It is the remaining sum according to both parties in Transaction Information and corresponding revenue and expenditure, is locally carrying out reconciliation, obtains reconciliation as a result, such as account book
It is consistent or inconsistent.Understand the method for the present invention to further facilitate, the book keeping operation section for the Transaction Information that client is sent will be received
Point is labeled as node a, and other accounting nodes are labeled as node b, c, d ..., and so on.
Step S20 broadcasts Transaction Information to block chain network, for block when reconciliation result is that account book is consistent
Other accounting nodes in chain network initiate common recognition；
In the present embodiment, mechanism of knowing together (NNAC, network notify agree consensus), is by special section
The ballot of point, the verification and confirmation of complete swap in a short period of time, i.e., to a transaction, if if interests are incoherent
A dry accounting nodes can reach common understanding, so that it may to think that the whole network can also reach common understanding to this.It is preferred that all accounting nodes are super
Cross 50% or more node reach an agreement after, could complete swap account approval and book keeping operation.
In the present embodiment, only when node a completes local reconciliation and reconciliation result a is that account book is consistent, by Transaction Information
Broadcast is to block chain network, even if online other accounting nodes receive the Transaction Information that node a is sent, then other book keeping operations
Node respectively carries out local reconciliation, then the result of respective reconciliation is broadcasted, and realizes common recognition.It is exactly briefly Qi Tajie
Point b, c, d receive the Transaction Information of node a broadcast, and node b local reconciliations obtain reconciliation result b, and broadcast to block link network
Network so that node a, c, d are received, same node c local reconciliations, obtain reconciliation result c, and are broadcasted to block chain network so that
Node a, b, d are received, and so on.It should be understood that in practical application, the quantity of other accounting nodes of common recognition is participated in very
To more, such as 1000, it is adjusted with specific reference to actual conditions.
Step S30 receives the reconciliation of other accounting nodes feedbacks as a result, simultaneously according to common recognition condition is preset, obtains book keeping operation knot
Fruit；
Accounting results are issued to client by step S40, wherein accounting results are included at least to keep accounts successfully or keep accounts and be lost
It loses.
In the present embodiment, default common recognition condition is a set of rule to judge whether common recognition reaches an agreement pre-set
Then, be pre-set it is a set of distinguishing the mode of different accounting results.By broadcasting Transaction Information, ginseng is then received again

Based on above-described embodiment, in the present embodiment, above-mentioned steps S10, when receiving the Transaction Information of client transmission,
Local reconciliation operation is executed, obtains reconciliation as a result, including：
Step S11 determines that the client is transaction originating end and determination when receiving the Transaction Information of client transmission
The transaction id of transaction originating end；
Step S12 searches public key corresponding with the transaction transaction id of originating end, for right in local block data library
The private key of Transaction Information is verified；
Step S13 understands the transaction content of Transaction Information when public key is consistent with private key, obtains the friendship at transaction acceptance end
Easy ID and transaction amount；
Step S14, the transaction id of transaction id and transaction acceptance end based on transaction originating end, obtains local block data library
The account balance of middle record；
Step S15 is based on account balance and transaction amount, judges whether the revenue and expenditure of both parties is equal；
Step S16, if revenue and expenditure is equal, reconciliation result is that account book is consistent；
Step S17, if revenue and expenditure is unequal, reconciliation result is that account book is inconsistent.
In the present embodiment, accounting nodes a receives the Transaction Information of client transmission, you can determines the user of the client
For transaction less, merchandise initiator, thus determines that the client is transaction originating end.It should be understood that each transaction
Less and beneficiary (corresponding transaction originating end and transaction acceptance end) are there will necessarily be, both sides are each with having one's own account by oneself
Location, i.e. transaction id.Be stored in the local block data library of accounting nodes multiple accounts and with the relevant transaction record of account,
The data such as public key.Since Transaction Information is encryption data, thus according to the transaction id of transaction originating end, in local block data library
In find corresponding public key, to decrypted transaction information.Such as after receiving the Transaction Information of Zhang San's transmission, uses open first
Three public key verifications trading signature, is verified, then reduction obtains transaction amount 100 from encryption word string with public key, then root
According to the amount of money summation in both parties' account, judge whether revenue and expenditure is equal, if revenue and expenditure is equal, proves that transaction is effective, can hold
Row common recognition operation in next step.For example Zhang San (less) account has 900 originally, after paying 100, account balance is 800 at present, Lee
Four (beneficiary) accounts have 500 originally, and after taking in 100, account balance is that 600, the i.e. expenditure of both sides and income are equal at present, this
Secondary transaction is effective.If revenue and expenditure is unequal, directly returns and fail to Zhang San, closing the transaction.
