Existing process is described in detail.
As shown in Figure 1, the medium-sized and small enterprises competitive intelligence shared platform construction method based on block chain of the embodiment of the present invention,
Include the following steps:
Step S1, platform initialization operations, comprising: the incentive mechanism and common recognition mechanism of design platform generate block chain link
The registration level one data chain of point.
(1) incentive mechanism is designed, wherein incentive mechanism uses credit score system.
Specifically, the equity in order to ensure the information owner, intelligence sharing transaction flow discloses, is transparent, it is legal be shared
The basis that platform SME-CISP is established.Reasonable incentive mechanism is only established, the common recognition mechanism of science is selected just to can guarantee block
The health operation and development of chain.In order to ensure that the legitimate rights and interests of information supplier, the present invention are made using credit score system conscientiously
For the incentive mechanism of shared platform SME-CISP, main purpose is realized to effective excitation of node and Supervised Control.
The main purpose for establishing credit score system is that convenient be managed to node controls and effectively motivate.According to section
Performance of point during intelligence sharing carries out credit scoring to it, can compete agent authority of power using credit score, exchange feelings
Resource, exchange for ready money etc. are reported, so that each node can take what one needs during intelligence sharing, and can be with base on alliance's chain
Reasonable escape mechanism is established in credit score system, so that all kinds of nodes do not have trouble and worry in platform share intelligence, is realized
The benefit of intelligence sharing.
In order to realize this target, establishes an incentive mechanism and needs to meet following basic principle:
1) initialization mechanism: participating in the federation node of intelligence sharing block chain creation, obtains the initial integration of platform distribution,
Original equity as common recognition mechanism.
2) it safeguards mechanism of exchange: in every transaction record, in addition to the points transfer of the corresponding intelligence value of completion, also disappearing
Consume additional integral for book keeping operation people's payment transaction expense.
3) rewards and punishments mechanism: for general node, rapid information is provided and obtains reward on total mark, invalid information deduction is provided
Integral；For having the federation node of book keeping operation power, it is not only applicable in the rewards and punishments mechanism of information supplier, verifying invalid information, there are also volumes
Outer reward points.
4) mechanism is passed in and out: appropriate to ensure that the apparatus of information and other information supplier's economic well-being of workers and staff weigh into escape mechanism
Benefit.In order to buy information, node can be supplemented with money and be integrated.The equity of other nodes is diluted at this time, and recharge amount is by " stock
Share out bonus by equity in east ".When node exits wish, using accumulated point exchanging cash, remaining node, which can independently be purchased, to be exited
Integrate equity.
Specifically, incentive mechanism is designed, is included the following steps:
(a) initial credit integrates:
Each node that competitive intelligence shares alliance's chain, which is added, has an initial integration C0, initial according to credit score
Change formula to be calculated.The influence factor of medium-sized and small enterprises competitive intelligence application capacity is extracted, evaluation node the most is initially believed
(Infrastructure is put into the variable of integral, including capital investment (Capital investment, CPI), infrastructure
Investment, ISI), intelligence agent put into (Intelligence employee input, IEI), wherein
C0=CPI*w1+ISI*W2+IEI*W3； (1)
Wherein, wiIndicate the weight of variable,CPI is setting investment change based on capital investment variable, ISI
Amount, IEI are that intelligence agent puts into variable；
(b) credit score changes:
In intelligence sharing and use process, setting reward cycle T0, it is believed according to the behavior of node each in the period
It is evaluated with integral, realizes the dynamic change and ranking of node credit score, integral change formula is as follows:
Ci=Ci-1+Δct+Δcrp+Δcio； (2)
Wherein, CiIndicate TiA reward all end of term, the credit score of node；ΔctIndicate TiThe transaction of period interior nodes
Integrate alteration, Δ crpIndicate that rewards and punishments integrate alteration, Δ cioIndicate disengaging integral alteration.Wherein, credit score
Change rule as shown in table 2.
Table 2
(c) credit score is exchanged and is used:
In order to have the function that credit score is managed control to node and effectively motivates, the exchange of credit score and
Using include: competition agent authority of power, exchange resource of information, exchange for ready money.Wherein, the value of credit score is divided into accumulative valence
Value and monetary value.Each reward end cycle carries out dynamic ranking according to the credit score of present node, as common recognition rank
The procuratorial reference frame in the community Duan Jingzheng.Simultaneously after each reward end cycle, the current Δ c of node can be used to exchange feelings
Report the resource of information in library.
(2) common recognition mechanism is designed
The common recognition mechanism of science may be implemented that information process of exchange is transparent, legal, make transaction record it is traceable, can look into
It askes, can appeal.The shared platform that the present invention establishes supports a variety of common recognition mechanism.
In one embodiment of the invention, the common recognition mechanism that shared platform of the invention is supported includes following a kind of or more
Kind: proof of work POW mechanism, equity prove that POS machine system, voting trust prove DPOS mechanism, Pool verifying pond mechanism, visit and account for
The fault-tolerant PBFT mechanism in front yard.
DPOS exercises book keeping operation power by node ballot proxy's node of block chain, and trustee can also obtain certain prize
It encourages, DPOS can effectively reduce the quantity for participating in verifying and accounting nodes, but must rely on token.
Relative to other mechanism of knowing together, authorization equity proves that (DPOS) there is computing resource to consume less, the common recognition time is short, gulps down
The high advantage of the amount of spitting.The present invention introduces application of the common recognition mechanism in SME-CISP by taking DPOS mechanism as an example.DPOS mechanism by by
It asks someone to create block, trustee is voted by ordinary node and generated.Wanting, which becomes trustee, needs first to register, and then publicity is promoted
The trust for seeking community carries out lobbying, before poll ranking 101 node received by system become with processing block permission by
It asks someone, and obtains reward of coining.Realizing reduces accounting nodes, quickly common recognition verifying.The work step of DPOS is as shown in Figure 5.
Improved DPOS common recognition mechanism by way of voting against, can reduce abnormal nodes as generation in the whole network node
Manage the probability of node, solve the not positive and malicious agent node of tradition DPOS mechanism ballot reject not in time caused safety compared with
The problems such as low.
The industry third party's information services and medium-sized enterprise in the top of chain of coalizing are appointed as trustee.?
Under credit rewards and punishments, excitation accounting nodes participate in competition, are in charge of by turns the resource of information that ordinary node is submitted block is recorded simultaneously
It is signed using the private key of oneself to resource of information, ensures the safety of distributed account book.
In order to supervise the behavior of trustee, guarantee the validity for being signed block, government data administrative department node due to
It endorses with powerful public credibility and enterprise, can be responsible for verifying the block that trustee creates, verify its authenticity.
Regular according to credit score simultaneously, the node in alliance's chain can increase credit score when externally providing service.
Specifically, the node in alliance's chain is serviced in external provide including the resource that provides intelligence, creation block, verifying block etc..Relatively
The illegal act of node also result in loss credit score, illegal act includes the invalid block of signature, plays tricks.Credit product
Dividing can not represent or replace.Trustee's title will be lost when the credit score of trustee is lower than integral threshold of being commissioned, it is subsequent
The medium-sized enterprise of ranking or the apparatus of information replace.When the credit score of ordinary node will be abandoned lower than 0 by alliance's chain.Pass through
Set up the participation enthusiasm that credit score system can effectively motivate all kinds of nodes, transfer medium-sized and small enterprises and the apparatus of information.
