Technical field
This application involves a kind of book keeping operation of block chain technical field more particularly to heterogeneous system common recognition method and system.
Background technique
Block chain can be used as a kind of computer architecture technology, it will bring huge change, example to many application scenarios Such as Industry chain management, melt conjunction, supply chain finance etc. are produced.
Common recognition mechanism is block chain technology foundation, is the important mark that block chain is different from other distributed computer technologies Will.The fundamental nature of block chain is decentralization, and the support of decentralization is common recognition mechanism.In particular, common recognition mechanism It carries two important tasks: 1) guaranteeing all fairness for participating in node；2) guarantee the one of the data of distributed heterogeneous system Cause property.
What most block chain network frameworks was all made of isomorphism node.In other words, most block chain frameworks is simultaneously Do not distinguish transaction node and accounting nodes.The structural schematic diagram of isomorphism system as shown in Figure 1 is constituted in three node In credible block chain P2P network structure, each node once completes authentication (KYC), can join the transaction of block chain, It participates in keeping accounts according to the common recognition mechanism of the chain simultaneously.
Compare the credible block chain close to true financial system, generally transaction node and accounting nodes are distinguished.Cause This, it is proposed that a kind of block chain network framework being made of heterogeneous nodes.In such framework, block chain network by two layers not Same node composition.Such as process of exchange is completed by TBC node, and clear (book keeping operation) process and completed by ABC node.This multilayer The advantages of framework is that process of exchange and clearance process can carry out in the completely different block chain network framework of mechanism, can be with Process of exchange is handled using efficient transaction common recognition mechanism, and uses relatively complete book keeping operation common recognition mechanism form processing clearance. Efficiency required for the financial transaction that this mechanism not only solves, while keeping the extension of block chain relatively easy.
However, financial transaction and book keeping operation are inter-related after all.The meaning of English word (Credit) literal translation of " credit " Think of is " buying now, pay in the future ".In the mode of doing business of " cashing on delivery " formula, credit problems are not present.Also To say, in the system of isomorphism (single node type), transaction and payment be it is simultaneous, during which there is no conversion, There is no delays.Thus, have no credit problem.And the function of node once separate, transaction there is delay, isomery clearance and The problem of payment.Clearance and payment are participated in different ways by different departments, different mechanism (different nodes) how Relationship between transaction and (clearance) book keeping operation is solved, with regard to becoming an extremely important problem.
If what transaction was taken is " exchange " mode, the clearance process traded is usually centralization, and ABC may It is a kind of framework of centralization.But in the commercial dealing of reality, more transaction are carried out in a manner of a kind of " OTC ". In other words, account book is distributed, comes out in process of exchange there is no one " authorities " and defines each participant account balance Authenticity and reliability, to determine the last payment amount of clearing, while also being undertaken by the mechanism of this centralization all Credit risk.In the process of exchange of OTC, the authenticity of account book is to be reached common understanding to determine by relationship trading side.This is also The type of transaction of block chain superiority is best embodied in reality.However, if the application of block chain is only confined in transaction Clearance above, and is traded to be placed in itself under chain and be carried out, and the authenticity of transaction is likely to become problem again.It is really landed in block chain In many supply chain finance actual scenes, many people take the method for internal " Token " to solve the problems, such as to trade between clearance, So that transaction becomes in the closed " cash transaction ", and clearing becomes internal " Token " clearance.This method is in closed platform Perhaps effectively, but in an open platform, it is difficult to close to advise and legally goes to issue what this creditable endorsement was fulfilled "Token".Therefore, studying that a kind of relationship that fiduciary mechanism solves to trade between clearance in open platform has very much must It wants.
Up to the present all block chains common recognition mechanism, is all built upon on the basis of isomorphism node.At present not yet It was found that trying to contact the Oil pipeline common recognition mechanism of transaction node and (clearance/clearing) node of keeping accounts.

Accounting nodes pond 17: the accounting nodes that all credit values are greater than epicycle election threshold value will all enter when value accounting nodes (practical accounting nodes) pond.
Dynamic credit scoring model: history, the status, the state of accounting nodes, mechanism KYC information pair participated according to transaction Accounting nodes score in real time.
Highest credit algorithm: the algorithm of active account remaining sum, effective transaction List Table is chosen from book keeping operation pond.
It is retouched below in conjunction with book keeping operation common recognition method of the specific process to heterogeneous system provided by the embodiments of the present application It states:
As shown in figure 3, be a kind of flow diagram of the book keeping operation common recognition method of heterogeneous system provided by the embodiments of the present application, This method may comprise steps of:
At least one accounting nodes that S101, the credit value for observing node selection accounting nodes are greater than setting credit threshold are made For when value accounting nodes.
In order to guarantee the efficiency of heterogeneous system and/or consider the quantity for participating in choosing node, not every accounting nodes It all can serve as when value accounting nodes.Therefore, credit threshold is preset, the credit value for choosing accounting nodes is greater than setting credit At least one accounting nodes of threshold value are as when value accounting nodes.
