms
Blockchain techniques: the system is a brand new distributed infrastructure and calculation paradigm which uses a block chain type data structure to verify and store data, uses a distributed node consensus algorithm to generate and update data, uses a cryptography mode to ensure the safety of data transmission and access, and uses an intelligent contract consisting of automatic script codes to program and operate the data. Essentially, the system is a shared database, and data or information stored in the shared database has the characteristics of incapability of counterfeiting, whole trace, traceability, openness, transparency, collective maintenance and the like. Based on the characteristics, the blockchain technology lays a solid trust foundation, creates a reliable cooperation mechanism and has wide application prospect.
Intelligent contract: the program running in the block chain system has the characteristics of automatic execution according to the set logic and non-falsification of the execution result.
System contracts: some intelligent contracts built in the blockchain system encapsulate management functions such as rights management, account identity management, etc. that affect the system level. The system contracts are in principle validated by the blockchain administrator to deploy the whole network at the beginning of the network start. If the change upgrade is redeployed during network operation, operations need to be performed by the blockchain administrator with permission from all nodes of the whole network.
The contract method comprises the following steps: defined functions in the smart contracts are declared publicly callable and can be invoked by external programs or other contracts. The successfully deployed contract method has a globally unique address for external program invocation.
The following details, by way of specific example, of a scheme for managing blockchain system contracts using blockchain intelligence contracts in accordance with the present specification.
Example 1
Because the content in the existing blockchain has the characteristic of being unchangeable, the updating of the blockchain system contract generally needs to issue a new contract, which causes the application system to be unable to know the new contract address, and thus the new system contract cannot be directly used. The upgrading process often requires that the blockchain network administrator issue a change description to each node administrator, and the node administrator notifies the application administrator again, and completes the adaptation of the new system contract by modifying and upgrading the application. The process has the advantages of manual participation and multi-role participation, is easy to make errors, and needs to stop and maintain an application system.
Thus, in a scheme for managing blockchain system contracts using blockchain intelligence contracts, a 2-party execution subject is involved, one being a blockchain network and the other being a node or application. Wherein the first component is encapsulated and formed by a blockchain network administrator at 3 stages of a blockchain deployment system contract registration contract service, a system contract release, a system contract update, and the like. The calling system contract registration contract obtains the system contract address, the calling system contract method address, the executing system contract method and other 3 stages, and the second assembly is formed by encapsulation and is executed by the blockchain node or the application program manager. A blockchain network includes a first component, wherein the first component corresponds to a plurality of blockchain nodes and can also support a plurality of application programs; a blockchain node or application includes a second component; the blockchain node or the application program calls the system contract registration contract query and call system contracts and methods thereof through the second component.
For blockchain networks:
in a system contract registration contract deployment stage, firstly, a system contract registration contract is created by a first component built in a blockchain network, wherein the system contract registration contract is a public intelligent contract specially used for recording the blockchain system contract and the address of a method thereof, and the method for registering the system contract comprises at least one of registering, updating and inquiring the system contract; the contract is then deployed onto the blockchain.
In the system contract releasing stage, the block chain network manager packages and compiles the written system contracts and the method thereof and deploys the system contracts to the block chain. Because the content of the blockchain network has the characteristic of being unchangeable, the updating of the blockchain intelligent contract generally needs to issue a new contract, so that an application system cannot know a new contract address, and thus cannot directly use the new system contract. Therefore, when a new system contract is issued, the system contract registration contract is required to be called to register the newly issued system contract, namely, the address of the system contract and the address of the method thereof in the blockchain network are received; searching whether the addresses of the system contracts and the methods thereof exist in the blockchain network, and if not, storing the addresses of the system contracts and the methods thereof into the blockchain.
In the system contract updating stage, the system contracts and the method thereof which are written are packaged and compiled by a blockchain network administrator and then deployed to a blockchain; then, receiving the address of the original system contract and the address of the new system contract and the method thereof in the block chain network; searching whether the original system contract address exists in the blockchain network, if so, replacing the original system contract and the method address thereof with the new system contract and the method address thereof, and storing the new system contract and the method address thereof into the blockchain.
For blockchain nodes or applications:
the blockchain node or the application program needs to grasp the latest address of the system contract and the method thereof in the process of calling and executing the system contract method, and the process needs to call the system contract registration contract to complete. Firstly, calling a query method of a system contract registration contract to acquire all callable system contract addresses in a blockchain; then, the address of the system contract method is obtained according to the system contract address required by the blockchain node or the application program; and sending the address of the system contract and the address of the method thereof to a blockchain node or an application program so that the blockchain node or the application program can call the method of the system contract according to the address of the system contract and the address of the method thereof.
In summary, the system for managing blockchain system contracts can be formed based on the technical scheme, and the system comprises a first component and a second component, wherein,
the first component creates a system contract registration contract and deploys the system contract registration contract to a blockchain, acquires the system contract and a method address of the system contract deployed to the blockchain, and calls the system contract registration contract to complete registration or update of the system contract and the method thereof; the second component is arranged in a node or an application program, and the system contract and the method address thereof are acquired through a system contract registration contract;
The first component sending the system contract and its method address to the blockchain; a plurality of the second components request the system contract and its method address from the blockchain.
Example two
Referring to fig. 1, a schematic diagram of steps of a method for managing a blockchain system contract according to an embodiment of the present disclosure is shown, where an execution subject of the method may be a blockchain system side, and an executor is a blockchain network administrator, that is, defined as a first component in the present disclosure; the first component may specifically be a service program or an electronic device such as a terminal. The method creates a system contract registration contract and deploys the system contract registration contract to a blockchain, the system contract registration contract method comprises at least one of registering, updating and inquiring the system contract, and deploys the written system contract registration contract to the blockchain network, and the method comprises the following steps:
step 101: a system contract registration contract is created and deployed to the blockchain, the system contract registration contract being an intelligent contract that records the blockchain system contract and its method addresses to obtain the method addresses of the system contract registration contract for system contract registration, updating and querying.
