Detailed Description
In order to better understand the above technical solutions, the following detailed description will be made with reference to the accompanying drawings and specific embodiments, and it should be understood that specific features in the embodiments and examples of the present application are detailed descriptions of the technical solutions of the present application, and not limit 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.
Blockchain: as shown in fig. 1, a blockchain is a chain of blocks, each block being recorded with a Hash value of the previous block in addition to the data of the block, in such a way that the chain is formed. The block chain has two core concepts, one is a cryptography technology, the other is a decentralization concept, and the history information on the block chain cannot be tampered based on the two concepts.
And (3) node: each participant in the network is a node that participates in network construction and data exchange. In a blockchain network, a node refers to a participant with a unique identity, the node having a complete ledger copy with the ability to participate in blockchain network consensus and ledger maintenance.
Intelligent contract: an intelligent contract is a computer protocol that aims to propagate, verify, or execute contracts in an informative manner. Smart contracts allow trusted transactions to be made without third parties, which transactions are traceable and irreversible. The smart contracts are in the form of code deployed on a blockchain to perform a specific function. For example, solubility is a mainstream smart contract programming language, and smart contracts written in the solubility language are called solubility contracts. When an intelligent contract is deployed onto a blockchain, a contract address is generated through which a user may invoke the intelligent contract. A function defined in an intelligent contract, called a contract interface, calls to an intelligent contract, are calls to a certain contract interface in the contract through a contract address.
Transaction: a transaction is a request by a user for an operation of an intelligent contract interface deployed on a blockchain. The transaction is initiated by a user, the transaction is sent to a blockchain node from a client of the user, and after the blockchain node receives the transaction, the corresponding intelligent contract is called according to a contract address and an interface appointed by the transaction.
Consensus mechanism: the consensus mechanism refers to each transaction node on the peer-to-peer network, and uses a common algorithm to confirm a batch of transactions. The algorithm comprises workload certification, rights and interests certification, multiple signature verification, election verification and the like.
In the running process of a financial institution (banking institution, insurance institution or securities institution) in doing business (such as loan business, deposit business, etc. of a bank), the processing performance of a blockchain of the financial institution is often analyzed. Current approaches use one transaction to analyze processing performance for a single blockchain. However, in the case of cross-blockchain, because of the confirmation and the full process of cross-chain transaction, multiple blockchain systems are required to participate in common, and multiple related transactions on multiple blockchain systems are involved, which is measured by the processing capability of a single transaction, and the real performance of the cross-chain scene is difficult to reflect. This situation does not meet the requirements of financial institutions such as banks, and is also disadvantageous to 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 of a blockchain network.
Step 201: a plurality of cross-chain transactions are performed at the 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; each cross-chain transaction corresponds to a plurality of transactions with the same transaction identification.
Step 202: and determining the processing performance of the blockchain network according to the starting time and the uplink time of each transaction in the cross-chain transaction.
It should be noted that the method from step 201 to step 202 is applicable to a cross-link scenario. For example, the cross-link scenarios are divided according to architecture and interaction, and the cross-link scenarios are divided into three scenarios of multi-link isomorphic direct interaction, heterogeneous direct interaction and heterogeneous indirect interaction:
as shown in fig. 3, in the isomorphic direct interaction mode, the blockchain a and the blockchain B belong to different services, have the same underlying architecture, and are two blockchains with different network architectures, storage and consensus mechanisms, and the two blockchains are directly connected through a network agent program, a software development kit (Software Development Kit, SDK) or other software, so that cross-chain interaction occurs between the two blockchains. The business of the blockchain refers to the use of the blockchain, and the bottom architecture of the blockchain refers to a specific product of the blockchain, such as that the blockchain is a bitcoin and the blockchain is an ethernet.
