Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, the specific embodiments are only for explaining the present invention, not
For limiting the present invention.
Block catenary system has the characteristics that decentralization, is different from conventional center server, since block catenary system does not have
There is centralization node, the mechanism that needs to know together maintains normal operation, for example, common recognition mechanism includes POW algorithm, it is based on POW algorithm,
Block catenary system can be realized the common recognition verifying of block.
POW algorithm is a kind of strategy of a kind of reply Denial of Service attack and other service abuses, a proof of work
Refer to that a data for meeting specified conditions calculate, it is relatively difficult to generate correct result, but it is simpler to verify correct result
It is single.The generation of correct result can only carry out verifying trial and error by constantly enumerating random number, to eventually find correct option.
Wherein, which realized using Hash (hash) algorithm.Hash algorithm is a kind of one-way Hash algorithm, calculates Kazakhstan
The process of uncommon value is fairly simple, but inversely to obtain initial data according to fixed cryptographic Hash, then can only by enumerate trial and error come
It carries out.
In some virtual encryption money-systems, when carrying out random hash operation, POW algorithm is introduced to some spy
The scanning work of definite value, for example, at SHA-256, random hash value with one or more 0 start, with 0 quantity gradually
Increase, traversing out workload required for solution corresponding with the random hash value in the case of this will be exponentially increased, and to result
It tests, only needs a random hash operation.
A random number (Nonce) is augmented in the block of some virtual encryption money-systems, which needs to meet
So that there is the condition of required specified quantity 0 in the cryptographic Hash of given block.It, can only due to the irreversible property of Hash operation
The random number of the condition of satisfaction is traversed out by making repeated attempts.
As long as block chain node traverses go out to meet the random number of condition, which just completes the card of workload
It is bright, to obtain the packing book keeping operation power of block.
In the following, the embodiment of the present invention elaborates the common recognition verifying process of traditional virtual encryption money-system.It is as described below:
1, Transaction Information is collected and selected to block chain link point, and calculates Merkel (Merkle) root Hash of transaction List Table
Value.
2, block chain node tectonic province build, wherein block head includes version, the cryptographic Hash of upper block head, Merkel
Root cryptographic Hash, timestamp (timestamp), difficulty value (difficulty) and random number.
3, block chain node calculates the block head cryptographic Hash of construction, and whether test zone build cryptographic Hash is less than or equal to target
Value.If so, completing proof of work, the block of packing is broadcasted into the whole network, other block chain nodes in block chain will be examined
Survey the legitimacy of the block.If it is not, then returning to step 2, continue workload computing.
The block chain node for executing above-mentioned process can also be known as miner's node.
Firstly, since each block chain node in the whole network needs to obtain the packing book keeping operation of block by proof of work
Power, therefore when using POW common recognition mechanism, each miner's node requires to constantly generate random number to be examined with trial and error, with this time
Suitable random number is gone through out, which needs a large amount of electric power support, to cause a large amount of energy waste.
Secondly as independently carrying out proof of work calculating between each miner's node, there are biggish for working space
It repeats, so as to cause in the identical situation of difficulty value, the time needed for miner's node completes workload is long, out block low efficiency
Under.
In fact, riseing with the encryption money price in virtual encryption money-system, people dig mine by improvement and set
It is standby, to realize the block out of higher efficiency, for example, from using CPU (Central Processing Unit, central processing unit) to dig
Mine digs mine to using GPU (Graphics Processing Unit, graphics processor), then arrives FPGA (Field
Programmable Gate Array, field programmable gate array) dig mine, the ASIC of the customization finally occurred
(Application Specific Integrated Circuit, specific integrated circuit) digs mine.
It digs mine calculation power exponentially to increase every year, since some virtual encryption money-systems can be adjusted according to power dynamic is calculated
Therefore whole digging mine disaster angle value increases, difficulty value is also increased with exponential with power is calculated.It is such to increase so that independent miner digs
Mine can not obtain income, therefore there has been the appearance in mine pond.Miner's node is combined together by mine pond by certain agreement,
It concentrates and calculates power progress workload computing, obtain and the miner to work in mine pond is given into reward after rewarding.
