OraSRS: A Compliant and Lightweight Decentralized Threat Intelligence Protocol with Time-Bounded Risk Enforcement

Abstract

I present OraSRS, a protocol security and compliance engineering framework that addresses a fundamental tension in security systems: the trade-off between response speed and decentralized trust. Rather than focusing on blockchain as a core innovation, OraSRS leverages blockchain as an infrastructure layer to coor dinate trust in a protocol-safe manner while prioritizing ¡100ms response for real time defense. After implementing and testing several centralized and decentralized approaches, I observed that existing solutions inadequately balance speed, compli ance, and security. OraSRS achieves sub-100ms local response through optimistic execution at the edge while maintaining global consistency via protocol-based co ordination. Key innovations include: (1) a T0-T3 verification lifecycle decoupling local defense from final confirmation; (2) a commit-reveal protocol with economic incentives deterring Sybil attacks; (3) time-bounded risk enforcement ensuring reg ulatory compliance. Unlike pure blockchain protocols, OraSRS emphasizes protocol engineering for real-world deployability and compliance. Evaluation demonstrates sub-0.04ms local latency, 95.5% F1-score, and ¿95% Sybil defense rate. The sys tem is open-sourced at https://github.com/srs-protocol/OraSRS-protocol/ under Apache 2.0.
