Generalizable DLT-based solution for DePIN Sybil resistance and quality assurance

Develop a generalizable distributed-ledger-technology-based solution for Decentralized Physical Infrastructure Networks (DePINs) that prevents Sybil attacks and guarantees quality of service, such as trustworthy sensor data, rather than relying on system-specific implementations like Filecoin’s useful-work consensus alone.

Background

Within the discussion of Distributed Ledger Technology for DePINs, the paper notes that useful-work style consensus (as in Filecoin) can, in principle, prevent Sybil attacks and guarantee quality of service, such as trustworthy data. However, the authors explicitly state that there is currently no generalizable solution for DePIN networks.

This highlights an unresolved challenge: creating a broadly applicable, DLT-based mechanism that can be implemented across diverse DePIN use cases to ensure both Sybil resistance and robust data quality assurance at scale.
