Blockchain-based Crowd-sensing System

Crowd-sensing systems have gained considerable interests and adoption in recent years. However, most existing crowd-sensing systems rely on central servers, which are subject to low reliability due to the traditional centralized architecture and high service fee. Motivated by constructing a crowd-sensing system with security and low service fee, we propose a blockchain-based crowd-sensing system (BCS), which replaces traditional triangle architecture by decentralized blockchain system. Also, in order to accelerate the formation of the fabric of trust, BCS implements applications of smart contracts to reward sensing-task workers, which offers reliable anonymity in the meantime. By leveraging blockchain technology, BCS has good performance in privacy protection and system robustness.
