[0029] In one embodiment, if Figure 1 As shown, a cross-border transportation method based on blockchain is provided, and the method is applied to the customs node in the blockchain system, and the customs node includes the customs node of the originating country and the customs node of the target country, and includes the following steps:

[0030] S10, after the customs node of the originating country receives the cross-border transport export request sent by the seller, obtain the cargo information, price and quantity of the transported goods in the cross-border transport export request; and the buyer corresponding to the seller.

[0031] Among them, the seller is the seller who needs to carry out cross-border transportation, that is, the initiator of the transported goods; the buyer is the party that purchases the transported goods corresponding to the seller. In an embodiment of the present invention, the blockchain system includes a customs node of the originating country, a customs node of the target country, a transportation node, etc. The customs node of the originating country and the customs node of the target country correspond to individual sellers and buyers, that is, the customs node of the originating country, and the customs node of the target country can process the import and export applications of multiple sellers and buyers.

[0032] Specifically, the cargo information of the transported cargo includes all information about the transported cargo, such as the type, weight, production date, production place, and composition of the cargo, which is not specifically limited in the embodiment of the present invention.

[0033] S20, calculating the export tariff of the transported goods according to the tariff standard of the customs node of the originating country, the price of the transported goods and / or the quantity of the transported goods; and sending the export tariff collection information to the seller.

[0034] Among them, the export tariff collection information includes the cargo information of the transported goods and the export tariff of the transported goods; in an embodiment of the present invention, the export tariff collection information is sent to the seller so that the seller can determine the transported goods and the export tariff that needs to be paid, and after confirming the receipt of the export tariff of the transported goods paid by the seller, the cargo information of the transported goods and the export tariff of the transported goods are written into the blockchain system, and the transported goods are delivered to the cross-border transporter for cargo transportation.

[0035] Among them, the tariff standard of the customs node of the originating country is the tariff standard of the originating country. The tariff standard records the specific details of the tariffs required for various types of imported and exported goods. The embodiment of the present invention can levy tariffs based on the price of the transported goods as the standard, and the ad valorem tax amount = total price of the goods * ad valorem tax rate; quantitative tariffs can also be levied based on the measurement unit of the quantity of transported goods (such as "tons", "boxes", "hundreds", etc.); the transported goods can be taxed in combination with price and quantity according to various needs, and the embodiment of the present invention does not make specific limitations.
