Embodiment two

The embodiment of the present invention two provides a kind of specific network trading method based on block catenary system.For the ease of reason Solution, block catenary system involved in the embodiment of the present invention two is introduced first below：

Fig. 1 shows the integrated stand composition of block catenary system.As shown in figure 1, block catenary system includes successively from top to bottom： User, transacting customer end, block chain service layer, block chain core layer and message network node.Wherein, user is primarily referred to as Need the domestic consumer being traded；Transacting customer end refers mainly to the client for being used to pay that all kinds of payment platforms are provided；Area Kuai Lian service layers are used to provide the interface for accessing block chain core layer, in order to which user accesses；Block chain core layer includes having One group of block chain network node of hierarchical relationship, for realizing the Core Feature in the present invention；Message network node is used to connect Each block chain network node in block chain core layer, in order to being in communication with each other between each block chain network node.Its In, improved present invention is generally directed to block chain core layer.In addition, message network node is optional, the present invention its In block catenary system involved by his embodiment, message network node can also be omitted, by each block chain network node it Between direct communication.

Fig. 2 a show the block chain core in a kind of block catenary system for concrete form that the embodiment of the present invention two is related to The structural representation of layer, Fig. 2 b show the block in a kind of block catenary system for concrete form that the embodiment of the present invention two is related to The structural representation of chain core layer and message network node.It should be understood that the present invention both can be using shown in Fig. 2 b The system architecture that there is message network node is realized, it would however also be possible to employ the system architecture without message network node shown in Fig. 2 a Realize.In follow-up embodiment, illustrated by taking the system architecture shown in Fig. 2 b as an example, in Fig. 3 a- Fig. 3 b and In Fig. 5, it is also the presence of message network node to eliminate in message network node, but actual figure 3 above a- Fig. 3 b and Fig. 5.

As shown in Fig. 2 the block catenary system includes the block chain network node of multiple levels, wherein, the plurality of level Block chain network node include it is following at least two：First level block chain network node, it is under the jurisdiction of the first level block Second level block chain network node of chain network node, the third layer level block for being under the jurisdiction of the second level block chain network node Chain network node ... until being under the jurisdiction of the n-th layer level block chain network node of N-1 level block chain network nodes；Its In, N is the natural number more than three.Wherein, the block chain network node of the plurality of level include it is following at least two contain Justice refers to：The block chain network node of the plurality of level at least includes two levels in text in each level for mentioning.For example, The first level block chain network node only can be included and be under the jurisdiction of the second level area of the first level block chain network node Block chain network node.

The present invention is to the block chain network node that is included in the level quantity and each level of block chain network node Quantity is not limited.For example, the block chain network node of the plurality of level is specifically included：At least one first level block link network It is network node, multiple the second level block chain network nodes for being under the jurisdiction of each the first level block chain network node respectively, multiple Be under the jurisdiction of respectively each the second level block chain network node third layer level block chain network node ... until multiple points It is not under the jurisdiction of the n-th layer level block chain network node of each N-1 level block chain network node；Wherein, N is oneself more than three So count.

For example, in a specific example, the block chain network node of the plurality of level is specifically included：One the first level Block chain network node 0, three be under the jurisdiction of the first level block chain network node 0 respectively the second level block chain network node 00th, 01 and 02, in addition, also including three third layer for being under the jurisdiction of the second level block chain network node 00 respectively level block link networks Network node 000,001 and 002, and two third layer level block chains for being under the jurisdiction of the second level block chain network node 01 respectively Network node 010 and 011, and three third layer level block chains for being under the jurisdiction of the second level block chain network node 02 respectively Network node 020,021 and 022.Wherein, the level dividing mode of the block chain network node of multiple levels shown in Fig. 2 is only Schematically, those skilled in the art can also flexibly use the level dividing mode of other forms.For example, the first level block The quantity of chain network node can also be two or more, the quantity of the second level block chain network node and be subordinate to respectively Can flexibly it be set in the quantity of the third layer level block chain network node of each second level block chain network node, and And, those skilled in the art can also set more hierarchical relationships.The node that specific level quantity and each level are included Quantity can flexibly be determined according to actual business scenario.

Preferably, each block chain network node has corresponding higher level's block chain network node and/or subordinate's block chain Network node；Wherein, the quantity of the corresponding higher level's block chain network node of each block chain network node (certainly, exists for one The quantity of some in particular cases corresponding higher level's block chain network nodes of each block chain network node can also be multiple), Each the quantity of the corresponding subordinate's block chain network node of block chain network node is one or more.For example, the first level area Block chain network node 0 has three subordinate's block chain network nodes (i.e.：Second level block chain network node 00,01 and 02), Third layer level block chain network node 000 has higher level's block chain network node (i.e.：Second level block chain network node 00)。

Wherein, each block chain network node is under the jurisdiction of the superior node of the block chain network node, each block link network The downstream site of network node is under the jurisdiction of the block chain network node.Wherein, block chain network node A is under the jurisdiction of block chain network section Point B implication refers to：Block chain network node A with and be only connected with block chain network node B, also, block chain network node A For block chain network node B downstream site.As can be seen here, each block chain network node with and the block that is only subordinate to it Chain network node is joined directly together, and is not joined directly together then with other block chain network nodes.For example, third layer level block link network Network node 000 only with its higher level's block chain network node (i.e.：Second level block chain network node 00) it is joined directly together, and and its His block chain network node is not joined directly together then.

