Introduction

Research Background

Smart wearable devices, through continuous monitoring of physiological indicators and increasingly complex algorithmic analysis, are evolving from simple activity trackers to comprehensive, forward-looking personal health management tools. These devices not only significantly enhance our awareness of our own health but also seamlessly integrate into the daily lives of modern individuals through communication, mobile payments, and other functions. It can be said that smart wearable technology is fundamentally changing how people connect with the world, enjoy entertainment, and manage their health, driven by data.

The global smart wearable market is on a fast track of rapid growth. Although different market research institutions have varying predictions, they all point to a strong growth trend. For example, Grand View Research predicts that the market size will grow from approximately $84.2 billion in 2024 to $186.1 billion in 2030, with a compound annual growth rate (CAGR) of 13.6%. Mordor Intelligence is even more optimistic, forecasting that the market size will grow from about $81 billion in 2024 to $245.3 billion in 2030, with a CAGR of 19.5%. Despite differences in specific predicted figures—likely stemming from different definitions of market scope (e.g., whether certain types of hearable devices or basic wristbands are included) or different forecasting models—the overall trend of the industry approaching a hundred billion and moving towards a multi-hundred billion scale is clear, with an expected size of nearly $250 billion by 2030.

The key factors driving this growth are multifaceted. First, there is an increasing global consumer focus on health, with the concept of preventive healthcare becoming deeply ingrained, driving demand for health monitoring devices. Second, continuous advancements in sensor technology have not only improved measurement accuracy but also enabled miniaturization of devices, making smaller and more powerful wearable devices possible. Additionally, the growth of global disposable income and increased consumer spending on electronics provide an economic foundation for market expansion. At the same time, the proliferation of smartphones and Internet of Things (IoT) devices provides the infrastructure for connectivity and data interaction for wearable devices. Finally, the application scenarios for wearable technology are continually expanding, moving from the initial fitness domain to healthcare (such as remote patient monitoring and chronic disease management), fashion (such as smart jewelry), enterprise applications, and even information entertainment (such as VR/AR headsets).

In this context, DePIN (Decentralized Physical Infrastructure Networks) has emerged as a key innovative paradigm in the Web3 space. DePIN aims to leverage blockchain technology, cryptoeconomic incentives (typically achieved through the issuance of native tokens), and the collective power of communities to build, deploy, and operate physical infrastructure networks in the real world in a more open, transparent, efficient, and community-driven manner. These infrastructures can encompass various types, including sensor networks, wireless communication base stations, data storage servers, and energy networks. The core idea of DePIN is to mobilize individuals or small-scale participants to contribute their idle resources (such as hardware devices, bandwidth, computing power, and data) through token incentives, collectively building an infrastructure network that can rival or even surpass traditional centralized giants, thereby breaking monopolies, reducing costs, and allowing participants to share in the value of network development.

Chapter Two: Interpretation of the DePIN Technical Paradigm

DePIN Definition: Core Concepts and Architecture

DePIN, or Decentralized Physical Infrastructure Networks, is a rapidly emerging concept in the Web3 space, aiming to reimagine and practice the construction, deployment, and operation of real-world physical infrastructure through the application of blockchain technology, cryptoeconomic incentive mechanisms, and the power of community collaboration. This term was popularized by the crypto analytics firm Messari, although similar concepts had previously been referred to as MachineFi, Token Incentivized Physical Infrastructure Networks (TIPIN), and the Economy of Things.

The core idea of DePIN is to no longer rely on a single centralized entity (such as large corporations or government agencies) to invest massive capital in building and maintaining infrastructure. Instead, it leverages the power of decentralized networks to incentivize individuals or organizations worldwide to contribute their physical resources (such as sensors, wireless hotspots, storage servers, computing power, energy devices, and even data collected from wearable devices) to collectively build a powerful and widely covered infrastructure network.

The core elements that constitute a DePIN system typically include:

• Blockchain Technology: This is the cornerstone of DePIN. Blockchain provides a decentralized, transparent, and immutable distributed ledger for recording network status, resource contributions, service usage, and value exchanges. Smart contracts are deployed on the blockchain to automatically execute network rules, process transactions, allocate rewards, and manage access rights, enabling trustless coordination.

• Cryptoeconomic Incentives: This is the key driving force behind the DePIN model. Projects typically issue native crypto tokens to reward "supply-side" participants who provide physical resources or services to the network. These tokens serve not only as compensation but also as an incentive mechanism aimed at guiding participants to act in ways that optimize the network (e.g., deploying devices in areas that need coverage, ensuring devices are online, and providing high-quality services). Tokens can also be used to pay for network service fees, participate in network governance, or stake for additional rewards. The design of the token economic model (Tokenomics) is crucial for the success of DePIN projects.

• Community Governance: Many DePIN projects aim to achieve decentralized governance, allowing token holders or network participants to participate in the decision-making process through voting and other means. This can be realized through decentralized autonomous organizations (DAOs). Community governance aims to ensure the long-term development of the network aligns with the common interests of participants and enhances the network's resistance to censorship and its democratic nature.

• Physical Infrastructure Network: This is the core feature that distinguishes DePIN from purely digital Web3 projects. It consists of various physical hardware devices contributed by network participants, such as sensors, cameras, wireless routers, storage disks, GPU computing nodes, charging stations, and smart wearable devices, which are the focus of this report.

• Middleware/Off-chain Computing: Due to the complexity of the physical world and the performance limitations of blockchain itself, DePIN systems often require middleware or off-chain computing layers to process raw data from physical devices, validate data, aggregate information, and submit necessary results or proofs to the blockchain. For example, decentralized oracles can connect on-chain smart contracts with off-chain data sources. IoTeX's W3bstream is an example of an off-chain computing infrastructure designed specifically for DePIN.

Messari roughly categorizes DePIN projects into two types:

• Physical Resource Networks: Provide services based on hardware resources that depend on specific geographic locations. For example, deploying sensors to collect environmental data (like WeatherXM), deploying cameras or dashcams to collect mapping data (like Hivemapper), and deploying wireless hotspots to provide connectivity services (like Helium). Networks collecting health data from wearable devices also fall into this category.

• Digital Resource Networks: Provide interchangeable digital resources that do not depend on specific geographic locations. For example, decentralized storage networks (like Filecoin), decentralized computing networks (like Akash, Render, io.net), and decentralized bandwidth networks (CDNs like Meson).