Based on above-described embodiment, in the present embodiment, above-mentioned steps S30, receive the reconciliation of other accounting nodes feedbacks as a result,
And according to default common recognition condition, accounting results are obtained, including：
Step S31 receives the reconciliation of other accounting nodes feedback as a result, simultaneously cumulative calculation quantity；
Step S32 obtains the sum in block chain network in online accounting nodes and current adjustment value, to count
Calculate receiving node number；
Whether step S33, the quantity for monitoring the cumulative calculation in preset time are greater than or equal to receiving node number；
Step S34, if the quantity of cumulative calculation is greater than or equal to receiving node number in preset time, based on reception
The participation of other each accounting nodes calculates consensus value；
Step S35, judges whether consensus value is greater than or equal to receiving node number；
Step S36, if consensus value is greater than or equal to receiving node number, it is determined that common recognition is reached an agreement, and determines book keeping operation knot
Fruit is to keep accounts successfully；
Step S37, if consensus value is less than receiving node number, it is determined that common recognition is inconsistent, and determines that accounting results are book keeping operation
Failure；
Step S38, if the quantity of cumulative calculation is less than receiving node number in preset time, it is determined that network waits for super
When, and determine that accounting results are that book keeping operation fails.
In the present embodiment, due to broadcasting Transaction Information to block chain network, and then the other notes online to current network
Account node initiates common recognition, to which other accounting nodes respectively complete local reconciliation after receiving Transaction Information, and by reconciliation knot
Fruit is broadcasted, to which accounting nodes a can receive the reconciliation result of other accounting nodes feedbacks.Simultaneously because the whole network is online
Accounting nodes quantity and to eventually receive the quantity of the corresponding accounting nodes of feedback be variable, thus cumulative calculation
The quantity of the reconciliation result of reception is to get to the quantity of the accounting nodes of feedback.
Wherein, the formula of calculating receiving node number is
NAlwaysTo be in the sum of online accounting nodes in block chain network, existing network Heartbeat mechanism can be passed through herein
All online accounting nodes, and statistical magnitude are monitored in real time；
T is current adjustment value, and T can be set according to actual business requirement herein, and
Calculate consensus value formula be
P is accounting nodes participation：(m is the whole network transaction count of this accounting nodes a records, and q saves for this book keeping operation
The accounting nodes b, c ... of point record wait the correct number of common recognition for once participating in book keeping operation.P initial values are 1,0 P≤1 <)
It should be noted that
Assuming that being in the total N of online accounting nodes in current block chain networkAlwaysIt is 1000, current adjustment value T is 1,
So receiving node number can be calculated 501.The accounting results of 501 accounting nodes feedback are not received in preset time, then
It determines that network waits for time-out, while determining that accounting results are that book keeping operation fails.If receiving 501 accounting nodes in preset time
When the accounting results of feedback, you can execute the consensus value that common recognition is calculated, and calculated and be greater than or equal to 501, then explanation is all at present
Accounting nodes are more than that 50% or more node is reached an agreement, and can complete approval and book keeping operation to this transaction account, at this time
Determine that accounting results are to keep accounts successfully.Illustrate that common recognition is not reached an agreement if the consensus value calculated is less than 501, determines book keeping operation at this time
As a result it is book keeping operation failure.Ensure the high reliability of data by common recognition, while operation is at low cost, can reduce resource consumption, improves
Efficiency.
It is further alternative, in one embodiment of bill processing method the present invention is based on block chain database, for update
And synchronous block data, the bill processing method based on block chain database of the present embodiment further include：
When common recognition is reached an agreement, based on Transaction Information and this accounting nodes known together is participated in, updates local block
Transaction data in database.
In the present embodiment, when common recognition is reached an agreement, illustrate that this transaction is effective, by consistent Transaction Information of knowing together, such as
Revenue and expenditure detail updates the personal account book of both parties.It will participate in the accounting nodes of this common recognition, a certain accounting nodes such as participated in
