Step S421, if including M business scenario in trading processing request, client asks the trading processing It asks to be divided into and be requested with the one-to-one M of M business scenario sub- trading processings.

Here, M is the integer greater than 1.

Step S422, client request corresponding business scenario according to each sub- trading processing, determine the mark of M block chain Know.

Here, the step S422 is it is to be understood that determine the business scenario of each sub- trading processing request one by one, according to These business scenarios determine the mark of block chain corresponding with these business scenarios.

Step S423, client respectively correspond according to the mark of each block chain and send corresponding sub- trading processing request To corresponding target block chain.

Here, after step S423 is it is to be understood that determine M target block chain, respectively by corresponding sub- transaction Processing request is sent to these target block chains, and then these target block chains respectively carry out corresponding sub- trading processing request Common recognition.

Above-mentioned steps S421 to step S423 provide it is a kind of realize " request of trading processing includes multiple business scenarios, The case where being known together by multiple target block chains " is individually located for the situation under multiple scenes using multiple block chains Reason, and be separately recorded in the account book of corresponding block chain, block the case where being lined up to avoid largely trading.

The embodiment of the present application provides a kind of transaction processing method of block chain, and Fig. 5 A is the friendship of the embodiment of the present application block chain The interaction flow schematic diagram of easy to handle method the described method comprises the following steps as shown in Figure 5A:

Step S501, client divide the block chain in the block chain network according to business scenario, obtain N group Block chain.

Step S502, client obtain trading processing request.

Step S503, in the N group block chain, client determines the first block chain according to the mark of the business scenario Mark.

Trading processing request is sent to target according to the mark of the first block chain by step S504, client Block chain.

Here, target block chain can be any group of block chain in above-mentioned N group block chain, for example, client is by area Block chain network is divided into four groups of block chains, and target block chain can be the first block chain in first group of block chain.

Step S505, target block chain receive the trading processing request that client is sent.

Here, the mark of Transaction Information and business scenario, and the mark of target block chain are carried in trading processing request Match with the mark of the business scenario.

Step S506, target block chain know together to the Transaction Information, and the successful result that will know together is recorded in institute In the account book for stating target block chain.

Here, after target block chain receives trading processing request, each node in target block chain is to the friendship Easy information is known together, and achievement of knowing together is not needed other block chains as a result, be recorded in the account book of the block chain It knows together.

In the present embodiment, target block chain receives the trading processing request of client transmission, for the trading processing The Transaction Information of request is known together, and is not needed other block chains and is known together, to be greatly saved total for Transaction Information The time of knowledge.

The embodiment of the present application provides a kind of transaction processing method of block chain, and Fig. 5 B is the friendship of the embodiment of the present application block chain Another interaction flow schematic diagram of easy to handle method, when trading processing request is assets transfer request, the transaction in assets is asked The assets side of being transferred to mark, the mark of the second block chain corresponding with the assets side of being transferred to mark and assets are carried in asking to turn Side's mark out, as shown in Figure 5 B, the described method comprises the following steps:

Step S521, client divide the block chain in the block chain network according to business scenario, obtain N group Block chain.

Step S522, client obtain assets transfer request.

Step S523, in the N group block chain, client determines the first block chain according to the mark of the business scenario Mark.

Here, for example corresponding business scenario business scenario phase corresponding with first group of first block chain is requested in assets transfer Together, then the mark of the first block chain is the mark of first group of first block chain.

Trading processing request is sent to target according to the mark of the first block chain by step S524, client Block chain.

Step S525, target block chain receive the assets transfer request that client is sent.

Step S526, target block chain determine ownership block chain according to the mark of the second block chain.

Here, the mark of the second block chain is corresponding with the assets side of being transferred to mark in assets transfer request.

Step S527, if the ownership block chain and the target block chain belong to same group, the target block The Transaction Information that chain carries assets transfer request is known together, and the successful result that will know together is recorded in the target area In the account book of block chain.

