Data processing method and device based on blockchain, terminal and storage medium

Abstract

The invention relates to a blockchain technology, and provides a data processing method based on a blockchain, which comprises the steps of creating an initial trade financing blockchain between an enterprise and a bank; receiving a data isolation request; according to the data isolation request, calling a corresponding data isolation rule to perform data isolation on the enterprise node to obtaina target trade financing blockchain; newly establishing an application store in the target trade financing blockchain, and receiving preset asset information pushed by the enterprise node through theapplication store; calling a risk control model on the bank node to screen preset asset information in the application store to obtain target asset information; and sending the target asset information to the bank node. Wherein the data and the information can be stored in the blockchain node. According to the method, the data processing efficiency of the blockchain can be improved.

Description

Technical field [0001] The present invention relates to the field of blockchain technology, and in particular to a data processing method, device, terminal and storage medium based on blockchain. Background technique [0002] In the global financial transaction market, trade financing refers to the use of structured short-term financing tools by banks in the process of commodity transactions, based on assets such as inventory, prepayments, and accounts receivable in commodity transactions (such as crude oil, metals, grains, etc.) Through trade financing, it can solve the problem of shortage of funds of enterprises, maintain the normal operation of the capital chain, and build an industrial ecology of mutual benefit and sustainable development between banks and enterprises. Blockchain networks have been increasingly used in trade finance and other financial fields due to their advantages such as distributed decentralization, no trust system, and non-tamperability.

Problems solved by technology

[0003] At present, in order to achieve the consistency of data stored in each node in the traditional blockchain-based trade financing system, it is necessary to synchronize the asset data of the transaction to each node of the blockchain network. The continuous expansion of the network occupies a large amount of storage space, which leads to a long time-consuming data synchronization of each node, thereby reducing the data processing efficiency of the blockchain and increasing the maintenance cost of the blockchain
