Built for Construction Truth
Four modules that work together to create an unbreakable chain of verification from the moment evidence is captured.
Evidence Capture
GPS-stamped proof in one tap
Every photo is automatically tagged with GPS coordinates, UTC timestamp, and device metadata. No manual input required.
- check_circleAuto GPS geotagging on every capture
- check_circleUTC timestamp with millisecond precision
- check_circleDevice fingerprint and sensor metadata
- check_circleOffline capture with deferred verification
Cryptographic Hashing
Tamper-proof from the first byte
SHA-256 hashing creates a unique digital fingerprint for every piece of evidence. Any modification breaks the chain.
- check_circleSHA-256 asset hashing on capture
- check_circleChain-of-custody verification
- check_circleTamper detection with hash comparison
- check_circleMulti-file batch hashing support
Verification Engine
Compliance in 2.4 milliseconds
Automated compliance checking against project specifications, building codes, and contractual requirements.
- check_circleASTM/CSA compliance verification
- check_circleBlueprint spec matching
- check_circleMaterial grade validation
- check_circleAutomated pass/fail with audit notes
Immutable Ledger
Once sealed, forever proven
Verified records are sealed into an immutable ledger. No edits, no deletions — permanent proof of what happened on site.
- check_circleAppend-only immutable records
- check_circleZero-knowledge identity protocol
- check_circleAES-256 metadata encryption
- check_circleCross-node replication for redundancy
Connected to Your Workflow
The Proof plugs directly into your existing RenoNext apps — no extra setup required.
