Abstract

The embodiment of the invention provides a bill exchange method and device based on a block chain, equipment and a readable storage medium. The method comprises the following steps: receiving an issuing operation instruction, calling a predefined intelligent contract interface, and generating an initial document pass according to a preset document protocol in the intelligent contract interface; receiving a document pass exchange instruction, and determining an initial document pass and a target document type to be exchanged according to the document pass exchange instruction; querying an exchange in a block chain, and adding the circulation receipt pass provided by each commercial provider in the exchange to a receipt transaction pool; and according to a preset interaction protocol corresponding to the receipt transaction pool, exchanging the initial receipt pass with a target receipt pass corresponding to the target receipt type in the receipt transaction pool. According to the embodiment of the invention, the unified document pass is generated through the preset document protocol in the intelligent contract interface, and then cross-ecological-chain rapid circulation of the document pass is realized according to the preset interaction protocol.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a blockchain-based document exchange method, device, equipment and readable storage medium. Background technique [0002] At present, with the improvement of people's living standards, people are paying more and more attention to related products in the financial field, and financial products have also been vigorously developed. posed a challenge. [0003] Because the financial business is technically and professionally strong, the financial business is still operated in the traditional way offline. The offline operation of the financial business makes the information opaque, the steps are cumbersome, lack of standardization, and there is no centralized management or trading place, and the operational risk is high. The efficiency of information interaction is low and cannot adapt to the progress and development of the financial field. Some enterprises introduce bloc...