There are mine pond administrator, mine pond administrator is responsible for coordinating and managing all miner's work in mine pond.Therefore, mine pond administrator
Customized related protocol is needed, is communicated with miner.At the same time, miner administrator is responsible for being packaged transaction, distributes for miner
Related work amount, therefore, the relevant reward of system also can all be sent to mine pond administrator, and mine pond administrator is responsible for mine
Work sends the reward of related work amount.It is also easier to complete for independent miner since mine pond summarizes a large amount of power of calculating
Proof of work and obtain system award, this makes the income of miner that can become relatively stable, and mine pond administrator can be with
Obtain its certain mine pond management return.
In the following, combination of embodiment of the present invention Fig. 1 elaborates the common recognition verifying process of traditional virtual encryption money-system.Such as
It is lower described:
1, miner's client 11 sends common recognition instruction to management server 12, wherein common recognition instruction includes miner's client
11 identity information, operation information and relevant parameter information, parameter information specify dbase and the version number of miner's client.
2, after management server 12 receives this information, information can be confirmed, after confirming successfully, returns to relevant information.
3, miner's client 11 sends authentication information, and authentication information includes the wallet address of miner's client 11.
4, the legitimacy of 12 authentication verification information of management server, after being verified, it is logical that management server 12 returns to verifying
Cross information.
5, management server 12 sends difficulty setting information to miner's client 11.
6, management server 12 is by sending the block information that carry out proof of work to miner's client 11.
7, the common recognition of miner's client 11 verifying block will when miner's client 11 traverses out the random number of the condition of satisfaction
The random number is sent to management server 12.
8, management server 12 verifies the random number that miner's client 11 provides, and transmits verification result to miner client

Uncommon value is all different.
In the present embodiment, the verification mode for verifying current block is varied, for example: the verifying of agent node 21 is worked as
When preceding block, firstly, cryptographic Hash to be verified and generation signature are made Hash operation, expectation cryptographic Hash is obtained.It signs due to generating
There is uniqueness and consistency in block catenary system, the randomness of cryptographic Hash to be verified is relatively high originally, subsequent recycling life
Make Hash operation with cryptographic Hash to be verified at signature, to improve randomness again, reduces agent node 21 and make repeated verifying
The probability of work.Secondly, agent node 21 judges it is expected that whether cryptographic Hash is less than or equal to the target cryptographic Hash；If be less than or
It is equal to, determines that the corresponding random number of cryptographic Hash to be verified is effective, and be packaged block；If more than determining cryptographic Hash to be verified
Corresponding random number is invalid.
In summary, on the one hand, since the corresponding cryptographic Hash to be verified of same search number is all different, Dai Lijie
Point can be to avoid same verifying work be repeated, to relatively save energy consumption.On the other hand, since miner's node is pre-
There is the cryptographic Hash to be verified of each random number, agent node is without expending a large amount of Kazakhstan to be verified calculated power and calculate each random number
Uncommon value, it is only necessary to lower calculation power can be completed to dig miner's work, therefore, can satisfy the low equipment of calculation power and participate in digging mine,
Universality is improved, makees to become more fair so that digging miner.

Modulo4096 is calculated, and obtains specified search number, for example, obtained search number is scoop11 or scoop403 etc..
Then, as previously mentioned, agent node 21 is sent to each miner's node digs mine task requests, wherein the digging mine task requests are taken
Band search number scoop11, it is scoop11 that each miner's node, which searches out search number in the search space of each random number,
Corresponding cryptographic Hash to be verified, such as: for miner node a, search number is scoop11 in the search space of random number A1
Corresponding cryptographic Hash to be verified is X1, and search number is to be verified corresponding to scoop11 in the search space of random number A2
Cryptographic Hash is X2, and it is X3 ... that search number, which is cryptographic Hash to be verified corresponding to scoop11, in the search space of random number A3.
