Haifeng Wang's post on Goodwall - O17 Summer 2020 Challenge 4 Online crowdsourcing platform 1. Create crowdsourcing platforms for online work (e.g., design, data processing, copywriting, etc.) 2. The rewarder states the content of the job by posting the job and the timeline requirements. Set phased work assignments, number of crowdsourced collaborators, and amount of compensation. 3. The platform is equipped with restrictions such as payment collection (fraud prevention), web studio (supervisory), incomplete penalties (delay prevention), and reputation evaluation (can also be linked to flower reputation score).
