Based on above-mentioned device hardware structure, each implementation of the transaction monitoring and managing method the present invention is based on block chain is proposed
Example.
With reference to Fig. 2, Fig. 2 is the flow diagram of the transaction monitoring and managing method first embodiment the present invention is based on block chain.
In the present embodiment, the transaction monitoring and managing method based on block chain includes the following steps：
Step S10 when receiving the transaction request that transaction initiator is sent with preset format, calls default intelligence to close
About, and based on the default intelligent contract judge whether the corresponding transaction of the transaction request needs to introduce monitoring party；
Block chain technology have the characteristics that decentralization, information can not tamper, can be realized in many ways with block chain technology
The transaction event of participation.In the transaction of block chain, certain transaction are that monitoring party is needed to participate in and supervised to transaction；But
In process of exchange, in order to protect the privacy of transaction related side (or being participant), the identity and transaction data of dealer is usual
It can be encrypted and (be protected for example, by using the anonymity of zero-knowledge proof mode)；In this case, nontransaction related side can see
Occur to transaction, but do not know the true identity of dealer and particular transactions content；At this point, if transaction initiator does not invite
Monitoring party adds in process of exchange, and monitoring party just can not normally perform supervision function in block platform chain, so as to block chain
The order and stability of transaction platform adversely affect.Based on the above problem, proposed in the present embodiment a kind of based on block
The transaction monitoring and managing method of chain, to solve the technical issues of transaction of block platform chain supervision can not be normally carried out.
In the present embodiment, intelligent contract is previously provided in block chain transaction platform, intelligent contract is construed as code
With the set of data, in the node of deposit and block platform chain；Intelligent contract can perform automatically under the driving of time or event
Some functions such as can transmit information between each other, change the state (account information etc.) of block chain and the complete meter of figure spirit
It calculates (all things that can be accomplished with Turing machine, popular for be exactly all things that can do of general programming language).This reality
It applies in example, each transaction that block platform chain performs can call intelligent contract to perform transaction；Wherein, it is provided in intelligent contract
Relevant transaction supervision event, when the transaction that some user (can be described as transaction initiator) transmission is received in platform in block chain
During request, the intelligence contract will be called automatically, and the transaction request is parsed and identified, and determine that the transaction request will be corresponding
The type of transaction of transaction, and judge whether the transaction that transaction initiator is desired with needs introducing monitoring party to be supervised.If
The transaction does not need to introducing monitoring party and is supervised, then directly the transaction request can be broadcasted in block platform chain, make block
Each side in platform chain can receive transaction request (including the related side that merchandises)；If the transaction needs introducing, monitoring party is supervised
Pipe then enters step the processing that S20 carries out next step.
Certainly, in order to ensure block chain transaction privacy and dealer crypticity；In in the transaction request
Hold, can be pre-processed using the encrypted mode of public and private key, i.e., the transaction request is with certain format.Specifically,
In the transaction request, include transaction head, transaction content and key group；For head of merchandising, that is, include the transaction of this transaction
Type information；For transaction content, include the particular transactions details and transaction data of this transaction, this partial content may
It is related to business privacy, therefore is by encrypted for this partial content, and key group then includes that encryption is involved to encrypt
Key.For the encryption of transaction content in the present embodiment, the encryption thought that symmetric cryptography and asymmetric encryption are combined is employed,
Multi-layer security has been carried out to transaction content.Wherein symmetric cryptography refers to that the both sides for sending and receiving data use identical key
(symmetric key) to being encrypted and decrypted in plain text, encryption/decryption speed is fast, be suitble to mass data is handled, but just due to
Encryption and decryption uses same symmetric key, therefore more difficult for the management of symmetric key.And asymmetric encryption then needs two
Key：Public-key cryptography (public key) and private cipher key (private key), public key are disclosed to other sides, and private key then oneself preserves；Public key and private
Key is a pair of, if data are encrypted with public key, could only be decrypted with corresponding private key；If with private key to data into
Row encryption, then could only be decrypted with corresponding public key；Since the algorithm of asymmetric encryption is complicated so that encrypting and decrypting speed
