Mobile crowdsensing (MCS) is an emerging data-driven paradigm that leverages the collective intelligence of the crowd, their mobility, and the crowd-companioned smart mobile devices embedded with powerful sensors to acquire information from the physical environment for crowd intelligence extraction and human-centric service delivery. However, existing MCS systems operate in a centralized manner, giving rise to several challenges, including privacy, security, incentives, and dependence on a central service provider. Blockchain is a novel application paradigm that incorporates point-to-point transmission, consensus mechanisms, cryptography, intelligent contracts, distributed data storage, and other computing technologies, creating a shift from the current centralized paradigm to a decentralized paradigm. Nonetheless, the convergence of MCS and blockchains necessitates addressing numerous fundamental challenges arising from their merger. This paper examines the major issues facing MCS systems and blockchain’s potential role in addressing them. We present the MCS-blockchain integrated deployment strategies, architectural designs, and core blockchain technology principles that contribute significantly to the performance of blockchain-based MCS applications. Additionally, the advancement of blockchain technology and its impact on MCS system security and performance requirements are investigated. Finally, we highlight current research gaps and future research opportunities that may inspire the deployment of novel blockchain-based MCS systems.

移动人群感知（MCS）是一种新兴的数据驱动范式，它利用人群的集体智慧、移动性以及嵌入强大传感器的人群陪伴智能移动设备，从物理环境中获取信息，以进行人群智慧提取和人类感知。以服务交付为中心。然而，现有的 MCS 系统以中心化方式运行，带来了一些挑战，包括隐私、安全、激励以及对中央服务提供商的依赖。区块链是一种集点对点传输、共识机制、密码学、智能合约、分布式数据存储于一体的新型应用范式和其他计算技术，创造了从当前集中式范式到分散式范式的转变。尽管如此，MCS 和区块链的融合需要解决合并带来的众多基本挑战。本文探讨了 MCS 系统面临的主要问题以及区块链在解决这些问题中的潜在作用。我们提出MCS-区块链集成部署策略，架构设计和核心区块链技术原理对基于区块链的 MCS 应用程序的性能做出了重大贡献。此外，还研究了区块链技术的进步及其对 MCS 系统安全性和性能要求的影响。最后，我们强调当前的研究差距和未来的研究机会，这些机会可能会激发基于区块链的新型 MCS 系统的部署。
