When client be respectively received the completion message of each node of the multichain and respectively send unlocking request it is more to thisAfter each node of chain, the unlocking request is received, is based on the unlocking request for this corresponding associated data of trading on this nodeIt is unlocked.
Concrete principle please refers to Program modual graph and Fig. 4 process about this method of following Fig. 3 about processing system 10The introduction of figure.
It is the Program modual graph of processing system 10 in Fig. 2 referring to shown in Fig. 3.The processing system 10 is divided into multipleModule, multiple module are stored in memory 12, and are executed by processor 13, to complete the present invention.The present invention is so-calledModule is the series of computation machine program instruction section for referring to complete specific function.
The processing system 10 can be divided into: locking module 101, pushing module 102 and unlocked state 103.
The locking module 101 when for carrying out across chain transaction between each node of multichain, receiving client and sending thisThe Transaction Information of secondary transaction and the client, to the locking request of corresponding associated data, are based on the locking based on the Transaction InformationRequest locks this corresponding associated data of trading on this node；
Wherein, associated data is the data that must be used in transaction, and the associated data of different transaction is different.For example, AMechanism belongs to different block chains from B mechanism, and the Transaction Information across chain transaction is for example are as follows: 1,000,000 are transferred accounts to B mechanism from A mechanism,Then corresponding associated data is A mechanism in the account information of account information, B mechanism on block chain on block chain.If eachData interlock success on a chain, then can execute transaction.The purpose of the locking of associated data is to prevent other users modification shouldData, so that Fail Transaction.
The pushing module 102 for executing intelligent contract based on the Transaction Information and associated data, and completes thisThis completion message traded is pushed to client after transaction；
Wherein, after completion of transactions, by the completion message active push of this transaction to client, so that the client on upper layerEnd can timely learning transaction results, do not need constantly to node polls transaction results.
The unlocked state 103, for being respectively received the completion message of each node of the multichain when client and dividingNot Fa Song unlocking request to each node of the multichain after, receive the unlocking request, based on the unlocking request by this node thisSecondary corresponding associated data of trading is unlocked.
After client receives the completion message of each node of the multichain, analyses whether to receive and all execute transactionNode completion message, with determine this transaction whether succeed, if it is, can send transmission unlocking request give the multichainEach node, this corresponding associated data of trading on this node is unlocked.In other embodiments, node is being handed overAfter being readily accomplished, voluntarily associated data can be unlocked.
As shown in figure 4, Fig. 4 is the flow diagram of method one embodiment of the present invention across chain transaction, the dress across chain transactionThe following steps of this method are realized when setting the processing system 10 stored in the 1 execution memory 12 of processor 13:
Step S1 when carrying out across chain transaction between each node of multichain, receives the transaction that client sends this transactionInformation and the client based on the Transaction Information to the locking request of corresponding associated data, based on the locking request by this nodeThis upper corresponding associated data of transaction is locked；
Wherein, each node that this Transaction Information traded is sent to multichain is subjected to across chain transaction by client, togetherWhen client send each node of the Transaction Information to the locking request of corresponding associated data to multichain.Associated data is to hand overThe associated data of the data that must be used in easily, different transaction is different, for example, A mechanism belongs to different blocks from B mechanismChain, the Transaction Information across chain transaction is for example are as follows: transfers accounts 1,000,000 to B mechanism from A mechanism, then corresponding associated data is that A mechanism existsThe account information of account information, B mechanism on block chain on block chain.
Wherein, if there is the associated data in block chain does not lock success, then this across chain Fail Transaction, needs againInitiate transaction.If the data interlock success on each chain, can execute transaction.The purpose of the locking of associated data is to preventOther users modify the data, so that Fail Transaction.
Step S2 executes intelligent contract based on the Transaction Information and associated data, and by this after completing this transactionThe completion message of transaction is pushed to client；
Wherein, each node of multichain is based on the Transaction Information and associated data executes intelligent contract, after completion of transactionsIt executes to submit and trades and Transaction Information is written on block chain account book, meanwhile, after completion of transactions, this completion traded is disappearedActive push is ceased to client, enables the client timely learning transaction results on upper layer, is not needed constantly to node pollsTransaction results.
Further, client can obtain transaction by way of long poll and complete message, i.e. client is sending thisAfter the Transaction Information of secondary transaction is to node, connection is idle and waits, when node generates completion message after completion of transactions, at onceIt returns and completes message to client.The operation allows for: when the case where unstable appearance transaction of message is lost is completed in push,Transaction has just fallen into unknowable state, and therefore, can be used simultaneously message ensures to be sent to mechanism, i.e. client while node pushesEnd carries out long poll.
Step S3, when client is respectively received the completion message of each node of the multichain and sends unlocking request respectivelyAfter each node of the multichain, the unlocking request is received, is based on the unlocking request for this corresponding pass of trading on this nodeConnection data are unlocked.
After client receives the completion message of each node of the multichain, analyses whether to receive and all execute transactionNode completion message, with determine this transaction whether succeed, if it is, can send transmission unlocking request give the multichainEach node, this corresponding associated data of trading on this node is unlocked.In other embodiments, node is being handed overAfter being readily accomplished, voluntarily associated data can be unlocked.
In one embodiment, on the basis of the above embodiments, the described locking request that is based on is by this friendship on this nodeThe step of easy corresponding associated data is locked, specifically includes: based on the locking request on the intelligent contract of scheduled lockingThis corresponding associated data of trading on this node is written, executes the locking intelligence contract to correspond to this transaction on this nodeAssociated data locked；
The described unlocking request that is based on is by the step of this corresponding associated data of trading is unlocked on this node, specificallyIt include: that this corresponding associated data of trading on this node is written on the intelligent contract of scheduled unlock based on the unlocking request,The unlock intelligence contract is executed so that this corresponding associated data of trading on this node to be unlocked.
Wherein, associated data locking can be realized with intelligent contract is locked, for example, transaction are as follows: user needs to modify numberAccording to A, then locking associated data can be LOCK-A, when LOCK-A success is written on block chain with the intelligent contract of locking,Indicate that data A is locked successfully.
Wherein, associated data unlock can be realized with intelligent contract is unlocked, for example, when needing to unlock data A, thenUnlocking associated data can be LOCK-A, when LOCK-A success is written on block chain with the intelligent contract of unlock, indicate data AIt unlocks successfully.
In one embodiment, on the basis of the above embodiments, the described locking request that is based on is by this friendship on this nodeThe step of easy corresponding associated data is locked, comprising: be written on the intelligent contract of scheduled locking based on the locking requestThis trade corresponding associated data and first identity information on this node, execute the locking intelligence contract on this nodeSecondary corresponding associated data of trading is locked；
