Embodiment Construction

[0076] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.

[0077] For ease of understanding, such as figure 1 and figure 2 As shown, the following explains the multi-party nodes involved in the blockchain network in the method of import bill remittance under the collection item based on the blockchain.

[0078] 1. Oracle node (oracle machine): The mechanism for writing information outside the blockchain into the blockchain is the only way for smart contracts to interact with the outside world, and it is also the interface for data interaction between the blockchain and the real world;

[0079] 2. Exporter node: refers to international trading companies, manufacturing companies and other units engaged in international product export;

[0080] 3. Node of the commodity inspection bureau of the exporting party: refers to t...

Abstract

The invention discloses a method for carrying out import escort under consignment items based on a blockchain, and a computer readable storage medium. According to the method, a consensus technology,asymmetric encryption, a Hash algorithm, a digital signature technology and a blockchain data structure are utilized to realize electronization, non-tampering and non-forgery of receipts, so that theauthenticity of various receipts used in business is ensured, and the problems that paper receipts are easy to counterfeit and inconvenient to verify are solved. Moreover, the blockchain network can be connected with an application layer through an interface, thereby achieving the interaction of key data, and solving a problem that the credit investigation is difficult because the operation condition and transaction history of a bank for an enterprise are not clear in a conventional trade financing business to a certain degree. Besides, all steps of the goods from sending to receiving can be recorded through the blockchain, and the whole transportation process of the goods from loading, transportation and pickup can be clearly recorded on the blockchain, so that the traceability of information is ensured, and the occurrence of packet loss and wrong claiming events is avoided.

Description

technical field [0001] The present invention relates to the technical field of import bill transfer in import and export trade, in particular, to a method for import bill transfer under collection based on blockchain, and a computer-readable storage medium. Background technique [0002] Import bill transfer refers to the business in which the bank provides short-term financing when the importer applies for foreign payment, and the applicant repays the principal and interest according to the agreed interest rate and time limit. According to the settlement method, it can be divided into import bill advance under letter of credit, import bill advance under collection and import bill advance under remittance. Import bill under collection, also known as import collection bill, is a financing advance provided by the collecting bank to the importer with the import collection documents including property documents as collateral.
