Description

A kind of core algorithm of the double-chain block chain the Internet model merchandised across chain

Technical field

The present invention relates to the block chain Internet technical field for financial system, especially with distributed block chain The Internet architecture.

Background technology

((Blockchain, BC) is distributed data base system to block chain, it will be understood that to be safeguarded jointly by multiple nodes Distributed account book technology (Distributed Ledger Technology, DLT), be characterized in being difficult distorting, be difficult puppet Make, can review.(Internet of Blockchians) is a kind of value network built based on block chain for block chain internet Network, must have high-performance, security, privacy, scalability, intercommunity, alterability, fault-tolerance, manageability and complete Property

Existing block chain internet, such as universe net (Cosmos), the mostly structure of centralization, its intermediate chain are in one Concentric mechanism, then the calculating of intermediate chain and communication link easily turn into the bottleneck of block chain internet.In addition, its each chain is required for Maintain the uniformity of oneself, and intermediate chain be also required to dynamic maintain and each participation chain between uniformity, and then one across Chain transaction needs a plurality of participation chain to be maintained jointly with intermediate chain so that the speed of service of block chain slows down.

The content of the invention

In order to overcome the problem of above-mentioned existing link network (such as Cosmos) efficiency applied to financial system is slower, this hair It is bright to provide a kind of core algorithm of the double-chain block chain the Internet model merchandised across chain, it is possible to achieve concurrent operation, improve The operational efficiency and transactions velocity of system, while ensureing system conformance.

The technical solution adopted in the present invention is that a kind of core of the double-chain block chain the Internet model merchandised across chain is calculated Method, it is characterised in that the model is as shown in figure 1, include consisting of part：

(1) chain (Participant Blockchain, PPC) is participated in, one or more financial institutions is represented or finance is single Position, can be included by one or more node；

(2) intermediate chain (Inter-chain Blockchain, ICC), represents an intermediary agency, itself is also one Financial institution, can also play CCP (Central Counterparty, central analogue) effect, can pass through TBC (Trading Blockchain, transaction block chain) is traded with participating in chain；

(3) one or more intermediate chain can be connected between every two participation chains, every intermediate chain can connect two to a plurality of Chain is participated in, and the transaction between two or more pieces participation chain is completed by intermediate chain, it includes two kinds of trade modes, with suitable for not Same demand (completing transaction, or non real-time but efficient transaction immediately)：

(3a) real-time deal (real-time transaction)：Two extremely a plurality of participation chain can pass through an intermediate chain Carry out real-time deal, each transaction of the execution of intermediate chain immediately；

(3b) Multi-Lateral Netting settles accounts (multilateral netting)：Every intermediate chain is at the end of each billing cycle Multi-Lateral Netting clearing are carried out, many transaction (tentative transaction) undetermined are handled together, plays a part of CCP, subtracts Few transaction count, improves trading efficiency；

(4) some multiple financial institutions constitute a distributed network, every chain in the form of participating in chain and intermediate chain The uniformity of oneself is safeguarded, the uniformity between chain and chain does not need central tissue to manage, and is able to run parallel, improve transaction Efficiency and network operation speed；New financial unit can be easily added or leave at any time network, with scalability, support big Scale network and high transaction volume.

It is preferred that, for part (1), the link network comprising it is some participate in chains, each participation chain represent one or Multiple financial units, can include some multinodes, each node store full detail of the financial unit；Participate in the complete of chain Portion or part of nodes have franchise (whole nodes and part of nodes may participate in ballot both of which and are applied to this patent), Concurrent Byzantine failure tolerance agreement (CBFT, Concurrent Byzantine Fault are used between each node Tolerance) or practical Byzantine failure tolerance agreement (PBFT, Practical Byzantine Fault Tolerance) or The algorithm of other Byzantium (Byzantine) common recognition agreements or database things uniformity is (as used database things one The algorithm of cause property, then can not investigate the node lied, so that being the consistency algorithm of a reduction), to ensure each node Between information uniformity and the difficulty property altered, it is ensured that every participation chain uniformity of itself.

