Description.
Fig. 1 is a kind of flow chart for event prediction method that an exemplary embodiment provides.Shown in Fig. 1, this method application
In block chain node, may comprise steps of:
Step 102, determine that participant is directed to the prediction result that specified event inputs and is released to block chain, the prediction knot
Generation moment of the input time of fruit earlier than the actual result of the specified event.
In one embodiment, by creating transaction (transfer) in the client of block chain, the transaction can be passed through
The prediction result that participant inputs is distributed on block chain, a data in the distributed data base of block chain are become.
It is noted that the transaction in block chain, there are points of the transaction of narrow sense and the transaction of broad sense.The friendship of narrow sense
Easily refer to the value Transfer that user issues to block chain；For example, in traditional bit coin block chain network, transaction can be with
It is that initiate in block chain one of user transfers accounts.And the transaction of broad sense refers to that one that user issues to block chain has business
The business datum of intention；For example, operator can build alliance's chain based on actual business demand, chain portion of alliance is relied on
Affix one's name to it is some it is unrelated with value Transfer it is other types of line service (for example, event prediction, business of renting a house, vehicle scheduling business,
Settlement of insurance claim business, credit services, medical services etc.), and in this kind of alliance's chain, transaction can be user and send out in alliance's chain
The service message or service request that there is one of cloth business to be intended to.Transaction in this specification should be tended to be interpreted as
Sensu lato transaction.
In one embodiment, since block chain uses distributed data base, so that being distributed to the prediction result on block chain
It can not be tampered, it can be ensured that prediction result is true, reliable.
In one embodiment, the prediction result of participant input can be issued from above-mentioned block chain node to block chain.?
In another embodiment, the prediction result of participant input can be from being different from other block chain nodes of above-mentioned block chain node to area
The publication of block chain, and above-mentioned block chain node can know information relevant to the prediction result, can also by the prediction result (or
The cryptographic Hash of the prediction result) it is recorded in the local data base (i.e. block chain account book) of the block chain node maintenance.
In one embodiment, one or more participants can predict same event, so that can be on block chain
In the presence of the prediction result for corresponding respectively to each participant；Wherein, each participant may exist corresponding unique identification, so that
The prediction result of each participant publication can be associated with its unique identification, in order to each pre- to what is issued on block chain
Result is surveyed effectively to be distinguished.
In one embodiment, specified event is any one occurrence for being specified determination and needing to carry out prediction of result, such as a certain
The traffic condition at crossing, the rice harvest in a certain area, the typhoon formation time in a certain sea area etc., this specification not to this into
Row limitation.
In one embodiment, the input time of prediction result should earlier than the generation moment of the actual result of specified event,
The input time can be recorded in the transaction in block chain comprising the prediction result, or can be directly by the wound of the transaction
It builds constantly as the input time.In one case, when it is temporal event that this, which specifies event, i.e., this specifies event from starting
Moment is very short to the period between finish time, insufficient for participant during this period of time input prediction as a result, participate in
It side can be in any time input prediction result before the generation moment of actual result.In another case, when this is specified
When event is non-instantaneous event, i.e., participant can specify in the initial time of event to the period between finish time at this
Input prediction is as a result, participant input prediction result after the initial time for specifying event can be limited.
Step 104, the intelligent contract for being used for evaluation and foreca situation is called, the intelligence contract be used to read the prediction
As a result with the actual result, and the prediction result is compared with the actual result, with according to comparison result to chain
Outer object transmission distribution instruction, the distribution instruction are used to indicate the outer object of the chain and weigh to outside the participant the first chain of distribution
Beneficial voucher.
In one embodiment, the processing being compared to prediction result with actual result can be previously written in intelligent contract
Logic, and send the processing logic of distribution instruction based on comparative result, allows intelligent prediction knot of the contract based on reading
Fruit and actual result and automatically determine whether need send distribution instruction；Wherein, since the processing logic on intelligent contract is public affairs
Content is opened, and entire treatment process is automatically performed by intelligent contract, there is no manual interventions, so that either to prediction result
With the transmission relatively or to distribution instruction of actual result, can ensure objective, just.
