- Security: Cryptography ensures the integrity and security of the data.
Key Use Cases
Blockchain’s unique strengths make it suitable for a variety of applications:
- Payments: Facilitating secure and fast money transfers, especially for international payments.
- Supply Chain Management: Tracking goods and materials from origin to consumer, ensuring transparency and authenticity.
- Healthcare: Securely storing and sharing medical records, improving patient privacy and data interoperability.
