In the description of the following examples, "plurality" means two or more unless specifically limited otherwise.
The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Example one
FIG. 1 is a flowchart of a block-based contract processing method according to an embodiment of the present invention; fig. 2 is a schematic block head structure according to an embodiment of the invention. The embodiment of the invention provides a block-based contract processing method aiming at the problems that in the prior art, when the transaction quantity is very large and the quantity of blocks in a block chain is large, the information of each block is read by traversing all the blocks, the reading and writing performance of the nodes of the block chain is seriously influenced, and the processing efficiency of the data of the nodes of the block chain is influenced.
The method in this embodiment is applied to a node, typically a common node, in a block link node for performing a block packing operation. In other embodiments, the method may also be applied to other devices, and the embodiment takes the consensus node as an example for schematic illustration.
As shown in fig. 1, the method comprises the following specific steps:
step S101, acquiring a consensus contract when the block packing operation is executed.
Wherein, the consensus contract refers to an intelligent contract passing through a consensus block layer.
In this embodiment, a developer may develop and generate a consensus contract by processing data of a block level that needs to be executed. For example, the consensus contract may perform the function of calculating the total number of all transactions that have been up to the current block; when the current block is generated, the total transaction amount of all transactions ending at the current block can be obtained only by summing the transaction total amount recorded in the previous block and the transaction amount of the current block, and the process is simple and quick without traversing all blocks.
When the consensus contract is executed by the consensus node, the function of data processing of the block level corresponding to the consensus contract can be realized, and the execution result is the processing result of the data processing of the corresponding block level.
The consensus node acquires one or more consensus contracts which are already known when the block packaging operation is executed. If there are multiple consensus contracts, the following steps S102-S104 are performed for each consensus contract, respectively, each consensus contract is executed to obtain an execution result, and the execution result is added to the block header of the current block.
In addition, if the block hash value in the block structure is a hash value of the entire block, it is necessary to complete the processing of executing the consensus contract and adding the execution result to the block header of the current block before calculating the block hash value.
Step S102, judging whether the current block meets the execution condition of the consensus contract.
Before each consensus contract is executed, the consensus node first judges whether the current block meets the execution condition of the consensus contract.
For each consensus contract, if the current block meets the execution condition of the consensus contract, the steps S103-S104 are performed. If the current block does not meet the execution condition of the consensus contract, the consensus contract does not need to be executed.
Step S103, if the current block meets the execution condition of the consensus contract, executing the consensus contract.
And step S104, adding the execution result of the consensus contract into the block header of the current block.
In this embodiment, the block structure is adjusted, and contract execution result information is added to the block header. The contract execution result information includes at least: contract identification information and execution results.
The contract identification information is used for uniquely identifying a consensus contract, has uniqueness, can be used as a unique identifier of the consensus contract, and can also be used for uniquely identifying an execution result of the consensus contract. The contract identification information may be any information that can be used to uniquely identify a consensus contract, and the embodiment is not specifically limited herein. For example, the contract identification information may include a contract name and/or contract version information.
In addition, the execution results of different consensus contracts can have different structures, and the structures corresponding to the execution results can be determined through contract identification information. The execution result of the consensus contract may be a result set, and the specific structure of the execution result may be set by a technician according to the function and the need of the consensus contract, which is not specifically limited herein.
Further, the contract execution result information in the block header of the block structure may include the execution results of zero, one, or more consensus contracts.
For example, the structure of the adjusted block header is as shown in fig. 2, and the block header may include original attribute information of the block header and contract execution result information of the consensus contract. The block header shown in fig. 2 includes contract execution result information corresponding to 3 consensus contracts, and the block header includes a formula contract result set formed by execution results of a plurality of consensus contracts. The contract execution result information includes contract identification information combined by the contract name and the contract version number, and an execution result.
In fig. 2, the contract execution result information is schematically illustrated as being preceded by other attribute information of the block header, and the position of the contract execution result information is not particularly limited.
The embodiment of the invention adjusts the block structure, adds the contract execution result information in the block head, acquires the consensus contract when performing the block packing operation, judges whether the current block meets the execution condition of the consensus contract, executes the consensus contract if the current block meets the execution condition of the consensus contract, and adds the execution result of the consensus contract into the block head of the current block to realize the block-level-based consensus contract, so that the block-level-based data processing can be completed through the execution of the consensus contract in the process of packing and generating the block, the query result can be obtained by subsequently querying the data in the latest block, all blocks do not need to be traversed, and the performance and the efficiency of the block chain node are not influenced.
Example two
Fig. 3 is a flowchart of a block-based contract processing method according to a second embodiment of the present invention. On the basis of the first embodiment, in this embodiment, when performing the block packing operation, acquiring the consensus contract includes: when the block packing operation is executed, the loaded consensus contract is obtained. Correspondingly, when the block packing operation is executed, before the obtaining of the consensus contract, the method further comprises the following steps: analyzing the new consensus contract after consensus and judging whether the new consensus contract has grammar errors or not; and if the new consensus contract has no grammar error, loading the new consensus contract.
As shown in fig. 3, the method comprises the following specific steps:
step S201, parsing the new consensus contract after consensus, and determining whether the new consensus contract has a syntax error.
Wherein, the consensus contract refers to an intelligent contract passing through a consensus block layer.
In this embodiment, a developer may develop and generate a consensus contract by processing data of a block level that needs to be executed. For example, the consensus contract may perform the function of calculating the total number of all transactions that have been up to the current block; when the current block is generated, the total transaction amount of all transactions ending at the current block can be obtained only by summing the transaction total amount recorded in the previous block and the transaction amount of the current block, and the process is simple and quick without traversing all blocks.
