Detailed Description
In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and the specific embodiments of the specification, and it should be understood that the specific features in the embodiments and examples of the present application are detailed descriptions of the technical solutions of the present application, but not limitations of the technical solutions of the present application, and the technical features in the embodiments and examples of the present application may be combined with each other without conflict.
The terms appearing in the embodiments of the present application are explained first below.
Block chains: as shown in fig. 1, a block chain is a chain consisting of a series of blocks, and each block records a Hash value of the block in addition to the data of the block, so that a chain is formed. The block chain has two core ideas, one is a cryptography technology, the other is a decentralization idea, and based on the two ideas, historical information on the block chain cannot be tampered.
And (3) node: each participant in the network is a node that participates in network set-up and data exchange. In a blockchain network, a node refers to a participant with a unique identity, and the node has a complete copy of the ledger and has the capability of participating in the consensus and ledger maintenance of the blockchain network.
Intelligent contract: an intelligent contract is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible. The specific form of the intelligent contract is a code which is deployed on a block chain and completes a specific function. For example, identity is a mainstream intelligent contract programming language, and an intelligent contract written in the identity language is called an identity contract. When an intelligent contract is deployed on a blockchain, a contract address is generated, and a user can call the intelligent contract through the contract address. The function defined in the intelligent contract is called a contract interface, and the calling of the intelligent contract is to call a certain contract interface in the contract through a contract address.
Trading: a transaction is a user request for an operation of an intelligent contract interface deployed on a blockchain. The transaction is initiated by the user, sent from the client of the user to the block chain node, and after receiving the transaction, the block chain node calls the corresponding intelligent contract according to the contract address and the interface specified by the transaction.
A consensus mechanism: the consensus mechanism is that transaction nodes on the peer-to-peer network use a common algorithm to confirm a batch of transactions. The algorithms used include workload certification, equity certification, multiple signature verification, election verification, etc.
During the operation of a financial institution (a banking institution, an insurance institution or a security institution) in a business (such as a loan business, a deposit business and the like of a bank), the processing performance of a block chain of the financial institution is often analyzed. Current approaches use one transaction to perform an analysis of processing performance for a single blockchain. However, in a cross-blockchain scenario, due to the confirmation and the whole processing flow of the cross-chain transaction, multiple blockchain systems need to participate together, and multiple related transactions on the multiple blockchain systems are involved, which is measured by the processing capacity of a single transaction, and it is difficult to reflect the real performance of the cross-chain scenario. The situation is not in line with the requirements of financial institutions such as banks and the like, and is not beneficial to the efficient operation of various businesses of the financial institutions.
To this end, as shown in fig. 2, the present application provides a processing performance analysis method for a blockchain network.
Step 201: multiple cross-chain transactions are performed in a blockchain network.
The cross-chain transaction is a transaction completed by sequentially executing a plurality of transactions on a plurality of blockchains of the blockchain network; the multiple transactions corresponding to each cross-chain transaction have the same transaction identification.
Step 202: and determining the processing performance of the blockchain network according to the initiation time and the uplink time of each transaction in the cross-chain transaction.
It should be noted that the method of step 201 to step 202 is suitable for a cross-chain scenario. For example, the cross-chain scenario is divided according to architecture and interaction mode, and the cross-chain scenario is divided into three scenarios, namely multi-chain isomorphic direct interaction, heterogeneous direct interaction and heterogeneous indirect interaction:
as shown in fig. 3, in the isomorphic chain direct interaction mode, the blockchain a and the blockchain B belong to different services, and have the same underlying architecture and two blockchains with different network architectures, storage and consensus mechanisms, the two blockchains are directly connected through a network agent, a Software Development Kit (SDK) or other Software, and cross-chain interaction occurs between the two blockchains. The service of the block chain refers to the use of the block chain, and the bottom layer architecture of the block chain refers to the specific product of the block chain, for example, the block chain is a bitcoin, and the block chain is an ether house.
As shown in fig. 4, in the heterogeneous chain direct interaction mode, the blockchain a and the blockchain B belong to different services, and have two blockchains with different underlying architectures, different network architectures, and storage and consensus mechanisms, where the two blockchains cannot directly communicate with each other, and perform transaction and conversion of blockdata through the protocol switching module to establish connection, and the protocol switching module is only used as a channel and is responsible for conversion of data formats, and has no independent chain or consensus mechanism
As shown in fig. 5, in the heterogeneous chain indirect interaction mode, the blockchain a and the blockchain B belong to different services, and have two blockchains with different underlying architectures, different network architectures, and storage and consensus mechanisms, where the two blockchains cannot directly communicate and are connected to the relay chain through the protocol transfer module, and the relay chain stores the cross-chain states of the blockchain a and the blockchain B, coordinates the cross-chain process, and has an independent chain and consensus mechanism
In step 201, for different cross-chain scenarios, cross-chain transactions may be executed through a unified flow, so as to perform a processing performance test on a blockchain network, where a core of the processing performance test is to correctly determine an initiation time and an end time of a single cross-chain transaction, each cross-chain transaction has a unique transaction Identifier (ID), and all transactions generated by the cross-chain transactions store the transaction ID, and the flow is as follows:
the first step is to start a cross-chain transaction and initiate a cross-chain starting transaction to any blockchain participating in the cross-chain transaction. The transaction is initiated, i.e., the first transaction of the cross-chain transaction.
