According to.Further, 101~node of node 104 can be known together based on transaction data, if common recognition passes through, friendship can be generated
Easy corresponding block information；If common recognition does not pass through, node 102 (or may be other nodes) can be to client device
200 send transaction response message, and transaction response message is used to indicate Fail Transaction.
In the embodiment of the present invention, the node in block catenary system can have multiple functions, for example, routing function, transaction
Function, block chain function and common recognition function etc..Specifically, the node in block catenary system can send other nodes
The information such as transaction data send more nodes to realize the communication between node；Alternatively, the node in block catenary system
Can be used for that user is supported to trade；Alternatively, the node in block catenary system can be used for the All Activity on log history；
Alternatively, the node in block catenary system can be by verifying and recording the new block in transaction generation block chain.In practical application,
Routing function is the function that each node in block catenary system must have, and other functions can be by those skilled in the art's root
It is configured according to actual needs.
It should be noted that a node in block catenary system can be on a physical machine (server), and one
Node can specifically refer to a series of process or processes run in server.For example, the node in 1 network of block chain
101 can be the process run on a server, or may be the server referred to where node, not make specifically
It limits.
Based on system architecture illustrated in Figure 1, Fig. 2 is a kind of friendship based on block catenary system provided in an embodiment of the present invention
The corresponding flow diagram of easy to handle method, this method comprises:
Step 201, the mark and clash handle instruction of the first transaction of client device setting.
In the embodiment of the present invention, the first transaction is then can be set if it is determined that need to be implemented the first transaction in client device
Mark.In one possible implementation, client device can be according to business scenario setting first belonging to the first transaction
The mark of transaction, the affiliated business scenario of the first transaction may include business belonging to the first transaction and the first transaction in business
Process (i.e. operation flow).For example, in one example, the execution process of order business may include creation order flow
Journey, storage order process, inquiry order process etc. can be with if operation flow belonging to the first transaction is creation order process
The mark that the order number for using the first transaction creation to obtain is traded as first.Wherein, the length of order number can be by this field
Technical staff is rule of thumb configured, for example can be the data of the variable-length less than or equal to 256 bytes, or can also
The data for thinking regular length, are specifically not construed as limiting.In another example, the execution process of interactive data service may include
Both sides transmit data flow, direction other users transmitting data flow etc., if operation flow belonging to the first transaction is both sides
Data flow is transmitted, then the mark of the first transaction may include the mark of data sender, the mark of data receiver and data
Check value.For example, if the first transaction is user A1To user A2The transaction of data is transmitted, then the mark of the first transaction can wrap
Include user A1Address, user A2Address and data hash value.Wherein, user A1And/or user A2Address can be account
Number name perhaps or mail address or can also be user name is specifically not construed as limiting.
Further, the corresponding clash handle instruction of the first transaction, clash handle instruction can also be arranged in client device
It may include processing mode when the first transaction conflicts with historical trading presence to the first transaction, and/or, the first transaction and history
There is no the processing modes traded when conflict to first for transaction.In one example, the first transaction exists with historical trading conflicts
When to first transaction processing mode may include execute first transaction, by first transaction be redirected to fault-tolerant contract, refusal hold
Any one in the transaction of row first；The processing mode traded when conflicting to first is not present with historical trading for first transaction can be with
Including executing the first transaction.
In one possible implementation, the clash handle instruction that client device is sent may include processing indicated value
And additional data.Table 1 is the schematic table of several possible clash handle instructions provided in an embodiment of the present invention.
Table 1: the signal of several clash handle instructions
| Clash handle instruction | Meaning |
| 1 | Refusal executes |
| 2 | It executes |
| 3:http: //address/0x289 | It is redirected to fault-tolerant contract |
| 4 | Refusal executes and issues alarm |
| 5 | Execution and print log |
| 0 | It executes |
As shown in table 1, it is defined in the embodiment of the present invention at 5 kinds of conflicts that the first transaction exists with historical trading when conflicting
Reason instruction, respectively " 1 ", " 2 ", " 3:http: //address/0x289 ", " 4 ", " 5 ", also define the first transaction and history
There is no a kind of clash handle instructions when conflict for transaction, i.e., " 0 ".Wherein, clash handle instructs " 0 ", " 1 ", " 2 ", " 4 ", " 5 "
Additional data all can be empty, it can be 3 that clash handle, which instructs the processing indicated value of " 3:http: //address/0x289 ",
Additional data can be http://address/0x289.Specifically, conflicting if the first transaction exists with historical trading, and rush
Prominent process instruction is " 1 ", then first node can be refused to execute the first transaction；If the first transaction is with historical trading, there is no punchings
It is prominent, and clash handle instructs to exist for " 0 " or the first transaction with historical trading and conflict, and clash handle instruction is " 2 ", then
First node can execute the first transaction；Conflict if the first transaction exists with historical trading, and clash handle instruction is " 3 ", then
First node can execute the first transaction, and the first transaction can be sent to contract address is http://address/0x289
Fault-tolerant processing device be modified；Conflict if the first transaction exists with historical trading, and clash handle instructs as " 4 ", then the
One node can be refused to execute the first transaction, and can issue warning information；Conflict if the first transaction exists with historical trading, and
Clash handle instruction is " 5 ", then first node can execute the first transaction, and can print the log note of the first transaction conflict
Record, in order to subsequent misarrangement.
It should be noted that being generated in the specially same operation flow of conflict described in the embodiment of the present invention multiple
The conflict of transaction, if the mark of the multiple transaction generated in the same operation flow is identical, multiple transaction can be conflict；
If the mark of the multiple transaction generated in the same process of different business is identical or the different processes of same business in generate
Multiple transaction mark it is identical, then it is multiple transaction do not conflict.For example, transaction B1For business a1Second procedure in
The transaction of generation, trade B2For business a1Second procedure in the transaction that generates, trade B3For business a1First pass in generate
Transaction, trade B4For business a2Second procedure in the transaction that generates, then due to the B that trades1With transaction B3Belong to same business
Different processes, therefore even if transaction B1With transaction B3Mark it is identical, trade B1With transaction B3Also do not conflict；Accordingly, due to friendship
Easy B1With transaction B4Belong to the same process of different business, therefore even if transaction B1With transaction B4Mark it is identical, trade B1With friendship
Easy B4Also do not conflict；And it is directed to transaction B1With B2, due to the B that trades1With transaction B2Belong to the same process of same business, if therefore
Trade B1With transaction B2Mark it is identical, then trade B1With transaction B2Conflict.
For transaction by the first transaction for creation order number, due to needing to guarantee the creation order process of the same business
The order number that middle difference transaction creation obtains is different, therefore order number can be traded with unique identification one；If difference transaction is ordered
Odd numbers is identical, then illustrates that different transaction are conflicts.In order to generate the order number not conflicted, can be set between adjacent transaction
Order number is incremental, or the cryptographic Hash of random number sequence or transaction can also be added in different order numbers.
In the embodiment of the present invention, by the way that client device using business scenario as dimension, can be made to be same business scenario
Transaction use same mark set-up mode so that transaction mark can characterize transaction in same business scenario
Including multiple transaction in uniqueness；That is, mark of the embodiment of the present invention by client device setting transaction, it can
Collision detection is carried out to transaction in a manner of using the mark of comparison transaction, without comparing specific transaction data, so as to
So that the process for carrying out collision detection to transaction is more quick, the efficiency of trading processing in block catenary system is improved；And conflict
Process instruction can be based on practical business scene by client device and be configured, so that trading processing process is more
It corresponds to actual needs.
Step 202, first node of the client device into block catenary system sends transaction request.
Herein, client device can send transaction request to first node in several ways, such as can be by having
Line mode sends transaction request to first node, or can also send transaction request, tool to first node wirelessly
Body is not construed as limiting.
It in one example, may include the mark and clash handle instruction of the first transaction in transaction request.At another
May include in example, in transaction request the first transaction mark, clash handle instruction and first transaction transaction data, first
The transaction data of transaction may include key assignments, account, contract address of the first transaction etc..
Step 203, first node receives the transaction request that client device is sent, and according to the mark of the first transaction, really
The consequences of hostilities of fixed first transaction.
In specific implementation, first node can parse transaction request, obtain the mark and clash handle instruction of the first transaction
(or mark, transaction data and clash handle instruction of the first transaction).Further, first node can be according to the first transaction
Mark, determine the first transaction and historical trading with the presence or absence of conflicting；Wherein, historical trading may include that first node is receiving
The handled whole transaction crossed before to the transaction request of the first transaction.It should be noted that first node is asked in parsing transaction
Before asking, the other nodes that transaction request can also be sent in block catenary system, so that other nodes execute the first transaction,
In this way, multiple nodes in block catenary system can carry out block common recognition process after the transaction of execution first.Other nodes execute
The process that the process of first transaction is referred to the first transaction of first node execution is realized that details are not described herein again.
In the embodiment of the present invention, historical trading be can store in the first presetting database of first node, be based on 1 institute of table
The clash handle of signal instructs, and table 2 is the schematic table of the historical trading stored in the first presetting database of one kind.
Table 2: the signal of the historical trading stored in the first presetting database of one kind
| Transaction ID | Contract address | Key assignments | Transaction Account number | Clash handle instruction | Conflict number |
| a1x1 | http://address/0x755 | 10.33 | Y1 | 1 | 2 |
| a2x2 | http://address/0x733 | 14.24 | Y1 | 0 | 0 |
| a3x3 | http://address/0x555 | 2.56 | Y1 | 3 | 1 |
| a4x4 | http://address/0x755 | 10.33 | Y1 | 4 | 3 |
| a5x5 | http://address/0x765 | 32.54 | Y1 | 2 | 7 |
| a6x6 | http://address/0x755 | 10.33 | Y1 | 0 | 0 |
| a7x7 | http://address/0x736 | 9.56 | Y1 | 1 | 2 |
As shown in table 2, can store in the first presetting database the mark of each historical trading, contract address, key assignments,
Transaction Account number, clash handle instruction and conflict number.For example, transaction is identified as a1x1Historical trading (for ease of description, letter
Referred to as historical trading a1x1) contract address can be http://address/0x755, key assignments can be 10.33, Transaction Account number
It can be Y1, clash handle instruction can for 1 (i.e. the historical trading conflicts with the historical trading presence before the historical trading,
And refused to handle the historical trading), conflict number is 2 (i.e. existing to conflict twice).
It, can be with specifically, the contract address of transaction can be address of the contract on block chain of realizing service logic
For the mark for the business that the data of one section of regular length, the contract address of transaction can belong to for exchange；As shown in table 2, history
Trade a1x1, historical trading a4x4With historical trading a6x6Contract address it is identical, it can be said that bright historical trading a1x1, history hand over
Easy a4x4With historical trading a6x6Affiliated business is identical.Correspondingly, the key assignments of transaction can be for the contract address of transaction and friendship
Easy mark carries out what joint key assignments was calculated, and key assignments can be binary data of the length less than 255 bytes；Based on contract
The key assignments that the mark of address and transaction obtains, can make collision detection process using operation flow as dimension.As shown in table 2, it goes through
History transaction a1x1, historical trading a4x4With historical trading a6x6Key assignments it is identical, it may be said that bright historical trading a1x1, historical trading
a4x4With historical trading a6x6It for the transaction in the same process of the same business, for example can be the process for creating order
In transaction.With historical trading a1x1For, historical trading a1x1Transaction Account number can be by historical trading a1x1Cryptographic Hash table
Show, first node can be according to historical trading a1x1Transaction Account number get historical trading a1x1Transaction Information, for example trade
Initiator, transaction acceptance side, trading processing receipt, affiliated block of trading, the corresponding block information of transaction etc..Historical trading
a1x1Clash handle instruction can refer to send historical trading a1x1The clash handle of client device configuration instructs, and conflicts
Before number can refer to the transaction request for receiving the first transaction, historical trading a1x1With the history in the first presetting database
There is the number of conflict, every determining historical trading a in transaction1x1Conflict is primary, then can be by historical trading a1x1Conflict number add
1。
In one possible implementation, in the mark and the first presetting database that first node can trade will first
The marks of one or more historical tradings compare, however, it is determined that there is the mark with the first transaction in the first presetting database
Matched historical trading can then determine that the first transaction exists with historical trading and conflict；If it is determined that in the first presetting database not
In the presence of the matched historical trading of mark with the first transaction, then can determining the first transaction, there is no conflict with historical trading.With
For the first presetting database that table 2 is illustrated, if the first transaction is identified as a1x1, then the first transaction and history can be determined
There is conflict in transaction, if the first transaction is identified as a8x8, then can determining the first transaction, there is no conflict with historical trading.
In this implementation, by directly by the mark of the first transaction and the historical trading in the first presetting database
Mark compares, and can determine that the first transaction whether there is with historical trading by a wheel collision detection process and conflicts, from
And can simplify the process of collision detection, it is easy to implement.
In alternatively possible implementation, first node can successively execute first round collision detection to the first transaction
A wheel collision detection or mostly wheel collision detection in the collision detection of~third round, wherein first round collision detection is rushed with the second wheel
The process of prominent detection can be executed in default memory headroom, and the process of third round collision detection can be in the first preset data
It is executed in library.First round collision detection~third round collision detection realization process is detailed below.
First round collision detection
In specific implementation, first node can obtain the contract address of the first transaction from the transaction data of the first transaction,
And then can be carried out by joint key assignments and calculated for the mark of the first transaction and the contract address of the first transaction, obtain the key of the first transaction
Value, and can obtain from the first presetting database and trade with the target histories of the key value match of the first transaction；For example, join
According to the first presetting database that table 2 is illustrated, if the key assignments of the first transaction is 10.33, target histories transaction may include going through
History transaction a1x1, historical trading a4x4With historical trading a6x6.Further, the mark that first node can trade target histories
Store default memory headroom, or all information that the target histories stored in the first presetting database can also be traded
Default memory headroom is arrived in (i.e. transaction ID, contract address, key assignments, Transaction Account number, clash handle instruction and conflict number) storage,
Specifically it is not construed as limiting.When executing first round collision detection, first node can be empty by the mark of the first transaction and default memory
Between the mark of target histories transaction of middle storage compare, however, it is determined that there is the mark with the first transaction in default memory headroom
Matched target histories transaction can then determine that the first transaction exists with historical trading and conflict；If it is determined that in default memory headroom
There is no the matched target histories of mark with the first transaction to trade, then can execute the second wheel collision detection.
In first round collision detection, due to the key assignments of target histories transaction and the key value match of the first transaction, mesh
Marking historical trading and the first transaction can be the transaction in the same process of the same business.On the one hand, by based on the
The identical target histories transaction of operation flow belonging to one transaction carries out first round collision detection to the first transaction, it is possible to reduce punching
The number that transaction is compared in prominent detection process, improves the efficiency of collision detection.On the other hand, by the way that target histories are traded in advance
Default memory headroom is stored, the process that comparison can be made to trade executes in default memory headroom, without pre- first
If being executed in database, so as to improve the response speed of collision detection process.
In the embodiment of the present invention, first round collision detection can be adapted for the biggish scene of possibility that conflicts, if the first round
The testing result of collision detection is conflict, then can determine that the first transaction exists with historical trading and conflict, by executing the first round
Collision detection, the biggish transaction of the possibility that can will conflict detected, look into so as to be reduced in the first presetting database
The number for asking historical trading improves the calculating speed of collision detection, saves overhead.
Second wheel collision detection
In the embodiment of the present invention, the first default filtering model is also provided in the first presetting database, if first segment
Point receives the transaction request of the first transaction of client device transmission, then the stored in available first presetting database
One default filtering model, and by the first default filtering model storage into default memory headroom.Correspondingly, if first round conflict inspection
The testing result of survey does not conflict for the first transaction with historical trading, and (there is no the marks with the first transaction in i.e. default memory headroom
The transaction of matched target histories), then the mark of the first transaction can be input to by first node stores in default memory headroom
In first default filtering model.
Further, the first default filtering model can execute the second wheel collision detection to the first transaction, and can export
The consequences of hostilities of first transaction；The consequences of hostilities of first transaction can be any one in the first result and the second result, the
One result is used to indicate the first transaction with historical trading there is no conflicting, and the second result is used to indicate the first transaction and historical trading
There may be conflicts.In this way, after the first transaction is inputted the first default filtering model by first node, if output result is the first knot
Fruit, then can determining the first transaction, there is no conflict with historical trading；If output result be second as a result, if can execute third
Take turns collision detection.
In specific implementation, the model structure of the first default filtering model can rule of thumb be carried out by those skilled in the art
Setting, is specifically not construed as limiting.As an example, the first default filtering model can be the model obtained based on bit, than
Such as Bloom filter；It is found according to experiment, if the memory of Bloom filter is smaller, will increase and output result is mistaken for the second knot
The probability of fruit will cause the waste of system space if the memory of Bloom filter is larger.Therefore, the embodiment of the present invention is by real
Test determination, by the memory setting of Bloom filter be 200M and based on the historical trading in nearest 3 years Transaction Information (including
Mark, key assignments, transaction data, clash handle instruction, conflict number of historical trading etc.) when being trained to Bloom filter,
The False Rate of output result of Bloom filter can be made less than 1%.By be arranged Bloom filter memory size and
The historical trading of training Bloom filter, can not only save system space, but also can be improved the accuracy of output result.
It should be noted that above-mentioned is only a kind of illustrative simple declaration, those skilled in the art can also be according to reality
Border needs to be arranged the memory of Bloom filter and/or the historical trading of training Bloom filter, above-mentioned setting are not constituted to this
The restriction of scheme.In specific implementation, the memory of Bloom filter can be greater than 200M, or might be less that 200M, such as
It can be 400M or 100M；Correspondingly, the historical trading of training Bloom filter can be the historical trading in nearest 2 years, or
Person may be the historical trading in recent five years, specifically be not construed as limiting.
In the embodiment of the present invention, the second wheel collision detection can be adapted for the lesser scene of possibility that conflicts, if the second wheel
The testing result of collision detection is not conflict, then can determine that the first transaction and historical trading there is no conflicting, pass through execution the
Two wheel collision detection, the lesser transaction of the possibility that can will conflict detected.In the embodiment of the present invention, to the first present count
Conflict is taken turns based on the first round collision detection and second in default memory headroom according to being first passed through before executing collision detection in library in advance
Detection, the consequences of hostilities of available most of transaction are traded so as to be reduced to query history in the first presetting database
Number, improve the calculating speed and efficiency of collision detection, save overhead.
Third round collision detection
If the output result of the second wheel collision detection is that the first transaction conflicts (the i.e. first default filtering model with historical trading
The result of output, which exists for the first transaction with historical trading, to conflict), then first node can execute third round collision detection.Specifically
Ground says that first node can compare the mark of the mark of the first transaction and the historical trading in the first presetting database,
If it is determined that in the first presetting database exist with first transaction the matched historical trading of mark, then can determine the first transaction with
There is conflict in historical trading；If it is determined that the matched historical trading of mark with the first transaction is not present in the first presetting database,
Can then determining the first transaction, there is no conflict with historical trading.
In the embodiment of the present invention, it can be detected out by using first round collision detection and the second wheel collision detection most of
Conflict transaction, due to first round collision detection and the second wheel collision detection be executed in default memory headroom, thus
Response speed can be made very fast, improve the efficiency of collision detection.And third round collision detection can be adapted for any scene,
If not obtaining the consequences of hostilities of the first transaction based on first round collision detection and the second wheel collision detection, third can be based on
Wheel collision detection compares the first transaction with the historical trading in the first presetting database, so as to obtain the first transaction
Consequences of hostilities.It, can be to avoid direct by using first round collision detection~third round collision detection in the embodiment of the present invention
Into the first presetting database query history trade, so as to reduce overhead, improve collision detection efficiency while,
Obtain accurate consequences of hostilities.
Step 204, first node is instructed according to the consequences of hostilities and clash handle of the first transaction, at the first transaction
Reason, obtains the processing result of the first transaction.
The clash handle instruction illustrated according to table 1, table 3 are consequences of hostilities and conflict of the first node according to the first transaction
The schematic table for several processing modes that process instruction executes the first transaction.
Table 3: the signal of the several ways of the first transaction of first node processing
As shown in table 1 and table 3, if the consequences of hostilities of the first transaction and clash handle instruction meet the first as follows
Any condition in condition~four kind condition, then first node can execute the first transaction:
The first condition, consequences of hostilities be the first transaction with historical trading there is no conflict, and it is that clash handle, which instructs,
There is no the first transaction (i.e. " 0 ") is executed when conflicting with historical trading for one transaction；
Second of condition, consequences of hostilities, which exists for the first transaction with historical trading, to conflict, and clash handle instruction is first
Transaction exists with historical trading executes the first transaction (i.e. " 2 ") when conflicting；
The third condition, consequences of hostilities, which exists for the first transaction with historical trading, to conflict, and clash handle instruction is first
Transaction exists with historical trading is redirected to fault-tolerant contract (i.e. " 3 ") for the first transaction when conflicting；
4th kind of condition, consequences of hostilities, which exists for the first transaction with historical trading, to conflict, and clash handle instruction is first
Transaction exists with historical trading executes the first transaction and print log (i.e. " 5 ") when conflicting.
It should be noted that if the consequences of hostilities of the first transaction and clash handle instruction meet the third condition, then first
Node can handled first transaction after, generate the first log, and processing first can be traded timestamp information, transaction
Data and conflict indicated value are added in the first log, and then save the first log, in order to which operation maintenance personnel executes misarrangement work.
Correspondingly, if the consequences of hostilities of the first transaction and clash handle instruction meet as follows the 5th kind of condition or the
Six kinds of conditions, then first node can be refused to execute the first transaction:
5th kind of condition, the first transaction exists with historical trading to conflict, and clash handle instruction is the first transaction and history
Refusal executes the first transaction (" 1 ") when transaction has conflict；
6th kind of condition, the first transaction exists with historical trading to conflict, and clash handle instruction is the first transaction and history
Refusal executes the first transaction when transaction has conflict, and alerts (i.e. " 3 ").
It should be noted that if the consequences of hostilities of the first transaction and clash handle instruction meet the 6th kind of condition, then first
Node can generate warning information, and can send a warning message to client device while refusal the first transaction of processing,
In order to which operation maintenance personnel executes misarrangement work.
The specific implementation process of the first transaction of first node processing is described from two kinds of situations separately below.
Situation one
In situation one, first node can execute the first transaction, i.e., the consequences of hostilities and clash handle of the first transaction refer to
Order meets the first above-mentioned condition, perhaps meets second of condition and perhaps meets four kind article of the third condition or satisfaction
Part.
In one example, first node, then can be first to including if it is determined that execute the first transaction in default memory headroom
Target histories transaction be updated.In one example, if there is no the mark phases with the first transaction in default memory headroom
Same historical trading, then the first transaction can be added in default memory headroom by first node, in this way, in default memory headroom
Including target histories transaction in may include the first transaction, if first node execution first trade during receive with
Identical second transaction of the mark of first transaction can determine the second transaction and the first transaction then by first round collision detection
Conflict, so as to without executing and duplicate second transaction of the first transaction.In another example, if in default memory headroom
It trades in the presence of target histories identical with the mark of the first transaction, then first node can update the mesh stored in presetting database
Mark the information of historical trading, for example the conflict number of target histories transaction, clash handle instruction can be updated etc., in this way, can be with
So that the default filtering model determined based on the historical trading in default memory headroom is more accurate.In the embodiment of the present invention, lead to
It crosses and is determining that memory headroom is preset in update when executing the first transaction, can make the trading processing process of first node more efficient.
Further, first node can be communicated with other nodes in block catenary system, execute the first transaction
Common recognition process, however, it is determined that the quantity for the node reached common understanding in block catenary system to the first transaction is greater than or equal to preset threshold,
The corresponding block information of the first transaction then can be generated, and it is default that the corresponding block information update first of the first transaction can be used
Database and/or default memory headroom, for example the first presetting database can be updated according to the block information of the first transaction, or
Default memory headroom can also be updated according to the block information of the first transaction, or can also be according to the block information of the first transaction
The first presetting database and default memory headroom are updated, is specifically not construed as limiting.Correspondingly, however, it is determined that first in block catenary system
The quantity for the node that transaction is reached common understanding is less than preset threshold, then can send to client device and execute the first Fail Transaction
Message.Wherein, preset threshold can be rule of thumb arranged with capable field technique personnel, such as can be for included by block catenary system
Number of nodes 3/4, be specifically not construed as limiting.
In the embodiment of the present invention, generate the first corresponding block information of transaction mode can there are many, in a kind of possibility
Implementation in, can store the first check value in the first presetting database, the first check value can make for first node
Multiple historical tradings are verified with default checking algorithm, for example can be the cryptographic Hash of multiple historical tradings.Tool
During body is implemented, before determining the first transaction of execution, first node can obtain the first check value from the first presetting database,
And the first check value can be stored in default memory headroom；Further, during execution first is traded, first segment
Point can pre-generate the corresponding original block information of the first transaction, and can be used default checking algorithm to the first check value and
First transaction is verified, and the second check value is obtained；Further, the second check value can be added to original area by first node
In block message, and it can know together with other nodes in block catenary system, if common recognition passes through, available first transaction
Corresponding block information, and the second check value can be used and update the first check value stored in default memory headroom.
In one example, the second check value can be determined using circulation hash algorithm, program implement can be as
Shown in lower:
According to the first row program, first node, which determines, executes transaction data [0], historical trading data [1] and historical trading
data[2]；According to second stroke sequence, the check value HASH_NEW that is stored in the available default memory headroom of first node；Root
According to the third line~fourth line program, first node can take cryptographic Hash to transaction data [0], obtain the verification of transaction data [0]
Value hash (Data [1]), and then can be to the check value hash (Data of the first check value HASH_NEW and transaction data [0]
[1]) cryptographic Hash is taken, the check value of the historical trading including transaction data [0] is obtained；Correspondingly, first node can root
Check value and transaction data [1] according to the historical trading including transaction data [0] obtain including trading data [0] and handing over
The check value of historical trading including easy data [1], and then can be according to including transaction data [0] and transaction data [1]
Historical trading check value and transaction data [2], obtain include transaction data [0], transaction data [1] with trade data [2]
The check value of historical trading inside；According to fifth line program, it can be used including transaction data [0], transaction data [1] and hand over
The check value of historical trading including easy data [2] updates the check value of the historical trading stored in default memory headroom.
It should be noted that above-mentioned is only a kind of illustrative simple declaration, cited by using circulation hash algorithm
It determines that the mode of the second check value is merely for convenience and purposes of illustration of scheme, does not constitute the restriction to scheme.In specific implementation, really
The mode of fixed second check value can be rule of thumb configured by those skilled in the art, for example can use merkle
Root algorithm determines the second check value, or can determine the second check value using acyclic hash algorithm, is specifically not construed as limiting.
In the embodiment of the present invention, the first check value can be used for identifying the handled historical trading crossed of block catenary system, lead to
It crosses after the transaction of execution first, updates the first check value using the first transaction and obtain the second check value, on the one hand, area can be made
Multiple nodes in block catenary system are based on identical second check value and realize common recognition, to improve trading processing in block catenary system
Accuracy；On the other hand, it can make block catenary system during handling transaction locating for real-time update block catenary system
The historical trading managed, to improve the accuracy of subsequent processing transaction.
If first node successful execution first is traded, the corresponding block information of the first transaction can be stored in block chain
In system, in this way, the processing result of the first transaction may include the corresponding block information of the first transaction.Further, first segment
Point, which can be used, updates the first presetting database and/or default memory headroom according to the block information of the first transaction.In a kind of possibility
Implementation in, mark the first default filtering model of training of the first transaction can be used in first node, and it is default to obtain second
Filtering model, and the store in the first presetting database first default filtering model can be updated to the second default filter module
Type；And the corresponding Transaction Information of the first transaction can be added in the first presetting database by first node, and can be used
It states and determines that the second obtained check value updates the first check value stored in the first presetting database；Further, first node
The second default filtering model and the second check value can be used and update the default filtering of first stored in default memory headroom respectively
Model and the first check value.
Correspondingly, if first node executes the first transaction (for example node common recognition does not pass through) not successfully, the first transaction
Processing result may include the first instruction information, and the first instruction information is used to indicate the failure of the first trading processing.In an example
In, since first node is when determining that executing first trades, i.e., the first transaction is added in default memory headroom, therefore,
If executing the first transaction not successfully, first node can be deleted the store in default memory headroom first transaction, so as to
It can not guarantee subsequent friendship by first round collision detection to avoid subsequent transaction identical with the mark of the first transaction getting
Tractable accuracy.
In the embodiment of the present invention, the first presetting database is successively updated by using the block information of the first transaction and is preset
The check value of the first default filtering model, historical transactional information and historical trading in memory headroom, can be using based on update
Default memory headroom and the first presetting database afterwards carries out collision detection to next transaction, so as to improve collision detection
Accuracy.
It should be noted that if the consequences of hostilities of the first transaction and clash handle instruction meet above-mentioned 4th kind of condition, then
First node can also obtain the address for the fault-tolerant contract for including in transaction request, and can basis after the transaction of execution first
The call by location fault-tolerant processing module of fault-tolerant contract is modified the first transaction.In this way, in the processing result of the first transaction also
It may include the address of fault-tolerant contract, the address of fault-tolerant contract is for calling the fault-tolerant processing module in client device to first
Transaction is modified.
Situation two
In situation two, first node can refuse execution first and trade, i.e., at the consequences of hostilities of the first transaction and conflict
Reason instruction can satisfy above-mentioned 5th kind of condition or above-mentioned 6th kind of condition.
In specific implementation, if first node refusal executes the first transaction, conflict indication code is can be generated in first node, is rushed
Prominent indication code is used to indicate the first transaction and conflicts with historical trading presence, and first node is not carried out the first transaction.Therefore, first
It may include conflict indication code in the processing result of transaction.
Step 205, first node sends the first information or the second information to client device.
In specific implementation, first transaction processing result may include the block information of the first transaction, first instruction information,
Any one or any multinomial to conflict in the address of indication code, fault-tolerant contract.If the processing result of the first transaction includes first
The address of the block information of transaction and/or fault-tolerant contract, illustrate the first transaction by first node successful execution, then first node
The first information can be sent to client device；If the processing result of the first transaction includes the first instruction information or conflict instruction
Code illustrates the first transaction not by first node successful execution, then first node can send the second information to client device.
In the embodiment of the present invention, there is " first node and historical trading in the clash handle instruction of client device setting
The first transaction of execution when in the presence of conflict ", " first node is redirected to fault-tolerant module when existing and conflict with historical trading " and " first
Node exists with historical trading executes the first transaction and print log when conflicting " these three situations, i.e., the first transaction and history are handed over
The first transaction may also be by first node successful execution when easily there is conflict.Therefore, in order to avoid there are biggish for the first transaction
Business fault, first node can send the first information to client device after the transaction of successful execution first.In an example
In, it may include block information and/or the address of fault-tolerant contract of the first transaction in the first information, in this way, client device connects
After the first information, the first transaction can be modified according to the first information.
Correspondingly, if the processing result of the first transaction includes the first instruction information, illustrate that the first transaction has passed through conflict
Detection, but not by first node successful execution；If the processing result of the first transaction includes conflict indicated value, illustrate the first transaction
It is not instructed by clash handle, and not by first node successful execution.Since the first transaction is not successfully executed, will not deposit
It makes mistakes in biggish business, therefore, first node can send the second information to client device, and the second information can be used for referring to
Show that the first transaction is not successfully executed.
Step 206, client device receives the first information or the second information that first node is sent, and calls fault-tolerant processing
Module is modified the first transaction.
It can be set the second presetting database in specific implementation, in client device, it can be in the second presetting database
It is stored with the processed whole historical tradings of client device.In one possible implementation, if client device receives
The first information sent to first node then illustrates the first transaction by first node successful execution, in this way, client device can
To carry out collision detection to the first transaction based on the second presetting database, determines the first transaction and client device is processed goes through
History transaction is with the presence or absence of conflict.In one example, client device can directly preset the mark that first trades with second
The mark of the historical trading stored in database compares, and determines the first transaction and the processed historical trading of client device
With the presence or absence of conflict；In another example, client device can to first transaction successively execute first round collision detection~
Third round collision detection conflicts so that it is determined that the first transaction whether there is with the processed historical trading of client device.Herein,
Above-mentioned two example is referred to determine the first transaction with the processed historical trading of first node with the presence or absence of punching in step 203
Prominent process is realized, is specifically repeated no more.
Further, if the matched historical trading of mark of mark with the first transaction is not present in the second presetting database,
Untreated transaction identical with the mark of the first transaction before then illustrating client device；In this way, client device can incite somebody to action
First transaction is added in the second presetting database.Correspondingly, if there is mark and the first transaction in the second presetting database
Matched historical trading is identified, then processed transaction identical with the mark of the first transaction before illustrating client device；Such as
This, client device can be used fault-tolerant processing module and be modified according to default processing rule to the first transaction.Wherein, it presets
Processing rule may include output journal record, the transaction record of the second presetting database of output, invalid transaction, revocation trade,
Freeze any one or any multinomial in subsequent transaction.
In specific implementation, fault-tolerant processing module can prejudge operation flow belonging to the first transaction, however, it is determined that first
Transaction is the transaction in non-key type operation flow, then fault-tolerant processing module can repair the first transaction using various ways
Just.In one example, the log information and/or database information of available first transaction of fault-tolerant processing module, and can be with
The log information of first transaction and/or database information are sent to operation maintenance personnel and safeguarded；In another example, fault-tolerant
Processing module can carry out the first transaction according to the default processing rule being arranged in fault-tolerant contract according to the address of fault-tolerant contract
Subsequent processing.Influence due to the transaction in nonessential operation flow to business is smaller, using aforesaid way to non-pass
Transaction in keyness operation flow is modified, and the treatment effeciency of system can be improved.
Correspondingly, however, it is determined that the first transaction is the transaction in crucial type operation flow, then fault-tolerant processing module can basis
Operation flow belonging to first transaction is modified the first transaction.For example, if the first transaction is held to create new order X
Wrong processing module can set invalid state for the state of order X；If the first transaction is in account Q1Middle addition income L1, then
Fault-tolerant processing module can be from account Q1On subtract income L1；If the first transaction is account Q1To account Q2Money transfer L2, then hold
Wrong processing module can be by account Q2Fund L in upper retracts account Q1；If the first transaction is to repeat from account Q3In abnormally
Assets N is marked, then fault-tolerant processing module can be by account Q3Freeze.
It should be noted that above-mentioned is only a kind of illustrative simple declaration, cited by the first transaction is repaired
Positive mode is merely for convenience and purposes of illustration of scheme, does not constitute the restriction to scheme.In specific implementation, the first transaction is carried out
Modified mode can be rule of thumb configured by those skilled in the art, or can be set according to actual business requirement
It sets, is specifically not construed as limiting.
In the embodiment of the present invention, since clash handle instruction is client device setting, it is thus possible to can exist certain
The transaction clashed is still processed, by sending block information to client device after having handled transaction, can make
Client device is modified transaction, so as to avoid trading processing process from biggish fault occur, improves block linkwork
The traffic handing capacity of system and the accuracy of business processing.
In alternatively possible implementation, if client device receives the second information of first node transmission,
Fault-tolerant processing module can be called to obtain the relevant information of the first transaction, such as timestamp, the transaction data, conflict of the first transaction
As a result instructed with clash handle etc.；Further, fault-tolerant processing module can be by the relevant information storage of the first transaction to log
In the information of information or data library, so that operation maintenance personnel carries out misarrangement according to log information or database information.
In the above embodiment of the present invention, the first node in block catenary system receives the transaction that client device is sent and asks
It asks, transaction request includes the mark and clash handle instruction of the first transaction, and clash handle instruction includes that the first transaction is handed over history
Easily there is the processing mode traded when conflict to first, and/or, there is no hand over when conflicting first with historical trading for the first transaction
Easy processing mode；Further, first node determines the consequences of hostilities of the first transaction, and root according to the mark of the first transaction
Consequences of hostilities and clash handle instruction according to the first transaction, handle the first transaction；Wherein, the consequences of hostilities of the first transaction
The first transaction and historical trading are used to indicate with the presence or absence of conflicting.It, can be with by the mark of setting transaction in the embodiment of the present invention
Using comparison transaction mark by the way of to first transaction carry out collision detection, without compare transaction data, so as to so that
Obtain, in the raising block catenary system efficiency of trading processing more quick to the process of transaction progress collision detection；And due to conflict
Process instruction is configured by client device, therefore can be arranged based on the requirement of different business scenario and client device
Different clash handle instruction, that is to say, that the transaction processing method in above-mentioned technical proposal is more in line with actual conditions.
Based on system architecture illustrated in Figure 1 and transaction processing method illustrated in Figure 2, Fig. 3 mentions for the embodiment of the present invention
The structural schematic diagram of a kind of client device and first node that supply.As shown in figure 3, conflict inspection can be set in first node
Unit, transaction execution unit and updating unit are surveyed, it can be successively between collision detection unit, transaction execution unit and updating unit
Connection.And default memory headroom, the first default filtering model and the first presetting database are also provided in first node；
Correspondingly, the second presetting database can be set in client device.