In one embodiment, when prediction result and actual result match, show the participant that the prediction result is provided
There is certain accuracy for the prediction of result of above-mentioned specified event.So, by outside chain object send distribution instruction, make
It obtains the outer object of the chain and distributes equity voucher outside the first chain to participant, can control each participant for equity voucher outside chain
The volume of holding, to realize label effect for each participant to a certain extent: holding the more participation of the outer equity voucher of chain
Side is stronger for the predictive ability of event result, thus during subsequent event prediction, it can quickly filter out accordingly pre-
The strong participant of survey ability, with obtain from these participants may relatively more accurate prediction result.
In one embodiment, the outer equity voucher of chain is for characterizing certain equity, to realize on participant Accurate Prediction
The excitation for stating specified event facilitates the participant and continues to participate in prediction to successor, to realize benign cycle.Such as
When implementing predetermined registration operation on block chain, for example the predetermined registration operation may include publication transaction, initiates common recognition (such as base participant
Initiated in the practical Byzantine failure tolerance algorithm of PBFT) etc., equity voucher outside chain can be converted into intelligence of equal value in block chain
Assets voucher and by distributing a certain amount of intellectual capital voucher to each block chain node, to promote the predetermined registration operation can
It smoothly completes as early as possible.
In one embodiment, the outer equity voucher of chain may include the voucher for characterizing equity outside any type of chain, example
Member's integral, the discount coupon on transaction platform, convertible note, minimum price certificate such as in member system, this specification be not right
This is limited.
In one embodiment, above-mentioned intelligent contract can be called under transaction or the driving of another intelligent contract, with
It triggers it and reads above-mentioned prediction result and actual result etc. from block chain, so that the event for further implementing this specification is pre-
Survey scheme.In one case, specify the actual result of event can be by prophesy machine (Oracle) node in the block chain
It is distributed on the block chain, since the data that prophesy machine node provides are considered absolutely reliable, thus may insure the reality
As a result accuracy.In another case, the actual result for specifying event can be after knowing together by the block chain
Either block chain node is distributed on the block chain, for example the either block chain node can be initiated in block chain common recognition,
Confirmed with the actual result provided for the either block chain node, when the actual result has passed through each block chain node
Common recognition after, show the actual result have enough accuracy, can be applied to be compared with prediction result.
In one embodiment, the specified event includes one or more subevents, and the prediction result is used for described
One or more subevents carry out prediction of result；Wherein, the intelligent contract is used in the prediction result to one
Or in the correct situation of the prediction of result of multiple subevents, the distribution instruction is sent to the chain outer platform, so that outside chain
Object distributes equity voucher outside the first chain to the participant.In other words, when prediction result is to the prediction of result of specified event
When completely correct, which is judged to being matched with the actual result of the specified event by intelligent contract.
In one embodiment, the specified event includes multiple subevents；The corresponding power of the outer equity voucher of first chain
Beneficial size is positively correlated with the accounting by the subevent of the prediction result Accurate Prediction in the multiple subevent.For example, working as
When prediction result is identical with actual result, i.e., by the subevent of the prediction result Accurate Prediction in the multiple subevent
In accounting be 100%, the equity size that the outer equity voucher of the first chain is characterized can be preset maximum value；Work as prediction result
When completely not identical as actual result, i.e., by subevent the accounting in the multiple subevent of the prediction result Accurate Prediction
Than being 0%, the equity size that the outer equity voucher of the first chain is characterized can be preset minimum value (0 or other preset values).
In one embodiment, the equity size that the outer equity voucher of the first chain is characterized can be using linear change, such as accounts for
When than being 30%, equity size is the 30% of preset maximum value, in another example equity size is preset maximum value when accounting is 80%
80% etc..In another embodiment, the equity size that the outer equity voucher of the first chain is characterized can be using nonlinear change, example
When such as accounting being 30%, equity size is the 10% of preset maximum value, then when for example accounting is 80%, equity size be it is default most
50% be worth greatly, in another example equity size is 80% etc. of preset maximum value when accounting is 95%.