Under normal circumstances, the quantity of higher level's block chain network node is more than the quantity of subordinate's block chain network node.For example, In a kind of example, the quantity of the first level block chain network node is 1, and the quantity of the second level block chain network node is N2, the quantity of third layer level block chain network node is N3, and the quantity of N-1 level block chain network nodes is N-1, the The quantity of N level block chain network nodes is N.Wherein, N>N-1>N3>N2>1.Net is advantageously implemented by this kind of set-up mode Stratified management between network node.Certainly, in other embodiments of the invention, it is also possible to subordinate's block chain network section occur Point quantity is less than the situation of higher level's block chain network number of nodes, in a word, and the present invention does not limit the area that each level is included The particular number of block chain network node.The block chain network number of nodes that each level is included can be one or It is multiple.

The core of the dividing mode of multi-layer in above-mentioned block catenary system is following two aspect：On the one hand, by block Chain carries out laterally point chain, and so-called transverse direction point chain refers to：The block link network of multiple same levels can be included in same level Between network node, the block chain network node of these same levels each other the brotgher of node (for example third layer level block chain network section The brotgher of node each other of point 010 and 011).By laterally point chain by all transaction be divided into multi-layer block chain network node it Between chain in transaction and across chain transaction, allow the transaction of all different blocks chain network nodes parallel, so as to greatly improve whole The performance of individual block catenary system.On the other hand, block chain is carried out it is longitudinal layered, it is so-called longitudinal layered to refer to：Will be all Block chain network node is divided into multiple different levels from top to bottom.By the way that block chain can be divided into block chain is longitudinal layered Multigroup block chain of different levels, the transaction after collecting is submitted to upper strata by the block chain of lower floor, while realizing some levels Transaction between account.As can be seen here, by laterally point chain and it is longitudinal layered can lift the flexibility of block catenary system, be many The concurrently execution of transaction provides safeguard.

Common recognition operation and book keeping operation operation are carried out for the ease of each block chain network node disjoint, in above-mentioned multiple levels Block chain network node in each block chain network node further comprise：Know together child node, for for the block The related network trading of chain network node generates corresponding Transaction Information；Account book child node, for according to the block chain network section The Transaction Information of common recognition child node generation in point is kept accounts.In addition, in each block chain network node, will can also be somebody's turn to do A child node in block chain network node is set to be provided simultaneously with the node of common recognition child node and account book child node function. That is, common recognition child node and account book child node in each block chain network node can both be saved by two independent sons respectively Point is realized, can also be integrated in same child node, is realized by a child node, so as to simplify the structure of network node.Its In, the network trading related to the block chain network node includes at least one of following：Occur in the block chain network section Merchandised in chain inside point, and occur across the chain friendship between the block chain network node and other block chain network nodes Easily；Wherein, across chain transaction further comprises：With across the chain transaction of level and across the chain transaction of cross-layer level.As can be seen here, with it is traditional Different (the All Activities in traditional block catenary system of mode that one unified common recognition operation entry is only provided in block catenary system Common recognition operation must all be realized via the unified common recognition operation entry, thus can not concurrently perform multiple transaction), the present invention In mode (be respectively provided with equivalent to there is provided multiple common recognition operation entries that can be used parallel in each block chain network node One is capable of the entrance that complete independently common recognition is operated), and each block chain network node is handed over only for relative network Easily known together, other block chain network nodes unrelated with the transaction are not involved in the common recognition operation of the transaction, accordingly, it is capable to Enough common recognition operations for concurrently carrying out multiple transaction, had both improved the concurrency of system, the time delay of common recognition operation are reduced again.And And, it is different from the mode that one big account book is only provided in traditional block catenary system that (traditional block catenary system is big by one Account book records each transaction between all block chain network nodes), the present invention in mode equivalent to there is provided multiple independences Small account book (be respectively provided with each block chain network node one be capable of complete independently book keeping operation operation account book child node), and And, the account book in each block chain network node need to only record the transaction account related to the block chain network node, nothing The transaction account unrelated with the block chain network node need to be recorded, so as to improve the efficiency of book keeping operation and inquiry.

In addition, being in communication with each other for the ease of multiple block chain network nodes between each level, also further set in Fig. 2 b Four news network units, respectively news network unit 1, news network unit 2, news network unit 3 and news network Unit 4.Wherein, each message network node and the block chain network node of each level are respectively connected with, for forwarding each layer Transaction Information between the block chain network node of level.When implementing, each message network node respectively with multiple block chains Network node is connected, and is respectively connected between multiple message network nodes；Wherein, each message network node specifically for：Connect The Transaction Information from coupled block chain network node or other message network nodes is received, obtains and is included in Transaction Information Purpose block chain network node identification, Transaction Information is forwarded according to purpose block chain network node identification.Specifically, Each message network node can be realized by news network middleware, in addition, can be preserved in each message network node A connection table, the connection table be used for store the annexation between each message network node and other message network nodes with And the annexation between each block chain network node and each message network node, in order to which message network node is according to this Connection table is that the communication information received determines optimal forward-path.Wherein, the communication information of message network node forwarding includes But Transaction Information is not limited to, other various types of messages are can also be.Optimal forward-path can using shortest path first or its He is selected all kinds of routing algorithms.In addition, for the ease of safeguarding the connection table, each block chain network node with certain message After network node is set up or disconnected, set up message to the connection accordingly of other block chain network node broadcasts or connection is disconnected Message is opened, in order to which other block chain network nodes and message network node set up message or connection according to the connection received The disconnection information updating connection table.In addition, the particular number of news network unit can flexibly be set, for example it can also be provided that It is one or more.Moreover, the connected mode between each news network unit can also flexibly be set：For example, small-sized In block catenary system, each news network unit can be respectively connected with other all news network units, in order to fast Speed forwarding message；In large-scale block catenary system, each news network unit can only with a part of news network unit phase Even, so as to realize the forwarding of message by the relaying of multiple news network units.Specific number of the present invention to message NE Amount and type of attachment are not limited.