From a market structure perspective, DePIN is typically described as a three-sided platform:

• Supply Side: Individuals or organizations that provide physical infrastructure resources (hardware, data, computing power, etc.), who are the primary recipients of token rewards.

• Demand Side: Individuals or businesses that consume or use services provided by the DePIN network, who typically need to pay fees (in fiat currency or tokens).

• Network/Protocol: The DePIN project itself, which establishes rules, coordinates supply and demand, distributes rewards, and maintains network operations through blockchain and smart contracts.

This structure differs from traditional two-sided markets (like Uber, which connects drivers and passengers), as the supply side and protocol maintainers in DePIN are typically different participants.

DePIN Flywheel Effect: Guiding Infrastructure

One of the most attractive concepts of DePIN is its "Flywheel Effect," which explains how DePIN effectively guides (bootstraps) the construction of large-scale physical infrastructure networks using token incentives without incurring massive upfront capital investments like traditional models.

This process typically operates as follows:

1. Token Incentives Attract Early Suppliers: At the project's launch, native tokens are distributed through airdrops, early participation rewards, and other means to incentivize the first batch of "miners" or contributors to deploy the necessary physical hardware (for example, installing a Helium hotspot or purchasing and wearing a Pulse health bracelet).

2. Network Coverage/Capacity Growth: As the number of suppliers increases, the network's infrastructure coverage expands or resource capacity increases (for example, wireless network coverage extends to more areas, storage network capacity increases, and health data networks accumulate more user data).

3. Attract Demand Side Users: The enhancement of network capabilities enables it to provide valuable services, beginning to attract end users or business clients (for example, IoT devices paying to transmit data over the Helium network, AI companies renting GPUs from the Render network for model training, and research institutions purchasing anonymous health data on HealthBlocks).

4. Generate Network Utility/Revenue, Enhance Token Value: The usage by demand-side participants generates actual network utility or direct revenue (which may be paid in fiat currency or tokens). This utility and revenue demonstrate the network's value, supporting or enhancing the market price and demand for the native token. The increase in token value attracts more suppliers: the rise in token value means that suppliers can earn higher returns by contributing resources, which incentivizes existing suppliers to continue maintaining and expanding their contributions and attracts new suppliers to join the network.

5. Positive Feedback Loop: This process creates a positive, self-reinforcing cycle—more supply leads to better services, better services attract more demand, more demand enhances token value, and higher token value incentivizes more supply.

The key advantage of the DePIN flywheel is that it distributes the enormous costs of infrastructure construction across a broad community of participants and uses tokens as an incentive tool with future value expectations to resolve the "chicken or egg" dilemma in the cold start phase. However, this flywheel is not a perpetual motion machine. Its effective operation heavily relies on a well-designed, sustainable token economic model and ultimately on whether it can successfully attract enough real demand-side participants willing to pay for services. If token incentives are set too high, leading to uncontrolled inflation, or if the network fails to generate sufficient actual utility and revenue to support token value, the flywheel may stagnate or even reverse.

Value Proposition: Why Choose DePIN to Build Physical Infrastructure?

Compared to traditional centralized models, DePIN offers a range of unique value propositions for building and operating physical infrastructure networks:

• Cost-Effectiveness: By crowdsourcing resources and reducing intermediaries, DePIN has the potential to significantly lower initial capital expenditures (CapEx) and long-term operating expenses (OpEx) for infrastructure construction. Contributors participate in the network using their existing or relatively low-cost devices, avoiding the massive construction and maintenance costs that centralized entities would incur.

• Resilience and Reliability: The decentralized nature of the network means there is no single point of failure. Even if some nodes go offline or fail, the entire network can continue to operate, thereby enhancing the overall resilience and attack resistance of the infrastructure.

• Scalability: DePIN networks can achieve organic and rapid expansion by attracting more participants to join and contribute resources to meet growing demand, without the need for large-scale, planned capacity expansion investments like centralized systems.

• Openness and Accessibility: DePIN is typically permissionless or has low barriers to entry, allowing any qualified individual or organization to participate in the construction and operation of the network, breaking the monopoly of a few giants in the traditional infrastructure sector. This not only promotes competition and innovation but also has the potential to extend infrastructure services to underdeveloped areas where costs are prohibitively high or unprofitable under traditional models.

• Transparency and Trust: Based on the characteristics of blockchain, records of resource contributions, service usage, and reward distributions within the DePIN network are publicly transparent, auditable, and difficult to tamper with, helping to build trust among participants and reduce information asymmetry and potential fraud.

• Community Ownership and Incentive Alignment: The DePIN model enables builders and users of the network (through token ownership) to become owners and governors of the network, sharing in the dividends of its growth. The token incentive mechanism aligns individual interests with the overall interests of the network, encouraging participants to contribute to the long-term healthy development of the network.

These value propositions make DePIN an extremely attractive new paradigm, especially suitable for infrastructure sectors that require extensive physical coverage, face high construction costs, or encounter issues of centralized monopolies. However, it is important to note that the degree to which DePIN's value propositions are realized largely depends on the specific project's design, execution, and ability to overcome various challenges discussed in the following chapters.

Chapter Three: The Integration of DePIN and the Smart Wearable Industry: Opportunities and Models

The New Paradigm Brought by DePIN to Smart Wearables

The combination of the DePIN technical paradigm with the smart wearable industry is expected to fundamentally change existing models, particularly bringing key transformative potential in data processing and value distribution.

Data Ownership and Value Return — Addressing "Data Silos" and Value Asymmetry:

• Current Pain Points: In the current smart wearable ecosystem, the vast amounts of health, activity, and physiological data generated by users are mostly collected and stored by device manufacturers or application platforms on their centralized servers. Users have very limited ownership and actual control over this data. Data is often locked in specific platform or brand "silos," making it difficult to migrate, integrate, or use for purposes chosen by the user. More importantly, this data has enormous potential value that can be used to drive personalized services, train AI models, conduct market research, assist in drug development, and even influence insurance pricing. However, as the producers of this data, users find it challenging to directly benefit from these derived values, resulting in significant value asymmetry.

• DePIN Solution: The DePIN model introduces blockchain technology to provide a new approach to solving this core issue. First, by leveraging the characteristics of blockchain (such as integrating decentralized identity, DID), users can theoretically achieve stronger, verifiable ownership and finer control over the data they generate (for example, managing data access permissions through private keys). Secondly, and more transformationally, the core mechanism of DePIN — the token economic incentive — can directly reward users who contribute high-quality, user-permissioned real-world data (RWD). This means users are no longer just "passive data providers," but rather become "active value co-creators and sharers," able to profit directly from the value of their data. This model is expected to break the monopoly and exploitation of data by platforms, achieving a fairer distribution of value.

Decentralized Health Data Infrastructure — Building an Open and Trustworthy Network:

• Current Pain Points: Under the current model, vast amounts of highly sensitive user health data are typically concentrated on the servers of a few large cloud service providers or device manufacturers. This centralized architecture not only brings risks of data breaches and misuse but also poses the possibility of single points of failure (service interruptions), potential censorship risks, and exacerbates interoperability barriers between different platforms and services.

• DePIN Solution: The DePIN paradigm can view millions of smart wearable devices as sensing nodes in a distributed health data network. With user consent and privacy protection, data can be stored in decentralized storage networks (such as IPFS, Filecoin, Arweave, etc.) and managed through blockchain for metadata, access permissions, and usage records. This helps build a more resilient (less prone to single-point failure), potentially more censorship-resistant, and more open data infrastructure. Furthermore, by combining advanced privacy computing technologies, such as zero-knowledge proofs (ZKP), federated learning (FL), secure multi-party computation (MPC), and homomorphic encryption (FHE), it is possible to analyze and extract value from aggregated data without exposing users' original sensitive data. This not only better protects user privacy but also provides a technical foundation for breaking data silos and promoting interoperability between different devices, platforms, and applications.

Incentive-Driven Network Effects and Deep User Engagement:

• Current Pain Points: In traditional models, after users purchase smart wearable devices, their motivation to continue wearing and using them may diminish as novelty wears off. Beyond the functionality and experience of the product itself, there is a lack of ongoing external incentives to maintain user activity and engagement.

• DePIN Solution: The token incentive mechanism provides a powerful tool to address this issue. First, token rewards can serve as a means to acquire new users, such as by offering purchase subsidies or "mining" rewards to lower the initial purchase threshold for users. More importantly, it can incentivize users to continuously wear devices and contribute high-quality, real-world health data. The "Wear-to-Earn" or further "Live-Healthy-to-Earn" models can link users' daily health behaviors (such as reaching step goals, ensuring sleep quality, completing exercise tasks) to direct economic rewards (token rewards). This is crucial for AI health model training and large-scale health research projects that require vast amounts of real, continuous data. This model is expected to attract user groups interested in both Web3 technology and healthy lifestyles, significantly enhancing user stickiness and engagement depth, potentially forming a strong positive feedback loop: "More active users -> Contribute more high-quality data -> Train better AI models and health services -> Attract more new users." Additionally, through governance via DAOs (Decentralized Autonomous Organizations), DePIN projects can allow users to directly participate in network development strategies, protocol upgrade decisions, data usage rules, and value distribution mechanism design, thereby establishing a stronger sense of community belonging and ownership.

Empowering AI-Driven Personalized Health and Precision Medicine:

• Current Pain Points: The potential of artificial intelligence in the health field is enormous, but the effectiveness of its models highly depends on large-scale, high-quality, diverse, and longitudinal real-world data (RWD). However, currently, acquiring such data is costly, and the data is scattered across various disconnected "data silos," severely limiting the development of AI health applications.

• DePIN Solution: DePIN, through its inherent economic incentive mechanism, has the potential to aggregate larger-scale, more diverse (from different populations, device types, and geographical locations), and longer-duration (because incentives are ongoing) real-world health data (RWD) than ever before. This high-quality, high-density RWD serves as valuable "fuel" for training and optimizing the next generation of AI health algorithms. When these data are combined with powerful AI analytical capabilities, they can drive more precise personalized health risk assessments, early warning signal detection for diseases, customized lifestyle intervention recommendations, and real-time tracking of drug treatment effects. Furthermore, this model even has the potential to support decentralized clinical trials (DCTs) by incentivizing participants to use wearable devices to collect trial data at home or local clinics, thereby reducing trial costs, expanding participant recruitment, and improving data collection frequency and authenticity.

This shift from a product-centric to a network-centric value proposition represents a fundamental change brought by DePIN.

In traditional models, users purchase a product and its accompanying services, with value primarily reflected in the device's functionality and the analysis reports provided by the platform. In the DePIN model, the device purchased by users also serves as a "ticket" or "production tool" for participating in a value network. Users contribute data or resources to the construction and operation of the network, which generates collective value (such as large-scale datasets and network service capabilities) from these contributions and distributes this value to participants in the form of tokens. Therefore, the role of users evolves from being mere "product consumers" to "network participants, contributors, and even co-owners," with the source of value expanding from a single product to the activities and outputs of the entire network.

Exploration of Integration Models

The integration of DePIN and smart wearables can take various forms, with existing products making attempts in these directions:

Hardware-as-a-Node

This is the most basic and direct integration model. Users' smart wearable devices — whether smartwatches, bands, rings, smart clothing, or medical patches — themselves constitute the physical sensing nodes of the DePIN network. These devices are responsible for collecting users' physiological data (heart rate, body temperature, blood oxygen, etc.), activity data (steps, types of exercise, intensity), sleep data, and even environmental data (such as location, noise levels — referencing the Silencio project). The collected data may undergo preliminary processing and analysis on the device (at the edge), and then, with the user's explicit permission, contribute the (possibly anonymized or privacy-processed) data to the DePIN network in exchange for corresponding token rewards.

"X-to-Earn" Economic Model Design

Core Idea: The core of this model is to directly link users' specific behaviors or states with token rewards to incentivize user participation and contribution. Here, "X" can represent various meanings, such as:

• Wear-to-Earn: Simply wearing the device continuously and staying online.

• Move-to-Earn / Exercise-to-Earn: Rewards based on users' steps, exercise duration, intensity, or achieved exercise goals (similar to the concept of Stepn, but applied to a broader range of health metrics).

• Sleep-to-Earn: Rewards based on users' sleep duration, sleep quality scores, HRV recovery status, etc.

