In this talk, we critically examine DePIN systems through the lens of two complementary studies. First, we provide a systematic analysis of the DePIN paradigm, identifying its core architectural pillars - blockchain, IoT, and tokenomics - and exposing fundamental vulnerabilities arising from operating in a zero-trust, open-participation environment.

In this talk, Sumayah will survey a number of malicious hosting infrastructures for different services and approaches to detecting them. Among them are works on an emerging trend of Bulletproof hosting services reselling infrastructure from lower-end service providers, use of residential proxy as a service to avoid server-side blocking and DNS based hosting infrastructure.
