Example 1
FIG. 1 is a flowchart of a block-based contract processing method according to an embodiment of the invention; fig. 2 is a block header structure diagram according to an embodiment of the present invention. The embodiment of the invention aims at the problems that in the prior art, the read-write performance of a block chain node is seriously influenced and the data processing efficiency of block chain link points is influenced due to the fact that the transaction quantity is huge and the block quantity in a block chain is large, and the information of each block is read by traversing all blocks.
The method of the present embodiment is applied to nodes, typically consensus nodes, in the block link points for performing block packing operations. In other embodiments, the method may also be applied to other devices, and this embodiment is schematically illustrated using a consensus node as an example.
As shown in fig. 1, the method specifically comprises the following steps:
step S101, when performing the block packing operation, a consensus contract is obtained.
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 to be executed. For example, the consensus contract may perform the function of calculating the total number of all transactions that are blocked to the current block; when the current block is generated, the total number of all the transactions reaching the current block can be obtained by summing the total number of the transactions recorded in the last block and the transaction number of the current block, and the current block is not required to be traversed, so that the method is simple and quick.
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, when performing the block packing operation, obtains one or more consensus contracts that have been consensus-agreed. If there are multiple consensus contracts, the following steps S102-S104 are performed for each consensus contract, and 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 process 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 determines whether the current block satisfies the execution condition of the consensus contract.
For each consensus contract, if the current block meets the execution condition of the consensus contract, steps S103-S104 are executed. If the current block does not meet the execution condition of the consensus contract, the consensus contract is not required to be executed.
Step S103, if the current block meets the execution condition of the consensus contract, executing the consensus contract.
Step S104, adding 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 the unique identification of the consensus contract, and can also be used for uniquely identifying the 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 present embodiment is not particularly limited herein. For example, the contract identification information may include contract name and/or contract version information.
In addition, the execution results of different consensus contracts may have different structures, and the structure of the corresponding execution result may be determined by 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 requirement 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 zero, one, or multiple execution results of the consensus contract.
For example, as shown in fig. 2, the structure of the adjusted block header may include the original attribute information of the block header and the 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 composed of execution results of a plurality of consensus contracts. The contract execution result information includes contract identification information, which is a combination of a contract name and a contract version number, and an execution result.
In fig. 2, the contract execution result information is schematically described by taking the example before other attribute information of the block header, and the position of the contract execution result information is not particularly limited.
According to the embodiment of the invention, the block structure is adjusted, contract execution result information is added in the block header, when the block packing operation is executed, the consensus contract is acquired, whether the current block meets the execution condition of the consensus contract is judged, if the current block meets the execution condition of the consensus contract, the consensus contract is executed, the execution result of the consensus contract is added into the block header of the current block, and the consensus contract based on the block level is realized, so that the corresponding data processing based on the block level 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 only by 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 invention. On the basis of the first embodiment, in this embodiment, when performing the block packing operation, obtaining the consensus contract includes: when a block packing operation is performed, the loaded consensus contract is obtained. Accordingly, before the obtaining of the consensus contract when performing the block packing operation, the method further comprises: analyzing the new consensus contract which is subjected to consensus, and judging whether the new consensus contract has grammar errors or not; if the new consensus contract has no grammar error, loading the new consensus contract.
As shown in fig. 3, the method specifically comprises the following steps:
step S201, analyzing the new consensus contract which is subjected to consensus, and judging whether the new consensus contract has grammar errors or not.
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 to be executed. For example, the consensus contract may perform the function of calculating the total number of all transactions that are blocked to the current block; when the current block is generated, the total number of all the transactions reaching the current block can be obtained by summing the total number of the transactions recorded in the last block and the transaction number of the current block, and the current block is not required to be traversed, so that the method is simple and quick.
In this embodiment, the consensus node may perform the function of block-based contract processing through the following four program modules: an adapter module, a parser module, a loader module, and an executor module.
The adapter module is used for exposing the variable or interface of the blockchain to provide the corresponding variable or interface for the developer to use. For example: at least the following variables or interfaces may be provided: the $ { blockHeight } is the current block height, $ { blockHash } is the current block Hash value (block Hash), $ { txCount } is the number of transactions in the current block, etc.
The common contract is essentially program code for realizing corresponding functions, and the parser module is used for carrying out code parsing and compiling on the common contract provided by the developer, so as to ensure that the common contract has no grammar errors.
Specifically, the new consensus contract after consensus is analyzed and processed to determine whether the new consensus contract has grammar errors. If the new consensus contract has grammar errors, the consensus contract is not loaded.
Alternatively, the new consensus contract may be obtained before parsing the new consensus contract that has undergone consensus; and carrying out consensus processing on the new consensus contracts according to a consensus algorithm to obtain consensus contracts after consensus.
In particular, the new consensus contract may be a consensus contract submitted by an open person. The consensus is performed by all consensus nodes when performing the block packing operation after the consensus has been reached by the 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 the consensus processing on the new consensus contract according to the consensus algorithm is consistent with the existing consensus processing, and this embodiment is not described herein.
In addition, consensus contracts are developed by developers themselves, the patent is not limited to development languages, but the contracts themselves include, but are not limited to, the following: contract identification information, contract execution conditions, and contract execution programs. The contract execution program may call a variable or interface of the blockchain.
Step S202, if the new consensus contract has no grammar error, loading the new consensus contract.
The loader module is configured to load the parsed consensus contract to the loader module based on the consensus contract being free of errors.
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 of the consensus contracts is taken as a target contract, and the following processing of steps S203 to S206 is 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 process 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 determine whether the current block meets the execution condition of the consensus contract. And if the current block meets the execution condition of the consensus contract, calling a contract execution interface to execute the consensus contract. If the current block is determined not to meet the execution condition of the consensus contract, the consensus contract is not executed.
In step S205, if the current block meets the execution condition of the consensus contract, the consensus contract is executed.
Another main function of the actuator module is: when the current block is determined to meet the execution condition of the consensus contract, the consensus contract is executed, and the execution result is added to the block header of the current block.
Step S206, adding 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 the unique identification of the consensus contract, and can also be used for uniquely identifying the 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 present embodiment is not particularly limited herein. For example, the contract identification information may include contract name and/or contract version information.
In addition, the execution results of different consensus contracts may have different structures, and the structure of the corresponding execution result may be determined by 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 requirement 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 zero, one, or multiple execution results of the consensus contract.
For example, as shown in fig. 2, the structure of the adjusted block header may include the original attribute information of the block header and the 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 composed of execution results of a plurality of consensus contracts. The contract execution result information includes contract identification information, which is a combination of a contract name and a contract version number, and an execution result.
In fig. 2, the contract execution result information is schematically described by taking the example before 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 into the contract execution result information of the block header of the current block, so that the execution result can be written into the specified position of the block header (the position where the contract execution result information is located).
According to the embodiment of the invention, the block structure is adjusted, contract execution result information is added in the block header, when the block packing operation is executed, a consensus contract is obtained, whether the current block meets the execution condition of the consensus contract is judged, if the current block meets the execution condition of the consensus contract, the consensus contract is executed, the execution result of the consensus contract is added into the block header of the current block, and the block-level-based consensus contract is realized, so that the corresponding 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 only by querying the data in the latest block, all blocks do not need to be traversed, and the performance and the efficiency of a block chain node are not influenced; and the consensus contract can realize smooth upgrading, and different data processing based on block level can be realized by upgrading the consensus contract without repeatedly adjusting the block structure.
