A kind of data structure of the block chain as storing data in chronological order, can support different common recognition mechanism.Common recognition mechanism is area The significant components of block chain technology.The target of block chain common recognition mechanism is that all honest nodes is made to save consistent block chain view Figure, while meeting two attributes: the prefix part of consistency, the block chain that all honesty nodes save is identical；Validity, By the information of certain honest node publication at last by other all honest nodes records in the block chain of oneself.

Source chain, object chain: source chain is the block chain where across chain data processing request initiator.Object chain is across chain data Handle the block chain where the recipient of request.In an alternative embodiment, linking sources, which are received, is based on being somebody's turn to do across chain transaction system In across the chain transaction request that issues of source account, then needing will should transaction money in across chain transaction request in corresponding Transaction Information Production is transferred to the target account to object chain from source account.

Intelligent contract: i.e. Smart contract is a set of agreement for defining in digital form, propagating, verify or executing, The agreement of these agreements can be executed above including contract participant.Intelligent contract allow in no third-party situation into Transaction that row is credible, these transaction are traceable and irreversible.

Across chain: carrying out data communication between different block chains, realize the value interconnection in the block chain world.

Mei Keer tree: also known as Hash tree, a binary tree of cryptographic Hash is stored, by a root node, one group of intermediate node It is formed with one group of leaf node.Nethermost leaf node includes cryptographic Hash, and each intermediate node is its two child nodes The cryptographic Hash of content, root node are also to be made of the cryptographic Hash of its two sub- node contents.Meter can efficiently be verified very much The storage, processing and transmission of any data, are able to confirm that the data received are not destroyed or distort between calculation machine.

In the embodiment of the present application, the first block chain corresponds to source chain, and the second block chain corresponds to object chain, each block chain It is made of multiple nodes, each node can be receiving node, perhaps handle node or common recognition node etc..The application is implemented Only function declaration and the citings such as receiving node, processing node, common recognition node in example, without limitation.Any in block chain Node may be receiving node, processing node or common recognition node, and, it be receiving node there is also same node is again processing Node perhaps another node be handle node again be common recognition node or another node be receiving node, handle node and The various possibility of common recognition node etc..First block chain, the second block chain are only intended to distinguish the angle that different blocks chain is played the part of Color；First block chain refers to a kind of block chain that can be used as source chain, and the second block chain refers to can be used as the one of object chain Class block chain, and being not specific to a certain block chain is " the first block chain " or " the second block chain ".That is, across chain data processing Either block chain in system can be used as source chain, and the block chain as source chain can be described as the first block chain；Similarly, same system Either block chain in system also can be used as object chain, and the block chain as object chain can be described as the second block chain.

Referring to FIG. 1, it illustrates the system architecture diagram across chain data processing system that the application one embodiment provides, It should include first terminal 11, the first data processing server 12, the first block chain, second terminal in across chain data processing system 14, the second data processing server 15 and the second block chain.In embodiment shown in Fig. 1, the first data processing server 12 and second data processing server 15 can be a server, be also possible to several servers composition server cluster Or cloud computing center.First block chain supports have in the first block chain including at least one by multiple block chain servers 13 The server of across chain intelligence contract function supports that the server of across chain intelligence contract function can be multiple block chain servers 13 In one or more.Second block chain is supported by multiple block chain servers 16, includes at least one tool in the second block chain There is the server of across chain intelligence contract function, supports that the server of across chain intelligence contract function can be multiple block chain servers One or more in 16.Public block chain such as ether mill, super in block chain network with across chain intelligence contract function Account book Hyperledger, RSK etc..

First terminal 11 and second terminal 14 can be the electronic equipment for having Internet communication capacity, and only example goes out two in figure A terminal, in fact, passing through the terminal of network connection to the first data processing server 12 or the second data processing server 15 Equipment has very much, and terminal device, which can be mobile phone, tablet computer either dedicated handheld device etc., has wireless communication function Electronic equipment, be also possible to the access in radio such as personal computer (personal computer, abbreviation PC), laptop The equipment that mode connects online.