Inventor has found during the present invention is realized：In traditional block catenary system for not using news network unit In, if two block chain network nodes not being joined directly together need mutually forwarding message, such as third layer level block chain network section Point 010 is intended to forward message to third layer level block chain network node 022, and first, third layer level block chain network node 010 needs The child list corresponding to third layer level block chain network node 022 is obtained, then, third layer level block chain network node All child nodes in 010 will be set up with all child nodes in third layer level block chain network node 022 respectively to be connected.Thus A series of defects such as cause cumbersome, efficiency of transmission low.Therefore, in order to solve the above problems, the present invention is in block linkwork In system be provided with least one above-mentioned news network unit, correspondingly, in each block chain network node can respectively include with Each child node in the connected news network interface of at least one message network node, the block chain network node is disappeared by this Breath network interface can be set up with news network unit and communicate, and then be realized and any block chain network by news network unit Communication between node.At least possesses following advantage using news network unit：On the one hand, news network unit can quickly just Connect each block chain network node promptly, therefore, either the block chain network node of same level or different levels it Between can pass through news network unit and transmit message, it is to avoid two block chain network nodes not being joined directly together are pre-established The troublesome operation of connection；On the other hand, for some special application scenarios, some of same block catenary system block It is not allow directly to set up communication connection (such as in order to improve internet security, different departments of banking between chain network node Do not allow directly to set up communication connection between system), therefore, communication link can not can also directly set up by news network unit Realize that message is transmitted between the block chain network node connect.Sum it up, using news network unit, large-scale block can be lifted Network consumption and time delay during the common recognition ability of catenary system, reduction common recognition, improve the disposal ability of whole system, also, Block catenary system is deployed in can not be under the scene of point-to-point interconnection.

In order to make it easy to understand, next, the treatable type of transaction of block catenary system institute is discussed in detail.Carried in the present invention In the block catenary system of confession, network trading is divided into two major classes：

First major class network trading is to be merchandised in chain, and transaction refers in so-called chain：Occur in a block chain network node One internal or many network tradings.For example, Fig. 3 a show the both parties of transaction in a chain, in fig. 3 a, the 3rd Level block chain network node 000 corresponds to two different clients, and the account address of the first client is add1, the second visitor The account address at family end is add2.Because the two clients are all under the jurisdiction of third layer level block chain network node 000, therefore, The transaction is not directed to other block chain network nodes, has related only to a block chain network node, therefore, the pen Merchandise to merchandise in chain.

Second major class network trading is across chain transaction, and so-called across chain transaction refers to：Occur at least two different blocks One between chain network node or many network tradings.Wherein, across chain transaction can be further divided into again：With level across chain Transaction is (i.e.：The corresponding block chain network node of both parties belongs to same level) and across the chain transaction of cross-layer level is (i.e.：Transaction is double The corresponding block chain network node in side belongs to different levels).For example, Fig. 3 b show a transaction merchandised with level across chain Both sides, in fig 3b, third layer level block chain network node 010 correspond to the 3rd client that account address is add3, the 3rd Level block chain network node 020 corresponds to the 4th client that account address is add4.Because the two clients belong to respectively In two different block chain network nodes (i.e.：The transaction is related at least two block chain network nodes), and two not Same block chain network node belongs to the second level (i.e.：Two different block chain network nodes brotgher of node each other), because This, the transaction is with across the chain transaction of level.And for example, Fig. 3 c show the both parties that a cross-layer level is merchandised across chain, in figure In 3c, third layer level block chain network node 022 corresponds to the 5th client that account address is add5, the second level block chain Network node 02 corresponds to the 6th client that account address is add6.Due to the two clients be belonging respectively to two it is different Block chain network node, and two different block chain network nodes are not belonging to same level, therefore, the transaction is cross-layer level Across chain transaction.

For the ease of understanding above-mentioned all kinds of transaction, Fig. 4 shows each that a block chain network intra-node includes The schematic diagram of child node (each child node is it can be appreciated that a module).As shown in figure 4, in each block chain network node Portion is further included：Trade management child node 41, common recognition child node 42, network interface 43, block management child node 44, account in chain This child node 45, news network interface 46 and across chain transaction collect child node 47.Wherein, the child node division side shown in Fig. 4 Formula is only schematical, and those skilled in the art can also merge to other multiple child nodes, or by a certain child node More child nodes are split as, the present invention is not limited this.Wherein, news network interface 46 and across chain transaction collect sub- section Point 47 is mainly used in realizing across chain transaction, and news network can also be omitted in the block chain network node for being only used for merchandising in chain Interface 46 and across chain transaction collect child node 47.

