Blockchain technology, first introduced in 2008 with the release of the Bitcoin whitepaper by Satoshi Nakamoto, has evolved far beyond its financial origins. While cryptocurrencies continue to gain traction, blockchain’s core strengths—decentralization, immutability, and transparency—are now being harnessed across multiple industries. From supply chain tracking to secure medical data exchange, blockchain is enabling more efficient, trustworthy, and user-centric systems.
This article explores four real-world applications of blockchain in Taiwan, showcasing how the technology is transforming retail, insurance, healthcare, and music copyright management. These use cases highlight practical implementations that solve real industry challenges while enhancing user experience and data integrity.
Case 1: New Retail Consortium Blockchain Service
Empowering a consumer-centric supply chain with transparent, multi-party data sharing
A pioneering initiative led by the Institute for Information Industry (III), Hsinchu Logistics (a leading logistics provider), NetOne Communications (a customer engagement expert), and China Trust (a financial services leader) has created a blockchain-powered smart retail ecosystem. This collaboration integrates logistics, data analytics, and financial services into a unified platform driven by consumer data.
The system operates on a decentralized network where brand owners, logistics providers, banks, and marketing technology firms can securely access and share transactional data. Enterprise agents use both symmetric and asymmetric encryption to transmit sensitive information across multiple parties simultaneously, ensuring only authorized entities can decrypt and view the data.
Industry Benefits
"End-to-end, customer-centric commerce excellence."
- Brands gain deeper insights into consumer behavior and delivery performance, enabling more personalized marketing and improved service.
- Consumers can track product authenticity and delivery status in real time, increasing trust in purchases.
- Logistics providers share shipment and delivery confirmation data seamlessly across the network.
- Banks verify and process payments with greater accuracy and speed using tamper-proof transaction records.
- Marketing and data analytics firms can trace data usage, authorization history, and ad delivery logs within a transparent ecosystem.
- Third-party researchers gain secure access to anonymized transaction data for market analysis.

This model shifts retail from a linear supply chain to a dynamic, data-driven network where all stakeholders benefit from shared, secure information—proving that blockchain is more than just a financial tool.
Case 2: Insurance Claims Blockchain Service
"Data usage is controlled entirely by the policyholder’s consent."
Taiwan Life Insurance partnered with Kaohsiung Veterans General Hospital to launch the eClaim blockchain service, a secure platform that connects healthcare providers and insurers. With the patient’s explicit authorization, medical records required for insurance claims—such as diagnosis reports, imaging data, or treatment summaries—are directly transmitted to the insurance company via blockchain.
Instead of manually collecting paper documents from hospitals, policyholders now grant digital consent through a secure interface. The中信金融 (CTBC Financial) Group has also adopted blockchain to transmit claim documents, accelerating the assessment process and significantly reducing payout times.
Industry Benefits
"Faster claims processing, better customer experience."
- Policyholders control what data is shared and can view exactly which records were accessed and when—every action is logged on the blockchain.
- No more hospital visits for medical records—the entire claims process is paperless and streamlined.
- Blockchain ensures trust in cross-industry data exchange, enabling faster claims settlement and improved service quality.
- Patients gain portable medical records that can be used for future consultations, enhancing continuity of care.
This application demonstrates how blockchain empowers individuals with data sovereignty while improving operational efficiency for insurers and healthcare providers alike.

Case 3: Remote Island Medical Record Exchange
"Instant data authorization makes patient records more accessible than ever."
In remote areas like Taiwan’s outlying islands, accessing medical records has traditionally been difficult due to infrastructure limitations. A new blockchain-based solution uses digital certificates and smart contracts to enable paperless consent forms. Patients use a mobile app to sign consent forms with their private key—the signed record is stored across the blockchain network, ensuring it cannot be altered.
This system eliminates the need for the traditional "three-card" requirement (medical personnel card, NHI card, and machine card) for accessing electronic health records. Doctors on mobile clinics can now instantly retrieve patient histories, medication lists, and treatment plans.
Industry Benefits
"Blockchain-powered digital consent for seamless healthcare access."
- No physical cards or location restrictions—the platform works on smartphones, tablets, and computers.
- During remote medical missions, doctors use a proxy authorization app to instantly access patient data, adjust prescriptions, and issue new treatment recommendations in real time.
- Patients can revoke or modify access permissions at any time, thanks to blockchain’s dynamic consent feature. All changes are immediately recorded and notified across the network.
- The system can be extended to other digital medical consents, such as surgery authorization or clinical trial participation.
This case proves that blockchain can bridge healthcare gaps in underserved regions while maintaining strict data privacy and compliance.
Case 4: Digital Copyright Management in Music
"Transparent, fair, and instant royalty distribution across borders."
Musicians and composers often struggle with opaque royalty systems and delayed payments. Blockchain offers a solution by recording every stage of music creation—lyrics, compositions, audio files—on an immutable ledger. Smart contracts define ownership percentages among collaborators and automate royalty distribution directly to each party’s digital wallet.
When a song is used—whether streamed, licensed for commercials, or played in public—the system triggers automatic payments based on pre-defined rules. This eliminates intermediaries and reduces disputes over rights ownership.
Industry Benefits
"Blockchain as irrefutable proof of creative ownership in the digital age."
- The decentralized nature of blockchain ensures transparent tracking of copyright declarations, usage history, and licensing terms.
- Artists can update licensing fees dynamically using new smart contracts, creating a more flexible and responsive market.
- In case of copyright disputes, blockchain-stored creation records serve as court-admissible evidence.
- Data analytics tools help creators understand how their music is being used globally, revealing new monetization opportunities.
This application not only protects creators but also fosters a more vibrant and equitable music ecosystem.
Frequently Asked Questions (FAQ)
Q: How does blockchain ensure data security in healthcare?
A: Blockchain uses cryptographic hashing and distributed storage to make records tamper-proof. Each transaction is time-stamped and linked to the previous one, ensuring full traceability and integrity.
Q: Can blockchain really speed up insurance claims?
A: Yes. By automating data verification through smart contracts and secure sharing between hospitals and insurers, blockchain reduces manual processing from days to minutes.
Q: Is blockchain only useful for financial applications?
A: No. While it originated with cryptocurrency, blockchain’s ability to provide transparency, immutability, and decentralized control makes it ideal for supply chains, healthcare records, intellectual property, and more.
Q: How do artists benefit from blockchain-based copyright systems?
A: They gain clear ownership proof, automated royalty payments, real-time usage tracking, and greater control over licensing terms—reducing dependency on third parties.
