Securing Digital Assets in the Quantum Era: A Comprehensive Approach to Blockchain Wallet Security

Authors- Amratanshu

Abstract-This research addresses the growing need for enhanced security in blockchain wallets, focusing on emerging threats like quantum computing. It proposes a framework to future-proof wallets by integrating post-quantum cryptography (PQC), advanced biometric authentication, and decentralized security. With traditional cryptographic algorithms like RSA and ECC vulnerable to quantum decryption, PQC is essential for securing digital assets long-term. Additionally, biometric techniques, such as fingerprint and facial recognition, offer a robust defense against unauthorized access. The study also explores decentralized security by combining PQC with blockchain’s immutable ledger to resist quantum threats. Innovative solutions, such as zero-knowledge proofs (ZKPs) for privacy-preserving biometric authentication and advanced techniques like multi-signature and behavioral biometrics, are examined to strengthen wallet security. A decentralized biometric sharding approach is proposed to protect encrypted biometric data, while context-aware dynamic authentication adjusts security policies based on user behavior. A decentralized recovery system using threshold cryptography is introduced to tackle key recovery. Looking ahead, the paper explores the potential of emerging interfaces like holographic displays and brain-machine interface (BMI) authentication to improve wallet usability and security. This research outlines a comprehensive roadmap for the next generation of blockchain wallets, combining advanced security technologies, energy efficiency, and future-ready features for a seamless, secure digital asset management experience.