The speed for not having symmetric cryptography decryption is fast, but since the key of encryption and decryption is different, safety is better than symmetric cryptography.This
In embodiment, it is contemplated that the data volume in transaction content is larger, and in order to ensure the speed of encryption and decryption, transaction content part will use
The method of symmetric cryptography is encrypted, and is known as symmetric key of merchandising for encrypted key；Simultaneously in order to which correlation of merchandising can make
It is decrypted with transaction symmetric key, transaction symmetric key need to be sent simultaneously when sending transaction request.It is also contemplated that transaction
Symmetric key is also possible to reveal in transmission process, therefore also needs to that transaction symmetric key is encrypted；Due to transaction pair
Claim the corresponding data volume of key smaller, considered based on safety and the double-deck of encryption efficiency, it will to the encryption for symmetric key of merchandising
It carries out, i.e., is encrypted using the public key in unsymmetrical key group by the way of asymmetric encryption, and this public key is corresponding
Private key must exist only in transaction related side, just can guarantee that other third parties can not solve the content of public key encryption in this way
It is close, so as to improve safety, be accordingly used in encryption transaction symmetric key used in encrypted public key be merchandise related side it is true
Real public key, and the true private key of the corresponding transaction related side for decryption is existed only at transaction related side, so as to ensure that
The safety of encryption data.Although due to the characteristic of block chain, transaction request can be received by all nodes in block chain,
It is the key of decrypted transaction content, the true private key of transaction related side because of the method that transaction request employs multi-layer security
Only transaction related side oneself possess, therefore even if other nodes have received anonymous handshake request, it can not also be decrypted and
Read its transaction content, effective protection business privacy.
It certainly, can also be according to particular condition in use using other Encryption Algorithm other than above-mentioned double layer encryption mode
Transaction request is encrypted.
Step S20 if the transaction needs to introduce monitoring party, parses the transaction request, judges the friendship
Whether include the monitoring party in transaction related side easily in request；
In the present embodiment, if the transaction that transaction initiator wishes to initiate needs to introduce monitoring party, which will be asked
It asks and is parsed, judged whether that monitoring party is related as one of transaction in the transaction in the transaction request
Side.If the transaction related side in the transaction request includes monitoring party, the initiator that illustrates to merchandise at this time is in initiation transaction
Meanwhile also have issued transaction to monitoring party and invite, which is introduced into this transaction, enters step S30 at this time；And
If the transaction related side in the transaction request does not include monitoring party, illustrate to merchandise initiator when initiating to merchandise, not
Transaction is sent out to monitoring party to invite, and enters step S40 at this time.
Further, when the method using the double layer encryption described in step S10 is encrypted, for transaction correlation
Whether include the judgement of monitoring party in side, can be by being obtained to the analysis of Encryption Algorithm.Specifically, since monitoring party exists
It is credible and knowable presence in block platform chain, thus the supervision public key needs of monitoring party are published in block platform chain in advance
In.And when the initiator that merchandises sends transaction request, if wishing to introduce into monitoring party, you can be added into monitoring party in transaction request
Transaction related side as one " special " (monitoring party mainly plays supervision function)；In other words, in encrypted transaction
In the transaction symmetric key of appearance, portion transaction symmetric key is encrypted with the supervision public key of monitoring party；So that prison
Pipe side can obtain transaction by the supervision private key decrypted transaction symmetric key of oneself, and with the transaction symmetric key after the decryption
Content, so as to be supervised to process of exchange.Based on above-mentioned principle, whether the transaction related side in the transaction request is judged
During including the monitoring party, as judge to whether there is by the transaction pair of the true public key encryption of monitoring party in the transaction request
Key is claimed (if there are more parts of encrypted transaction symmetric keys in transaction request, to judge wherein whether at least portion is to be supervised
The true public key encryption of Guan Fang)；If existing in transaction request by the transaction symmetric key of the true public key encryption of monitoring party, say
Transaction related side in bright transaction request includes monitoring party；If exist in transaction request by the friendship of the true public key encryption of monitoring party
Easy symmetric key then illustrates that the transaction related side in transaction request does not include monitoring party.
