Embodiment 1

Fig. 1 shows the exemplary process diagram of the method for the consistency for realizing the transaction of transregional piece of chain.In the present embodiment, User to the first client 20 initiate transaction request, the first client 20 respectively with the block chain node 10 of the first block chain, clothes The block chain node 50 of business end system node 30, the second client 40 and the second block chain is communicated to complete to trade, tool Gymnastics is made as follows:

Firstly, the first client 20 receives Client-initiated transaction request, wherein transaction request includes the source account of transaction Address, transaction the first coding of assets and quantity, the source area block chain information of transaction, the transaction number of transaction, transaction purpose account Family address, the second coding of assets of transaction and quantity and the purpose block chain information of transaction.Herein, the first coding of assets It can be identical coding of assets from the second coding of assets and be also possible to different codings of assets, in presently disclosed embodiment In 1-3, it is illustrated using the first coding of assets from the second coding of assets as different codings of assets.

For example, in transaction request include transaction source account address, transaction the first coding of assets x and quantity be 1000, The source area block chain information (for example, first block chain) of transaction, the transaction number of transaction, the purpose account address of transaction, transaction Second coding of assets y and quantity are the purpose block chain information (for example, second block chain) of 950 and transaction.

Step 101: the first client 20 sends freeze request to the block chain node 10 of the first block chain, wherein freezes Request includes that the node of request source block chain calls the first method in the first intelligent contract to freeze in the source account of the transaction Tie this required amount of first assets of trading.

For example, freeze request includes requesting the block chain node 10 of the first block chain that the intelligence in intelligence and about A is called to close About method a1 is to freeze 1000 assets that account (that is, some account for belonging to the first block chain) coding of assets in source is x.

Step 102: the block chain node 10 of the first block chain executes freeze request；Specifically, the block of the first block chain Chain node 10 calls the first method in the first intelligent contract to freeze this required amount of first assets of trading in the account of source.

In the present embodiment, the block chain node 10 of the first block chain is by calling the intelligent contract side in intelligence and about A Method a1 freezes 1000 assets that coding of assets in the account of source is x on the first block chain.

Step 103: the block chain node 10 of the first block chain is freezing to notify to the transmission of the first client 20.Wherein, Freezing notice includes freezing the message of the first assets associated with transaction.

Step 104: receive freezing notice in the case where, the first client 20 to service end system node 30 send out Deliver easy initial information.Wherein, initial information includes at least the first coding of assets sum number of the source account address of transaction, transaction Amount (for example, 1000 assets that coding of assets is x), the source area block chain information (for example, first block chain) traded, the friendship traded The second coding of assets and quantity of the purpose account address, transaction easily number, traded are (for example, 950 moneys that coding of assets is y Produce), transaction purpose block chain information (for example, second block chain) and complete the transaction expense coding of assets and quantity (for example, 20 assets that coding of assets is x).

Step 105: in the case where service end system node 30 receives the initial information of transaction, being based on the initial information Set the original state of transaction.In the present embodiment, original state is that the source area block chain of the transaction is untreated and purpose block Chain is untreated.

Step 106: the block chain node 10 of the first block chain is sent completely to the first client 20 to be freezed to notify.

Step 107: in the case where receiving completion and freezing notice, the first client 20 is sent out to service end system node 30 It send and freezes assets message relevant to transaction in the account of source.

Step 108: receive freeze in the account of source to the transaction relevant assets message in the case where, server-side The state of the transaction is updated to the first stateful transaction from original state by system node 30.In the present embodiment, the first transaction shape State is that freeze the purpose block chain traded and traded untreated for the source area block chain of transaction.

Step 109: service end system node 30 sends request execution transaction in purpose account to the second client 40 and moves Make message.

In the present embodiment, request increases by 950 assets that coding of assets is y in purpose account.

Step 110: the second client 40 is sent to service end system node 30 executes transaction movement response, to show to receive Transaction movement message is executed in purpose account to request.

Step 111: the second client 40 is sent to the block chain node 50 of the second block chain increases request.In the present embodiment In, increase request includes that the node of request purpose block chain calls the first method in the second intelligent contract in the transaction Increase this required amount of second assets of trading in purpose account.

