In a DePIN (Decentralized Physical Infrastructure Network), supply and demand are closely interconnected, creating a self-sustaining ecosystem. Supply comes from individuals or entities contributing underutilized resources like computing power, storage, bandwidth, or energy. Demand arises from users and applications needing these resources for AI, Web3, or other digital services. Token incentives balance the system by rewarding suppliers when demand grows and adjusting costs when supply exceeds usage. This dynamic pricing ensures efficiency, scalability, and fairness, while decentralization reduces reliance on centralized providers. Ultimately, DePIN aligns supply and demand through blockchain-based marketplaces, fostering innovation and global participation.
