Specific implementation mode
Before the various embodiments to the application absolutely prove, for ease of understanding, first to some basic backgrounds into
Row is introduced.Though block chain technology is born, the time is not grown, because it is with decentralization, tamper-resistance properties, to be easy to tracking backtracking etc. aobvious
Work feature makes it start the climax of application in all trades and professions at present " in the ascendant ".Nevertheless, in block chain technology
Hold, then may not people all know to the greatest extent.Block chain technology is briefly that the various transaction records that will be generated on network are published each
Among block, each block constitutes block chain according to the connected chaining of certain logic rules.As a result, from simply introducing block
The needs of chain technology set out, and can be divided into two large divisions's content and be explained：First, the institutional framework of block chain；Second is that how to complete
The process of transaction data cochain.
Referring to Fig. 1, the figure shows a kind of schematic constructions of block chain institutional framework.As shown in Figure 1, every on block chain
A block can be divided into block body and block head according to the difference of function, the former is mainly used for recording transaction data,
Can include a plurality of transaction data, the latter is mainly used for identifying this block, and links other blocks.Comprising upper in block head
The cryptographic Hash (father's block Hash) of one block and the cryptographic Hash of this block, local area block header include the Hash of a upper block
Value, thus sets up the contact of this block and a upper block, and the cryptographic Hash of this block is used to be written the block head of next block
Part is achieved in and is contacted with next block.Each independent block has been gone up by the hash connection in block head,
And then constitute a complete chain, block chain thus gain the name.Certainly, in practical applications, each area block head in the block can
Can include not only these contents, it is also possible to comprising Merkle roots (value by All Activity data in block body cryptographic Hash two
Two step by step Hash calculation obtain【May also other modes obtain】, be mainly used for examining certain transaction whether there is in this block it
In), timestamp (generation time for recording the block), difficulty value (be used to indicate the difficulty that each block obtains " book keeping operation power "
Degree), random number (answer for being mainly used for record answer " book keeping operation power " problem) etc..
Compared to the institutional framework of block chain itself, the uplink operation of transaction data is increasingly complex, more core.Such as Fig. 1
Shown in block formed block chain be to be performed by the node in block chain meshed network.Block chain meshed network can include
Multiple block chain nodes, these block chain nodes " mutually assisting " complete the cochain of transaction data jointly.First, when an area
After block chain link point receives a transaction data, in order to enable the transaction data obtains " recognizing " of block chain the whole network, it can be broadcast to
Other each block chain nodes；After each block chain link point receives the transaction data, when carrying out verifying and correctly covering to it
Between stab, in order to strive for recording " the legal book keeping operation power " of the transaction data, which needs that scheduled " mathematics is difficult by solving
Topic " (i.e. proof of work mode) is realized；It is weighed when some block chain node wins the legal book keeping operation by " self-efforts "
Afterwards, it will broadcast all transaction for being stamped timestamp before completing cochain to this block from after last time block cochain to the whole network
Data are checked by each block chain link point, are verified.After other block chains of the whole network have verified correctness, current block is realized
Cochain, and will enter next block cochain it is legal book keeping operation power " plunder ", thus recycle.
When understanding the basic scheme of block chain technology, there is the worth explanation of several points：
First, the concept about transaction data.Transaction data, transaction record in above process etc. are broad sense, not single
Singly refer to and complete payment, this commercial behavior of collecting money between two nodes, also refers to something other with exchange value
Part.For example, A initiates the user terminals game events data such as magic event, but the term to launch a offensive event, B of B in online game
It is generally also associated with block chain, that is to say, that the transaction data is block chain to be gone up or the number for having a mind to block chain
According to being different from simple some numbers for being handled by block chain meshed network but not required cochain or be not directly dependent upon with block chain
According to.
Second is that the transmission about data between block chain node.Include multiple block chain links in block chain meshed network
Point may at every moment carry out the exchange of data between these nodes, how ensure the safety for the data that these are exchanged, and be packet
Include the various data broadcast techniques problem needed to be considered including block chain technology.In the range of the application is described, the biography
Passing process usually can take data signature technology to be ensured that basic procedure is as follows：When A nodes send message to B node
(for example a transaction data forms a message), A nodes carry out Hash calculation using hash function to message text, generate report
Digest is wanted, and the private key of oneself is used in combination to encrypt the abstract, encrypted abstract by as the digital signature of message and message together
It is sent to B node.After B node receives the message, fallen into a trap from the original message received with hash function identical with A nodes
Message digest is calculated, then the digital signature of COM Continuation of Message is decrypted with the public key of A nodes again, if the two abstract phases
Together, then B node just can confirm that the digital signature is A nodes, message comes from A nodes.It is prominent for the convenience and emphasis of narration
Go out, will not highlighted in the subsequent discussion of the application.
Third, the other technologies problem about block chain.It is right since the application will be unfolded around the technical solution of the application
In the technology contents little or basic with the application relevance, will not refer in detail, those skilled in the art should be understood that
When necessary, the technical solution of the application can be implemented using these basic technological know-hows.
There is above-mentioned specific block chain structure and upper chain rule just because of block chain technology, so that block chain is had aforementioned
The distinguishing feature sayed.But with the expansion of Web vector graphic range, the transaction data amount generated based on network is increasing,
This will cause it when being combined with block chain technology, and the block chain of generation is increasingly longer, and each block on block chain includes
Transaction data record is more and more, and the data transfer synchronizing process of block chain meshed network is more and more slower, seriously affects area
Block chain technology is further applied.For solve the problems, such as or improve it is existing in the prior art this, the embodiment of the present application propose it is " more
The technical solutions such as chain " multichain is parallel " carry out data processing.
Referring to Fig. 2, the figure shows the data processing method provided by the present application based on block chain, this method includes：Step
Rapid S201：Block chain meshed network receives the transaction data of block chain to be written, and the transaction data corresponds to block chain identifier；
Step S202：Block chain meshed network determines and the block chain according to the block chain identifier from least two block chains
The corresponding block chain of identifier；Step S203：Block chain meshed network identifies transaction data write-in with the block chain
Accord with corresponding block chain.
When understanding this technical solution, block chain identifier and related content cannot be narrowly understood.Block chain identifies
Symbol is associated with the quantity of block chain, if an only block chain, the transaction data that block chain meshed network receives will
" straight " the block chain is written, and selects, determined the leeway of the block chain of operation in a plurality of block chain of having no way of, only exists more
When block chain, the block chain that just it is necessary to block chain identifier is arranged to distinguish different.But still need to pay attention to one especially
The problem of：There is the block chain identifier for distinguishing block chain, is not meant in block chain meshed network certain individually with one
A field for distributing, memory block chain identifier, the purposes mainly expressed is to discriminate between different block chains, and this differentiation can
Being realized using the block chain identifier of " dominant ".For example, in a corresponding table, there are block chain identifiers and block chain
Mapping, can find corresponding block chain using the block chain identifier.The differentiation of block chain can also use " recessiveness "
Block chain identifier realize.For example, some attributes (or transaction data class of transaction data or transaction data to receiving
Type, the attribute of application etc. for generating transaction data) operation is carried out, corresponding block is assigned it to according to the result of operation
Chain.If the attribute value of some attribute of transaction data is 100 or transaction data sheet is as 100, it can " ask
It is remaining " operation, if " mould " is set to 10, it can determine that the transaction data will be written into No. 0 block chain；If attribute value is 101
Or transaction data sheet can then determine that the transaction data will be written into No. 1 block chain as 101, and so on.In addition, by
Above-mentioned narration as it can be seen that block chain identifier can have " aobvious hidden " exceptionally, can also have it is " directly indirectly " not, i.e. block chain
Identifier can be independently of the character or character string of an index block chain of transaction data or block chain, can also be pair
The attribute of transaction data itself or transaction data carry out operation after as a result, generally, block chain identifier is block chain
Index, this index can be " direct-type " index (mark in the independent mapping table established as the aforementioned is as block
Chain identifier), can also be set up after certain calculation process mapping " indirect type " index it is (such as aforementioned to transaction data
Carry out the result after complementation operation), the specific form of expression depends on the concrete mode of positioning block chain.