It is preferred that, for part (2), the link network includes some many intermediate chains, and each intermediate chain includes an ABC (Account Blockchain, account block chain) and two to more TBC (Trading Blockchian, block of merchandising Chain), schematic diagram is shown in Fig. 3 (two participation chains by TBC-ABC-TBC structures be connected), Fig. 4 (2 TBC), Fig. 5 (3 TBC) with Fig. 6 (4 TBC).ABC is responsible for storing and safeguarding accounts information, and TBC is then responsible for performing transaction.Each ABC and TBC are included Some multiple nodes, its all or part of node has franchise, and (whole nodes and part of nodes may participate in both feelings of voting Condition is applied to this patent), protected using Byzantine failure tolerance agreement (or the database things agreement weakened) between each node Demonstrate,prove the uniformity of information and the difficulty property altered between each node, it is ensured that each ABC chain and each TBC's itself is consistent Property.ABC, TBC double-strand model applied for patent by Beijing Tian De Science and Technology Ltd.s, and had been carried out：One kind is based on area DVP settlement methods (A of CN 106504085), a kind of block for storing Transaction Information and accounts information respectively of block chain technology Chain (A of CN 106503992).The intermediate chain has two kinds of memory modules：

(1) physics and logic isolation：Every TBC chain and ABC chains are stored in different servers, every when being known together TBC chains and ABC chains carry out the common recognition of oneself respectively, as shown in figure 15, and the pattern can ensure separate between every chain；

(2) logic isolation：Every TBC chain and ABC chains are stored in the different storage zone of same server, but are total to Every TBC chain and ABC chains still carry out the common recognition of oneself respectively during knowledge, as shown in figure 16, and the pattern can also ensure between every chain It is separate, and be more easy to than pattern (1) to carry out the information transmission between chain and chain.

It is preferred that, for part (3), in the link network, one can be connected between every two participation chains in a plurality of Between chain, interchain can connect two to a plurality of participation chains in the middle of every, and complete two or more pieces by intermediate chain and participate between chain Transaction, the link network can realize two kinds of different trade modes, complete to merchandise immediately to meet, and non real-time but efficiently merchandise this Two kinds of different demands：

(1) real-time deal：Two can carry out real-time deal to a plurality of participation chains by intermediate chain, and intermediate chain is instant Each transaction is performed, real-time settle accounts calculation is realized；

(2) Multi-Lateral Netting is settled accounts：Every intermediate chain carries out many at the end of each billing cycle (one hour or one day etc.) Side netting, handles many transaction (tentative transaction) undetermined, reduces the number of times of settle accounts calculation, improve together Trading efficiency, because a settle accounts calculation can solve large quantities of transaction, but this method can not realize real-time settle accounts calculation.

It is preferred that, for (1) real-time deal, the core process of such a trade mode is as shown in Fig. 7 and Figure 11.The transaction mould Comprising procedure below, (the following high-level for step is described formula, and detailed description is shown in《Specification》In《Embodiment》In Arthmetic statement and false code), its flow is as shown in Fig. 8 and Figure 12.

Mould formula (II), is shown in Figure 11：

Procedure below (2a) is performed simultaneously with process (2b)；

(2a) intermediate chain 1 (ICC1) returns to the information of the transaction request success or not to chain 1 (PPC1) is participated in；

(2b) intermediate chain 1 (ICC1) sends transaction request to chain 2 (PPC2) is participated in；

If the transaction of process (1) is initiated successfully, after process (2a) is finished with process (2b), the stateful transaction is marked For (tentative) undetermined；

It is finished in above-mentioned mould formula (II) after (2a), other operations can be carried out by participating in chain 1 (PPC1), be realized clog-free Operation.

(3) participate in chain 2 (PPC2) and send whether the transaction request succeeds by participation chain 2 (PPC2) to intermediate chain 1 (ICC1) The message of receiving, if it is, the proof of the transaction can be received by sending the participation chain 2 (PPC2) to intermediate chain 1 (ICC1)；

Procedure below (4a) is performed simultaneously with process (4b)；

(4a) intermediate chain 1 (ICC1) informs that the transaction meets execution condition to chain 1 (PPC1) is participated in, and can perform；

(4b) intermediate chain 1 (ICC1) informs that the transaction meets execution condition to chain 2 (PPC2) is participated in, and can perform；

Two participation chains are received after intermediate chain 1 (ICC1) message, are immediately performed the intermediate chain 1 (ICC1) with participating in chain 1 (PPC1) and undetermined transaction of the intermediate chain 1 (ICC1) with participating in chain 2 (PPC2), until it is whole run succeeded untill, that is, complete Merchandise (commit).

It is preferred that, for (2) plant trade mode, Multi-Lateral Netting clearing, core process such as Fig. 9 of such a trade mode and Shown in Figure 13.Comprising procedure below, (the following high-level for step is described the trade mode, and detailed description is shown in《Specification》In 《Embodiment》In arthmetic statement and false code), its flow is as shown in Figure 10 and Figure 14.

Following process (2) is divided into both of which：

Mould formula (I), is shown in Fig. 9：

If the transaction is initiated successfully, after process (2) is finished, the stateful transaction is labeled as pre- (pre- undetermined tentative)；

Mould formula (II), is shown in Figure 13：

Procedure below (2a) is performed simultaneously with process (2b)；

If the transaction is initiated successfully, after process (2a) is finished with process (2b), the stateful transaction is labeled as to treat in advance Fixed (pre-tentative)；

If the request is successfully received, the stateful transaction is labeled as (tentative) undetermined：

Procedure below (4a) is performed simultaneously with process (4b)；

At the end of the transaction waits the billing cycle, implementation procedure (5)；

(5) now the billing cycle terminates, and stops all transaction and transaction undetermined that will starting or initialize, Complete the transaction that is carrying out, and it is undetermined to being marked as within all billing cycles by intermediate chain 1 (ICC1) (tentative) transaction carries out Multi-Lateral Netting clearing, is merchandised (commit) stage into completion.

It is preferred that, the schematic diagram that an intermediate chain is traded by ABC and TBC and two participation chain is shown in Fig. 2.For process (1) to (4), to its process of exchange and during ABC and TBC effect be described as follows：When an intermediate chain is joined with one When being traded with chain, it is possible to use TBC is connected with participating in one or more node of chain, it is responsible for handling the participation by TBC The transaction of chain and intermediate chain, in every intermediate chain, there is an ABC, is responsible for storage with safeguarding accounts information, ABC and each TBC It is connected, each TBC is connected with a participation chain being connected with the intermediate chain, is responsible for being traded；Whenever a TBC is sent out to ABC Deliver letters before breath, or when ABC is sent before information to TBC, the TBC or ABC oneself will be known together first；When the ABC or TBC is received To after information (such as asking), it will all be known together first by each node；When a TBC to participate in chain send information before, It need to be known together first；When a TBC is received from the information for participating in chain, also need first to be known together.Only when each is total to After knowledge passes through, it could run.

It is preferred that, when a chain is to another chain transmission information, its transfer mode is transmission in bulk, chain it is each Individual node is respectively to each node transmission information of another chain, to prevent that some or certain several nodes from practising fraud and influences whole The correctness of transmitting procedure.For example, when participating in chain 1 (PPC1) to during TBC1 transmission requests, if participating in chain 1 (PPC1) has m Node, respectively P1, P2 ..., Pm, TBC1 have a n node, respectively T1, T2 ..., Tn, then by Pi (i=1,2 ..., n) Respectively to T1, T2 ..., Tn sends request, and all nodes send m*n request altogether.

It is preferred that, carried out below to two participation chains, to participate in chain 1 (PPC1) with participating in chain 2 (PPC2) by intermediate chain Transaction, for the brief description of process (1) to each step of (4), detailed description is shown in《Specification》In《Specific embodiment party Formula》In arthmetic statement and false code.In process of exchange, whenever a chain will send information (as transaction please to another chain Ask, successful information of merchandising etc.) before, be required for oneself being known together first, decide whether to perform the instruction of the information；Whenever one When chain have received the information of another chain, it is required for being verified and being known together first, to decide whether to receive or perform the information, Part common recognition process is eliminated in arthmetic statement and false code, and (clipped can be solved according to the patented technology issued in the past： A kind of DVP settlement methods (A of CN 106504085) based on block chain technology, one kind distinguish Transaction Information and accounts information The block chain (A of CN 106503992) of storage, this patent is not repeated to discuss), remain important common recognition process.