In this embodiment, the consensus node may complete the function of block-based contract processing through the following four program modules: the system comprises an adapter module, a resolver module, a loader module and an actuator module.
The adapter module is used for exposing the variable or interface of the blockchain, so that the corresponding variable or interface can be provided for developers to use. For example: at least the following variables or interfaces may be provided: $ blockHeight $ current chunk height, $ { blockHash } current chunk Hash value (chunk Hash), $ { txCount } current chunk transaction number, etc.
The common agreement is essentially a program code for realizing corresponding functions, and the analyzer module is used for analyzing and compiling the code of the common agreement provided by a developer to ensure that the common agreement has no syntax errors.
Specifically, the new consensus contract that is identified is analyzed to determine whether the new consensus contract has a syntax error. If the new consensus contract has a grammatical error, the consensus contract will not be loaded.
Optionally, before parsing the new consensus contract that is identified, a new consensus contract may be obtained; and carrying out consensus processing on the new consensus contract according to a consensus algorithm to obtain a consensus contract.
In particular, the new consensus contract may be a consensus contract submitted by an open staff. The consensus is performed by all consensus nodes while performing the block packing operation after the consensus is achieved by all consensus nodes.
The consensus algorithm may be set by a technician according to actual needs, and the embodiment is not specifically limited herein. The process of performing consensus processing on the new consensus contract according to the consensus algorithm is consistent with the existing consensus processing, and is not described herein again in this embodiment.
In addition, the consensus contract is developed by developers, the patent does not limit the development language, but the contract itself includes but is not limited to the following parts: contract identification information, contract execution conditions, and contract execution programs. The contract execution program may call a variable or interface of the blockchain.
And step S202, if the new consensus contract has no grammar error, loading the new consensus contract.
And on the basis that the consensus contract has no error, the loader module is used for loading the parsed consensus contract to the loader module.
Step S203, when the block packing operation is performed, the loaded consensus contract is obtained.
When the consensus contract is executed by the consensus node, the function of data processing of the block level corresponding to the consensus contract can be realized, and the execution result is the processing result of the data processing of the corresponding block level.
The consensus node obtains the loaded one or more consensus contracts from the loader module when performing the block packing operation.
If a plurality of consensus contracts are acquired, each consensus contract is respectively used as a target contract, and the following steps S203-S206 are performed on the target contract, so that all the loaded consensus contracts are traversed.
In addition, if the block hash value in the block structure is a hash value of the entire block, it is necessary to complete the processing of executing the consensus contract and adding the execution result to the block header of the current block before calculating the block hash value.
Step S204, judging whether the current block meets the execution condition of the consensus contract.
One of the main functions of the actuator module is: and judging whether the current block meets the execution condition of the consensus contract.
Before each consensus contract is executed, a contract execution condition interface is called first to judge whether the current block meets the execution condition of the consensus contract. And if the current block is determined to meet the execution condition of the consensus contract, calling a contract execution interface to execute the consensus contract. And if the current block is determined not to meet the execution condition of the consensus contract, not executing the consensus contract.
Step S205, if the current block meets the execution condition of the consensus contract, executing the consensus contract.
Another major function of the actuator module is: and when the current block is determined to meet the execution condition of the consensus contract, executing the consensus contract, and adding the execution result to the block header of the current block.
Step S206, add the execution result of the consensus contract to the block header of the current block.
In this embodiment, the block structure is adjusted, and contract execution result information is added to the block header. The contract execution result information includes at least: contract identification information and execution results.
The contract identification information is used for uniquely identifying a consensus contract, has uniqueness, can be used as a unique identifier of the consensus contract, and can also be used for uniquely identifying an execution result of the consensus contract. The contract identification information may be any information that can be used to uniquely identify a consensus contract, and the embodiment is not specifically limited herein. For example, the contract identification information may include a contract name and/or contract version information.
In addition, the execution results of different consensus contracts can have different structures, and the structures corresponding to the execution results can be determined through contract identification information. The execution result of the consensus contract may be a result set, and the specific structure of the execution result may be set by a technician according to the function and the need of the consensus contract, which is not specifically limited herein.
Further, the contract execution result information in the block header of the block structure may include the execution results of zero, one, or more consensus contracts.
For example, the structure of the adjusted block header is as shown in fig. 2, and the block header may include original attribute information of the block header and contract execution result information of the consensus contract. The block header shown in fig. 2 includes contract execution result information corresponding to 3 consensus contracts, and the block header includes a formula contract result set formed by execution results of a plurality of consensus contracts. The contract execution result information includes contract identification information combined by the contract name and the contract version number, and an execution result.
In fig. 2, the contract execution result information is schematically illustrated as being preceded by other attribute information of the block header, and the position of the contract execution result information is not particularly limited.
In this step, the execution result is written in the contract execution result information of the block header of the current block, so that the execution result can be written in a specified position (position where the contract execution result information is located) of the block header.
The embodiment of the invention adjusts the block structure, adds the contract execution result information in the block head, acquires the consensus contract when executing the block packing operation, judges whether the current block meets the execution condition of the consensus contract, if the current block meets the execution condition of the consensus contract, executes the consensus contract, adds the execution result of the consensus contract into the block head of the current block, realizes the consensus contract based on the block hierarchy, thereby completing the corresponding data processing based on the block hierarchy by executing the consensus contract in the process of packing and generating the block, obtaining the query result by subsequently querying the data in the latest block without traversing all the blocks and influencing the performance and efficiency of the block chain node; and the consensus contract can realize smooth upgrading, different data processing based on the block hierarchy can be realized by upgrading the consensus contract, and the repeated adjustment of the block structure is not needed.