First data processing server 12 can be communicated with first terminal 11, the first block chain by network, network It can be any one in the communication networks such as local area network, wide area network or mobile Internet.Installation is by first in first terminal 11 The client that data processing server 12 is supported.Client of the first terminal 11 based on installation and the first data processing server 12 It is communicated.

Second data processing server 15 can be communicated with second terminal 14, the second block chain by network, network It can be any one in the communication networks such as local area network, wide area network or mobile Internet.Installation is by second in second terminal 14 The client that data processing server 15 is supported.Client of the second terminal 14 based on installation and the second data processing server 15 It is communicated.

In this scenario, first terminal 11 can be used as the publisher across chain transaction, by the client of its installation to the Across chain transaction request is sent in one data processing server 12.First data processing server 12 should across chain transaction request upload To the first block chain.Second terminal 14 can be used as the target side across chain transaction, receive the second number by the client of its installation The processing result across chain transaction request sent according to processing server 15.Certainly, first terminal 11 may be to trade across chain Target side receives the processing result across chain transaction request, second terminal 14 or the publisher across chain transaction request, initiates Across chain transaction.

It should be noted that application scenarios mentioned above are merely for convenience of understanding spirit herein and principle and showing Out, the embodiment of the present application is unrestricted in this regard.On the contrary, the embodiment of the present application can be applied to applicable any field Scape.

In order to make it easy to understand, using the first block chain as source chain in specification, the second block chain is said as object chain It is bright.

In the prior art, across chain transaction is generally synchronization process.Specifically, source chain is by across chain transaction at the part of source chain After the completion of reason, across chain transaction request is sent to object chain.Object linking receives across chain transaction request, executes across the chain transaction of completion and exists Behind the part of object chain, processing result is charged to the account book of object chain, and send across chain trading processing result to source chain.Linking sources After receiving across chain trading processing result, total processing result is kept accounts, thus across the chain transaction that finishes.Wherein, in the second block chain The first block chain needs to wait always during handling across chain transaction, cannot handle other transaction.And the second block chain is to After one block chain sends across chain trading processing result, it is also desirable to which the reply for waiting the first block chain, can just finish across chain transaction.This There is resource and time waste in across the chain transaction synchronization process mode of kind.

The application is based on block chain technology, and it is asynchronous place that the first block chain and the second block chain, which handle the process traded across chain, Reason.After first block chain obtains transaction implementing result, transaction implementing result is written in the first account book, is rather than directly to second Block chain is sent.In this way, the first block chain is fed back without waiting for the processing of the second block chain, other transaction can be continued with, To save the waiting time of the first block chain, treatment effeciency is improved.And second block chain without handing at once across chain It is easily handled, the processing pressure of the second block chain can be balanced with processing time of the flexible arrangement each across chain transaction.Together Reason, the second block chain is executed trades to obtain transaction implementing result across chain after, transaction implementing result is charged in the second account book, by the One block chain monitors the second account book, determines in suitable the second operating result of time-triggered protocol, so as to be selected by the first block chain Processing opportunity is selected, more flexibly, and the process performance of data under across chain scene is improved, saves the time.

To solve the above-mentioned problems, below with reference to application scenarios shown in FIG. 1, area is based on to provided by the embodiments of the present application Across the chain data processing method of block chain is illustrated.

Referring to FIG. 2, the embodiment of the present application provides a kind of across chain data processing method based on block chain, such as Fig. 2 institute Show, method includes:

Step the S201: the first block chain determines data processing content according to across the chain data processing request received.

Wherein, first comprising the first across chain intelligence contract being deployed in the first block chain in data processing content calls Second call address of address and the second across chain intelligence contract being deployed in the second block chain, the first across chain intelligence contract with Second across chain intelligence contract is corresponding.First across chain intelligence contract is deployed in the first block chain, the second across chain intelligence contract portion It is deployed in the second block chain.