First, the particular transactions flow merchandised in the chain shown in Fig. 3 a is introduced with reference to Fig. 4：First client is connect by service Mouth layer reports a network trading for including transaction id, and service interface layer judges the block chain network corresponding to the first client Node is third layer level block chain network node 000 (for example being determined according to the address of opening an account of client), so that by this network Transaction is submitted in the trade management child node 41 included in third layer level block chain network node 000.Wherein, service interface layer It is respectively connected with the block chain network node of multiple levels, block chain network node and visitor for receiving and forwarding multiple levels Communication information between the end of family, for example, service interface layer can be realized by the block chain service layer in Fig. 1.The trade management (such as checking account balance whether abundance) is verified in 41 pairs of transactions of child node, proposes the transaction after being verified Give the common recognition child node 42 included in third layer level block chain network node 000.The common recognition child node 42 passes through network in chain Other each child nodes that interface 43 is obtained in third layer level block chain network node 000 are sent out after reaching common understanding for the transaction The notification message sent, and accordingly generate corresponding Transaction Information.It can include what is confirmed through each child node in the Transaction Information Transaction List Table.Then, the Transaction Information is submitted to block management module 44 by common recognition child node.Responsible pair of block management module 44 Successful transaction queue of knowing together carries out block packing processing, so as to which the block after packing is write into third layer level block chain network section In the account book child node 45 included in point 000.As can be seen here, in the chain that the present invention is provided in transaction flow, only by transaction phase The block chain network node of pass completes common recognition, book keeping operation operation, and other block chain network nodes unrelated with transaction are without participating in altogether Knowledge, accounting procedure, so as to simplify the complexity of common recognition operation, reduce processing delay, also, account of merchandising is recorded only in phase In the account book of the block chain network node of pass, book keeping operation is participated in without other unrelated block chain network nodes, opening for book keeping operation is simplified Pin, facilitates inquiry.

Next, introducing the transaction flow merchandised across chain shown in Fig. 3 b with reference to Fig. 4：3rd client passes through service interface Layer reports across a chain network transaction for including transaction id, and service interface layer judges the block link network corresponding to the 3rd client Network node is third layer level block chain network node 010, so that across the chain network transaction of the pen is submitted into third layer level block chain In the trade management child node included in network node 010.The trade management child node is verified to across the chain transaction of the pen, is tested Card submits to this across chain transaction the common recognition child node included in third layer level block chain network node 010 after passing through.This is total to Child node is known by other each child nodes in network interface acquisition third layer level block chain network node 010 in chain for being somebody's turn to do The notification message that across the chain transaction of pen is sent after reaching common understanding, and accordingly generate corresponding first Transaction Information.The first transaction letter The transaction List Table confirmed through each child node can be included in breath.Then, the common recognition child node is further used for：It is determined that with the pen Other related block chain network nodes of across chain transaction.For example, in this example, another counterparty merchandised according to this across chain The account address add4 of four clients determines that other block chain network nodes related to across the chain transaction of this are third layer level area Block chain network node 020.Specifically, other block chain network nodes related to across the chain transaction of this refer to：In the pen across chain In block chain network node corresponding to the involved counterparty of transaction, except the block chain network section where current common recognition child node Block chain network node outside point, the quantity of other the block chain network nodes related to across the chain transaction of this is usually one Individual, when there is many lineal transactions, the quantity of other the block chain network nodes related to across the chain transaction of this can also be It is multiple.Then, the common recognition child node is further used for：The first Transaction Information generated for across the chain transaction is transmitted to being somebody's turn to do Other related block chain network nodes of across chain transaction；Also, receive other block chain network sections related to being somebody's turn to do across chain transaction Second Transaction Information of the point for across the chain transaction generation.For example, in this example, in third layer level block chain network node 010 Comprising common recognition child node need the first Transaction Information being sent to third layer level block chain network node 020, and further connect Receive second Transaction Information of the third layer level block chain network node 020 for across the chain transaction generation.Finally, third layer level block First Transaction Information and the second Transaction Information are submitted to third layer level by the common recognition child node included in chain network node 010 The block management module 44 included in block chain network node 010.The block included in third layer level block chain network node 010 Management module 44 is responsible for carrying out block packing processing to successful transaction queue of knowing together, so as to third layer level block chain network node The account book child node included in 010 can write the block after packing what is included in third layer level block chain network node 010 In account book.Specifically, the account book child node in third layer level block chain network node 010 specifically for：Believed according to the first transaction Breath and the second Transaction Information are kept accounts to across the chain transaction.

Wherein, the first above-mentioned Transaction Information and the second Transaction Information can be by each block chain network nodes News network interface and message network node are forwarded.For example, the first Transaction Information passes through third layer level block chain network News network interface in node 010 is sent to the 3rd message network node, and the 3rd message network node is believed according to the first transaction The purpose block chain network node identification included in breath, the second message is passed through using shortest path first by first Transaction Information Target node is to third layer level block chain network node 020.In addition, the second above-mentioned Transaction Information can also be omitted, only Known together according to the first Transaction Information, moreover, the concrete form and the content present invention of Transaction Information are not construed as limiting, as long as can Realize the purpose of joint common recognition.

As can be seen here, during being merchandised across chain, the involved corresponding area of All Activity side of across the chain transaction of this Block chain network node, which needs to combine, participates in common recognition and accounting procedure.Wherein, the involved All Activity side of across the chain transaction of this Quantity be usually two, may also be multiple in some lineal transactions.Correspondingly, the related block chain of across the chain transaction of this The quantity at least two of network node, every block chain network node related to across the chain transaction of this be both needed to participate in common recognition and Accounting procedure.Therefore, the either block chain network node related to across the chain transaction of this, need to be by itself after generation Transaction Information The Transaction Information of generation is sent to other block chain network nodes related to across the chain transaction of this, for across the chain transaction of the pen Related other block chain network nodes joint common recognition and book keeping operation；Meanwhile, the either block link network related to across the chain transaction of this Network node will also further receive other the block chain network nodes life related to across the chain transaction of this after generation Transaction Information Into Transaction Information, so as to the Transaction Information progress according to related to this across chain transaction other block chain network nodes generation Joint common recognition and book keeping operation.That is, across a chain transaction only reaches in the block chain network node corresponding to Trading parties Just finally it can come into force and keep accounts after into common recognition.

