In order to remove the dependence of traditional crowdsourcing on third-party central institutions, and at the same time ensure the fair distribution of crowdsourcing tasks and credible submission of results, a design scheme of trusted crowdsourcing platform based on blockchain smart contracts is proposed. First, a commitment-based two-stage submission mechanism is proposed and applied to the data submission process of recipients to solve the data transparency problem on the blockchain, so that the recipients cannot steal data from each other. Second, an unbiased random selection algorithm is designed to select relatively independent receivers from scattered receiver pools, preventing possible collusion among receivers. Finally, the randomness of the selection algorithm and the feasibility of the overall scheme are verified through selection simulation experiment and the implementation of the prototype system on Ethereum.