The deployment of intelligent contract can be understood as the contract that will be appointed and approve that deployment exists through the common recognition of block chain network In block chain；The operation of intelligent contract can be understood as executing contract automatically when checking and meeting contract execution condition and will transport Row result is recorded in block chain.In simple terms, intelligent contract is exactly the digitized version of traditional contract.They are in block chain The computer program run on database, when condition that can be written in meeting its source code, voluntarily execute.Intelligence and about one Denier, which writes, to be trusted by user, and agreement terms cannot be changed.Specifically, before executing across chain data processing, It can state to have developed in across chain intelligence contract with across the chain intelligence contract of joint consultation between first block chain and the second block chain At across chain intelligence contract program (such as the program code that can be some functional dependences called).Then in the first block The first across chain intelligence contract is issued in chain, and common recognition processing is carried out by the node device in the first block chain；It, can after common recognition passes through The first across chain intelligence contract is included the distributed data base stored to the first block chain, to complete the portion of the first intelligent contract Administration.Meanwhile the second across chain intelligence contract is issued in the second block chain, common recognition is carried out by the node device in the second block chain Reason；After common recognition passes through, the second across chain intelligence contract can be included into the distributed data base stored to the second block chain, with complete At the deployment of the second across chain intelligence contract.

It should be noted that pertaining only to two block chains in the embodiment of the present application, but across the chain number in the embodiment of the present application Across the chain data processing system of multiple block chains is also applied for according to processing method.There is the case where multiple block chains in systems Under, it can hold consultation for all block chains, and a across chain intelligence contract is disposed on each block chain, so that system In any block chain between can be performed across chain transaction.

In specific implementation process, receiving node in the first block chain receive across chain transaction request after, to the request It is parsed, determines transaction content.The first across chain intelligence that application layer in transaction content comprising the first block chain is disposed is closed The application layer station address of the first call address, the first block chain about, the second block chain ID, corresponding on the second block chain The second call address and operating method and operation input parameter of two across chain intelligence contracts.

It should be noted that the receiving node, processing node, common recognition node etc. in the embodiment of the present application are only function declaration And citing, without limitation.Any node in block chain may be receiving node, handle node or common recognition node, and, also deposit Same node be receiving node not only be processing node perhaps another node be handle node again be know together node or Another node is the various possibility of receiving node, processing node and node etc. of knowing together.

Step the S202: the first block chain calls the first across chain intelligence contract according to the first call address, executes data processing The first operation corresponding with the first block chain, obtains the first operating result in content.

In specific implementation process, for the processing node of the first block chain according to the first call address, calling is deployed in the firstth area The first across chain intelligence contract on block chain executes the first operation corresponding with the first block chain in operating method.Operating method can For example to transfer accounts, withhold, operation input parameter such as transfer amounts, deducted amount etc..Handle node by first operation and Operation input parameter inputs in the first across chain intelligence contract, and the first across chain intelligence contract executes transaction, and the first transaction of output executes As a result, across a chain transaction ID is distributed simultaneously, the secondth area in the above-mentioned first transaction implementing result of binding, data processing content Block chain ID, the second call address on the second block chain, operating method and operation input parameter etc., and above-mentioned transaction is executed into shape State and content are cached.

After step the S203: the first block chain reaches common understanding to the first operating result, data processing content and first are grasped Make result and the first account book is written.

In specific implementation process, all nodes in the first block chain need to know together to the first transaction implementing result, when After common recognition passes through, node is handled by the first transaction implementing result and the second block chain ID, the second call address, operating method etc. Transaction content is written in the first account book of the first block chain.

Step the S204: the second block chain is known when the first operating result is written in the first account book of the first block chain, from Data processing content is obtained in one account book.

