[TL;DR]
- Tech giants like Google and Amazon generate hundreds of billions of dollars from personal data, while users only pay storage fees. Blockchain-based data tokenization resolves this imbalance, enabling individuals to directly participate in the economic value of their own data.
- Decentralized storage built on IPFS and Filecoin distributes encrypted data across global nodes, preventing censorship and service disruption while rewarding storage providers with tokens, thus creating a P2P economy.
- As individuals’ digital activities are tokenized into economic assets, creators can transact directly with fans without platforms, and people worldwide can join the data economy without geographic restrictions, leading to a society of digital sovereignty.
1. Structural Limitations of Centralized Cloud: Data Monopoly and Dependence on Personal Information
1.1. Data Monopoly of Big Tech Platforms: The Real Value Generated from User Data
When we look at today’s cloud services, more than 70% of global data storage is concentrated in the hands of a few giants such as Amazon AWS, Microsoft Azure, and Google Cloud. This concentration is not merely the outcome of market competition, but rather a deliberate design to monopolize the massive economic value generated from user data. Every photo uploaded to Google Drive and every document stored in Dropbox is used as training material for AI models and as raw input for targeted advertising.
For example, Google offers 15GB of free storage while generating $280 billion annually in advertising revenue. This revenue is created by analyzing the personal information and behavioral patterns extracted from users’ emails, photos, and documents. Amazon makes far more money through product recommendations and cloud service optimization based on user data than from direct storage service fees. In fact, cloud service operations are often run near break-even, while the true profit comes from additional services built on top of user data analytics.
The bigger issue is that individuals pay monthly storage fees but cannot participate in the economic value derived from their data. Even if one person’s 20 years of accumulated photos and documents have contributed to Google’s AI training and advertising revenues, that individual still receives storage shortage warnings and must pay extra fees. Although the actual owner of the data is the individual, all the added value generated from it is monopolized by the platform, cementing a distorted structure.
As the data economy grows, this value monopoly deepens. Since everyday digital activities are all stored on the cloud, these corporations accumulate comprehensive datasets about people’s preferences, relationships, financial status, and even health conditions. The result is a paradox: individuals provide their most private information and even pay to store it, yet gain nothing from the economic value it creates.
1.2. Dependence on Platforms and Data Lock-In for Individuals and Companies
Once data is entrusted to a particular cloud platform, moving it elsewhere is far more complex and costly than expected. Transferring 100,000 photos from Google Photos to Amazon Photos, for instance, involves not only downloading and re-uploading but also facing technical barriers and time costs. File format compatibility, metadata preservation, folder structure maintenance, and API integration create technical challenges that ordinary users find nearly impossible to overcome.
In enterprise environments, this dependency is even more severe. A startup that has built its infrastructure on AWS may require months of work and millions of dollars to migrate to Azure. Database schema changes, application code modifications, and reconfiguring security settings all depend on platform-specific technologies and services, making actual migration nearly impossible. Cloud providers deliberately strengthen interoperability within their own ecosystems while limiting compatibility with competitors, effectively locking customers in.
For individual users as well, decades of emails, tens of thousands of photos, and countless documents and backups accumulate on a single platform, making it impossible to leave. When all digital assets—from family photos to critical work documents—depend on a single Google account, an account suspension or service termination exposes the entire digital life to risk. Cases where people have permanently lost years of records due to hacking or account deactivation by Google or Apple continue to occur.
This lock-in fundamentally weakens the bargaining power of both individuals and companies, leaving them powerless against unilateral policy changes by cloud providers. If Amazon raises storage fees or Microsoft changes service terms, users who have already entrusted all their data have no choice but to accept. More seriously, when a provider withdraws services from a specific country or restricts access in compliance with government regulations, users may completely lose control over their own data.
1.3. Lack of Transparency and the Risk of Censorship: Problems of Centralized Data Control
Most cloud service users have no idea where exactly their data is stored, how it is backed up, or who can access it. Providers use vague terms such as “secure data centers” or “encrypted storage,” but specific details of data handling remain undisclosed under the excuse of trade secrecy. Users cannot know whether their files are stored in U.S. servers, European servers, or distributed across multiple locations.
