Reciprocal Crowdsourcing: Building Cooperative Game Worlds on Blockchain

Abstract

Crowd intelligence has become increasingly popular during recent years, thanks to the exploding global Internet usage. However, most crowd intelligence platforms ceased to operate due to the untrustworthy data or lack of motivated participants. The blockchain technologies propose decentralization as the potential solution to this dilemma. This work introduces reciprocal crowdsourcing, a novel decentralized cooperative crowdsourcing model powered by the blockchain to strengthen trust among crowd intelligence participants, who perform transparent collaborative work in the system thereafter. To validate our proposal, we implemented “Cell Evolution”, a blockchain game, in which the players can build cooperative game worlds on the blockchain with reciprocal crowdsourcing.
