Abstract

The invention discloses an import issuing method based on a block chain and a computer readable storage medium. The invention discloses an import issuing method based on a block chain. An asymmetric encryption technology, an intelligent contract technology, a hash algorithm, a digital signature and identity authentication in a block chain are comprehensively utilized; the transaction execution process of import issuing is simplified; the possibility of default and fraud of import and export parties is reduced, the trust and risk problems in payment and delivery are solved, the trust degree ofthe two transaction parties is improved, the risk borne by a bank is reduced, the transaction safety is improved, the fund occupation is reduced, the cash flow is improved, and quicker, safer and morereliable trade activities are realized.

Description

technical field [0001] The present invention relates to the technical field of import certificate issuance in trade financing, in particular, to a method for issuing import certificates based on a block chain and a computer-readable storage medium. Background technique [0002] Such as figure 1 As shown, the import L / C is issued by the bank (issuing bank) to the foreign exporter (beneficiary) at the request and instruction of the importer (applicant), and guarantees that it will issue to the exporter (beneficiary) after receiving the documents stipulated in the letter of credit. An agreement by (the beneficiary) to pay or accept a forward payment obligation, which is a conditional bank payment commitment.