The technical solution makes transaction data innovatively correspond to block chain identifier, and utilizes the block chain identifier selected
Some block chain, and then among some transaction data is written to some specific block chain, it is such " orderly sorting out " so that
Complicated in the past and single block " long-chain ", becomes flexible, short and small block short chain, will " singles solely struggle against " the operation change of block chain
At collective's cooperating process of " division of labor is clear ", to bring a series of excellent technique effect.
First, the size of block can be substantially reduced using multichain mode.As previously mentioned, in the prior art, previous block
After cochain to new block generate between All Activity data, will be by the block body of " packing " to a block, in this way
It will make the size extremely " too fat to move " of single block, and in the case where taking multichain scheme, transaction data " is sorted out into chain ",
Data in the block of each chain are with same alike result, same size or the same category in terms of some, in area friendship in the block
The amount of easy data will be reduced, to realize " shrink " and " weight reducing " of single block.For example, under single-stranded situation, each block
10M, if using 10 block chains, in identical TPS, (transaction per second, trading volume per second are to weigh area
The index of block chain transactions velocity) under demand, as long as each block can be with 1M.
Secondly, can effectively reinforce storing efficiency using multichain mode.Since each block is by " weight reducing ", single block chain accounts for
It is reduced with space, is not enough to leave the memory space of " huge chain " originally, can be used for storing the block chain after these " shrinks ",
To take full advantage of the small space in storage device and " fragment space ", distributed storage mode is also conveniently taken.Meanwhile it will
Originally have to occupied large space and " monoblock space " for really storing the block chain for needing such size really.By
This, can make itself to receive benefits and other blocks (block chain) are beneficial, effectively strengthen the storage effect of block chain meshed network
Energy.
Again, efficiency of transmission can obviously improve using multichain mode.The moment carries out each in block chain meshed network
Data exchange between block chain node, these data transmissions are to transmit for the first time a bit, some are transmitted again after mistake, some
It is transmission data itself, some are the association messages for verification of transmission data.In the prior art, one " giant "
The transmission of block chain, a possible character mistake will cause full chain wrong, and the Except block data itself transmitted are outer, may also have area
The additional informations such as block size, height, quantity, these have all aggravated the transmission burden of block chain meshed network.And pass through multichain side
Formula, it is single-stranded " body is healthy and strong gently ", the chain data can be transmitted after the extremely short free time for listening to channel, and due to the chain of transmission
Small, error probability becomes smaller, even if error, without the re-transmission of large area, is only retransmitted with regard to the chain.It can be seen that using more
Chain mechanism will be obviously improved efficiency of transmission.
It is again secondary, checkability can effectively be enhanced using multichain mode.It, will in place of being verified there are many places in block chain technology
When the data of cochain enter block, the verification of data validity can be carried out；Block data is sent to another by a node
When node, the signature verification of data source will be faced.For example, user A will give user B to send out 4 coin, then, it first has to verify user A
Whether have the ability to send out 4 coin, to ensure the authenticity of transaction.User A may not have 4 coin in current transaction, when for list
When one long-chain, it may be necessary to go to have searched whether that other people sent out extra 4 to party A-subscriber in the historical chain of " disorderly and unsystematic "
A coin, or wait for party A-subscriber send out extra 4 coin but be not synchronized to the information of this node also, this will all cause to verify
The extension of process.If using multichain mode, due to it may be integrated into same chain entirely with the relevant transaction of party A-subscriber among, because
And historical data can be successfully found very much for verifying；Even if not in the same chain, due to the raising of efficiency of transmission, also can and
When obtain relevant information, so as to shorten the verification time, achieve the purpose that improve verification efficiency.
