Blockchain technology has been a game changer for transacting, sharing information, and defining trust in the rapidly evolving digital world. Blockchain platforms serve as a digital database or ledger system that fosters transparency and accountability in a business network by recording transactions and tracking assets.
While blockchain applications have been largely associated with cryptocurrency software and bitcoins, the technology has the power to revolutionize several industries by offering secure and decentralized solutions.
What are the top applications of blockchain technology?
Blockchain technology is being used across almost every industry, including:
Businesses can build applications of blockchain for any purpose, like digital payments or supply chain, through blockchain platforms, often hosted by blockchain as a service providers. This distributed ledger technology (DLT) redefines how we operate in the digital economy by establishing trust and security for all.
How does blockchain work?
Blockchain is a decentralized digital ledger system that records and verifies transactions and information across a network of computers called nodes. Its core components comprise decentralization, transparency, immutability, and automation.
If we break down the term blockchain, we get block and chain. So to understand how it works, imagine a chain of blocks, where each block represents a data set. These blocks are connected in a distinct order to create a continuous chain.
Each node maintains a copy of the entire blockchain to ensure that the information is consistent and not controlled by a single commodity. This means that once a block is added to the chain, it’s difficult for any single entity to manipulate the stored data without alerting everyone in the blockchain network.
This secure data distribution is possible through a hash, which is generated from a cryptographic hashing algorithm. Hash is a digital fingerprint unique to each block and ensures that any slight change in the block's data would result in a completely different hash.
Furthermore, to add a new block to the blockchain, its authenticity has to be validated via consensus. Consensus is a mechanism that ensures there are no discrepancies in the state of the distributed ledger. It’s essential in maintaining the integrity of the blockchain. Once consensus validates the block, it’s added permanently to the blockchain. This action is then distributed across all nodes to update their copies.
Now that we’re clear on how blockchain works, let’s dive deep into some of the applications of blockchain technology across different industries and sectors.
Blockchain applications in healthcare
By embracing blockchain solutions, healthcare providers can modernize operations, maintain data integrity, and enhance patient care. Blockchain doesn’t encounter privacy breaches like traditional methods, where the risk of unauthorized access exists. It also enables secure data interoperability in real time, reducing administrative inefficiencies.
Here’s a look into what blockchain applications in healthcare comprise.
1. Secure electronic health records (EHRs)
Medical professionals can't access complete patient history when patient data gets siloed. To overcome this problem, a blockchain-based system is linked to existing EHR software. The decentralized system stores and manages EHRs securely and provides a single view of a patient’s record. It also gives patients the freedom to approve changes to their EHRs, authorize who can view them, and control how they are shared by healthcare providers.
2. Clinical trial research
Clinical trials and continuous medical research are part of what takes a healthcare system to the next level. However, such initiatives are often burdened with data integrity issues. The blockchain serves as the single source of truth for research and trial data. It improves and secures record keeping and sharing while maintaining patient privacy.
Blockchain also asserts ethical checkpoints to ensure the trial is completed while staying compliant.

There are many ways through which blockchain solutions make asset management more advanced. It digitizes the portfolio and existing holdings for wider market access, liquidity, and ease of transfer. Blockchain also improves investor and stakeholder governance through customizable built-in privacy settings.
Blockchain applications in real estate
Businesses and professionals are becoming increasingly cognizant of blockchain applications in the real estate sector. It can transform property management and sales, optimize payments, and increase investment opportunities.
Here’s a look into the different uses of blockchain in real estate.
11. Fractional ownership and asset tokenization
Through blockchain, the process of real estate investment is repurposed, allowing investors to buy and sell fractional shares instead of pooling all their money to acquire property. Asset tokenization platforms built on blockchain let you create a digital token of ownership for real-world liquid assets. Once assets are tokenized, investors only need a trading app to execute borderless international trading.
12. Loan and mortgage security
Blockchain solves many challenges that come with paper documentation for loans and mortgages. Digitization of such documents provides access to critical information that supports future decisions like ownership rights and loan payment history.
By letting go of the paper system, blockchain serves as the single resource in the form of an immutable ledger system. It tracks and updates any changes in the database, including land titles, boundaries, and land use planning. The digitization of such processes eliminates any excessive administrative costs and prevents fraudulent transactions.