As shown in FIG. 4, in the heterogeneous chain direct interaction mode, the blockchain A and the blockchain B belong to two blockchains belonging to different services and having different bottom layer structures, different network structures and storage and consensus mechanisms, the two blockchains cannot directly communicate, transaction and block data conversion are performed through a protocol switching module, connection is established, the protocol switching module is only used as a channel and is responsible for data format conversion, and no independent chain and consensus mechanism exists
As shown in FIG. 5, in the heterogeneous chain indirect interaction mode, the blockchain A and the blockchain B belong to two blockchains with different services, different bottom layer structures, different network structures, storage and consensus mechanisms, the two blockchains cannot directly communicate, are connected to a relay chain through a protocol switching module, the relay chain stores the cross-chain state of the blockchain A and the blockchain B, coordinates the cross-chain flow, and has independent chains and consensus mechanisms
In step 201, for different cross-link scenarios, cross-link transactions may be executed through a unified flow, so as to perform a processing performance test on a blockchain network, where the core of the processing performance test is to correctly determine the starting time and the ending time of a single cross-link transaction, each cross-link transaction has a unique transaction Identifier (ID), and all transactions generated by the cross-link transaction store the transaction ID, where the flow is as follows:
first, a cross-chain transaction is initiated, and a cross-chain initiation transaction is initiated to any blockchain participating in the cross-chain transaction. The first transaction of the transaction, the cross-chain transaction, is initiated.
And secondly, confirming that the starting transaction is successfully uplink, and recording the transaction ID of the cross-link transaction, and the starting time and the uplink time of the transaction.
And thirdly, in the cross-link transaction flow, a plurality of transactions related to the cross-link transaction are generated successively by the participated blockchain, protocol transfer module or relay chain, and transaction IDs are used for tracking and recording the transactions, and the initiating time and the uplink time of the transactions are recorded.
And fourthly, confirming that the last transaction in the cross-link transaction is successful in the uplink, and recording the starting time and the uplink time of the transaction.
After the flow of one cross-link transaction is completed, the blockchain, the sending time and the uplink time of all transactions of the whole cross-link transaction can be obtained, and all transaction information of the cross-link transaction can be recorded no matter which cross-link scene.
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 units of time in table 1 may be set according to a specific scenario, for example, units of milliseconds (ms), and step 202 is described in detail below in conjunction with the cross-chain article transaction flow shown in table 1.
In an alternative embodiment 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 specifically be performed in the following manner:
for each of the plurality of cross-chain transactions, taking the interval duration between the uplink time of the last transaction of the cross-chain transaction and the initiation time of the first transaction as the processing duration of the cross-chain transaction; and determining the average processing time length of the blockchain network according to the processing time length of the plurality of cross-chain transactions, the weight values of the plurality of cross-chain transactions and the transaction quantity 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 sequence number 6 and the initiation time 0100 of the first transaction with the sequence number 1 is taken as the processing duration of the cross-chain goods transaction. The processing time length of each cross-chain transaction may be calculated in accordance with this alternative embodiment. The processing duration of each cross-chain transaction may be preset to a weight value, for example, the number of transactions that execute 3 cross-chain transactions, i.e., the number of transactions of the cross-chain transaction is 3. The average processing time for the blockchain network may be determined as follows: t= (w1×t1+w2×t2+w3×t3)/3. Specifically, w1=w2=w3=1.
In an alternative embodiment of step 202, when the processing performance of the blockchain network is transaction confirmation performance of each blockchain in the blockchain network, step 202 may specifically be performed in the following manner:
(1) And for each blockchain of the blockchain network, determining the transaction confirmation duration of each transaction in the blockchain according to the starting time and the uplink time of each transaction started by the plurality of cross-chain transactions on the blockchain.
For the example shown in table 1, the difference between the uplink time 0200 of the transaction with serial number 1 and the initiation time 0100 of the transaction with serial number 1 is 0100, i.e. the transaction confirmation time of the transaction with serial number 1 is 0100.
(2) 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 as follows:
and determining the fluctuation degree of the transaction confirmation time length of the blockchain according to the transaction confirmation time length of each transaction initiated on the blockchain.
For example, the extent of fluctuation 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 extent of fluctuation of the transaction confirmation duration of the blockchain may also be characterized by standard deviation, normalized variance, etc. of the transaction confirmation duration of each transaction of the blockchain, without limitation.
If the fluctuation degree of the transaction confirmation time length of the blockchain is determined to be higher, determining that 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 time length of the blockchain is determined to be low, and the average transaction confirmation time length of the blockchain is not greater than the preset time length, determining that the performance bottleneck of the transaction execution performance in the transaction confirmation performance of the blockchain does not exist.
