The healthcare industry, traditionally characterized by fragmented data, security vulnerabilities, and complex administrative processes, is ripe for a digital transformation.

Blockchain technology, the decentralized and immutable ledger system, is emerging as a powerful solution to these challenges. By creating a secure, transparent, and patient-centric ecosystem, blockchain has the potential to revolutionize how health data is managed, shared, and utilized.

How Blockchain Works in Healthcare
At its core, a blockchain is a chain of digital "blocks" of data, each secured with cryptography. When a new transaction or data point is created, it is verified by a network of computers (nodes) and added to a new block, which is then permanently linked to the previous block. This creates an unchangeable record of all transactions.

In healthcare, this technology can be applied to create a "single source of truth" for patient data. Rather than storing sensitive health records on the blockchain itself, which would be a privacy concern, a unique cryptographic hash of the data is stored. This hash acts as an immutable record of the data's existence and integrity, and patients can use private keys to grant and revoke access to their information.
