Security-Enhanced Blockchain Architecture

TITLE	Security-Enhanced Blockchain Architecture
ABSTRACT	This paper presents a security-enhanced blockchain architecture designed to mitigate critical vulnerabilities found in both traditional digital systems and existing blockchain frameworks. The proposed model introduces a multi-layered design that integrates advanced cryptographic safeguards, consensus-driven validation mechanisms, and automated smart contract functionalities to create a resilient, tamper-proof, and efficient system. The core innovations include the integration of a decentralized Public Key Infrastructure (PKI) to eliminate single points of failure, a Real-Time Anomaly Detection Engine for proactive threat mitigation, and a modular design that ensures network scalability and interoperability. The effectiveness and practical relevance of this architecture are confirmed by conceptual implementations in two high-impact sectors: healthcare record management and cryptocurrency transaction ledgers. These use cases demonstrate the system's capability to securely manage sensitive data while enabling trustless, automated transactions within a distributed environment.