It is Y1 that for miner node b, in the search space of random number B1, search number, which is cryptographic Hash to be verified corresponding to scoop11,
It is Y2, the search of random number B3 that search number, which is cryptographic Hash to be verified corresponding to scoop11, in the search space of random number B2
It is Y3 ... that search number, which is cryptographic Hash to be verified corresponding to scoop11, in space.
As previously mentioned, when digging mine, what the search space of each random number can be pre-generated, miner can be based on
The search space of wallet address and each random number of generating random number.In some embodiments, each miner's node is all corresponding with
Miner's wallet address, also, each miner's wallet address is all different.Therefore, first when generating the search space of each random number
First, miner's node 22 determines the corresponding Hash seed of each cryptographic Hash to be verified, wherein any two cryptographic Hash to be verified is corresponding
Hash seed it is all different, each Hash seed includes the component values being at least combined by miner's wallet address and random number.
Secondly, miner's node 22 generates the cryptographic Hash to be verified of random number according to each Hash seed.As previously mentioned, each random number
The data of generation are divided into 4096 data spaces, and each data space size is 64byte, each data storage
Cryptographic Hash to be verified in space is made of two 32byte cryptographic Hash, and therefore, each random number can correspond to 8192 32byte
Cryptographic Hash.If each cryptographic Hash to be verified is 32byte, one shares 8192 cryptographic Hash to be verified.If each Hash to be verified
When value is 64byte, one shares 4096 cryptographic Hash to be verified.Again, miner's node 22 is each Hash values match pair to be verified
The search number answered, to generate the search space of random number, for example, being for first Hash values match search number to be verified
Scoop0, is Scoop1 for second Hash values match search number to be verified, and third Hash values match search to be verified is compiled
Number be Scoop2 ....And so on, obtain 4096 or 8192 cryptographic Hash to be verified.
When miner's node 22 generates the cryptographic Hash to be verified of random number according to each Hash seed, firstly, it is according to following
Syntagmatic: Hm-2Hm-3Hm-4......H2H1H0Z is combined into m-th of Hash seed, wherein m is positive integer, Hm-1It is m-th
Cryptographic Hash, Z are the 1st Hash seed, and Z is combined by miner's wallet address and random number.Secondly, miner's node 22 is by Hash
Seed makees Hash operation, generates cryptographic Hash Hm-1.Again, any two cryptographic Hash is combined into the random number by miner's node 22
Cryptographic Hash to be verified.
For example, Fig. 4 a is please referred to, the 1st Hash seed is combined by miner's wallet address+random number (Z), by the 1st
A Hash seed Z makees Hash operation, obtains the 1st cryptographic Hash H0, remember the 1st cryptographic Hash H0For Hash#8191.
Fig. 4 b is please referred to, the 2nd Hash seed is by the 1st cryptographic Hash+miner's wallet address+random number (H0+ Z) combination
At the 2nd Hash seed is made Hash operation, obtains the 2nd cryptographic Hash H1, remember the 2nd cryptographic Hash H1For Hash#8190.
Fig. 4 c is please referred to, the 3rd Hash seed is by 1 cryptographic Hash of the 2nd cryptographic Hash+the+miner's wallet address+random number
(H1+H0+ Z) it is combined into, the 3rd Hash seed is made into Hash operation, obtains the 3rd cryptographic Hash H2, remember the 3rd cryptographic Hash H2For
Hash#8189。
……
And so on, obtain the cryptographic Hash of preset quantity.
