Technical Implementation
Key Features
- Camera capture or gallery photo selection
- 4 difficulty levels: Easy (3x3) to Expert (6x6)
- Real-time puzzle status via Firestore listeners
- Push notifications when a puzzle arrives (FCM)
- Username-based contacts system
- Solve time and move count tracking
- Save solved images to device gallery
- Firebase App Check for API security

Anti-scam ERC-20 with escrow-by-default transfers and Kleros dispute resolution.
Indemnity (INDN)
An ERC-20 token where ordinary transfers are held in on-chain escrow for 7 days instead of settling instantly. During that window the payer can open a dispute and a decentralized Kleros jury decides who receives the funds. DEX swaps settle instantly via an owner-managed exemption allowlist.
Technical Implementation
Key Features
- Escrow-by-default transfers with 7-day dispute window
- Kleros decentralized jury for dispute resolution
- DEX exemption allowlist for instant swaps
- Stuck-dispute escape hatch (180-day timeout)
On-device IoT network anomaly detection. Mamba-2 forecaster, Zeek conn.log, no cloud.
Vigilo
An open-source research prototype that learns normal device behavior from Zeek connection logs and flags anomalies as forecast error. Detects port scans, DDoS, and noisy botnet traffic on consumer CPU hardware with no cloud dependency.
Technical Implementation
Key Features
- 5-minute behavioral windows per device (15 features)
- 75% detection at 1% FPR on IoT-23 (20 malware families)
- Runs entirely on CPU — no GPU or cloud required
- SPAN/mirror, gateway Zeek, or lab capture workflows
