Fig. 2 diagrammatically illustrates the flow chart of the method for bill circulation according to the embodiment of the present disclosure.This method is answered
For block chain network, block chain network includes the first sub-network and the second sub-network, and the first sub-network includes and multiple bills
The corresponding multiple first nodes of platform are transferred the possession of, include master (Leader) node of the first sub-network in multiple first nodes, second
Sub-network includes multiple second nodes corresponding with multiple discounted note banks, and more specifically, this method is applied to the first son
The host node of network.
As shown in Fig. 2, this method is included in operation S201, the billing information from the side of taking ticket is received.
Wherein, the above-mentioned side of taking ticket refers to the current client as the side of taking ticket, and currently the side of taking ticket is in multiple client
One, the user of the current client as the side of taking ticket is the user for currently holding bill.For example, multiple client includes client
A, customer end B and client C are held, when bill is held by the user of customer end A, customer end A is used as the side of taking ticket, when bill is by visitor
When the user of family end A transfers the user of customer end B, the side of taking ticket is changed to customer end B from customer end A, it can be seen that the side of taking ticket
This role likely corresponds to different clients in different times.This operation S201, which is received, is used as the side of taking ticket from current
Client billing information, when a client as the side of taking ticket to the host node of the first sub-network issue billing information
When, illustrate that the user of the client as the side of taking ticket wishes to transfer the possession of corresponding bill, the billing information for describe the bill from
Generate the relevant information until current time.
In operation S202, the billing information is broadcasted to first sub-network, by one in first sub-network
A or multiple first nodes are to billing information described in the multiple client push.
Wherein, the host node of the first sub-network broadcasts the billing information from the currently side of taking ticket into the first sub-network
One or more first nodes, any first node can be stored after receiving the billing information locally, and should
Billing information pushes to client corresponding with the first node, and then the user of relative client can be known and bill letter
It ceases corresponding bill and is in the relevant informations such as state to be transferred the possession of, the side of taking ticket, historic state.To other visitors other than the side of taking ticket
The user at family end when needed can be to request bill transfer at the user for currently holding bill.
In operation S203, it is changed in response to the side of taking ticket by one client another in the multiple client
One client obtains characterization bill and circulates from one client to the transaction record of another client and carry out first
Verifying generates the block comprising the transaction record after being verified first；The block is sent to second subnet
Network carries out the second verifying, and the block is added to block chain after being verified second.
Wherein, when bill transfers the user of customer end B by the user of customer end A, the side of taking ticket is changed to from customer end A
Customer end B, that is, the side of taking ticket are changed to the event of another client by a client.At this point, according to this operation S203, the
The host node acquisition of one sub-network characterizes the bill and circulates from customer end A to the transaction record of customer end B, and to the transaction record
Progress first is verified, if indicating to primarily determine that bill circulation process is very, to generate and remember comprising the transaction by the first verifying
The block of record.The block is sent to the second sub-network being made of bank node and carries out the second verifying, if tested by second
Card indicates finally to determine that bill circulation process is very, in the block chain that block addition block chain network is safeguarded.Into one
Step ground, after operating S203, customer end B is as the current side of taking ticket, if the user of customer end B wishes to continue to transfer the possession of the ticket
According to, repeat aforesaid operations S201~S203, until bill circulation process terminate.
As it can be seen that method shown in Fig. 2 devises the block chain network comprising the first sub-network and the second sub-network, wherein the
Each node in one sub-network corresponds to bill and transfers the possession of platform, and each node in the second sub-network corresponds to bank.Pass through first
Sub-network notifies the transfer demand of bill to each client, and when bill circulation process occurs, corresponding transaction record is passed through
Block chain can be just stored in by crossing after the double verification of the first sub-network and the second sub-network, guarantee transaction data it is true, safe, with
And nothing is distorted, and each side of block chain network and each client that can be communicated with block chain network being capable of timely learning bills
The latest tendency and relevant information of circulation improve the efficiency of bill circulation process.
In one embodiment of the present disclosure, above-mentioned billing information may include: summary info, content information, Yi Jizuo
For the digital signature of the said one client of the currently side of taking ticket.Wherein, the summary info of billing information includes following at least one
: the amount of the instrument, the side's of drawing a bill identification information and the side's of taking ticket identification information.Specifically, it endorses in current bill through the side of honouring
In the case of, corresponding summary info further includes the side's of honouring endorsement information.There are the previous side of taking ticket, summary info
It further include the endorsement information of the previous side of taking ticket.And/or the content information of billing information includes at least one of following:
Bill encryption information, the account information for the side of drawing a bill, the side of taking ticket account information and coupon identification information, wherein bill encrypt
Information includes allowance interest rate information of bill etc..
