For most of internet history, the physical infrastructure that runs digital services has been controlled by a small number of companies. AWS, Google Cloud, and Microsoft Azure own the data centers. Verizon, AT&T, and T-Mobile own the spectrum. A handful of satellite operators own orbital slots.
DePIN proposes a different model: replace centralized ownership with a network of independent contributors, coordinate their behavior with blockchain-based incentives, and verify their contributions with cryptographic proofs. The infrastructure becomes community-owned without requiring a corporation to own or operate it.
That is the premise. What is actually being built, and how it works technically, is more interesting than the premise.
What DePIN Actually Is
DePIN stands for Decentralized Physical Infrastructure Networks. The category covers any blockchain protocol that incentivizes individuals or organizations to deploy, operate, and maintain physical infrastructure in exchange for token rewards.
Analysis of prominent DePIN projects reveals four recurring design primitives: verification of physical work (PoPW), where the network must prove contributors are actually providing the service they claim; fiat-denominated pricing rails, to insulate service consumers from token price volatility; token incentive distribution to hardware operators; and governance mechanisms for protocol parameters.
The key distinction from a typical blockchain protocol is that the “work” being rewarded is physical, not computational in the traditional mining sense. A Helium hotspot operator is providing wireless coverage. A Filecoin storage provider is storing actual data. An Akash node operator is running real containerized workloads. The blockchain doesn’t just record that the work happened, it verifies it.
The Two Main DePIN Categories
The sector splits into Physical Resource Networks (PRN), like Hivemapper for geospatial mapping, and Digital Resource Networks (DRN), like Render for compute. AI primarily drives demand for DRNs, where resources are fungible and location-agnostic.
| Category | What’s contributed | Example networks | Primary demand driver |
|---|---|---|---|
| Wireless connectivity | Radio coverage, bandwidth | Helium, XNET, Pollen Mobile | IoT devices, mobile data offload |
| Compute (GPU/CPU) | Processing power, inference | Akash, Render, Aethir, io.net | AI training, LLM inference |
| Storage | Disk space, retrieval | Filecoin, Arweave, Storj | Data persistence, decentralized apps |
| Sensors / geodata | Location data, telemetry | Hivemapper, WeatherXM, DIMO | Maps, autonomous systems, analytics |
| Energy | Grid balancing, generation | Energy Web, Glow | Renewable credits, demand response |
How Proof of Physical Work Operates
The fundamental challenge DePIN protocols need to solve is verification: how do you know a hardware operator is actually providing the service they claim, without trusting a centralized auditor?
Each sector uses different cryptographic and economic mechanisms:
Wireless coverage (Helium). Helium’s Proof-of-Coverage (PoC) requires hotspots to challenge and witness each other’s signals. A hotspot earns rewards only if neighboring hotspots can verify its radio signal is real and in the claimed location. Geographic spoofing is detectable because real radio physics are hard to fake at scale.
Storage (Filecoin). Filecoin uses Proof-of-Replication (PoRep), which proves a provider has stored a unique copy of client data, and Proof-of-Spacetime (PoSt), which proves they have been storing it continuously over a defined period. Both are cryptographic proofs that can be verified on-chain without trusting the storage provider’s self-report.
Compute (Akash, Render). Compute verification is harder because running an arbitrary workload produces an output, not a spatially verifiable signal. Current approaches include trusted execution environments (TEEs), redundant execution across multiple providers with output comparison, and economic slashing for providers whose outputs fail spot checks.
Technological advances in 2025 are focused on the integrated application of zero-knowledge machine learning (ZKML) and trusted execution environments (TEEs). The Ritual architecture allows nodes to choose between TEE code execution or ZK proofs based on task requirements, ensuring that every inference result is traceable, auditable, and guaranteed for integrity.
The AI Compute Angle: Why DePIN and AI Are Converging
The most significant driver of DePIN growth in 2024 and 2025 was not wireless connectivity or decentralized storage. It was GPU compute, pulled forward by demand from AI workloads.
GPU infrastructure is expected to grow from $10 billion in 2025 to $77 billion in 2035. Data center GPUs have been sold out for several consecutive months, and the decentralized computing market is projected to increase from $9 billion in 2024 to $22 billion by 2035. The structural shortage isn’t a temporary supply chain disruption, it is a consequence of AI training and inference demand outpacing the rate at which centralized data centers can be built.
That gap creates the opening for decentralized compute networks to aggregate underutilized GPU capacity from independent operators, gaming rigs, rendering farms, and edge devices, and route it to AI teams that need it.
Projects worth understanding
Render Network is a decentralized GPU rendering platform that connects GPU owners with creators and developers who need computing power for 3D graphics, motion design, visual effects, and AI model training. Providers contribute idle GPU capacity and earn RENDER tokens based on jobs they process. Render has become one of the largest DePIN projects by market cap, driven by surging demand for distributed GPU resources as AI workloads have grown.