This opacity raises serious concerns about data security and privacy. As revealed by Edward Snowden in 2013, major cloud providers had been cooperating with government mass-surveillance programs, while users remained completely unaware. Companies like Google, Microsoft, and Apple granted national security agencies access to user data but were legally barred from disclosing it. This means personal files stored in the cloud may be accessed or analyzed by third parties without the owner’s knowledge—a structural risk inherent in centralized systems.
Even more troubling is unilateral content restriction and censorship driven by platform policies or algorithmic changes. With AI-based content scanning increasingly deployed by services like Google Drive or Dropbox, personal files are automatically analyzed, and access may be restricted or deleted based on opaque criteria. There have been reported cases where academic research materials or artistic works were misclassified as “inappropriate content” by automated systems, leading to account suspensions.
Geopolitical and legal differences across countries also directly affect individual data access. In China, Google services are entirely blocked, making it impossible for users to access their existing data. Following the Russia–Ukraine war, users in certain regions experienced restrictions or suspensions of cloud services. As a result, personal data and digital assets face the very real risk of becoming inaccessible due to geopolitical conflicts or shifting government policies.
2. A New Data Ecosystem Proposed by Decentralized Storage
2.1. Tokenization of Personal Data and Establishing Direct Ownership
The fundamental solution to the problems of traditional cloud systems begins with granting individuals clear and non-transferable ownership of their own data. Through blockchain-based data tokenization, every piece of digital content created by an individual can be transformed into a unique cryptographic token, ensuring that the creator permanently retains ownership and control. Photos taken, documents written, and content produced can all be tokenized as NFTs, enabling complete transparency over who accessed the data, when, and for what purpose.
In such a tokenized system, the process of data utilization and monetization fundamentally changes. If platforms like Google or Meta wish to use personal data for AI training or targeted advertising, they must directly pay the data owner for that usage.
For example, if an individual’s fitness data is used to train a healthcare AI model, corresponding token rewards are issued in real time. If travel photos are leveraged in tourism recommendation algorithms, the original owner is compensated in proportion to the value created. A fair distribution mechanism ensures that data creators directly participate in all economic value derived from their information.
Clarified data ownership also transforms how individuals manage digital assets. Instead of relying on platforms to store their data, people will actively classify, evaluate, and strategically manage their digital assets. High-quality, original, and rare content will be valued more highly in the market, encouraging individuals to approach content creation and data generation more deliberately and strategically.
Tokenized data ownership also creates digital assets that can be inherited across generations. A lifetime’s worth of photos, documents, and creative works will be recognized as valuable economic assets that can be passed on to descendants. Furthermore, personal data may gain historical or cultural significance over time, continuously appreciating as a long-term investment asset.
2.2. Decentralized Networks and Autonomous Data Management Systems
Alongside data ownership, what is needed is a technical infrastructure that enables secure and efficient data storage and management without relying on centralized servers.
A decentralized storage network based on IPFS (InterPlanetary File System) allows millions of personal computers and servers worldwide to form a massive collective storage space, creating a fully decentralized cloud system that does not depend on any specific corporation or data center. Files are encrypted and split into fragments stored across multiple nodes, ensuring integrity and accessibility even if some servers fail or are attacked.
Protocols such as Filecoin and Arweave sustain these networks through economic incentives. Individuals who contribute unused storage space receive token rewards, while users who store data pay for the service with tokens.
This market-driven model enables storage services that are cheaper and more secure than centralized data centers. It dismantles the high-cost structure of traditional cloud services and establishes a P2P storage economy directly connecting storage providers and consumers.
The greatest strengths of decentralized networks are censorship resistance and permanent accessibility. Since data is distributed across hundreds of nodes worldwide, it becomes nearly impossible for any government or authority to delete or block access. Once stored on the network, data is continuously replicated and verified, ensuring permanence regardless of provider policy changes or business shutdowns.
The combination of encryption and sharding maximizes security. Once uploaded, a file is automatically encrypted, split into multiple fragments, and stored across different regional nodes. Each fragment alone reveals nothing about the original file, and even with all fragments collected, decryption is impossible without the owner’s private key.
As a result, individuals gain full privacy protection and secure, global access to their data at any time.