S102, observation node are according at least one when the credit value height of value accounting nodes, and credit value is highest works as selection It is worth accounting nodes as highest credit node.
In order to determine book keeping operation common recognition remaining sum, it is highest when value accounting nodes are as highest credit section to can choose credit value Point determines book keeping operation common recognition remaining sum by the highest credit node.Specifically, observation node is to all credit values when value accounting nodes It is ranked up, selects credit value highest when value accounting nodes are as highest credit node.
S103, when receive keep accounts request when, it is corresponding at least one update the public of itself respectively when value accounting nodes At least one updated account balance is sent to highest credit node by account book.
When receive transaction node keep accounts request when, it is corresponding one or more when value accounting nodes record book keeping operation respectively The account book of accounts payable settlement information in chain updates the public account book of itself, is respectively sent to updated account balance most High credit node.
S104, highest credit node choose common recognition remaining sum according at least one updated account balance, and will be more than common recognition Forelock gives at least one when value accounting nodes and Fei Dang value accounting nodes.
Highest credit node is counted according to a certain account balance provided when value accounting nodes and takes identical and account for more The account balance of number (" the minority is subordinate to the majority " value mode) is as common recognition remaining sum.Use " the minority is subordinate to the majority " value mode Choose some transaction party account come remaining sum (may and true remaining sum have a deviation, but be identified as the counterparty Remaining sum), using the highest credit node determine common recognition remaining sum as final account balance, ensure that the node participated in business Fairness.
The updated public account book that will know together is distributed to all nodes, including when value accounting nodes and Fei Dang value book keeping operation section Point.
According to a kind of book keeping operation common recognition method of heterogeneous system provided by the embodiments of the present application, pass through a neutral observation section Point determines that, when value accounting nodes and highest credit node, the common recognition remaining sum which is determined is as final account Family remaining sum ensure that the fairness for the node participated in business.
As shown in figure 4, be a kind of flow diagram of the book keeping operation common recognition method of heterogeneous system provided by the embodiments of the present application, This method may comprise steps of:
S201, observation node choose the quantity of node according to the efficiency and/or participation of heterogeneous system, determine setting credit threshold Value.
Before carrying out book keeping operation common recognition, observation node chooses the quantity of node according to the efficiency and/or participation of heterogeneous system (i.e. the number of vote node) determines the setting credit threshold (epicycle election threshold value) of node credit threshold controller.Note The credit value of account node is greater than the accounting nodes of the setting credit threshold into when value accounting nodes (practical accounting nodes) pond.
Start book keeping operation common recognition when, initialized respectively with lower module first: dynamic credit scoring device, pre-selection accounting nodes pond, Node credit threshold controller and when value accounting nodes pond.Wherein, the parameter of initialization includes reconciliation period, a upper billing cycle Obtained final public account book (also referred to as authoritative public account book), the public account book of accounting nodes, node credit value etc..Wherein, The reconciliation period can be time span or bill item number, such as be within every 60 minutes a reconciliation period or every 1000 public affairs Account book length is a reconciliation period altogether.
S202, observation node determine the credit value of at least one accounting nodes, determine the credit of at least one accounting nodes At least one parameter based on value includes: the true credit scoring C of mechanism1, transaction participate in score C2, book keeping operation score C3And book keeping operation When value score C4。
Observation node is checked whether according to the reconciliation cycle length in the reconciliation period and above-mentioned initialization that are previously set to be in One new reconciliation period.If it is, starting dynamic credit scoring device updates the financial status of all accounting nodes.
Specifically, the financial status of all accounting nodes is updated, that is, determines the credit value of all accounting nodes.Wherein, really At least one parameter based on the credit value of all accounting nodes includes: calmly
The true credit scoring C of mechanism1(can be obtained using big data, machine learning method)；
Transaction participates in score C2(total amount of trading in the last round of reconciliation period)；
Book keeping operation score C3；
Book keeping operation is when value score C4；
Then, the credit value of each accounting nodes is obtained are as follows: C=aC1+bC2+cC3+dC4
Wherein a, b, c, d are adjustable parameter.It can according to need and be adjusted.For example, if a > > (b, c, d), then should System is biased to by the leading clearance of the high large enterprises of commercial credit.If (b=0, c=0, d=0), then the system becomes with enterprise True credit is that mechanism is cleared in the centralization of foundation.If (a=0, c=0, d=0), then the system is with the maximum machine of trading volume Structure organization centerization clearance.
In order to avoid centralization, can balanced each parameter weight, while increasing C4Weight, guarantee last round of reconciliation The highest credit node L (T) in period will not be repeated in the period of reconciliation next time to be chosen, to guarantee the Democracy of book keeping operation.
Further, observation node also indicates " the public account of authority that all accounting nodes retain a billing cycle This ", and the public account book that all accounting nodes are held is initialized, labeled as new reconciliation period account book to be confirmed.Wherein, authoritative Public account book, refer to by it is all when value accounting nodes charge to and settlement records after reconciliation is known together.Public account book is The account book for referring to accounts payable settlement information in record book keeping operation chain, before no initializtion, it is possible to no with " the public account book of authority " Same (such as node is not engaged in billing cycle book keeping operation).New reconciliation period account book to be confirmed referred in this reconciliation week When the settlement records that value accounting nodes are recorded in phase.
