Account information query method, device and system based on blockchain

Abstract

The invention discloses an account information query method, device and system based on a block chain. The system comprises a block chain network, a query bank system, a queried bank system and a payment clearing system. Wherein the query bank system initiates an account information query application to the blockchain network according to an account information query request of a user side; the queried bank system receives an account information query application pushed by the blockchain network, and returns an account information query response result to the blockchain network according to the received account information query application; the query bank system receives an account information query response result pushed by the blockchain network, and returns the account information query result to the user side according to the received account information query response result; and the payment clearing system receives and records the account information query application and the account information query response result pushed by the blockchain network. According to the invention, the parallel processing of the account query service process can be realized, the service processing efficiency is improved, and the service data cannot be tampered.
