Blockchain in Healthcare: Pros & Cons 2025
Blockchain technology has gained significant attention in recent years due to its potential to revolutionize many industries.
At its core, blockchain is a distributed ledger system that enables secure and transparent transactions without the need for intermediaries. While blockchain is often associated with cryptocurrencies like Bitcoin, its potential applications extend far beyond finance.
In this article, we will explore what blockchain is, how it works, and its potential applications.
What is Blockchain?
Blockchain is a distributed ledger system that enables secure and transparent transactions without the need for intermediaries.
A blockchain is a decentralized database that is maintained by a network of computers rather than a single entity.
Each block in the chain contains a record of transactions, and once a block is added to the chain, it cannot be altered or deleted. This makes blockchain an immutable and tamper-proof ledger.
How does Blockchain work?
Blockchain is a digital ledger technology that is based on a decentralized network of computers. It is essentially a database that is shared and maintained by a network of users, with no central authority controlling the data.
The basic principle behind blockchain is that every user on the network has a copy of the ledger, which they can add new information to. Once information is added to the blockchain, it cannot be deleted or modified, making it an immutable record of transactions.
Here is a simplified explanation of how blockchain works:
Transactions: Whenever a transaction is made on the blockchain, it is broadcast to the entire network of users.
Verification: The network of users then verifies the transaction to ensure that it is valid. This is done through a process called consensus, which can vary depending on the specific blockchain protocol being used.
Adding the Block: Once the transaction is verified, it is added to a block of transactions. Each block contains a unique code, known as a “hash,” which is generated based on the contents of the block.
Linking Blocks: The block is then added to the chain of previous blocks, with each block linked to the one before it through its hash code. This creates a secure and unalterable record of all transactions on the blockchain.
Network Maintenance: The blockchain network is maintained by a group of users, known as “nodes,” who perform tasks such as verifying transactions and maintaining copies of the ledger.
Decentralized Control: Since the blockchain ledger is shared and maintained by a decentralized network of users, there is no central authority controlling the data. This makes blockchain a trustless system, where transactions can be verified and executed without the need for intermediaries.
Potential Applications of Blockchain:
Finance: The most well-known application of blockchain technology is in the finance industry. Cryptocurrencies like Bitcoin and Ethereum use blockchain technology to enable secure and transparent transactions without the need for intermediaries.
Supply Chain Management: Blockchain technology can be used to track products throughout the supply chain, providing a transparent and auditable record of their journey. This can help reduce fraud, counterfeiting, and improve the efficiency of supply chain management.

By providing a secure and decentralized platform for sharing patient data, blockchain can improve the quality of care and reduce administrative burden on healthcare providers.
Identity Verification: Blockchain technology can be used to create secure and decentralized identity verification systems. By using cryptographic algorithms to verify identities, blockchain can eliminate the need for centralized identity verification systems, which are often vulnerable to fraud and hacking.
Real Estate: Blockchain technology can be used to streamline the process of buying and selling real estate by providing a transparent and auditable record of ownership and transfer. This can reduce the time and cost associated with traditional real estate transactions.
Blockchain technology has a wide range of uses, and it has the potential to revolutionize many different industries. Some of the most common uses of blockchain technology include:
