Description
Technical field
The present invention relates to block chain common recognition mechanism technical fields, and in particular to a kind of to be suitable for knowledge production based on bilateral card
Weigh the intelligent common recognition mechanism of alliance's chain.
Background technique
Block chain technology is having by multiple technologies such as cryptography, point to point network communication, common recognition mechanism, intelligent contracts
Effect combination constructs the new distribution type computing architecture of data storage, circulation and processing, ensures not by third party intermediary
Under the conditions of credit endorsement, being not easy to distort, being not easy the purpose of forging, can be traced, can audit for data is realized.Currently, according to participation
The difference of mode, block chain deployment form are generally divided into publicly-owned chain, alliance's chain and privately owned chain.Publicly-owned chain is truly complete
The block chain of full decentralization, any user for possessing Net-connected computer in the whole world can be added at any time, arbitrarily read
Block information, transmission Transaction Information and transaction can obtain effectively confirmation, participate in common recognition process.Alliance's chain has mechanism of permitting the entrance
Multicenter block chain forms the relevant alliance of interests by several mechanisms and participates in and safeguard jointly, and common recognition process by choosing in advance
Node control, other nodes can participate in business but keep aloof from accounting procedure.Privately owned chain refers to the write-in permission of each node
Only by some mechanism controls, and read a kind of limited block chain that the visual demand of permission is selectively opened to the outside world, common recognition and
Verifying is strictly limited in privately owned facility-wide.
Common recognition mechanism on block chain mainly solves the problems, such as that whom is constructed block by and how to safeguard that block chain is unified.
Publicly-owned chain is reached common understanding in the network environment of mutual mistrust by cryptography and economic incentives, guarantee, and center is gone in realization completely
The credit mechanism of change.The common recognition mechanism of publicly-owned chain needs economic incentives to reward the node for participating in common recognition process.Alliance's chain node
Quantity it is generally known that the node for participating in common recognition is usually chosen in advance, thus simpler, more efficient can be total to using designing
Know algorithm.The node that book keeping operation is participated in privately owned chain is essentially all to belong to some in-house node, be not necessarily required to pass through through
Ji reward is to motivate each node to keep accounts.Currently, the widely used common recognition mechanism of block chain industry is PoW (Proof Of
Work, proof of work) algorithm, PoS (Proof Of Stack, equity prove) algorithm, Casper algorithm, DPoS
(Delegated Proof Of Stack, authorization equity prove) algorithm, PBFT (Practical Byzantine Fault
Tolerance, practical Byzantine failure tolerance) algorithm, Paxos algorithm and Raft algorithm.Publicly-owned chain generallys use PoW, PoS, DPoS
With the common recognition algorithm such as Casper, and alliance's chain and privately owned chain generally use PBFT algorithm, Paxos algorithm and Raft algorithm.Below
The basic thought for first explaining these common recognition algorithms, then points out its disadvantage.
PoW algorithm: i.e. proof of work mechanism.Node is weighed by calculating the numerical solution contention book keeping operation of random Harsh hash,
Acquire correct numerical solution with the ability for generating block be node calculate power specific manifestation.Proof of work mechanism has goes completely
The advantages of centralization, in the block chain for taking proof of work mechanism as common recognition, node can be freed in and out, and be that a kind of cope with is refused
The economic measure of exhausted service attack and other service abuses.Well known bit coin network just applies proof of work mechanism
To produce new currency.
PoS algorithm: i.e. equity proves mechanism.A certain amount of calculating work is different, and equity proves from requiring reference to execute
It is required that reference provides the ownership of certain amount encryption currency.Possess ratio and the time of token according to each node,
The digging mine disaster degree of node is reduced according to algorithm equal proportion, to accelerate the speed for finding random number.This common recognition mechanism can
Reached common understanding the required time with shortening, but substantially carries out digging mine operation there is still a need for the node in network.
DPoS algorithm: i.e. Authorized Stock proves mechanism.All node votes enumerate a certain number of node on behalf, by him
Act on behalf of all nodes confirmation block and maintain system order operation.Meanwhile all nodes in block chain have stop at any time
Exempt from and appoint the power represented.If necessary, all nodes can allow incumbent node on behalf to lose qualifications of a representative by ballot, weight
New representative is newly elected, realizes real-time democracy.Share authorisation verification mechanism can be substantially reduced participation verifying and accounting nodes
Quantity, thus reach the second grade common recognition verifying.
Casper algorithm: one kind of PoS algorithm.The common recognition of Casper is reached by block, such rather than common PoS
Reach by chain.Its basic ideas is that anyone, which mortgages enough ether coin, can participate in digging as miner into system
Mine process.Different from traditional PoS, Casper has penalty mechanism, and common recognition algorithm requires all miner's honesty to work, if one
A miner destroys purposely, does not abide by the agreement, and system will make punishment to miner: the ether coin mortgaged before confiscating.
Paxos algorithm: the common recognition mechanism based on election leadership person.It is a kind of based on message transmission and with Error Tolerance
The consistency algorithm of characteristic.As long as available more than the node of half in system, then system is integrally available, and can guarantee
The strong consistency of data.
PBFT algorithm: i.e. practical Byzantine failure tolerance mechanism.It is used to solve original Byzantine failure tolerance efficiency of algorithm not high
Problem, so that Byzantine failure tolerance algorithm becomes feasible in real system application.Similar with Paxos, it is also that a kind of use is permitted
It can vote, the minority is subordinate to the majority carrys out the common recognition mechanism that election leadership person keeps accounts.The common recognition mechanism allows strong supervisory node to join
And have authority classification ability, performance is higher, consumes energy lower, and the every wheel of the algorithm, which is kept accounts, all can elect jointly neck by the whole network node
The person of leading allows 33% node to do evil, fault-tolerance 33%.
Raft algorithm: Raft algorithm is applied to alliance's chain, more efficient relative to Paxos and PBFT algorithm.Raft be by
The distributed consensus algorithm of Stanford publication more focuses on the comprehensibility and landing of agreement from Paxos algorithm improvement
Property, its main feature is that any moment at most only has 1 legal Leader, fault-tolerance 50%.
The major defect of above-mentioned each algorithm is as follows.
PoW algorithm: relying on machine and perform mathematical calculations to obtain book keeping operation power, resource consumption is high compared to other common recognition mechanism,
Can be supervisory weak, while reaching common understanding the whole network is needed to participate in operation jointly every time, effectiveness of performance is relatively low, the confirmation common recognition of block
The period reached is longer, is not suitable for business application, allows 50% node of the whole network to malfunction in terms of fault-tolerance.Power centralization is calculated to make
PoW slowly deviate from original decentralization track.
PoS algorithm: PoW is compared, reduces mathematical operation bring resource consumption to a certain degree, performance has also obtained accordingly
It is promoted, but is still the mode for competing based on Hash operation and obtaining book keeping operation power, it can be supervisory weak.The common recognition mechanism fault-tolerance and
PoW is identical.Realize complex, intermediate steps are more, are easy to produce security breaches, and network flow pressure is big.It is more to hold coin
People can obtain the reward of more coin, to increase gap between the rich and the poor, it is final generate be more than 50% centralization node, passive evolution
For the result of unexpected centralization.
DPoS algorithm: being that node elects several agents with the main distinction of PoS, verified by agent and kept accounts,
It is similar to PoS to close rule supervision, performance, resource consumption and fault-tolerance.Realize complex, intermediate steps are more, are easy to produce peace
Full loophole.
Paxos algorithm: the general wired lower mechanism of permitting the entrance of all nodes, but node of doing evil is not allow in election process, no
Has fault-tolerance, algorithm indigestion, Project Realization are more difficult.
PBFT algorithm: three phases are reached common understanding probably due to failing and repeating；When there are 1/3 or more on block chain
When Byzantine fault node, system can not provide service；The public credibility of PBFT is insufficient.
Raft algorithm: Raft algorithm is one of Paxos algorithm and simplifies and realize, close rule supervision, performance, resource consumption and
Fault-tolerance is similar to Paxos.Raft scheme there is a problem of following: election common recognition node does not consider the block height of block chain；
It elects a common recognition node and thus node is persistently kept accounts, fault-tolerance is poor；It is inadequate to the supervision of common recognition node, it can not achieve altogether
Know being dynamically added for node to exit.
It can be seen that be directed to alliance's chain at present, also lack it is a kind of flexibly and effectively, can motivate community users, use for reference
Publicly-owned chain common recognition thought, can reach in terms of consistency, subregion fault-tolerance and availability three it is comprehensive it is optimal, can be supervisory
Good, the common recognition mechanism high-efficient, public credibility is high of knowing together.
Summary of the invention
In order to overcome the shortcomings of above-mentioned existing alliance's chain common recognition mechanism, the present invention proposes a kind of to be suitable for based on bilateral card
The intelligent common recognition mechanism of intellectual property alliance chain.
Based on the intelligent common recognition mechanism suitable for intellectual property alliance chain of bilateral card, using the logical card of equity and the logical card of circulation
Two kinds of logical cards；
Wherein,
The logical card of equity be used to motivate user participates in community activity, IP transaction is initiated and implemented in reward IP uploader, payment or

The logical card of circulation is linked up with IP true value, for embodying the IP value that user possesses.
The intelligence common recognition mechanism provides equity logical card reward: the upload of IP for following behaviors；Successfully complete demand initiation
The requirement of side, such as wanting to buy for some IP；IP is evaluated；Report bad IP；It is timely completed great IP transaction etc..
The independent logical card of circulation can not carry out external exchange.
Alliance's platform chain generates that equity is logical to be demonstrate,proved and by certain logical card of rule reward equity according to certain rule, and user can also be with
Pass through alliance's platform chain logical card of franc purchase right benefit.
Transaction refers to the primary dealing or authorization of IP, and a batch transaction in nearest a period of time will be beaten according to common recognition mechanism
Packet generates new block, is linked on block chain, and notify the whole network.
Intelligence common recognition mechanism, including user, community, node, common recognition node, intelligent contract, logical card, transaction, block, wherein
User refers to participating in the register account number of intellectual property transaction, and community refers to being known by all users, alliance's foundation and alliance
Know the group of the compositions such as the property right committee, node refers to the computer of access alliance's chain network, and intelligent contract is a set of with number
The promise of word formal definition can execute the agreement of these promises including contract participant above.It is to operate in block chain
On one section of code, and can the execution when block chain detects certain trigger conditions, node includes system node, common full section
Point and ordinary user, system node are the generally acknowledged trusted nodes of alliance, and common full node is the credible honest node of authorization, system
Node and common full node are all common recognition nodes, and there is book keeping operation power and block to generate power；Ordinary user weighs without book keeping operation, but can read
Take block chain data.
Specifically comprise the following steps:
Step 1: the calculating of participation and equity weight
The step has merged PoS algorithm and PoP algorithm, hands over according to the quantity for the logical card that circulates in equity, that is, user account with accumulative
Easy volume, to win the reward of book keeping operation power；According to the quantity and accumulative participation activity frequency of the logical card of equity in participation, that is, user account
It is secondary, to win the reward of book keeping operation power；If the PoS weight of two nodes is close, the more node of PoP weight then more has
Book keeping operation power reward may be obtained；
Step 2: common recognition calculates
The step for mainly determined by PBS (system node verifying) mechanism.PBS is a kind of common recognition machine proposed for alliance's chain
System, starting point are to improve common recognition efficiency, and control on demand goes out the block time.PoW mechanism is executed by the system node of alliance's chain in turn
Automatic digging mine is carried out, and the power of keeping accounts then is awarded to the ordinary user that step 1 is won；Certainly, common full node is also had the right (thing
First obtain system authorization) carry out PoW digging mine.
The calculating formula of PoS network weight WPoS and PoP network weight WPoP can according to need design in step 1, use formula

Solution is complicated but the easy SHA256 difficult math question of verifying, the common recognition node for solving the problem are won；So-called difficult math question is: root
According to current difficulty value, double SHA256 of each metadata of block head are made by search finding one suitable random number (Nonce)
Cryptographic Hash is less than or equal to target cryptographic Hash；
Step 4: judging which kind of common recognition node calculates successfully；If common full node calculates successfully, the node is with oneself
Address architecture Coinbase transaction generate block, directly obtain block generate right and book keeping operation power reward, system node will tie
Fruit broadcasts the whole network, and common recognition terminates；
Step 5: if system node calculates successfully, the user that wins of step 2 is broadcasted the whole network by system node, and being based on should
Station address constructs Coinbase transaction and generates block, which obtains block and generate right and book keeping operation power reward, common recognition
Terminate.
Using the main purpose of the intellectual property transaction system of block chain technology be to provide a decentralization using close
What code technology was reached common understanding can be traced anti-tamper transaction platform.Common recognition mechanism proposed by the present invention, which has merged a variety of common recognitions, to be thought
Think, it is therefore an objective to motivate the user in community to participate in community activity and transaction to the maximum extent while improving and knowing together efficiency, relate to
And main concept include user, community, node, common recognition node, intelligent contract, logical card, transaction, block.This is first introduced below
A little concepts, then introduce the particular content of common recognition mechanism proposed by the present invention.
In a kind of embodiment of intellectual property alliance chain, user refers to participating in the register account number of intellectual property transaction,
Community refers to the group being made of all users, alliance's foundation and alliance knowledge property right committee etc., and node refers to connecing