And secondly, confirming successful uplink of the initiated transaction, and recording the transaction ID of the cross-chain transaction, the initiation time and uplink time of the transaction.
And thirdly, in the cross-chain transaction process, a plurality of transactions related to the cross-chain transaction are generated in succession by the participating block chain, protocol switching module or relay chain, the transactions are tracked and recorded by using the transaction ID, and the initiation time and uplink time of the transactions are recorded.
And fourthly, confirming that the last step of transaction in the cross-chain transaction is successful in uplink, and recording the initiation time and uplink time of the transaction.
After a process of the cross-chain transaction is completed, a blockchain, a sending time and an uplink time of all transactions of the whole cross-chain transaction can be obtained, and all transaction information processed by the cross-chain transaction can be recorded no matter which cross-chain scene is used.
As shown in table 1, taking a heterogeneous indirect interaction scenario as an example, the execution flow of the cross-chain goods transaction is as follows:
TABLE 1
The unit of the time in table 1 may be set according to a specific scenario, such as the unit is milliseconds (ms), and step 202 is described in detail below in conjunction with the cross-link item transaction flow shown in table 1.
In an optional implementation manner of step 202, when the processing performance of the blockchain network is an average processing duration of the blockchain network processing the cross-chain transaction, step 202 may be specifically executed in the following manner:
regarding each cross-chain transaction in the plurality of cross-chain transactions, taking an interval duration between an uplink time of a last transaction and an initiation time of a first transaction of the cross-chain transactions as a processing duration of the cross-chain transactions; and determining the average processing duration of the block chain network according to the processing durations of the plurality of cross-chain transactions, the weight values of the plurality of cross-chain transactions and the transaction number of the plurality of cross-chain transactions.
As in the example shown in table 1, the difference 0600 between the uplink time 0700 of the last transaction with the serial number 6 and the initiation time 0100 of the first transaction with the serial number 1 is used as the processing duration of the cross-chain goods transaction. The processing duration of each cross-chain transaction may be calculated according to this alternative embodiment. The processing duration of each cross-chain transaction may be preset with a weight value, for example, the number of transactions executing 3 cross-chain transactions is 3. Then the average processing time for the blockchain network can be determined as follows: t ═ (w1 × t1+ w2 × t2+ w3 × t 3)/3. Specifically, w1 ═ w2 ═ w3 ═ 1.
In an optional implementation manner of step 202, when the processing performance of the blockchain network is the transaction confirmation performance of each blockchain in the blockchain network, step 202 may be specifically executed in the following manner:
(1) and aiming at each block chain of the block chain network, determining the transaction confirmation duration of each transaction in the block chain according to the initiation time and the uplink time of each transaction initiated on the block chain by the plurality of cross-chain transactions.
For the example shown in table 1, the difference between the uplink time 0200 of the transaction with sequence number 1 of the cross-chain item transaction with the transaction duration of sequence number 1 and the initiation time 0100 of the transaction with sequence number 1 is 0100, that is, the transaction confirmation duration of the transaction with sequence number 1 is 0100.
(2) And determining whether a performance bottleneck exists in the transaction confirmation performance of the blockchain at least according to the transaction confirmation duration of each transaction initiated on the blockchain.
Step (2) may be performed in the following manner:
and determining the fluctuation degree of the transaction confirmation duration of the blockchain according to the transaction confirmation duration of each transaction initiated on the blockchain.
For example, the fluctuation degree of the transaction confirmation duration of the blockchain is characterized by the variance of the transaction confirmation duration of each transaction of the blockchain. The fluctuation degree of the transaction confirmation duration of the blockchain can be represented by the standard deviation, the normalized variance and the like of the transaction confirmation duration of each transaction of the blockchain, and is not limited herein.
If the fluctuation degree of the transaction confirmation duration of the blockchain is determined to be higher, determining that a performance bottleneck exists in the transaction execution performance in the transaction confirmation performance of the blockchain; or if the fluctuation degree of the transaction confirmation duration of the blockchain is determined to be low, and the average transaction confirmation duration of the blockchain is not greater than the preset duration, determining that the transaction execution performance in the transaction confirmation performance of the blockchain has no performance bottleneck.