In addition, the book keeping operation mode that the present invention is directed in across chain transaction has also carried out following improvement：In order to simplify higher level's block Account book data volume in chain network node, the present invention has carried out collecting operation further directed to across chain transaction.Specifically, in order to just Collect the particular content of operation in understanding, the two class accounts included in the system that the present invention is provided are introduced first：

For each block chain network node, the block chain network node corresponds to a first kind account address, For identifying the account corresponding to the block chain network node.The first kind account address is usually publicly-owned account address, also may be used To be interpreted as the account of each block chain network node, it belongs to block chain, is controlled by knowing together algorithm, under conventional scenario by Block chain collects assets in generation, account to transaction to be directly traded.For example, it is assumed that a block chain network node generation One bank of table, then first kind account address is the total account of the bank.

Each block chain network node also corresponds to multiple Equations of The Second Kind account addresses, wherein, multiple Equations of The Second Kind account addresses It is under the jurisdiction of the corresponding first kind account address of block chain network node, and each Equations of The Second Kind account address is respectively used to mark and is somebody's turn to do The account corresponding to client or subordinate's block chain network node corresponding to block chain network node.The Equations of The Second Kind account address Usually privately owned account address, it is understood that be the client or subordinate's block chain network of each block chain network node subordinate The account of node, it belongs to user, is controlled by key, and user can be operated by key to the assets in account.On The account address for stating two class accounts can be by " chain ID:The form composition of address in chain ", wherein, chain ID represents the ownership of the chain ID。

Fig. 5 shows the schematic diagram for collecting transaction between above-mentioned two classes account.As shown in figure 5, for the second level area For block chain network node 00, the corresponding first kind account address of the second level block chain network node 00 is 00:Pub, and And, the second level block chain network node 00 also corresponds to three Equations of The Second Kind account addresses, i.e.,：Third layer level block chain network The account address 000 of node 000:Pub, third layer level block chain network node 001 account address 001:Pub and the 3rd The account address 002 of level block chain network node 002:Pub, the corresponding first kind account of the second level block chain network node 01 Family address is 01:pub.Similarly, for third layer level block chain network node 000, third layer level block chain network section 000 corresponding first kind account address of point is 000:Pub, also, third layer level block chain network node 000 also corresponds to four Individual Equations of The Second Kind account address, i.e.,：The account address 000 of first client:Add1, the second client account address 000: Add2, the 3rd client account address 000:Add3 and the 4th client account address 000:add4.On others The first kind account address of block chain network node is similar with Equations of The Second Kind account address principle, and here is omitted.As can be seen here, First kind account address is the account address of corresponding block chain network node in itself, and Equations of The Second Kind account address is corresponding block The client of chain network node subordinate or the account address of subordinate's block chain network node.Therefore, a specific account address, It is directed to for different block chain network nodes, different types may be belonged to.For example, for the second level block chain network For node 00, the account address " 000 of third layer level block chain network node 000:Pub " is Equations of The Second Kind account address, specifically Reason is：Third layer level block chain network node is the downstream site for being subordinated to the second level block chain network node；However, For third layer level block chain network node 000 itself, the account address of third layer level block chain network node 000 “000:The first kind account addresses of pub " then for third layer level block chain network node 000, concrete reason is：The account Address is the address of third layer level block chain network node in itself.

With reference to two above-mentioned class account addresses, improvement of across the chain transaction in terms of book keeping operation during description is of the invention：Across In chain transaction flow, across the chain transaction included in each block chain network node collect child node specifically for：Extract and the area Across the chain transaction included in the related network trading of block chain network node；It is determined that the corresponding Equations of The Second Kind of across chain exchange extracted The first kind account address that account address and each Equations of The Second Kind account address are subordinate to；To with being under the jurisdiction of identical first kind account Across chain transaction corresponding to the Equations of The Second Kind account address of location is merged, between each first kind account address after being merged Transaction record.Wherein, the quantity of the corresponding Equations of The Second Kind account address of across chain exchange extracted is generally at least two, phase Ground is answered, it is necessary to determine the first kind account address that each Equations of The Second Kind account address is subordinate to respectively.In addition, to being under the jurisdiction of identical Across chain transaction corresponding to the Equations of The Second Kind account address of one class account address, which is merged, to be typically referred to：For two or more pens For across chain transaction, if the first kind account address difference phase that each Equations of The Second Kind account address corresponding to per transaction is subordinate to Together, then it can merge.Wherein, across chain transaction, which collects child node, to collect operation for across the chain transaction progress of each pen respectively, Can also at every predetermined time the cycle collect operation for across the chain transaction progress that occurs in this cycle, it is of the invention that this is not done Limit.