Step 112: the block chain node 50 of the second block chain calls the first method in the second intelligent contract in the friendship Increase this required amount of second assets of trading in easy purpose account.

For example, the block chain node 50 of the second block chain is by calling the intelligent contract method b1 in intelligence and about B the Increase by 950 assets that coding of assets is y in purpose account on two block chains.

Step 113: the block chain node 50 of the second block chain is sent completely increase notice to the second client 40.

In the present embodiment, it completes to increase that the block chain node 50 including the second block chain is notified to have called up intelligent contract Intelligent contract method b1 in B increases by 950 assets that coding of assets in purpose account is y on the second block chain.

Step 114: the second client 40 is sent in completion transaction movement in purpose account to service end system node 30 and disappears Breath.

Step 115: the state of transaction is updated to the second stateful transaction from the first stateful transaction by service end system node 30. Wherein, the second stateful transaction is that the source area block chain of transaction freezes transaction and purpose block chain completes transaction.

Above-mentioned steps show the friendship that service end system node 30 has been acknowledged that the block chain node 50 of the second block chain is completed Easily movement, realizes the purpose of a wherein side for transaction.

Step 116: service end system node 30 sends request to the first client 20 and executes transaction movement in the account of source Message.

Step 117: receive request in the account of source execute transaction movement message in the case where, the first client 20 to Request is reduced in the transmission of block chain node 10 of first block chain.Wherein, the node that request includes request source block chain is reduced to call Second method in first intelligent contract reduces this required amount of first assets of trading in the source account of the transaction.

Step 118: the block chain node 10 of the first block chain calls the second method in the described first intelligent contract in institute It states and reduces this required amount of first assets of trading in the source account of transaction.

In the present embodiment, the block chain node 10 of the first block chain calls the intelligent contract method a2 in intelligence and about A 1000 assets that coding of assets is x, tranaction costs of 20 assets therein as transaction are reduced in the source account of transaction.

Step 119: the block chain node 10 of the first block chain be sent completely to the first client 20 reduce it is logical.

In the present embodiment, it completes to reduce notice to include that the block chain node 10 of the first block chain has called up intelligent conjunction Intelligent contract method a2 in about A has reduced 1000 assets that coding of assets is x in the source account of transaction.

Step 120: in the case where receiving completion and reducing notice, the first client 20 is sent out to service end system node 30 Send the completion transaction movement message in the account of source.

Step 121: in the case where receiving the completion transaction movement message in the account of source, the first client 20 will transaction State be updated to third stateful transaction from the second stateful transaction.Wherein, third stateful transaction is that the source area block chain of transaction is completed It trades and purpose block chain completes transaction.

Above-mentioned steps show the friendship that service end system node 30 has been acknowledged that the block chain node 50 of the second block chain is completed Easily movement realizes the purpose of wherein another party of transaction, namely transaction successfully completes.

Technical solution disclosed in embodiment 1 shows in all participants (including the first client 20, traded across chain The block chain node 10 of one block chain, service end system node 30, the second client 40 and the second block chain block chain link 50) point works normally in the case that, the consistency and timeliness of the transaction across chain transaction are realized.

Embodiment 2

Fig. 2 shows the exemplary process diagrams of the method for the consistency for realizing the transaction of transregional piece of chain.In the present embodiment, User to the first client 20 initiate transaction request, the first client 20 respectively with the block chain node 10 of the first block chain, clothes The block chain node 50 of business end system node 30, the second client 40 and the second block chain is communicated, and is held not receiving Row transaction movement is responded or do not received to be completed under transaction movement message scenario in purpose account, and concrete operations are as follows:

Step 201- step 209 is similar to the step 101- step 109 in embodiment 1, and details are not described herein.

In the present embodiment, the response of execution transaction movement is not received in service end system node 30 or receive execution Transaction movement is responded but is not received and completes to execute step 210 in the case where transaction movement message in purpose account.

Step 210: when reaching the given threshold period, transaction number of the service end system node 30 based on the transaction Query messages are sent to the second client 40.

