Description

 Transnational trading system using blockchain technology and method thereof  

The present invention relates generally to cross-border transactions, and in particular to cross-border transaction systems and methods thereof using blockchain technology.

Traditional cross-border transactions usually require a letter of credit developed by the bank. The so-called development letter refers to the bank accepting the client's entrustment to issue a letter of credit, notifying and authorizing the designated beneficiary (such as the seller), after fulfilling the agreed conditions, according to certain conditions. To develop a draft or other vouchers within a certain amount, and the bank or its designated bank is responsible for the credit method of acceptance or payment. The general letter of credit can be divided into immediate payment or forward payment. The former is the seller prompting all the documents, the bank will pay immediately, if the financing is open, the bank financing interest will be paid immediately; if the latter is the seller after the delivery of the documents The bank waits until 30 days or the number of days requested by the buyer before paying the seller. In the case of a spot letter of credit, it takes about 7 to 14 days from the buyer’s reminder to the billing bank to receive the payment, because both banks need to transfer the amount through the foreign banks. slower. The buyer is required to pay the opening fee (ie, postage and electricity plus bank charges). Generally, if the transaction is not with the bank for a long time or if there is a real estate mortgage, an additional deposit must be paid. The amount of the opening fee will vary depending on the amount of your letter of credit.

In addition, the letter of credit must also be insured against water insurance. In addition to the foreign currency account, the buyer must apply for an open credit with the bank, which is a collateral financing or personal credit. If the buyer does not apply for the opening quota, then the cash is opened. For example, if the buyer wants to open a letter of credit of US$5,000, the buyer must first pay US$5,000 to the bank, and the bank will help the buyer. Give a letter of credit to the other party. If the application for financing is open, the general bank will set the upper limit of the amount that the buyer can use. If the buyer is not able to use it, it can cooperate with the cash opening method mentioned above. The letter of credit has a greater protection for the buyer, because the buyer can meet the special requirements, such as the time of shipment, quantity, quality, etc., will be honored, and the general cost is higher.

However, the letter of credit has several drawbacks. For example, although it is the fastest spot letter of credit, it takes one to two weeks from the bid to the payment, and the bidding time is lengthy. The buyer is required to pay the opening fee, the guarantee, and the water insurance. If the application is not open, but the cash is opened, it must be held in cash to handle a considerable amount of credit, so the bidding cost is quite high. If you are applying for financing, you will have a quota limit. If it is not enough, you still need to use cash. In addition, many physical paperwork is required and there is a problem with file copying.

Therefore, there is still a need for a technical solution that can solve the problems of long time of bidding and high bidding cost of the above-mentioned traditional letter of credit.

In order to overcome the problems of the above-mentioned traditional letter of credit, such as lengthy bidding and high bidding cost, the present invention provides a transnational transaction system using blockchain technology and a method thereof.

In one aspect of the present invention, the present invention provides a cross-border transaction system using blockchain technology for at least one electronic device, wherein the transnational transaction system includes at least one transaction module for conducting a transaction; at least one The transceiver module is coupled to the at least one transaction module for transmitting and receiving data of the transaction; a blockchain network coupled to the at least one transaction module for recording transaction data; and a verification module, Coupling the blockchain network; and a scanner coupled to the verification module, when the transaction item arrives at the country where the buyer is located, the scanner scans the bar code on the transaction product and transmits the bar code information to The verification module is configured to facilitate the verification module to verify whether the transaction commodity belongs to a smart contract signed between a seller and the buyer through the blockchain network, wherein the seller is located in a different country from the buyer.

In another aspect of the present invention, the present invention provides a cross-border transaction method using blockchain technology, the method comprising: a first transaction module transmitting a seller's sales demand to a blockchain network; a second transaction module transmits a purchase request of the buyer to the blockchain network; if the sales demand matches the purchase requirement and is authenticated by the blockchain network, the seller signs an intelligence with the buyer The contract is to establish a transaction; the seller sells a transaction commodity by sea or air; when the transaction goods arrive at the country where the buyer is located, a scanner scans the barcode on the transaction commodity and transmits the information of the barcode to the first a verification module; the verification module verifies, by the blockchain network, whether the transaction commodity belongs to a transaction represented by the smart contract stored in the blockchain network; if yes, the transaction is performed by an electronic payment system The payment for the merchandise is paid to the account of the above seller; and if not, the transaction fails and the above electronic payment system does not pay the seller Households, the above transaction the seller return the merchandise to the above, wherein said seller and buyer above in different countries.

One advantage of the present invention is that the present invention can be used for cross-border transactions without the use of a letter of credit.