In one embodiment, the specified event includes multiple subevents, when prediction result and actual result and non-fully
When consistent, and though by accounting of the subevent of the prediction result Accurate Prediction in the multiple subevent why, can be with
It is determined as that the two mismatches, so that intelligent contract is not necessarily to the object transmission to outside chain and distributes instruction, to will not distribute to participant
The outer equity voucher of first chain.
In one embodiment, can determine that the outer equity voucher of the second chain that the participant is held is frozen, using as with
In the guarantee voucher for the validity for assuring the prediction result；Wherein, the intelligent contract be used for the prediction result not
It is sent in the case where assigned in the actual result to the manager of the guarantee voucher and deducts instruction, to release the participant pair
The guarantee voucher holds relationship.Freezed by equity voucher outside the second chain for holding participant to assure voucher, so that
The guarantee voucher be used for participant provide prediction result assure, certain participation door participant can be arranged
Sill avoid arbitrarily participating in and influencing the Accurate Prediction to above-mentioned specified event.
In one embodiment, when the equity for assuring voucher characterization is bigger, show participant to the prediction knot itself provided
Fruit is more self-confident, then it is extremely strong to show that participant has really to a certain extent when prediction result and actual result match
Predictive ability, thus the equity size by being characterized equity voucher outside the first chain be set as and the guarantee voucher characterize
Equity size be positively correlated, can the predictive ability to corresponding participant more precisely marked, and to corresponding
Participant is greatly motivated.
In one embodiment, it even if participant does not freeze to form guarantee voucher, may still participate in specified event
Prediction of result, and equity voucher outside the first above-mentioned chain is obtained in the case where prediction result and actual result match.Another
In one embodiment, when participant does not freeze to form guarantee voucher, the prediction result of participant input is judged as in vain, making
It can not really participate in the prediction of result to specified event；Alternatively, in the case where prediction result and actual result match,
Although can distribute equity voucher outside the first chain to the participant, the outer equity voucher of first chain is unable to characterize any equity
It is equivalent to the outer equity voucher of unallocated any chain, so that the participation of the participant is meaningless.
In one embodiment, the Call Condition of the intelligent contract may include: the third chain that the outer object of the chain is held
Outer equity voucher is frozen, and the outer equity voucher of the third chain freezed enough responds distribution instruction.Pass through
Before calling intelligent contract, equity voucher freezes outside the third chain held to object outside chain, can lock this portion in advance
The outer equity voucher of point chain, even if so that the outer object of chain refuse to distribute to participant after receiving distribution instruction outside the first chain equity with
The outer equity voucher of chain demonstrate,proved or held is not enough to complete to distribute, can also be smooth based on equity voucher outside the third chain freezed
Implement batch operation.
In one embodiment, if the outer object of chain distributes equity voucher outside the first chain to participant according to distribution instruction,
Then the outer object of chain can restore to hold equity voucher outside third chain.If the outer object of the chain will not be weighed outside first chain
Beneficial voucher is distributed to the participant, for equity voucher outside distribution chain intelligent contract can to outside the third chain equity with
The manager of card, which sends, forces distribution instruction, with from obtaining outside first chain in equity voucher outside the frozen third chain
Equity voucher is simultaneously distributed to the participant.Wherein it is possible to the response by object outside block chain monitoring nodes chain to distribution instruction
Situation, such as the response condition can be passed to block chain by above-mentioned prophesy machine node, so that it is guaranteed that the accuracy of its message；Or
Person, after above-mentioned response condition is passed to block chain by prophesy machine node, the intelligent contract for equity voucher outside distribution chain can be with
Automatically determine whether the outer object of the chain distributes equity voucher outside first chain to the participant, and in automatic transmission
The pressure distribution instruction stated.
Fig. 2 is a kind of schematic diagram for predicted events result that an exemplary embodiment provides.As shown in Figure 2, it is assumed that user A
Wish that the prediction of result for participating in being directed to event B, the user A can be by being equipped with the 21 input prediction result of mobile phone of client.
