The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Description based on background technology, it can be appreciated that in the prior art, since the situation of current transaction reality is, transaction
Recipient be generally hotel owner, such block participates in the condition that node has real-time online, but the initiation of block chain transaction
Side, generally ordinary populace user can generally use mobile terminal, not have the condition for being linked into block chain in real time usually.
And on the one hand, when current block chain is traded verification, for example, as shown in Fig. 2, when node A and node B transaction,
Both sides, which participate in node, must all keep being in block chain network on-line mode, and the various broadcast recodings of real-time reception are initiated by transaction
Fang Jiedian generates transaction record and is broadcast in block chain P2P networks after signing, but when the mobile terminal participated in business can not
Ensure to be in block chain network on-line mode in real time, thus, cause block chain to be difficult to apply in current transaction.
On the other hand, the operating mechanism based on block chain, block chain must be written into block ability until transaction record
Confirm the transaction, i.e., is needed after receiving the verification information that block is written into continued reference to Fig. 2, node B, just can confirm that transaction
Success, however, current transaction especially needs fast, to need to complete payment in 1~2 minute and its confirm, wait for face-to-face
Block is written, or generates the time of multiple blocks.It can not be easily accepted by a user completely.
In order to which the block chain for solving mentioned above is difficult to apply in the problems in current transaction, the present invention propose it is a kind of from
The block chain network transaction processing method of line node ensures not having to generate until block, even if propping up by building reconciliation mechanism
In the case of paying side offline, so that it may it is merchandised successfully with confirming, according to the mechanism of verification, about be can be completed within several seconds,
It is applied to abnormal transaction for block chain technology and provides support.
Below with reference to the accompanying drawings the block chain network transaction processing method of the offline node of the embodiment of the present invention is described.In order to retouch
The convenience stated, following embodiment concentrate on recipient's node side in block chain network on-line mode and are described, wherein place
The payment processing terminal, such as pos machines etc. of hotel owner are can be understood as in recipient's node of block chain network on-line mode.
Specifically, Fig. 3 is the block chain network transaction processing method of offline node according to an embodiment of the invention
Flow chart, as shown in figure 3, this method includes：
Step 101, Transaction Information is sent to sender's node in block chain network off-line mode, so that sender saves
Point generates current transaction record according to Transaction Information.
Wherein, Transaction Information includes transaction amount, tradable commodity, exchange hour, counterparty's trade name and loco etc., separately
Outside, sender's node in embodiments of the present invention can be understood as initiate payment behavior mobile terminal, such as smart mobile phone,
The hardware devices such as tablet computer, personal digital assistant, Wearable, the Wearable can be Intelligent bracelet, intelligent hand
Table, intelligent glasses etc..
It is emphasized that sender's node in block chain network off-line mode can be understood as current sender
Node can not achieve the real-time online in block chain network due to limitations such as electricity, flows, cannot function as stabilization in block chain and deposits
Node.
Specifically, recipient's node and sender's node send Transaction Information, so that sender's node is believed according to transaction
Breath generates current transaction record so that sender's node further confirms that the transaction, avoids other illegal mobile terminal camouflages
Sender's node initiates trading activity.
It should be noted that in order to realize the information exchange of sender's node and recipient's node, in block chain
Before sender's node of internet off-line pattern sends Transaction Information, recipient's node in block chain network off-line mode
Sender's node establishes communication network, so that recipient's node carries out information exchange by communication network and sender's node.
Wherein, according to the difference of application scenarios, communication network is established between sender's node and recipient's node
Mode may include infrared, bluetooth, NFC (Near Field Communication, near field communication (NFC)), WiFi,
Internet such as connects, scans the two-dimensional code at the face-to-face connection type, or by connection types such as third party's transfers (for example, receiving
Transaction Information is sent to third-party server by Fang Jiedian, and Transaction Information is sent to sender's node by third-party server).
Step 102, the current transaction record sent after sender's node signature is obtained, current transaction record is calculated
Cryptographic Hash, and cryptographic Hash is sent to the time stamp server of block chain network, so that time stamp server is cryptographic Hash label
Timestamp.
Step 103, the cryptographic Hash for including timestamp that is sent after time stamp server is signed is obtained, and to block chain
Web broadcast, and be stored in the trading pit that recipient's node does not generate block currently.
Specifically, sender's node confirms current transaction by way of signature, wherein according to the difference of application scenarios,
Sender's node can be signed by different identification informations, for example, sender device identification, networking license code etc., into
And after obtaining the current transaction record sent after sender's node signature, the cryptographic Hash of current transaction record is calculated, and
Cryptographic Hash is sent to the time stamp server of block chain network, so that time stamp server, which is cryptographic Hash, marks timestamp.
Pass through cryptographic Hash as a result, and by the timestamp label that time stamp server is cryptographic Hash label, marks current hand over
Easy uniqueness performs effectively convenient for currently merchandising in the execution mechanism of block chain.
In turn, the execution mechanism based on block chain is obtained in recipient's node and is sent after time stamp server is signed
The cryptographic Hash comprising timestamp after, to block chain network broadcast, know the transaction in order to all nodes of the block chain, just
In the trust authentication etc. for carrying out the transaction.
In some possible embodiments, when above-mentioned recipient's node and time stamp server carry out information exchange,
The mode of encrypted transmission may be used, for example, recipient's node will be sent to the time after private key encryption that cryptographic Hash passes through oneself
Server is stabbed, recipient's section is sent to after the private key encryption that time stamp server also passes through oneself to the cryptographic Hash comprising timestamp
Point etc..
The cryptographic Hash for including timestamp that will be sent after time stamp server is signed, it is current to be stored in recipient's node
In the trading pit for not generating block, it is to be understood that due to concurrent, trading volume huge and network of transaction etc.,
Node in block chain may have multiple blocks to generate task, wherein the block not generated is stored in current non-generation area
In the trading pit of block, the trading pit of recipient's node real-time update oneself in block chain is preserved in corresponding trading pit and is worked as
The preceding moment is to all transaction records for not having enough time being written block between the upper block generation moment, and basis is new in real time
It generates the transaction record being written into block to be deleted, and is added according to the New Transaction broadcasted in block chain.As a result,
In an embodiment of the present invention, will block chain network on-line mode be in due to sender's node, and will include without generate block
The cryptographic Hash of timestamp is stored in the trading pit that recipient's node does not generate block currently.
Step 104, the block chain account book that inquire-receive side's node currently preserves, obtains the last one block generated time,
And it is sent to sender's node from the last one block generated time to the Transaction Inquiries instruction timestamp.
Step 105, receive sender's node feeding back from the last one to occurring timestamp block generated time
First transaction record, and all the second transaction records related with sender's node are retrieved from trading pit.
Step 106, compare the first transaction record and the second transaction record, if comparison result is consistent, to sender's node
Send transaction confirmation message corresponding with current transaction record.
However, since sender's node in the embodiment of the present invention is in block chain network on-line mode, thus, using pair
The verification that account mechanism is currently merchandised.
Specifically, the block chain account book that inquire-receive side's node currently preserves first, when obtaining the generation of the last one block
Between, and sent to sender's node from the last one block generated time to the Transaction Inquiries instruction timestamp, to obtain
Sender's node is within the last one block generated time to the corresponding exchange hour of current time stamp, the All Activity row of generation
For.
Receive merchandising from the last one block generated time to first occurred timestamp for sender's node feeding back
After record, all the second transaction records related with sender's node are retrieved from trading pit, compare the first transaction record and
Two transaction records, to verify current transaction according to comparison result.
Wherein, if comparison result is consistent, show that current sender node is reliable, to be sent out to sender's node
Give transaction confirmation message corresponding with current transaction record, for example send " merchandising successfully " notification message etc..
