Key terms
Block chaining techniques: the distributed data processing system is a brand new distributed infrastructure and computing paradigm for verifying and storing data by using a block chain type data structure, generating and updating data by using a distributed node consensus algorithm, ensuring the safety of data transmission and access by using a cryptographic mode, and programming and operating data by using an intelligent contract consisting of automatic script codes. In essence, it is a shared database, and the data or information stored in it has the characteristics of being unforgeable, having trace in the whole course, being traceable, being publicly transparent, being maintained collectively, and the like. Based on the characteristics, the block chain 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.
A system contract: some intelligent contracts built into the blockchain system encapsulate management functions that affect the system level, such as rights management, account identity management, etc. The system contract is in principle validated by the blockchain administrator at the initial deployment of the network. If the change upgrade is redeployed during network operation, it needs to be performed by the blockchain administrator with permission from all nodes of the entire network.
The contract method comprises the following steps: the defined function in the intelligent contract is declared as publicly-invokable and can be called by an external program or other contracts. A contract method that is successfully deployed has a globally unique address that can be called by an external program.
The following describes a detailed example of a scheme for managing a blockchain system contract using a blockchain intelligent contract according to the present specification.
Example one
Because the content in the blockchain has the characteristic of being incapable of being changed, the application system cannot know a new contract address and cannot directly use a new system contract due to the fact that the block chain system contract needs to be issued when being upgraded. This upgrade process often requires the blockchain network administrator to issue a change specification to each node administrator, who then notifies the application administrator to complete the adaptation of the new system contract by modifying and upgrading the application. The process has manual participation and multi-role participation, is easy to make errors, and needs shutdown maintenance of an application system.
Thus, in a scheme that uses blockchain intelligent contracts to manage blockchain system contracts, 2-party execution agents are involved, one party being a blockchain network and the other party being a node or application. The first component is formed by encapsulation in 3 stages of deploying system contract registration contract service, issuing system contract, updating system contract and the like in the blockchain, and is executed by a blockchain network administrator. And calling a system contract registration contract to obtain a system contract address, calling a system contract method address, executing a system contract method and the like, packaging to form a second component, and executing by a block link point or an application program administrator. A blockchain network includes a first component, a first component corresponding to a plurality of blockchain nodes and also supporting a plurality of applications; a blockchain node or application comprises a second component; the blockchain node or application invokes a system contract registration contract query and invokes a system contract and methods thereof via the second component.
For blockchain networks:
in the stage of deploying the system contract registration contracts, firstly, a system contract registration contract is created by a first component built in a block chain network, the system contract registration contract is a public intelligent contract which is specially used for recording the block chain system contract and a method address thereof, and the method for registering the system contract comprises at least one of registration, updating and query of the system contract; the contract is then deployed onto the blockchain.
In the stage of issuing the system contract, a block chain network administrator encapsulates and compiles the written system contract and the method thereof and deploys the system contract and the method to a block chain. Because the content of the existing blockchain network has the characteristic of being unchangeable, generally, the upgrading of the blockchain intelligent contract needs to issue a new contract, so that an application system cannot know a new contract address, and a new system contract cannot be directly used. Therefore, when a new system contract is issued, the system contract registration contract is called to register the newly issued system contract, namely, the addresses of the system contract and the method thereof in the block chain network are received; and searching whether the address of the system contract and the method thereof exists in the block chain network, and if not, storing the address of the system contract and the method thereof into the block chain.
In the stage of updating the system contract, the block chain network administrator needs to encapsulate and compile the compiled system contract and the method thereof and then deploy the system contract and the method to the block chain; then, receiving the original system contract address and the address of the new system contract and the method thereof in the block chain network; and searching whether the original system contract address exists in a block chain network, and if so, replacing the original system contract and the method address thereof with the address of the new system contract and the method thereof and storing the new system contract and the method address in the block chain network.
For blockchain nodes or applications:
in the process of calling and executing a system contract method, a blockchain node or an application program needs to master the latest address of the system contract and the method thereof, and the process needs to call a 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 block chain; then, acquiring the address of the system contract method according to the system contract address required by the block chain node or the application program; and sending the addresses of the system contracts and the methods thereof to a block chain node or an application program so that the block chain node or the application program calls the methods of the system contracts according to the addresses of the system contracts and the methods thereof.
In summary, the system for managing the system contract of the blockchain based on the technical solution includes a first component and a second component, wherein,
the first component creates a system contract registration contract and deploys the contract to a block chain, obtains the system contract and a method address thereof deployed to the block chain, and calls the system contract registration contract to complete registration or updating of the system contract and the method thereof; the second component is arranged in a node or an application program, and acquires the system contract and a method address thereof through a system contract registration contract;
the first component sends the system contract and its method address to the blockchain; a plurality of the second components request the system contracts and their method addresses from the blockchain.
