Chapter 1: Introduction
1.1 Background
The rapid growth of cryptocurrency has heightened concerns about transaction privacy. Traditional models expose user behavior to public tracking, risking personal data leaks. Privacy-enhancing technologies address these vulnerabilities and are increasingly integral to cryptocurrency ecosystems.
1.2 Significance
Cryptocurrencies thrive on decentralization, anonymity, and immutability—yet these features also invite privacy risks. Balancing these strengths with robust privacy safeguards is critical for sustainable adoption.
1.3 Research Objectives
This article systematically explores:
- Applications of privacy technologies in cryptocurrency.
- Their necessity and impact on ecosystem development.
- Current implementations and future trends.
1.4 Structure
Six chapters cover:
- Introduction
- Cryptocurrency Overview
