What is a Verifiable Credential?

A W3C Verifiable Credential is a cryptographically signed digital certificate. Anyone can verify it instantly, anywhere in the world, without contacting the issuing institution. The signature proves authenticity; a blockchain anchor proves the credential has not been tampered with.

Is the platform compliant with Indian regulations?

Yes. The platform is compliant with NEP 2020, UGC, NAAC and AICTE guidelines, and is integrated with DigiLocker, the National Academic Depository (NAD) and Academic Bank of Credits (ABC). It is also designed to comply with the DPDP Act 2023.

How fast is verification?

Under two seconds from QR scan to a green VALID badge. Verification runs at the institution's white-labelled portal, using the institution's own DID.

Can we host it on-premise?

Yes. The platform deploys either as a managed SaaS in our ISO 27001 / SOC 2-certified India-resident cloud, or fully on-premise across six servers in your own data centre. Both models produce identical W3C Verifiable Credentials.

What about historical certificates?

We provide a structured legacy migration pathway for both digital records (10K–50K credentials per day) and physical documents (500–800 records per team per day with OCR + Maker–Checker review).

How is pricing structured?

Pricing is custom and depends on institution size, credential volume, deployment model (SaaS or on-premise), and legacy-migration scope. Reach out via the lead form below for a quote tailored to your institution.

Verifiable Credentials for Universities & Colleges | Tamper-Proof Digital Diplomas

The Problem

Academic credentials are broken.

Academic credentials are among the most frequently forged documents in India. Employers spend weeks verifying degrees. Students carry paper certificates that can be lost or forged. NEP 2020, UGC and NAAC mandate a shift institutions now need to fulfil.

×

Credential Fraud

Forgeries are undetectable without calling the institution directly.

×

Manual Verification

Weeks of email and phone follow-up to verify a single degree.

×

No Audit Trail

No record of who verified what, or when — institutions are blind.

×

Compliance Gap

DigiLocker and NAD upload still relies on manual processes.

×

No Digital Records

Historical paper-only archives have no verifiable digital form.

The Platform

Three promises. One platform.

01

Issue Once.

Every certificate is cryptographically signed and delivered to the student’s digital wallet — instantly.

02

Verify Forever.

Any employer, anywhere in the world, verifies a credential in under two seconds — by scanning a QR code.

03

Comply Fully.

Built on W3C VCs. Integrated with DigiLocker, NAD and ABC. UGC, NAAC, AICTE and DPDP Act 2023 compliant by design.

Platform Overview

From ERP data to verified credential.

The solution lets institutions issue, manage and deliver tamper-proof digital certificates — anchored on the Polygon or Ethereum blockchain and delivered to every student’s wallet.

What you get

White-labelled verification portal at the institution’s own domain

Governed Issuance

Maker · Checker · Approver.

Every credential passes through a mandatory three-stage governed workflow before reaching a student. No certificate is issued without all three stages.

Import & Validate

Data In

Records imported from ERP/MIS via REST API or CSV. Validated for completeness, duplicates and schema compliance.

Make

Draft

Maker maps student data to templates, previews the rendered PDF and submits the batch for independent review.

Check

Verify

Checker independently verifies field-by-field against source records. Cannot be the same person as the Maker.

Approve & Issue

Sign & Anchor

Registrar gives final sign-off. VC cryptographically signed, blockchain hash committed, PDF generated, credential delivered.

On approval Credential signed (ECDSA) · Hash anchored on Polygon · PDF generated · Wallet delivered · DigiLocker pushed

Verification Flow

Verified in under 2 seconds.

Once a verifier is onboarded, every check runs at the institution’s white-labelled portal — no external service, no third-party trust required.

01
Scan QR Code
Any smartphone camera. The institution’s portal loads at its own domain.
02
Resolve DID
The platform fetches the institution’s public key from the Polygon ERC-1056 registry.
03
Verify Signature
VC signature checked against public key. Any alteration is detected immediately.
04
Check Revocation
Registry checked in real time — credential is ACTIVE or REVOKED with timestamp.
05

Deployment

SaaS or on-premise. Same platform.

Fastest path

SaaS — managed by Edulab

Hosted on ISO 27001 / SOC 2-certified cloud infrastructure in India. All student data stays in India, encrypted at rest.

No servers to procure. Recommended for the pilot phase — live within days of providing SSL credentials, SMTP and ERP access.

Live in days, not months
No infrastructure overhead
Continuous platform updates
India-resident data, encrypted at rest

Maximum sovereignty

On-Premise — institution’s data centre

Deploys across six servers within the institution’s own data centre. All student PII stays physically on campus — never leaving the institution’s network.

Edulab manages the application layer remotely; institution IT manages infrastructure.

Blockchain Architecture

Two deployment models. Same W3C output.

Both options produce identical W3C Verifiable Credentials. Choose based on your data governance and infrastructure policy.

Option A · Public

Polygon Mainnet

Public Ethereum-compatible L2

Best for: Fast go-live · no infrastructure overhead · global public auditability
DID method: did:ethr:matic — resolved from Polygon ERC-1056 registry
Gas cost: Less than ₹500 per year for full institutional volume
Auditability: Every transaction visible on polygonscan.com

Option B · Private

Private Ethereum

Institution-controlled Ethereum-compatible blockchain network

Best for: University-owned blockchain · data sovereignty · internal governance
DID method: did:web — resolved from institution’s own HTTPS domain
Gas cost: Zero — private permissioned network, no cryptocurrency
Auditability: Internal blockchain explorer / dashboard for authorised university administrators and auditors

Both produce identical W3C VCs · Both fully satisfy blockchain requirements · The institution chooses.

Legacy Migration

Bring every past student forward.

A structured, governed pathway to digitise historical academic records — degrees, marksheets, diplomas and certificates — as W3C Verifiable Credentials.

Track A

Digital Records

Records in ERP, database or Excel/CSV are exported, cleansed and mapped to credential templates. Processed in bulk through Maker–Checker–Approver.

10K–50Kcredentials per day

Export from source
Cleanse & deduplicate
Map to templates
Bulk MCA workflow

Track B

Physical Documents

Scanned at 300 DPI. OCR extracts fields with confidence scoring. Maker adjudicates scan vs. OCR in split-screen. Checker and Approver verify independently.