Example two
Referring to fig. 1, a schematic diagram of steps of a method for managing a blockchain system contract provided in an embodiment of the present specification is provided, 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 specification; 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 the blockchain, the system contract registration contract method comprises at least one of registration, updating and query of the system contract, and the written system contract registration contract is deployed 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, so as to obtain the method addresses of the system contract registration contract for system contract registration, updating and querying.
Optionally, the method for processing a registration transaction of a 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: storing addresses of the system contract and its methods to the blockchain.
Optionally, the update transaction processing method of the system contract registration contract is shown in fig. 4 and includes:
step 131: receiving an original system contract address and an address of a new system contract and a method thereof;
step 132: and replacing the original system contract and the method address thereof with the address of the new system contract and the method thereof, and storing the new system contract and the method thereof in the block chain.
Optionally, the query transaction processing method of the system contract registration contract is shown in fig. 5, and includes:
step 141: inquiring and feeding back all the system contract addresses which are registered in the block chain and can be called;
step 142: and inquiring and feeding back the 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 issuing a system contract and deploying the system contract to the block chain, acquiring the address of the system contract and the address of the method thereof in the block chain.
Because the content of the existing blockchain network has the characteristic of being unchangeable, generally, the upgrading of the blockchain intelligent contract needs to issue a new contract, so that an application system cannot know the address of the new system contract, and the new system contract cannot be directly used. The system contract registration contract has the function that after the system contract and the method thereof are deployed in the blockchain network and are endowed with corresponding storage addresses, the system contract registration contract is used as a public intelligent contract and issues the address of the latest system contract and the method thereof to the whole blockchain network so as to be used by the blockchain link points or application programs needing to call the system contracts.
It should be understood that, since the system contract undertakes some common behaviors in the blockchain network, such as the authority management of the account, the identity management of the account, and the like, when the blockchain contract is used for blockchain system management, the blockchain node or the application program can complete hot update without restarting, that is, update codes are dynamically issued, and the system configuration can be synchronized without restarting a device or the application program. And after a new node or application program is added, the block chain ledger data synchronization is completed, and the same system contract function and configuration can be immediately realized. Therefore, the introduction of the system contract registration contract solves the automatic perception that the block chain link point or the application program newly releases and updates the system contract, namely the block chain node or the application program is internally provided with the calling function of the system contract registration contract, so that the function of acquiring the latest address of the system contract and the method thereof can be realized.
Step 103: when the system contract is about to be a new contract, calling the system contract to register the contract as the new contract;

The method creates a system contract registration contract and deploys the system contract registration contract to the blockchain, the system contract registration contract method comprises at least one of registration, updating and query of the system contract, and the written system contract registration contract is deployed to the blockchain network. Wherein the content of the first and second substances,
the method for processing the registration transaction of the system contract registration contract is shown in fig. 3 and comprises the following steps:
step 121: receiving an address of a system contract and a method thereof;
step 122: storing addresses of the system contract and its methods to the blockchain.
The update transaction processing method of the system contract registration contract is shown in fig. 4 and comprises the following steps:
step 131: receiving an original system contract address and an address of a new system contract and a method thereof;
step 132: and replacing the original system contract and the method address thereof with the address of the new system contract and the method thereof, and storing the new system contract and the method thereof in the block chain.
The query transaction processing method of the system contract registration contract is shown in fig. 5 and comprises the following steps:
step 141: inquiring and feeding back all the system contract addresses which are registered in the block chain and can be called;
step 142: and inquiring and feeding back the 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 issuing a system contract and deploying the system contract to the block chain, acquiring the address of the system contract and the address of the method thereof in the block chain.
Because the content of the existing blockchain network has the characteristic of being unchangeable, generally, the upgrading of the blockchain intelligent contract needs to issue a new contract, so that an application system cannot know the address of the new system contract, and the new system contract cannot be directly used. The system contract registration contract has the function that after the system contract and the method thereof are deployed in the blockchain network and are endowed with corresponding storage addresses, the system contract registration contract is used as a public intelligent contract and issues the address of the latest system contract and the method thereof to the whole blockchain network so as to be used by the blockchain link points or application programs needing to call the system contracts.
It should be understood that, since the system contract undertakes some common behaviors in the blockchain network, such as the authority management of the account, the identity management of the account, and the like, when the blockchain contract is used for blockchain system management, the blockchain node or the application program can complete hot update without restarting, that is, update codes are dynamically issued, and the system configuration can be synchronized without restarting a device or the application program. And after a new node or application program is added, the block chain ledger data synchronization is completed, and the same system contract function and configuration can be immediately realized. Therefore, the introduction of the system contract registration contract solves the automatic perception that the block chain link point or the application program newly releases and updates the system contract, namely the block chain node or the application program is internally provided with the calling function of the system contract registration contract, so that the function of acquiring the latest address of the system contract and the method thereof can be realized.
Step 112: when the system contract is about to be a new contract, calling the system contract to register the contract as the new contract;
step 113: when the system contracts an existing contract, calling the system contract to register the contract and updating the existing contract to a new contract.