Optionally, as shown in fig. 3, the method for processing the registration transaction of the system contract registration contract includes:
step 121: receiving an address of a system contract and a method thereof;
step 122: addresses of the system contracts and methods thereof are stored to the blockchain.
Optionally, as shown in fig. 4, the method for updating the system contract registration contract includes:
step 131: receiving an address of an original system contract and an address of a new system contract and a method thereof;
step 132: replacing the address of the original system contract and the method thereof with the address of the new system contract and the method thereof, and storing the address to the blockchain.
Optionally, as shown in fig. 5, the query transaction processing method of the system contract registration contract includes:
step 141: querying and feeding back all the system contract addresses registered in the blockchain and capable of being called;
step 142: and inquiring and feeding back addresses of all contract methods according to the system contract addresses requested by the block connection points or the application programs.
Step 102: and after the system contract is issued and deployed to the block chain, the address of the system contract and the address of the method thereof in the block chain are acquired.
Because the content of the blockchain network has the characteristic of being unchangeable, the updating of the blockchain intelligent contract needs to issue a new contract, so that an application system cannot know a new system contract address, and thus cannot directly use the new system contract. The system contract registration contract is used as public intelligent contract to issue the latest system contract and its address for the whole blockchain network to be used by the blockchain node or application program needing to call the system contracts.
It should be understood that, because the system contracts take on some common actions in the blockchain network, such as authority management of accounts, identity management of accounts, etc., when the system contracts are used for blockchain system management, the blockchain nodes or applications can complete hot update without restarting, i.e. dynamically issue update codes, and can synchronize system configuration without restarting devices or applications. The system contract function and configuration can be the same immediately by completing the blockchain ledger data synchronization after a new node or application program is added. Therefore, the introduction of the system contract registration contract solves the problem of automatic perception of new release and update of the system contract by the blockchain node or the application program, namely, the function of acquiring the latest address of the system contract and the method thereof can be realized only when the calling function of the system contract registration contract is built in the blockchain node or the application program.
Step 103: when the system contracts as a new contract, calling the system contract registration contract to register as the new contract;
step 104: when the system contracts about existing contracts, the system contract registration contract is called to update the existing contracts to new contracts.
Alternatively, referring to fig. 2, a schematic diagram of steps of a method for managing a blockchain system contract according to an embodiment of the present disclosure may be provided, where an execution subject of the method may be a blockchain system side, and an executor is a blockchain network administrator, which is defined as a first component in the present disclosure; the first component may specifically be a service program or an electronic device such as a terminal. The method creates a system contract registration contract and deploys the system contract registration contract to a blockchain, and the system contract registration contract method comprises at least one of registering, updating and inquiring the system contract, and deploys the written system contract registration contract to the blockchain network. Wherein, the liquid crystal display device comprises a liquid crystal display device,
the registration transaction processing method of the system contract registration contract is shown in fig. 3, and includes:
step 121: receiving an address of a system contract and a method thereof;
step 122: addresses of the system contracts and methods thereof are stored to the blockchain.
The update transaction processing method of the system contract registration contract is shown in fig. 4, and includes:
step 131: receiving an address of an original system contract and an address of a new system contract and a method thereof;
step 132: replacing the address of the original system contract and the method thereof with the address of the new system contract and the method thereof, and storing the address to the blockchain.
The query transaction processing method of the system contract registration contract is shown in fig. 5, and includes:
step 141: querying and feeding back all the system contract addresses registered in the blockchain and capable of being called;
step 142: and inquiring and feeding back addresses of all contract methods according to the system contract addresses requested by the block connection points or the application programs.
Step 111: and after the system contract is issued and deployed to the block chain, the address of the system contract and the address of the method thereof in the block chain are acquired.
Because the content of the blockchain network has the characteristic of being unchangeable, the updating of the blockchain intelligent contract needs to issue a new contract, so that an application system cannot know a new system contract address, and thus cannot directly use the new system contract. The system contract registration contract is used as public intelligent contract to issue the latest system contract and its address for the whole blockchain network to be used by the blockchain node or application program needing to call the system contracts.
It should be understood that, because the system contracts take on some common actions in the blockchain network, such as authority management of accounts, identity management of accounts, etc., when the system contracts are used for blockchain system management, the blockchain nodes or applications can complete hot update without restarting, i.e. dynamically issue update codes, and can synchronize system configuration without restarting devices or applications. The system contract function and configuration can be the same immediately by completing the blockchain ledger data synchronization after a new node or application program is added. Therefore, the introduction of the system contract registration contract solves the problem of automatic perception of new release and update of the system contract by the blockchain node or the application program, namely, the function of acquiring the latest address of the system contract and the method thereof can be realized only when the calling function of the system contract registration contract is built in the blockchain node or the application program.
Step 112: when the system contracts as a new contract, calling the system contract registration contract to register as the new contract;
step 113: when the system contracts about existing contracts, the system contract registration contract is called to update the existing contracts to new contracts.
Referring to fig. 6, a schematic diagram of method steps for managing a blockchain system contract according to an embodiment of the present disclosure is shown, where an execution subject of the method may be a blockchain node or an application side, and the method is defined as a second component in the present disclosure; the second component is placed in a blockchain node or application, comprising the steps of:
