Specific embodiment

It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, and It is not used in restriction the application.

Fig. 1 is the applied environment figure of contract data process method in one embodiment.Referring to Fig.1, the contract data process Method is applied to contract data process system.The contract data process system includes terminal 110 and server 120.110 He of terminal Server 120 passes through network connection.Terminal 110 specifically can be terminal console or mobile terminal, and mobile terminal specifically can be with hand At least one of machine, tablet computer, laptop etc..Server 120 can use independent server either at least one The server cluster of a server composition is realized.Wherein, server 120 is a node, and one is preserved in node completely Block chain, block chain includes at least one block.

Specifically, at least one transaction to be processed is sent to server 120 by transaction request by terminal 110.Server 120 receive transaction request, obtain the corresponding intelligent contract method of each transaction to be processed according to transaction request, create object block Corresponding piece of caching, creation initial transaction corresponding with each transaction to be processed cache, in each initial transaction caches parallel Corresponding intelligent contract method is executed, the corresponding more New Transaction caching of each transaction to be processed is obtained, successively will by trading order Each more New Transaction caching is incorporated into block caching, when current more New Transaction caching to be combined has merged friendship with the history in block caching When easy data cached No Assets conflict, current more New Transaction caching to be combined is incorporated into block caching, when it is current it is to be combined more It is data cached there are when resource contention that New Transaction caching has merged transaction with the history in block caching, then is cached based on block and created again Corresponding intermediate transaction caching is built, transaction caching executes the corresponding intelligence contract side of current more New Transaction caching to be combined in centre The corresponding transaction caching of implementing result is incorporated into block caching by method, until each corresponding more New Transaction caching to be processed of trading It is incorporated into block caching and obtains object block caching, cached according to object block and generate update block.

As shown in Fig. 2, in one embodiment, providing a kind of contract data process method.The contract data process side Method can be executed by computer equipment, and computer equipment can be at least one of server or terminal.The present embodiment is main It is applied to the server 120 in above-mentioned Fig. 1 in this way to illustrate.Referring to Fig. 2, which is specifically wrapped Include following steps:

Step 202, transaction request is received, transaction request includes at least one transaction to be processed.

Wherein, transaction request is usually to send transaction request to service by terminal for requesting to handle transaction to be processed In device, after server receives transaction request, corresponding transaction to be processed can be handled according to transaction request.Wherein, transaction request Including at least one transaction to be processed, the transaction to be processed such as transaction to be processed is.Wherein, transaction to be processed presence pair here Intelligent contract method is answered, there are the transaction to be processed of corresponding intelligent contract method can create corresponding initial transaction caching, and There is no the transaction to be processed of corresponding intelligent contract method without creating corresponding initial transaction caching.

Specifically, terminal can generate transaction request by related application or control triggering, by least one friendship to be processed Easy corresponding Transaction Information is carried into transaction request, is sent to server by network.

Step 204, the corresponding intelligent contract method of each transaction to be processed is obtained according to transaction request.

Wherein, intelligent contract and block chain are closely related, and block chain is Distributed Storage, point-to-point transmission, common recognition The new application mode of the computer technologies such as mechanism, Encryption Algorithm, block chain are substantially the databases of a decentralization, together When Floor layer Technology of the block chain as bit coin, be a string using the associated data blocks generated of cryptography methods, each number According to the information of a batch bit coin network trading is contained in block, for verifying the validity (anti-fake) of its information and generating next A block.And intelligent contract is that block chain is referred to as " decentralization " major reason, it allows not needing third-party feelings Under condition, traceable, irreversible and safe transaction is executed.

Wherein, it is a kind of computer protocol used in block chain technology, intelligent contract packet that intelligent contract, which is intelligent contract, All information for having contained at least one transaction to be processed just understand implementing result operation only after meeting the requirements.And intelligent contract Including at least one variable and corresponding contract method, intelligent contract method here refers to the contract side in intelligent contract Method.

Specifically, after server receives transaction request, the corresponding intelligence of each transaction to be processed is obtained according to transaction request It can contract method.It specifically can be, corresponding variable determined according to each transaction to be processed, determines corresponding conjunction further according to variable About method, using the corresponding contract method of variable as corresponding corresponding intelligent contract method to be processed of trading.

Step 206, corresponding piece of object block caching is created, creation initial transaction corresponding with each transaction to be processed is delayed It deposits.

Wherein, object block is cached for creating block, and object block can be determined from block, for example, object block can be with It is newest block, so-called newest block refers to the highest block of height in the block of server preservation.And block caching is for delaying Deposit transaction to be handled corresponding transaction results, and initial transaction caching is for caching each transaction execution pair to be processed The transaction results that the intelligent contract method answered generates.Each transaction to be processed is when executing corresponding intelligent contract method, intelligence Change brought by energy contract method can all be cached into corresponding initial transaction caching, and each transaction to be processed executes correspondence Intelligent contract method generate transaction results it is all combinable to block caching in.Need to be located that is, temporarily saving in block caching The corresponding transaction results of reason transaction.

Specifically, block caching can cache newest block based on contract and create to obtain, and newest block refers to that server is protected The highest block of height in the block deposited can be each transaction creation to be processed based on block caching after creation obtains block caching Corresponding initial transaction caching.Here contract caching refers to for saving the corresponding intelligent contract method of each transaction to be processed , after obtaining corresponding intelligent contract method in database, the intelligent contract method that will acquire is united for each transaction to be processed One, which is put into contract caching, saves.Wherein, contract caching includes contract read buffer and contract write buffer, and contract read buffer is used to record The read access situation of intelligent contract method, contract write buffer are used to record the write access situation of intelligent contract method.

It in one embodiment, is that newest block creates the corresponding read and write cache of block caching based on contract caching, Read and write cache again based on block caching, which is that the corresponding initial transaction caching of each transaction creation to be processed is corresponding, to be read to delay It deposits and write buffer.Wherein, transaction to be processed caches corresponding read and write cache in corresponding initial transaction and executes respectively pair The intelligent contract method answered, what the corresponding transaction results of read buffer and initial transaction for respectively obtaining initial transaction caching cached The corresponding transaction results of read buffer that initial transaction caches finally are incorporated into block caching and corresponded to by the corresponding transaction results of write buffer Read buffer in, the corresponding transaction results of write buffer that initial transaction caches are incorporated into block and are cached in corresponding write buffer.

Step 208, it executes corresponding intelligent contract method parallel in each initial transaction caching, obtains each to be processed Corresponding more New Transaction of trading caches.

Specifically, after having created piece caching and the corresponding initial transaction caching of each transaction to be processed, due to initial Transaction caching is the Transaction Information generated during executing intelligent contract method for recording transaction to be processed, therefore each Corresponding intelligent contract method is executed in a corresponding initial transaction caching to be processed of trading, to obtain each transaction to be processed Corresponding more New Transaction caching.That is, intelligent contract is a set of promise defined in digital form, each friendship to be processed is being got After easily corresponding intelligent contract method, each transaction to be processed is needed to be held according to the agreement of corresponding intelligent contract method defined Row, therefore the corresponding transaction results of each transaction to be processed are obtained, update initial transaction caching according to transaction results, i.e., it will transaction As a result it saves into more New Transaction caching.Here transaction results are that each transaction to be processed executes in corresponding transaction caching Corresponding intelligence contract method, the brought change result of intelligent contract method all can be used as corresponding transaction results.

Wherein, it is parallel that each transaction to be processed executes corresponding intelligent contract method in corresponding initial transaction caching It executes, i.e., regardless of the trading order of each transaction to be processed, each transaction to be processed is directly slow in corresponding initial transaction parallel Deposit the corresponding intelligent contract method of middle execution.

Step 210, each more New Transaction caching is successively incorporated into block caching by trading order.

Wherein, sequence has been sequenced when transaction to be processed is bundled to object block, has been not required to sort again herein, can directly acquire each Corresponding trading order to be processed of trading.And when transaction to be processed is not packed into object block, it can be according to each transaction to be processed The exchange hour of time determines trading order, and exchange hour here refers to the corresponding exchange hour point of each transaction to be processed. And trading order refers to the transaction order between each transaction to be processed, it can be according to each corresponding exchange hour to be processed of trading Determine the corresponding trading order of each transaction to be processed.Specifically, each transaction to be processed can be directly acquired according to transaction request Corresponding trading order.

Further, successively that each transaction to be processed is corresponding more according to each corresponding trading order to be processed of trading New Transaction caching is incorporated into block caching, that is, includes the corresponding transaction of institute's transaction to be handled after the completion of merging, in block caching As a result, that is to say, that include each corresponding transaction results to be processed of trading in more New Transaction caching in block caching.

In one embodiment, block caching includes corresponding read and write cache, and each transaction to be processed is corresponding just The transaction caching that begins includes read and write cache, each transaction to be processed corresponding initial transaction cache corresponding read buffer and Write buffer executes corresponding intelligent contract method respectively, respectively obtains the corresponding transaction results of read buffer of initial transaction caching, Transaction results corresponding with the write buffer of initial transaction caching update initial transaction caching further according to transaction results, are updated Transaction caching.

Finally, the trading order between each transaction to be processed is obtained, according to trading order successively by each friendship to be processed The corresponding transaction results of read buffer of easily corresponding initial transaction caching are incorporated into block and cache in corresponding read buffer, will initially hand over The corresponding transaction results of the write buffer easily cached are incorporated into block and cache in corresponding write buffer, i.e., successively will be each according to trading order A corresponding more New Transaction caching to be processed of trading is incorporated into block caching.

Step 212, when current more New Transaction caching to be combined has merged the data cached nothing of transaction with the history in block caching When resource contention, current more New Transaction caching to be combined is incorporated into block caching.

Wherein, each corresponding more New Transaction caching to be processed of trading successively is being incorporated by block caching according to trading order Merging process in, it is understood that there may be the resource contention between intelligent contract method, so-called resource contention are exactly currently pending friendship Easily in block caching to have merged transaction data cached there are competitive relation, only currently pending transaction in block caching When merging the data cached uncontested relationship of transaction, then current more New Transaction caching to be combined is incorporated into block caching.

Wherein, more New Transaction caching to be combined temporarily saves the corresponding current transaction results of currently pending transaction, and Currently pending transaction refers to the transaction to be processed being presently processing, and obtains the corresponding current transaction knot of currently pending transaction More New Transaction to be combined caching where fruit, specifically can be by currently pending transaction corresponding more New Transaction caching as to Merge more New Transaction caching, since each corresponding more New Transaction caching to be processed of trading temporarily saves corresponding transaction knot Fruit, i.e., more New Transaction caching is incorporated into block caching is exactly that each corresponding transaction results to be processed of trading are incorporated into block to delay In depositing, the transaction to be processed that transaction results are incorporated into block caching is successfully updated to processed transaction, i.e., is temporarily protected in block caching Deposited the All Activity of processed transaction as a result, i.e. history merged transaction it is data cached.Here processed transaction refer to The corresponding more New Transaction of processing transaction caches the transaction of the processing after being successfully incorporated into block buffer update, i.e., will successfully correspond to More New Transaction caching be incorporated into block caching processing transaction.

Specifically, the corresponding current more New Transaction caching of currently pending transaction is obtained, will currently more New Transaction caching be made It for more New Transaction to be combined caching, then obtains the history that temporarily saves in block caching to have merged transaction data cached, when to be combined When more New Transaction caching has merged transaction data cached No Assets with history in block caching and conflict, by currently more New Transaction to be combined Caching is incorporated into block caching, i.e., in merging process, the currently pending corresponding intelligent contract method of transaction and processed friendship There is conflict between easily corresponding intelligent contract method, i.e., there are resource contention passes with processed transaction for currently pending transaction System.

Conversely, when trading that data cached there are resource punchings when more New Transaction to be combined caching has merged with history in block caching When prominent, it is determined that between the corresponding intelligent contract method of currently pending transaction intelligence contract method corresponding with processed transaction There are resource contention, current updates caching to be combined can not be incorporated into block caching, need to cache based on block and re-create pair The intermediate transaction caching answered, in centre, transaction caching executes the corresponding intelligence contract method of current more New Transaction caching to be combined, The corresponding transaction caching of implementing result is incorporated into block caching, until each corresponding more New Transaction caching to be processed of trading merges Object block caching is obtained into block caching.

Step 214, when current more New Transaction caching to be combined has merged data cached deposit of trading with the history in block caching In resource contention, then corresponding intermediate transaction caching is re-created based on block caching, centre trade caching execute currently to Merge the corresponding intelligent contract method of more New Transaction caching, the corresponding transaction caching of implementing result is incorporated into block caching.

Step 216, object block is obtained until each corresponding more New Transaction caching to be processed of trading is incorporated into block caching Caching.

Step 218, it is cached to generate according to object block and updates block.

Specifically, when current more New Transaction caching to be combined has merged the data cached presence of transaction with the history in block caching When resource contention, illustrate the corresponding intelligent contract method of currently pending transaction intelligence corresponding with the processed transaction in block caching There are competitive relations for energy contract method, therefore current update friendship to be combined can not be incorporated into block caching at present.In order to solve This problem needs to be based on block caching and re-creates corresponding intermediate transaction caching, executes in intermediate caching of trading current to be combined The corresponding transaction caching of implementing result is incorporated into block caching by the corresponding intelligent contract method of more New Transaction caching.

But cached if re-creating corresponding intermediate trade based on block caching, caching execution is traded currently in centre More New Transaction to be combined caches the implementing result that corresponding intelligent contract method obtains and has still merged transaction caching number with history According to there are competitive relations, corresponding intermediate transaction caching can be re-created based on block caching again again, in centre transaction caching The corresponding intelligent contract method of current more New Transaction caching to be combined is executed, until implementing result has merged transaction caching with history Resource contention is not present in data, then the corresponding transaction caching of implementing result is incorporated into block caching.Wherein it is possible to according to reality Using setting preset times, when reaching preset times, implementing result still can not merge data cached deposit of trading with history In resource contention, then currently pending transaction can be abandoned.

Further, successively that each transaction to be processed is corresponding according to each corresponding trading order to be processed of trading More New Transaction caching is incorporated into block caching, in merging process, if currently pending transaction has merged with history in block caching Transaction caching then re-creates corresponding intermediate transaction caching based on block caching, in centre transaction caching there are when resource contention The corresponding intelligent contract method of current more New Transaction caching to be combined is executed, until currently pending transaction and history in block caching Having merged transaction caching, there is no resource contentions, and the corresponding transaction caching of implementing result is incorporated into block caching.By this method, will In each object block caching that corresponding more New Transaction caching is all incorporated into block caching to be processed of trading, that is to say, that target It is data cached all there is no competitive relation and No Assets conflict that all history in block caching have merged transaction.

Finally, saving a complete block chain in server, block chain includes at least one block, is obtaining target After block caching, need to cache generation update block according to object block.

At least one transaction to be processed is obtained corresponding intelligence by transaction request and closed by above-mentioned contract data process method About method by corresponding piece of object block caching of creation, then creates initial transaction caching corresponding with each transaction to be processed, In Corresponding intelligent contract method is executed in each initial transaction caching parallel, obtains the corresponding more New Transaction of each transaction to be processed Each more New Transaction caching is successively incorporated into block caching by trading order by caching, when current more New Transaction caching to be combined with When history in block caching has merged transaction data cached No Assets conflict, current more New Transaction caching to be combined is incorporated into block In caching, trade that data cached there are resource contentions when current more New Transaction caching to be combined has merged with the history in block caching When, then corresponding intermediate trade is re-created based on block caching and cached, trading in centre, currently update to be combined is handed over for caching execution Corresponding intelligent contract method is easily cached, the corresponding transaction caching of implementing result is incorporated into block caching, until each to be processed Corresponding more New Transaction caching of trading, which is incorporated into block caching, obtains object block caching, caches generation according to object block and updates block.

In one embodiment, corresponding piece of object block caching is created, is created corresponding with each transaction to be processed initial Transaction caching, comprising: obtain object block, be that object block creates corresponding piece of read buffer and block write buffer, base based on contract caching In block read buffer and block write buffer be the corresponding initial transaction read buffer of each transaction creation to be processed and initial transaction write buffer.

Wherein, contract caching refers to for saving the corresponding intelligent contract method of each transaction to be processed, each wait locate After obtaining corresponding intelligent contract method in database, it is slow that the intelligent contract method that will acquire uniformly is put into contract for reason transaction Deposit preservation.And block caching is the corresponding transaction results of transaction to be handled for caching, and initial transaction cache be for It caches each transaction to be processed and executes the Transaction Information that corresponding intelligent contract method generates.Each transaction to be processed is in execution pair When the intelligent contract method answered, change brought by intelligent contract method can all be cached into corresponding initial transaction caching, from And more New Transaction caching is obtained, and each transaction to be processed executes the transaction results that corresponding intelligent contract method generates and can all close And into block caching.That is, temporarily saving the corresponding transaction results of institute's transaction to be handled in block caching.

It specifically, is that newest block creation block caches corresponding piece of read buffer and block write buffer, then base based on contract caching It is that the corresponding initial transaction of the corresponding initial transaction caching of each transaction creation to be processed is read to delay in block read buffer and block write buffer It deposits and initial transaction write buffer.Wherein, transaction to be processed corresponding initial transaction cache corresponding initial transaction read buffer and Initial transaction write buffer executes corresponding intelligent contract method respectively, respectively obtains the initial transaction read buffer of initial transaction caching The corresponding transaction results of initial transaction write buffer of corresponding transaction results and initial transaction caching are read slow according to initial transaction It deposits corresponding transaction results and updates initial transaction read buffer, obtain more New Transaction read buffer, similarly write according to initial transaction slow It deposits corresponding transaction results update initial transaction write buffer and obtains more New Transaction write buffer.

Finally, the corresponding transaction results of more New Transaction read buffer that more New Transaction caches, which are incorporated into block, caches corresponding piece In read buffer, by more New Transaction cache the corresponding transaction results of more New Transaction write buffer be incorporated into block cache corresponding piece write it is slow In depositing.

In one embodiment, as shown in figure 3, Fig. 3 is shown, block in one embodiment is cached and what initial transaction cached shows It is intended to, specifically can be, server obtains newest block, is that newest block creation block caches corresponding piece of reading based on contract caching It include block read buffer and block write buffer in caching and block write buffer, i.e. block caching.Further, it is write based on block read buffer and block slow The corresponding initial transaction read buffer of each transaction creation to be processed and initial transaction write buffer are saved as, i.e., each transaction to be processed is deposited In corresponding initial transaction read buffer and initial transaction write buffer.

In one embodiment, as shown in figure 4, executing corresponding intelligent contract side parallel in each initial transaction caching Method obtains the corresponding more New Transaction caching of each transaction to be processed, comprising:

Step 402, corresponding intelligent contract is executed parallel in each corresponding initial transaction read buffer to be processed of trading Method obtains the corresponding more New Transaction read buffer of each transaction to be processed.

Step 404, corresponding intelligent contract is executed parallel in each corresponding initial transaction write buffer to be processed of trading Method obtains the corresponding more New Transaction write buffer of each transaction to be processed.

Wherein, the corresponding more New Transaction caching of each transaction to be processed is write slow including more New Transaction read buffer and more New Transaction Deposit, more New Transaction read buffer is the read access situation for recording transaction to be processed, more New Transaction write buffer be for record to The write access situation of transaction is handled, each transaction to be processed can execute corresponding intelligent contract method in initial transaction caching, To obtain more New Transaction caching.

Specifically, corresponding intelligent contract method is executed parallel in each corresponding transaction read buffer to be processed of trading, Intelligent contract method all saves in the easy read buffer of best friend brought variation, obtains the corresponding transaction of each transaction to be processed Read buffer is as a result, saving transaction read buffer result to more New Transaction read buffer.Similarly, corresponding in each transaction to be processed Corresponding intelligent contract method is executed in transaction write buffer parallel, obtains the corresponding transaction write buffer knot of each transaction to be processed Fruit saves transaction write buffer result into more New Transaction write buffer.That is, transaction read buffer and transaction write buffer are all used to execute Corresponding execution contract, temporarily saves corresponding implementing result.

In one embodiment, delay as shown in figure 5, each more New Transaction caching is successively incorporated into block by trading order It deposits, comprising:

Step 502, the corresponding trading order of each transaction to be processed is obtained.

Wherein, sequence has been sequenced when transaction to be processed is bundled to object block, has been not required to sort again herein, can directly acquire each Corresponding trading order to be processed of trading.And when transaction to be processed is not packed into object block, it can be according to each transaction to be processed The exchange hour of time determines trading order, and exchange hour here refers to the corresponding exchange hour point of each transaction to be processed. Specifically, server (node) directly acquires the corresponding trading order of each transaction to be processed.

Step 504, each corresponding more New Transaction write buffer to be processed of trading successively is incorporated by block according to trading order In write buffer.

Specifically, after obtaining the corresponding trading order of each transaction to be processed, successively each transaction to be processed is corresponded to More New Transaction write buffer be incorporated into block write buffer.That is, by the transaction write buffer result for write buffer of trading be committed to block write it is slow In depositing, i.e., block write buffer for it is to be handled transaction it is corresponding transaction write buffer result union.

Wherein, the corresponding intelligence of each transaction to be processed is identified by the way that more New Transaction write buffer is committed to block write buffer With the presence or absence of conflict between contract method, it can be specifically explained by following embodiment, not make any repeat herein.

Wherein, and the corresponding intelligent contract method of each transaction to be processed in the process of implementation, can will from database or In the data deposit block read buffer read in contract caching.

In one embodiment, as shown in Figure 5A, Fig. 5 A shows the transaction knot in one embodiment in more New Transaction caching Fruit is incorporated into the schematic diagram of block caching.Fig. 5 A show transaction 1 read buffer, transaction 1 write buffer and transaction 2 read buffers, transaction 2 write it is slow It deposits.Specifically, according to trading order, 1 read buffer of transaction is committed in block read buffer, 1 write buffer of transaction is committed to block and is write In caching.And then 2 read buffers of transaction are committed in block read buffer, 2 write buffers of transaction are committed in block write buffer.

In one embodiment, as shown in fig. 6, current more New Transaction caching to be combined for current more New Transaction write buffer or Current more New Transaction read buffer, initial transaction caching include initial transaction read buffer and initial transaction write buffer, and current update is handed over Easy write buffer is that currently pending transaction executes corresponding intelligent contract method in current initial transaction write buffer and obtains, when Preceding more New Transaction read buffer is that currently pending transaction executes corresponding intelligent contract method in current initial transaction read buffer It obtains, block caching includes block read buffer and block write buffer, when current more New Transaction caching to be combined and the history in block caching Having merged transaction, data cached there are when resource contention, comprising:

Step 602, when more New Transaction to be combined caching is current more New Transaction write buffer, going through in block write buffer is obtained History has merged that transaction is data cached, and it is the corresponding more New Transaction write buffer of processed transaction that it is data cached, which to have merged transaction, for history, Corresponding more New Transaction caching to be processed of trading is updated to processed transaction after being incorporated into block caching.

Wherein, more New Transaction to be combined caching can for current transaction write buffer result or current transaction read buffer as a result, More New Transaction caching includes more New Transaction read buffer and more New Transaction write buffer, and current write buffer of trading is the result is that currently pending Transaction executes what corresponding intelligent contract method obtained in currently more New Transaction write buffer, current read buffer of trading be currently to Processing transaction executes what corresponding intelligent contract method obtained in currently more New Transaction read buffer, and block caching includes block read buffer With block write buffer, each corresponding more New Transaction read buffer to be processed of trading is incorporated into block read buffer, each transaction to be processed Corresponding transaction write buffer is incorporated into block write buffer.

Wherein, more New Transaction caching to be combined can be current more New Transaction write buffer here, can also update to be current Transaction read buffer.Specifically, it is current more New Transaction write buffer when more New Transaction to be combined caches, illustrates currently pending friendship Yi Geng New Transaction write buffer execute current more New Transaction write buffer that corresponding intelligent contract method obtains as it is to be combined more New Transaction caching.Obtain block write buffer in history merged transaction it is data cached, history merged transaction it is data cached be The corresponding more New Transaction write buffer of processing transaction, corresponding more New Transaction caching to be processed of trading are updated to after being incorporated into block caching Processed transaction.

Wherein, processed transaction refers to that corresponding more New Transaction caching is successfully incorporated into block buffer update by be processed trade Processing transaction later.History in block caching, which has merged, is not present punching between the data cached corresponding transaction to be processed of transaction It is prominent.That is, transaction write buffer result will not be committed in block write buffer if transaction to be processed has conflict, therefore block is write Any conflict is all not present between processed transaction in caching.

Step 604, having merged transaction at least one history when current more New Transaction write buffer, data cached there are intersections When, it is determined that current more New Transaction caching to be combined has merged with the history in block caching trades that data cached there are resource punchings It is prominent.

Specifically, having merged transaction at least one history when current more New Transaction write buffer, data cached there are intersections When, illustrate that same holding tank has all been changed in currently pending transaction and processed transaction, so holding in practical intelligent contract method During row, currently pending transaction has to wait for start after the completion of the corresponding transaction of all processed transaction, i.e., currently Transaction to be processed cannot be parallel with processed transaction, it is determined that the corresponding intelligent contract method of currently pending transaction with it is processed There is conflict in corresponding intelligent contract method of trading.

In one embodiment, as shown in Figure 6A, Fig. 6 A shows intelligent contract method collision detection in one embodiment Schematic diagram.Fig. 6 A shows block write buffer and the corresponding current transaction write buffer of currently pending transaction as a result, currently pending friendship It is easily transaction 4, includes transaction 1, transaction 2,3 corresponding transaction write buffers of transaction in block write buffer as a result, in blocking write buffer Historical trading write buffer results set.As shown in Figure 6A, the corresponding current transaction write buffer result of currently pending transaction and There are intersections at least one historical trading write buffer result in block write buffer, it is determined that currently pending corresponding intelligence of trading There is conflict in contract method intelligent contract method corresponding with processed transaction, i.e., currently pending transaction have to wait for it is all Processing is traded, and transaction could start after the completion for corresponding transaction.

In one embodiment, as shown in fig. 7, currently more New Transaction write buffer at least one history transaction ought have been merged It is data cached that there are when intersection, comprising:

Step 702, it obtains the corresponding current transaction of current more New Transaction write buffer and writes key-value pair, key-value pair is write in current transaction Including current key and corresponding current value.

Step 704, it obtains history and has merged the data cached corresponding historical trading of transaction and write key-value pair, historical trading writes key Value is to including history button and corresponding history value.

Wherein, currently more New Transaction write buffer temporarily saves current transaction write buffer as a result, transaction write buffer result can To be key-value pair, so-called key-value pair (" key=value ") character string is commonly used in exploitation, corresponds to phase behind each key The value answered will export corresponding result when pressing corresponding key.Therefore, the more corresponding key of New Transaction write buffer can be passed through Value whether there is conflict between the intelligent contract method of detection.

Specifically, it obtains the corresponding current transaction of the current transaction write buffer result in current more New Transaction write buffer and writes key Value pair, it includes current key and corresponding current value that key-value pair is write in current transaction, while obtaining history to have merged transaction data cached Corresponding historical trading writes key-value pair, and it includes history button and corresponding history value that historical trading, which writes key-value pair,.

Step 706, when there are when at least one target histories key identical with current key in each history button, it is determined that when Preceding more New Transaction write buffer has merged transaction at least one history, and data cached there are intersections.

Specifically, target histories key identical with current key is obtained from each history button, when current key is corresponding current When being worth target histories value difference corresponding with target histories key, it is same to illustrate that currently pending transaction and processed transaction have all been changed One holding tank, so currently pending transaction has to wait for all processed friendships in practical intelligent contract method implementation procedure It could start after the completion of easy corresponding transaction, i.e., currently pending transaction cannot be parallel with processed transaction, it is determined that currently more New Transaction write buffer has merged transaction at least one history, and data cached there are intersections.

It in one embodiment, as shown in Figure 6A, include the corresponding history of processed transaction in the block write buffer in Fig. 6 A Write buffer of trading as a result, as transaction 1 transaction write buffer result: 1=1, the 1 of left side of the equal sign represent key key, the 1 of right side of the equal sign Typical value value, trade 2 transaction write buffer result: 2=2 and trade 3 transaction write buffer result 3=3, currently wait locate Reason transaction is 4 corresponding transaction write buffer results of transaction: 3=4,4=4, thus, it could be seen that in the transaction write buffer result of transaction 4 Key be 3 with block caching in historical trading write buffer result in key be 3 value it is not identical, it is determined that currently pending transaction Exist with the processed transaction of front and conflict, needs to wait all processed corresponding transaction of trading of fronts can just open after the completion Begin.

In one embodiment, as shown in figure 8, on the basis of Fig. 6, when current more New Transaction caching to be combined and block are slow History in depositing has merged transaction, and data cached there are when resource contention, comprising:

Step 802, the corresponding current more New Transaction read buffer of currently pending transaction is obtained, currently more New Transaction will read to delay It deposits and is cached as more New Transaction to be combined.

Step 804, having merged transaction at least one history when current more New Transaction read buffer, data cached there are intersections When, it is determined that current more New Transaction caching to be combined has merged with the history in block caching trades that data cached there are resource punchings It is prominent.

It wherein, currently include that currently pending transaction is held in corresponding more New Transaction read buffer in more New Transaction read buffer The corresponding intelligent contract method of row obtains, and it is that all processed transaction are corresponding in block caching that it is data cached, which to have merged transaction, for history More New Transaction write buffer is as a result, more New Transaction write buffer result refers to processed transaction in corresponding more New Transaction write buffer here Execute what corresponding intelligent contract obtained.

Wherein, processed transaction refers to that corresponding more New Transaction caching is successfully incorporated into block buffer update by be processed trade Processing transaction later.History in block caching, which has merged, is not present punching between the data cached corresponding transaction to be processed of transaction It is prominent.That is, transaction write buffer result will not be committed in block write buffer if transaction to be processed has conflict, therefore block is write Any conflict is all not present between forward direction in caching is to be processed.

Specifically, the corresponding current more New Transaction read buffer of currently pending transaction is obtained, currently more New Transaction read buffer In include that currently pending transaction executes what corresponding intelligent contract method obtained in corresponding more New Transaction read buffer, will be current More New Transaction read buffer is cached as more New Transaction to be combined, when current more New Transaction read buffer has merged at least one history Trading, data cached there are when intersection, it is determined that the corresponding intelligent contract method of currently pending transaction is corresponding with processed transaction Intelligent contract method exist conflict.

In one embodiment, as shown in figure 9, currently more New Transaction read buffer at least one history transaction ought have been merged It is data cached that there are when intersection, comprising:

Step 902, it obtains the corresponding current transaction of current more New Transaction read buffer and reads key-value pair, key-value pair is read in current transaction Including current key and corresponding current value.

Step 904, it obtains history and has merged the data cached corresponding historical trading of transaction and write key-value pair, historical trading writes key Value is to including history button and corresponding history value.

Wherein, currently more New Transaction read buffer temporarily saves current transaction read buffer as a result, transaction read buffer result can To be key-value pair, key-value pair (" key=value ") character string here is commonly used in exploitation, corresponds to behind each key Corresponding value, when pressing corresponding key, will export corresponding result.It therefore, can be corresponding by more New Transaction read buffer Key-value pair detects between intelligent contract method with the presence or absence of conflict.

Specifically, it obtains the corresponding current transaction of the current transaction read buffer result in current more New Transaction read buffer and reads key Value pair, it includes current key and corresponding current value that key-value pair is read in current transaction, while obtaining history to have merged transaction data cached Corresponding historical trading writes key-value pair, and it includes history button and corresponding history value that historical trading, which writes key-value pair,.

Step 906, when there are when at least one target histories key identical with current key in each history button, it is determined that when Preceding more New Transaction read buffer has merged transaction at least one history, and data cached there are intersections.

Specifically, when, there are when at least one target histories key identical with current key, illustrating each in each history button For the corresponding intelligent contract method of a transaction to be processed in parallel situation, the value of the target histories key in different server has can Different situations can be had, it is unified pessimistically to think currently pending transaction in order to keep the consistency between each server Having read legacy data, i.e., currently pending transaction has to wait for start after the completion of the corresponding transaction of all processed transaction, So currently pending transaction cannot be parallel with processed transaction, it is determined that current more New Transaction read buffer and at least one history Having merged transaction, data cached there are intersections.

It in one embodiment, as shown in Figure 9 A, include the corresponding history of processed transaction in the block write buffer in Fig. 9 A Write buffer of trading as a result, as transaction 1 transaction write buffer result: 1=1, the 1 of left side of the equal sign represent key key, the 1 of right side of the equal sign Typical value value, trade 2 transaction write buffer result: 2=2 and trade 3 transaction write buffer result 3=3, currently wait locate Reason transaction 3 corresponding transaction read buffer results: 3=0,4=4, thus, it could be seen that transaction 4 transaction read buffer result in the presence of with The identical target histories key of history button in block caching, i.e. key=3, therefore regardless of whether the corresponding value of key=3 identical, all may be used It determines that currently pending transaction exists with the processed transaction of front to conflict, needs to wait all processed transaction of fronts corresponding It could start after the completion of transaction.