As previously mentioned, if one shares 8192 cryptographic Hash to be verified when each cryptographic Hash to be verified is 32byte.If each
When cryptographic Hash to be verified is 64byte, one shares 4096 cryptographic Hash to be verified.When cryptographic Hash to be verified is 64byte, have
Help improve fairness, relatively weaken and calculate absolute predominance brought by the strong digging mine machine of power, it is weaker to relatively improve calculation power
Dig the chance that mine machine participates in digging mine.Cause are as follows: to be verified cryptographic Hash of the cryptographic Hash to be verified of 64byte relative to 32byte, rear
When continuous common recognition verifying, the complexity of data calculation amount is improved.Since the existing calculation power for digging mine machine is more and more stronger, according to 32byte
Cryptographic Hash to be verified, mine can be dug to real-time by calculating the strong digging mine machine of power, and calculate the weak digging mine machine such as POS machine of power, but not
Mine rapidly can be dug and be exceeded or eliminate.However, it is real to calculate the strong digging mine machine of power when the cryptographic Hash to be verified using 64byte
When property cannot effectively be met the requirements, then, before digging mine, calculate power by force with calculate the weak digging mine machine of power and all construct random number in advance
Search space, at this point, due to not starting also to dig mine, calculate power by force with calculate the weak digging mine machine of power and do not embody significant difference also.Deng
When digging mine, since cryptographic Hash to be verified in the search space of random number is all ready for, calculate power by force with calculate the weak digging mine machine of power all
Difference can be reached and insignificantly dig mine efficiency, so that relatively, digging mine can be participated in by calculating the weak digging mine machine of power.
As previously mentioned, next Hash seed is that constantly group closes a Hash to be verified on the basis of upper Hash seed
Value, then, the data volume of Hash seed the more is rolled the more big.When the data volume of Hash seed is excessive, the meter of miner's node can be reduced
Calculate efficiency.In order to improve the computational efficiency of miner's node, in some embodiments, miner's node 22 is according to following syntagmatic:
Hm-2Hm-3Hm-4......H2H1H0Z, during being combined into m-th of Hash seed, miner's node 22 judges Hm- 2Hm-3Hm-4......H2H1H0Whether the data bits of Z is greater than presetting digit capacity threshold value；If more than selection is in Hm-2Hm- 3Hm-4......H2H1H0Sequence is in the data of the presetting digit capacity of forefront as m-th of Hash seed in Z；If being less than, selection
Hm-2Hm-3Hm-4......H2H1H0Z is as m-th of Hash seed.
For example: when the data bits of Hash seed has been over 4096byte, later step is adopted when calculating
Hash seed is selected at Hm-2Hm-3Hm-4......H2H1H0It is sorted in Z in the data of the presetting digit capacity of forefront, wherein
The presetting digit capacity is 4096byte.Therefore, the maximum data digit of each Hash seed is not exceed 4096byte.
In some embodiments, any two cryptographic Hash is combined into the cryptographic Hash to be verified of random number by miner's node 22
When, according to following syntagmatic:
[H0Hm-1,H2Hm-3,H4Hm-5,......Hm-6H5,Hm-4H3,Hm-2H1],
Every two cryptographic Hash to be verified is combined, to form the cryptographic Hash to be verified of random number, wherein m is even number.Also,
Miner's node 22 is the corresponding search number of each Hash values match to be verified, to generate the search space of random number.
For example: please refer to Fig. 4 d, miner's node 22 by " Hash#0 " and " Hash#8191 " be combined into first it is to be tested

In order to illustrate the embodiment of the present invention in further detail, digging mine main flow provided in an embodiment of the present invention is hereafter summarized.
It is understood that the protection scope that digging mine main flow hereafter is not intended to restrict the invention, is only intended to aid in illustrating
The embodiment of the present invention.It is as described below:
1, miner's node 22 is sent to agent node 21 digs mine request.
It digs mine request and is used to indicate addition digging mine.Dig mine request with carrying the equipment Serial Number for digging mine machine and miner's wallet
Location.
2, mine request is dug in the verifying of agent node 21, and issues verification result to miner's node 22.
After being verified, miner's node 22 can be added in current mine pond by agent node 21 automatically.
3, when starting a new block digging mine, transaction record is first packaged into block by agent node 21, and according to area
Block number includes: that target cryptographic Hash and search are numbered according to necessary parameter, necessary parameter is calculated.
