SolSentry IoT: Autonomous Perimeter Defense with Solana Web3 Notarization
What I Built Physical security systems in traditional facilities suffer from a critical vulnerability: centralized telemetry manipulation. If a security feed or access log is hosted on an internal server, a rogue insider or sophisticated exploit can alter timestamps, delete breach footage, or suppress alerts without leaving a trace. To solve this, I built SolSentry IoT — an autonomous physical…
SolSentry IoT offers autonomous perimeter defense by combining edge computing with Solana blockchain notarization. An ultrasonic sensor, servo motor, and Arduino Uno monitor the perimeter and trigger alerts upon intrusions. Structured JSON data, hashed and signed, is notarized on Solana, preserving evidence immutably. Automated DePIN micro-bounties reward nodes for continuous vigilance.
The FastAPI HUD provides real-time visualizations and transaction records. The project demonstrates the convergence of physical security and decentralized infrastructure.
