Decentralized Physical Infrastructure Networks (DePIN) leverage blockchain technology to create and manage decentralized systems for physical hardware, allowing users to share resources like sensors and data storage while receiving rewards in the form of DePIN tokens. Key features include decentralization, blockchain technology for secure transactions, and smart contracts to automate agreements, all enhancing security and scalability. DePIN platforms enable peer-to-peer exchanges without traditional financial intermediaries, thereby transforming how infrastructure is developed and maintained.