Herein, when agent node 21 calculates search number, process specific as follows:
A, 32byte is generated signature by agent node 21 and 8byte block elevation information is combined and does Hash operation,
32byte GenHash is obtained, as shown in figure 4g.
B, 32byte GenHash progress modulo 4096 is calculated, obtains specifying search for numbering, as shown in figure 4h.
4, agent node 21 by new block essential information and specify search for number be assembled into dig mine task requests, be broadcast to
All miner's nodes 22 in mine pond.
5, miner is according to specifying search for numbering, by the cryptographic Hash to be verified stored in search space (by two 32byte groups
The 64byte data of synthesis) it is combined into pair with random number, it is uploaded to agent node 21 one by one.
6, agent node 21 often receives the cryptographic Hash to be verified of miner's node 22 upload, can be first to miner's node 22
Workload (this digs the quantity that mine uploads cryptographic Hash to be verified) adds up, and verifies to cryptographic Hash to be verified.
Herein, verification process is as follows:
A, after agent node 21 receives the cryptographic Hash to be verified of 64byte, by the cryptographic Hash to be verified and 32byte of 64byte
Generation signature combine carry out Hash operation, obtain Hash result (Target), as shown in figure 4i.
B, Hash result (Target) and target cryptographic Hash (Base Target) are compared, if Hash result is small
In target cryptographic Hash, indicate that the random number uploaded is effective, agent node 21 stops this wheel and digs mine, and starts to be packaged block.
When verifying block, agent node 21 can also complete following processes:
C, check that upper a block for reference whether there is and effectively.
D, check whether the timestamp of block is later than the timestamp of a block, and earlier than following 2 hours.
E, check whether each transaction in block below transaction List Table is effective.
F, check whether the signature of block is effective using fixed public key.
G, check whether common recognition mechanism is effective.
If after 7, being verified, agent node 21 can first notify all miner's nodes 22 to stop uploading data, then completion
Block information, comprising: wallet address, Nonce, Timestamp, block signature etc..
8, generated block data is broadcast in block catenary system by agent node 21.
9, agent node 21 is divided in portion new block and obtains according to amount of work and the workload of every miner's node
Reward.
10, agent node 21 begins preparing the digging mine of next block.
In above-mentioned each embodiment, as previously mentioned, the mode that agent node 21 verifies current block is varied, and
And a random number corresponds to N number of difference cryptographic Hash to be verified, search number is obtained by known constant M to be made to the modulo operation of N
It arrives.Be with verification mode difference described in above-mentioned each embodiment: known constant M is that will combine block information to make Hash
What operation obtained, wherein the block of block information, current block that combination block information is recorded by block head in current block is high
Degree information and start dig mine ageing at.Relative to the combination block information in above-mentioned each embodiment, the present embodiment
Combination block information, which has increased newly, to be started to dig the mine time.
Agent node 21 is according to cryptographic Hash to be verified, current when having not been able to be verified during verifying current block
When block, block catenary system is the failure to enough smoothly go out block.In order to guarantee that block catenary system can smoothly go out block, pass through utilization
The changeability for starting to dig the mine time abandons current block when having not been able to output block according to currently assigned search number, and
Again mine is dug, is redefined with this and starts to dig the mine time.It is associated with due to specifying search for number with block information is combined, combines block
Information by block information, current block block elevation information and dig mine ageing at, agent node 21 is dug again
When mine, block information, the block elevation information of current block are all identical as the block of last time digging mine failure, but the beginning of the two
The digging mine time is different, and then, when digging mine again, the calculated number that specifies search for of agent node 21 is lost with last digging mine
The number that specifies search for lost is different, and in this manner, can guarantee smoothly to go out block.