It can be as following to the first process for being handled of transaction based on client device and first node illustrated in Figure 3
Shown in step 1~step 6:
Step 1, client device is arranged into first node collision detection unit sends transaction request, in transaction request
The clash handle of mark and the first transaction including the first transaction instructs.
Step 2, after collision detection unit receives the transaction request that client device is sent, the mark of the first transaction is obtained,
And based on any one or any number of in default memory headroom, the first default filtering model and the first presetting database
One transaction carries out collision detection.For example, in one example, collision detection unit can be based only upon default memory headroom to first
Transaction carries out collision detection, is perhaps based only upon the first default filtering model and carries out collision detection to the first transaction or be based only upon
First presetting database carries out collision detection to the first transaction；In another example, collision detection unit can be based on default
Memory headroom and the first default filtering model carry out collision detection to the first transaction, or pre- based on default memory headroom and first
If database carries out collision detection to the first transaction, or based on the first default filtering model and the first presetting database to first
Transaction carries out collision detection；In yet another example, collision detection unit can be based on default memory headroom, the first default filtering
Model and the first presetting database carry out collision detection to the first transaction.
In one possible implementation, collision detection unit can execute the first transaction based on default memory headroom
First round collision detection.If first round collision detection is determined in default memory headroom and is gone through in the presence of the mark traded with first is matched
History transaction, then collision detection unit can determine that the first transaction exists with historical trading and conflict；If first round collision detection determines
There is no the matched historical tradings of mark with the first transaction in default memory headroom, then collision detection unit can be based on first
Default filtering model executes the second wheel collision detection to the first transaction.If the second wheel collision detection determines that the first transaction and history are handed over
Easily there is no conflicts, then collision detection unit can determine that the first transaction is not present with historical trading and conflict；If the second wheel conflict
Detection determines that the first transaction exists with historical trading and conflicts that then collision detection unit can be based on the first presetting database to first
Transaction executes third round collision detection.If third round collision detection determines the mark existed in the first presetting database with the first transaction
Know matched historical trading, then collision detection unit can determine that the first transaction exists with historical trading and conflict；If the first round rushes
The matched historical trading of mark traded with first is not present in prominent detect in determining first presetting database, then collision detection unit
Can determining the first transaction, there is no conflict with historical trading.
Conflict if it is determined that the first transaction exists with historical trading, and clash handle instruction is " the first transaction and historical trading
Refusal executes the first transaction when in the presence of conflict ", then first node and client device can execute following steps 3.1 and step
4.1:
Step 3.1, collision detection unit (or first node) sends conflict indication code to client device.
Step 4.1, client device receives the conflict indication code that collision detection unit is sent, and calls fault-tolerant processing module
Clash handle is carried out to the first transaction.In one example, the timestamp of available first transaction of fault-tolerant processing module, transaction
Data and conflict indication code, and log information can be recorded in the timestamp of the first transaction, transaction data and conflict indication code
Or in database.
Correspondingly, however, it is determined that the first transaction with historical trading there is no conflict, and clash handle instruction for " first trade and
There is no the first transaction is executed when conflict for historical trading " or the first transaction with historical trading in the presence of conflicting, and clash handle refers to
It enables existing for " the first transaction executes the first transaction when existing with historical trading and conflicting " or the first transaction with historical trading and rush
It is prominent, and clash handle instruction is " the first transaction is redirected to fault-tolerant processing module in the presence of when conflicting with historical trading ", then first
Node and client device can execute following steps 3.2, step 4.2~step 6, step 4.1:
Step 3.2, the first transaction is sent to transaction execution unit by collision detection unit, so that transaction execution unit executes
First transaction.
In specific implementation, transaction execution unit can be used intelligent contract and execute the first transaction, and can by network with
Other nodes in block catenary system are known together.If the quantity for the node reached common understanding is greater than or equal to preset threshold, hand over
The corresponding block information of the first transaction can be generated in easy execution unit, and the corresponding block information storage of the first transaction can be arrived
In the block chain of bottom；If the quantity for the node reached common understanding is less than preset threshold, execution unit of trading (or first node)
The information that the first transaction executes failure can be sent to client device, so that client device calls fault-tolerant processing resume module
First transaction (process is not shown in FIG. 3).
Step 4.2, it after transaction execution unit determines that successful execution first is traded, is sent to updating unit and updates request, more
It include the corresponding block information of the first transaction in new request.
Step 5, after updating unit receives the update request that transaction execution unit is sent, the corresponding area of the first transaction is used
Block message updates default memory headroom, the first default filtering model and the first presetting database.Specifically, updating unit can be with
First transaction is added in default memory headroom and the first presetting database, and can be based on including in the first presetting database
Historical trading and first transaction update the first default filtering model.
Step 6, first node is if it is determined that default memory headroom, the first default filtering model and the first presetting database update
It completes, then sends transaction response message to client device, include the corresponding block information of first node in response message of trading.
As shown in figure 3, the second presetting database can be set in client device, if client device receives first
The corresponding block information of node can then obtain the mark of first node, Jin Erke from the corresponding block information of first node
The mark of first node to be matched with the multiple historical tradings stored in the second presetting database.If it is determined that second is default
There is no historical tradings identical with the mark of the first transaction in database, then the first transaction can be added to by client device
In second presetting database；If it is determined that there is historical trading identical with the mark of the first transaction in the second presetting database, then
Client device can call fault-tolerant processing module to be modified the first transaction, and specific implementation process is referred to step 206
