What is Data Tokenization, and Why is It Crucial?

 

In today’s digital world, data is hailed as the “new oil,” with its potential value spanning all aspects of economic, social, and technological development. However, in practical applications, the true value of data remains untapped due to restrictions in circulation, privacy concerns, and ambiguous ownership. To solve these problems, Data Tokenization has emerged as a solution.

 

Data Tokenization transforms data into blockchain-based digital assets, enabling it to circulate in global markets and unleash its potential value. This not only creates new economic models for data providers and consumers but also offers innovative opportunities for data-driven industries. This article will discuss the importance and vast potential of Data Tokenization in simple and accessible terms from multiple perspectives.

 

I. Origins and Definition

 

1. The Origins of Data Tokenization

 

The concept of Data Tokenization originated from breakthroughs in blockchain technology, especially the applications of Ethereum smart contracts and non-fungible tokens (NFTs). Supported by Ethereum and similar platforms, developers can use smart contracts to empower data, transforming it into tradable assets.

 

Traditional methods of data exchange rely on centralized platforms. For example, advertising data is controlled by tech giants like Google and Facebook, while user-generated data is stored and traded privately by these platforms. This centralized model makes it difficult for data producers (such as users) to benefit from their data, while platforms earn significant profits. To break this monopoly, blockchain developers proposed the concept of Data Tokenization.

 

At its core, Data Tokenization decentralizes the process of turning data into tradable digital assets. Early implementations focused on protecting user data in the advertising industry and building decentralized data markets. In recent years, with the rise of DeFi and Web3.0, blockchain technology has become a driving force for Data Tokenization.

Example: The Challenges of User Data

Imagine you share personal information on social media, such as your hobbies and shopping habits. This data is analyzed by advertising platforms to push targeted ads, yet you receive no benefit from it. With Data Tokenization, your behavioral data becomes your asset, allowing you to choose whether to sell or share it for profit.

 

 

2. Definition of Data Tokenization

 

Data Tokenization is the process of converting data into blockchain-based digital assets, enabling explicit ownership and usage rights to be established and allowing data to circulate in markets. Previously, data was merely information, lacking effective monetization pathways. Through tokenization, data becomes globally tradable, increasing its liquidity and value. Using smart contracts, data owners can authorize usage while ensuring privacy and security during transactions.

Simply put, Data Tokenization converts data into blockchain-based digital assets. These digital assets (tokens) represent ownership or usage rights of the data and can be bought, sold, or traded like currencies or stocks.

 

Analogy: Think of it as turning a book into shares. In the past, publishers and bookstores profited from the book, while you, the author, earned very little. With Data Tokenization, you could divide the book into 100 shares and sell them to interested investors. Investors could enjoy the book’s content and earn dividends, while you receive income. This example illustrates the essence of Data Tokenization.

 

 

II. Market Background and Motivation

 

1. The Rapid Rise of the Data Economy

 

Data has become a core resource driving modern economic development. Whether it is AI algorithm training, targeted advertising, or supply chain optimization, data plays a vital role. For example, in 2022, the global digital advertising market exceeded $500 billion, driven by user data.

 

However, the current data transaction model faces several major problems:

• Difficulty in quantifying data value: How can the actual value of data be assessed?
• Insufficient privacy protection: Frequent data breaches reduce trust in data transactions.
• Ambiguous ownership: Platforms control data, while creators cannot profit from it.

 

The emergence of Data Tokenization marks a critical turning point in the data economy. By assigning explicit ownership and circulation attributes to data, it addresses the core issues of traditional data markets.

 

The data economy is expanding rapidly, with the global data transaction market reaching $800 billion in 2024 and expected to grow to $1.5 trillion by 2030. As fields such as AI, IoT, and digital advertising flourish, data becomes a critical resource for supporting these industries. Yet, the circulation and trading of data remain heavily reliant on centralized platforms. These platforms often monopolize data ownership and profits, leaving its potential value unrealized.

 

In November 2024, the world’s largest advertising company, WPP, announced a partnership with Ocean Protocol to promote Data Tokenization in the advertising industry. By tokenizing data, advertisers can better evaluate target audiences and deliver more personalized ads.

 

Case Study: The Economic Cost of Data Breaches In 2018, Facebook suffered a massive public backlash due to the Cambridge Analytica scandal. This incident highlighted the abuse of user data by centralized platforms. If data were tokenized and controlled by users, such incidents could be significantly reduced, enabling users to benefit from their data and control its usage.

