Blockchain, Cryptography, and Digital Privacy: A Deep Dive

Abstract

The rapid growth of digital technologies has intensified concerns about data privacy and security. Blockchain technology, combined with advanced cryptographic methods, presents a promising solution to enhance digital privacy by enabling decentralized, transparent, and tamper-resistant systems. This article explores the foundational principles of blockchain and cryptography, evaluates their interplay in preserving digital privacy, and examines current challenges and future directions. Through comprehensive analysis, the study highlights how cryptographic protocols such as zero-knowledge proofs and homomorphic encryption can significantly augment privacy on blockchain platforms, while addressing inherent scalability and usability challenges.
