Gold is transferred to and produces, and therefore, each assets mechanism can have the demand of book keeping operation reconciliation.
In order to realize that the demand of each assets mechanism book keeping operation reconciliation can be based on block chain skill in this specification embodiment
Art realizes the demand of each assets mechanism book keeping operation reconciliation.
In this specification embodiment, it is desirable to the demand of each assets mechanism book keeping operation reconciliation is realized based on block chain technology,
All moneys are given firstly the need of transaction in assets data broadcasting caused by the transaction in assets that will have been completed on some asset node
Node is produced, such as, it is assumed that transaction in assets data caused by the transaction in assets completed include that " transaction in assets type, assets are handed over
Easy both sides, exchange hour, transaction amount " gives transaction in assets data broadcasting to all asset nodes, that is, asset node A, assets
Node B and asset node C etc..
It should be noted that by transaction in assets caused by the transaction in assets completed on some asset node
Data broadcasting includes the asset node for generating transaction in assets data to all asset nodes.
Further, due in block chain technology only one asset node be able to record to all asset nodes broadcast
Transaction in assets data, that is to say, that only one asset node can keep accounts to the transaction in assets broadcasted, therefore,
In this specification embodiment, after giving transaction in assets data broadcasting to all asset nodes, it is thus necessary to determine which assets on earth
Node records broadcasted transaction in assets data, that is to say, that, it is thus necessary to determine which asset node is to the money broadcasted on earth
Transaction data is produced to keep accounts.
Further, illustrate in embodiment at this, determine which asset node records broadcasted transaction in assets on earth
Data can determine the asset node for recording broadcasted transaction in assets data by block chain common recognition algorithm.
It, can be with it should be noted that block chain common recognition algorithm can be and be reached common understanding algorithm using proof of work
It is that equity proves algorithm, can be delay proof of work algorithm, other common recognition algorithms, which kind of specifically used algorithm is also possible to
It can determine according to actual needs.In addition, in this specification embodiment, in order to distinguish the asset node of book keeping operation and subsequent
The asset node of book keeping operation is positioned as the first asset node herein, that is to say, that pass through by the asset node of the synchronization to be mentioned
Block chain common recognition algorithm, determines the first asset node, the first asset node records broadcasted transaction in assets data, by subsequent institute
The asset node of the synchronization to be mentioned is defined as the second asset node.
S102: the transaction in assets data are recorded.
There is the problem of transaction errors in transaction in assets both sides in order to prevent, therefore, in this specification embodiment, the first money
It produces node receiving after the transaction in assets data that all asset nodes are broadcasted, need to received transaction in assets number
According to being verified, determine whether received transaction in assets data are correct.
Again since each asset node can preserve the same block chain, and each block represented on block chain
The transaction in assets situation between each asset node is gone, it therefore, can be according to going through in block chain in this specification embodiment
History transaction in assets data determine whether received transaction in assets data are correct.
In conclusion determining whether received transaction in assets data correctly specifically may be used in this specification embodiment
To be, stored historic asset transaction data in block chain is obtained, according to the transaction in assets data that are recorded and described is gone through
History transaction in assets data verify the correctness of the transaction in assets data, when the verifying transaction in assets data are correct, record
The transaction in assets data.
It should be noted that when authenticate to transaction in assets data it is incorrect when, then do not record this assets exchange
The transaction in assets data of generation.
S103: data synchronization request is sent at least two second asset nodes.
Since mistake occurs in the book keeping operation of the first asset node in order to prevent, the first asset node is complete in record transaction in assets data
Cheng Hou, whether the transaction in assets data that other assets node needs verification the first asset node of confirmation to be recorded are correct, and due to
Each asset node requires to save an identical block chain, and therefore, in this specification embodiment, the first asset node exists
After recording transaction in assets data, data synchronization request need to be sent at least two second asset nodes.
It should be noted that data synchronization request includes recorded transaction in assets data, e.g., transaction in assets class
Type, transaction in assets both sides, exchange hour, transaction amount.
S104: the common recognition result that second asset node is returned according to the data synchronization request is received.
