Abstract

The invention discloses a method for discounting under an export credit card item based on a blockchain, and a computer readable storage medium. According to the method for carrying out discounting under the export credit certificate item based on the block chain, the electronization of receipts is realized by utilizing a blockchain technology, the receipts are ensured not to be tampered and counterfeited, the authenticity of various receipts used in discounting business under the export credit certificate item is ensured, the transmission speed is increased, and the processing efficiency is improved. Moreover, asymmetric encryption, a Hash algorithm, a digital identity and a digital signature technology are utilized to realize true and accurate signature in a bill business process. Besides, a blockchain distributed account book technology is utilized, information islands are broken, data sharing is achieved, the problems that bank credit investigation data sources are deficient, and related information of a goods flow needs to be signed by related nodes and then uploaded to a block chain are solved, effective supervision of goods circulation conditions by nodes of all parties is facilitated, and the problem that goods circulation is not easy to monitor is solved.
