Stating application layer includes programmable currency module, programmable financial module and participant's module.
The biological identification technology includes the identification such as finger vena, palm vein, fingerprint, palmmprint, face, iris and vocal print
Technology, everyone biological characteristic is different, and the every finger interior vein blood vessel of the same person, the feature of fingerprint are all not
The same, then everyone left eye and right eye feature are different for iris, therefore biological characteristic feature with uniqueness.Because making a living
Object feature and people have natural correlation, can use biological characteristic naturally to identify the identity of people.
Biological characteristic, in different times, environment, angle be when extract, and can all have several difference.It is different
People, different finger, different eyes biological characteristic, diversity factor is generally higher than 60%；The same person, identical finger, same eye,
Different time, environment, angle extraction feature, diversity factor is generally less than 20%；Identification is being carried out using biological characteristic
When be exactly that this diversity factor is utilized.
It about the diversity factor of biological characteristic, can also be replaced with the concept of similarity, smaller this phase of meaning of diversity factor
It is bigger like spending, on the contrary diversity factor means that more greatly similarity is smaller.Diversity factor A%, when being described with the concept of similarity,
Similarity is (100-A) %.
It may be said that biological characteristic is a kind of a kind of special data for having had both uniqueness Yu randomness double grading, in block
Both characteristics of biological characteristic are utilized in catenary system.In practical applications, for every kind of biological identification technology, two can be set
The threshold value D (Different) and S (Same) of a diversity factor, diversity factor, which is more than or equal to D, indicates not to be the same biological characteristic, poor
It is the same biological characteristic that different degree, which is less than or equal to S expression,.
Application of the biological characteristic in hash function: common hash function needs a random number as input, as before
Giving an account of the content biological characteristic to continue has the characteristics that randomness, can be used as the seed for generating random number or even biological characteristic is straight
It connects and is used as random number.
When the secret key of the asymmetric encryption module generates, random number or some other data is needed to be used as input,
Using the randomness of biological characteristic, using biology sign as the input for generating asymmetric secret key, it can be ensured that each user's is close
Spoon does not repeat；And because the inherent feature that biological characteristic belongs to user's body will not lose, can be very good to carry out secret key school
It tests and prevents from forgeing and lose.
The data block module exists all in the form of encryption data, and every data has signature and verification, because
There is natural correlation for the identity of biological characteristic and user, biological characteristic is used for the encryption of data block, allows and encrypt number
According to safer；Biological characteristic is used for simultaneously the signature of block data, allows user to the operation of block data or to block counts
According to ownership have non repudiation.
In the authentication mechanism module, between each node in block chain, when carrying out network communication, need by close
The mode that spoon is negotiated establishes safe communication channel, and secret key needs to confirm the identity of other side when negotiating, traditional
Two side's Key Exchange Protocol of Diffic-Hellmen/algorithm, can suffer from internuncial attack, and secret key exchanges process wherein
The middle verifying that biological characteristic is added, has the characteristics that uniqueness and randomness using biological characteristic, can effectively prevent centre
People's attack.And in the authentication system of third party KDC trusty (Key Distribution Center), Ke Yi
It is verified when application reply secret key using biological characteristic, prevents user's secret key from being pretended to be by others to KDC application when losing and return
Secret key is talked about, to improve safety.
Preferably, described in the main PoW mechanism module of common recognition layer and using the combination of DPoS mechanism module, PoW (Proof
Of work) the huge computing resource consumption of mechanism needs, DpoS (Delegated Proof of Stake) is in computing resource
More there is advantage in terms of consumption and efficiency.
PoW mechanism, on the one hand generate block when rely on be workload (computing resource) a large amount of investment efficiency it is lower, and
And because all user nodes will participate in common recognition decision, efficiency is relatively low, its advantage is that realizing real decentralization.
DPoS knows together, and with the board of directors to vote some similar for mechanism.In a decentralization system, by policy-making power
All shareholders are distributed to, and when shareholder vote is more than 51%, then it is assumed that the decision is passed through, and the decision is irreversible.?
There is a key player to be called representative in the mechanism, representative is the node for generating block, it is desirable to first have to payment one as representative
Fixed ensuring funds come guarantee represent credibility.And user then possesses the right to elect a deputy.Each user can be with vote by ballot
One credible representative, obtains the right that the most preceding n representatives of ticket then has production block in the whole network, this n representative is held
Some polls are equivalent to the number of share of stock that the node is held.This n representative will be produced block, the block of generation in turn on schedule
By the number of share of stock be more than 51% and think that block generates and successfully represent the formality that will trade from block of one block of every generation
Income is obtained in expense.And these incomes also will be to represent the reward mechanism for maintaining to participate in online.In DPoS common recognition mechanism, representative
Reliability seems increasingly important, and when shareholder chooses and represents, shareholder can see the error rate for representing out block, so that shareholder can be with
Correctly selection represents.On the other hand, representing out block is temporally to generate in turn, therefore wrong generation one is represented when one
When block, as long as mustn't go to 51% approval, generated then the block will be represented in next period by others.It can be with
It is more efficient with PoW common recognition mechanism to say that DPoS common recognition mechanism is compared.DPoS common recognition mechanism is truly to get rid of to dig being total to for mine
Knowledge mechanism, so that entire block catenary system be allowed to be greatly lowered the consumption of computing resource with waste.
The division of labor of PoW and DPoS mechanism is, DPoS mechanism is used to need the application of efficiency, and PoW mechanism application
In the application for needing higher reliability.
And in this layer, mainly bio-identification is applied in DPoS mechanism, the purposes there are three bio-identifications in DPoS,
First, can be used for user carries out verifying authentication to user identity when electing a deputy；Second, can be when representing generation block
As the signature represented to generated block；Third, can be when other representatives vote to generated block to ballot generation
The identity of table is verified.
In DPoS mechanism, the biological characteristic of all node users must periodically update, to guarantee its credit rating or card
Its bright participation, specified time do not have more news, and the weight possessed in the ballot of block catenary system can reduce, until returning
Zero.
The issuing mechanism module gets rid of traditional by the way of digging mine, is known together mechanism based on DPoS above-mentioned, by
The representative elected generates block, including the corresponding digital cash of distribution, and using biological characteristic to the currency issued
It signs.
Including intelligent contract, it is even multi-party that generally there are the both sides of transaction, and generates among contract and nonsystematic, but
The actual participation at necessarily useful family.Therefore in the intelligent contract of this block catenary system, each side of contract must be using (label in real time
In specified time after ordering contract) biological characteristic of acquisition signs, and intelligent contract can just start to execute intelligence after the completion of signature
It can the corresponding script of contract or program.
Participant's module includes the node owner and ordinary user of block chain, using bio-identification to these users
Identity verified, reduce ordinary user's wallet in traditional block chain application and lose, the risk that password is forgotten；In addition, can
To be signed with biological characteristic to generated transaction contract etc., node distorting to data is prevented.
The present invention is divided into block catenary system multiple modules of 6 logical layers, and using human body biological characteristics and
The natural correlation of personal part and uniqueness, the randomness of human body biological characteristics, human body biological characteristics identification technology application
In the realization of each logical layer of block chain, building more safely and conveniently block catenary system, guarantee block chain data,
Under the premise of the safety of communication, its requirement to power is calculated is reduced, saves hardware resource investment and the energy that block chain needs
Consumption.
