In the scheme, the problem that settlement is not always strictly carried out according to real-time international exchange rate due to different settlement rates of different financial institutions in cross-border transactions is solved by establishing the exchange rate priority list. The problem that exchange is not strictly carried out according to the international exchange rate in different entrance institutions, and therefore the exchange rate of an initiator and the exchange rate of a receiver are different during transaction, and transaction failure is caused is solved.
Description
Technical Field
The invention relates to a settlement method, in particular to a cross-border payment settlement method based on a block chain payment system.
Background
The cross-border settlement means that the import and export enterprises do not have obvious feeling except for changing from adopting local currency credit to adopting foreign currency credit, and the real change is in the background settlement part between internal and external banks. For example, in the negotiation process with the overseas buyer, an export enterprise in china may request the renminbi to settle, and the overseas buyer opens a renminbi letter of credit at the payment bank and then negotiates with the buyer by the payment bank, and then sends, receives, and pays the goods, etc.
There are two modes of operation, agent mode and clearing mode, for commercial banks to conduct cross-border settlement business. The proxy mode is a mode that a middle resource line entrusts an external resource line as a proxy line in overseas, and overseas enterprises set up RMB accounts in the entrusting line of the middle resource enterprise; the clearing mode is mainly the business between the main line and the overseas branch line in the medium resource line, that is, the overseas enterprise sets up the RMB account outside the medium resource line.
The conventional cross-border payment settlement background is complex, the data volume is large, the bank can only settle accounts generally, and the settlement is inconvenient. Meanwhile, different entrance institutions do not necessarily exchange the data strictly according to the international exchange rate, so that the exchange rate of the initiator and the exchange rate of the receiver are different during transaction, and the transaction fails.
Disclosure of Invention
The invention aims to solve the technical problem that different entrance institutions do not necessarily and strictly exchange according to international exchange rates, so that transaction failure can be caused by different exchange rates of an initiator and a receiver in transaction.
The invention is realized by the following technical scheme:
the cross-border payment settlement method based on the blockchain payment system comprises a plurality of financial service institutions and further comprises the following steps:
A. establishing a payment system based on an industry block chain, wherein each financial institution is positioned on the block chain as an independent node, and all nodes of the industry block chain designate a plurality of nodes as bookkeepers; establishing an exchange rate priority list among the financial institutions;
B. when transaction data are generated, a node initiating transaction initiates a request according to the exchange rate of the node, a new transaction data block is requested to be created, and the transaction data block is broadcasted to all the accountants on the block chain by the industry block chain;
C. b, the bookkeeper reads the exchange rate priority list established in the step A to verify the requested transaction data block, judges whether the exchange rate is correct or not, if so, enters the step E, otherwise, enters the step D;
D. rejecting the request in the step B, sending error information to a node initiating the transaction, reading the exchange rate of the node receiving the transaction by the node initiating the transaction, initiating a request according to the read exchange rate, requesting to create a new transaction data block, broadcasting the transaction data block to all bookkeepers in the block chain by the industry block chain, and then transferring to the step C;
E. the node that initiated the request adds the transaction data block to the main chain of the industry block chain.
The scheme is based on a blockchain technology, an industry blockchain means that a plurality of preselected nodes are designated as bookkeepers in a certain group, the generation of each block is determined by all the preselected nodes together, and other access nodes can participate in transactions without inquiring about a billing process. In the scheme, the problem that settlement is not always strictly carried out according to real-time international exchange rate due to different settlement rates of different financial institutions in cross-border transactions is solved by establishing the exchange rate priority list.
The consensus mechanism of the bookkeeper adopts a DPoS mechanism. The DPoS mechanism further reduces the number of the nodes to 101, so that the energy consumption of the whole network is further reduced on the premise of ensuring the network security, and the network operation cost is lowest. The DPoS mechanism is more decentralized. The DPoS mechanism also has faster acknowledgement speed. Each block is 10 seconds in time, one data exchange, i.e. about 1 minute for 6-10 acknowledgments, and a complete 101 block period of only about 16 minutes. Whereas the PoW mechanism takes 10 minutes to generate a block and 1 hour for one data exchange. The PoS mechanism also requires approximately 1 hour to confirm a transaction. Shorter transaction times are required because the transaction duration of the PoW mechanism and PoS mechanism is longer, while the exchange rate fluctuates in real time.
The information recorded in the transaction data block includes a transaction initiator, a transaction recipient, an initiator monetary amount, a recipient monetary amount, an exchange rate, and a timestamp.
The method for checking in the step C comprises the following steps:
c1, the bookkeeper reads the exchange rate priority list established in the step A to verify the requested transaction data block, and judges the exchange rate priority of the node initiating the transaction and the node receiving the transaction;
c2, extracting the exchange rate information of the higher priority node in the node initiating the transaction and the node accepting the transaction, judging whether the exchange rate information is consistent with the exchange rate information recorded in the transaction data block requested in the step B, if so, entering the step E, otherwise, entering the step D.
By adopting the method, the priority list is used for judging the priority sequence of the initiating node and the receiving node, and the mixing rate of the nodes with higher priorities is selected as the exchange rate of the transaction.
And C, when the biller reads the exchange rate priority list established in the step A to verify the requested transaction data block, the biller also verifies the identity of the initiating node of the transaction data block.
The identity verification method comprises the following steps:
f1, matching a unique verification password for each node, and packaging the verification passwords of all nodes as a verification program;
f2, when the node generating the transaction initiates a request, the node sends the externally input verification password to each bookkeeper at the same time;
f3, the bookkeeper passes the verification password sent by the verification node of the verification program, if the verification password is consistent with the password recorded in the verification program, the verification is passed, otherwise, the verification is not passed. The security of the method is effectively improved by encrypting the verification password.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. according to the cross-border payment settlement method based on the block chain payment system, the block chain system is simple and convenient to build;
2. the cross-border payment settlement method based on the block chain payment system effectively solves the problem of different exchange rates among different financial institutions;
3. the cross-border payment settlement method based on the block chain payment system has an independent encryption module and is higher in safety.
