Description
Technical field
The present invention relates to block chain common recognition technical fields, and in particular to a kind of block chain ballot common recognition method based on equity
And system.
Background technique
Block chain common recognition mechanism is developed so far, and mainly includes proof of work (Proof Of Work, POW) mechanism, equity
(Proof Of Stake, the POS) mechanism of proof and Byzantium (Byzantine Fault Tolerance, BFT) mechanism.
Although equity proves mechanism without characteristics such as high-throughput, the low service charges of Byzantium's mechanism, in code complexity
More advantage, the carrying that is more suitable require safety and fault-tolerance high currency in degree, decentralization degree and objectivity
Function.As long as solving the problems, such as two greatest problems that equity proves mechanism itself: NaS (Nothing at Stake) and wealth
Centralization problem is distributed, relative to the proof of work mechanism of consumption mass energy and the increasingly centralization of mine pond, equity is proved
Mechanism all has great advantage, and equity proves that mechanism replaces proof of work mechanism that will become inevitable trend.
NaS problem as equity prove the problem of just existing from mechanism is born by many people think that be that not can avoid,
Relative to proof of work mechanism, since equity proves that mechanism does not need to pay high power cost, so attacker can be with
Any more competition branch of construction, and the optimal strategy of miner also becomes while competing all branches, leads to safety in this way
It is affected.But it in fact, equity proves that the competitive resource (equity total amount) of mechanism immobilizes, can not only determine unique
Main chain, but also by it is a kind of it is very convenient and fast in a manner of have the lastness characteristic that proof of work mechanism do not have.
Wealthy distribution centralization tendency is also that equity proves the inherent problem of mechanism, proves that mechanism is " rich according to equity
Person mostly " logic, after paying identical working time, the rich can be obtained more, so when the rich tend to spend more
Between work, and the poor are then on the contrary, lead to rich Geng Fu, and the poor are poorer, this process can constantly accelerate, finally as a few peoples'
" noble's game ", since Pareto rule has been deferred in wealth distribution, i.e. a few peoples know most wealth, above-mentioned " rich person
It is more " degree can be more more serious than in the imagination.
Summary of the invention
The Nas and Wealthy distribution centralization problem come for proof of work mechanism in the prior art and body tool, it is of the invention

Point is described, and the given examples are served only to explain the present invention, is not intended to limit the scope of the present invention.
The common recognition method as shown in Figure 1, a kind of block chain based on equity of the embodiment of the present invention is voted, this method comprises:
First vote trading of the Equity Investors node broadcasts in the first polling cycle；Miner's node is based on being stored in history block and divide
The block equity that goes out being fitted in the first vote trading carries out out block power competition, and competition is raw as victor to the miner's node for going out block power
At and issue new block；Victor obtains the second vote trading in the second polling cycle, based on being stored in history block
And the main chain equity being assigned in the second vote trading determines the block on main chain and fixed main chain.
During the ballot of block chain common recognition, there is no power contest is calculated, avoids high energy consumption and calculates power centralization hidden danger,
Also there is no the defects of multiple ballot and history attack；Moreover it is capable of providing enough competition intensities to guarantee network security, no
Wealthy distribution centralization and inflation can be fallen into；Finally, have the advantages such as lastness, objectivity and complete decentralization,
Special joint and overhead are not needed, so that the sustainability and scalability for digital cash lay the foundation.
As an example, first vote trading of the Equity Investors node broadcasts in the first polling cycle is specifically included: power
Beneficial people's node sends broadcast singal before transaction is initiated；The picker's node for being attached to miner's node is receiving broadcast letter
Network request is sent after number；Equity Investors node receives and responds first network request, broadcasts the first vote trading.
Exemplarily, the first vote trading may include further vote transaction and pure ballot type transactions, and further vote is handed over
Easily it can be collected and be collectively stored in any one history block with pure ballot type transactions；Further vote transaction can be logical
It crosses Equity Investors node and miner's node address affiliated by picker's node is attached to what general transaction structure obtained, miner's node
Address is as the first ballot mark that Equity Investors node is the ballot of miner's node；Pure ballot type transactions only retain the first ballot mark
Know, there is no general transaction content, block equity competes out the ballot equity of block power as miner's node out, and main chain equity is as determination
The ballot equity of main chain and the block on fixed main chain.
In the count of votes stage, wallet program goes out block equity and main chain for what the history block in the first polling cycle was stored
Equity is respectively allocated to miner's node address that Equity Investors node is voted, and indicates that miner's node obtains Equity Investors node polling station
The ballot equity got；Set is formed with all first vote tradings in the first polling cycle, set T is recorded as, from collection
The first vote trading selected after miner's node last time goes out block in T is closed, set T ' is recorded as；Statistics miner's node exists
That gets in set T ' goes out block equity, is recorded as set X；The main chain equity that statistics miner's node is got in set T, is recorded as
Set Y, set X and set Y obtain the corresponding count of votes in Equity Investors node polling station as a result, such block equity out as miner's node
Miner's node is focused on by ballot with main chain equity.
Count of votes result corresponding to any one block a moment refers to one first before the moment corresponding to block a
Statistical result in polling cycle is recorded as set XaAnd Ya, set XaAnd YaCount of votes as the first vote trading is as a result, divide
It Yong Yu not determine the victor of block power competition and determine main chain.
As an example, victor generates and issues new block and specifically includes: victor obtains out to be counted in block equity
Ticket goes out block equity to miner's node address, and miner's node address is included in the first vote trading；One is carried out with predetermined period
A Hash operation hashProof () based on calibration constant, as hashProof () < target*d*effective (x), then
Block requirement out is reached by the block equity that goes out of count of votes to miner's node address, wherein target is target, and d is difficulty adjustment parameter,
Effective (x) is for calculating by the miner's node for going out in block equity effectively to go out block equity of count of votes to miner's node address
Block excitation function out, x are to go out block equity by count of votes to miner's node address.
In order to allow the block ability that goes out of miner's node to match with ballot correctness, effective (x) is counted from set X
Effective block equity out out are as follows: the part for identical accounting of voting with the miner for being directed toward branched chain goes out block equity.
When reaching block requirement out by the block equity out of count of votes to miner's node address, first that victor is received is thrown
Ticket transaction is bundled in new block, and new block is published in network, is illustrated in figure 2 the process that victor generates new block
Schematic diagram, the first polling cycle can be 6000 block durations.
As an example, it is specific that the Hash operation hashProof () based on calibration constant is carried out with predetermined period
It include: that predetermined period is adjusted with effective first equity when the first vote trading is there are when pure ballot type transactions.
In order to control ballot frequency, need to adjust the ballot ability that account is possessed, as an example, from initial block out
Equity starts, whenever and polling booth two neighboring first vote trading between corresponding with each Equity Investors node is every increasing by one
When a chronomere, increases according to the first preset ratio and initially go out block equity, until polling booth is every increasing to the first polling cycle,
It obtains fully going out block equity, such as: chronomere is 10 block durations.
As an example, the second vote trading that victor obtains in the second polling cycle is specifically included: Suo Youkuang
Second ballot mark is periodically published in network by work node；Victor is identified the second ballot in the form of the second vote trading
It is collected into history block.
For example, the second ballot mark can be main chain top block address, victor is with the second polling cycle to main chain top
Petiolarea block address is signed and is published in network, ballot of the main chain top block address as victor to main chain, can be with
Second vote trading form is bundled in history block, such as: the second polling cycle is 60 history block durations, such as Fig. 3 institute
It is shown as the flow diagram that victor is the ballot of all branched chains.
As an example, determined based on being stored in history block and being assigned to the main chain equity in the second vote trading
Block on main chain and fixed main chain specifically includes: when the branched chain in block chain is more than the second polling cycle, with second
Branched chain is divided at least two sections of branch segmentations by polling cycle.
Statistics miner's node gets each section of the stored main chain equity of branch segmentation respectively, and each section of branch segmentation is deposited
The main chain equity of storage is averagely allocated to all second vote tradings.
Calculate separately the corresponding main chain power of the second vote trading of each section of branch segmentation where the second ballot mark is directed toward
The sum of benefit obtains the weight of each branch segmentation.
The priority of corresponding branched chain is determined based on the weight of each section of branch segmentation, the branched chain of highest priority is true
It is set to main chain.
For example, victor confirms the flow diagram of main chain as shown in Figure 4 a, compare new block b two-by-two1, new block b2、
New block b3With new block b4Priority, the wherein new block b of highest priority2The branched chain at place is main chain, in main chain
Block P is current root block, and root zone block is a specific block, other blocks generated before root zone block can not all replace
It changes, the block generated after root zone block all must be the descendants of root zone block, play the role of fixed block.
From the weight determined in the weight of main chain between new block and block to be determined, when in new block and area to be determined
When weight between block is more than default main chain equity value, block to be determined is fixed as to new root zone block.
For example, if Fig. 4 b is the flow diagram that victor confirms root zone block, new block b2For the head block of main chain, to
Determine block P1、P2And P3To new block b2Length be respectively less than the second polling cycle；Calculate separately block P to be determined1、P2And P3
To new block b2Weight, wherein block P to be determined3To new block b2Weight be more than default main chain equity value, will be to be determined
Block P3It is fixed as new root zone block, default main chain equity value can be 2/3rds of main chain equity.
