As digitalization and technological advancements continue to shape the infrastructure landscape, the emergence of blockchain-based decentralized physical infrastructure networks (DePINs) has gained prominence. However, a systematic categorization of DePIN components and their interrelationships is still missing. To address this gap, we conduct a literature review and analysis of existing frameworks and derived a taxonomy of DePIN systems from a conceptual architecture. Our taxonomy encompasses three key dimensions: distributed ledger technology, cryptoeconomic design and physicial infrastructure network. Within each dimension, we identify and define relevant components and attributes, establishing a clear hierarchical structure. Moreover, we illustrate the relationships and dependencies among the identified components, highlighting the interplay between governance models, hardware architectures, networking protocols, token mechanisms, and distributed ledger technologies. This taxonomy provides a foundation for understanding and classifying diverse DePIN networks, serving as a basis for future research and facilitating knowledge exchange, fostering collaboration and standardization within the emerging field of decentralized physical infrastructure networks.