Since whether the transaction in assets data that other assets node needs verification the first asset node of confirmation to be recorded are correct,
Therefore, in this specification embodiment, each second asset node is synchronized in the data for receiving the transmission of the first asset node and is asked
After asking, the transaction in assets data according to entrained by data synchronization request are needed, determine that the assets that the first asset node is recorded are handed over
Whether easy data are correct, specifically, stored historic asset transaction data in block chain is obtained, according to data synchronization request institute
The transaction in assets data of carrying and the historic asset transaction data, transaction in assets number entrained by verify data synchronization request
According to correctness then return to the first asset node when the transaction in assets data entrained by the verify data synchronization request are correct
Common recognition result be reach common understanding, will common recognition result be sent to the first asset node, entrained by verify data synchronization request
When transaction in assets data are incorrect, then the common recognition result for returning to the first asset node is not reach common understanding, by common recognition result hair
Give the first asset node.
S105: according to the common recognition as a result, determining the legitimacy of record.
S106: when determination records legal, the transaction in assets data recorded are added on block chain.
Since in practical applications, there are at least two for the second asset node, that is to say, that the first asset node meeting
At least two common recognitions are received as a result, common recognition result may be identical, it is also possible to it is different, therefore, in this specification embodiment, need
It to know together based on the received as a result, the legitimacy of recorded transaction in assets data is determined, specifically, reaching described in statistics
Whether the quantity of common recognition and the quantity that do not reach common understanding, the quantity reached common understanding described in judgement are more than described do not reach altogether
The quantity of knowledge, if so, determine record it is legal, if not, it is determined that record illegal.
Further, when determination records legal, the transaction in assets data recorded is added on block chain, determination is worked as
When recording illegal, the transaction in assets data recorded will not be added on block chain, need to redefine the friendship of this assets
The legitimacy of easy data.
It should be noted that due in existing asset management field transaction in assets book keeping operation and reconciliation be independent point
The operation flow opened, will lead to so each asset node can not quick obtaining to the transaction in assets data needed so that entire money
There are certain hysteresis qualitys for the reconciliation process of production transaction, therefore, by introducing block chain technology in asset management field, so that
First asset node sends data synchronization request at least two second asset nodes to reach common understanding, to complete book keeping operation pair
Account, it is ensured that transaction in assets has identical transaction in assets data copy in different asset nodes, will need asynchronous and synchronous originally
The mode of bill is reduced to generate transaction data during transaction in assets, significantly simplifies and reduce the consumption of reconciliation link
When, the timeliness of reconciliation is effectively raised, avoiding entire transaction in assets, there are hysteresis qualitys.
In addition, reaching common understanding by all asset nodes, and assert the mode of the legitimacy of transaction in assets, assets can be prevented
There is mistake or is tampered in transaction data.
In practical applications, since transaction in assets data are to be transmitted by Internet channel, and there are numbers for third party's network
It according to the factors such as leakage, unreliable, causes transaction in assets data there may be being tampered, therefore, implements in this specification
In example, the first asset node of the transaction in assets data broadcasted to all asset nodes is received in addition to needing to verify transaction in assets number
According to correctness, it is also necessary to verify whether received transaction in assets data are tampered, specifically, the first asset node receive to
The transaction in assets data encrypted, public key and the first cryptographic Hash of all asset node broadcast, subsequently through the public key to
The transaction in assets data of encryption are decrypted, and carry out Hash operation to the transaction in assets data after decryption, obtain the second cryptographic Hash,
It according to first cryptographic Hash and second cryptographic Hash, verifies whether the transaction in assets data are tampered, then obtains block
Stored historic asset transaction data in chain, according to the transaction in assets data and the historic asset number of deals recorded
According to verifying the correctness of the transaction in assets data, when the transaction in assets data are correct and are not tampered with, record the money
It produces transaction data and does not record the transaction in assets data when the transaction in assets data are incorrect or are tampered.
It should be noted that the transaction in assets data encrypted are to complete transaction in assets and generate transaction in assets data
Asset node encrypted by private key, the first cryptographic Hash is also the money completed transaction in assets and generate transaction in assets data
Produce what node obtained generated transaction in assets data progress Hash operation, subsequent, the money which can will encrypt
It produces transaction data, public key and the first cryptographic Hash and is all broadcast to all asset nodes.