2.3. Contribution-Based Token Rewards and Decentralized Storage Mining Mechanisms
For a decentralized storage network to grow and remain stable, an economic mechanism is needed to accurately measure contributions and fairly distribute rewards. Token rewards are automatically allocated based on factors such as the amount of storage provided, data transmission speed, uptime, and overall contribution to network stability.
This goes beyond simply offering disk space—rewards are determined by how effectively participants support other users’ data access, how they enhance distribution and redundancy, and their real-time performance.
Such a contribution-based reward system encourages natural role specialization among participants. Some may focus on providing large-scale storage, others on high-speed data transmission, and still others on monitoring network health and verifying security. From individuals offering spare storage on personal computers to professional operators managing large-scale data centers, everyone can participate at their own level, creating an inclusive ecosystem.
Additional revenue models emerge through providing AI training data and sharing computing resources. Individuals can earn token rewards by offering anonymized data for AI training or by contributing computing power for distributed AI learning and data processing. This way, personal digital resources generate value across storage, transmission, and computation, forming a comprehensive model of participation in the digital economy.
Over the long term, individual contributions to decentralized storage accumulate into a source of passive income. A stable node set up in youth can provide steady revenue for decades, while contributed data and computing resources become part of successful projects, with participants sharing in their outcomes. Ultimately, individuals’ digital assets and technical contributions together become the foundation for long-term value creation, transforming storage services into a comprehensive digital economy ecosystem.
3. Application Scenarios of Decentralized Storage by Sector
3.1. Personal Data Management: Complete Ownership of Lifetime Digital Assets
When we consider the tens of thousands of photos and documents individuals currently store on Google Photos or iCloud, it becomes clear that all of this data is effectively under the control of platform corporations. In a decentralized storage system, every digital asset is secured within an encrypted personal data vault, accessible only to its rightful owner, with no outside entity able to unilaterally delete or block it. From family photos to critical work documents and private journals, everything is safeguarded with blockchain-based proof of permanent ownership.
The greatest strength of a personal data vault lies in complete control over data use and monetization. For example, someone who has accumulated ten years of exercise records and health data can anonymize and license it to healthcare research institutes or AI developers in exchange for fair compensation.
Travel photos and review data can be provided to tourism platforms, while food pictures and restaurant experiences can be monetized by sharing with recommendation services. Everyday digital activities become potential revenue sources, marking a paradigm shift in which data generation itself is recognized as an act of economic value creation.
Decentralized storage–based personal data management also makes digital inheritance across generations possible. Currently, the only way to pass down digital assets is by sharing passwords for accounts like Google or Apple. In contrast, a blockchain-based system enables automated inheritance through smart contracts. Parents’ lifelong collections of photos, documents, and creative works can be securely transferred to their children, along with ongoing revenues generated by those assets.
The temporal increase in the value of personal data is another important aspect. Photos taken two decades ago with a digital camera or personal records from the early internet era may gain cultural or research significance over time, continually appreciating in value. A person’s everyday digital records can become valuable resources for future historians or sociologists, with licensing revenues returning to the original owner or heirs. This creates a new form of long-term investment asset.
3.2. Enterprise Data Storage and AI Training: Decentralized Enterprise Solutions
In business environments, adopting decentralized storage brings not just cost reduction but fundamental improvements in data security and business continuity. Traditional cloud services rely on data centers in specific regions like AWS or Azure, leaving them vulnerable to natural disasters or political changes. In contrast, decentralized storage disperses critical corporate data across hundreds of nodes worldwide.
For instance, a Korean fintech startup can store data across nodes in Europe, North America, and Southeast Asia, fully mitigating regional risks and ensuring that no single point of failure can disrupt operations.
The advantages become even clearer in inter-company data collaboration. Today, businesses on different cloud platforms face difficulties in sharing data securely, but blockchain-based access control enables fine-grained permissions.
A pharmaceutical company developing an AI model can access anonymized patient data from hospitals under conditions predefined in smart contracts—such as scope, duration, and purpose of use—with automatic licensing payments to data providers. This allows core corporate data assets to be safely utilized without leakage while ensuring fair compensation, creating a trust-based data economy.
