Four steps. One tamper-proof record.
From protocol definition to cryptographic proof—engineered for industrial compliance.
Step 1
Engineering Defines
Technical teams encode procedures as structured protocols—conditional logic, evidence requirements, timing constraints. Version controlled like software.
Step 2
App Enforces
Mobile app enforces protocol logic—conditional branching, time locks, evidence requirements. Cannot skip steps or modify in the field. Protocol runs as designed.
Step 3
Evidence Captured
Photos, sensor readings, timestamps, GPS coordinates. Every step collects forensic-grade evidence tied to the executing technician and protocol version.
Step 4
Cryptographically Sealed
Execution is cryptographically sealed and submitted. Immutable record of who did what, when, with what evidence—tamper-proof audit trail.
Step 01 - Protocol as Code
Industrial procedures as executable code
Structured protocols with conditional branching, evidence requirements per step, and app-enforced timers. Version controlled like software.

Step 02 — Execute
Technicians execute step by step
The field app guides technicians through the protocol in real-time. Evidence is captured as work happens—all timestamped, geolocated, and hashed.

Every execution follows the protocol
Whether it's production, assembly, commissioning, or field service—every execution follows the same defined protocol. No shortcuts, no skipped steps.

Enforced sequence
Auto-geotagged
Multi-modal capture
Ambient sensors captured too
Gyroscope, accelerometer, barometer, ambient light—all logged in the background. If someone's recording from a desk instead of the field, the sensors know.
Step 03 — Record
Forensic-grade evidence, captured automatically
Every piece of evidence is captured in context—tied to the specific step, the exact moment, and the precise location.

Step 04 — Seal & Replay
Immutable evidence. Complete replay.
When execution is complete, the record is cryptographically sealed. Anyone with access can replay exactly what happened—in sequence, with full context.
