How Blockchain Benefits Healthcare System

Digital health records contain critical information about patients’ health, which can be used in harmful ways; therefore, protecting them from being breached is essential. Now some organizations are turning to blockchain technology to safeguard sensitive health data.

How does Blockchain work?
Blockchain is a decentralized digital ledger that records and encrypts transactions across a network. Each data is encrypted and linked in a chain making it more secure. Some advantages of this structure are as follows:
1- Decentralization
It means nodes are distributed to confuse attackers because there is no single point of attack.
2- Immutability
Once records are entered they cannot be altered. This ensures data integrity.
3- Encryption
Data is encrypted and can only be accessed by authorized persons.

How Blockchain Benefits in Healthcare
1- Enhance Security
Blockchain security with its cryptographic technique makes it almost impossible to hack and if someone does get unauthorized access then all other nodes will remain safe.
2- Patient’s Trust
Patients can view their data, revoke access, and share their details accordingly, which empowers patients to trust.
3- Standard Regulatory
Blockchain is transparent and it’s highly regulated to meet strict privacy guidelines like HIPAA and GDPR.

Use Cases of Blockchain in Healthcare
1- EHRs
Electronic Health Records that follow patients across the globe making sure not to duplicate data or have errors.
2- Testing
Blockchain goes under rigorous testing before being implemented in the healthcare system, thus promoting its integrity and reliability.
3- Supply Chain
Blockchain also manages the supply chain. Tracking pharmaceuticals from manufacturers to the patients, ensuring zero counterfeit drugs.

“Blockchain isn’t just about protecting data-it’s about empowering patients and enabling a more transparent, trustworthy healthcare system”
Dr. Lisa Taylor, a digital health expert

Blockchain is redefining the healthcare system with its robust data security. Some challenges need working like its expense in integrating with legacy systems etc. But with each day it’s improving from a market of $1.1 billion in 2021 to $5.7 billion in 2025 it’s accelerating its impact.
