Decentralized Crowdsourcing for Human Intelligence Tasks with Efficient On-Chain Cost
Summary: Decentralizes HITs via a public blockchain for payments and dispute resolution, avoiding on-chain disclosure of workers' answers. Achieves O(1) on-chain storage and O(log N) computation, uses gold standards for quality, preserves worker privacy, and provides formal security definitions and proofs.