Here, the second block chain knows that the first account book updates, and can actively supervise to the first account book for the second block chain It listens, or the second block chain passively learns that the first account book updates.Second block chain actively monitors the first account book, such as the Two block chains check the state of the first account book according to preset frequency, determine new transaction content whether is added in the first account book. After second block chain passively learns that the first account book updates, such as the first block chain has updated the first account book, sent out to the second block chain One is sent to check request, the second block chain can reply the message acknowledged receipt of, but the secondth area to the first block chain at once Block chain does not check the first account book immediately, but at suitable time point, such as when the second block chain free time or daily regulation Period checks and obtains the transaction content in the first account book.In this way, the second block chain can flexibly control processing transaction when Machine, and the first block chain can continue with other transaction without the processing result for waiting the second block chain.

Step the S205: the second block chain calls the second across chain intelligence contract according to the second call address, executes data processing The second operation corresponding with the second block chain, obtains the second operating result in content.

Specifically, after the second block chain obtains the data processing content in the first account book, the processing section of the second block chain Point calls the second across chain intelligence contract being deployed on the second block chain according to the second call address in data processing content, Execute the second operation corresponding with the second block chain in operating method.Operating method can be such as input fund, operation input Parameter is for example transferred to amount of money etc..Node is handled to input the second operation and operation input parameter in the second across chain intelligence contract, Second across chain intelligence contract executes transaction, output the second transaction implementing result, and above-mentioned second transaction implementing result is delayed It deposits.

After step the S206: the second block chain reaches common understanding to the second operating result, the second account is written into the second operating result This.

In specific implementation process, all nodes in the second block chain need to know together to the second transaction implementing result, when After common recognition passes through, the second transaction implementing result is written in the second account book of the second block chain processing node.Preferably, in order to just In identification, the second transaction implementing result is also bound with across chain transaction ID.

When the second operating result is written in the second account book for knowing the second block chain in step the S207: the first block chain, from Second account book obtains the second operating result.

Similarly, the first block chain knows that the second account book updates, and can actively supervise to the second account book for the first block chain It listens, or the first block chain passively learns that the second account book updates, and is not described herein.

The first account book is written in second operating result by step the S208: the first block chain.

In order to guarantee the consistency of data processed result in the first block chain and the second block chain, the first block chain needs pair Second operating result is detected.That is after above-mentioned steps S207, further includes:

First block chain detects the second operating result；

If the second operating result is consistent with data processing content, the behaviour that the second operating result is written to the first account book is executed Make；

If the second operating result is not consistent with data processing content, rolling back action is executed to the first operating result.

In specific implementation process, there are the second block chains to execute the possibility to fail to the second operation.In this case, The common recognition node of one block chain be can detecte out in the second operating result and data processing by the detection to the second operating result Appearance is not consistent, i.e. the second operating result is different from the implementing result of the first block chain, then it is assumed that the second operation of the second block chain As a result wrong, the first block chain needs to carry out rollback to the first operating result, to guarantee the first block chain and the second block chain Data consistency.

In addition, in order to guarantee legitimacy across chain transaction request and the legitimacy across chain transaction, the first block chain according to Across the chain data processing request received, after determining data processing content, further includes:

First block chain detects the digital signature in across chain data processing request；

First block chain calls first to manage intelligent contract, detects to the legitimacy of data process content；

If detecting successfully, calls the first across chain intelligence contract to execute the first operation, obtain the first operating result；

If detection failure, by data processing content-label failure result.

It specifically, also include the digital signature of the initiator across chain data processing request in across chain data processing request. After first block chain receives across chain data processing request, common recognition node digital signature therein is detected, if detection at Function just carries out subsequent processing, if detection failure, directly should across chain data processing request label failure result, and to across chain The initiator's feeding back unsuccessful result and failure cause of data processing request.

After digital signature detects successfully, the first block chain also calls the intelligent contract of the first management to data process content Legitimacy is tested.Specifically, it can detecte and whether deploy across chain intelligence contract on the first block chain, the first block chain Whether application layer station address is legal, and whether application layer user balance pays across chain tranaction costs etc. enough on the first block chain. In the case where detection passes through, then the first across chain intelligence contract is called to execute the first operation.Any one detection is obstructed if it exists The case where crossing, then should across chain data processing request identify failure result, and to initiator's feeding back unsuccessful across chain request of data And failure cause as a result.

Above-mentioned first, which manages intelligent contract, is also deployed on the first block chain, with the function of the first across chain intelligence contract with And effect is different.First across chain intelligence contract is mainly used for executing across chain transaction, and building mono- Mei Keer tree.First The main function for managing intelligent contract is the legitimacy of inspection data, and whether inspection data is tampered, guarantee the accurate of data and Safety.

It should be noted that the management intelligence contract in the embodiment of the present application is functional restriction.Manage intelligent contract The general designation that can be multiple intelligent contracts, for example, the inspection for digital signature in trading across chain deploys on the first block chain One intelligent contract, the inspection for across chain transaction legitimacy are deployed an intelligent contract, are detected for using Mei Keer tree Whether data, which are tampered, deploys an intelligent contract, then above three contract is referred to as the first management intelligence contract.It is another In possible embodiment, first manage intelligent contract may be the same intelligent contract and meanwhile can to digital signature, across chain Transaction legitimacy and Mei Keer tree are tested.In addition, managing intelligent contract also can have other functions, for example, to across Chain intelligence contract is managed, and the embodiment of the present application is without limitation.

Further, on the one hand in order to prevent across chain transaction be tampered during transmission, on the other hand need to guarantee across Chain transaction will not malfunction in transmission process.In a kind of optional embodiment, block chain is according to the implementing result structure traded across chain Mei Keer tree is built, and is verified using Mei Keer tree.Traditional method is will to trade to be encrypted, and is then passed It is defeated, it is decrypted at receiving node.However since encrypted communication is frequent, trading volume is larger, the management of frequent encryption and decryption and key It is all relative complex, therefore conventional approach cannot be used, and the transaction List Table for the use of both solving transmission of Mei Keer tree is correct The problem of property, and reduce transmission link, to accelerate bulk velocity.By constructing Mei Keer tree, passed carrying out across chain transaction It is subsidiary to transmit Mei Keer tree together in defeated process.In recipient, the root node of Mei Keer tree is only verified.If occurring It distorts, then the root node of Mei Keer tree will change, and the transaction letter distorted can be found by binary chop Breath.

Specifically, step the S202: the first block chain calls the first across chain intelligence contract according to the first call address, executes number According to the first operation corresponding with the first block chain in process content, after obtaining the first operating result, further includes:

First block chain calls the first across chain intelligence contract, is based on data processing content and the first operating result, building Mono- Mei Keer tree；

The first account book is written in the root node of mono- Mei Keer tree by the first block chain.

By taking Mei Keer tree as shown in Figure 3 as an example, specific configuration method is as follows:

The cryptographic Hash of All Activity data is calculated, for example, using the first operating result as data 1, in data processing content Second block chain ID calculates separately the first behaviour as data 4 as data 3, operating method as data 2, the second call address Make the cryptographic Hash of result, the cryptographic Hash of the second block chain ID, the cryptographic Hash of the second call address, the cryptographic Hash of operating method, obtains To 4 nodes of Mei Keer tree, respectively node 1-1, node 1-2, node 1-3 and node 1-4.Wherein, hash () is that will count According to execution Hash operation.Above-mentioned node 1-1, node 1-2, node 1-3 and node 1-4 are the leaf node of Mei Keer tree.According to The secondary cryptographic Hash by two adjacent leaf nodes is merged into a character string, then calculates the cryptographic Hash of this character string, Father node of the acquired cryptographic Hash as two leaf nodes.Such as Fig. 3, node 1-1 and node 1-2 are merged into a character String, calculates the cryptographic Hash of this character string, and as the value of node 2-1, the father that interior joint 2-1 is node 1-1 and node 1-2 is saved Point.It successively constructs upwards, if certain layer of node number is odd number, by the layer, the last one node is replicated, and gathers into idol Aforementioned father node cryptographic Hash calculating process is executed after several nodes.The above process is executed repeatedly, until obtaining a single root Node, the root node of root node Shi Mei Keer tree, entire data structure is Mei Keer tree construction.