The prediction result can be obtained by user A by any way, for example, by user A by unshowned server in Fig. 2 to going through
History data carry out big data analysis and obtain, and are for another example obtained by user A according to experience, and this specification is not to this progress
Limitation.
Equipment 22 is configured as a block chain node in block chain, which can receive the pre- of the transmission of mobile phone 21
Survey result；The login account in client run based on mobile phone 21, the prediction result can be determined that from user A.
Certainly, above-mentioned prediction result can also be sent to other block chain nodes in block chain, these block chain links by mobile phone 21
The treatment process of point is similar with equipment 22, can be with reference to the associated description in this specification for equipment 22.And other users
Can to event B carry out prediction of result, and the mobile phone used by itself or other electronic equipments be sent to equipment 22 or other
At block chain node, the treatment process of these users is similar with user A, can be with reference to the correlation in this specification for user A
Description.
Equipment 22 can know together to the prediction result of user A input in block chain, so that the prediction result is logical
It is released to block chain after crossing common recognition, to record into the distributed data base of block chain, i.e., " cochain ".This specification is simultaneously unlimited
Surely the type of the common recognition algorithm used；For example, the equipment 22 can when the block chain locating for the equipment 22 is alliance's chain or publicly-owned chain
With based on such as PBFT (Practical Byzantine Fault Tolerance, practical Byzantine failure tolerance) algorithm to other
Block chain node initiates common recognition, and the prediction result is distributed to block chain after through common recognition, is recorded it to block chain
Distributed data base in；For another example the equipment 22 can be with other blocks when the block chain locating for the equipment 22 is publicly-owned chain
Chain node is based on POW (Proof of Work, proof of work) algorithm, POS (Proof of Stake, equity prove) algorithm
Or other algorithms competition book keeping operation power, and the block chain node from obtaining book keeping operation power charges to transaction data into respective block, and work as
When the transaction of prediction result comprising user A input is credited to, which can be recorded to the distributed number of block chain
According in library.
It may include prophesy machine node 23 in block chain, the available chain of prophesy machine node 23 is outer (i.e. except block chain)
Data, and data outside chain are passed in block chain.For example, the prophesy machine node 23 can obtain the practical knot of event B outside chain
Fruit, and the actual result is distributed in block chain, to be recorded in the distributed data base of block chain, i.e., " cochain ".
In order to determine whether the prediction result of user A input matches with actual result, especially for avoiding handling
It is related to human intervention in the process, ensures accuracy and validity, intelligent contract, the intelligence can be created on block chain in advance
Definition has a function logic for determining the match condition between prediction result and actual result in contract, which can be with
Automatically the actual result of the event B incoming with prophesy machine node 23 of the prediction result to user A input is compared, so that comparing
As a result objective, accurate.
In one embodiment, intelligent contract can by block chain transaction or other intelligent contracts be called, with touching
Its automatic implementation correlation function logic is sent out, it is for example above-mentioned for determining the function of the match condition between prediction result and actual result
Energy logic etc..Other intelligent contracts can be traded or be called to equipment 22 by issuing in block chain, to realize to above-mentioned intelligence
The calling of contract；Alternatively, can be called by other block chain nodes to above-mentioned intelligent contract, this specification not to this into
Row limitation.After called, above-mentioned intelligent contract can be run in equipment 22, with the above-mentioned function logic of automatic implementation.
In order to make it easy to understand, being implemented below with reference to Fig. 3 and Fig. 4 for the intelligent contract referred in embodiment illustrated in fig. 2
Function logic be described in detail.
Fig. 3 is the flow chart for the function logic that a kind of intelligent contract that an exemplary embodiment provides is implemented.Such as Fig. 3 institute
Show, which may comprise steps of:
Step 302, the prediction result of user A is obtained from block chain.