In the present embodiment, the given threshold period is can be delayed most according to the execution duration of general transaction, transaction What big value etc. was calculated.The query messages include at least whether the transaction with the transaction number is completed in purpose account It trades and/or whether the transaction request (for example, request executes transaction movement message in purpose account) with the transaction number It receives.

In the case where service end system node 30 does not receive the feedback message for completing transaction movement in purpose account, Service end system node 30 sends the query messages to the second client 40 again.

In the present embodiment, the different periods can be spaced to the second client 40 transmission query messages.For example, first The secondary query messages that send can send query messages three days after the completion step 209 of service end system node 30, second It can be seven days after first time transmission query messages, if setting inquiry times threshold value is that three times, third time sends and looks into Asking message can be ten day after second of transmission query messages.

Step 211: the feedback message of transaction movement and transmitted is completed in the purpose account not receiving In the case that query messages number is more than setting inquiry times threshold value, service end system node 30 is asked to the transmission of the first client 20 Seek the message that thaws out the frozen assets in the account of source.

In the present embodiment, service end system node 30 can send request to the first client 20 and thaw in the account of source This required amount of first assets message of trading.1000 moneys that code is x for example, request thaws out the frozen assets in the account of source It produces.

Alternatively, service end system node 30 can also send request to the first client 20 and reduce this in the account of source The required amount of assets of the tranaction costs of transaction and request thaw in the account of source this transaction volume residual the first assets Message.For example, 20 assets that tranaction costs coding of assets is x are reduced in request in the account of source and the code that thaws out the frozen assets is 980 assets of x.

Step 212: the first client 20 sends request of thawing to the block chain node 10 of the first block chain,

In the present embodiment, request of thawing includes that the block chain node 10 of the first block chain of request calls in intelligence and about A Intelligent contract method a3 thaw out the frozen assets in the account of source code be x 1000 assets；Alternatively, it calls in intelligence and about A Intelligent contract method a2 reduced in the account of source tranaction costs coding of assets be x 20 assets and call intelligence and about A In intelligent contract method a3 thaw out the frozen assets in the account of source code be x 980 assets.

Step 213: the block chain node 10 of the first block chain executes request of thawing.

In the present embodiment, the block chain node 10 of the first block chain calls the intelligent contract method a3 in intelligence and about A The code that thaws out the frozen assets in the account of source is 1000 assets of x；Alternatively, the intelligent contract method a2 in intelligence and about A is called 20 assets that tranaction costs coding of assets is x are reduced in the account of source and call the intelligent contract method in intelligence and about A A3 thaw out the frozen assets in the account of source code be x 980 assets.

Step 214: the block chain node 10 of the first block chain is sent completely defrosting notice to the first client 20.In this reality It applies in example, wherein completing to thaw notifies to include that the block chain node 10 of the first block chain has called up the intelligence in intelligence and about A Contract method a3 thawed in the account of source coding of assets be x 1000 assets；Alternatively, it has called up in intelligence and about A Intelligent contract method a2 reduced in the account of source tranaction costs coding of assets be x 20 assets and have called up intelligence Intelligent contract method a3 in about A thawed in the account of source coding of assets be x 980 assets.

Step 215: in the case where receiving completion defrosting notice, the first client 20 is sent out to service end system node 30 It send and completes the message that thaws out the frozen assets in the account of source.

Step 216: receive in the account of source complete thaw out the frozen assets message in the case where, service end system node 30 will The state of transaction is updated to the 4th stateful transaction from the first stateful transaction.In the present embodiment, the 4th stateful transaction is the transaction Source area block chain cancelled and purpose block chain is undetermined.

Technical solution disclosed in embodiment 2 shows in the second client 40 and/or the second block chain traded across chain In the case that abnormality occurs in block chain node 50, a side (for example, first client 20) for transaction can be with corresponding area Block chain node (for example, block chain node 10 of the first block chain) communication is to Cancel Transaction (for example, thawing in order to which this transaction exists The assets freezed in the account of source), to guarantee the flexibility of transaction, and without entering Infinite Cyclic waiting in trading processing State also ensures the agility of trading processing, and is continuously updated the shape currently traded in service end system node 30 State, to determine the consistency traded in both parties.

