Are you a DePIN? A Decision Tree to Classify Decentralized Physical Infrastructure Networks

TL;DR

This paper introduces a decision tree method to systematically classify decentralized physical infrastructure networks (DePINs) from other Web3 and Web2 systems, aiding clearer differentiation and categorization.

Contribution

The study presents a novel decision tree for classifying DePINs, based on criteria like market structure, incentives, and physical asset requirements, validated on blockchain systems.

Findings

The decision tree effectively differentiates DePIN from other systems.

Application to blockchain examples demonstrates practical utility.

Provides a foundation for a systematic DePIN database.

Abstract

Decentralized physical infrastructure networks (DePINs) are an emerging vertical within "Web3" replacing the traditional method that physical infrastructures are constructed. Yet, the boundaries between DePIN and traditional method of building crowd-sourced infrastructures such as citizen science initiatives or other Web3 verticals are not always so clear cut. In this work, we systematically analyze the differences between DePIN and other Web2 and Web3 verticals. For this, the study proposes a novel decision tree for classifying systems as DePIN. This tree is informed by prior studies and differentiates DePIN from related concepts using criteria such as the presence of a three-sided market, token-based incentives for supply, and the requirement for physical asset placement in those systems. The paper demonstrates the application of the decision tree to various blockchain systems, including Helium and Bitcoin, showcasing its practical utility in differentiating DePIN systems. This research offers significant contributions towards establishing a more objective and systematic approach to identifying and categorizing DePIN systems. It lays the groundwork for creating a comprehensive and unbiased database of DePIN systems, which will inform future research and development within this emerging sector.
