BLOCKCHAIN-BASED DATA PROTECTION: EXPERIENCES IN USING MODERN CRYPTOGRAPHIC PROTOCOLS

Main Article Content
Abstract
This paper presents a hybrid blockchain–cryptography framework designed to ensure data privacy, integrity, and quantum-resilient security. By integrating Zero-Knowledge Proofs (ZKPs), Homomorphic Encryption (HE), Multi-Party Computation (MPC), and Post-Quantum Cryptography (PQC), the proposed model addresses emerging threats in decentralized environments. A comparative analysis of experimental results from 2019–2024 high-impact studies shows that hybrid architectures achieve an optimal balance between performance and security, with compliance to GDPR and HIPAA standards. The study concludes with future research directions, including hardware acceleration, interoperability, and quantum-adaptive consensus protocols[1].
