【Abstract】With the gradual promotion, crowdsourcing has become an efficient way to solve problems that are very complicated for computers and simple for human crowd intelligence in recent years. Traditional crowdsourcing is based on a central system where requesters post tasks on a crowdsourcing central server or platform, however, this centralized model currently faces various challenges such as prohibitive cost, single point of failure, and vulnerability to malicious attacks. To this end, this paper proposes a smart contract-based decentralized online crowdsourcing mechanism, which includes task assignment rules and reward payment rules, etc. The mechanism has the characteristics like decentralization, unalterable, truthfulness and so on. In addition, the corresponding smart contract is designed, so that the mechanism can really run and process the actual data, and the effectiveness is shown by experiments. In this way, the entire crowdsourcing process no longer requires the participation of trusted third-party agencies, information and privacy security is guaranteed, and the cost is lower.
