What information is recorded through Hedera?

D-Certify uses Hedera for credential attestations and their transaction history. Credential metadata contains references to the corresponding IPFS content; the original document itself is not stored directly on Hedera.

Are original documents stored directly on Hedera?

No. Documents are stored through IPFS, with Pinata used by the project for IPFS storage. NFT metadata references the corresponding IPFS content, while Hedera records the credential attestation.

How can someone verify a credential?

Open the public Credential Verifier and use either a credential ID or document upload. The verifier checks the submitted credential data against its corresponding content and attestation references.

Can D-Certify support universities or hackathons?

Yes. The issuance flow is designed for organizations that award credentials, including universities, schools, hackathons, training providers, course platforms, and event organizers.

What happens if a credential file is changed?

IPFS uses content-addressed references, so changing a document produces a different content identifier. That difference gives the verifier a way to detect that the uploaded file does not match the referenced content.

Verifiable credential infrastructure

Credentials built to be trusted.

D-Certify helps organizations issue tamper-evident digital credentials that recipients can access and anyone can independently verify.

The credential gap

A document is only useful when it can be trusted.

Conventional credentials often leave the reviewer with a visual file but no dependable way to check where it came from or whether it changed.

D-Certify connects the document, its issuer, its recipient, and a traceable attestation—creating a practical verification path without claiming that technology alone can eliminate fraud.

Easy to alter

Traditional PDF certificates can be changed without leaving an obvious trace for the person reviewing them.

Difficult to verify

Employers and institutions often depend on slow, manual confirmation with the original issuer.

Locked in isolated systems

Recipients can lose a clear access path when an issuer changes platforms or moves its records.

Limited portability

Credentials are frequently hard to share and validate across organizations, tools, and borders.

The D-Certify approach

A clearer path from issuance to verification.

Tamper-evident records

Fast independent verification

Recipient-accessible credentials

Transparent issuance history

How it works

From issued document to verifiable record.

One connected flow gives each participant the context they need, while keeping the verification experience straightforward.

Issue

An authorized organization uploads a credential and assigns it to its recipient.

Anchor

Metadata references content stored through IPFS and the credential is attested through Hedera.

Receive

The recipient accesses the issued credential and confirms receipt in the recipient portal.

Verify

A third party checks the credential using its ID or by uploading the corresponding document.

D-Certify product suite

One credential. Three clear experiences.

Purpose-built portals give issuers, recipients, and reviewers the tools they need without mixing their workflows.

Each application opens in its own secure portal and can be accessed directly from this page.

Technology architecture

Verification without blind trust.

D-Certify combines an accessible application layer with content addressing and a distributed attestation record. Each technology has a focused role.

The issuer establishes the credential, the recipient receives access, and an independent verifier can compare the document with the record created during issuance.

Verification is based on credential data and its corresponding references rather than a visual badge alone.

Practical outcomes

Infrastructure that makes credentials more useful.

The value is not the blockchain label. It is a clearer, faster, and more portable way to establish credential context.

Built for real issuance and review workflows

Tamper evidence

Content references make silent document changes easier to detect during verification.

Faster verification

Reviewers can check a credential without beginning a manual email chain with its issuer.

Portable credentials

Recipients have a credential record they can access and present beyond one institution's workflow.

Clear ownership

Issuer, recipient, and credential details create a clearer chain of context for every record.

Transparent issuance

Hedera attestations provide a distributed record of credential transactions and history.

Reduced manual checks

A public verification path helps teams reserve human review for cases that need it.

Built for every side of the record

Issue with clarity. Receive with confidence.

Separate experiences keep each participant focused while the credential record connects the entire lifecycle.