Here, in step S527, firstly, according to the assets side of being transferred to mark and the assets side of producing mark, target area Block chain generates assets transfer and requests corresponding digital asset；Then, target block chain knows together to the digital asset of generation, and Successful result of knowing together is recorded in the account book of the target block chain；That is, the assets side of producing in target block chain Corresponding node is identified, the corresponding digital asset of the digital asset transaction request is destroyed；It is described in the target block chain The assets side of being transferred to identifies corresponding node, generates the digital asset equal with destroyed digital asset；Finally, target block chain In each node know together to the digital asset of the generation, and the successful result that will know together is recorded in the target block In the account book of chain.The step S527 is it is to be understood that if the corresponding ownership block chain in the assets side of being transferred to and target block chain At same group, illustrate transaction in assets request for transaction in group, then target block chain is only needed to ask the assets transfer It asks the Transaction Information of carrying to know together, and successful result of knowing together is recorded in the account book of the target block chain, not The block chain for needing other to organize is known together.

In the present embodiment, when assets transfer request belongs to transaction in group, it is only necessary to which target block chain believes the transaction Breath is known together, to not only contribute to realize the concurrent of more stroke numeral transactions in assets, is improved transaction request, is also obviously improved The safety of digital asset avoids the risk that digital asset is attacked by unrelated malice block chain.

The embodiment of the present application provides a kind of transaction processing method of block chain, and Fig. 5 C is the friendship of the embodiment of the present application block chain The another interaction flow schematic diagram of easy to handle method, when trading processing request is assets transfer request, the transaction in assets is asked The assets side of being transferred to mark, the mark of the second block chain corresponding with the assets side of being transferred to mark and assets are carried in asking to turn Side's mark out, as shown in Figure 5 C, the described method comprises the following steps:

Step S531, client divide the block chain in the block chain network according to business scenario, obtain N group Block chain.

Step S532, client obtain assets transfer request.

Step S533, in the N group block chain, client determines the first block chain according to the mark of the business scenario Mark.

Trading processing request is sent to target according to the mark of the first block chain by step S534, client Block chain.

Step S535, target block chain receive the assets transfer request that client is sent.

Step S536, target block chain determine ownership block chain according to the mark of the second block chain.

Step S537, if the ownership block chain and the target block chain are not belonging to same group, the target area Assets transfer request is sent to the ownership block chain by block chain, so that the ownership block chain generates the assets transfer Request corresponding digital asset.

Here, it in step S537, in the node in the corresponding ownership block chain of the assets side of producing information, destroys The current digital asset of the digital asset transaction request；The section of the corresponding ownership block chain of information in the assets side of being transferred to In point, the digital asset equal with destroyed digital asset, and the corresponding number money of digital asset setting to generate are generated Produce mark.

Step S538, target block chain and the ownership block chain know together to the digital asset of generation, and will be total to Know successful result to be separately recorded in the account book of corresponding block chain.

Here, all nodes in all nodes and the ownership block chain in block chain are marked to the digital asset of generation It knows together, as shown in fig. 6, the block chain 00 in the first grouping 601 receives trading processing request, but the trading processing is asked The block chain for asking the corresponding assets side of being transferred to match is the block chain 10 in second packet, then information node 61 and message section Point 62 interacts, and knows together jointly to the Transaction Information of trading processing request.If target block chain is first group First block chain 00, ownership block chain are second group of first block chain 10, and block chain 00 and block chain 10 are to the Transaction Information It knows together, firstly, successful result of knowing together is recorded in the common account of group belonging to the block chain 00 by block chain 00, block Successful result of knowing together is recorded in the common account of group belonging to the block chain 10 by chain 10, then, passes through the two public accounts Fund trustship is done at family, when all participants reach common understanding to fund, can mutual dealing, and eventually by common account into Common recognition is answered into row timing reconciliation.

In the present embodiment, when assets transfer request belongs to transaction outside group, target block chain and ownership block chain are needed It knows together to the Transaction Information, transaction can be made fast so that the mode based on multiple groups multichain knows together to Transaction Information Fast, safe and stable reaches, and is not in the case where a large amount of transaction obstructions are lined up.

