IoT Oracle Security Audit FAQs
Technical answers to common questions about securing your sensor data feed integration with blockchain oracles.
We employ a three-phase methodology: 1) Architecture Review of data flow, sensor hardware, and oracle node logic. 2) Smart Contract & Off-Chain Code Audit using static analysis, manual review, and custom fuzzing for edge cases. 3) Integration & Latency Testing simulating real-world conditions and attack vectors like data spoofing or node failure. Our process is based on OWASP IoT Top 10 and blockchain oracle security best practices.