Specifically, in Figure 5, third layer level block chain network node 000 and third layer level block chain network node 010 it Between there occurs four across chain transaction, be across the chain transaction of the first stroke that transaction id is 1, second across chain friendship that transaction id is 2 respectively Easily, the 3rd across the chain transaction that transaction id is 3 and the 4th across the chain transaction that transaction id is 4.Transaction id is used for unique mark One across chain transaction.Wherein, across the chain transaction of each pen has the first counterparty and the second counterparty, and usual first counterparty is money The gold side of producing, the second counterparty is the fund side of being transferred to, it is of course also possible to which the first counterparty is the fund side of being transferred to, the second counterparty For the fund side of producing, the present invention is not limited this.Moreover, in lineal transaction, the number of the first counterparty and the second counterparty Amount may be multiple.Specific in this example, account address (i.e. above-mentioned of the first counterparty in this four across chain transaction Two class account addresses) it is respectively 000:add1、000:add2、000:Add3 and 000:Add4, i.e.,：First transaction of each transaction Fang Jun is under the jurisdiction of same block chain network node (i.e.：Third layer level block chain network node 000)；The account of second counterparty Address is respectively 010:add5、010:add6、010:Add7 and 010:Add8, i.e.,：Second counterparty of each transaction is subordinate to In same block chain network node (i.e. third layer level block chain network node 010).Therefore, the first transaction in each transaction The first kind account address that Equations of The Second Kind account address corresponding to side is subordinate to is identical, and the second counterparty institute in each transaction The Equations of The Second Kind account address that corresponding Equations of The Second Kind account address is subordinate to is also identical, therefore, it can be directed to this four across chain transaction Merge, obtain the transaction record between each first kind account address after a merging.Wherein, after merging each At least one of the following is included in transaction record between one class account address：Each first kind account address after merging it Between transaction total amount, and the transaction ID merchandised across chain of each pen before merging.For example, it is assumed that four above-mentioned across chain transaction Transaction content be respectively first the second counterparty of transaction direction pay 10 yuan, 20 yuan, 30 yuan and 20 yuan, correspondingly, after merging The transaction content included in transaction record between each first kind account address of one obtained is as follows：Total amount of merchandising is 80 Member, and the first counterparty after merging be subordinate to by the corresponding Equations of The Second Kind account address of each first counterparty before merging the One class account address is (i.e.：The account address 000 of third layer level block chain network node 000:pub)；The second transaction after merging The first kind account address that the square corresponding Equations of The Second Kind account address of each second counterparty for before merging is subordinate to is (i.e.：3rd The account address 010 of level block chain network node 010:pub)；Also, for the ease of tracing to the source, the pen obtained after merging is each Further comprised in transaction record between individual first kind account address merge before four across chain merchandise transaction ids 1,2, 3rd, 4, the details of each transaction of quick search are capable of according to transaction id.

In addition, entering for the ease of realizing that across the chain transaction in multi-zone supervision, each block chain network node collects child node One step is used for：Transaction record between each first kind account address after merging is supplied in the block chain network node Account book child node；And the account book child node in each block chain network node is further used for：By each first kind after merging Transaction record between account address is supplied to higher level's block chain network node corresponding to the block chain network node, by the area The account book child node in higher level's block chain network node corresponding to block chain network node is kept accounts；And/or, receive the block Each first kind account after the merging that account book child node in subordinate's block chain network node corresponding to chain network node is provided Transaction record between the address of family is simultaneously kept accounts.As can be seen here, the account book in each block chain network node is only to direct It is under the jurisdiction of the Transaction Details of every transaction between the client of the block chain network node and/or subordinate's block chain network node Recorded, and for being under the jurisdiction of indirectly between the client and/or subordinate's block chain network node of the block chain network node Every transaction, then do not record specific Transaction Details, and only record the subordinate by being directly under the jurisdiction of the block chain network node Block chain network node collects the transaction record obtained after merging.By this kind of mode, the stratified management of account book is realized, by The details of each penny ante between the management organization in upper strata is often not relevant for underlying user, and be only concerned about directly It is under the jurisdiction of the transaction record of the Lower Establishment of the management organization, therefore this kind of mode more conforms to actual regulatory requirement.Moreover, By splitting, being classified by account book, the overhead of account book on the one hand can be simplified, it is very convenient when on the other hand being inquired about according to level Efficiently.

Certainly, for the ease of backup, prevent that account book child node in loss of data, each block chain network node can be with It is further used for：Kept accounts according to the transaction record between each first kind account address after merging.That is, each Account book child node in block chain network node is except by the transaction record between each first kind account address after merging Offer outside its superior node, also further recorded on the account book of this node.Now, in each block chain network node Account book include two parts, a part is directly under the jurisdiction of the block chain network node for each of the block chain network nodes records Client and/or downstream site Transaction Details, another part is the transaction record after collecting.

In addition, in order to more visually understand the above-mentioned intension for collecting operation, network trading can be roughly divided into two kinds, One kind is in general transaction, i.e., the chain between privately owned account or across chain transaction.One kind is to collect what transaction, i.e., many merchandised across chain If participant in same block chain, can be collected as a block chain common account to the public account of block chain respectively The transaction at family, just collects transaction as one, collects the ID that transaction is converged in transaction comprising it.

The block chain network node of multiple levels in this block catenary system includes at least one of the following：Multiple levels Banking system corresponding to network node, the network node corresponding to the payment system of multiple levels.In a word, the present invention is to it Concrete application scene is not limited, in the scene that can be flexibly applied to all kinds of differentiated control.

Based on above-mentioned block catenary system, the embodiment of the present invention two provides a kind of network trading method.The network trading Involved transaction is primarily referred to as across chain transaction mentioned above in method, both can be across the chain transaction of same level or Across the chain transaction of cross-layer level.In addition, it will be appreciated to those of skill in the art that network trading that the embodiment of the present invention two is provided Method can also be applied to the area of other various improvement or variant in addition to it can be applied to above-mentioned block catenary system In block catenary system, as long as including the block chain network node of multiple levels in block catenary system, in order to realize each block Independent common recognition and book keeping operation between chain network node.

