【Abstract】Blockchain is a new decentralized distributed technology, which guarantees trusted transactions in untrustworthy environments by realizing value transfer network. Because of its important value and significance to lead human society from the information transmission internet era to the value transmission internet era, it has attracted the attention of researchers in crowdsourcing services. This paper firstly observes the development trend of blockchain technology from the perspective of global government and enterprises. Then we briefly review the related concepts of blockchain and basic model of blockchain. On this basis, a comprehensive summary of the state of the blockchain research has been made on related articles which are recently published. In order to show its functional value, further investigation has been taken on the main technologies on security, privacy, and trust in crowdsourcing services and application scenarios related to this field. Finally, the advantages and challenges of blockchains are discussed. It is hoped to provide useful reference and help for the future research on blockchain technology used in crowdsourcing services.