• Share-Data-to-Earn: Rewards for users choosing to share (privacy-processed) data with research institutions or other third parties.

• Live-Healthy-to-Earn: A more comprehensive concept that rewards users for achieving overall health goals or maintaining healthy lifestyle habits.

Designing a token economic model that is sustainable in the long term, effectively incentivizes, and can withstand the risk of economic collapse is key to the success of DePIN x wearable projects and one of the biggest challenges.

• Token Issuance Mechanism: What is the total supply? What is the release rate? Are there halving cycles or other inflation control mechanisms? It is necessary to avoid rapid token releases that could lead to excessive early "sell pressure."

• Reward Distribution Rules: What dimensions are rewards based on? (For example, wearing duration, data completeness, data quality metrics such as sleep scores/HRV/exercise intensity, achievement of health behaviors, data sharing permissions, etc.). How is the authenticity and validity of contributions verified? (An effective Proof of Physical Work mechanism is needed to prevent cheating). Should rewards be dynamically adjusted to adapt to the network's development stage and user behavior?

• Preventing Cheating and Sybil Attacks: How can we effectively prevent users from improperly obtaining large rewards through simulated data, wearing multiple devices (witch attacks/Sybil attacks), etc.? This may require a combination of device authentication (such as Peaq ID), biometric recognition, behavioral pattern analysis, social graph verification, or trusted hardware.

• Token Consumption Scenarios/Empowerment: Beyond trading on secondary markets, tokens must have real uses and consumption scenarios within the ecosystem to create endogenous demand and support their value. For example, they can be used to purchase premium membership services, unlock more in-depth health analysis reports, pay for personalized AI coaching fees, participate in platform governance voting, stake for higher rewards or network profit sharing, and redeem health products or services at ecosystem partners.

• Value Capture Mechanism: How can external revenues generated by the DePIN network (for example, fees paid by B-end institutions for using aggregated data or analytical services) effectively flow back into the token ecosystem to support the long-term value of the token? Common mechanisms include using protocol revenue to buy back and burn tokens (deflationary model) or distributing revenue to token stakers, etc.

Data Value Capture and Application Closed Loop

The health RWD aggregated by the DePIN network, with user permission and privacy processing, has potential commercial value for B-end institutions across multiple industries. For example:

• Research Institutions (Academia, Pharmaceutical Companies): Used for epidemiological research, drug development (such as real-world evidence RWE), clinical trial participant recruitment, and data collection.

• Insurance Companies: Used to improve actuarial models, conduct more precise risk assessments, and design personalized health management plans and premiums.

• AI Companies: Used to train and optimize health-related AI models.

• Employers: Used to support employee health programs and enhance overall well-being. Clearly identifying these potential demand sides and establishing effective cooperation models is key to the commercial sustainability of DePIN projects. Projects like Synapx and Brainstem explicitly aim to connect data suppliers (users) with data demanders (research/medical institutions).

Due to the extreme sensitivity of health data, any data sharing and value exchange must be predicated on robust privacy protection technologies. Technologies such as federated learning, secure multi-party computation (MPC), zero-knowledge proofs (ZKP), differential privacy, trusted execution environments (TEE), or homomorphic encryption (FHE) must be employed. The goal is to achieve aggregated analysis, model training, and value sharing of data without exposing individual raw data, while strictly adhering to data privacy regulations such as GDPR and HIPAA.

An ideal DePIN x wearable ecosystem should form a sustainable value cycle: Data demanders (B-end) pay fees (which can be fiat currency or project tokens) to obtain data insights or use data-based services -> These fees are automatically distributed to data contributors (users), potential node operators, protocol developers, or DAO treasuries through smart contracts in the DePIN network, according to preset agreements -> Token rewards incentivize more users to join the network, continuously wear devices, and contribute high-quality data -> Larger-scale, higher-quality data attracts more B-end demanders and may increase the pricing of data services -> Increased revenue further supports token value and reward distribution, forming a positive cycle.

Integration with RWA (Real World Assets)

• Data Assetization: This is a more cutting-edge exploration direction aimed at transforming personal health datasets (or their access and usage rights) that have clear value, are strictly permitted by users, and have undergone privacy processing, into a "data asset" that can be verified on-chain, managed, and even traded under compliance conditions through specific blockchain protocols (possibly combined with NFT or DID technology). DePIN is considered a subset or related field of RWA. This assetization makes the ownership, usage rights, and value flow of data clearer, programmable, and transparent.

• Innovative Financial Applications: Based on these verified and authenticated trusted data assets, innovative financial applications may be explored in the future. For example:

• Providing individuals with more precise health risk assessments based on their health data verification, thus achieving highly personalized insurance product pricing and underwriting.

• Exploring some form of securitization of users' future "data revenue rights" (i.e., expected token rewards from sharing data) or using them as collateral for lending in decentralized finance (DeFi) protocols (though this faces significant compliance and technical challenges).

• Creating prediction markets or health index derivatives based on collective health data performance.

Important Note: Health data RWA is still in a very early and highly experimental stage. It faces significant challenges in terms of technological maturity (how to securely and compliantly package and trade data), regulatory compliance (involving complex regulations related to data privacy laws, financial securities laws, etc.), market acceptance, and ethical considerations. Therefore, it is essential to assess its feasibility and potential risks with extreme caution.

Integration of AI and Edge Computing

• Edge Intelligence: Deploying lightweight AI models on the smart wearable device side (i.e., edge side) can enable real-time health status analysis, anomaly pattern detection, activity type recognition, and other computations directly on the device. The benefits of this approach include: providing instant feedback to users; reducing reliance on cloud servers for computation, thereby lowering network transmission load and latency; and significantly enhancing user privacy protection since sensitive data is processed locally.

• Cloud Intelligence: The global, large-scale data aggregated by the DePIN network (of course, this data must undergo strict privacy protection processing, such as aggregation, anonymization, or using privacy computing technologies) can be used in the cloud to train more complex and powerful AI models. These models can discover deeper collective health patterns, disease risk factors, and potential interventions.

• Cloud-Edge Collaboration: Edge intelligence and cloud intelligence can work together. The edge side is responsible for real-time processing, preliminary analysis, and personalized feedback, while the cloud side is responsible for deep training of models, global insights, and knowledge updates, and sends optimized models or rules back to edge devices, forming a dynamically optimized intelligent system.

