Method and device for data processing based on blockchain

TL;DR: In this paper, the authors propose a method and device for data processing based on a blockchain, which consists of a service acceptance platform node device and a service data processing party node device.

Abstract: A method and device for data processing based on a blockchain. The blockchain comprises a service acceptance platform node device and a service data processing party node device. The method comprises: the service acceptance platform node device receives service processing application data of a target user; generating, on the basis of the service processing application data, a first shared service processing result and a first private service processing result with respect to a target service data processing party; transmitting a first transaction towards the blockchain, the first transaction comprising the first shared service processing result, thus allowing the first transaction to be verified unanimously by the blockchain and then included in a distributed database of the blockchain; and transmitting the first private service processing result to the target service data processing party node device, thus allowing the target service data processing party node device to generate a second service processing result on the basis of preset service processing steps.
