  This study introduces the Distributed Drone Reputation Management (DDRM)
framework, designed to fortify trust and authenticity within the Internet of
Drone Things (IoDT) ecosystem. As drones increasingly play a pivotal role
across diverse sectors, integrating crowdsourced drone services within the IoDT
has emerged as a vital avenue for democratizing access to these services. A
critical challenge, however, lies in ensuring the authenticity and reliability
of drone service reviews. Leveraging the Ethereum blockchain, DDRM addresses
this challenge by instituting a verifiable and transparent review mechanism.
The framework innovates with a dual-token system, comprising the Service Review
Authorization Token (SRAT) for facilitating review authorization and the Drone
Reputation Enhancement Token (DRET) for rewarding and recognizing drones
demonstrating consistent reliability. Comprehensive analysis within this paper
showcases DDRM's resilience against various reputation frauds and underscores
its operational effectiveness, particularly in enhancing the efficiency and
reliability of drone services.