Step S30, it is wide in block platform chain if the transaction related side in the transaction request includes the monitoring party
The transaction request is broadcast, so that the transaction related side confirms the transaction request；
In the present embodiment, if the transaction related side in the transaction request includes monitoring party, illustrate the initiator that merchandises
While initiating to merchandise, also transaction is had issued to monitoring party and invited, monitoring party is introduced into process of exchange.According to intelligence
The related setting of contract, it is believed that this transaction request is to meet preliminary regulatory requirements, then at this time can will be in block chain
The transaction request is broadcasted in platform, so that each related side (including monitoring party) in the transaction request can get the transaction
Request, and content therein is checked and confirmed.And for applying the transaction request of double layer encryption, monitoring party is in conduct
It, can be by the supervision private key decrypted transaction symmetric key of oneself, and with the transaction pair after the decryption after related side adds in transaction
Key is claimed to obtain transaction content, correctly sees the actual conditions of transaction；Monitoring party can be examined according to monitor strategy for transaction
It looks into, it is automatic to ratify for meeting the transaction of monitor strategy；The transaction of transaction monitor strategy is not met, it is automatic to refuse；According to supervision
What strategy can not judge, then can early warning, and be pushed to related personnel, supervisor asked to carry out artificial secondary judgement.
Step S40, if the transaction related side in the transaction request does not include the monitoring party, refusing the transaction please
It asks.
In the present embodiment, if the transaction related side in the transaction request does not include monitoring party, illustrate that transaction is initiated
Side does not send out transaction to monitoring party and invites while initiating to merchandise.At this point, since transaction initiator is when initiating to merchandise,
Monitoring party is not invited to participate in transaction according to the regulation in intelligent contract, it can thus be assumed that the transaction request is insincere
's；The transaction request will not be broadcasted in block platform chain at this time, but directly refusal (rejection) transaction request.
In the present embodiment, by when receiving the transaction request that transaction initiator is sent with preset format, calling default
Intelligent contract, and judge whether the corresponding transaction of the transaction request needs to introduce monitoring party based on the default intelligent contract；
If the transaction needs to introduce monitoring party, the transaction request is parsed, judges the transaction phase in the transaction request
Whether Guan Fangzhong includes the monitoring party；If the transaction related side in the transaction request includes the monitoring party, in block
The transaction request is broadcasted in platform chain, so that the transaction related side confirms the transaction request；If the transaction
Transaction related side in request does not include the monitoring party, then refuses the transaction request.In the above manner, in the present embodiment
When the initiator that merchandises sends transaction request, judge whether the transaction needs to introduce monitoring party by intelligent contract, if the transaction
It needs to introduce monitoring party, then object is invited to be to determine whether to broadcast the transaction request to area further according to the specific of the transaction request
In block platform chain；It is achieved thereby that is conducive to by monitoring side and is merchandised in block chain for the control of transaction request in the transaction of block chain
In can normally realize that its supervises function, effectively ensure transaction order and stability in block chain transaction platform.
With reference to Fig. 3, Fig. 3 is the flow diagram of the transaction monitoring and managing method second embodiment the present invention is based on block chain.
Based on above-mentioned embodiment illustrated in fig. 2, in the present embodiment, before step S10, further include：
Step S50 receives the contract that the monitoring party is sent and creates instruction, according to creating contract establishment instruction
Default intelligence contract, wherein, the default intelligent contract includes supervision type of transaction；
Can be the section for being pre-created by monitoring party and being stored in block platform chain for intelligent contract in the present embodiment
Point in.Specifically, monitoring party can design and create corresponding intelligent contract according to practical business and the needs of laws and regulations,

Step S10 includes：
Step S11, receive transaction initiator sent with preset format transaction request when, to the transaction request into
Row parsing, obtains the corresponding type of transaction information of the transaction request；
Step S12, calls the default intelligent contract, and based on the supervision type of transaction in the default intelligent contract and
The type of transaction information judges whether the corresponding transaction of the transaction request needs to introduce monitoring party.
In the present embodiment, interdependent node in block platform chain when receiving the transaction request that transaction initiator sends,
The transaction request will be parsed, and obtain type of transaction information therein；Intelligent contract will be also called simultaneously, according to intelligent conjunction
The item (supervision type of transaction) of about middle setting and the type of transaction information got judge whether the transaction request needs to introduce
Monitoring party is supervised.