(1) chain 1 (PPC1) is participated in initiate to merchandise to intermediate chain 1 (ICC1)：

(1.1) participate in chain 1 (PPC1) (financial institution) and initiate transaction：Participate in ballot (CBFT or PBFT of the chain inside Deng Byzantine failure tolerance common recognition agreement or database things agreement) decide whether to initiate transaction, if so, participating in chain 1 (PPC1) to this Certification (using digital signature etc.) is encrypted in Transaction Information, and in the TBC1 that will be used, (TBC1 exists in this selected transaction It is connected in intermediate chain and with participating in chain 1 (PPC1)), and the Transaction Information for encrypt certification is sent to the TBC1；If it is not, Error message is returned to chain 1 (PPC1) is participated in, and is failure (failure) by the process markup；

(1.2) intermediary agency's checking information：TBC1 receives Transaction Information, and sends request to ABC, and ABC is received after request, (using digital signature etc.) is verified to Transaction Information, if being proved to be successful, the accounts information of the participation chain is transmitted to ABC； If authentication failed, error message is returned, and preceding step is marked as (failure)；

(1.3) TBC1 transaction undetermined：Each node in TBC1 carries out ballot to the transaction and builds block, and is by the transaction (pending) state undetermined.

Following process (2) is divided into both of which：

Mould formula (I)：

(2) intermediate chain 1 (ICC1) sends transaction request to chain 2 (PPC2) is participated in：

(2.1) intermediate chain (ICC1) transmission transaction：(CBFT or PBFT etc., which are visitd, to be accounted for for ballot of the intermediate chain (ICC1) inside The fault-tolerant common recognition agreement in front yard or database things agreement) decide whether to chain 2 (PPC2) transmission transaction is participated in, if so, then intermediate chain (ICC1) certification (using digital signature etc.) is encrypted to the transaction, and selectes the TBC2 that will be used in this transaction and (is somebody's turn to do TBC2 is connected in intermediate chain and with participating in chain 2 (PPC2)), and the Transaction Information for encrypt certification is sent to this TBC2；If it is not, then returning to error message, and preceding step is marked as (failure)；

(2.2) chain 2 (PPC2) checking information is participated in：TBC2 is sent to by encrypting certification to chain 2 (PPC2) is participated in The checking request of transaction, participates in transaction of the chain 2 (PPC2) to the request and is verified (using digital signature etc.), if checking is logical Cross, then participate in chain 2 (PPC2) and then carry out inside chooses whether receive the transaction in a vote；If authentication failed, failure information is returned, And mark preceding step for (failure).

Mould formula (II)：

(2a) intermediate chain 1 (ICC1) returns to the information of transaction success or not undetermined to chain 1 (PPC1) is participated in：

If stateful transaction (pending) undetermined sets successfully, transaction undetermined successfully letter is returned to chain 1 (PPC1) is participated in Breath, TBC1 is then etc. pending (pending)；If Fail Transaction, to the information for participating in chain 1 (PPC1) return Fail Transaction, and Preceding step is marked for (failure).

(2b) is carried out simultaneously with (2a), with the process (2) in mould formula (I).

(3) participate in chain 2 (PPC2) and send whether the transaction request succeeds by participation chain 2 (PPC2) to intermediate chain 1 (ICC1) The message of receiving, if it is, the proof of the transaction can be received by sending the participation chain 2 (PPC2) to intermediate chain 1 (ICC1)：

(3.1) voted successfully if participating in chain 2 (PPC2), agreement receives the transaction, then is returned successfully to intermediate chain 1 (ICC1) Information, and carry out (3.2)；Otherwise, then failure information is returned to intermediate chain 1 (ICC1), and preceding step is marked is (failure)；

(3.2) participation chain 2 (PPC2) sends the participation chain 2 (PPC2) to intermediate chain 1 (ICC1) can receive the transaction Prove, such as participating in chain 2 (PPC2) there are enough related resources to complete this transaction, and by TBC2 execution undetermined with participating in chain 2 (PPC2) transaction is set to (pending) state undetermined.

(4) intermediate chain checking participates in the information that chain 2 (PPC2) is returned, and determines whether the transaction meets execution condition, if It is then to carry out (4a) and (4b)；Whether cancel transaction undetermined if it is not, then being chosen in a vote, and preceding step marked for Failure (failure).

(4b) intermediate chain 1 (ICC1) informs that the transaction meets execution condition to chain 2 (PPC2) is participated in, and can perform.