Fig. 6 shows the flow chart for the network trading method that the embodiment of the present invention two is provided.As shown in fig. 6, this method Comprise the following steps：

First, before this method execution, sent altogether from the first block chain network node to the second block chain network node Know and initiate message.When the second block chain network node is multiple, it is necessary to be sent respectively to each second block chain network node The common recognition initiates message.Specifically, the first block chain network node determines the whole block link networks related to this network trading Network node, other block chain network nodes in whole block chain network nodes in addition to the first block chain network node are determined For the second block chain network node；First block chain network node sends common recognition hair respectively to each the second block chain network node Message is played, initiate message according to common recognition for each the second block chain network node constitutes interim with the first block chain network node Common recognition network.Wherein, each block chain network node of the network internal of knowing together temporarily respectively with the interim common recognition network internal Other block chain network nodes be connected；Wherein, the quantity of the second block chain network node is one or more.For the ease of structure Interim common recognition network is built, above-mentioned common recognition initiates that in message each block chain network section related to this network trading can be included The mark of point, in order to set up connection between each block chain network node.In addition, above-mentioned interim common recognition network is further wrapped The message network node for being used to connect each block chain network node containing at least one.Setting on message network node can be joined Examine described above, here is omitted.

For the ease of understanding said process, the network trading in the present invention is simply introduced first below：One net Network transaction includes the first counterparty realized by the first block chain network node and by the realization of the second block chain network node Second counterparty.Wherein, the first counterparty and the second counterparty can be respectively the fund side of producing and the fund side of being transferred to, can also Respectively the fund side of being transferred to and the fund side of producing.In addition, can as the quantity of the first block chain network node of the first counterparty Think one or more, can also be one or more as the quantity of the second block chain network node of the second counterparty.Always It, the first block chain network node and the second block chain network node cover the whole block chains related to this network trading Network node.Specifically, can be by all block chain networks related to this network trading for a network trading Either block chain network node in node is used as the first block chain network node (the i.e. first transaction in this network trading Side), by other in whole block chain network nodes related to this network trading in addition to the first block chain network node Block chain network node is collectively as the second block chain network node.For example, it is assumed that a network trading is：By block chain network Node A is transferred to a certain amount of fund respectively to block chain network node B, C, then can be used as the pen by block chain network node A The first block chain network node in network trading, by block chain network node B, C collectively as in this network trading Two block chain network nodes；Or, the first block link network in this network trading can also be used as by block chain network node B Network node, by block chain network node A, C collectively as the second block chain network node in this network trading.The present invention is right This is not limited.

In a word, for a specific transaction, the first block chain network node and the second block chain network node are common With the whole block chain network nodes related to this network trading are constituted, in addition, it is generally the case that with this network trading phase Whole block chain network nodes of pass are the Partial Block chain network node in whole block catenary system, rather than whole block chain Whole block chain network nodes in system, that is to say, that in whole block catenary system, except the first block chain network node and the Outside two block chain network nodes, the 3rd block chain network node is at least also included, the 3rd block chain network node refers to：With this Unrelated whole block chain network nodes of network trading, its quantity is usually multiple.3rd block chain network node is obvious not Included in above-mentioned interim common recognition network.

In addition, for a network trading, can the preferred fund side of the producing active hair by this network trading Serve the common recognition stated and initiate message, or, above-mentioned be total to can also actively be sent by the fund side of being transferred in this network trading Know and initiate message, can also be operated as each spontaneous carry out common recognition of block chain network node involved by this network trading. Therefore, the operating procedure for sending above-mentioned common recognition initiation message for the network trading by the first block chain network node is optional , when being operated by the spontaneous progress common recognition of each block chain network node, the operating procedure can also be omitted.

Step S610：First block chain network node generates corresponding Transaction Information for the network trading.

Wherein, the first block chain network node is as the first counterparty in network trading, in being block catenary system Any node.For example, in this example, the first block chain network node is the third layer in across chain transaction flow mentioned above Level block chain network node 010, its detailed process for generating corresponding first Transaction Information can refer to corresponding description above, Here is omitted.For example, the first block chain network section can be confirmed by the common recognition child node in the first block chain network node Whether each child node included in point reaches common understanding to network trading, if so, then being handed over for network trading generation is corresponding Easy information.In addition, Transaction Information can be various forms of information, all kinds of contents related to the network trading can be included, The present invention is not construed as limiting to the concrete form and particular content of Transaction Information.The Transaction Information is mainly used in being supplied to the second block Chain network node, so that the second block chain network node is combined for this network trading with the first block chain network node Common recognition.Therefore, as long as the information content for being implemented for joint common recognition can be as Transaction Information.For example, at one In the Transaction Information of network trading, the node identification comprising Trading parties, and type of transaction and dealing money.Wherein, merchandise The node identification of each side is used for the identity for confirming transaction participant, and type of transaction can be from the first block chain network node to the Two block chain network nodes are transferred accounts, or are transferred accounts from the second block chain network node to the first block chain network node.In a word, Two block chain network nodes are able to verify that the validity of this network trading by Transaction Information, so as to realize joint common recognition mesh 's.

Step S620：Transaction Information is sent to the second block chain network section as the second counterparty in network trading Point.

Wherein, the second block chain network node is used as the second counterparty in network trading or block catenary system In any node.For example, in this example, the second block chain network node is the 3 in across chain transaction flow mentioned above Level block chain network node 020.