The above has absolutely proved the good result that " multichain " mechanism is brought to block chain technology, in fact, making multichain
Machining function plays more fully mode and also resides in " parallel ", i.e. not only multichain, but also each block chain can execute parallel.One
Kind possible " multichain is parallel " embodiment is to include the situation of intelligent contract in transaction data, when including intelligence in transaction data
When contract, (for example, including the first number of deals of the first intelligent contract when block chain meshed network receives different transaction data
According to the second transaction data for including the second intelligent contract, two transaction data of person can receive in same batch, can also
Received in different batches), respective transaction data, which is written, respectively for the different blocks chain node in block chain meshed network corresponds to
Block chain (for example, the first block chain, area is written in the first transaction data by a block chain node in block chain meshed network
The second block chain is written in second transaction data by another block chain node in block chain meshed network), when being written in block chain
Intelligent contract when meeting trigger condition, independently execute respective intelligent contract (for example, the first intelligent contract is touched meeting
Automatic to execute the first intelligent contract when clockwork spring part, the second intelligent contract when meeting trigger condition, close by automatic second intelligence that executes
About).Two block chains respectively carry out transaction data reception as a result, transaction data enters chain and the execution of intelligent contract,
Independently of each other, do not depend on each other, to reduce be lined up, it is crowded, timely feedback result after intelligent contract has executed.Be above with
For intelligent contract, even if being not the case, when other need parallel execute, reason is similar, no longer superfluous words.
Foregoing teachings are mentioned the checkability that multichain mechanism is brought and are promoted, and parallel mechanism is brought on multichain basis
Execution efficiency promoted, but this only from the overall effect for.In some actual business procedure, it may show
Go out the disadvantage " across chain ".When parallel there are multichain, the polytropism feature of the polyphyly and target in the source merchandised due to one
(referring to Fig. 3 A) is likely to occur complicated situation for certain transaction data (business), the transaction data in a block chain with
There may be following several fundamental relations between other transaction data：
First, being located at the same block of same block chain, i.e. independent blocks relationship, it is not closed with other transaction data
Connection, transaction data block 31 as shown in Figure 3B；Second is that positioned at the different blocks of same block chain, i.e. transregional piece of relationship is such as schemed
Transaction data block 32 shown in 3B, its whereabouts are directed toward the (arrow in such as figure of another area transaction data in the block under this block chain
Shown in head)；Third, in the block of different blocks chain, i.e. bridging relationship, transaction data block 33 as shown in Figure 3B, it
Source may be the block (as shown by arrows in figure) in another block chain.
Existing different blocks relationship, may be such that it is had differences in terms of the difficulty of verification and speed between transaction data.
For the first situation, only verified in this block of this chain, efficiency is higher；For second case, while it is desirable to search
Other blocks, but without departing from the range of this block chain, also can comparatively fast realize verification；For the third situation, then need across chain
Verification, across chain verification need to position block chain, and foundation takes the difference across chain mode, it may be desirable to more times.For this purpose,
After the scheme for taking multichain parallel, the producing method of transaction data should be optimized, transaction data returns chain mode etc., to the greatest extent may be used
Across chain transaction can be reduced, the trouble of across chain verification, waiting verification is saved.Here it does not describe further.