• Physical Perception AI: Combining multimodal data collected by smart wearable devices (including biological signals, motion data, environmental data, and even users' voice commands or interaction information) with advanced AI models can achieve smarter human-computer interaction, more precise situational awareness (e.g., recognizing users' current states and needs), and more adaptive personalized services (e.g., automatically adjusting reminders or suggestions based on users' stress levels). The AI coaching functions mentioned in projects like CUDIS and WELL3 reflect this direction.

Potential for Integration of Different Wearable Device Forms with DePIN

Smartwatches/Bands

• Advantages: The user base is the largest, with high market penetration; relatively rich functionality, usually equipped with displays and various sensors (motion, heart rate, sleep, GPS, etc.), providing multidimensional data; certain interactive capabilities, making it easy for users to set up and view information. They are an important entry point for the DePIN network to acquire users and diverse data.

• Challenges: Balancing the increase of DePIN-related tasks (such as continuous connectivity, data encrypted uploads, and possible on-chain interactions) with maintaining acceptable battery life for users is a key technical challenge.

Smart Rings

• Advantages: The biggest feature is the unobtrusive wear, leading to high user compliance, especially suitable for continuous 24/7 monitoring, particularly for high-quality collection of nighttime sleep data (such as temperature, HRV, sleep stages). This perfectly aligns with the DePIN network's demand for continuous, passive, high-quality data streams. Additionally, the ring form is also suitable for integrating payment, identity authentication, and other functions, which can be combined with DePIN's value exchange or identity verification mechanisms.

• Disadvantages: Interactive capabilities are very limited (usually no screen), functionality is relatively singular, mainly focused on health tracking; battery capacity is smaller compared to watches, making power management extremely demanding.

Smart Clothing/Patches

• Advantages: Being closer to the body, the sensor positions are more stable, potentially allowing for more accurate physiological signals than wrist-worn devices, such as multi-lead electrocardiograms (ECG), electromyography (EMG), respiratory rates, etc. Therefore, they are particularly suitable for applications requiring high-precision data in medical-grade monitoring scenarios or professional sports training analysis. They can play a key role in specific vertical DePIN networks, such as data collection networks for decentralized clinical trials (DCT) or management networks for specific chronic diseases (e.g., cardiovascular diseases).

• Challenges: Comfort of wear, durability (e.g., performance after multiple washes), cost, and user acceptance are major obstacles.

Hearable Devices/VR/AR

• Advantages: They can integrate biological signals (such as some headphones exploring heart rate monitoring, and VR/AR headsets potentially integrating EEG monitoring) with users' environmental sound information, interaction behavior data, visual attention data, etc., providing unique multimodal data dimensions for DePIN applications in scenarios such as the metaverse, immersive health experiences (e.g., meditation guidance, virtual rehabilitation training), and professional skills training.

• Challenges: Power consumption issues are more pronounced; wearing duration is usually limited (especially for VR/AR); user acceptance and the popularity of application scenarios still need improvement.

Different forms of wearable devices exhibit significant differences in physical characteristics, sensor capabilities, battery life, wearing methods, and user interaction modes. These differences determine their respective advantages and disadvantages in collecting specific types of data. For example, rings are particularly suitable for accurately measuring temperature and nighttime HRV due to their stable placement on the finger, while patches are better at capturing multi-lead ECG signals. Since the DePIN network typically requires continuous and reliable data input to maintain its value and functionality, it is foreseeable that optimized DePIN networks targeting specific data types or application scenarios may emerge in the future, with the main data contributors likely concentrated on the device forms best suited for those scenarios. For instance, a DePIN network focused on high-precision sleep analysis may primarily consist of smart ring users, while a DePIN network serving remote heart disease monitoring may rely more on smart patches or watches with medical-grade ECG capabilities.

This specialization of data collection based on device form may be an important direction for the future development of DePIN x wearables.

Chapter 4: Market Landscape and Case Analysis

This chapter aims to analyze representative projects at the intersection of DePIN and smart wearables, examine the competitive landscape, and delve into the early explorations and challenges faced by DePIN applications, using the rapidly developing smart ring market as an example.

DePIN x Smart Wearable Projects

Currently, projects that explicitly combine the DePIN concept with smart wearable hardware are still in the early stages, but there are some noteworthy explorers.

CUDIS Ring (Solana Ecosystem):

• Positioning and Product Logic: CUDIS positions itself as the first blockchain-driven DePIN smart ring, aiming to promote healthy lifestyles through gamification and community incentives ($CUDIS token). Users wear the ring to track health metrics (heart rate, blood oxygen, sleep, activity) and earn tokens by completing health tasks and sharing data (with user authorization). The core idea is that users own and can selectively monetize their health data, building a user co-created health data ecosystem.

• Economic Model: The native token $CUDIS has a total supply of 1 billion. Distribution includes user mining rewards (50%), community and ecosystem development (held by the foundation), and team and early investors (with lock-up periods). Users earn $CUDIS through daily activities, health challenges, and community contributions. Tokens can be used to purchase services within the platform and participate in governance voting.

• Market Performance and Feedback: CUDIS claims to have achieved over $4 million in ring sales, selling more than 15,000 rings and having over 100,000 community members. The project completed a $5 million funding round in September 2024. However, public user feedback is polarized. Some users appreciate its concept and potential benefits, while others express concerns about the long-term value and sustainability of its token. More importantly, some users reported serious accuracy issues, particularly with step counts and sleep monitoring data being "severely inaccurate," leading to a lack of trust in the measurement results.

HealthBlocks (IoTeX Ecosystem):

• Positioning and Model: HealthBlocks is a decentralized health data platform built on the IoTeX blockchain, aiming to connect various health monitoring devices (not limited to specific brands or forms, including watches, bands, etc.), allowing users to securely store, manage, and (with authorization) share their health data and earn token rewards. It focuses more on building a universal, interoperable health data infrastructure layer rather than selling proprietary hardware.

• Project Progress and Scale: HealthBlocks is one of the more well-known DePIN projects within the IoTeX ecosystem. IoTeX, as an L1 platform focused on DePIN, experienced significant growth in 2024, with a substantial increase in transaction volume, active accounts, and the number of projects built. The IoTeX ecosystem has over 250 projects, more than 50 of which are DePIN projects. However, there is currently a lack of publicly available data on HealthBlocks' specific user scale, activity, or the number of connected devices, with most information describing the overall IoTeX ecosystem.