In one embodiment, the prediction result of user A is recorded in a certain transaction on block chain, which can be by
Labeled as related to event B, intelligent contract is allowed to find the transaction from block chain accordingly, and obtain the pre- of user A
Survey result.For example, intelligent contract can be by scanning the transaction record of particular address or the transaction record of specific serial number, i.e.,
It can get the prediction result of user A input.
In one embodiment, the prediction result for there are other users to input also is recorded on block chain, intelligent contract can pass through
Similar fashion obtains these prediction results, no longer repeats one by one herein.
Step 304, actual result is obtained from block chain.
In one embodiment, the incoming actual result of prophesy machine node 23 is recorded in a certain transaction on block chain,
The transaction can be marked as related to event B, allow intelligent contract to find the transaction from block chain accordingly, and obtain
Take the actual result.For example, intelligent contract can pass through the transaction of the transaction record or specific serial number of scanning particular address
Record, can be obtained the actual result.
Step 306, compare the prediction result of user A and the actual result of event B, determine the prediction result and actual result
It is whether consistent.
In one embodiment, it is assumed that event B is unique cases, does not include multiple subevents, so that prediction result and reality
As a result there is only two kinds of situations: result is consistent or result is inconsistent.Prediction result and actual result should data having the same
Structure compares operation in order to realize.For example it is assumed that event B is traffic condition of a certain crossing in peak period on and off duty, prediction
As a result, actual result can separately include a field m, and congestion is indicated as field m=0, is indicated not as field m=1
Congestion.
Step 308A determines user A with the presence or absence of guarantee voucher when prediction result is consistent with actual result.
Step 310A sends distribution instruction 1 to mechanism C when there is guarantee voucher.
Step 310B sends distribution instruction 2 to mechanism C when there is no guarantee voucher.
In one embodiment, user A can configure corresponding guarantee voucher to entered by himself prediction result, with for pair
The validity of the prediction result is assured.For example, user A may exist corresponding account a except block chain, and by being somebody's turn to do
Account a holds the outer equity voucher of certain chain, can be by freezing to equity voucher outside at least part chain in account a
Knot, using as above-mentioned guarantee voucher；For example, equity voucher outside at least part chain can be temporarily transferred to by account a
In dedicated voucher Frozen Account, or equity voucher addition outside at least part chain can be freezed to mark in account a
Know etc., this specification is limited not to this.In this embodiment, the guarantee voucher is not necessarily: if there is guarantee with
Card can send distribution instruction 1 to mechanism C, so that mechanism C equity voucher S1 to outside user's A distribution chain, if there is no load
Voucher is protected, distribution instruction 2 can be sent to mechanism C, so that mechanism C equity voucher S2 to outside user's A distribution chain；Wherein, chain
The equity that outer equity voucher S1 is characterized should be greater than the equity that the outer equity voucher S2 of chain is characterized, to show to provide user A
The excitation of voucher is assured, and the outer equity voucher of the chain that user A is held is more, to show that the predictive ability of the user A becomes
Strong or prediction accuracy increases.Wherein, the equity that chain outer equity voucher S1, S2 is characterized can be outside fixed value or the chain
The equity that the equity that equity voucher S1, S2 are characterized can be characterized with guarantee voucher is positively correlated, i.e. guarantee voucher is characterized
Equity it is bigger/more when, the equity that the chain outer equity voucher S1, S2 are characterized is bigger therewith/more.
In one embodiment, in order to avoid user A arbitrarily issues the prediction result to event B, ensures that the prediction result has
Meaning can be arranged a set threshold for the prediction of result of participating user B, for example require user A that must tender guarantee voucher.Cause
This, in the case where existing and assuring voucher, can to outside user's A distribution chain equity voucher S1, equity voucher S1 is used outside the chain
In the certain equity of characterization；And when there is no in the case where guarantee voucher, equity voucher S2 is unable to characterize to outside the chain of user A distribution
Any equity is equivalent to the outer equity voucher of unallocated any chain, then the participation of user A will be meaningless.
Step 308B determines user A with the presence or absence of guarantee voucher when prediction result and actual result are inconsistent.
Step 310C, when existing, when assuring voucher, deduction assures voucher.
