Proof-first, not promise-first.
The classifieds model runs on vibes. Mobidata runs on cryptographic evidence, strict KYC, and a chain of custody that holds up in audit.
Cryptographic provenance
Every photo and consent video is hashed on-device, re-hashed server-side, and RFC3161 timestamped. Buyers can verify the chain themselves.
KYC-backed seller trust
National ID front + back, nominee docs, and a selfie — captured offline-safe and encrypted at rest. Fraud gets filtered before it hits the marketplace.
Publish in one tap
Pick one hero photo plus four gallery shots, set a price, and go live. Intake media stays private; only what you choose is public.
From buy-in to live listing — in minutes.
Intake
Capture seller ID, device details, 10 condition photos, and a short consent video — offline-safe, on any phone.
Verify
Media is hashed on-device and re-verified on the server. Your staff reviews on the dashboard.
Publish
Pick 1 hero + 4 gallery photos, set a price, and go live on the public marketplace.

Evidence integrity is not a feature. It’s the foundation.
Consent video and KYC media are legal evidence. That’s why we built durability in from day one — not bolted on after the first dispute.
End-to-end SHA-256
Client & server hashes must match — or upload fails.
Private by default
Intake media never appears in a public API response.
RFC3161 timestamped
Consent video gets a third-party trust anchor.
Audit on every read
Signed-URL issuance is logged with actor + IP.
RBAC matrix
Data-entry ≠ verifier ≠ owner. Least privilege by role.
DR-mirrored storage
Every private object replicated and size-verified.

Questions, answered.
How is Mobidata different from a classified listing site?
Every device is backed by seller KYC and a tamper-evident media chain before it can be listed. Listings are a view on top of verified intake — not a free-text posting.
What data is public vs private?
Only the phone photos you publish and a minimal device summary. IDs, nominee docs, selfies, and consent video are strictly private and audit-logged on every access.
Does it work offline?
Yes — the Flutter intake app captures, hashes, and queues everything offline. It uploads when the network returns, with no data loss.
How are disputes handled?
Each device has an immutable audit trail: consent video, signed media hashes, and a chain-of-custody log. Moderators can review on request.