Under the block chain technical level of the relevant technologies, the main chain of entire block chain network only has one, this to work as area When block chain node is ever-increasing, performance will be lower, and the process of exchange of each stroke numeral assets is both needed to by block chain network Node common recognition on middle main chain, which calculates, to be completed, and the processing capacity for calculating and again relying on single node of knowing together, and the performance of single node There is the limit again in room for promotion.

Based on this, the embodiment of the present application devises multichain grouping distributed block chain account book framework, and single main chain is extended At the mode that multichain combines, by common recognition and across chain common recognition mechanism of exchange in multichain realization group, effective solution is in the related technology Existing blockage problem when only with a main chain processing transaction request.The embodiment of the present application is provided at a kind of transaction of block chain Reason method, Fig. 6 is the composed structure schematic diagram of the embodiment of the present application multiple groups block chain, as shown in fig. 6, according to block chain network pair The block chain network is divided into three groups of block chains (i.e. first group 601, second group 602 and third group 603) by the business scenario answered, There can be one or more block chains in each grouping.The block chain network includes the distributed frame of the block chain of multiple groups multichain Composition, each block chain have unique block chain to number (chain ID, Chain according to its packet positions in a network Identification), for example, the block chain of the first grouping 601 is identified as 0, then the block chain prefix in group is its grouping mark Know, the chain mark (Chain ID) of the block chain of the first grouping is 00,01,02 ... 0n, and each block chain is by several block chain links Point composition, each node carry out unique identification with (chain ID: node ID, Chain ID:peer ID), each block chain by going in The agreement of the heart maintains the sub- account book of itself.The block chain of second packet 602 is identified as 1, then the block chain prefix in group is it Packet identification, 10,11,12 in the chain identification information of the block chain of second packet；The block chain of third grouping 603 is identified as 2, Then the block chain prefix in group is its packet identification, the blocks such as 20,21,22 in the chain identification information of the block chain of third grouping Chain.Every group of block chain is connected directly with block chain fraternal in group, and is under the jurisdiction of block chain grouping.That is: in the first grouping 601 Block chain 00 is connected with other block chains in the first grouping 601.I.e. in the first grouping 601, block chain 00,01,02 is connected, In second packet 602, block chain 10,11,12 is connected, and in third grouping 603, block chain 20,21,22 is connected.Thus may be used See, each block chain is under the jurisdiction of a grouping, and corresponding multiple fraternal block chains, wherein passes through the chain ID energy of each block chain It is enough quickly to determine position of the block chain in entire block chain network.Information node 61 indicates the block of the first grouping 601 The corresponding node of chain, information node 62 indicate that the corresponding node of block chain of second packet 602, information node 63 indicate third point The corresponding node of block chain of group 603, information node 64 indicate the corresponding node of block chain of other groupings；And this four disappear Node is ceased, the grouping of corresponding block chain can be requested according to trading processing, is interacted；For example, the block in the first grouping 601 Chain 00 receives trading processing request, but the block chain that the trading processing requests the corresponding assets side of being transferred to match is second Block chain 10 in grouping, then information node 61 and information node 62 interact, and jointly to trading processing request Transaction Information is known together.

The block chain quantity for including in specific number of packet and each group in the present embodiment can be arranged by user flexibility.

Due to block chain network be include multiple groupings block chain distributed block chain network, pass through divide grouping Mode makes each block chain in system can be with independent process transaction related with this block chain, also, will generate digital asset Ownership block chain of the block chain as the digital asset, it can be seen that, each digital asset only corresponding unique ownership block Chain, and be only capable of carrying out relevant transactional operation by the ownership block chain, to not only contribute to realize that more stroke numeral assets are handed over Easy is concurrent, improves transaction request, has also been obviously improved the safety of digital asset, has avoided digital asset by unrelated malice The risk of block chain attack.

In the embodiment of the present application, by the difference of the corresponding business scenario of block chain, all transaction are divided into multiple groups Transaction in chain in group between multichain, organize in across chain transaction outside across chain transaction and group, make the transaction of all different blocks chains can be with Parallel, to increase substantially the performance of entire block chain network.