In one embodiment, when prediction result and actual result are inconsistent, i.e. user A to the prediction of result of event B not
Accurate or prediction of failure can make user A termination hold equity outside the corresponding chain of guarantee voucher by deducting guarantee voucher
Voucher, then the outer equity voucher of the chain held of user A is reduced, to show that the predictive ability of the user A dies down or prediction accuracy
It reduces.
In one embodiment, the corresponding guarantee voucher of user A can have a manager, such as account management system etc.,
Intelligent contract can deduct instruction by sending to the manager, so that the manager instructs in response to the deduction and deducts corresponding
Guarantee voucher.
Fig. 4 is the flow chart for the function logic that the intelligent contract of another kind that an exemplary embodiment provides is implemented.Such as Fig. 4 institute
Show, which may comprise steps of:
Step 402, the prediction result of user A is obtained from block chain.
Step 404, actual result is obtained from block chain.
In one embodiment, step 402-404 can refer to step 302-304 shown in Fig. 3, and details are not described herein again.
Step 406, compare the prediction result of user A and the actual result of event B, determine the prediction result and actual result
It is whether completely the same.
In one embodiment, it is assumed that event B includes multiple subevents, if the prediction result of user A is to all sub- things
The equal Accurate Prediction of part, then the prediction result and actual result are completely the same；And the if only Accurate Prediction part subevent user A
As a result, user A inherently implement prediction only for part subevent, then prediction result and actual result possibility portion
Divide consistent；It is of course possible to user A is incorrect to the prediction of all subevents, then prediction result and actual result be not completely
Unanimously.
In one embodiment, prediction result and actual result should data structure having the same, compare in order to realize
Operation.For example it is assumed that event B is a certain crossing in the traffic condition of peak period on and off duty, prediction result, actual result can divide
Not Bao Han traffic condition during field m1 and field m2, m1 field references morning peak, m2 represent evening peak during traffic shape
Condition indicates congestion, the not congestion during expression morning peak as field m1=1 during morning peak as field m1=0, when this
Congestion, the not congestion during expression evening peak as field m2=1 during expression evening peak when field m2=0.
Step 408A determines user A with the presence or absence of guarantee voucher when prediction result and actual result are completely the same.
Step 410A sends distribution instruction 1 to mechanism C when there is guarantee voucher.
Step 410B sends distribution instruction 2 to mechanism C when there is no guarantee voucher.
In one embodiment, step 408A, step 410A and step 410B can with reference to step 308A as shown in Figure 3,
Step 310A and step 310B, details are not described herein again.
Step 408B determines that prediction result is with actual result when prediction result and actual result are not completely the same
No part is consistent.
Step 410C, when prediction result and actual result it is completely inconsistent when, assure voucher if it exists, then deduct guarantee with
Card.
In one embodiment, analogously with embodiment illustrated in fig. 3, user A can match entered by himself prediction result
Corresponding guarantee voucher is set, to assure for the validity to the prediction result.So, when prediction result and actual result
When completely inconsistent, i.e. user A can make the prediction of result inaccuracy or prediction of failure of event B by deducting guarantee voucher
It obtains user A termination and holds the outer equity voucher of the corresponding chain of guarantee voucher, then the outer equity voucher of chain that user A holds is reduced,
To show that the predictive ability of the user A dies down or prediction accuracy reduces.
Step 410D determines user A with the presence or absence of guarantee voucher when prediction result is consistent with actual result part.
Step 412A sends distribution instruction 3 to mechanism C when there is guarantee voucher.
Step 412B sends distribution instruction 4 to mechanism C when there is no guarantee voucher.
In one embodiment, similar with step 410A-410B, when prediction result is consistent with actual result part,
Show that user A has a degree of predictive ability, thus for the mark to this fractional prediction ability, and for user A
Excitation, can to mechanism C send distribution instruction 3 or distribution instruction 4 so that mechanism C distributes equity outside certain chain to user A
Voucher.In this embodiment, the guarantee voucher is not necessarily: if there is guarantee voucher, can to outside user's A distribution chain equity
Voucher S3, if there is no guarantee voucher, can to outside user's A distribution chain equity voucher S4；Wherein, big in the equity characterized
Small aspect: S1 > S3 > S4, S1 > S2 > S4.