The above-mentioned data processing scheme based on block chain is run and implements in block chain meshed network, below to area
Block chain meshed network is introduced.Referring to Fig. 4, the figure shows the network structures of " pyramid ", are divided into client layer, routing section
Spot net layer and block chain meshed network layer, below first illustrate block chain meshed network layer, are being related to for follow-up two layers
It is illustrated when corresponding technical solution.It is block chain meshed network in block chain meshed network layer, block chain meshed network is safeguarded
At least two block chains identified by block chain identifier, the network include multiple block chain nodes.Here block " is safeguarded "
Chain is to need to complete the relevant feature operation of block chain, the normal function of realization block chain according to block chain technology.In block
It is connected with each other between node in chain meshed network, specific connection type can be divided into " directly jumping formula " connection and " jump formula " even
It connects, under former mode, node centering at least a pair that the chain link point of block two-by-two in block chain meshed network is formed has
One distance jumped, i.e. at least one node can directly reach destination node, certainly, most in transmission data without transfer
Excellent mode is all hop distances, i.e. " full interconnection " pattern；Under latter approach, the area two-by-two in block chain meshed network
The node centering that block chain link point is formed is at least a pair of, and there is the distance jumped at least more than one, i.e. at least one node to transmit
When data, the transfer by other nodes is needed to achieve the goal node.Above two mode has respective advantage and disadvantage, for first
Kind mode can improve efficiency of transmission, especially all nodes in block chain meshed network are all made of due to " can directly jump "
When which, but this mode may increase link cost, and in the case of this " full interconnection ", each address of node is equal
It can inquire, network attack may be caused；For the second way, since most of node is using " jump " formula, although transmission effect
Rate is lowered, but this loose formula connection taken, it is ensured that the safety and robustness of network.
Block chain meshed network safeguards multiple block chains, which includes multiple block chain nodes, these nodes can be with
" equality " go to safeguard all block chains, robbed from multiple nodes in the conventional mode " book keeping operation power ".For example, block chain link
Any block node in spot net receives the transaction data of block chain to be written, and then the block chain node passes through aforementioned
The distance of distance or multi-hop that one sayed jumps, other all block chain nodes which is broadcast in the whole network,
It after block chain node each in this way takes transaction data, can be recorded among block, and go competition complete on this basis
" the book keeping operation power " of net.But this mode may lead to " waste " of computing resource because each node in the whole network go into
The calculating of row difficult math question, and final " can make one's wish fulfilled " there are one node.For avoid it is this " seem fair, it is actually low
The mechanism of effect " injures " entirety ", and a kind of method of accommodation is that specific transaction data gives specific block chain node (for such
Node can be elected by other nodes, either according to scheduled rule serve as in turn the node function or according to
Pre-defined rule preassigns), it is completed by specific block chain node " book keeping operation " of block chain, then " account book " is synchronized to block chain
Other block chain nodes in meshed network, that is, establish the mapping between " transaction data -- block chain node -- block chain "
Relationship, this mapping relations of connecting are block chain identifiers, i.e. transaction data corresponds to block chain identifier, according to block
Transaction data is transmitted to scheduled block chain node by chain identifier, and being accomplished to block chain identifier in the block chain node corresponds to
Block chain uplink operation.This mode avoids " harmful competition " between block chain node, but " Each performs its own functions ",
" respectively with regard to its position ".Although thus, include multiple block chains in block meshed network, but each node only safeguards one
Or the block chain of limited quantity, the block chain of oneself oneself is safeguarded, newest block chain is then synchronized to other nodes, from
And so that each block chain node possesses identical block chain copy in the whole network, but " having a finger in every pie " is gone without each block chain,
Substantially increase the efficiency of entire block chain meshed network.
It is above-mentioned that each node " Each performs its own functions " in block chain meshed network is allowed respectively to be received although each have their own task
Respective transaction data and completion uplink operation, but this is also another " equality ".And practical business is multifarious, number of transaction
Number differ, and be based on cost meter, can further consider the node " division of laborization " in block chain meshed network.Tool
The way of body can be, be two classes by the node division in block chain meshed network：One kind is block chain execution type node, a kind of
It is block chain service type node, at least a pair of distance for having one to jump of the node centering formed between two class nodes.Execution type
The distance jumped two-by-two with one is kept between node, it is at least a pair of in being kept two-by-two between block chain service type node to have greatly
In the distance that one jumps, the former is used to undertake the groundwork of block chain, for example, generating block and completing the operations such as block cochain；
The latter be used for undertake routing and aforementioned " scheduled block chain node " election, routing work be received by it is to be written
The transaction data of block chain, and block chain execution type node is forwarded it to, election is in some scheduled block chain
When execution type node cisco unity malfunction (or when meeting preset condition), execution type section is become from some service type node
Point, to undertake the responsibility of former block chain execution type node.