For example, customer end B generates bill 1, draw a bill side of the customer end B as bill 1, currently by the user of customer end A
Hold the bill 1, then customer end A is as the current side of taking ticket.Customer end A generates the process of the current bill information of bill 1 are as follows: visitor
Family end A generates the triple (bill encryption information, the account information for the side of drawing a bill, the account information for the side of taking ticket) about bill 1.Its
In, bill 1 is electronic bill, and bill linking sources are circulation object, and bill encryption information refers to the interest rate information of bill allowance,
It needs to encrypt；Summary info of the side of taking ticket to triple editor's plaintext, comprising: the amount of the instrument, the side's of drawing a bill title and take ticket
Square title, while the billing information is signed by the side of taking ticket using the private key of itself, and the digital signature comprising the side of taking ticket is obtained
Billing information, the message comprising the billing information is broadcast to the first sub-network.
In one embodiment of the present disclosure, above-mentioned broadcast the billing information to the first sub-network may include: to test
Demonstrate,prove the true and false of the billing information；And if the billing information be it is true, which is broadcasted each to the first sub-network
First node is to be stored.
For example, currently as the first sub-network host node bill transfer platform can under chain by with it is existing general
E-business draft system (ECDS) interaction, complete verifying to the taken ticket evidence in the currently side of taking ticket, i.e., completion is to corresponding bill
The verifying of information, if verification result shows that the billing information is true, and verification result write-in is issued by the currently side of taking ticket
Billing information generates four-tuple (bill encryption information, verification result, the account information for the side of drawing a bill, the account information for the side of taking ticket),
The bill transfers the possession of platform using the private key of itself to information signature ((bill encryption information, verification result, the account for the side of drawing a bill
Information, the account information for the side of taking ticket), bill transfers the possession of the digital signature of platform), and by the message to the first sub-network other are each
First node broadcast, so as to each client push message.
It in one embodiment of the present disclosure, include a host node in multiple first nodes of the first sub-network, referred to as
For platform Leader node.It also include a host node, referred to as bank Leader in multiple second nodes of second sub-network
Node.Wherein optionally, the platform Leader node in a period of time in office is by the side of taking ticket in any time period
Specified.And/or bank's Leader node in any time period is determined based on RAFT common recognition algorithm.
As it can be seen that the first sub-network determines that the mode of host node is different from tradition RAFT common recognition algorithm, platform Leader node
It is specified by the side of taking ticket, rather than elected from candidate (Candidate) node.I.e. bill business occurs at which
Bill transfers the possession of platform, just transfers the possession of the corresponding first node of platform as current platform Leader node by the bill and is remembered
Account, other first nodes in the first sub-network are used as from (Follower) node, corresponding to the bill for being in nontransaction state
Transfer the possession of platform.
And the second sub-network determines that the mode of host node is largely consistent with tradition RAFT common recognition algorithm, such as bank
Selection, conversion of state of Leader node etc. are by electing.But this is in order to improve according to the embodiment of the present disclosure
The safety of scheme for bill circulation, needing to avoid the occurrence of the corresponding second node of some bank is bank Leader always
The case where node, so avoid book keeping operation power too concentrate, as an optional embodiment, this programme devise as follows with biography
The different part of system RAFT common recognition algorithm: when the host node of second sub-network in the two neighboring time cycle is same section
When point, host node is determined from second sub-network based on RAFT common recognition algorithm again.The process can be referred to as are as follows:
Leader life cycle management.For example, each T time section, carries out the starting of bank's Leader node selection mechanism, so that
In the book keeping operation of each platform Leader node, the bank's Leader node for synchronizing book keeping operation is different, if the bank selected
Leader node delay machine, re-elects, until generating qualified bank's Leader node.In order to avoid practising fraud, if
In two adjacent T, the corresponding node of same bank is selected as bank's Leader node twice in succession, then is considered as electoral adoidance,
RAFT common recognition algorithm is restarted, until selecting legal bank's Leader node.
On this basis, in one embodiment of the present disclosure, then the host node of above-mentioned first sub-network by the packet of generation
Block containing transaction record is sent to the second sub-network and carries out the second verifying, and the block is added to area after being verified second
Block chain may include: the host node that the block is sent to current second sub-network, by the host node of the second sub-network to the area
Block carries out the second verifying, and the second verification result is added in the block；And the block comprising the second verification result is added
Enter to the block chain.
The above process is related to the communication between platform Leader node and bank's Leader node, for example, the communication can be with
It is issued from platform Leader node to bank's Leader node, Content of Communication is " synchronous account book ", and bank's Leader node receives
After the request, start block chain distribution account book synchronization mechanism, the synchronizing content that platform Leader node is sent is added to
Have in account book.Since the circulation process of multiple bills may be handled simultaneously in the first sub-network, with having in a period of time
Multiple clients as the side of taking ticket, multiple bills transfer the possession of the platform Leader section that platform is designated as different bill circulation processes
Point keeps the platform Leader node of heartbeat all being traded and kept accounts.Therefore, can exist multiple platform Leader nodes with
Bank's Leader node synchronizes the case where account book simultaneously, and bank's Leader node is both needed to locate for any request received
Reason starts hot standby server at once and completes link work if delay machine.
Specifically, in one embodiment of the present disclosure, the first sub-network further includes the first hot standby node, when the first subnet
When the host node of network breaks down, the host node of first sub-network is replaced using the described first hot standby node.And/or