Building decentralized datasets for AI training also introduces new revenue models. An e-commerce company’s consumer behavior data, a manufacturer’s sensor data, and a financial firm’s transaction patterns can all be anonymized and provided for AI model training, earning token rewards proportional to the quality and utility of the data. When combined datasets lead to more accurate AI models, additional rewards are distributed fairly based on contribution.
Decentralized storage–based enterprise solutions also excel in regulatory compliance. To meet GDPR’s data localization requirements or other national privacy laws, companies can configure storage so that certain datasets remain within specific regions. If necessary, data can be completely deleted or locked by discarding encryption keys. Transparent audit trails of all data processes can be automatically provided to regulators using blockchain records.
3.3. Creative Works and Intellectual Property Protection: Decentralized Content Distribution Platforms
One of the biggest challenges for digital creators is securing full ownership and revenue rights over their works. On platforms like YouTube, Instagram, and TikTok, creators generate content but platforms take the majority of ad revenue, leaving creators with only a small share. In contrast, decentralized storage–based content platforms enable creators to tokenize their works as NFTs, establish full ownership, and transact directly with audiences without intermediaries.
Blockchain-based proof-of-origin systems fundamentally prevent copyright infringement. As soon as a creator uploads a work, its hash and timestamp are permanently recorded on the blockchain, providing indisputable evidence of authorship. Even the distinction between AI-generated images and human-created artworks can be transparently verified through metadata of the creative process, protecting originality and authenticity.
Direct transactions between creators and consumers without intermediary platforms fundamentally reshape the content economy. A webtoon artist can store their work on decentralized storage, and readers can access it directly by paying in tokens. A music artist can issue an album as an NFT and sell it directly to fans. Without intermediaries or platform fees, creators retain the majority of their works’ value while consumers gain access to quality content at lower prices—creating a win-win model.
Decentralized systems also enable sophisticated licensing for derivative works and remixes. For example, if an artist’s song is remixed or covered by another creator, smart contracts automatically distribute royalties to the original artist while ensuring fair compensation for the secondary creator. Such automated revenue-sharing systems promote collaboration and mutual growth across the creative ecosystem, ensuring all participants receive fair rewards and fostering a sustainable creative economy.
4. The Technical Infrastructure Supporting Decentralized Storage
4.1. Distributed Hash Tables and Content Addressing Systems
At the core of decentralized storage lies the shift from a traditional location-based addressing system to a content-based addressing system. IPFS (InterPlanetary File System) identifies each file with a unique hash value, so the file’s content itself becomes its address, rather than its storage location. Even if the same file is replicated across hundreds of nodes worldwide, all copies share the same hash value, allowing users to retrieve the file from the nearest and fastest node.
Distributed Hash Tables (DHTs) are the key to efficiently managing this content addressing. Each node in the network is responsible for part of the hash space, eliminating the need for a central server to locate files. When a user requests a file, the DHT quickly identifies nodes that store it and selects the optimal source based on latency and node health.
Merkle trees and linked data structures enable efficient distributed storage of large files. A large file is split into smaller blocks, each independently hashed and stored. If only part of the file changes, only the modified blocks need to be re-uploaded, avoiding redundant storage. This is also effective for version control and deduplication: even if multiple users store similar files, shared blocks are stored only once, greatly improving network storage efficiency.
The strength of content addressing is particularly clear in censorship resistance and permanent accessibility. Since addresses are based on content rather than location, blocking a server or domain cannot restrict access to the file itself. Any node in the network can provide the content. As a result, personal data is truly decentralized, with no single point of failure or censorship attempt able to block access—ensuring a robust system of information preservation.
4.2. Blockchain-Based Data Integrity and Ownership Proof Systems
Decentralized storage guarantees data integrity and ownership through blockchain. When a file is uploaded, its hash is generated and recorded on the blockchain, and all subsequent access, modifications, and sharing activities are stored immutably. A photo taken 10 years ago or a document written 5 years ago can be verified for authenticity, providing indisputable proof in copyright disputes or forgery cases.
Smart contracts enable automated licensing, unlocking new possibilities for data utilization. For instance, when personal fitness data is shared for healthcare research, usage purpose, duration, and anonymization level can be predefined. The smart contract then automatically enforces these conditions, revoking access upon violation. Once the research concludes, the promised compensation is automatically delivered to the data owner, with the entire process transparently recorded on the blockchain for future audits.
Multi-signature–based shared ownership management is especially useful in corporate or team environments. For critical project files or co-created works, ownership can be distributed among multiple parties, with modifications or external sharing requiring a predefined number of signatures. For example, two out of three approvals may be required for sharing a document, or three out of five approvals for implementing important changes—enabling democratic yet secure data management.
Backup and recovery also benefit from blockchain’s consensus mechanisms. When files are distributed across nodes, their integrity is continuously verified by other nodes. If corruption or tampering is detected, the system automatically restores data from intact copies. This ensures that critical data remains protected from technical failures or malicious attacks, while every data process remains transparent and verifiable.
4.3. Privacy Protection Architecture Through Encryption and Sharding
Privacy protection in decentralized storage is achieved through multi-layered encryption and intelligent sharding. When a file is uploaded, it is first encrypted with the owner’s private key, then split into multiple fragments, each encrypted again with different keys—creating a dual security structure. Individual fragments reveal nothing about the original file, and even if all fragments are gathered, decryption remains impossible without the owner’s private key.
Zero-knowledge proof (ZKP) techniques allow validation of data without exposing private information. For example, when medical data is shared for research, ZKPs can mathematically prove that the data meets required conditions without disclosing sensitive attributes like age, gender, or disease history. This enables innovative models of data utilization that protect privacy while ensuring statistical validity.
Dynamic encryption-level adjustment further optimizes security. Everyday photos or notes may be encrypted at standard levels for fast access, while financial or legal documents can be secured with the highest encryption and additional authentication steps. Depending on user preferences, certain file types may require biometric verification or hardware keys, balancing convenience and security.
Geographically distributed sharding strategies also enhance privacy protection. Users can configure fragments to be stored only in specific regions for compliance, or widely dispersed to mitigate the risk of political changes or regulatory restrictions. As a result, individuals retain full control over their data, ensuring that no single institution or government can unilaterally access or censor it—realizing true data sovereignty.
4.4. Optimized User Experience and Wallet Service Integration
For decentralized storage to achieve mainstream adoption, user experience must be seamless enough that ordinary users need not deal with blockchain complexities. WaaS (Wallet-as-a-Service) plays a crucial role here by allowing users to pay storage fees with existing credit cards or bank transfers, while the backend automatically converts payments into appropriate tokens and distributes them to network nodes.
Complex processes such as key management, token transfers, and gas fee calculations are abstracted away, so users can enjoy decentralized storage in the same way they use traditional cloud services.
Cross-chain interoperability is also essential for user experience. Moving data between different decentralized storage protocols (e.g., Filecoin, Arweave, Sia) or transferring assets across blockchain networks (e.g., Ethereum, Polygon) can be completed with a single click. Real-time monitoring of performance and cost across protocols ensures that users are always offered the most optimal storage solution, with seamless migration when needed.
Compatibility and migration tools with existing cloud services are another critical element. Files stored on Google Drive or Dropbox can be gradually migrated to decentralized storage while retaining folder structures, sharing settings, and access permissions. Users can continue using familiar applications to access and edit files directly, enjoying the benefits of decentralized storage without disrupting their workflows.
Multi-device synchronization and offline support provide a consistent experience across mobile and desktop environments. Photos taken on a smartphone are automatically encrypted and stored on the decentralized network, instantly accessible from a laptop. Frequently used files are cached locally, enabling smooth use even under unstable internet conditions. Ultimately, users can naturally enjoy a safer and more economical decentralized storage experience without being burdened by technical details.
5. Challenges of Decentralized Storage and the Future of Data Sovereignty with AI Integration
5.1. Resistance from Existing Cloud Providers and Regulatory Barriers
Tech giants such as Amazon, Google, and Microsoft are unlikely to sit back while decentralized storage threatens their multi-trillion-dollar revenue models. Armed with enormous capital, they attempt to neutralize the competitive edge of decentralized storage through short-term dumping strategies. Examples include Google offering unlimited storage or Amazon drastically cutting S3 prices, undermining users’ incentives to switch to new systems. Moreover, these companies continue to poach key developers or acquire promising decentralized storage startups in an effort to delay technological progress.
Their influence is equally strong in lobbying regulators. Attempts have already been made to classify token transactions in decentralized storage as securities, thereby subjecting them to complex regulations, or to impose stringent data security standards that only centralized systems can realistically meet. Laws like the EU’s GDPR or China’s Data Security Law are often enforced more strictly against decentralized systems, adding extra layers of complexity and cost for global service providers.
Geopolitical conflicts over data sovereignty also obstruct the growth of decentralized storage. Governments are increasingly strengthening localization requirements, mandating that citizens’ data be stored within national borders. For example, Chinese users’ data must remain in China, and European users’ data within the EU. These restrictions undermine one of decentralized storage’s greatest strengths—geographic distribution and censorship resistance.
Uncertainty surrounding cryptocurrency and token regulations is another ongoing risk. Tax treatment for token rewards earned by individuals participating in decentralized storage differs by jurisdiction, and the legal status of tokens remains ambiguous, discouraging corporate adoption. As a result, even though the technology is ready, it may take considerable time for legal and political environments to mature, giving incumbents extra time to strengthen their monopolies.
5.2. Technical Maturity and Limitations to Large-Scale Adoption
Although decentralized storage is theoretically robust, several technical hurdles remain before billions of global users can adopt it simultaneously. At present, the throughput and scalability of major decentralized storage protocols do not match the levels of AWS or Google Cloud. For example, IPFS’s content retrieval speed or Filecoin’s recovery time is often slower than traditional cloud services, making it less viable for real-time collaboration or enterprise-scale processing of large datasets.
The lack of network effects also presents a practical limitation. For decentralized storage to be competitive, it requires a critical mass of nodes and users. In its early stages, however, participation incentives are insufficient, and usability is relatively poor. Individuals may find it difficult to earn meaningful profits from offering storage, while companies hesitate to entrust critical data to networks whose stability is not yet fully proven.
General users’ lack of technical literacy and trust is another obstacle. Even with WaaS and user-friendly interfaces solving much of the complexity, situations still arise where a basic understanding of blockchain, encryption, or token economics is required. Older generations or those unfamiliar with technology may find the entry barrier higher than with traditional cloud services, delaying mass adoption.
Concerns over data loss or hacking also discourage corporate adoption. In centralized systems, service providers clearly bear responsibility and offer compensation, but in decentralized networks, liability is ambiguous and recourse is limited. Industries requiring high levels of data security and regulatory compliance—such as finance, healthcare, and law—are likely to remain conservative until the safety and reliability of decentralized storage are thoroughly proven.
5.3. Societal Transformation Driven by AI-Integrated Decentralized Storage Economy
Despite these technical and regulatory challenges, the direction of societal change driven by the integration of AI and decentralized storage is already becoming clear. Personal data will be recognized as a true economic asset, and digital activities themselves will become sources of income. Instead of giving away personal information for free to companies like Google or Facebook, individuals will receive fair compensation. This will dismantle structures where digital inequality directly translated into economic inequality, and digital assets will become a new ladder for upward mobility.
The creator economy will also undergo fundamental restructuring. Creators will be able to connect directly with fans and monetize their work without intermediaries such as YouTube, Instagram, or TikTok. Independent creative ecosystems will emerge, no longer dictated by platform algorithms or policies. Streamers may build decentralized storage–based channels to transact directly with subscribers, and webtoon artists will sell works straight to readers without intermediaries—ushering in a new era of content distribution.
At a global level, digital sovereignty will be redefined. Individuals in developing countries will be able to participate directly in the global economy through their data and digital assets, narrowing traditional economic gaps between nations and regions. An African farmer could monetize agricultural data by contributing it to global AI research, while a Southeast Asian creator could transact directly with fans worldwide—creating new forms of borderless economic participation.
In the long run, even the ownership and governance structure of the internet itself will be decentralized. The infrastructure currently controlled by a handful of Big Tech corporations will be transformed into a globally distributed network maintained by voluntary participation from individuals. This will allow anyone to access information and express opinions freely, without censorship or service disruption—realizing the internet as a true global public good. Ultimately, the restoration of data sovereignty will bring not just technological change, but a fundamental societal transformation—ensuring economic freedom, freedom of expression, and equal participation in the global economy.
