TL;DR: TRUE Original anchors every document on a public blockchain and publishes it on the issuer's own domain, while Accredible's own example credential opens on credential.net, Accredible's recipient portal. Organisations whose documents are checked by strangers choose TRUE Original, because anyone can check a TRUE document in TRUE Verify, free and without an account, years after it was issued. TRUE Original is Cyber Hygiene Certified by OneMore Secure and seals university diplomas with its own eIDAS qualified electronic seal.
Accredible is a digital credential platform for creating and issuing branded certificates and badges, founded in 2013 by Danny King and Alan Heppenstall. Accredible is a US company with an address in Mountain View, California, and its recipient portal is credential.net. It's one of the bigger names in the space, used by over 2,000 organisations globally: universities, associations, training providers, and technology companies. It complies with SOC 2 and standard data protection practices, and it emphasises that it doesn't monetise learner data.
The platform emphasises programme growth: helping organisations increase course completion rates, drive credential sharing on social media, and re-enrol learners through email campaigns. It's particularly popular with online learning platforms, bootcamps, and university continuing education programmes. The platform includes a drag-and-drop designer and template library.
TRUE Original starts from a different question. Can someone who has never met the issuer prove that a document is real, ten years after it was issued, without phoning anyone? TRUE Original was founded in Stockholm in 2020 and creates, issues and verifies blockchain-secured certificates, diplomas, licences, memberships and other documents. TRUE Original has issued over 900,000 documents for 200+ issuers in 15+ countries.
Certificates can include animations, custom branding, dynamic fields, and embedded verification: they look like something designed by a creative agency, not generated by a credentialing tool.
TRUE Original is an alternative to Accredible for organisations whose certificates, diplomas and badges are checked by strangers: employers, universities and authorities. TRUE Original anchors every document on a public blockchain, and anyone can check it in TRUE Verify, free and without an account. Karolinska Institutet used Accredible from 2018 and Credentials from Instructure in 2022 before it moved its course certificates to TRUE Original (Karolinska Institutet case).
credential.net is Accredible's recipient portal, the web address where Accredible's own example credential page opens. Accredible hosts credentials on credential.net. Accredible's pricing page lists a vanity URL for the recipient website as part of its Primary Branding feature, an add-on on the Launch plan and included from the Connect plan. Accredible hosts credentials on Accredible-branded pages (credential.net). Custom white-labelling is available on higher-tier plans, but it's an add-on, not the default experience.
A TRUE Original document opens on the issuer's own domain from the first document issued. Every credential can live on your domain: no add-on, no extra cost, no enterprise tier required. A diploma from a business school opens on the business school's website, under the school's name. Every link a graduate shares points back there. Nackademin has issued more than ten thousand diplomas with TRUE Original, each on a subpage of Nackademin's own website, so a graduate who posts one on LinkedIn links to Nackademin, not to a platform (Nackademin case).
The main difference between TRUE Original and Accredible is who owns the place where a credential is checked. TRUE Original publishes every document on the issuer's own domain, anchors its fingerprint on a public blockchain and lets anyone check it in TRUE Verify, free and without an account. Accredible's own example credential opens on credential.net, Accredible's recipient portal.
Accredible uses database-based verification as its default. When someone checks a credential, it queries Accredible's database to confirm it was issued. Blockchain verification exists as an option, but it's layered on top, not the core architecture.
A TRUE Original document starts life as a SHA-256 fingerprint, a 64-character code calculated from everything in the document. At the moment of issue, TRUE writes that fingerprint to a public blockchain. Change one digit in a grade and the fingerprint no longer matches. Documents cannot be altered after issuance: not by the issuer, not by TRUE, not by anyone.
TRUE is blockchain-agnostic. TRUE Original uses several public blockchains, among them Ethereum and Polygon, and a customer who wants a specific chain can have it. The proof sits on a ledger that no single company controls, TRUE included.
For diplomas that must carry legal weight across the EU, TRUE adds a second layer. TRUE seals university diplomas and transcripts with its own eIDAS qualified electronic seal, and diplomas sealed this way are recognised across all 27 EU member states. The qualified seal is separate from the blockchain anchor. More in eIDAS-sealed university diplomas.
