ABSTRACT
The proliferation of ransomware attacks has emerged as a critical challenge in the cybersecurity domain, with traditional, centralized detection and response mechanisms often proving insufficient against sophisticated and rapidly evolving threats. This research proposes a blockchain-based framework designed to enhance ransomware detection and response by leveraging the inherent attributes of blockchain technology—immutability, decentralization, transparency, and traceability. By maintaining a tamper-resistant ledger of access logs and system events, the proposed system facilitates real-time anomaly detection and robust incident response capabilities without relying on third-party intermediaries. The framework promotes collaborative threat intelligence sharing and aligns with zero-trust principles, aiming to establish a more resilient and proactive security posture. Through a combination of theoretical modeling and critical analysis of existing solutions, this study highlights the transformative potential of blockchain in strengthening digital infrastructure against ransomware threats. The findings suggest that decentralized technologies can play a pivotal role in advancing next-generation cybersecurity strategies