Pulse (Solana Ecosystem):

• Positioning and Model: Pulse positions itself as an advanced health tracking wearable DePIN project based on Solana, emphasizing medical-grade biometric data collection, user data ownership, AI-driven personalized health insights (sleep, longevity, nutrition), and incentivizing healthy behaviors through cryptoeconomic rewards. Its goal is to build a "digital twin" of the user on-chain.

• Products and Technology: It offers its own branded Pulse wearable devices, claiming to continuously monitor heart rate, HRV, sleep stages, blood oxygen, temperature, stress, exercise, and metabolic indicators. It utilizes Solana for decentralized data storage and provides personalized recommendations through an AI engine while emphasizing user control over data and privacy protection.

• Project Progress and Scale: After its launch, the first five batches of pre-sale devices sold out quickly, indicating some market interest. It completed a $1.8 million pre-seed funding round by the end of 2024 and raised an additional $500,000 on crypto fundraising platforms Echo and Legion. In collaboration with the DeSci (Decentralized Science) platform pump.science, it launched the first study on the efficacy of supplements conducted on-chain using wearable devices, with participants wearing Pulse devices to collect data. This indicates that Pulse is actively exploring the application value of its data in health research.

WatchX Network (IoTeX Ecosystem):

• Positioning and Model: WatchX positions itself as an AI DePIN ecosystem based on smartwatches, supported by the IoTeX Foundation and others. Its smartwatches integrate multi-chain wallets, AI health finance (HealthFi), and dApps, serving as management hubs and DePIN nodes. Users earn points by completing health activities (running, cycling, uploading health data), which can be redeemed for benefits, NFT gear, or crypto assets. It introduces elements of a "metahuman" nurturing game. It emphasizes biometric recognition, self-custody privacy, and large-scale adoption of Web3.

• Products and Technology: It offers several smartwatch hardware options, such as the high-end "Pioneer" version (titanium alloy, sapphire glass, solar charging, long battery life) and the mass-market "Fusion" version (AMOLED screen, GPS, microphone/speaker). The watches run on WatchX OS, featuring standard health monitoring functions (heart rate, blood oxygen, sleep, activity tracking), supporting Bluetooth connectivity and IP68 waterproofing. They include a non-custodial crypto wallet and use NFTs as users' on-chain identity credentials. The accompanying WatchX mobile app is available on platforms like iOS.

• Project Progress and Scale: The project has an active GitHub repository, indicating ongoing development work. Its app has been launched in app stores, and hardware products (such as the Fusion watch) are available for purchase through retail channels (like HeliumMart). However, specific data on the actual number of users, community size, or market traction remains unclear.

The diversity of these projects reflects that the combination of DePIN and smart wearables is still in a very early exploratory stage.

They differ in hardware strategies (in-house development vs. connecting third-party devices), incentive models (gamification vs. direct rewards), technology platforms (Solana vs. IoTeX), and target users (general public vs. vertical fields). While some projects have shown initial market interest and fundraising capabilities, they generally face challenges related to accuracy, practicality, and the sustainability of their economic models as pointed out in user feedback. No project has yet proven successful in crossing the chasm to achieve large-scale, sustainable operations.

Potential Strategies of Traditional Giants

In the face of the emerging DePIN paradigm, traditional smart wearable giants (Apple, Samsung, Google) are unlikely to quickly and thoroughly embrace a fully decentralized model, as this fundamentally conflicts with their existing, highly successful centralized business models and data strategies. Their potential strategies may evolve in phases.

Short-term (1–2 years):

• Watch and Research: Closely monitor developments in the DePIN field, especially projects related to health data and user incentives. Assess their technical feasibility, market acceptance, and potential threats or opportunities for existing businesses.

• Strengthen Own Platforms: Continue to enhance their centralized health platforms (such as Apple Health, Samsung Health, Google Health Connect/Fitbit) by providing more refined data analysis, personalized recommendations, and a richer application ecosystem to increase user stickiness and solidify their competitive moat.

• Limited Blockchain Exploration: They may explore blockchain applications in specific scenarios without touching their core business model, such as improving the security and verifiability of health records, but this is likely to occur within their controlled consortium chains or private frameworks.

Mid-term (2–4 years):

• Strategic Investments or Acquisitions: If certain DePIN x wearable startups demonstrate significant technological breakthroughs or market potential, giants may quickly acquire relevant technologies, talent, and user bases through investments or acquisitions, integrating (or transforming) them into their ecosystems.

• Launch "DePIN-like" Incentive Programs: They may introduce centralized control user incentive programs similar to DePIN, rewarding users for sharing more health data or achieving health goals through points, membership benefits, service discounts, or other non-cryptocurrency means. This approach can borrow from DePIN's user participation concept without introducing tokens and the complexities of decentralized governance. Samsung's Samsung Rewards or similar programs could be expanded into the health domain.

• Limited API Opening: They may open some processed or aggregated health data APIs to trusted third parties (possibly including certain DePIN projects) under strict control to expand their platform ecosystem, but it is unlikely they will open raw data or allow users to fully control data flows.

Long-term (5 years and beyond):

• Lead or Build Networks (if DePIN proves disruptive): If the DePIN model is widely validated by the market and poses a substantial threat to the existing landscape, it is possible that giants will leverage their vast resources (user base, hardware entry points, funding, brand) to build or lead related "permissioned" or "consortium" decentralized health data networks and standards. However, this would require overcoming their deeply ingrained centralized tendencies and obsession with absolute data control, representing a profound strategic transformation.

• Ecosystem Integration: Deeply integrate DePIN (or its variants) capabilities into their operating systems, cloud services, and hardware products to provide a seamless user experience, but it is likely they will still maintain core control over their ecosystems.

Major Challenges for Giants Integrating DePIN:

• Business Model Inertia: Relying on hardware sales profits and increasingly important subscription service revenues conflicts with DePIN's value proposition of returning data ownership to users.

• Data Control: Giants view user data as a core strategic asset used to improve products, personalize services, and (for Google) advertising. Giving up complete control over data and allowing users to decide data flow and monetization contradicts their core interests.

