Verifiable, tamper-proof post-quantum credentials
Earn a quantakrypto credential — for people and for organizations — that anyone can verify, that no one can forge, and that adds to your LinkedIn profile in one click. Each certificate is cryptographically sealed and timestamped on the Bitcoin blockchain with OpenTimestamps.
What you can earn
Complete the course and pass the exam to earn the individual Certified Post-Quantum Practitioner credential.
Finish a course to earn a completion credential for the skills you've built — verifiable and shareable.
Organizations that pass a quantakrypto audit hold an audit certificate — issued to the company, with expiry.
How it works
From enrolment to a credential you can prove — four steps, and the last one is where most certificates fall short.
- Enroll — create a free account (people) or connect your organization.
- Learn & prove — complete the course and pass the exam, or pass an audit.
- Earn — a credential is issued to you, hashed and timestamped for tamper-evidence.
- Share & verify — add it to LinkedIn, share the public verification link, or embed the badge.
Sealed and timestamped with OpenTimestamps
A certificate you can’t independently verify is just a claim. Anyone can screenshot a PDF, change a name, or invent a credential. We make ours provable instead — using OpenTimestamps, an open standard for anchoring data to the Bitcoin blockchain.
When a credential is issued, we compute a SHA-256 hash of its exact contents — the holder, title, issuer, and dates. That hash is submitted to the OpenTimestamps calendars, which batch it into a transaction recorded in Bitcoin’s blockchain. The result is a small, portable proof that this precise credential existed at that moment and has not changed since.
Because the anchor is a public blockchain rather than our own database, the proof does not depend on trusting quantakrypto — or on quantakrypto still existing. It is the same principle used to prove the integrity of legal documents and software releases, applied to your credential.
Change one character of the certificate and its hash no longer matches the proof. That mismatch is what makes forgery detectable by anyone, forever.
What this gives you
- Independent verification — anyone can confirm the credential existed and is unchanged, without trusting quantakrypto.
- Tamper-evidence — altering a single character of the certificate breaks its hash, and the mismatch is obvious.
- Longevity — the proof lives in Bitcoin's history; it stays verifiable even if quantakrypto is not around to vouch for it.
- No trusted third party — the timestamp is anchored in a public blockchain, not a private database.
Add to LinkedIn in one click
Every credential carries an Add to LinkedIn profile button that pre-fills LinkedIn’s certification form — name, issuer, issue and expiry dates, credential ID, and the public verification URL — so it lands in your Licenses & Certifications with a link recruiters can check.
Public verification & badges
Each credential has a public page at quantakrypto.com/credential/<id> with its status, dates, and integrity hash, plus a downloadable, embeddable SVG badge for your site or email signature.
Frequently asked questions
How do I earn a credential?
Individuals enroll (free), complete a course, and pass the exam to earn the Certified Post-Quantum Practitioner credential — or earn a completion credential for finishing a course. Organizations earn an audit certificate by passing a quantakrypto audit. All three produce the same kind of verifiable, tamper-proof credential.
Is enrolling free?
Creating an account and enrolling is free. Individual courses and certification exams are purchased per course; organization audits are a separate engagement. You only pay for the course or audit itself.
What is OpenTimestamps, and why does it matter?
OpenTimestamps is an open standard for proving that a piece of data existed at a certain time, by anchoring a hash of it into the Bitcoin blockchain. We hash each credential and timestamp that hash, so anyone can prove the certificate is authentic and unaltered — independently of us, permanently, with no trusted third party. A certificate you can't independently verify is just a claim; this makes it a proof.
Can I add my credential to LinkedIn?
Yes — one click. Every credential has an 'Add to LinkedIn profile' button that pre-fills LinkedIn's certification form with the name, issuer, issue and expiry dates, the credential ID, and the public verification URL. It appears in your Licenses & Certifications section.
How does someone else verify my credential?
Every credential has a public page at quantakrypto.com/credential/<id> showing its status, holder, dates, and the SHA-256 integrity hash. Anyone can open it to confirm the credential is genuine and unaltered. There's also a downloadable, embeddable badge.
Do credentials expire?
They can. Certifications typically carry an expiry date so the credential reflects current knowledge and standards; the expiry is shown on the verification page and carried into LinkedIn. Some completion credentials have no expiry.
Can organizations hold credentials?
Yes. Credentials can be held by a person or by an organization, and an organization's dashboard shows both its own certifications and those of its members. Organizations can also embed a 'Certified / Quantum-ready' badge that links back to their verification page.
