DePIN (Decentralized Physical Infrastructure Network) is a blockchain network that connects the physical world to blockchain technology by decentralizing the control and ownership of physical infrastructure.^[1]

Overview

DePIN refers to a network of blockchain protocols that enable the development, maintenance, and operation of physical hardware infrastructure in a decentralized and open manner. These networks leverage the strengths of blockchain technology, such as immutability, transparency, and security, to facilitate the creation of peer-to-peer networks that meet hardware demands through an open marketplace.^[2]

In the traditional world, physical infrastructure like data networks, transportation, or electrical grids have been owned and managed by centralized entities. DePIN projects seek to replace this by creating peer-to-peer (P2P) networks where individuals can contribute their own physical resources and own shared control over the network.^[6]

DePIN revolutionizes the management and operation of physical infrastructure systems by employing crypto-incentives to coordinate the construction and functionality of critical infrastructure efficiently. As defined by Binance Research:

"DePIN refers to infrastructure-related projects utilizing blockchain technology and crypto economics to motivate individuals to allocate their capital or unused resources towards creating a more transparent and verifiable network, with the goal of achieving a more efficient scaling trajectory than their centralized counterpart."^[4]

The significance of DePIN lies in its radical departure from traditional, centralized approaches to infrastructure development, which have historically been dominated by large corporations due to substantial capital requirements and logistical complexities. This centralized model often resulted in a near-monopoly, stifling competition and innovation. DePIN disrupts this paradigm by decentralizing the ownership and management of infrastructure, distributing authority and proprietorship back to the users and contributors, thereby democratizing access and participation.

How Does DePIN Work?

DePIN creates a connection between physical facilities and blockchain. For a simple explanation, the major role players are a physical facility controlled by a provider, a middleware connecting the facility to the blockchain, and a public ledger that manages this connection for remittance.^[3]

• Physical infrastructure: The physical facility could be anything from a sensor, or internet router to a solar panel. This is managed by a private provider. Sometimes these providers already own these facilities before partaking in the DePIN project. As many private providers as possible can contribute their facility to a DePIN.
• Middleware: The middleware handles the bulk of the connection between the blockchain and the physical infrastructure. Like a decentralized oracle network (DON) that picks up data from the outside world and communicates it to a blockchain application. The middleware performs a similar role. The middleware gathers data on activities on each of the private facilities and relays them to the DePI Network.
• Blockchain system: Data gathered by the middleware is sent to the blockchain which serves as an administrator and a remittance system for the providers and the users. Based on data provided by the middleware, the blockchain rations demand across the providers and computes the rewards based on these activities. Rewards are sent in cryptocurrencies. On the user's end, the blockchain also handles resource procurement, where the pricing models are integrated into the remittance system and users are charged promptly for each service they utilize.

At the heart of DePIN's operational model are two fundamental crypto concepts: decentralization and the token economy. These principles, which form the bedrock of various crypto sectors, have found a unique application in DePIN, enabling an innovative and changed approach to managing physical infrastructures. By leveraging cryptocurrencies and blockchain technology, DePIN facilitates a distribution of power and ownership unprecedented in the realm of physical infrastructure management.^[4]

DePIN Flywheel

DePINs hope to grow a resource-efficient physical infrastructure through incentivization. First, providers are incentivized to commit their physical facilities to a decentralized network. In pursuit of rewards, a good number of providers, some of whom might have these facilities lying dormant, commit their facilities to the network. DePIN makes these resources available on the user side. The network generates revenue through fees paid by the users.

Users are also attracted by the cheaper service charges, relative to corporation-owned facilities. As the network grows, the native token grows in value, meaning more rewards for providers and higher attraction for investors, and even more providers. As the cycle continues and the network grows, the DePIN flywheel takes off.

Four pillars of DePIN

Here are the four pillars of decentralized physical infrastructure:

• Cloud Storage Networks/Server Networks: DePIN decentralizes storage and server networks to ensure resilient and secure data storage. Typically, centralized services have singular points of failure. However, DePIN offers a robust common storage service alternative by decentralizing data across multiple storage nodes. This includes file storage, CDN, relational database, and VPN networks.^[5] Decentralized storage networks provide users with on-demand storage space by incentivizing providers to contribute storage space. Filecoin, developed by Protocol Labs, is an ambitious decentralized storage network that aims to harness the unused storage capacity of computers around the world to create a secure, efficient, and scalable blockchain-based data storage market, seeking to decentralize the web’s storage infrastructure and present an alternative to traditional cloud storage providers like Amazon Web Services, Google Cloud, and Microsoft Azure.^[4]
• Energy Networks: DePIN’s decentralized energy network transforms energy trading and sharing. It enables directly selling or trading surplus energy within local communities and fosters a community-centric energy distribution approach. This network aggregates distributed energy sources and enhances grid resilience and efficiency.
• Sensor Networks: DePIN’s decentralized sensor networks gather precise, secure, and transparent data from various environments. This system ensures the integrity and accessibility of sensor data. It involves networked devices that are equipped with sensors to gather data in real time. It improves data integrity and mapping capability.
• Wireless Networks: DePIN redefines wireless networks, like 5G and WiFi, by creating a decentralized hotspot network. This approach democratizes internet access. It addresses the connectivity gaps often left by traditional Internet Service Providers (ISPs) in remote or rural areas. Additionally, DePIN supports technologies such as 5G and LoRaWAN (Internet of Things).

Origin and Evolution of DePINs

The seeds of DePINs were sown in the early explorations of blockchain’s potential beyond digital currencies. Projects like Power Ledger and OpenBazaar laid the foundation by demonstrating how blockchain could decentralize energy distribution and e-commerce. Power Ledger empowered individuals to trade excess energy peer-to-peer, fostering a more efficient and sustainable energy ecosystem. 

Meanwhile, OpenBazaar facilitated direct transactions between buyers and sellers, eliminating the need for intermediaries in online commerce. As the concept gained traction, new initiatives emerged, expanding the scope of DePINs across various domains. Helium, for instance, leveraged blockchain technology to create a decentralized wireless network, enabling individuals to earn rewards for providing coverage and connectivity. 

Render introduced a decentralized cloud computing platform, offering scalable and cost-effective infrastructure to developers and businesses. Unlike traditional cloud computing services, which are typically centralized and managed by a single entity (e.g., Amazon Web Services, Microsoft Azure, Google Cloud), Render’s platform decentralizes the computational resources across a network of individual providers.

Filecoin has revolutionized decentralized storage by leveraging blockchain technology to establish secure, distributed networks for data storage, where participants are incentivized through a marketplace to rent out their unused storage space.^[8]