The transnational trading platform, through the trading module, the seller 10 and the buyer 20 can conduct transactions on the goods with each other. In an embodiment, each of the transaction modules 141, 142 corresponds to a transceiver module 111, 121. The transaction module 141, 142 can be connected to the blockchain network 150 by a transceiver module, and transmitted or Receiving a transaction or information related to the transaction, the transceiver module here may be a software and hardware for transmitting and receiving data.

Referring to the description of the first figure, in one embodiment, the blockchain network 150 is a network using blockchain technology. Blockchain is a distributed repository. The blockchain uses cryptographic methods to generate data blocks. Each data block contains transaction information that can be used to verify the validity of its messages (anti-counterfeiting) and is held by most nodes in the network. Therefore, the blockchain network 150 is a notebook that can record all transnational transaction data, has the characteristics of multiple nodes, and cannot be modified by anyone, so it can be a complete encryption method of data and data, and can strengthen transaction security.

The blockchain network 150 will connect all transaction modules, each transaction data will be recorded on the blockchain network 150, and the verification module 161 can verify the transaction from the data recorded on the blockchain network. commodity.

Referring to the description of the second figure, a schematic diagram of a transnational transaction system 200 using blockchain techniques is illustrated in accordance with an embodiment of the present invention. In this embodiment, a multinational transaction system 200 using blockchain technology is employed for at least one electronic device 210, 220. In one embodiment, a vendor 10 transmits a sales request 201 to the blockchain network 250 via the transceiver module 211 and the transaction module (seller) 241. The contents of the sales request 201 may include photographs, product names, specifications, models, quantities, shipping methods, brief or detailed descriptions of the products to be sold. The vending demand 201 can be stored or recorded in the transaction module (seller) 241 of the seller 10. The seller 10 may search the blockchain network 250 for other sales or purchase requirements via the transaction module (seller) 241, such as the purchase request 202 of the second figure. In yet another embodiment, the buyer 20 transmits a purchase request 202 to the blockchain network 250 via the transceiver module 221 and the transaction module (buyer) 242, via the transaction module (buyer) 242 in the blockchain network. 250 search for other sales or purchase needs. The content of the purchase demand 202 may include a photo, a product name, a specification, a model number, a quantity, a desired shipping method, and the like of the product to be purchased.

In one embodiment, one or more sellers 10, buyers 20 may use the keywords to search for the sales demand 201 and the purchase demand 202. After the seller 10 and the buyer 20 respectively browse the sales demand 201 and/or the purchase demand 202, when the sales demand 201 matches the purchase demand 202, the seller 10 and the buyer 20 may agree and confirm the transaction and sign the smart contract 252. The smart contract 252 is a contract between the two parties of the transaction, that is, the seller 10 and the buyer 20, and the smart contract content may include transaction materials, such as transaction goods and transaction identification codes; the two parties of the transaction are the seller 10, the buyer 20 information, such as the seller 10, the buyer 20 various voucher codes, keys, digital signatures; transaction product information, such as photos, product names, specifications, models, quantities, brief or detailed instructions, shipping methods, etc. In one embodiment, the smart contract can be built on the Ethereum platform. A smart contract is a set of commitments defined in digital form, including agreements on which contract participants can execute these commitments. A set of commitments refers to the (and often mutual) rights and obligations agreed by the contract participants. These commitments define the nature and purpose of the contract. Take a sales contract as a typical example. The seller promised to send the goods and the buyer promised to pay a reasonable payment. The digital form means that the contract has to be written into computer-readable code. This is necessary because as long as the parties reach an agreement, the rights and obligations established by the smart contract are performed by a computer or computer network. To further explain: (1) Agreement reached: When will the parties to the smart contract reach an agreement? The answer depends on the specific smart contract implementation. In general, when a participant commits to the execution of a contract by installing a contract on the contract host platform, the contract is discovered. (2) Contract execution: The true meaning of “execution” also depends on implementation. In general, implementation means active implementation through technical means. (3) Computer readable code: In addition, the specific "digital form" required by the contract relies heavily on the agreement agreed by the party. The agreement is a technical implementation, on the basis of which the contractual commitment is fulfilled, or the contractual commitment to be realized. The choice of which protocol depends on many factors, the most important factor being the nature of the assets being traded during the performance of the contract.

Referring to the description of the second figure, in an embodiment, the blockchain network 250 can authenticate the smart contract 252 corresponding to the transaction, that is, the blockchain network 250 checks the legitimacy of the transaction through the smart contract 252. It should be noted that the certification herein may include that the seller 10 and the buyer 20 agree to trade the goods in the matching sales demand 201 and the purchase demand 202, but not limited thereto. When the blockchain network 250 is successfully authenticated, the smart contract 252 and the transaction will be recorded in the blockchain.

