Detailed Description
The embodiment of the application provides ordering and settling method and device based on a block chain.
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a block chain based ordering method according to an embodiment of the present application.
S101, inquiring whether the transaction is related to a preposed transaction.
The query is made as to whether the transaction is associated with at least one preceding transaction, preferably the transaction comprises a list for storing a hash of the preceding transaction, which is used by the blockchain to find the corresponding preceding transaction.
Wherein the transaction includes an amount due.
The pre-transaction, which receives payment to be used for the transaction, is a post-transaction of the pre-transaction, the pre-transaction and the post-transaction being interdependent. When processing the transaction, the prefix amount is the amount used to pay for the transaction in the amount of the prefix transaction, each of which has its own prefix amount. The post total amount of the pre-transaction is the sum of the amounts of all the post transactions of the pre-transaction for paying the post transactions by using the amount in the pre-transaction, wherein the pre-amount of the transactions is included.
S102, all the prepositive transactions are detected.
Detecting each of said pre-transactions if said transaction is associated with at least one of said pre-transactions, said detecting comprising ensuring that the sum of said pre-amount of said pre-transaction for said transaction and said post-total amount thereof is not greater than its amount due, and rejecting said transaction if said detecting reports an error.
Optionally, if repeated hashes appear in the list storing the pre-transaction hashes, an error is detected and the transaction is rejected.
Optionally, if a transaction corresponding to a hash in the list storing the pre-transaction hashes does not exist, an error is detected and the transaction is rejected.
Wherein the preceding transaction of the transaction must be an unpaid transaction whose amount is not immediately paid to its recipient, but a subsequent checkout transaction is initiated to complete the corresponding payment. When the transaction is in an unpaid state, the prepaid for the transaction is stored on the blockchain but not paid to the recipient of the transaction. And if the transaction corresponding to a certain hash in the list storing the pre-transaction hashes is not an unpaid transaction, detecting error report and rejecting the transaction.
Wherein said amount due should equal a prepaid amount for said transaction plus said sum of said premiums for all of said premiums for said transaction, and if no error is detected, said transaction is rejected.
Wherein, when the amount due for the transaction is greater than the lead amount of all the lead transactions of the transaction, the transaction must pay a pre-payment additionally by a difference between the amount due for the transaction and the sum of the lead amounts of all the lead transactions of the transaction. This enables the initiator of the transaction to create a transaction with an amount due greater than the sum of the antecedent amounts of all of the antecedent transactions.
Preferably, the initiator of the transaction must be or obtain authorization of the recipient of the pre-transaction to use the pre-transaction.
Optionally, the receiver of the pre-transaction authorizes the pre-transaction to the initiator of the transaction by initiating a one-time authorization transaction.
Optionally, the receiver of the pre-transaction authorizes the initiator of the transaction to use the transaction of which all receivers are the receivers of the pre-transaction as the pre-transaction.
Preferably, the block chain caches the authorization information, so as to conveniently inquire the authorization.
Preferably, the initiator of the transaction must obtain authorization of the recipient of the transaction to create the transaction using the ordering method. Since the checkout conditions of the transaction created by the method often involve checkout of a preceding transaction, the time for waiting for checkout is long, and some accounts often cannot accept the transaction created by the method when fund turnover is urgently needed, the transaction initiator acquires authorization of the transaction receiver before the transaction is created by the method.
Optionally, the recipient of the transaction authorizes a single transaction that is allowed to be created by the originator of the transaction using the ordering method.
Optionally, the recipient of the transaction authorizes all of the transactions that the originator of the transaction is allowed to create using the ordering method.
Optionally, the recipient of the transaction authorizes the transaction that is allowed to be created by all accounts using the ordering method.
S103, the transaction is linked up, and the post total sum of all the pre-transactions is updated.
And updating the post total sum of all the pre-transactions of the transactions simultaneously during the uplink transaction, so that the post total sum of the pre-transactions can be directly obtained without traversing the whole block chain when the transaction is established next time by the method.
The initial value of the post-total amount of any unpaid transaction is 0, and the post-total amount is not stored when the post-total amount is 0.
Fig. 2 is a schematic diagram of a block chain-based checkout method according to an embodiment of the present application.
S201, confirming whether the transaction to be settled is related to the post transaction.
Determining whether a transaction to be settled is associated with at least one post transaction, wherein the transaction is to be paid for the post transaction, the transaction being a pre-transaction of the post transaction. The post-amount is the amount of the transaction that is used to pay for the post-transaction.
S202, if the post transactions are related, all the post transactions are searched recursively.
If the transaction is associated with at least one post transaction, recursively searching all the post transactions of all the post transactions.
Specifically, all post-transactions of the transaction are searched first; and then searching all post-transactions for all the post-transactions, and going down in this way until the searched post-transactions are not associated with any post-transactions.
Preferably, a cache is constructed on the blockchain node and used for storing a hash list of post-transactions of the transactions, so that the efficiency of recursive search can be optimized.
S203, the amount is distributed recursively, and the rest is distributed to the receiver of the transaction.
Wherein the amount of the transaction to be settled is recursively allocated, and the remainder is paid to the recipient of the transaction.
When the amount is distributed recursively, if the post-transaction is already settled, the corresponding amount does not need to be distributed to the post-transaction, and the amount is paid to the receiver of the corresponding pre-transaction.
Specifically, firstly, the remaining part of the transaction is obtained by subtracting the post total amount of the transaction from the amount due to the transaction, then whether all the post transactions of the transaction are in an unpaid state is detected, if the post transactions are not in an unpaid state, the remaining part of the transaction is added with the pre amount of the post transaction used by the post transaction, after the traversal is completed, the remaining part of the transaction is clearly calculated, and finally the remaining part of the transaction can be paid to a receiver of the transaction, wherein the allocated amount of each unpaid post transaction is the pre amount of the post transaction used by the post transaction. At this time, the amount of the transaction is allocated, and the state of the transaction is changed into the settled state.
Next, all of the outstanding post transactions of the transaction are traversed. Optionally, since the post-transaction may also depend on other pre-transactions, there may be an outstanding transaction in other pre-transactions, and it is necessary to wait for the post-transaction to be processed when all the pre-transactions of the post-transaction are settled. And if the state of all the front transactions of the back transactions is not checked out, temporarily not distributing the front transactions. And if the states of all the front transactions of the back transactions are settled, and the back transactions do not need to wait for settlement of other front transactions any more, directly distributing according to the distribution scheme of the transactions. In this way, until the found post transaction is not associated with any post transaction or a state in all of the found pre transactions of the post transaction is not checked out.
It is emphasized that if a transaction does not have the post-transaction, the post-total amount for that transaction is 0.
Preferably, in the recursive traversal process, if the states of all the front transactions of the back transactions are settled, the state of the back transaction is updated to be settled.