In order to improve it is existing for financial system design link network result can not parallel work-flow, efficiency is slow the problem of, mesh The distributed new chain net structure model of preceding design, has the following advantages that：

(1) parallel work-flow is supported：The model is due to being a fully distributed framework, and all chains are on this model It can parallel run, improve the speed of service of whole financial system：Because different participation chains can be from different intermediate chains Be traded, and the transaction handled by different participation chain can be carried out simultaneously, without every transaction all by one it is total in Mechanism is entreated, the trading volume and load capacity of each intermediary agency all mitigate significantly, it is possible to carry out parallel work-flow, and then improve friendship Easy efficiency, has speeded the speed of transaction.

(2) Multi-Lateral Netting is settled accounts：Two or a plurality of participation chain by an intermediate chain when being traded, and intermediate chain is to multiple Transaction carries out mutual offset netting, reduces the treating capacity of clearing, also mitigates the difficulty of large-scale transaction, improves the speed of transaction Degree, improves market efficiency.

(3) scalability：Any number of financial institution and intermediary agency can be easily added the chain net structure at any time, And connected the new financial unit that will be added with existing intermediary agency by TBC, this allows the link network to expand Open and adapt to catenet and high transaction volume.

(4) supervision is supported：The account book record being difficult to tamper with, have recorded real process of exchange, facilitates government department to supervise Check account.

(5) transaction record is separated with remaining sum account：Account block chain (ABC) and trading post in the middle chain structure of the model The separated design of block chain (TBC) and the mechanism known together respectively are applied to financial system, improve Privacy Safeguarding and friendship Easy efficiency.

(6) different memory modules：Account block chain (ABC) is with merchandising block chain (TBC) no in the intermediate chain of the model Go for different application scenarios with memory module.

(7) basic principle of link network is ensure that, including：(a) high-performance, complete distributed frame supports each intermediary agency Parallel operation, improves the trading efficiency of network；(b) data reliability (being difficult to tamper with property, security), each node is used to visit and accounted for Front yard protocol for error tolerance come ensure each node uniformity and being difficult to tamper with property；(c) protect the information inside privacy, each chain can not By outside acquisition；(f) scalability, any financial institution can be easily added the link network at any time, and due to concurrent operation, increase Plus new financial institution does not result in communication obstruction；(e) completeness, every chain can follow the trail of its completeness, once a section Point cheating, its completeness will be reduced, it is possible to be tracked and checked.

Embodiment

In order to be better understood from technical scheme provided in an embodiment of the present invention, also technology preferably with the embodiment of the present invention Scheme is contrasted, and by algorithm and false code combination accompanying drawing, the present invention is further described first below.

The embodiment of this kind of double-chain block chain the Internet model (spun gold monkey model) merchandised across chain is mainly wrapped Include following three part：

(1) whole network, which is started from scratch, builds；

(2) merchandise：One participation chain is traded by an intermediate chain with another participation chain；

(3) new chain adds network.

Start from scratch for (1) whole network and build, its input includes some a plurality of intermediate chain (Inter-chain Represented in Blockchain, false code by ICC), some a plurality of participation chains are (in Participant Blockchain, false code Represented by PPC), and each bar participate between chain and intermediate chain whether the relation that should be connected, detailed process is as follows.

(1), will be all for so the chain of the network will be added, all participation chains are put into a participation chain set Intermediate chain be put into an intermediate chain set；

(2) for each intermediate chain in intermediate chain set, and every two participation chains in chain set are participated in, utilized The chain that will reach and the relation of interchain of the known network, judge：If the intermediate chain will connect with this two participation chains Connect, then two participation chains of the intermediate chain and this are set up respectively is connected；Otherwise, other chains are continued with.

The main algorithm of the process is presented below in the form of false code, is designated as algorithm 0, sets up network.

For (2) transaction：One participation chain is traded by an intermediate chain with another participation chain, and schematic diagram is visible Fig. 2.It, which is inputted, includes intermediate chain 1 (ICC1), participates in chain 1 (PPC1) with participating in chain 2 (PPC2).Participate in chain 1 (PPC1) and be responsible for hair Transaction is played, and is traded by intermediate chain 1, is responsible for receiving the transaction by participation chain 2 (PPC2).For example, participate in chain 1 (PPC1) to The transaction that chain 2 (PPC2) carries out convertibility of dollar into gold is participated in, chain 1 (PPC1) is participated in and initiates to provide dollar and exchange the friendship of gold for Easily there is provided the certain number of amount of money, process of exchange is performed by intermediate chain 1, is responsible for receiving this dollar simultaneously by participation chain 2 (PPC2) Gold is provided.