Herein it should also be noted that, according to first cryptographic Hash and second cryptographic Hash, verifies the assets and hand over
Whether easy data are tampered specifically: when first cryptographic Hash is identical as second cryptographic Hash, then the transaction in assets
Data are not tampered with, when first cryptographic Hash and second cryptographic Hash be not identical, then the transaction in assets data quilt
Illegally distort.
In addition, in step S104, the first asset node the transaction in assets data recorded can be sent to other second
Asset node relates equally to the problem of transmitting data by Internet channel, that is to say, that transaction in assets data are to pass through here
Internet channel transmission, and third party's network is there are the factors such as leaking data, unreliable, cause transaction in assets data there may be
Therefore the problems such as being tampered in this specification embodiment, receives the second asset node of transaction in assets data in addition to needing to test
Demonstrate,prove transaction in assets data correctness, it is also necessary to verify whether received transaction in assets data are tampered, specifically, the second money
It produces node and receives the data synchronization request that the first asset node is sent, wherein include: having added of being recorded in data synchronization request
Close transaction in assets data, public key and third cryptographic Hash carries out the transaction in assets data encrypted subsequently through the public key
Decryption carries out Hash operation to the transaction in assets data after decryption, the 4th cryptographic Hash is obtained, according to the third cryptographic Hash and institute
The 4th cryptographic Hash is stated, verifies whether the transaction in assets data are tampered, then obtains stored historic asset in block chain and hands over
Easy data, the transaction in assets data according to entrained by data synchronization request and the historic asset transaction data, verify data
The correctness of transaction in assets data entrained by synchronization request, the transaction in assets data entrained by the verify data synchronization request are just
When really and being not tampered with, then the common recognition result for returning to the first asset node is to reach common understanding, and common recognition result is sent to first
Asset node then returns to first when the transaction in assets data entrained by the verify data synchronization request are incorrect or are tampered
The common recognition result of asset node is not reach common understanding, and common recognition result is sent to the first asset node.
It should be noted that the transaction in assets data encrypted are that the first asset node is encrypted by private key
, third cryptographic Hash is also that the first asset node obtains generated transaction in assets data progress Hash operation, and it is subsequent, the
The transaction in assets data encrypted, public key and third cryptographic Hash can be all broadcast to all asset nodes by one asset node.
Herein it should also be noted that, according to the third cryptographic Hash and the 4th cryptographic Hash, verifies the assets and hand over
Whether easy data are tampered specifically: when the third cryptographic Hash is identical as the 4th cryptographic Hash, then the transaction in assets
Data are not tampered with, when the third cryptographic Hash and the 4th cryptographic Hash be not identical, then the transaction in assets data quilt
Illegally distort.
Although the transaction in assets data on block chain be all it is disclosed, by the transaction in assets in transmission process
Data are encrypted, and can guarantee that transaction only limits authorized user and checks, number can not be checked and be handled to unauthorized user
According to being distorted to avoid unauthorized user from maximum probability to transaction in assets data, ensure that the peace of transaction in assets data
Quan Xing.
In addition, the transaction in assets book keeping operation reconciliation based on block chain is completed jointly by being distributed in the asset node of different places
, each asset node preserves complete transaction in assets data, thus it is guaranteed that transaction in assets data between asset node
Consistency, that is to say, that all asset nodes all save the same account book, simultaneously as transaction in assets data are stored in
On multiple assets node, therefore, it is tampered or transaction in assets data in case of transaction in assets data in a small number of asset nodes
The case where being damaged will not all impact the integrality of total assets transaction data, that is to say, that avoid any one
The operation of asset node unauthorized causes entire billing and accounting system error in data, anti-tamper.
As long as the asset node for having more than more than half, which does not fail or is not tampered with, ensures that entire financial system number
According to reliable and stable, and all asset nodes share a set of accounting data copy, and it is inconsistent fundamentally to solve accounting data
The problem of.
The above are this specification embodiments to provide the method for the reconciliation based on transaction in assets, is mainly used for asset management field
It is interior, specific as follows below in conjunction with the exemplary implementation process for illustrating the reconciliation based on transaction in assets of Fig. 2:
