It records (also known as block).The keyed hash, corresponding time stab and transaction data that each block contains previous block are (logical
The hashed value that common Merkel's tree algorithm calculates indicates), such design is so that block content has the characteristic being difficult to tamper with.With
The distributed account book that block chain is concatenated can allow two sides effectively to note down transaction, and can permanently check this transaction.
Block chain can be generally divided into publicly-owned chain, alliance's chain and privately owned chain according to access authority.Publicly-owned chain refers to anyone
The block chain of common recognition can be accessed and joined according to agreement；Alliance's chain refers to the block that common recognition process is controlled by preselected node
Chain；During privately owned chain refers to that permission is organized at one, and the block chain fully controlled by the tissue.
Block chain is generally divided into several big technical points such as common recognition algorithm, cryptography, P2P network in technological layer.Wherein
Algorithm of knowing together is part most crucial in block chain project.It is distributed formula, it is necessary to reach common understanding.So far, for block
The maximum technical point of chain project dispute is also common recognition algorithm.
For alliance's chain due to more demanding to performance, delay etc., the common recognition algorithm majority suitable for alliance's chain is based on synchronization

When, it is larger to will lead to block volume, often blocks common recognition process since encrypted communication is excessively slow, or even common recognition process can be made to stop
Only.
Currently, generalling use PBFT (practical Byzantine failure tolerance algorithm) under alliance's chain scene and drilling the various of PBFT
Change version as algorithm is known together to support the operating of block chain, under most of application scenarios, PBFT common recognition algorithm is effective,
Solves the demand of most of alliance's chain scene.
However, while bringing high-performance, low delay, defect that PBFT common recognition algorithm also has its intrinsic.Due to
The message communication amount of PBFT algorithm is larger, and in the case where number of nodes is more (up to a hundred), common recognition performance is greatly lowered, and is delayed
Substantial increase.And in the case where comparatively extreme, common recognition process can not go on.Which results in PBFT common recognitions
Algorithm can not be run in the distributed network of (number of nodes is up to a hundred to several hundred) fairly large in number of nodes, be designed based on this algorithm
Block catenary system, property extending transversely is poor.

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached in the embodiment of the present invention
Figure, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only this
Invention a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
Embodiment one
The block chain transaction confirmation method based on asynchronous multichain that the present embodiment provides a kind of, belongs to field of computer technology,
Suitable for a variety of block chain trade confirmation business scenarios based on asynchronous multichain, especially suitable for alliance's chain technology.
In alliance's chain, traditional common recognition algorithm based on transaction common recognition is usually adopted to support biggish node size
With the form of transaction the whole network broadcast.Interconnection is very high between the usual node of alliance's chain, and which results in network communication amounts
High, when the load of block chain network is higher, the volume that will lead to block is larger, often hinders since encrypted communication is excessively slow
Common recognition process is filled in, or even common recognition process can be made to stop.For this purpose, the present embodiment provides a kind of, the block chain based on asynchronous multichain is traded
Confirmation method realizes that the transmission of block and common recognition are completely asynchronous.
Fig. 1 is a kind of flow chart for block chain transaction confirmation method based on asynchronous multichain that the present embodiment one provides, such as
Shown in Fig. 1, it is somebody's turn to do the block chain transaction confirmation method based on asynchronous multichain and specifically comprises the following steps:
The domestic transaction information package that first node in S1, block chain network is stored is at the first block and adds
It is broadcasted in block chain network into the block chain of first node, and by the first block.
Specifically, step S1 specifically includes following sub-step:
S11, first node Collection and conservation are in local domestic transaction information.
In the present embodiment, first node is the arbitrary node in block chain network.
Specifically, the arbitrary node in block chain network receives client and is sent to the Transaction Information on the node, only exists
It is stored and is safeguarded on the node, without being broadcasted into block chain network.It should be noted that signified in the present embodiment
Transaction Information, refer to client trading object to be transacted.
In the present embodiment, after arbitrary node receives the Transaction Information of client transmission, without the broadcast traded, pole
The earth reduces the consumption of Internet resources.
The domestic transaction information package that S12, first node are stored is at the first block.
Specifically, all nodes in block chain network will be respectively stored in local simultaneously when triggering is packaged out block
Multiple domestic transaction information are packaged into block respectively, and a domestic transaction information package is at a block.
First block is added to the block of the first node constructed in advance by S13, first node by block Hash
In chain.
Therefore, in the present embodiment, before step S1, this method is at least further include: the area of S0, in advance construction first node
Block chain, the step include at least following sub-step:
S01, first node receive several Transaction Informations that relative client is sent；
S02, several Transaction Informations are stored in present node local；
S03, several Transaction Informations are packaged into several blocks respectively；
The block chain of the first node is formed between S04, several blocks using block Hash head and the tail connection.
When constructing the block chain network, each node respectively beats several Transaction Informations for being stored in present node respectively
Block is wrapped out, is connected between block and block using block Hash (Hash) head and the tail, forms the traditional chain structure that can not be distorted, Mei Yijie
Point respectively safeguards the block chain of respective node.Later, when the node receives new Transaction Information, equally by the new transaction
Information package is blocking, is added in the block chain.
S14, first node broadcast the first block in block chain network.
Specifically: the block in block chain that each node is respectively safeguarded is broadcasted into block chain network.
It illustratively, include tri- nodes of A, B, C in block chain network, node A is after step S1, the block of maintenance
There is A in chain1、A2、A3Three end to end blocks, node A broadcast three blocks to block chain network.
In the present embodiment, the broadcast of block and the process of common recognition are completely asynchronous, therefore the broadcast speed of block and entire area
Load in block chain network can't cause large effect to the process of common recognition, so that it is preferable to have the block catenary system
Property extending transversely.
Second node in S2, block chain network receives and verifies the first block, and the first block is stored if being verified
And the first block for constructing the first block finds information, and the first block discovery information is broadcasted in block chain network.
Specifically, step S2 includes following sub-step:
Second node in S21, block chain network receives the first block of first node broadcast.
S22, the block information for verifying the first block.
Specifically, by the public key of verifying first node, first node to the signature of the first block, the block of the first block
Size, the block height of the first block, the block information of first block such as father's block Hash of the first block verify the firstth area
Block.
S23, it after obtaining verification result, is specifically handled as follows:
If being verified, second node stores the first block to second node local, constructs one by lightweight data
The first block that structure is constituted finds information, and the first block discovery information is broadcasted in block chain network, wherein block hair
Existing information includes at least block Hash, present node to the signature and present node public key of block Hash.
If authentication failed, the first block is abandoned；
In the present embodiment, second node is the arbitrary node in block chain network in addition to first node.
Illustratively, firstly, broadcasting block A in node A1、A2、A3Afterwards, node B and C receives these three blocks, and
Block is verified using identical method.It is further described by taking node B as an example below, Node-B receiver to node A is broadcasted
A1、A2、A3Three blocks, and by verifying node A to the signature of each block, the block size of each block, Mei Gequ
The block height of block, each block father's block Hash etc. verify these three blocks.
It is verified, block A1、A2By verifying, then node B is by block A1、A2It is maintained in local, and construction is corresponding respectively
Block find information.Block A is constructed with B node1Block discovery information for, A1Block discovery information includes at least: A1Area
The block Hash of block, B node are to the signature and B node public key of block Hash.Node B uses same method construct A2Block hair
Existing information.Therefore, block discovery information is the data structure of a light weight, for proving that node B receives block A1、A2。
Then, node broadcasts block A into block chain network1Block discovery information and block A2Block find information.
And work as block A3Not over verifying, node B abandons block A3。
Due to block discovery information very light weight, and quantity is few, therefore broadcasting block discovery information will not be to network
Communication band significantly influences.
Other nodes in S3, block chain network in addition to second node receive the first block and find information, as
Common recognition data source, knows together, and generates common recognition result.
Specifically, step S3 specifically includes following sub-step:
The first block that other nodes other than S31, second node receive second node broadcast finds information；
S32, the first block is found in information preservation to common recognition process；
S33, the first block being found to, information as common recognition data source, is known together using common recognition algorithm, obtains common recognition and tie
Fruit；
S34, usage threshold encryption summarize the signing messages of the first block.
Since the quantity of block discovery information is much smaller than number of transaction, the difficulty known together to block discovery information
Very little.When knowing together to block discovery information, suitable formula algorithm can be used arbitrarily and generate common recognition as a result, i.e. for common recognition
There is no special requirements for algorithm.
In addition, the signing messages of the first block is summarized using Threshold cryptosystem (threshold encryption),
It can be down to the leading rank of number of nodes, substantially reduced altogether by the data of final common recognition result by square rank of number of nodes
Know the data volume of result.
Illustratively, the node A in block chain network or node C receives the block A of Node B broadcasts1Block discovery
Information and block A2Block find information, respectively by the block discovery information preservation to common recognition process of two blocks, as
Common recognition data source.Using suitable common recognition algorithm, to the block A in node A and node C1Block discovery information know together,
And to the block A in node A and node C2Block discovery information know together, generate common recognition result.Then thresholding is used
Encryption reduces the data volume of common recognition result.
Each round common recognition is only capable of one block discovery information of common recognition for a certain block.After a wheel common recognition, even if block
A1It is not transmitted to node B or C in time, and other nodes can still know together, or even reach common understanding, it is certainly, produced
Common recognition result, it may be possible to it is incomplete, it is even empty, then continue next round common recognition in this case.
After step s 3, this method is at least further include:
S4, the transaction confirmed in result according to common recognition as a result, execution is known together.
It after result of knowing together generates, that is, can determine in this wheel common recognition, the block of which node is received by the whole network, becomes
Obtaining can not distort.Transaction in these blocks is ranked up execution according to reasonable rule, here specific sequence side
Formula can be selected according to actual scene, can prevent from currently going out interference of the block node to trading order as far as possible.
If certain node finds and do not have all blocks that common recognition result is included after common recognition result generates, friendship can be suspended
Easy execution, from the execution of continuous business after the block that other nodes obtain missing.The execution of transaction has no effect on common recognition
Process because the consistent knot of the whole network can be obtained as long as executing transaction according to established rule in the node for following correct rule
Fruit, the execution no matter traded occur when.
Illustratively, after first round common recognition, if node A and node C reaches the block discovery information of block A2
Common recognition, then show the block A in node A2Received by the whole network, becomes to distort.If node A and node C are to block A1's
Block discovery information is reached common understanding, then passes through rational sorting and execute block A1And block A2In Transaction Information.If generating
After common recognition, the discovery of C node only has block A2Without block A1, then suspend and execute block A1Corresponding transaction, by from section
Point A or B node chase after block to obtain block A1Afterwards, block A can just be continued to execute1Corresponding transaction.
The block chain transaction confirmation method based on asynchronous multichain that the present embodiment is protected, the transmission of block and know together into
The completely asynchronous progress of journey, in addition to extreme case, common recognition process will not transmission because of block and the load of block chain network it is higher
And it runs and slowly even stops；
Also, in this method due to participate in common recognition be lightweight data structure block find information, and block discovery letter
Breath is with the growth of number of nodes, and increasing degree is far below the synchronization known together based on transaction or the common recognition algorithm of weak synchronization, therefore
Based on block catenary system designed by this method, there is preferable property extending transversely.
