Examples
In order to improve the consensus efficiency, embodiments of the present application provide a block chain-based consensus method, an apparatus, and a storage medium, where the block chain-based consensus method, the apparatus, and the storage medium can complete consensus through one-time verification, so that the consensus is simpler and more convenient, and the block chain consensus efficiency is improved.
First, in order to more intuitively understand the scheme provided by the embodiment of the present application, a system architecture of the block chain-based consensus achieving scheme provided by the embodiment of the present application is described below with reference to fig. 1.
Fig. 1 is a schematic application environment diagram of a block chain-based consensus method, an apparatus and a storage medium according to one or more embodiments of the present application. As shown in fig. 1, a block consensus network is formed by one-to-one communication connection among a plurality of consensus nodes, and each consensus node is in communication connection with one or more candidate nodes for data communication or interaction. Wherein, one of the common nodes in the block common-identification achieving network is a block outlet node needing to outlet blocks.
The block chain-based consensus method provided in the embodiments of the present application will be described in detail below.
As shown in fig. 2, which is a flowchart of a block chain-based consensus method applied to a block output node according to an embodiment of the present application, the block chain-based consensus method may include the following steps:
and S201, executing the transaction in the local transaction pool to generate a confirmation block to be signed.
The local transaction pool is a transaction pool of the designated block node end, and the confirmation block to be signed comprises the transaction and the temporary transaction result.
In the embodiment of the application, mutual exclusion resources do not exist among partial transactions in the local transaction pool, namely, common resources cannot be occupied among the partial transactions. Therefore, when executing the transaction in the local transaction pool, the out-blocking node can sequence the transactions in the local transaction pool first and select the batch transaction without the mutually exclusive resource, and when executing the transaction in the local transaction pool, the batch transaction without the mutually exclusive resource can be executed in parallel, and the transaction with the mutually exclusive resource is executed in series. Thus, CPU resources of the machine can be utilized to the maximum extent, and the throughput of transaction processing can be improved.
Step S202, the confirmation block to be signed is synchronized to other consensus nodes so that the other consensus nodes can verify the transaction after the transaction is executed.
After executing the transaction in the local transaction pool and generating the confirmation block to be signed, the block-out node may synchronize the confirmation block to be signed to other consensus nodes through the network achieving consensus, where the other consensus nodes are consensus nodes in the network achieving block consensus except the block-out node.
For example, the block consensus network includes a consensus node a, a consensus node B, a consensus node C and a consensus node D, and if the consensus node a is a block node, the other consensus nodes are the consensus node B, the consensus node C and the consensus node D.
After the other common identification nodes receive the confirmation block to be signed, each common identification node in the other common identification nodes executes the transaction in the confirmation block to be signed and generates a temporary transaction result. And each of the consensus nodes compares the generated transaction temporary result with the transaction temporary result in the confirmation block to be signed, judges whether the transaction temporary result is consistent with the transaction temporary result in the confirmation block to be signed, if so, indicates that the verification is passed, and if not, indicates that the verification is not passed.
In this embodiment, after receiving the confirmation block to be signed, the other consensus nodes may also buffer the temporary transaction result in the confirmation block to be signed into their respective state buffer pools, where a state buffer pool is a state set established on the consensus node for temporarily storing a state.
And S203, receiving a verification signature returned by the common identification node passing the verification.
And the common identification node which passes the verification generates a verification signature and returns the verification signature to the given block node, and the given block node receives the verification signature returned by the common identification node which passes the verification.
And S204, if the occupation ratio of the common identification nodes returning the verification signature in all the common identification nodes exceeds a preset ratio, writing the signature information into the block to be confirmed and broadcasting the signature information to other common identification nodes.
The block-out node can preset a ratio for judging whether to achieve consensus, after receiving the verification signature returned by the consensus node passing the verification, the block-out node can judge whether the occupation ratio of the consensus node of the returned verification signature in all the consensus nodes exceeds the preset ratio, if the occupation ratio of the consensus node of the returned verification signature in all the consensus nodes exceeds the preset ratio, the consensus is achieved, and at the moment, the signature information is written into the block to be confirmed and broadcasted to other consensus nodes, so that the other consensus nodes take out the temporary result of the cached transaction from the respective state cache pools to update the block chain.
The preset ratio can be adjusted, for example, the preset ratio can be 1/2, 2/3, 3/4, etc., and is not particularly limited in the embodiments of the present application.
Thus, by executing the transaction in the local transaction pool, the block to be signed is generated as a confirmation block, and then the confirmation block to be signed is synchronized to other consensus nodes, so that the other consensus nodes verify the transaction after executing the transaction, and when the occupation ratio of the returned consensus nodes for verifying the signature in all the consensus nodes exceeds a preset ratio, the signature information is written into the block to be confirmed and broadcast to the other consensus nodes, so that the other consensus nodes take out the temporary result of the cached transaction from their respective state cache pools to perform block chain update. Therefore, consensus can be achieved through one-time verification, the consensus achieving process is simpler and more convenient, and the consensus achieving efficiency of the block chain is improved. Meanwhile, the transactions in the local transaction pool can be sequenced firstly, batch transactions without mutually exclusive resources are selected, when the transactions in the local transaction pool are executed, the batch transactions without the mutually exclusive resources are executed in parallel, and the transactions with the mutually exclusive resources are executed in series, so that the CPU resources of the machine are utilized to the maximum extent, and the throughput of transaction processing is improved.
In a second aspect, an embodiment of the present application provides another block chain based consensus method, which can be applied to a block chain based consensus network, please refer to fig. 3, where the block chain based consensus method includes:
and S301, the block output node executes the transaction in the local transaction pool to generate a to-be-signed confirmation block.
Wherein, the confirmation block to be signed comprises the transaction and the temporary result of the transaction.
In the embodiment of the present application, before the block-out node executes the transaction in the local transaction pool, the block-out node may be determined from the block consensus network by using a random extraction algorithm.
Step S302, the block output node synchronizes the confirmation block to be signed to other common nodes.
And S303, verifying the transaction after the other consensus nodes execute the transaction, and storing the temporary transaction result into respective state cache pools.
Specifically, each of the other consensus nodes compares the temporary transaction result generated by the consensus node executing the transaction with the temporary transaction result generated by the block-out node executing the transaction. If the two are consistent, the verification is passed, and if the two are not consistent, the verification is not passed.
In the embodiment of the application, after receiving the confirmation area to be signed, the other consensus nodes store the temporary transaction result in the confirmation area to be signed into the respective state cache pools.
And S304, returning respective verification signatures to the common identification nodes passing the verification to give the block nodes.
Step S305, if the occupation ratio of the common identification nodes returning the verification signatures exceeds the preset ratio in all the common identification nodes, the block outlet node writes the signature information into the block to be confirmed and broadcasts the signature information to other common identification nodes so that other common identification nodes can take out the cached temporary transaction results from the respective state cache pools to update the block chain.
