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, specific examples are only used to explain 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:

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.

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
End 11.

7, block signature (Block Signature): agent node is using own private key to the Hash content of current block
Obtained from making signature operation, whether created by legal agent node for wallet node verification block.
The block information and random number that agent node is recorded according to block head in each miner's identity information, block, meter
When calculating the corresponding cryptographic Hash to be verified of random number, firstly, agent node determines target Hash seed, wherein any two are breathed out
Uncommon seed is all different, and each Hash seed includes at least being combined by block information, miner's identity information and random number
Component values.Secondly, agent node generates the cryptographic Hash to be verified of random number according to target Hash seed.
Agent node is according to target Hash seed, when generating the cryptographic Hash to be verified of random number, firstly, according to following combination
Relationship: Hm-2Hm-3Hm-4......H2H1H0Z is combined into m-th of Hash seed, wherein m is positive integer, Hm-1For m-th of Hash
Value, Z are the 1st Hash seed, and Z is combined by block information, miner's identity information and random number.Secondly, m-th of selection
For Hash seed as target Hash seed, m is customized by designer, for example, m can for 1 or 2 or ... or 8192 or
100000, in the present embodiment, select the 8192nd Hash seed as target Hash seed.Again, agent node is by target
Hash seed makees Hash operation, generates the cryptographic Hash H to be verified of random numberm-1。
For example, Fig. 4 a is please referred to, the 1st Hash seed is by miner's wallet address+miner's identity information+random number
(Z) it is combined into, the 1st Hash seed Z is made into Hash operation, obtains the 1st cryptographic Hash H0, remember the 1st cryptographic Hash H0For Hash#
8191。
Please refer to Fig. 4 b, the 2nd Hash seed is by the 1st cryptographic Hash+miner's wallet address+miner's identity information+random
Number (H0+ Z) it is combined into, the 2nd Hash seed is made into 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+miner's body
Part information+random number (H1+H0+ Z) it is combined into, the 3rd Hash seed is made into Hash operation, obtains the 3rd cryptographic Hash H2, note the 3rd
A cryptographic Hash H2For Hash#8189.
……
And so on, obtain the cryptographic Hash of preset quantity.
In the present embodiment, select the last one calculated cryptographic Hash of Hash seed as cryptographic Hash to be verified.
The data bits of each cryptographic Hash to be verified is 64byte, and preset quantity is 4096, that is, one shares 4096
Cryptographic Hash to be verified.When cryptographic Hash to be verified is 64byte, fairness is helped to improve, relatively weakens and calculates the strong digging of power
Absolute predominance brought by mine machine relatively improves and calculates the chance that the weaker digging mine machine of power participates in digging mine.Cause are as follows: 64byte to
To be verified cryptographic Hash of the cryptographic Hash relative to 32byte is verified, in the verifying of subsequent common recognition, improves the complexity of data calculation amount.
Since the existing calculation power for digging mine machine is more and more stronger, according to the cryptographic Hash to be verified of 32byte, calculating the strong digging mine machine of power can be real
Mine is dug to when property, and calculates the weak digging mine machine such as POS machine of power, but has not been able to rapidly dig mine and be exceeded or eliminate.However, working as
Using the cryptographic Hash to be verified of 64byte, calculating the strong digging mine machine real-time of power cannot effectively be met the requirements, then, dig mine it
Before, calculate power by force with the search space of calculating weak the diggings mine machine of power and all construct in advance random number, at this point, due to not starting also to dig mine, calculation
Power by force with calculate the weak digging mine machine of power and do not embody significant difference also.When Deng digging mine, due to be verified in the search space of random number
Cryptographic Hash is all ready for, and is calculated power and is insignificantly dug mine efficiency with calculating the weak digging mine machine of power and can reach difference by force, thus phase
Over the ground, 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 agent node, in some embodiments, agent node is according to following syntagmatic:
Hm-2Hm-3Hm-4......H2H1H0Z is combined into m-th of Hash seed.For example, agent node judges first
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......H2H1H0It sorts in Z in the data conduct of the presetting digit capacity of forefront
M-th of Hash seed；
If being less than, H is selectedm-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.
S33, the corresponding cryptographic Hash to be verified of random number is sent to miner's node, so that miner's node is according to Hash to be verified
Value and target cryptographic Hash, are packaged block.
The verification mode for verifying current block is varied, for example: when miner's node verification current block, firstly,
Cryptographic Hash to be verified and generation signature are made into Hash operation, obtain expectation cryptographic Hash.Due to generating signature in block catenary system
With uniqueness and consistency, the randomness of cryptographic Hash to be verified is relatively high originally, subsequent recyclings generate sign with it is to be verified
Cryptographic Hash makees Hash operation, to improve randomness again, reduces the probability that miner's node makees repeatability verifying work.Secondly,
Miner's node judges it is expected that whether cryptographic Hash is less than target cryptographic Hash；If being less than, the corresponding random number of cryptographic Hash to be verified is determined
To be effective, and it is packaged block；If more than determining that the corresponding random number of cryptographic Hash to be verified is invalid.
In some embodiments, some strong digging mine machines of power of calculating can be completed in real time without the cooperation of agent node
S31 to S32, to be packaged block, it is clear that the weak digging mine machine of calculation power is not able to the competition strong with power is calculated and goes down.In order to improve digging mine
Fairness so that some POS machine etc. are calculated the weak digging mine machine of power and are added and dig mine task, in some embodiments, Dai Lijie
Point generates block data according to the corresponding cryptographic Hash to be verified of random number.Secondly, agent node also makees at signature block data
Reason.Again, the block data after agent node sends signature to miner's node, so that when verifying signature is legal, Kuang Gongjie
Point is packaged block according to cryptographic Hash to be verified and target cryptographic Hash.Therefore, miner's node needs to verify the signer of agent node