Referring to the description of the second figure, once the seller 10 sends the traded goods by sea or air to the country where the buyer 20 is located and arrives at the customs or other customs clearance of the country where the buyer 20 is located, it is coupled to the block. After the scanner 260 of the chain network 250 scans the barcode printed on the transaction commodity, such as but not limited to the QR code and transmits it to the verification module 261, the verification module 261 verifies whether the transaction commodity belongs to the block through the blockchain network 250. A particular transaction represented by a particular smart contract stored in the chain network 250, if the transaction is successful, can be used to pay the transaction goods through the electronic payment system 251 coupled to the blockchain network 250. The account of the seller 10; conversely, if the verification fails, the transaction fails, the electronic payment system 251 does not pay the account of the seller 10, and the transaction commodity is returned to the seller. It should be noted that the above verified procedure can be performed automatically by the smart contract 252 without departing from the scope of the invention. In an embodiment, the electronic payment system 251 described above may include, but is not limited to, a Ripple open payment system.

Referring to the description of the second figure, in an embodiment, the blockchain network 250 further includes an inspection module 253, which is further delivered to the store through domestic shipping methods such as home delivery, mailing, shipping or convenience store stores. When the buyer 20 and the buyer 20 receive the purchased product, the authenticity, accuracy, and legality of the product can be checked, for example, whether the product meets the photograph, product name, specification, model, quantity, and quantity recorded in the sales demand 201. Brief or detailed instructions, etc., and whether the goods involve forgery or counterfeiting. When the buyer checks the merchandise and is satisfied with the merchandise, the inspection module 253 can confirm the completion of the transaction.

In an embodiment, when the buyer is dissatisfied with the purchased product, the product can be returned through the inspection module 253. After confirming that the goods are to be returned, the seller 10 and the buyer 20 negotiate to return the goods to be traded. After receiving the returned goods, the seller 10 completes the return procedure through the inspection module 253. In one embodiment, after the blockchain network 250 confirms that the return process is completed, the electronic payment system 251 can return the merchandise payment to the buyer 20 while the smart contract 252 will expire.

Referring to Figures 3A and 3B, the first to second figures corresponding to the above-described multi-transaction system using blockchain technology and related diagrams are shown. The following steps for the cross-border transaction method 300 using blockchain technology are described. 301 to 310 are elaborated.

A third diagram and a third diagram B illustrate a transaction flow diagram of a cross-border transaction method using blockchain techniques in accordance with an embodiment of the present invention. In this embodiment, a cross-border transaction method 300 using blockchain technology, the method includes: in step 301, a transaction module transmits a seller's sales demand to a blockchain network. Then, in step 302, a transaction module transmits a purchase request of the buyer to the blockchain network. Next, in step 303, if the sales demand matches the purchase demand and is authenticated by the blockchain network, the seller signs a smart contract with the buyer to establish a transaction. Next, in step 304, the transaction goods are sent by the seller by sea or by air. Thereafter, in step 305, when the transaction item arrives at the customs clearance of the country where the buyer is located, the scanner scans the barcode on the transaction item, such as but not limited to the QR code, and transmits it to the verification module. Next, in step 306, the verification module verifies, through the blockchain network, whether the transaction commodity belongs to a transaction represented by the smart contract stored in the blockchain network. If yes, proceed to step 307a. In step 307a, the payment for the transaction commodity is paid to the seller's account by an electronic payment system. If not, proceed to step 307b. In step 307b, the transaction fails, the electronic payment system does not pay the account of the seller, and the transaction commodity is returned to the seller. Thereafter, in step 308, the transaction item is further delivered to the buyer via a domestic shipping method such as a home delivery, mailing, shipping or convenience store. Next, in step 309a, if the buyer finds that the transaction commodity does not meet the information described in the above-mentioned sales request, the buyer can return the product through an inspection module, and the transaction commodity is returned to the seller. On the other hand, in step 309b, if the buyer finds that the transaction commodity meets the information described in the above-mentioned sales request, the transaction is completed through the inspection module. In step 310, after receiving the returned product, the seller completes the return procedure through the inspection module, and the electronic payment system returns the merchandise payment to the buyer, and the smart contract is invalid.

In summary, the multi-transaction system and method for using the blockchain of the present invention uses a blockchain network to record all transaction data, and can effectively track, query, and authenticate transactional commodities, so that the transaction process in the network It has the effect of reducing risks and improving data security.
