Issue with proof
Certificates are encrypted, hashed and written to an immutable ledger at the moment of issue.
No jargon required. Here's exactly how hashing, blockchain anchoring and instant verification work together to turn a certificate into permanent, portable proof.
Instead of trusting a piece of paper — or a database that someone could quietly edit — iCertiX gives every certificate a mathematical fingerprint and records it where no one can change it.
Certificates are encrypted, hashed and written to an immutable ledger at the moment of issue.
Anyone can confirm a certificate from the ledger by scanning its QR code or opening its link.
Institutions manage their balance, batches and issuance from one secure dashboard.
When a certificate is issued, iCertiX runs it through a cryptographic function called SHA-256. This turns the entire file into a fixed 64-character code — its unique fingerprint.
No two different files produce the same hash.
You can't reconstruct the certificate from the hash — so no personal data is exposed.
Change one pixel, comma or date and the hash changes completely — instantly exposing tampering.

The hash is written into a block on a distributed ledger. Each block is cryptographically linked to the one before it, and copies live across many independent nodes.
To alter a single record, someone would have to rewrite every block after it — on the majority of computers in the network, simultaneously. In practice, that's impossible. The record is set in stone, with a trusted timestamp that proves exactly when it was issued.
Privacy stays intact: only the hash is anchored — never the student's file, name or personal data. The chain proves authenticity without ever exposing what's inside.
A verifier doesn't need an account, a login, or any blockchain knowledge. They scan or click — and the platform does the maths.
Scan the certificate's QR or open its verification link.
The presented certificate is fingerprinted again in real time.
The new hash is compared against the one anchored on-chain.
Match → genuine. Any difference → flagged invalid.
A scalable, multi-tenant platform engineered for institutions that issue at volume.
Isolated, secure workspaces per organisation.
Certificates and templates stored encrypted at rest.
Certificates generated as high-fidelity PDFs.
Issue and verify programmatically from your systems.
Bulk delivery with per-recipient status tracking.
Every action logged and tamper-evident.
No. Only the certificate's cryptographic hash is anchored on-chain — a one-way fingerprint that reveals nothing about the file or the person. The certificate itself stays in secure, encrypted storage. This is what lets iCertiX prove authenticity while staying aligned with GDPR and DPDP.
Any change — even a single character or pixel — produces a completely different hash. When the altered file is verified, its new fingerprint won't match the one anchored on the ledger, and it is immediately flagged as invalid.
Never. Employers, universities, embassies and government bodies simply scan the QR code or open the verification link. The check happens instantly in the browser — no login, no software, no crypto knowledge required.
No. iCertiX offers both cloud-verifiable and blockchain-anchored issuance. You can issue everyday certificates with SHA-256 hashing and live verification pages, and reserve on-chain anchoring for your highest-trust credentials — or apply it to everything. The choice is yours.
Yes. Once a hash is anchored, the record is permanent. A credential issued today remains independently verifiable for its entire life — with a trusted timestamp proving exactly when it was issued.
We'll walk you through the whole flow — from designing a template to anchoring a certificate on the blockchain and verifying it live.