Akash Network is a decentralized cloud computing marketplace designed for AI and data-heavy workloads, connecting enterprises and developers with idle GPU power worldwide at up to 80% lower cost than centralized providers like AWS or Google Cloud. Akash demonstrated 428% year-over-year growth in usage with utilization above 80% heading into 2026, which signals product-market fit rather than speculative capacity building.
Aethir stands out as the compute sector’s revenue leader, reporting nearly $40 million in quarterly revenue in 2025 and delivering over 1.4 billion compute hours, linking businesses and developers to more than 435,000 GPU containers across 93 countries.
Bittensor: A Different Category
While Akash and Render solve the hardware access problem, Bittensor addresses something different: the coordination of AI model outputs at the protocol level.
Bittensor is a decentralized blockchain network that creates an open marketplace for machine intelligence, where participants are incentivized with TAO tokens for producing and validating useful AI outputs across specialized subnets. Miners run AI models. Validators score their outputs. TAO emissions flow toward those producing the most valuable work, as judged by validators with economic skin in the game.
Rather than supplying hardware, Bittensor creates an incentive layer where AI models compete based on measurable intelligence output, turning machine learning into an open marketplace instead of a closed research pipeline.
The network has surpassed 128 active subnets, with the top three compute subnets reportedly achieving a combined $20 million ARR within three months of monetization. In February 2025, Bittensor transitioned to Dynamic TAO (dTAO), a market-driven system where each subnet has its own token and liquidity pool, allowing users to stake directly to the subnets they believe in.
The subnet model is what makes Bittensor relevant to builders: each subnet is essentially a specialized AI service market, from LLM inference to data scraping to prediction markets, all governed by the same underlying incentive architecture.
Regulatory Exposure: When DePIN Tokens Attract Scrutiny
DePIN token design sits in contested regulatory territory. The core question most regulators ask is whether a token represents an investment in a common enterprise with an expectation of profit from others’ efforts, which is the Howey test framework used in the US.
Tokens whose primary function is to access a service (utility tokens) are generally on firmer ground than tokens that primarily appreciate in value based on the protocol team’s efforts. The distinction matters in DePIN because many projects launch with high emission rates to bootstrap supply before demand exists, which structurally resembles a speculative investment product during the early phase.
The practical implications for builders integrating DePIN infrastructure:
- If your product consumes DePIN services (compute, storage, bandwidth), the token exposure is operational, not investment. That is generally lower regulatory risk.
- If your product issues its own token on top of a DePIN stack, that token’s design needs independent legal review.
- Cross-chain DePIN protocols that accept stablecoins for payment, rather than requiring their native token, reduce user friction and regulatory complexity simultaneously.

What DePIN Looks Like for Builders
The practical question for development teams isn’t whether DePIN is directionally correct. It is whether the infrastructure is reliable enough to build on today, and what the integration surface actually looks like.
For AI inference
Akash and Aethir offer APIs that closely mirror cloud provider interfaces. Deploying a containerized LLM inference endpoint on Akash uses SDL (Stack Definition Language), Akash’s deployment configuration format, and looks operationally similar to deploying on AWS ECS. The cost difference is real: DePIN projects like Akash and Aethir provide enterprise-grade GPUs at 60-75% lower costs than AWS or Google Cloud. The reliability SLAs are still developing compared to hyperscalers.
For storage
Filecoin and Arweave work best for large data sets with lower retrieval frequency requirements, cold or warm storage. They are not a direct substitute for S3 in latency-sensitive applications without additional caching layers.
For wireless and IoT data
Protocols like Helium’s IoT network and Hivemapper’s geospatial data layer are consumption services, not infrastructure you build on top of. They are relevant if your product consumes coverage or location data.
For custom DePIN protocol development
Building a new DePIN network, rather than consuming an existing one, is a full blockchain protocol engagement. It requires node onboarding flows, a verification mechanism for the physical work being contributed, token economic design, and the smart contracts that govern reward distribution. The concept of tokenizing infrastructure allows individuals to contribute to infrastructure development and earn tokens, ensuring that resources are more accessible and better distributed. Getting that token economic design right from the start is critical, since emission schedules and reward decay curves are extremely difficult to change after a network has contributors.
As of early 2025, the DePIN sector has 1,561 projects with a total market capitalization of approximately $30 billion, still in its early development phase. Most of those projects will not survive to operational maturity. The ones that will are those generating real demand from actual service consumers, not just recycling tokens between infrastructure providers and yield farmers.
If you are evaluating whether DePIN infrastructure fits your product’s technical requirements, or scoping a custom protocol that puts physical resources on-chain, book a call with SpaceDev’s blockchain team to assess architecture before committing to a token model.