For merchandising each time, contain real-time deal and settle accounts two kinds of situations with Multi-Lateral Netting, its particular transactions process is such as Under.

(1) participation chain 1 (PPC1) is voted by each node to its inside (uses CBFT or PBFT or other Byzantium's common recognition agreement or database things agreement) decide whether to initiate this transaction, if voted successfully, into the (2) step；If ballot failure, returns to error message；

(2) selecting one is used to participate in the TBC1 that chain 1 (PPC1) performs transaction with intermediate chain 1, and the TBC1 is intermediate chain 1 A part；

(3) participate in chain 1 (PPC1) and send transaction request, as process (1) then to TBC1；

(4) algorithm 2 is called, (using electronic signature etc.) is verified by 1 pair of transaction request of intermediate chain, if verified into Work(, then into (5) portion；If authentication failed, error message is returned to chain 1 (PPC1) is participated in；

(5) intermediate chain 1 is voted each node of its inside (is known together using CBFT or PBFT or other Byzantium Agreement or database things agreement) decide whether that the transaction can be performed, if voted successfully, into (6) step；Such as Fruit ballot failure, then return to the information for failure of voting to participation chain 1 (PPC1), and by steps all before labeled as " mistake Lose "；

(6) stateful transaction participated between chain 1 (PPC1) and intermediate chain 1 (ICC1) is set to " undetermined " (pending)；

(7) if necessary to real-time deal, then the stateful transaction is labeled as " undetermined " (tentative)；If necessary to many Side netting, then be labeled as " pre- undetermined " (pre-tentative) by the stateful transaction；

(8) if mould formula (I), then algorithm 3 is called, center chain 1 (ICC1) begins preparing for initiating to participation chain 2 (PPC2) Transaction request, as process (2)；If process (2) return center chain 1 (ICC1) to participate in chain 2 (PPC2) transaction request into Work(, then into (9) step, otherwise, " failure " is labeled as by steps all before, and calls algorithm 12, by intermediate chain 1 (ICC1) known together with participating in chain 1 (PPC1) and participating in chain 2 (PPC2), decide whether to cancel intermediate chain 1 (ICC1) with participating in The transaction undetermined of chain 1 (PPC1), and return to error message；If algorithm (b), then intermediate chain 1 (ICC1) informs participation chain 1 (PPC1) current stateful transaction, as process (2a), while the process (2) entered in row mode (I)；

(9) participate in chain 2 (PPC2) and inform whether current participation chain 2 (PPC2) agrees to the transaction to intermediate chain 1 (ICC1), such as Fruit agrees to that then sending participation chain 2 (PPC2) to intermediate chain 1 (ICC1) proves that the information of the transaction can be carried out, for intermediate chain 1 (ICC1) verify, as process (3)；

(10) intermediate chain 1 (ICC1) is verified to the information, if the verification passes, then into (12) step, otherwise will All steps are labeled as " failure " before, and call algorithm 12, by intermediate chain 1 (ICC1) with participating in chain 1 (PPC1) and participating in chain 2 (PPC2) known together, decide whether to cancel intermediate chain 1 (ICC1) and participate in the transaction undetermined of chain 1 (PPC1), and return to mistake Information；

(11) intermediate chain 1 (ICC1) is to participate in chain 2 (PPC2) to inform whether the transaction meets transaction to chain 1 (PPC1) is participated in Condition, if can perform, as process (4a) and process (4b)；

(12) if within certain time (Time1), participating in chain 1 (PPC1) and failing to receive the notice that transaction can be performed, then Intermediate chain (ICC1) is known together with participating in chain 1 (PPC1) and participating in chain 2 (PPC2), decides whether to cancel the transaction, if it is, Then enter (13) step, otherwise into (14) step；

(13) steps all before is labeled as " failure ", and cancels intermediate chain (ICC1) with participating in chain 1 (PPC1) Transaction undetermined, and cancel intermediate chain (ICC1) with participate in chain 2 (PPC2) transaction undetermined, subsequent intermediate chain 1 (ICC1) again with Participate in chain 1 (PPC1) and participation chain 2 (PPC2) is known together, and return to failure information；
