| Abstract: Blockchain-based crowdsourcing systems can provide users with a secure and trustworthy trading environment that does not rely on a centralized central platform. The paper systematically reviews the research work on blockchain-based crowdsourcing systems in the past five years. First of all, the concept of crowdsourcing and the basic principles of blockchain technology are introduced. Then, the problems of traditional crowdsourcing systems based on centralized central platforms and solutions based on blockchain technology are analyzed. Next, the problems in blockchain-based crowdsourcing systems and corresponding solutions have been analyzed from the perspectives of architecture design, security and privacy, consensus mechanism, and data storage. Finally, the future research directions in the field of blockchain-based crowdsourcing systems are discussed. |