In addition each block chain network node in block chain network independent can carry out common recognition operation and book keeping operation operation. Specifically, each block chain is known together for being directed to the relevant transaction of block chain network node, and it is successful to know together Transaction record is in the account book of this block chain.Wherein, it is relevant to the block chain network node transaction include it is following at least It is a kind of:

Generation is traded in the chain of the block chain network intra-node, and is occurred in the network node and other block chains Across chain transaction between network node；Wherein, across chain transaction further comprises: occur same group of block chain network intra-node it Between across chain transaction, and across chain transaction between different group of block chain network node occurs.It can be seen that in the related technology Block chain network in only provide the mode difference of a unified common recognition operation entry (in block chain network in the related technology The common recognition operation of All Activity must all be realized via the unified common recognition operation entry, thus can not concurrently execute multiple friendships Easily), the mode in the application, which is equivalent to, provides multiple common recognition operation entry (each block chain network sections that can be used parallel All had in point one be capable of complete independently common recognition operation entrance), and each block chain network node only for its phase The network trading of pass is known together, other block chain network nodes unrelated with the transaction are not involved in the common recognition behaviour of the transaction Make, therefore, can concurrently carry out the common recognition operation of multiple transaction, not only improve the concurrency of system, but also reduce common recognition behaviour The time delay of work.Also, (blocks in the related technology different from the one big mode of account book is only provided in traditional block chain network Chain network records each transaction between all block chain network nodes by one big account book), the mode in the application is suitable In providing multiple independent lower account books, (each block chain network node all has the account for capableing of complete independently book keeping operation operation This child node), also, the account book in each block chain network node need to only record transaction relevant to the block chain network node Account, without recording the transaction account unrelated with the block chain network node, to improve the efficiency of book keeping operation and inquiry.

The embodiment of the present application provides a kind of transaction processing method of block chain, when digital asset transaction request is assets transfer Request, and the corresponding business scenario of assets transfer request business scenario corresponding with first group of first block chain is identical, if Block chain corresponding to the assets side of being transferred to is first group of first block chain, the step of common recognition to the digital asset transaction request It is as follows:

The first step determines the assets side of the producing information and the assets side of producing information for including in assets transfer request.

Here, the assets side of producing information includes the chain ID of the corresponding block chain in the assets side of producing and the assets side of producing；Assets The side's of being transferred to information includes the chain ID of the corresponding block chain in the assets side of being transferred to and the assets side of being transferred to.

Second step determines that block chain corresponding to the assets side of being transferred to is first group of first area according to the assets side of being transferred to information Block chain (i.e. target block chain).

Third step destroys digital asset transaction in the corresponding node of the first group of first block chain assets side of producing information Request corresponding digital asset；In the corresponding node of the assets side of being transferred to information, generate equal with destroyed digital asset Digital asset, and corresponding asset identification is set for the digital asset generated；

Here, the assets side of producing information, for being supplied to the first block chain, so as in the first block chain destroy and The corresponding digital asset of digital asset transaction request；The assets side of being transferred to information, for being supplied to the first block chain, so as to Generate the digital asset equal with destroyed digital asset in one block chain, and to be generating with destroyed digital asset etc. Corresponding digital asset identification and new assets holder information is arranged in the digital asset of volume.

4th step carries out common recognition in group to digital asset identification using each node in first group of first block chain.

Here, common recognition can be understood as common recognition on single-stranded and calculate in group, for there are several block chains in a group can To pass through programming Control, it is generally the case that an only chain in every group.

In the present embodiment, when digital asset transaction request is that assets transfer is requested, and assets transfer request is corresponding Business scenario business scenario corresponding with first group of first block chain is not identical, if block chain corresponding to the assets side of being transferred to is Second group of first block chain, the step of knowing together to the digital asset transaction request, are as follows:

Second step determines that block chain corresponding to the assets side of being transferred to is two group of first block according to the assets side of being transferred to information Chain (organizes outer block chain).

