Abstract

The invention relates to the technical field of computer internet, in particular to a blockchain-based account receivable type supply chain financing method and device, computer equipment and a storage medium. The method comprises the steps: completing the information interaction between an asset party and a fund party through a blockchain, and storing the interaction information on the blockchain; the asset side splits the information in the asset package into underlying assets and summary information corresponding to the underlying assets, and stores the summary information in the block chain; bottom layer asset files in the asset package are stored on a distributed file server; the financing application request of the asset party carries financing basic information and abstract information of an asset package and is sent to the block chain; the problem that the attached asset package is too large when the financing application request is sent is solved; the integrity of underlying asset information is ensured, and no tampering is ensured; the important interaction information of the fund party and the asset party is stored in the block chain, so that the integrity of the transaction information is ensured.

Description

technical field [0001] The present invention relates to the field of computer Internet technology, and in particular to a blockchain-based account receivable supply chain financing method, device, computer equipment and storage medium. Background technique [0002] Currently, the following working methods are adopted in the practice of accounts receivable supply chain financing: [0003] The asset party digitizes the underlying assets through the supply chain financial system, such as: scanned invoices, electronic invoices, paper contracts, electronic contracts, scanned receipts, etc., to form a digital asset package. [0004] The factorer pushes the digital asset package to the funder through the supply chain financial financing application module, and initially proposes the value of the asset package, the expected financing rate, financing period, and financing freedom. [0005] After the funder receives the financing application from the asset party: [0006] Browse fin...
