Decentralized Physical Infrastructure Networks (DePIN) utilize blockchain and AI to manage physical services in a decentralized manner, promoting efficiency, transparency, and sustainability across various sectors. By enabling resource sharing among participants and incentivizing contributions with tokens, DePIN seeks to transform infrastructure management and address issues like inefficiency and high costs associated with traditional centralized systems. However, the adoption of DePIN faces challenges including scalability, regulatory uncertainty, security vulnerabilities, and trust issues among stakeholders.