If comparison result is inconsistent, if knowing that the first transaction record is less than the second transaction record for example, comparing, show
Sender's node has concealed part Transaction Information, to judge that sender's node is unreliable, is sent to sender's node and current
The corresponding transaction denied transmission of transaction record, for example, sending " Fail Transaction " notification message etc..
Certainly, in some possible embodiments, it is also possible to compare and know that the first transaction record is remembered more than the second transaction
Record then shows that the transaction record retrieval of possible current receiver node is not complete, retrieves all and sender again from trading pit
If related second transaction record of node carries out malfunction elimination, to ensure the block chain of present offline node still incomplete
Network trading handles the reliability of method.
Current trading activity is verified based on reconciliation mechanism as a result, is stored in the trading pit in recipient's node
Sender's node records (the second transaction record) from the last one block generated time to the All Activity timestamp, due to
Recipient's node can be broadcasted to block chain network, identify the cryptographic Hash for including timestamp each merchandised, thus, the second transaction note
It is contained in record from the last one block generated time to timestamp, sender's node and all recipients in block chain
The corresponding transaction record of trading activity of node.To the first transaction for feeding back second trading activity and sender itself
Record carries out reconciliation, and the reliability currently merchandised is determined according to reconciliation result.
That is, actually the present invention is to judge to merchandise to determine based on the degree of belief of sender's node, work as sender
When node is node trusty, it is determined that current transaction is reliable, when it is not node trusty to send hair node, it is determined that
Current transaction is unreliable.Wherein, in practical implementation, the first trading activity and the second trading activity include sender's node
In from the last one block generated time to the All Activity record timestamp, it may include that sender's node is in block chain
The transaction record of network on-line mode, and, sender's node is in the transaction record of block chain network off-line mode.Certainly, by
The transaction record that block chain network on-line mode is in sender's node had been verified, thus, in order to improve verification effect
Rate, the first trading activity and the second trading activity include sender's node from the last one block generated time to timestamp
All Activity record in, can include only that sender's node be in the transaction record of block chain network off-line mode.
In view of under some scenes, even if sender's node really states all transaction records, it is also possible to sender
Node does not have ability to pay, thus, amount of money and the means of payment in transaction record that can also be all to sender's node etc.
It is analyzed, determines sender's node either with or without ability to pay, for example, all trading activity amount of money of sender's node statement
It is all higher than the corresponding amount of money of current trading activity to be verified, and the means of payment is remaining sum payment, it is determined that recipient's node has
It is able to make payment, to confirm current trading activity.
For example, in current transaction to be verified, recipient's node in block chain network on-line mode is B, place
In sender's node of block chain network off-line mode be A, and from the last one block generated time in timestamp,
When node A is also that C has carried out transaction with recipient's node of block chain network on-line mode, as shown in figure 4, due to being in block
When node B and node C in chain are that node A is traded, it can be broadcasted in block chain, as a result, the transaction of node B
The transaction record of node A and node B are stored in pond, and, the transaction record of node A and node C.
When verifying the transaction record of node A and node B, node B sends from the last one block to sender's node A and gives birth to
At the time to the Transaction Inquiries instruction between the timestamp, according in the first transaction record and trading pit of node A feedbacks
The second transaction record, determine whether node A will feed back with the transaction record of node B and C, if node A really states institute
Some transaction records, it is determined that node A is reliable, to confirm to current transaction to be verified.
The block chain network transaction processing method of offline node of the present invention is in practical implementation, and equally there is also honeysuckles
The case where attack, the case where attack in order to avoid honeysuckle, in order to avoid sender's node from being completed twice using the same amount of money
Transaction, in an embodiment of the present invention, the transaction record based on multiple blocks is verified.
Specifically, Fig. 5 is the flow chart according to an embodiment of the invention for avoiding honeysuckle attack method, as shown in figure 5,
Before transaction confirmation message corresponding with current transaction record being sent in above-mentioned steps 106 to sender's node, this method packet
It includes：
Step 201, the block chain account book that inquire-receive side's node currently preserves obtains m-th block generated time,
In, m-th block is not the last one block, and is sent to sender's node from m-th block generated time to last one
Transaction Inquiries instruction between block generated time.
Step 202, receive sender's node feeding back slave m-th block generated time to a last block generated time
Between third transaction record, and from block chain account book retrieval from m-th block to a last block is all and sender
Related 4th transaction record of node.
Step 203, compare third transaction record and the 4th transaction record, if comparison result is consistent, to sender's node
Send transaction confirmation message corresponding with current transaction record.
In order to avoid honeysuckle is attacked, reconciliation, in an embodiment of the present invention, base are carried out to a large amount of transaction of sender's node
In from m-th block to the generated time of a last block, all trading activities of sender carry out reconciliation, wherein M is arrived
The time interval of the last one block is bigger, i.e., M is smaller, then the result of reconciliation is more reliable.
Specifically, the block chain account book that inquire-receive side's node currently preserves obtains m-th block generated time, wherein
Based on the generting machanism of block chain, each block has the timestamp generated, therefore, it is possible to be based on this execution mechanism, obtains
To m-th block generated time, sent from m-th block generated time to a last block generated time to sender's node
Between Transaction Inquiries instruction.
Receive sender's node feeding back slave m-th block generated time to a last block generated time
Three transaction records, and retrieval is all related with sender's node from m-th block to a last block from block chain account book
The 4th transaction record, compare third transaction record and the 4th transaction record, if comparison result is consistent, show sender's node
Reliably, there is the ability to current transaction payment, to which it is true to send transaction corresponding with current transaction record to sender's node
Recognize message.
In order to more comprehensively description the embodiment of the present invention offline node block chain network transaction processing method, below
It illustrates, is described as follows in conjunction with specific application scenarios：
Wherein, in this example, the sender's node for being in block chain network off-line mode is node A, is in block chain
Recipient's node of network on-line mode is node B, and in current trading activity to be verified, node A needs payment 5 to node B
Member, node A and node B are connected by bluetooth approach.
As shown in fig. 6, after node A is connected with node B, address informations of the node B to node A sending nodes B, transaction amount
Equal Transaction Informations, node A is signed according to the Transaction Information and generates transaction record, and transaction record is fed back to node B.
Node B calculates the cryptographic Hash of the transaction record, and the cryptographic Hash of the transaction record is submitted in block chain network
Time stamp server, after time stamp server has received the cryptographic Hash, which is stamped to the timestamp at current time, use
Node B is sent to after the private key signature of oneself.
Node B obtains the hash value that timestamp is stamped by time stamp server of the transaction, and node B is by usage time
The cryptographic Hash and timestamp for stabbing the transaction after the private key signature of server are broadcast in block chain and are issued.
Node B retrieves All Activity related with node A simultaneously from the trading pit for not generating block currently and records (the friendship
Every record in Yi Chi is required for verifying signature), and these transaction records are in chronological sequence ranked up, and root
Reconciliation is carried out according to the All Activity record of A, is carried out if success in next step, otherwise payment failure.
Specifically, node B inquires the block chain account book oneself locally preserved, the last one before current time is obtained
The generated time of block, then the generated time to Node A requests from the last one block have joint to current exchange hour
Whole transaction records of point A i.e. the first transaction record (record for including offline and online two kinds of modes of doing business).Node B is by node
A, which is sent in oneself the first transaction record and trading pit, has the second transaction record of artis A to be compared, if unanimously,
And thinking that node A has the ability to pay the amount of money by calculating, then node B confirms this transaction.
If the first transaction record of node A statements is less than the second transaction record about A in node B trading pits, to A
Statement, this payment failure.If the first transaction record of node A statements is more than the second transaction about A in node B trading pits
Record, then the record progress reconciliation again that node B is provided according to node A.Likewise, node B attacks in order to avoid honeysuckle, it can be with
It compares and confirms transaction record all in the M block of current transaction moment forward, carry out reconciliation, determined according to reconciliation result