For example: agent node 21 is according to cryptographic Hash to be verified, during verifying current block, firstly, agency's section
Cryptographic Hash to be verified and generation signature are made Hash operation by point 21, obtain expectation cryptographic Hash.Secondly, the judgement expectation of agent node 21
Whether cryptographic Hash is less than or equal to target cryptographic Hash；If being less than or equal to, determine that the corresponding random number of cryptographic Hash to be verified is to have
Effect, and it is packaged block；If more than, determine the corresponding random number of cryptographic Hash to be verified be it is invalid, dig mine again, and update
Start to dig the mine time, so as to reconfigure out new combination block information.Then, agent node 21 is by new combination block information
New known constant M is obtained as Hash operation, then new known constant M is made newly to specify search for obtained from the modulo operation of N
Number.
In general, in this manner, it can guarantee that block catenary system smoothly goes out block.
Be with the difference of above-mentioned each embodiment verification mode: agent node 21 is according to cryptographic Hash to be verified, verifying
During current block, firstly, agent node 21 by each cryptographic Hash to be verified divided by target cryptographic Hash, obtain with each to
Verify the corresponding deadline (deadline) of cryptographic Hash.Secondly, agent node 21 obtains generation time of a upper block and works as
The preceding time difference dug between the mine time.Again, agent node 21 works as proparea according to deadline and time difference, common recognition verifying
Block, for example, agent node 21 traverse out minimum cut from several deadlines corresponding with each cryptographic Hash to be verified
The only time, judge whether time difference is greater than minimum deadline；If it is not, determining that the corresponding random number of cryptographic Hash to be verified is nothing
Effect, and current block to be verified is waited, until being packaged current block when time difference is greater than minimum deadline；If so, really
It is effective for determining the corresponding random number of cryptographic Hash to be verified, and is packaged current block.
For example: cryptographic Hash A to be verified corresponds to deadline t1, and cryptographic Hash b to be verified corresponds to deadline t2, to be tested
Card cryptographic Hash c corresponds to deadline t3, wherein t1 is less than t2, and t2 is less than t3.At this point, agent node 21 records Hash to be verified
Value A corresponding deadline is minimum deadline t1.Herein, a upper block is to sort to correspond to block height in currently digging mine
Front, a upper block are known together, it is assumed that the current block height for digging the corresponding block of mine is the 10000th, then a upper area
The block height of block is the 9999th.The generation time for enabling a upper block is ts.When agent node digs mine every time, all detection is current
Dig the mine time, wherein the current digging mine time is variable.Enabling the current digging mine time is tp1, then time difference Δ t0=tp1-
ts.If Δ t0 is less than t1, agent node 21 switches to standby mode, that is, waits current block to be verified, and the time of waiting is always
Continue to that the new current new time difference Δ t1 for digging mine time tp2 and ts is greater than t1, is just verified and is packaged current block.If
Δ t0 is greater than t1, is verified and is packaged current block.
In some embodiments, agent node continues to update minimum deadline, for example, with the progress of verification process,
If agent node is found compared to smaller deadline minimum deadline has been recorded, agent node updates and prestores the phase
Than in having recorded smaller deadline minimum deadline and as new minimum deadline.Specifically, agency's section
Point is during verifying cryptographic Hash to be verified, firstly, agent node verifies whether the deadline that current Hash calculation goes out meets
Block requirement out, if satisfied, going out block immediately；If not meeting, the deadline that current Hash calculation goes out and the minimum prestored are judged
The size of both deadlines acts on behalf of section if the deadline that current Hash calculation goes out is less than the minimum deadline prestored
Point continues to update and prestore this compared to having recorded minimum deadline smaller deadline and cut as new minimum
The only time.
Secondly, agent node judges whether current time difference is greater than the minimum deadline prestored, if more than then going out
Block；If being less than, continue to verify subsequent cryptographic Hash to be verified.After institute's cryptographic Hash still to be tested has been verified, block catenary system
Also fail to enough go out block, then block catenary system cuts standby mode, etc. after current times difference is greater than minimum deadline, start to beat
Wrap out block.
In this manner, on the one hand, it can guarantee that block catenary system smoothly goes out block.On the other hand, it can adjust
Block catenary system goes out the speed of block.
