Crowdsourcing result evaluation and reward distribution method and system based on smart contract, and medium

Abstract

The invention provides a crowdsourcing result evaluation and reward distribution method based on an intelligent contract. The method comprises the following steps: encrypting a task solution by using a public key of a task; triggering a task evaluation and reward allocation process; the anonymous account with the answer result closest to the correct answer is selected for reward, and the reward result is recorded in the task chain module and the user chain module; obtaining current reward information of the anonymous account; initiating an application for synchronizing the reward information to the original account to the trusted execution environment module; applying for necessary user information from the user chain module so as to synchronize the information of the anonymous account to the original account; the privacy information of the original account and the privacy information of the anonymous account are combined into third privacy information of the original account, and the third privacy information is sent to the original account; a result returned by the trusted execution environment module is uploaded to the user chain module; and updating the original account. In this way, the user privacy in the reward distribution process and the fairness and justice of crowdsourcing result evaluation and reward distribution can be guaranteed.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method, system and medium for crowdsourcing result evaluation and reward distribution based on smart contracts. Background technique [0002] In recent years, crowdsourcing platforms that utilize crowd intelligence resources to handle complex tasks have received widespread attention and applications. However, most crowdsourcing platforms currently adopt a centralized architecture, which is vulnerable to destructive effects such as single point of failure, privacy leaks, distributed denial of service attacks, and Sybil attacks. At the same time, due to the opacity of the centralized crowdsourcing platform, there may be unfair problems in the evaluation of crowdsourcing results and reward distribution. In addition, since the centralized platform can only use the worker resources and task resources owned by the platform itself, it is difficult to achieve resource sharing between ...

AI Technical Summary

Problems solved by technology

In the solution of the present invention, the present invention aims at problems such as data disclosure and transparency in the existing blockchain-based crowdsourcing platform leading to user privacy leakage, opaque evaluation process in the task evaluation stage, and insufficient use of user reward information, etc., by using anonymous accounts to participate in Crowdsourcing tasks, using smart contracts on the task chain to conduct open and transparent evaluation of solutions and a trusted execution environment to synchronize reward information to the original account, to ensure user privacy in the reward distribution process, to ensure crowdsourcing result evaluation and reward distribution Fairness and justice, and better use of user reward information
