Blockchain-based degreecertificates, explained.

How blockchain-anchored degrees work, why a signed PDF is no longer enough, and how India's NAD, ABC, and DigiLocker infrastructure pairs with W3C Verifiable Credentials to make every Indian degree instantly verifiable — for life.

Verify a degree nowFor universities

Why this matters in India, specifically

50+ million credentials issued every year

India is one of the largest credentialling markets in the world. The volume alone makes manual verification economically irrational.

0.5–2% fake-degree rate in CV samples

Industry studies place credential discrepancy rates in Indian CV samples between 0.5% and 2%. At a national hiring scale of millions of offers, that translates to tens of thousands of fraudulent credentials in the workforce — every year.

NEP 2020 and ABC are forcing the move

The Academic Bank of Credits requires per-course credit transactions to be machine-readable. PDFs cannot satisfy this requirement; verifiable credentials can.

DigiLocker and NAD are already digital

Indians already trust government-issued documents in DigiLocker. Wrapping academic credentials in W3C Verifiable Credential format adds cryptographic verifiability on top of an infrastructure people use.

How it works

Issuance to verification, in four stages

The mechanics are simpler than the marketing makes them sound. Here's the entire flow without jargon.

1

Issuance

When examination results are declared, the university's registrar signs each credential with a cryptographic key. The signed credential — containing the student's name, programme, grade, and metadata — is anchored on a public blockchain. The student's wallet receives the credential.

2

Storage

The credential metadata is stored on IPFS — a content-addressed network where every file is identified by its cryptographic hash. The on-chain record references this hash; any modification to the metadata produces a different hash and is detectable.

3

Presentation

The student presents the credential by sharing a credential ID, a QR code, or a wallet-to-wallet exchange. The verifier doesn't need the student to be online for the verification to work — the chain holds the proof.

4

Verification

Anyone — employer, embassy, foreign university, BGV firm — can verify the credential against the blockchain in seconds. The verification confirms the issuer, the holder, and that the credential has not been altered or revoked.

Signed PDF vs blockchain credential

Both are digital. Only one is verifiable independently of the issuer's server, in seconds, anywhere in the world.

What this means for you

For students

Your degree should not require a 6-week wait at every job application. A blockchain-anchored credential lives in your wallet for life and verifies in 10 seconds — for jobs, foreign admissions, and visa applications. You own it, not the university server.

For universities

Issuing credentials on a public blockchain reduces verification overhead at the registrar's office (often 60–80% of certain query types vanish), accelerates alumni mobility, and provides audit-ready evidence for NAAC. The infrastructure is standards-driven — no proprietary lock-in.

For employers and HR teams

Stop calling registrars. Verify any blockchain-anchored degree in seconds via the public verifier or a JSON API. Layer it on top of existing BGV processes — for credentials issued on the network, your cost goes to zero and turnaround drops to seconds.

Common questions

What is a blockchain-based degree, exactly?+
It is a digital credential where the proof of authenticity is anchored on a public blockchain. The student's name, programme, grade, and issuance date are signed cryptographically by the issuing university. Anyone can verify the signature and confirm the credential is genuine — without contacting the university.
Is a blockchain degree legally valid in India?+
The W3C Verifiable Credential is a digital document signed by a recognised issuer; under the Information Technology Act, 2000 (with the 2008 amendment recognising digital signatures), digitally signed documents have the same legal weight as physical originals. Pairing the blockchain credential with NAD registration ensures it is also the regulator-recognised record.
Can a blockchain degree be forged?+
Mathematically, no. Once a credential is signed and anchored on-chain, any modification to the data produces a different cryptographic hash and the signature no longer matches. A forger would need the issuing university's private key — which never leaves the institution's secure key management system.
How does this differ from a digitally signed PDF?+
A signed PDF only proves the file has not changed since signing — and only if the verifier has the issuer's certificate. A blockchain credential adds public, decentralised verifiability: anyone, anywhere, can verify against the chain without trusting any specific server. The verification itself is cryptographically certain rather than dependent on certificate-authority chains.
What if the blockchain goes down?+
Public blockchains are operated by hundreds to thousands of independent nodes — they don't have a single point of failure. Brief slowdowns can happen on any chain; verification queries resume immediately on recovery. Anchored credentials remain on the chain permanently regardless.
Does this mean students need a crypto wallet?+
Not necessarily. Most platforms (including Gradify) issue credentials to a wallet that students access via standard authentication — email, phone, or DigiLocker — without needing to manage seed phrases. The blockchain operates underneath; the student experience is closer to a banking app than a crypto wallet.
How much does it cost the university?+
On a high-throughput chain like Solana, the on-chain anchoring cost is sub-paisa per credential. The actual cost to a university is the infrastructure platform fee, which scales with enrolment and integrations. See the pricing page for tier details.
Can old, paper-based degrees be migrated?+
Yes, retroactively. Universities routinely back-load 5–10 years of historical credentials when adopting blockchain infrastructure. The original issuance date is preserved in the credential metadata; alumni gain instant verifiability for older degrees.
