报告摘要:
We design and implement the first private and anonymous decentralized crowdsourcing system ZebraLancer. It realizes the fair exchange (i.e. security against malicious workers and dishonest requesters) without any third-party arbiter. More importantly, it overcomes two fundamental challenges of decentralizing crowdsourcing, i.e. data leakage and identity breach. We also implemented our protocol for a common image annotation task and deploy it in a test net of Ethereum. The experiment results show the applicability of our protocol and highlight subtleties of tailoring the protocol to be compatible with the existing real-world open blockchain.
