The circulation number that operation serial number is used to identify the credits information is stated, to guarantee the orderly progress of subrogation.For example, for
For six subrogation information, operation serial number can be 5.
Optionally, the 6th subrogation information can also include the business private key of third user to the 6th subrogation
The signature of above- mentioned information in information, for example, when the 6th subrogation information includes：Credits holder's information is third use
Family, credits recipient's information are sky, and the credits state in the 6th subrogation information is that serial number is closed and operated to credits
When with the information such as NextState operation side, server can be according to the business private key of third user to signing, and will signature
It stores to the 6th subrogation information, to guarantee the authenticity of data.
219, server stores the credits key assignments and the 6th subrogation information to the block catenary system
On block chain.

Move information, generate the 6th block, and known together in block catenary system to the 6th block and know together by when, by the 6th block
It is added on the block chain of the block catenary system.
It should be noted that at any time, if receiving the credits inquiry instruction of any user, receiving any user
Credits inquiry instruction, the credits inquiry instruction carries the credits key assignments；The credits key is inquired from the block chain
Value, determines at least one block；The subrogation letter that will be stored in the highest block of block height at least one described block
Breath is sent to the user.By the query process based on block chain, the last state of credits can be inquired, to avoid by
In Asymmetry information etc. and caused by maloperation situations such as occur.
Certainly, in inquiry, the subrogation information stored at least one block can also be returned to user, with
Just user is made to know the variation overall process of the credits.

Speed.By taking above-mentioned financing process as an example, the logic which is realized may refer to be created shown in Fig. 4 by debt side
After debt, the state of credits is established for credits, and when receiving the notification of the assignment of credits, it is logical that credits state is updated to the assignment of credit
Know, if recalling transfer, the state of credits reverts to credits and establishes, and in the state of assignment of credit notice, if received
Confirm that then the state of credits is updated to assignment of credit Notification Validation, if recalling confirmation, the state of credits is extensive to notification of the assignment
It is established again for credits, and in the state of assignment of credit Notification Validation, if it is confirmed that having beaten money, then the state of credits is updated to
Credits holder is paid, and when credits holder receives fund, then credits state is that credits are established, and credits at this time return the
Tripartite is all, and in the state that credits are established, if credits holder at this time acknowledges receipt of fund, credits state updates
For credits closing.The logic can realize that detailed process is detailed in stream shown in Fig. 2 jointly by operation system and block catenary system
Journey, details are not described herein.

Company A, serial number 0 is operated, while being signed with the business private key of B enterprise to above data.
(2) A enterprise needs more fund flows, and above accounts receivable is prepared to transfer factoring quotient C.A enterprise for
Corresponding accounts receivable stores the following contents on block chain：The essential information (constant) of debt, it is A, debt that credits, which hold company,
Power acquiring company becomes C, and credits Status Change is assignment of credit notice, and it is debt company B that NextState, which operates company, operates sequence
Number 1, while being signed to above data with the business private key of A enterprise.
(3) B enterprise need to obtain the debt call announcement of A, C, and confirm transfer.B company can inquire corresponding credits
Key assignments, if this debt has been given back, just initiates withdrawal operation to know the state of debt.And if B corporation loan
It does not give back, then can agree to that debt shifts, store the following contents on block chain：Debt essential information, credits hold company
For A, credits acquiring company is C, and credits Status Change is assignment of credit Notification Validation, and NextState operates company as credits reception
Company C operates serial number 2, meanwhile, it is signed to above data with the business private key of B enterprise.
(4) C enterprise makes loans to A, and A is by the assignment of credit to C.C can inquire corresponding credits key assignments, to know debt
State confirms that this credits enters transfer of obligation Notification Validation.At this point, C can recall this if being not desired to receive the transfer of this debt
Operation.If C company agrees to receive the transfer of this debt, it can make loans to A, store the following contents on block chain：Debt
Be basically unchanged, it is A that credits, which hold company, and credits acquiring company is C, and Status Change is beat money to hold company, and NextState is grasped
Making company is that credits hold company A, operates serial number 3, meanwhile, it is signed to above data with the business private key of C enterprise.
(5) A can inquire corresponding credits key assignments, to know the state of debt, confirm that this debt number enters payment
After credits holder, by subrogation, the following contents is stored on block chain：The essential information of debt, credits hold company
Become credits acquiring company C, it is C that NextState, which operates company, and credits acquiring company is sky, and Status Change is established for credits, behaviour
Make serial number 4, meanwhile, it is signed to above data with the business private key of A enterprise.
(6) B enterprise refunds to C.When B enterprise refunds, corresponding credits key assignments can be inquired, to know debt
State beats money to holder when confirmation current state is that credits are established just now.
(7) after C receives corresponding fund, the following contents is stored on block chain：：The essential information of debt, credits are held
Company is C, and it is sky that NextState, which operates company, and credits acquiring company is sky, and Status Change is credits closing, operates serial number 5,
Meanwhile it being signed to above data with the business private key of C enterprise.
In the above process, the inquiry of bill and account receivable and state circulation are very convenient, greatly accelerate factoring financing
Efficiency.Meanwhile the data of cochain can not distort, and greatly ensure that the authenticity of accounts receivable.The modification of data after cochain