First block chain calls the first across chain intelligence contract, constructs mono- Mei Keer tree according to the above method, i.e., will count It is inputted in the first across chain intelligence contract according to the data such as process content and the first operating result, the first across chain intelligence contract is based on upper It states construction method and constructs mono- Mei Keer tree, and export the root node of mono- Mei Keer tree, then by the root of mono- Mei Keer tree Node is written in the first account book.

Later, the second block chain is known in the first account book of the first block chain and is written after the first operating result, further includes:

Second block chain obtains the root node of mono- Mei Keer tree from the first account book；

Second block chain calls second to manage intelligent contract, using the root node of mono- Mei Keer tree to data process content And first operating result detected.

In specific implementation process, the second block chain is after the root node for obtaining mono- Mei Keer tree in the first account book, benefit The data processing content of acquisition and the first operating result are detected with the root node of mono- Mei Keer tree, determined at data Reason content and the first operating result are not tampered with.Specially the second block chain calls second to manage intelligent contract, according to above-mentioned The mode of building Mei Keer tree again pulls up a Mei Keer tree to the data processing content and the first operating result that receive, Then the newly-built root node of Mei Keer tree and the root node of mono- Mei Keer tree are compared.If the two is identical, show Data processing content and the first operating result are not tampered with；If the two is different, show data processing content and the first behaviour Make there are data to be tampered in result, then stop subsequent processing, sends alarm information to the first block chain.

On the other hand, the second block chain also to the second operating result construct Mei Keer tree, thus prevent the first block chain from The data obtained in second block chain are tampered.

Second block chain calls the second across chain intelligence contract according to two call address in data processing content, executes data The second operation corresponding with the second block chain in process content, after obtaining the second operating result, further includes:

Second block chain calls the second across chain intelligence contract, is based on the second operating result, constructs bis- Mei Keer tree；

The second account book is written in the root node of bis- Mei Keer tree by the second block chain.

Specifically, the second block chain executes completion to the second operation, after obtaining the second operating result, based on the second operation As a result, and other information for needing to be synchronized to the first block chain, construct bis- Mei Keer tree, for preventing the second operating result It is tampered.Second block chain calls the second across chain intelligence contract, and the data such as the second operating result and other related datas are defeated Enter in the second across chain intelligence contract, the second across chain intelligence contract is based on above-mentioned construction method and constructs bis- Mei Keer tree, and defeated The root node of bis- Mei Keer tree out, then the root node of bis- Mei Keer tree is written in the second account book.Bis- Mei Keer tree Specific construction method is not described herein referring to the construction method of above-mentioned Mei Keer tree.

It is written after the second operating result in this way, the first block chain is known in the second account book of the second block chain, further includes:

First block chain obtains the root node of bis- Mei Keer tree from the second account book；

First block chain detects the second operating result, comprising:

First block chain calls first to manage intelligent contract using the root node of bis- Mei Keer tree to the second operating result It is detected.

Specifically, after the first block chain determines the relevant content update of across the chain data processing request of this in the second account book, The root node of bis- Mei Keer tree is obtained from the second account book.Data processing using the root node of mono- Mei Keer tree to acquisition Content and the first operating result are detected, and determine that data processing content and the first operating result are not tampered with.Specially Second block chain in the way of above-mentioned building Mei Keer tree to the data processing content and the first operating result received again Then one Mei Keer tree of secondary building carries out the newly-built root node of Mei Keer tree and the root node of mono- Mei Keer tree pair Than.If the two is identical, show that data processing content and the first operating result are not tampered with；If the two is different, show to count According to there are data to be tampered in process content and the first operating result, then stop subsequent processing, sends and alert to the first block chain Message.

First block chain knows that the method that the second operating result is written in the second account book of the second block chain can be for actively Know, or passively know.Preferably, being here the first block chain pair to increase the flexibility across chain trading processing Second account book is monitored, and is specifically included:

First block chain checks the Status Flag of the second account book according to setpoint frequency；

First block chain discovery Status Flag changes, it is determined that the second operating result is written in the second account book.