• Regulatory and Compliance Complexity: Operating globally requires navigating extremely complex privacy regulations (GDPR, HIPAA, PIPL, etc.). Mapping these regulatory requirements to decentralized networks that may involve tokens presents significant compliance challenges and risks.

• Brand Image and Risk: The volatility of the cryptocurrency market, potential fraud risks, and the immaturity of early DePIN projects may cause giants, who prioritize brand image and stability, to hesitate in deep participation.

Although Samsung has launched the Samsung Blockchain platform to support DApps and hardware wallet connections, this is more about embracing Web3 infrastructure, and there are no clear signs of adopting the DePIN model in the health data field. Apple and Google mention decentralization or DePIN strategies even less in public information, seeming more inclined to enhance their health data platforms using technologies like AI within existing frameworks.

Overall, the likelihood of traditional giants embracing open DePIN on a large scale in the short term is low; they are more likely to adopt a cautious observation, limited experimentation, or strategic integration approach.

Case Study: Smart Ring Market

Smart rings, as an emerging and highly regarded form of smart wearables, provide a unique wearing experience and data collection characteristics, making them an interesting window to observe the potential of DePIN applications.

The core appeal of smart rings lies in their understated fashion, comfortable wear, and suitability for all-day (especially during sleep) unobtrusive monitoring. Compared to smartwatches, their functions typically focus more on core health metrics (sleep, heart rate, temperature, activity), with very limited or no interactive interface. The global smart ring market is experiencing rapid growth, with projections indicating that the market size will exceed $2.5 billion by 2032, with a compound annual growth rate approaching 30%.

Oura Ring

• Technology and Functionality: Oura is the leader and benchmark in the smart ring market. Its core selling point is precise sleep analysis, utilizing PPG sensors to monitor heart rate and HRV, NTC temperature sensors to track temperature changes, combined with an accelerometer for activity and sleep tracking. The product emphasizes design (titanium alloy material) and fashion (collaboration with Gucci). By partnering with professional sports leagues like the NBA and health platforms like Dexcom (blood glucose monitoring), Natural Cycles (fertility tracking), and Strava (exercise recording), it continuously expands its application scenarios and professional recognition.

• Business Model: It adopts a hardware sales model (approximately $300–400) + mandatory monthly subscription ($5.99/month). The subscription fee unlocks the full app features, personalized insights, and ongoing algorithm updates. This model emphasizes the continuous value of software and services.

The integration of DePIN and smart wearables is still in its infancy, with diverse projects like CUDIS, Pulse, and WatchX emerging, but all face challenges related to technological maturity, market validation, and the sustainability of their economic models.

Traditional giants are cautious about DePIN and are unlikely to disrupt their own models in the short term. The smart ring market, due to its characteristics, has become an early testing ground for DePIN applications, with Oura's success and Samsung's entry intensifying competition and setting high user experience and value benchmarks for DePIN ring projects.

For DePIN to establish itself in this field, it must provide unique value that surpasses existing products (such as data ownership and meaningful incentives) and effectively address fundamental technical and economic challenges.

Chapter 5: Challenges, Risks, and Future Outlook

The integration of DePIN and smart wearables paints an exciting picture, but it still faces multiple severe challenges and risks on the path to large-scale application and realizing its full potential. Of course, future development trends also indicate new opportunities.

Challenges and Risks Faced

Data Quality and Standards

• Data Quality: While the accuracy of consumer-grade smart wearable device sensors is continuously improving, there remains a gap compared to medical-grade devices, and they are susceptible to various interferences. For DePIN networks, aggregating sensor data from different brands, models, wearers, and environments makes it difficult to ensure accuracy and consistency. This "input-side" data quality issue directly impacts the overall reliability and usability of the data in the DePIN network, subsequently affecting the credibility of AI training, health assessments, or value exchanges based on this data.

For example, heart rate monitoring based on photoplethysmography (PPG) performs reasonably well under static conditions (some studies have found that the error is within ±3% in controlled environments), but during physical activity, especially in uncontrolled outdoor environments, the influence of motion artifacts can significantly increase the error. Research indicates that the accuracy of PPG sensors may also be affected by the wearing position (accuracy at the wrist is generally lower than at the forehead or chest), the fit of the device to the skin, and even the user's skin color (some studies suggest that darker skin tones may reduce PPG signal quality or accuracy, although conclusions are not entirely consistent).

• Interoperability Standards: The current smart wearable device market still lacks unified data formats, API interfaces, and communication protocols. Data across different brands and ecosystems often cannot interoperate. This poses a significant barrier to building a DePIN network that can aggregate data from diverse devices. Users may own devices from multiple brands, and if the data from these devices cannot be integrated and utilized within the same DePIN network, it will greatly diminish the network's value and user experience. Establishing industry-recognized data standards and open interoperability protocols is a key prerequisite for realizing the potential of DePIN networks.

Data Transmission and Trusted Storage

• Off-chain and On-chain Synchronization Efficiency and Trustworthiness: The core of the DePIN network lies in mapping the workload or data contributions from the off-chain physical world to the on-chain environment in a verifiable manner to trigger incentives or state updates. Therefore, off-chain storage solutions (such as distributed storage systems like IPFS, Arweave, or centralized servers) need to balance cost, credibility, integrity, and access management issues. More importantly, it is essential to ensure consistency between off-chain data processing and on-chain states to prevent data inconsistencies or double-spending issues caused by network delays, node failures, or malicious actions (especially when it involves payments or asset transfers). Middleware/L2 solutions like IoTeX's W3bstream attempt to address some of these issues by aggregating off-chain data to generate verifiable proofs on-chain, but this also introduces new complexities and trust assumptions. Data retrieval speed is also a potential bottleneck.

• Power Consumption Experience: Throughout the entire process from hardware to network, from off-chain to on-chain, how to ensure participation in the DePIN network while maximizing device battery life and avoiding user anxiety about battery life is a critical technical challenge that DePIN x wearable projects must solve, as well as a fundamental user experience issue. This is especially true for smart wearable devices with limited battery capacity due to size constraints (especially small devices like rings and earbuds), where continuous network connectivity and data processing pose significant power consumption challenges.

Economic Model Sustainability

• Token Value Support: The core of DePIN projects is their token economic model. A key challenge is how to ensure that the issued tokens have real, sustainable intrinsic value, rather than relying solely on market speculation or Ponzi mechanisms. The value of the tokens ultimately needs to be supported by the actual utility or revenue generated by the network. This requires project teams to find reliable value capture mechanisms:

• External Ecosystem Drivers: For example, selling the data collected by the entire network or the services provided (such as computing power, bandwidth) to enterprise clients (research institutions, insurance companies, AI companies, etc.) and using a portion of the generated revenue to repurchase and destroy tokens or distribute dividends to token holders, thereby endowing the tokens with intrinsic value.

• Internal Ecosystem Consumption: Designing effective token consumption scenarios, such as users paying service fees, developers deploying applications, node staking requirements, governance voting, etc., to balance the issuance and circulation of tokens. A lack of real external demand and effective value capture can easily lead to a death spiral for models that rely solely on internal circulation and new user input in an "X-to-Earn" model. In 2024, DePIN projects began to view revenue as a core operational and valuation metric, reflecting the market's increasing emphasis on sustainability.

Regulation and Compliance

• Data Privacy Regulations: Personal health data is subject to strict legal protections worldwide, such as the EU's General Data Protection Regulation (GDPR), the U.S. Health Insurance Portability and Accountability Act (HIPAA), and China's Personal Information Protection Law (PIPL). These regulations detail the collection, processing, storage, use, cross-border transfer of data, and user rights (such as access, correction, and deletion). Due to its decentralized nature, DePIN projects face unique challenges in meeting these regionally specific and detailed regulatory requirements: How to clarify the responsibilities of data controllers and processors in a distributed network? How to effectively respond to users' privacy requests? How to ensure compliance with cross-border data flows? How to conduct security audits and risk assessments? Recent updates to HIPAA have further strengthened requirements for patient record access, reproductive health data privacy, and substance use disorder (SUD) record processing, increasing compliance complexity. DePIN projects must invest significant resources in legal consulting and technical design to ensure their operations comply with privacy regulations in all relevant jurisdictions. Concerns about privacy breaches are also a significant barrier to adopting DePIN.

• Legal Classification of Tokens: The legal nature of native tokens issued by DePIN projects is uncertain in different countries/regions. Regulatory bodies, such as the U.S. Securities and Exchange Commission (SEC), may classify certain tokens as "securities," thereby requiring project teams to comply with complex securities issuance registration, information disclosure, and trading rules. Overall, regulatory exploration and gradual improvement have been ongoing in various countries/regions over the years. From a long-term development perspective, it is essential to maintain attention to regulation; of course, this regulatory uncertainty also brings legal risks and compliance costs to DePIN projects.

• Medical Device Certification: If the functions provided by DePIN projects and their associated smart wearable devices exceed the scope of "General Wellness" and involve the diagnosis, treatment, or prevention of diseases, then these devices and related software may need to obtain approval or certification from medical device regulatory bodies (such as the FDA in the U.S. or the CE mark in the EU). Obtaining these certifications typically requires rigorous clinical validation and a lengthy approval process, with very high thresholds and significant costs. Many DePIN projects may try to position themselves at the level of health management and lifestyle improvement to avoid such strict regulations.

These intricate regulatory requirements constitute one of the main obstacles to the development of DePIN x wearable projects, necessitating a high level of compliance awareness and professional legal support from project teams.

Market Acceptance and User Education

• Concept Complexity: Explaining concepts like DePIN, blockchain, cryptocurrency, and data ownership, along with their value propositions, to ordinary consumers is not an easy task. Users may feel unfamiliar, confused, or even distrustful of these technologies. Project teams need to invest significant effort in market education, communicating the advantages of the DePIN model over traditional products (such as data privacy and value sharing) in a clear and straightforward manner.

• Trust Building: Even if users understand the concepts, are they willing to contribute their highly sensitive personal health data to an emerging, decentralized network? Concerns about data breaches, misuse, or token value plummeting are real. Building user trust requires time, transparency, reliable technical safeguards, and successful application cases.

• User Experience Gap: Compared to traditional smart wearable products (like the Apple Watch, Oura Ring) that have undergone years of iteration and possess mature user interfaces and rich functionalities, early DePIN products may lag in usability, stability, functional integration, and aesthetic design. Users may be reluctant to sacrifice familiar and convenient user experiences for potential token rewards. DePIN projects need to strive to enhance the overall quality and user experience of their products while pursuing decentralization and incentivizing innovation.

Future Trends

Despite the numerous challenges, the integration of DePIN and smart wearables presents a clearer and more promising trend:

• Exploration of Data Asset RWA: As blockchain technology, privacy computing, and related legal frameworks continue to mature, personal health data collected, verified, and authorized by users through DePIN networks could become a new type of digital asset. Users may be able to manage, authorize the use of, and even trade their data assets (or their derivative rights) more autonomously, realizing the value of data while protecting privacy. This will also give rise to new data markets and financial innovations based on health data (such as more precise insurance pricing models), but significant regulatory and ethical challenges still need to be overcome.

• Deep Integration of AI + DePIN + Wearables: The combination of these three will generate powerful synergies. DePIN provides AI with unprecedented scale, diversity, and real-time access to real-world health data. AI can extract deep insights from this data, driving more accurate health risk predictions, personalized intervention plans, and diagnostic tools. Smart wearable devices, as the front end for data collection and user interaction, will become smarter, capable of edge computing and real-time feedback. This integration will push personalized health management toward a more proactive, precise, and intelligent direction, truly achieving a transition from "recording health" to "managing health" and even "optimizing health."

Conclusion

The smart wearable market has a solid foundation and enormous growth potential. DePIN offers a potential paradigm shift opportunity and innovative integration model for the smart wearable industry (hardware as nodes, X-to-Earn, data RWA, etc.), addressing pain points such as data silos, privacy concerns, and uneven value distribution under existing models, and opening new spaces for AI-driven personalized health.

The combination of DePIN and smart wearables, though still in its early stages, holds great promise. Investors and entrepreneurs should focus on projects that can build sustainable economic models, possess core technological barriers, actively embrace compliance, and effectively engage communities.

Traditional manufacturers need to consider how to respond to the opportunities and challenges brought by this emerging paradigm and explore possibilities for collaboration or transformation.