At least one accounting nodes that S203, the credit value for observing node selection accounting nodes are greater than setting credit threshold are made For when value accounting nodes.
Node is observed according to the setting credit threshold of above-mentioned node credit threshold controller, the pre-selection for the condition that meets is kept accounts Node is included in practical accounting nodes pond, is defined as when value accounting nodes.
S204, observation node are according at least one when the credit value height of value accounting nodes, and credit value is highest works as selection It is worth accounting nodes as highest credit node.
When the new reconciliation period starts, the requirement of node elects highest credit node L (T) according to the observation.Book keeping operation section The highest credit node L (T-1) for working as value credit node and the credit value of oneself being distributed to upper a cycle in point pond.L(T-1) Select the highest credit node in epicycle reconciliation period according to the credit scoring of credit node, and to other nodes according to credit value into Row sequence.The highest credit node L (T-1) of upper a cycle works as value integrate-dump in oneself credit scoring simultaneously, exits When value accounting nodes pond.
S205, transaction node send the request that keeps accounts.
Correspondingly, accounting nodes receive the request that keeps accounts.
Wherein, trade authenticity verification itself is completed in TBC chain transaction.
Accounting nodes are discriminated whether first as mechanism transaction.I.e. by the relevant information of accounting nodes and transaction node data Mechanism of exchange (transaction participant) relevant information is compared in library；If the letter of the information of the accounting nodes and transaction participant Breath can match, and be exactly mechanism transaction for the accounting nodes.It trades if it is mechanism, then retains the transaction Cryptographic Hash (HashKey), the cryptographic Hash are a characteristic parameters for proving the transaction authenticity, and all premises of the present embodiment are The authenticity of transaction is completed to be proved to be in TBC (chain transaction) true.Accounting nodes are believed according to itself transaction of retention Breath wins mechanism trade detail and account balance from " the public account book of authority ", updates " privately owned account book ".Privately owned account book is remembered The record of the funds on account such as trade detail relevant to mechanism and account balance documented by account node.
S206, observation node judge whether accounting nodes are when value accounting nodes.
It is not that each book keeping operation requires whole if the too many efficiency of number of nodes can be low, therefore in order to improve book keeping operation efficiency Accounting nodes both participate in practical book keeping operation, only meet condition the talent participate in book keeping operation (when value book keeping operation).Node is observed in front Determined which be when value accounting nodes, therefore accounting nodes receive keep accounts request when, further judge the book keeping operation section Whether point is when value accounting nodes.
S207, observation node send judging result to accounting nodes.
In another realization, above-mentioned S206 step and S207 step are directly to be determined in S203 step, Directly just specify which accounting nodes had the right to keep accounts within this period when dividing when value accounting nodes, which accounting nodes Have no right to keep accounts within this period；Without implementing S206 step and S207 step.Can by directly by notice in a manner of determined Perhaps it is carried out in such a way that permission is kept accounts in setting or the method for other record accounting nodes status indicators determines.
If S208, accounting nodes are not when value accounting nodes, accounting nodes wait the request that keeps accounts next time；If note Account node be when value accounting nodes, then it is corresponding at least one ought value accounting nodes update itself public account book respectively, it is near A few updated account balance is sent to highest credit node.
If it is not mechanism transaction that accounting nodes, which judge the request that keeps accounts, and the judging result of node according to the observation, such as The fruit accounting nodes work as value node to be non-, can only just wait.If the accounting nodes are to update the book keeping operation when value accounting nodes Node public account book to be confirmed makes this keep accounts request reflection into relevant account balance.
S209, highest credit node determine the quantity for working as value accounting nodes that billing discrepancies occur less than the first setting threshold Value, the highest credit node count at least one described updated account balance, take account that is identical and occupying the majority Family remaining sum is as the common recognition remaining sum.
In this reconciliation period, kept accounts after request every time, it is all ought value accounting nodes to itself holding public account Originally it is updated, and updated related remaining sum is distributed to L (T).L (T) is issued according to accounting nodes more than remaining sum selection common recognition Volume, i.e. highest credit node choose some transaction party account come according to a certain account balance provided when value accounting nodes Remaining sum (may and true remaining sum have a deviation, but be identified as the remaining sum of the counterparty).Specifically, the common recognition that keeps accounts is adopted With " the minority is subordinate to the majority " value mode.When selection, fault-tolerant threshold value, such as 33% note below of tolerance can be set as needed Account node remaining sum calculate occur difference, i.e., generation billing discrepancies when be worth accounting nodes quantity less than the first given threshold when, It can tolerate.
Common recognition remaining sum is sent at least one when value accounting nodes and Fei Dang value book keeping operation section by S210, highest credit node Point.
L (T) the updated public account book that will know together is distributed to all nodes, including when value accounting nodes and the book keeping operation of Fei Dang value Node.
