Blockchain-based multi-skill mobile crowdsourcing services

Abstract With the boom in 5G technology, mobile spatial crowdsourcing has shown great dynamism industrial communications and edge computing node management. But traditional system is not advanced enough to adapt new environment. Typically, workflow hosted by a centralized platform. However, platform faces following problems: (1) single point of failure, (2) user privacy leakage, (3) subjective arbitration, (4) additional service fee, (5) non-transparent task assignment process. To improve those problems, we replaced with decentralized blockchain infrastructure. And analyzed challenge problems multi-skilled tasks system. In addition, allocation algorithm been proposed, which implements transparent distribution process can computing-constrained environment on blockchain. Compared TSWCrowd blockchain-based model, our higher rate under same conditions. experimental result shows work good economic feasibility, decentralizes significantly reduces consumption