As an example, after victor issues new block, further includes: victor and wallet program get the respectively
The service charge and digging mine reward of two preset ratios, the wallet program of different wallet program developers exploitations is different, this meaning
Taste the service charge got of wallet program and dig mine reward and can be used as the service charge and dig mine prize that wallet program developer is got
It encourages, such as: victor gets 14% service charge, wallet program gets 16% service charge and digging mine reward is equal to service charge
Twice.
As an example, victor and wallet program get the service charge of the second preset ratio respectively and dig mine reward
Specifically include: Equity Investors node increases the account attributes information of wallet program in the first ballot mark, such as: account attributes letter
Breath can be account identification field；
Victor gets service charge from the first vote trading that it obtains ballot；The reward of digging mine and money that victor gets
The digging mine reward that packet program is got is obtained according to network node dynamic adjustment, such as: with Equity Investors node, picker's node and mine
Work node network consisting node.

Picker's node and miner's node.
As the owner of currency, Equity Investors node is the main body of every transaction in network, because of the broadcast of every transaction
Signal is all initiated by Equity Investors, and is responsible for response first picker's node that network request is initiated to it, then certainly by it
The ballot mark of body is bundled to structure of deal and is published to network.
Picker's node is attached to each miner's node, and the Equity Investors node being responsible near detecting is collected as much as possible
Vote information can run on the network terminal in the form of being embedded in App client or web page source code.
It is that it collects vote information that miner's node, which possesses one's own picker, and it is competing to participate in out block power using vote information
Strive, verify transaction, block etc., and possess the franchise to main chain.
Equity Investors node, for broadcasting the first vote trading in the first polling cycle.
Miner's node, for based on be stored in history block and be assigned in the first vote trading go out block equity carry out
Block power competition out, miner's node of competition to block power out is as victor.
Victor for generating and issuing new block, and obtains the second vote trading in the second polling cycle, with
And it is determined on main chain and fixed main chain based on the main chain equity for being stored in history block and being assigned in the second vote trading
Block.
As an example, Equity Investors node is used for before transaction is initiated, and sends broadcast singal；It is attached to miner's node
Picker's node, for sending network request after receiving broadcast singal；Equity Investors node, for receiving and responding first
A network request broadcasts the first vote trading.
As an example, victor is specifically used for: obtaining out in block equity and goes out block by count of votes to miner's node address
Equity, miner's node address are included in the first vote trading；The Hash fortune based on calibration constant is carried out with predetermined period
It calculates hashProof (), as hashProof () < target*d*effective (x), then by count of votes to miner's node address
Block equity reaches block requirement out out, wherein target is target, and d is difficulty adjustment parameter, and effective (x) is for calculating
Block excitation function is gone out by the miner's node for going out in block equity effectively to go out block equity of count of votes to miner's node address, x is by count of votes
Go out block equity to miner's node address；When reaching block requirement out by the block equity out of count of votes to miner's node address, will obtain
The first vote trading that victor receives is bundled in new block, and new block is published in network.
As an example, victor is also used to: when the first vote trading is there are when pure ballot type transactions, effectively to go out
Block equity adjusts predetermined period.
As an example, all miner's nodes are specifically used for: periodically the second ballot mark being published in network；It obtains
Victor is specifically used for: the second ballot mark being collected into history block in the form of the second vote trading.
As an example, victor is specifically used for: when the branched chain in block chain is more than the second polling cycle, with the
Branched chain is divided at least two sections of branch segmentations by two polling cycles；Statistics miner's node is got each section of branch segmentation and is deposited respectively
The main chain equity of storage, and each section of branch is segmented stored main chain equity and is averagely allocated to all second vote tradings；Respectively
The sum of the corresponding main chain equity of the second vote trading for calculating separately each section of branch segmentation where the second ballot mark is directed toward, obtains
The weight being segmented to each branch；The priority that corresponding branched chain is determined based on the weight of each section of branch segmentation, by priority
Highest branched chain is determined as main chain；From the weight determined in the weight of main chain between new block and block to be determined；When
When weight between new block and block to be determined is more than default main chain equity value, block to be determined is fixed as to new root zone
Block.
It further include wallet program as an example, victor and wallet program get the hand of the second preset ratio respectively
Continue to pay dues and dig mine reward.
As an example, Equity Investors node increases the account attributes information of wallet program in the first ballot mark；It obtains
Victor gets service charge from the first vote trading that it obtains ballot；The reward of digging mine and wallet program that victor gets are got
Digging mine reward according to network node dynamic adjustment obtain.