Further, in the present embodiment, for different types of transaction, corresponding monitoring party may be it is different, it is right
For different types of transaction in this intelligent contract, corresponding monitoring party can also be provided for it.When judgement transaction initiator's hair
When the transaction risen needs to introduce monitoring party, not only need to judge whether include monitoring party in the transaction related side in transaction request,
It also needs to judge whether the monitoring party is corresponding with the type of transaction of this transaction；If do not correspond to, then it is assumed that this friendship
Do not have easily to introduce monitoring party by regulation, can still refuse (rejection) transaction request at this time.
In the above manner, the intelligent contract in the present embodiment can be designed and define according to actual use demand
, monitoring party is dynamically adjusted the granularity of supervision, can both supervise every transaction or classification carries out extensive supervision,

Step S60, when receiving the transaction rejection information that the transaction related side sends, according to the transaction rejection letter
Breath refuses the transaction request.
In the present embodiment, when the transaction request of transaction initiator is broadcasted in block platform chain, in block platform chain
Transaction related side will receive transaction request.Related side merchandise after consulting content therein, if thinking, the transaction can
To receive, it can be traded with transaction initiator, then can reply relevant transaction confirmation message, block platform chain is receiving
During the transaction approval information, then relevant transaction data can be written in block chain node according to the transaction confirmation message；If
Transaction related side disagrees the transaction request, then transaction rejection information can be transmitted, and block platform chain is receiving transaction rejection
During information, then can information be vetoed according to the transaction and refuse the transaction request.
What deserves to be explained is in the present embodiment, each transaction related side of transaction is participated in (including common trading object
And regulator), for transaction request all permissions with " veto by one vote "；For example, the transaction initiated for transaction initiator A
In, transaction related side includes general transaction object B, general transaction object C and monitoring party D, wherein general transaction object B, common
Trading object C represents to confirm to the transaction, and monitoring party D thinks that the transaction violates a certain regulation, and monitoring party D can be sent out at this time
Easily rejection information is delivered, due to permission of each participant of the process of exchange with " veto by one vote ", the transaction is most
It can be rejected progress at last.In another example in the transaction initiated for transaction initiator A, transaction related side includes general transaction pair
As B, general transaction object C and monitoring party D, wherein general transaction object B, monitoring party D represent to confirm to the transaction, and common
Trading object C thinks that the transaction is unacceptable, then transaction rejection information can be transmitted in general transaction object C, so as to be asked to the transaction
Ask progress " veto by one vote ".In other words, the transaction request in the present embodiment, only when all transaction including monitoring party
When related side confirms it (agreement), relevant transaction data can be just written in each node by block platform chain, from
And it ensure that the order and stability of the transaction of block chain.
Further, when transaction request is encrypted using the double layer encryption mode described in step S10, for due to
Based on the transaction symmetric key that whether there is the true public key encryption with monitoring party in intelligent contract intelligent decision transaction request, and
Whether transaction symmetric key can not be detected can be with decrypted transaction content；So if transaction initiator has given the friendship that monitoring party provides
Easy symmetric key is wrong, and monitoring party cannot correctly read and verify transaction content, and monitoring party can be used as participant at this time
Transaction Information is directly transmitted to veto this transaction.
With reference to Fig. 5, Fig. 5 is the flow diagram of the transaction monitoring and managing method fourth embodiment the present invention is based on block chain.
Based on above-mentioned embodiment illustrated in fig. 2, in the present embodiment, after step S30, further include：
Step S70 when receiving the transaction freezing information that the monitoring party is sent, freezes according to the transaction freezing information
Tie the stateful transaction of the transaction request.
In the present embodiment, the transaction of block platform chain is supervised in order to facilitate monitoring party, can also provide transaction for it
Freezing function.When the transaction request of transaction initiator is broadcasted in block platform chain, the transaction related side in block platform chain
Transaction request will be received, which includes monitoring parties.Monitoring party can be detected transaction according to monitor strategy at this time.For
Doubtful violation but the transaction for failing lower judgement conclusion immediately, monitoring party can freeze the transaction.Specifically, monitoring party can
Transaction freezing information, the transaction that block platform chain will freeze transaction request according to the transaction freezing information are sent to block platform chain
State；At this point for each participant of transaction, may continue to be traded communication, confirmation or revocation, but the transaction exists
Final target final state can not be reached under frozen state；Block platform chain can be recorded according to the communication information of each side, still
The data of record can't be written to immediately in each node of block chain.