 

2. Technological Driving Forces

 

The development of blockchain technology has provided the technical foundation for Data Tokenization:

• Smart contracts: Enable automated data transactions and authorizations without human intervention.
• Decentralized storage: Solutions like Filecoin and IPFS make large-scale data storage feasible.

As blockchain evolves, advancements in smart contracts, decentralized storage, and privacy technologies have transformed Data Tokenization from theory to practice. In 2024, many organizations began adopting decentralized storage solutions like Filecoin and IPFS to tokenize and store user data. These decentralized networks significantly enhance data security and reduce dependency on centralized systems.

 

Example: The Role of Blockchain in Data Storage

Traditional data storage systems, such as cloud services (e.g., Google Drive, AWS), are prone to attacks or tampering. Decentralized storage technologies (e.g., Filecoin) distribute data across global nodes, significantly improving security. This makes Data Tokenization both practical and efficient.

 

 

 

3. Societal and Legal Needs

 

With the implementation of GDPR (General Data Protection Regulation) and CCPA (California Consumer Privacy Act), public awareness of data privacy has reached unprecedented levels. Data Tokenization empowers users to regain control of their data while facilitating legal and secure transactions.

For instance, tokenized medical data allows patients to sell their anonymized health information to research institutions without concerns about privacy breaches. Patients can selectively share specific disease-related data and use smart contracts to ensure secure usage.

 

 

 

 

III. Position and Value

 

Data Tokenization contributes significantly to the global data economy, offering the following key benefits:

①Explicit Ownership

Data Tokenization assigns unique digital identifiers to each dataset, creating a transparent ownership record. This builds trust in data markets. For example, just as buying a house requires a property deed, Data Tokenization provides a “digital property certificate” for datasets.

②Enhanced Liquidity

Traditional data is restricted in circulation due to storage and transaction limitations. Tokenized data can flow like currency, reducing transaction costs.

Example: In 2024, European insurance giant Allianz collaborated with Filecoin to tokenize customer health and fitness data. This enabled the creation of personalized insurance products while reducing reliance on third-party intermediaries.

Data Tokenization can change this dynamic by ensuring the security and transparency of user data through blockchain technology. It allows users to selectively sell or share their data while protecting their privacy and earning profit.

 

For example, in 2024, Google, the world’s largest digital advertising platform, announced a partnership with a decentralized advertising platform. The collaboration aims to use Data Tokenization to help advertisers better evaluate advertising effectiveness while ensuring data transparency and protecting user privacy.

Case Study: Brave Browser and BAT Tokens

The Brave browser uses blockchain technology and Basic Attention Tokens (BAT) to tokenize advertising data and user attention. Users earn BAT tokens by viewing ads, while advertisers access precise audiences at lower costs. Compared to traditional advertising models, this decentralized data transaction mechanism addresses issues of data privacy and reduces intermediary costs.

 

 

2. Finance and Insurance

 

In the financial sector, the application of Data Tokenization is becoming increasingly mature. Financial institutions rely heavily on data to assess risks, formulate strategies, and determine pricing, most of which is provided by third parties. With Data Tokenization, financial companies can directly acquire individual or enterprise data, reducing intermediaries, enhancing data liquidity, and allowing users to earn profits from their data.

 

For instance, personal health data, credit scores, and consumption behavior can all be managed and traded through blockchain and Data Tokenization. Insurance companies can use tokenized user data to create personalized insurance products, while users earn token rewards for sharing their data.

Case Study: Healthereum and Medical Data

Healthereum is a decentralized platform that tokenizes medical health data. It enables users to sell anonymized health data to insurance companies or medical institutions while protecting their privacy. This approach improves data utilization and ensures that users—data providers—benefit from their contributions.

 

3. Supply Chain Management

 

The supply chain is another industry that can greatly benefit from Data Tokenization. In traditional supply chain management, access to data is often restricted, leading to inefficiencies and limited transparency. By using blockchain technology and Data Tokenization, data transparency and real-time sharing across the supply chain can be achieved. This improves efficiency, reduces costs, and minimizes fraud.

 

For instance, tokenizing supply chain data can track the production, transportation, and delivery of goods, providing consumers with transparent information while rewarding businesses with data tokens for participation in the supply chain.
