Blockchain in cybersecurity offers enhanced protection against cyber threats by providing an immutable and decentralized ledger for data verification. It secures sensitive information, ensures integrity, and helps prevent unauthorized access. Through cryptographic algorithms, blockchain technology eliminates the need for centralized control, making it harder for malicious actors to tamper with data. Its ability to trace, authenticate, and secure data transactions creates a robust system for preventing hacking, fraud, and data breaches in the cybersecurity landscape.