In implementation process, Status Flag can be arranged for the second account book in the second block chain, such as sets in the second account book Flag bit is set, includes two character modes.If the data information recorded in the second account book changes, by tab character by working as Preceding character changes into another character.First block chain monitors the tab character of the second account book, i.e., by the second account book Tab character and the first block chain in the tab character that caches compare, if the two is identical, show the mark of the second account book Character is not changed, then the content of the second account book is not also changed；If the two is different, the content of the second account book is changed, the Second operating result is written with the second account book by two block chains, so that the first block chain obtains the second operation knot from the second account book Fruit, and the tab character in the first block chain is also accordingly changed.

It is exemplified below, current character is 1 on the flag bit of the second account book.When the second block chain is by the second operating result When the second account book is written, the character on flag bit is changed to 0 by 1 by the second block chain.It is corresponding with the second account book in first block chain Tab character be still 1.In this way, finding the tab character of the second account book during the first block chain monitors the second account book When inconsistent with the tab character that caches in the first block chain, determine that transaction data changes in the second account book, then from second The second operating result is obtained in account book, and the tab character cached in the first block chain is also changed to 0 by 1.

Further, it is specifically written with which the second operating result across chain transaction in order to identify, the second block chain is also Status Flag and the mark across chain transaction can be bound, to mutually be distinguished with other across chain transaction.

Corresponding, the second block chain, which is known, is written the first operating result in the first account book, comprising:

Second block chain checks the Status Flag of the first account book according to setpoint frequency；

Second block chain discovery Status Flag changes, it is determined that the first operating result is written in the first account book.

In implementation process, Status Flag can be arranged for the first account book in the first block chain, such as sets in the first account book Flag bit is set, includes two character modes.If the data information recorded in the first account book changes, by tab character by working as Preceding character changes into another character.Second block chain monitors the tab character of the first account book, i.e., by the first account book Tab character and the second block chain in the tab character that caches compare, if the two is identical, show the mark of the first account book Character is not changed, then the content of the first account book is not also changed；If the two is different, the content of the first account book is changed, the First operating result is written with the first account book by one block chain, so that the second block chain obtains the first operation knot from the first account book Fruit, and the tab character in the second block chain is also accordingly changed.

It is described in detail below with specific embodiment to above-mentioned process, the application scenarios of specific embodiment are that user a exists Bank account is offered in bank M, and user a offers game account in game company N, bank M maintenance has the first block Chain, game company's N-dimensional shield have the second block chain, and the application layer of the first block chain is deployed with the first across chain intelligence contract, and second The application layer of block chain is deployed with the second across chain intelligence contract, and the first across chain intelligence contract is opposite with the second across chain intelligence contract It answers.User a needs to transfer accounts from bank account to game account, and x is first, then user a sends one to bank M by cell phone application and transfers accounts Application, bank M then generate across a chain transaction request according to the application of transferring accounts, are uploaded to the first block chain.Therefore, the first block Chain is the source chain across chain transaction request, and the second block chain is object chain.Source chain by across the chain transaction request source chain transaction After the completion of execution, i.e., provides funds x member from the bank account transfer of user a, the transaction implementing result of source chain is written to the account of source chain In this.Object chain is monitored the account book of source chain, carries out the account book of the account book of object chain and source chain in the suitable period It is synchronous, to obtain transaction content of across the chain transaction request on object chain.Object chain should across chain transaction request in object chain Transaction execute after the completion of, i.e., game asset y are transferred into the game account of user a, wherein game asset y equal to fund X member.And it will be in the account book of the transaction implementing result of source chain write-in source chain.Source chain is monitored the account book of object chain, suitable Period the account book of the account book of source chain and object chain is synchronized, to obtain object chain to the processing result of transaction.Source The processing result of object chain is synchronized in the account book of source chain by chain.In addition, source chain is to source chain account book if object chain processing failure On transaction implementing result carry out rolling back action.

In above-mentioned application scenarios, source chain handles the process across chain transaction request as shown in fig. 4 a, comprising:

Step S401: source chain determines across chain transaction content by calling intelligent contract to parse across chain transaction request.Wherein, Across chain transaction content includes the address of the first across chain intelligence contract, account P address, object chain ID, the second across chain intelligence in application layer It can contract address, operating method and operation input parameter.It further include the digital signature for having bank M in across chain transaction request.

Step S402: source chain verifies the legitimacy of the digital signature；If verification passes through, S403 is thened follow the steps, is otherwise held Row step S404.

Step S403: source chain calls first to manage intelligent contract, detects the legitimacy across chain transaction content, comprising: source chain Whether deploy across chain intelligence contract, whether account P address legal in application layer, in account P remaining sum whether enough payment across chain Tranaction costs etc..If detecting successfully, S405 is thened follow the steps, it is no to then follow the steps S404.

Step S404: source chain will be labeled as failure across the processing result of chain transaction request, and cache.Step is executed later S407。

Step S405: source chain call the first across chain intelligence contract, execute transaction content in the first operating method, here for " producing fund x member ", obtained the first operating result caching, and across a chain transaction id is distributed simultaneously, bind above-mentioned across chain friendship The contents such as easy operating parameter, object chain ID, the second across chain intelligence contract address.Meanwhile corresponding mono- Mei Keer tree is generated, The root node of mono- Mei Keer tree is cached.

Step S406: it after source chain is to the content common recognition of caching, by the first account book of the content write-in source chain of caching, and changes The Status Flag of first account book.

Step S407: after source chain is to the content of caching common recognition, by the first account book of the content write-in source chain of caching, and to silver Row M feedback processing failure result terminates process.

It is as shown in Figure 4 b that object chain handles the process across chain transaction request, comprising:

Step S408: object chain monitors the Status Flag of the first account book, determines that the Status Flag of the first account book changes.

Step S409: object chain obtains across chain transaction content, the first operating result and the first plum gram from the first account book The root node of your tree.

Step S410: object chain calls second to manage intelligent contract, detects across chain transaction content, comprising: object chain ID is Whether whether correct, across the chain transaction content of correct, operating parameter and first operates knot for no correct, the second across chain intelligence contract address Whether fruit passes through the verification of Mei Keer tree.If detection passes through, S412 is thened follow the steps, if detection does not pass through, is thened follow the steps S411。

Step S411: object chain will be labeled as failure across the processing result of chain transaction request, and cache.Step is executed later S413。

Step S412: object chain calls the second across chain intelligence contract, executes the operating method formulated in across chain transaction content, The second operating result is obtained, and bis- Mei Keer tree is constructed based on the second operating result, by the second operating result and the second plum gram The root node caching of your tree.

Step S413: the second account book is written after reaching common understanding, by cache contents in object chain, and changes the shape of the second account book State mark.

Source chain continues with the process across chain transaction request as illustrated in fig. 4 c, comprising:

Step S414: source chain monitors the Status Flag of the second account book, determines that the Status Flag of the second account book changes.

Step S415: source chain obtains the root node of the second operating result and bis- Mei Keer tree from the first account book.If Second operating result is processing failure, thens follow the steps S417, no to then follow the steps S416.

Step S416: source chain calls first to manage intelligent contract, is operated using the root node of bis- Mei Keer tree to second As a result it tests.If upchecking, step S418 is executed, it is no to then follow the steps S417.

Step S417: the first operating result in the first account book is executed rolling back action by source chain, and to bank's M feedback processing Failure result, and terminate process.

Step S418: the first account book is written in the second operating result by source chain, and to bank M feedback processing successful result, and Terminate process.

In above-mentioned process, step S401- step S407 and step S408- step S413 and step S408- step S413 It is asynchronous process between step S413- step S418, i.e. source chain (or object chain) account that processing result is charged to block chain In this, without waiting for the processing result of other side.To improve the execution efficiency across chain transaction, overall processing is saved Duration.