Here, if it is determined that block chain corresponding to the assets side of being transferred to for including in assets transfer request is second group first Block chain is to judge that assets transfer request belongs to outer across the chain transaction of group.

Assets transfer is requested the corresponding assets side of producing information to be sent to second group by third step, first group of first block chain First block chain.

4th step destroys digital asset transaction in the corresponding node of the second group of first block chain assets side of producing information Request corresponding digital asset；In the corresponding node of the assets side of being transferred to information, generate equal with destroyed digital asset Digital asset, and corresponding asset identification is set for the digital asset generated；

Here, the assets side of producing information, for being supplied to first group of first block chain, so as in first group of first block chain Corresponding digital asset is requested in middle destruction and digital transaction in assets；The assets side of being transferred to information, for being supplied to second group first Block chain, to generate the digital asset equal with destroyed digital asset in second group of first block chain, and to generate Corresponding digital asset identification is set with the equal digital asset of destroyed digital asset and new assets holder believes Breath.

5th step, first group of first block chain and second group of first block chain jointly know together to asset identification, and will Successful result of knowing together is separately recorded in the account book of first group of first block chain and the account book of second group of first block chain.

Here, since this Transaction Information is related to two block chains, therefore, it is necessary to two block chains to know together and keep accounts jointly. As shown in fig. 7, first group of block chain 701 includes multiple block chains: block chain 00, block chain 01, block chain 0n, the There is a common account 71 in one group of block chain 701, the common account 71 is for across the chain common recognition between different groups of block chains；The Two groups of block chains 702 include multiple block chains: block chain 10, block chain 11, block chain 1n；Second group of block chain There is a common account 72 in 702, the common account 72 is for across the chain common recognition between different groups of block chains；Third group block chain 703 include multiple block chains: block chain 20, block chain 21, block chain 2n；There is one in third group block chain 703 Common account 73, the common account 73 is for across the chain common recognition between different groups of block chains；4th group of block chain 704 includes multiple Block chain: block chain 30, block chain 31, block chain 3n；There is a common account 74 in 4th group of block chain 704, The common account 74 is for across the chain common recognition between different groups of block chains.

In the present embodiment, block chain (i.e. first group first block chain of the digital asset transfer request across two groups With second group of first block chain), this two block chains are traded mutually by the common account of corresponding group, realize common recognition.First The privately owned account book of the first block chain of group is not necessarily to the privately owned account book for going to trust second group of first block chain, because of the two block chains pair In the assets transfer request known together during, by the two common accounts (common account 71 and common account 72) come Do fund trustship, when first group of first block chain and second group of first block chain reach common understanding to fund, can mutual dealing, And reconciliation is timed to reach common understanding eventually by common account.

Transaction processing method based on a kind of block chain that the application proposes, may be implemented in bilateral credit problems to comment The operations such as authenticity, transaction authenticity are grouped subregion, and comment can independently know together, and transaction can also be independently total to Know, and every transaction may be implemented laterally to divide chain, support the quick common recognition under big concurrent transaction scene.Such as go on a journey in travelling In, each transaction is created by intelligent contract, and each contract is synchronous via all nodes, as shown in figure 8, Under bilateral travelling scene, user comment module 801 respectively corresponds different groups of block chain from trades record module 802, such as The relevant operation of user comment is carried out in first group of first block chain, and it is related that transaction record is carried out in second group of first block chain Operation, can guarantee that the content of user comment in user comment module 801 can not distort in this way, and transaction record mould Transaction record in block 802 is also that can not distort；Then, content of the node in first group of first block chain to user comment It knows together, the node in second group of first block chain knows together to transaction record.Finally, by the content and friendship of user comment Easily record is synchronized in the centralization database 803 of third-party platform, and either server or consumer cannot be direct False sales volume is manufactured by the centralization database 803 of third-party platform, elimination difference is commented；In this way, the mode based on multiple groups multichain It can make quick, safe and stable the case where reaching, being not in a large amount of transaction obstruction queuings of trading.