It should be noted that the determination method that the transaction confirmation duration of the blockchain fluctuates to a higher or lower degree may be set according to specific situations. And determining the fluctuation degree of the transaction confirmation duration of the blockchain according to the variance of the transaction confirmation duration of the blockchain and a preset variance threshold. When the variance of the transaction confirmation duration is larger than a preset variance threshold, determining that the fluctuation degree of the transaction confirmation duration of the block chain is higher; and when the variance of the transaction confirmation duration is not greater than the preset variance threshold, determining that the fluctuation degree of the transaction confirmation duration of the block chain is lower. When the fluctuation degree of the transaction confirmation duration of the blockchain is large, whether the logic of a specific transaction on the blockchain is too complex or not can be confirmed, a bottleneck is likely to exist, and whether the original logic can be split into a plurality of transactions or whether part of the logic is distributed to other blockchains or not is evaluated.
Further, the transaction confirmation duration of each transaction initiated on the blockchain comprises the transaction execution duration of the transaction and the blockconsensus duration of the transaction; (2) may further perform the following steps:
and if the fluctuation degree of the transaction confirmation duration of the blockchain is determined to be low, and the average transaction confirmation duration of the blockchain is greater than the preset duration, determining that the transaction confirmation performance of the blockchain has a bottleneck, and determining a first proportion and a second proportion. If the first proportion is larger than the second proportion, determining that a performance bottleneck exists in the transaction execution performance in the transaction confirmation performance of the block chain; or, if the first ratio is not greater than the second ratio, determining that a performance bottleneck exists in the block consensus performance in the transaction confirmation performance of the block chain.
It should be noted that the first proportion is a ratio of the total transaction execution duration of the blockchain to the total transaction confirmation duration of the blockchain; the second proportion is the proportion of the total block consensus duration of the block chain in the total transaction confirmation duration of the block chain. The total transaction execution time length of the blockchain is the sum of the transaction execution time lengths of each transaction of the blockchain. The total transaction confirmation duration of the blockchain is the sum of the transaction confirmation durations of each transaction of the blockchain. The total block consensus duration of the block chain is the sum of the block consensus durations of each transaction of the block chain.
If the fluctuation degree of the transaction confirmation duration of a certain block chain is small, and the average transaction confirmation duration of the block chain is maintained at a large value (if the fluctuation degree is larger than the preset duration), block chain log confirmation is required, and the first proportion and the second proportion are used, and if the second proportion is large, namely the block consensus duration is large, the block chain consensus process is abnormal, and the problems that consensus nodes are too many, consensus algorithms are too complex or the consensus nodes are abnormal are likely to exist. If the first ratio is larger, that is, the transaction execution duration is larger, indicating that there is an abnormality in the transaction execution process of the blockchain, it may be determined whether the logic of a specific transaction on the blockchain is too complex, and there is a possibility of a bottleneck, and it is evaluated whether the original logic can be split into multiple transactions or part of the logic can be allocated to other blockchains. .
In an optional implementation manner after step 201, for any block chain of the block chain network, determining a block packing saturation level of the block chain according to a cross-chain transaction number, in which a block transaction number of the block chain is not less than an upper limit of the block transaction number of the block chain, in an execution process of the multiple cross-chain transactions. When the block transaction quantity is equal to the upper limit of the block transaction quantity of the block chain, the blocks of the block chain are packaged
For example, a total of 10 cross-chain transactions are performed. And 8 cross-chain transactions of which the block transaction number of the block chain is not less than the block transaction number upper limit of the block chain are provided, namely the block chain has block packing for 8 times in the process of executing 10 cross-chain transactions. Particularly, if the block chain always reaches the upper limit of the block transaction number of the block chain in the process of executing 10 cross-chain transactions, it indicates that the block chain bears excessive pressure in the executing process, and the block chain cannot process all received transactions in time, so that the block packaging is always in a saturated state; for another example, during the execution of 10 inter-chain transactions, the blockchain is always lower than the upper limit of the number of blockchain transactions, which indicates that the pressure of the blockchain is insufficient and a sufficient amount of pressure is not received, so that the sizes of blocks of multiple chains in the inter-chain transactions can be coordinated to balance the load, and the overall performance of the inter-chain transactions can be improved.
As shown in fig. 6, the present application provides a processing performance analysis apparatus for a blockchain network, including: an execution module 601, configured to execute a plurality of cross-chain transactions in a blockchain network; wherein each of the plurality of inter-chain transactions is a transaction completed by sequentially executing a plurality of transactions on a plurality of blockchains of the blockchain network; the multiple transactions corresponding to each cross-chain transaction have the same transaction identification; a determining module 602, configured to determine a processing performance of the blockchain network according to an initiation time and an uplink time of each transaction in the multiple cross-chain transactions.