It should be noted that, the determination method that the fluctuation degree of the transaction confirmation time length of the blockchain is higher or lower may be set according to the specific situation. The fluctuation degree of the transaction confirmation duration of the blockchain is determined according to the variance of the transaction confirmation duration of the blockchain and a preset variance threshold. When the variance of the transaction confirmation time length is larger than a preset variance threshold, determining that the fluctuation degree of the transaction confirmation time length of the blockchain is higher; and when the variance of the transaction confirmation time length is not greater than the preset variance threshold, determining that the fluctuation degree of the transaction confirmation time length of the blockchain is low. When the fluctuation degree of the transaction confirmation time length of the blockchain is large, whether the logic of a specific transaction on the blockchain is too complex or not can be confirmed, bottlenecks are likely to exist, and whether the original logic can be split into a plurality of transactions or whether part of the logic can be distributed to other blockchains is evaluated.
Further, the transaction confirmation time length of each transaction initiated on the blockchain comprises the transaction execution time length of the transaction and the block consensus time length of the transaction; the following steps may also be performed in (2):
if the fluctuation degree of the transaction confirmation time length of the block chain is determined to be low, and the average transaction confirmation time length of the block chain is longer than the preset time length, determining that a bottleneck exists in the transaction confirmation performance of the block chain, and determining a first proportion and a second proportion. If the first proportion is larger than the second proportion, determining that performance bottlenecks exist in the transaction execution performance in the transaction confirmation performance of the blockchain; or if the first proportion is not greater than the second proportion, determining that a performance bottleneck exists in the block consensus performance in the transaction confirmation performance of the block chain.
The first proportion is the ratio of the total transaction execution duration of the blockchain to the total transaction confirmation duration of the blockchain; the second ratio is a ratio of a total block consensus duration of the blockchain to a total transaction confirmation duration of the blockchain. The total transaction execution duration of the blockchain is the sum of the transaction execution durations 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 blockchain is the sum of the block consensus durations of each transaction of the blockchain.
If the fluctuation degree of the transaction confirmation duration of a certain blockchain is smaller and the average transaction confirmation duration of the blockchain is maintained at a larger value (such as larger than the preset duration), the blockchain log is needed to confirm, and if the first proportion and the second proportion are larger, namely the blockchain consensus duration occupies a larger proportion, the problem that the consensus process of the blockchain is abnormal, too many consensus nodes, too complex consensus algorithm or abnormal consensus nodes are likely to exist is solved. If the first proportion is large, namely the transaction execution time length is large, the abnormal transaction execution process of the blockchain is indicated, whether the logic of a specific transaction on the blockchain is too complex or not can be confirmed, bottlenecks are likely to exist, and whether the original logic can be split into a plurality of transactions or part of logic can be distributed to other blockchains is evaluated. .
In an alternative embodiment after step 201, for any blockchain of the blockchain network, determining, according to the number of cross-chain transactions of which the number of blocktransactions is not less than the upper limit of the number of blocktransactions of the blockchain in the execution process of the plurality of cross-chain transactions, the block packing saturation degree of the blockchain. The block transaction number is equal to the upper limit of the block transaction number of the block chain, and the blocks of the block chain are packed
For example, a total of 10 cross-chain transactions are performed. The block transaction number of the block chain is not less than 8 cross-chain transactions of the upper limit of the block transaction number of the block chain, namely, the block chain has 8 times of block packing in the process of executing 10 cross-chain transactions. Specifically, if the blockchain is in the process of executing 10 cross-chain transactions, the blockchain transaction number always reaches the upper limit of the blockchain transaction number, which indicates that the blockchain bears excessive pressure in the process of executing, and the blockchain cannot process all received transactions in time, so that the packaging of the blocks is always in a saturated state; for another example, in the process of executing 10 cross-chain transactions, the blockchain is always lower than the upper limit of the block transaction number of the blockchain, which indicates that the blockchain is not under-pressurized and does not receive enough pressure, so that the block sizes of a plurality of chains in the cross-chain transactions can be coordinated, the load is balanced, and the overall performance of the cross-chain transactions can be improved.
As shown in fig. 6, the present application provides a processing performance analysis apparatus of a blockchain network, including: an execution module 601, configured to execute a plurality of cross-chain transactions on a blockchain network; wherein each of the plurality of cross-chain transactions is a transaction completed by sequentially executing a plurality of transactions on a plurality of blockchains of the blockchain network; the transaction identifiers of the corresponding transactions of each cross-chain transaction are the same; a determining module 602, configured to determine processing performance of the blockchain network according to an initiation time and a uplink time of each transaction in the plurality of cross-chain transactions.
