I wanted a security system nobody could quietly argue with. The device sees it, and the chain remembers it.
- 01ESP32 firmware publishes sensor telemetry over MQTT (HiveMQ)
- 02PIR presence detection, surge detection with automatic cutoff, anomaly detection on readings
- 03Node/TypeScript + Express backend with Socket.io for live dashboards, Supabase/Postgres for state
- 04Solana (devnet) and Lisk (testnet) for verification; Phantom wallet auth; blockchain-verified PDF reports
- 05Voice commands gated behind confidence thresholds; Telegram and Firebase push alerts
- 06Property-based tests (20) alongside integration and unit coverage
Keeping one system coherent across four environments: firmware, cloud, chain and browser. Each one fails in its own way, and you have to learn all four.
