Since the introduction of the first cryptocurrency in 2009 by Satoshi Nakamoto, the world has seen numerous innovations concerning blockchain technology. Industries like fintech, healthcare, supply chain management, retail, agriculture, etc., are the prominent fields leading the world into a new era of creativity and inventions.
According to research, experts believe the blockchain technology market will approach $932 billion in 2032, with a CAGR of 56.1%. The escalating demand for transparent and secure transactions led to the rise in the use of blockchain technology in various industries.
This article will illuminate the different use cases and applications of blockchain technology in fintech, healthcare, and the supply chain.
What is Blockchain?
Blockchain is a distributed ledger network or digital database that tracks digital assets and records transactions. The digital assets can be physical and intellectual properties like cryptocurrencies, NFTs, houses, cars, copyrights, etc.
This ledger network is dispersed among peer-to-peer networks that enable transparent data storage and prohibit centralized control. Businesses and tech experts leverage this technology to track orders, store confidential information permanently, prevent cyberattacks, and more.
Healthcare, logistics, retail, and fintech apps are some of the most prominent software that use blockchain technology. There are four types of blockchain networks: private, public, permissioned, and consortium.
Top Use Cases of Blockchain in 2025 to Look Out For
Blockchain-based Digital Identity
Keeping the identity records for 8.2 billion people worldwide is challenging and cumbersome for digital devices. Companies and startups often access sensitive user data and keep it stored. Protecting this private information from fraud and hackers is a high risk for businesses. Additionally, IoT devices, which collect sensitive data using sensors, monitors, etc., are prone to getting lost and stolen.
That’s when blockchain technologies come into the picture. Its exceptional quality ensures immutability, privacy, fraud prevention, and data security. It includes:
- Safeguard people's private information
- Give unidentifiable people identities
- Monetize personal data to train AI models
- Hide data from the government and companies
- Personal data transmission and verification across different platforms and services, etc.
Decentralized Finance (DeFi) System
DeFi is one of the most prominent blockchain use cases in today’s modern world. It is one of the most popular fintech app ideas that is becoming more popular among several financial institutions because it creates a more open, fair, and unrestricted financial market.
According to research, experts believe the global decentralized market will reach $1250.7 billion by 2034, at a CAGR of 45.8% for 2025-2034. More fintech app development companies are experimenting with DeFi to offer distinct fintech app development services. DeFi enables you to perform all the same tasks as the traditional banking system. It includes:
- Borrowing currencies
- Receiving interest on holdings
- Lending assets
- Buy insurance policies
- Provide liquidity to companies or investors, etc.
Irrefutable Insurance Claims
The process of reclaiming insurance is getting more and more exhausting every day. In addition, the rise in insurance fraud is challenging insurance companies to look for an alternative. By leveraging the blockchain in fintech apps, insurance companies can make the process simpler and faster.
Being an insurance provider, you can hire a healthcare app development company to build insurance and integrate blockchain for:
- Streamline the insurance reimbursement and claiming process
- Create blockchain records for products with ownership history
- Warranty claims for high-insured items on the ledger network
- Improve KYC and AML process
- Mitigate online fraud and ensure transparency, etc.
Encrypted Patient Data Management
Blockchain in healthcare can offer transparency, privacy, security, and quick medical assistance. Telemedicine and patient data monitoring are a few areas where blockchain dominates over other technological solutions.
With telemedicine, doctors can track patient data remotely, consult online or over the phone, and treat patients without compromising the quality of care. Blockchain also:
- Ensure patient data privacy and safety
- Trace drugs in the supply chain right down to the manufacturer
- Reduce the flow of counterfeit medicines
- Allow patients to control their personal information
- Sharing and recording medical data, clinical trials, etc.
Real-time Tracking in Supply Chain
Blockchain in the supply chain and logistics sector can help meet different clientele requirements and execute them effectively. It includes production, packaging, brand labeling, transportation details, etc. It includes:
- Enable multi-level visibility in the supply chain system
- Allow users to detect potential issues in the product
- Monitor product temperature and track shipment medium
- Shipping automation facility
- Detect unauthorized access
- Avoid repurchasing unnecessary drugs
- Integration with other services, etc.
Secured Healthcare Payment
Thanks to smart contracts, blockchain allows payment automation and provides digital security to stocks and bonds. As a result, it ensures transparency, reduces errors, enhances outcomes, and improves efficiency. Businesses with healthcare app ideas use blockchain payment systems to preserve data integrity and improve the app's quality.
Blockchain-based healthcare payment systems have been the talk of the town for quite a few years in the fintech industry. Its benefits include:
- Utilization of cryptographic techniques to avoid unauthorized access
- Prevent private medical data manipulation
- Lower administrative costs and eliminate the need for middle management
- Track payment processing in real-time
- Keep every transaction record
- Allocate resources mindfully and save money, etc.
Healthcare Research & Device Tracking
The healthcare industry has been conducting pioneering research to provide quality care, identify underlying diseases faster, and prevent potential complications. However, accessing that research from credible sources is a tough task in the sea of information.
Blockchain offers a wide range of applications to provide the right information about therapy, treatment timelines, etc. It also includes:
- Record secure and transparent clinical trials
- Mention the credibility of clinical trials and outcomes
- Improve healthcare device logistics management
- Tracking asset ownership at every stage of the supply chain, etc.
Final Thoughts
Traditional digital systems are volatile and fragmented, which requires companies and governments to look for an alternative approach. Governments and enterprises can leverage blockchain’s unified and tamper-proof qualities to ensure high-level data security in finance, healthcare, and supply chain systems.
If you have innovative healthcare or fintech app ideas, you can hire a mobile app development agency that provides blockchain development services. You can outsource your project to them or build an in-house blockchain app development team. It depends on your budget, project complexity, timeline, requirements, etc.
So, why wait? Leverage the future trends in the blockchain industry and start innovating.