Specifically, the first block chain network node is determined as the second block of the second counterparty in network trading first The mark of chain network node, is then sent to the second block chain network node according to the mark by Transaction Information.When implementing, In order to improve communication efficiency, it can will be merchandised and believed by least one message network node included in above-mentioned interim common recognition network Breath is sent to the second block chain network node as the second counterparty in network trading；Wherein, at least one news network Node and the block chain network node of each level are respectively connected with, between the block chain network node for forwarding each level Transaction Information.Specific set-up mode and its advantage on message network node can refer to described above, and here is omitted.

Step S630：First block chain network node and the second block chain network node are believed the transaction using common recognition algorithm Breath is reached an agreement.

Specifically, the first block chain network node and the second block chain network node can pass through above-mentioned interim common recognition net Network, is reached an agreement using common recognition algorithm to Transaction Information.Wherein, the first block chain network node and the second block chain network node Flexibly it can determine whether to reach an agreement to above-mentioned Transaction Information using all kinds of common recognition algorithms, if so, then continuing executing with step S640。

Step S640：First block chain network node and the second block chain network node are to the Transaction Information pair reached an agreement The network trading answered synchronously is kept accounts.

Wherein, the first block chain network node records the transaction account of the network trading in the first block chain network node In, and the second block chain network node by the transaction account synchronous recording of the network trading in the second block chain network node. Specifically, the account book child node included in the first block chain network node is by the transaction of the corresponding network trading of the Transaction Information Account is recorded in the account book of the first block chain network node；The account book child node included in the second block chain network node will The transaction account of the corresponding network trading of the Transaction Information is recorded in the account book of the second block chain network node.

As can be seen here, when the first block chain network node and the second block chain network node use common recognition algorithm to the transaction When information is reached an agreement, the first block chain network node and the second block chain network node are directed to the corresponding network of the Transaction Information The synchronous book keeping operation of transaction；When the first block chain network node and the second block chain network node using common recognition algorithm to the Transaction Information When not reaching an agreement, the first block chain network node and the second block chain network node are handed over for the corresponding network of the Transaction Information Yi Jun does not keep accounts.Thus, it is possible to ensure that the first block chain network node and the second block chain network node are directed to the Transaction Information pair The accounting results for the network trading answered are consistent.

In addition, in order to ensure the account book in account book and the second block chain network node in the first block chain network node Can synchronously it keep accounts, and accounting results are consistent, and some specific processing modes can also be taken in the present invention.For example, when the After one block chain network node is kept accounts to the network trading, send and keep accounts into accordingly to the second block chain network node Work(message；After the second block chain network node is kept accounts to the network trading, sent to the first block chain network node Corresponding book keeping operation success message, each block chain network node is only receiving the book keeping operation from Correlation block chain network node After success message, just confirm to complete the final accounting procedure of the transaction, thus prevent because the various situations such as Network Abnormal are led The inconsistent situation of account book occurs on two nodes caused.Or, in order to ensure same transaction is in each related block chain Account book data in network node are consistent, can also be by each block chain network node regularly by the transaction account of each transaction The block chain network node for being sent to correlation is checked.

In addition, the accuracy in order to further lift common recognition operation, in other embodiments of the invention, the second block chain Network node can also generate Transaction Information for the network trading, and the Transaction Information of generation is supplied into the first block link network Network node verification, thereby further ensures that the accuracy of joint common recognition operation.

In addition, be to be illustrated using the quantity of the second block chain network node as one in above-mentioned steps, it is actual On, the quantity of the second block chain network node can also be multiple, correspondingly, and the first block chain network node is needed respectively to every Individual second block chain network node sends Transaction Information；And each second block chain network node can be carried out to the Transaction Information Checking.

Common recognition and accounting procedure in the present invention for network trading is achieved that by each above-mentioned step, though Right said process is only illustrated by taking a network trading as an example, but it will be appreciated to those of skill in the art that block linkwork Any one network trading in system can complete common recognition and accounting procedure by each above-mentioned step.In addition, though on The executive agent for the network trading method described in each step stated is the first block chain network node, still, due to first Block chain network node can be any node in whole block chain network nodes related to this network trading, therefore, In fact, the executive agent of the network trading method described in each above-mentioned step can be related to this network trading Any node in whole block chain network nodes, for example, it is also possible to be the second block chain network node.Moreover, when the secondth area Can be any one block chain network node therein when block chain network node is multiple.As can be seen here, in real process In, each step in each above-mentioned step is by the first block chain network node and the second block chain network node institute What each block chain network node direct interaction in the interim common recognition network of composition was completed, also, each step is by facing All block chain network nodes in Shi Gongshi networks are completed jointly.

In addition, in above process, can be according to the block chain related to the network trading for each network trading The quantity and distribution situation of network node carry out the interim common recognition network of dynamic creation one, the network of knowing together temporarily be used for connect and Each related block chain network node of the network trading, and transmission first/second is handed between each block chain network node Easy information, so that final realization carries out the mesh of joint common recognition between each block chain network node of common recognition network internal temporarily 's.As can be seen here, the present invention can be directed to each transaction dynamic creation interim common recognition network corresponding with the transaction respectively, from And the common recognition and accounting procedure of the transaction are only realized in the interim common recognition network internal, other block link networks unrelated with the transaction Network node is not included in the interim common recognition network, is also not involved in common recognition and the book keeping operation of the transaction.

As can be seen here, in the present invention common recognition and book keeping operation operation has the following characteristics that：
