Blockchain

Primary definition

Blockchain technology enhances cybersecurity by replacing centralized systems with a decentralized, immutable, and cryptographically secure ledger. It reduces single points of failure, secures IoT networks, and provides transparent data integrity. Key benefits include improved authentication, tamper-proof storage, and reduced fraud, though it faces risks from 51% attacks and node-level hacking.
