Decentralized Structure of Blockchain and Data Security in Digital Financial Systems

In the digital financial ecosystem, data security has become a fundamental concern due to the growing need for privacy, integrity, and user control. The decentralized structure of blockchain technology is redefining how financial data are secured and managed, shifting from traditional centralized models to more resilient and transparent frameworks. This paper presents a systematic comparative analysis of blockchain-based security mechanisms in digital financial systems, emphasizing their role in mitigating risks such as fraud, data breaches, and unauthorized access. By examining key decentralized platforms and consensus mechanisms, including Proof of Work (PoW), Proof of Stake (PoS), and Byzantine Fault Tolerance (BFT), this study critically assesses their impact on financial data integrity and security. Furthermore, it explores the architectural advantages of decentralization, such as immutability, transparency, and cryptographic trust, in enhancing financial data protection. This research aims to provide a comprehensive understanding of how blockchain-driven decentralization fortifies financial systems against cyber threats, offering a robust alternative to traditional security paradigms. The findings contribute to the ongoing discourse on blockchain security and provide insights for future advancements in decentralized financial infrastructures.
