Abstract

One or more embodiments of the invention provide a transaction query and transaction data processing method, device and apparatus based on a block chain. The transaction query method comprises the steps that a first block chain node receives a transaction query request sent by a terminal apparatus of a core enterprise user, and the transaction query request comprises to-be-queried time and an identifier of to-be-queried transaction voucher data; according to the identifier of the transaction voucher data, corresponding target transaction record information of which the transaction time is within the to-be-queried time from the blockchain is acquired; a first smart contract is called, according to target transaction record information, a distribution diagram of accounts corresponding to the transaction voucher data is generated in the to-be-queried time, and a distribution diagram is sent to the terminal apparatus of a core enterprise user to enable the terminal apparatus of the core enterprise user to display the distribution diagram, the distribution diagram representing the distribution condition of the accounts distributed among the account holding users in the to-be-queried time.

Description

technical field [0001] This document relates to the field of blockchain technology, and in particular to a method, device and equipment for transaction query and transaction data processing based on blockchain. Background technique [0002] Supply chain finance, simply put, is a financial model in which financial institutions such as banks connect core enterprises with upstream and downstream suppliers to provide flexible financial products and services. The current supply chain financial model uses centralized financial institutions to store transaction data between core enterprises and suppliers, and there are data security issues such as data loss and data tampering, which in turn prevents core enterprises from being able to query their The accurate distribution of the accounts provided is not conducive to the core enterprises to control the status of the accounts provided. Contents of the invention [0003] The purpose of one or more embodiments of this specification ...
