1st International Workshop on Decentralized Physical Infrastructure Networks (DePIN 2023)

1st International Workshop on Decentralized Physical Infrastructure Networks (DePIN 2023)

Track ID: Work-01



Decentralized physical infrastructure network (DePIN) is an emerging research area in Web3 and IoT domains, which leverage blockchain, IoT and tokenomics to incentivize communities to build physical infrastructure networks and machine economy from the ground up. DePINs are expected to disrupt existing IoT business models and enable developers to build innovative, machine-driven and decentralized IoT applications. A lot of research challenges need to be addressed to fully realize the ultimate vision of DePIN - giving back control of devices and data to users. This workshop provides a unique opportunity for researchers and industry practitioners sharing recent progress and latest work on the key aspects of DePIN and their applications.


Objectives and Motivation

Today’s IoT applications are mainly built on centralized, cloud-based infrastructures that are fully managed by organizations, with user and data lock-ins as the primary goals. The centralized ar- chitectures, while simplifying the design and deployment of IoT applications, have posed a lot of concerns regarding security, privacy, identity and data ownership. The emergence of blockchain and Web3 represents a new paradigm shift and has shed light on building innovative and decen- tralized IoT applications that are able to return control of identity and associated data back to users.

Building decentralized physical infrastructure networks (DePIN) is one of emerging areas in Web3 space which has received a lot attention from academia and industry recently. By combining blockchain, IoT and well-designed tokenomics, community-driven DePIN that are not controlled by any organization could be built. In particular, DePIN are creating new opportunities for de- velopers building machine economy applications in multiple industry sectors. Although DePIN are disrupting existing business models and have great potential for changing how IoT businesses work fundamentally, a lot of research challenges need to be addressed. The workshop aim to bring researchers and industry practitioners together to share recent progress and latest work on the theoretical and practical aspects of DePIN.



DePIN is an emerging research area in the intersection of blockchain, cryptocurrency, and IoT, and attracts increasing attention from both academia and industry. The technical innovations pre- sented in this workshop is expected to address a number of key challenges (e.g., device identity and management, off-chain computing, security and privacy, scalability, tokenomics, etc.) for deploy- ing large-scale DePIN in practice and establish a solid foundation for building the future machine economy.


Workshop Content

The workshop welcomes contributions describing design challenges, methodologies, implementa- tions, use cases, and tokenomics of building DePIN. Topics of particular interest include, but are not limited to:

  • System architectures and implementations of DePIN
  • Layer 2 solutions and cross-chain protocols for DePIN
  • Off-chain computing and blockchain oracles for DePIN
  • Experimental evaluations and performance analysis of DePIN
  • Testbeds and simulators for DePIN
  • Hardware and firmware design for DePIN
  • Device identity and management for DePIN
  • Security and privacy of DePIN
  • Disruptive and sustainable business models for DePIN
  • Tokenomics of DePIN
  • Governance protocols for DePIN
  • Use cases of DePIN in industrial and consumer environments