In a kind of block chain meshed network of optimization, between block chain execution type node and block chain service type node extremely
The distance of few " one jumps ", ensures that transaction data when playing routing function, is transferred to area by block chain service type node well
Block chain execution type node.Certainly, it is more fully to play this kind of effect, it can be according to the block chain execution type of actual requirement whole
Node is kept with corresponding block chain service type node at a distance from " one jumps ".In the block chain meshed network of another kind optimization
In, since block chain executes the core status of node in the entire network, configuration is usually higher, and such configuration determines it
It is not possible that quantity is more, therefore, the quantity of block chain execution type node can be arranged to be less than block chain service type node, this
Sample acquirement keeps certain balance between " cost, function, quantity " several persons.
Above content introduction block chain meshed network layer, pyramid structure as shown in Figure 4, block chain meshed network is not
It is isolated network, it needs to receive transaction data, and transaction data results from client layer, then transfers to routing node network layer
Node-routing is to block chain meshed network layer.It will be appreciated by those skilled in the art that a kind of situation be, client layer generate transaction
After data, transaction data is directly supplied to the block chain execution type node in block chain meshed network, still, due to this side
Formula " will be nervously fumbled ", or even can not handle when facing big data quantity, and strongly limit the application of block chain technology.For example,
Some scenes not high to requirement of real-time are simply possible to use in, have such as seen the financial field of implementation and simple game.And it actually answers
With in the process, big data quantity has become trend and unavoidable reality, such as online game, will generate in a short time big
The transaction data of amount, will be unable to solve that this requirement of real-time of online game is very high, data volume is great according to existing pattern
Application scenarios.For this purpose, the embodiment of the present application proposes a kind of feasible solution, in client layer and block chain meshed network layer
Between be arranged routing node network layer, routing node network layer upwards (upstream message direction) connect block chain link spot net layer,
(downstream message direction) connects client layer downwards, and the transaction data from client layer is accepted downwards by routing node network layer,
Transaction data is transferred to block chain meshed network layer upwards, and the network bandwidth of routing node network layer is fine, and without occupying
A large amount of memories or hard drive space are come operation of completing " to keep accounts ", so as to adapt to the process demand of big data.
It can be seen that using the pyramid network structure of the embodiment of the present application, online game face can be preferably solved
The problem of facing, in the same way, the scheme of the present embodiment can be used in the application high for those requirement of real-time, data volume is big.
For online game or similar application, can also further optimize herein.For example, online game class is answered
In other than this kind of data of transaction data, actually there is also the data that need not be much recorded in block chain, in order to fill
Divide using " hardware facility " according to above-mentioned Model Establishment, " two-in-one " mechanism may be used, i.e., by the application of online game class
Data processing needs that are to be treated but need not going up block chain merge in pyramid structure above-mentioned, specifically, coming from
The file server requests of client layer are forwarded to block chain meshed network layer by the forwarding of routing node network layer, to avoid pair
The influence of block chain process handles this document service request by the service type node in block chain meshed network layer, if place
The file server requests of reason need to return to message, then return to client layer via routing node network layer.Certainly, according to this
Thinking, the service type node in block chain meshed network layer can not only be merely responsible for processing file server requests, can also undertake
Some cachings, for example some graphic files needed for game such as calling of playing, draftings are buffered in service type node
Among, so as to accelerate processing and response of the service type node to association requests.Certainly, another feasible mode is to give way
The pooling feature of part is also undertaken by meshed network layer.
