Cybersecurity is the practice of protecting systems, networks, and programs from online threats. Typically, the goals of these cyberattacks are to disrupt regular corporate operations, get, change, or delete sensitive data, or use ransomware to demand money from customers.

Blockchain technology gives a solution to enhance cybersecurity. Blockchain gives a privacy concept as an overlay network to improve data security. It uses cryptographic hashes and runs it on permissionless, distributed and public network architecture for strong data verification.

The characteristics of this privacy model guarantee the integrity, reliability, and transparency of data, creating a secure digital environment that makes data manipulation impossible and increases confidence of the people in digital records.

The architecture of blockchain is made in such a way that it protects data integrity. Every transaction added to a block then sealed and verified by a consensus process. This makes audit procedures much easier and increases confidence in the system’s dependability.

The use of cryptographic hash functions is a key component of the security framework of blockchain. These functions convert data into unique, fixed-size hash values, ensuring that even a small change in the data generates an entirely new hash. Because of this sensitivity to changes in the data, it is very difficult for attackers to alter the information without being detected.