In one embodiment, the equity that chain outer equity voucher S1, S3 is characterized can be corresponding fixed value, or
The equity that the equity that the chain outer equity voucher S1, S3 are characterized can be characterized with guarantee voucher respectively is positively correlated, that is, assures
When the equity that voucher is characterized is bigger/more, the equity that the intellectual capital voucher S1, S3 are characterized is bigger therewith/more.
In one embodiment, in order to avoid user A arbitrarily issues the prediction result to event B, ensures that the prediction result has
Meaning can be arranged a set threshold for the prediction of result of participating user B, for example require user A that must tender guarantee voucher.Cause
This, in the case where existing and assuring voucher, can to outside user's A distribution chain equity voucher S3, equity voucher S3 is used outside the chain
In the certain equity of characterization；And when there is no in the case where guarantee voucher, equity voucher S4 is unable to characterize to outside the chain of user A distribution
Any equity is equivalent to the outer equity voucher of unallocated any chain, then the participation of user A will be meaningless.
In one embodiment, since user A is only in the case where prediction result and actual result match, can divide
Be fitted on the outer equity voucher of corresponding chain, thus the outer equity voucher of chain held of user A can be used for characterizing its predictive ability or
Prediction accuracy, i.e., when outside the chain held equity voucher it is more or characterization equity it is bigger when, show the predictive ability of the user A
Stronger or prediction accuracy is higher.
Wherein, equity voucher outside chain can also be used for other aspects by user A.For example, the Partial Block chain in block chain
Node can play the part of the role of anchor point, and equity voucher outside chain that user A holds can be converted to intellectual capital voucher of equal value,
The for example house property voucher, security voucher, stock certificates, deposit certificate etc. of anchor point publication, this specification is limited not to this
System.When equity voucher is used to characterize the predictive ability of user outside chain, only allow equity voucher outside chain converting to intellectual capital
Voucher, and limit and intellectual capital voucher is converted into equity voucher outside chain；Certainly, if existed simultaneously for characterizing the pre- of user
The outer equity voucher of the second class chain of the outer equity voucher of the first kind chain of survey ability, the predictive ability for being not used in characterization user, can be with
Intellectual capital voucher is converted to equity voucher outside first kind chain and allows equity voucher outside chain converting to the second class chain by limitation
Outer equity voucher.
In embodiment as shown in Figure 3-4, when mechanism C receive distribution instruction 1~4 when, may for various reasons and
Equity voucher S1~S4 outside chain is not distributed to user A, the outer equity voucher of the chain that for example mechanism C holds is not enough to respond distribution and refers to
Enable 1~4 (i.e. the outer equity voucher of the chain that mechanism C holds is less than/is less than the outer equity voucher S1~S4 of chain) or other reasons.In order to
Avoid the generation of above situation, it is ensured that user A can smoothly obtain the outer equity voucher S1~S4 of chain, initiate for event B's
Before prediction, it can determine that mechanism C freezes equity voucher outside at least part chain held first, can for example freeze in finger
At fixed manager's (such as certain third party's financial platform), and block can be passed to for result is freezed accordingly by foretelling machine node 23
Chain, then above-mentioned intelligent contract can execute processing logic as shown in Figure 3 or Figure 4 after scanning freezes result to this, it is no
It can not then execute.And distribution instruction 1~4 be sent to mechanism C after, prophesy machine node 23 can by mechanism C to chain outside
The distribution condition of equity voucher S1~S4 is passed to block chain, and equipment 22 can call the intelligence distributed for equity voucher outside chain
Contract, which can force distribution instruction by sending to above-mentioned manager, so that the chain that the manager will freeze
Outer equity voucher thaws, and distributes equity voucher outside corresponding chain to user A, which is not constrained by mechanism C.
