Digital proof created — now tamper-proof
Your information is now permanently sealed on a public ledger. Any later change will be detected.
Technical details
All profile fields are canonicalized and keccak256-hashed into a code representing the profile “snapshot” at submission time. That code plus the block timestamp is written to the ledger. Because the hash is highly sensitive, any small change yields a completely different code, so a profile cannot be edited and still match the sealed snapshot.
How it works
- 1
Enter the profile
Name, national ID, credit score, proposed limit.
- 2
Freeze the state
The system snapshots the profile at that instant and seals the proof.
- 3
Verify later
Any change from the snapshot is detected.
The problem you face
- Credit profiles can be edited by insiders and backdated as if nothing changed.
- It is hard to prove the profile state at the exact moment a credit decision was made.
- Compliance and insider-fraud risks are hard to trace without an objective timestamp.
What you gain
- No backdating. The profile state is locked to the millisecond; the past cannot be edited.
- Defend credit decisions. Prove exactly what the profile looked like at approval.
- Audit-ready. Each profile snapshot is a timestamped proof, ready for inspection.
Real-world scenario
Credit assessment
At loan approval, an officer snapshots the profile with a credit score of 720 and a 300M limit. Six months later a default arises with suspicion the profile was “improved” afterwards. The sealed proof shows exactly what the profile was at approval — protecting both the bank and the honest officer.
Frequently asked questions
Is customer data safe?
Yes. Only the fingerprint is public; personal data never leaves your system.
What about legitimate updates?
You seal a new proof for the new version; the version history stays transparent.
Does this replace my current KYC system?
No. It adds a tamper-proof evidence layer on top of your existing system.