Firstly, the first client 20 receives Client-initiated transaction request, then such as step 101- step in embodiment 1 109 or embodiment 2 in shown in step 201- step 209, the block chain node 10 and clothes of the first client 20, the first block chain Business end system node 30 is operated respectively, so that the transaction assets in the account of source are frozen, and service end system node 30 Recording current stateful transaction is that " the source area block chain of the transaction freezes transaction and the purpose block chain of the transaction is not located Reason ".Then concrete operations are as follows:

Step 320: when reaching the given threshold period, service end system node 30 is based on the transaction number of transaction to Two clients 40 send query messages.In the present embodiment, the query messages are for inquiring whether the second client 40 receives Request executes transaction movement request in purpose account.In addition, the given threshold period in the present embodiment can be according to reality Transaction is set.

Step 321: the second client 40 is sent to service end system node 30 executes transaction movement response.

Step 322: do not receive purpose account complete transaction movement feedback message in the case where, service end system Node 30 sends query messages to the second client 40 again.Whether query messages sent in this step are for inquiring in mesh Account in complete transaction movement.

Step 323: the second client 40 is sent to the block chain node 50 of the second block chain increases request.

Step 324: completing the feedback message of transaction movement in purpose account and transmitted inquiry disappears not receiving Ceasing number is more than in the case where setting inquiry times threshold value, and service end system node 30 is by the state of transaction from described in embodiment 1 The first stateful transaction be updated to the 6th stateful transaction.In the present embodiment, the 6th stateful transaction is that the source area block chain of transaction freezes It makes friends with easily and purpose block chain is undetermined.

Step 325: service end system node 30 sends to the first client 20 and requests the message that thaws out the frozen assets in the account of source.

In the present embodiment, service end system node 30 can send number needed for this transaction of requesting to thaw in the account of source First assets message of amount；Or the required amount of money of tranaction costs that this transaction is reduced in request in the account of source can be sent It produces and the message of the first assets of this transaction volume residual of requesting to thaw in the account of source.

For example, service end system node 30 can be sent to the first client 20 requests the code that thaws out the frozen assets in the account of source For 1000 assets of x.Alternatively, service end system node 30 can also send request in the account of source to the first client 20 Reduce 20 assets that tranaction costs coding of assets is x and 980 assets that the code that thaws out the frozen assets is x.

Step 326: the first client 20 sends request of thawing to the block chain node 10 of the first block chain.

For example, the block chain node 10 that request of thawing includes the first block chain of request calls the intelligence in intelligence and about A to close About method a3 thaw out the frozen assets in the account of source code be x 1000 assets；Alternatively, the intelligence in intelligence and about A is called to close About method a2 reduces 20 assets that tranaction costs coding of assets is x in the account of source and calls the intelligence in intelligence and about A Contract method a3 thaw out the frozen assets in the account of source code be x 980 assets.

Step 327: the block chain node 10 of the first block chain executes above-mentioned defrosting request.

Step 328: the block chain node 10 of the first block chain sends notice of thawing to the first client 20.In the present embodiment In, completing to thaw notifies the block chain node 10 including the first block chain that the intelligent contract method a3 in intelligence and about A is called to exist The code that thaws out the frozen assets in the account of source is 1000 assets of x；Alternatively, the intelligent contract method a2 in intelligence and about A is called to exist 20 assets that tranaction costs coding of assets is x are reduced in the account of source and call the intelligent contract method a3 in intelligence and about A The code that thaws out the frozen assets in the account of source is 980 assets of x.

Step 329: the first client 20 is sent in the account of source to service end system node 30 and completes the message that thaws out the frozen assets.

Step 330: receive in the account of source complete thaw out the frozen assets message in the case where, service end system node 30 will The state of transaction is updated to the 4th stateful transaction from above-mentioned first stateful transaction.In the present embodiment, the 4th stateful transaction is this The source area block chain of transaction has cancelled and purpose block chain is undetermined.