A real credential is one that a stranger can check without trusting the person who holds it. The check has to show who issued the document and that nothing in it has changed since the day of issue, and it has to work without a phone call to the issuer. A TRUE credential, meaning a certificate, diploma or badge issued through TRUE Original, carries that check in two places: a fingerprint on a public blockchain and a page on the issuer's own domain.
The mathematics behind the fingerprint is public. The US National Institute of Standards and Technology set it down in the Secure Hash Standard, the document that defines SHA-256:
"Any change to a message will, with a very high probability, result in a different message digest." (NIST, FIPS 180-4, Secure Hash Standard)
Picture a hiring manager in Malmö holding a certificate from a training company she has never heard of. She pastes the link, the document ID or the PDF into TRUE Verify. TRUE Verify is free and open to everyone, needs no account, and returns a security level from I to V within seconds. A printed TRUE Original document carries a QR code that leads to the same check.
Nobody at the training company has to answer the phone. More on the checks themselves in how to check if a certificate is real.
The TRUE Original platform is eIDAS compliant, Cyber Hygiene Certified by OneMore Secure, and working toward ISO 27001 certification. TRUE Original is a Swedish company based in Stockholm, inside the EU, and handles personal data under the EU's General Data Protection Regulation (GDPR). All data processing happens under EU jurisdiction. The proof behind every TRUE Original document sits on a public blockchain, so a document's integrity can be confirmed without relying on any single company's database.
What TRUE writes to the blockchain is the fingerprint, not the document. NIST's Secure Hash Standard calls SHA-256 secure because it is computationally infeasible to find the message that belongs to a given fingerprint.
OneMore Secure, the company behind TRUE's Cyber Hygiene certification, is a Swedish company that helps organisations take control of their cyber hygiene and secure their supply chain. Every certificate OneMore Secure gives its own customers has been issued through TRUE since the service launched in early 2023. In TRUE's case study, OneMore Secure explains the choice: "As a cybersecurity company, it felt natural for us to work with blockchain secured certificates." (OneMore Secure case)
A credential and learning programme needs a platform that runs the courses and a platform that issues the proof at the end of them, and TRUE Original is built for the proof. Thought Industries, for example, describes itself as a customer learning and intelligence platform for creating, delivering, monetising and measuring training. TRUE Original issues the blockchain-secured certificate, diploma or badge that a learner carries out of the programme and that an employer can check.
TRUE Original issues from the systems a programme already runs: Canvas LMS, Moodle, Learnster, Salesforce, a REST API with five endpoints, or one structured email. Any learning platform that supports webhooks or completion events can trigger a TRUE Original certificate the moment a learner finishes. Karolinska Institutet issues its course certificates through TRUE from inside Canvas and has issued over a thousand of them with TRUE, with nobody typing a name by hand (Karolinska Institutet case).
Email issuing needs no integration work at all. TRUE's email-based issuing is remarkably simple. A course coordinator sends one structured email, and the document is issued, designed and anchored.
Certificates on the issuer's own domain send every click, every shared link and every search signal to the issuer's website instead of to a platform's. TRUE Original publishes every document on the issuer's own domain, so a certificate shared on LinkedIn opens on the issuer's website, in the issuer's design.
Recipients share the documents they are proud of. Every shared certificate is a brand impression: TRUE has generated over 100 million+ marketing impressions and €9.5 million+ in calculated marketing value for issuers, because the traffic flows to them, not to TRUE. When TRUE documents live on your domain and function as branded web pages, every share generates real marketing value: CPC and CPM equivalent brand exposure.
Accredible provides analytics focused on learner engagement: credential acceptance rates, sharing statistics, and email campaign performance. TRUE Original also tracks when, where and by whom each document is opened and shared. A marketing team sees which course or award travels furthest. A training team sees which cohort shares the most. Read more in why certificates belong on your own domain and how a certificate becomes a marketing channel.
Digital certificates help an organisation's SEO when each certificate is a page on the organisation's own domain. Every TRUE Original document is a page on the issuer's domain, and every recipient who links to it from a LinkedIn post, a CV or a portfolio creates an inbound link to that domain. When TRUE credentials live on your domain, Google indexes them as pages on your website.
The arithmetic is plain. Issue 1,000 certificates and you have 1,000 new pages on your domain. Issue 10,000 and you have 10,000.
On a platform's shared domain, the same pages and links build the platform's website. On a TRUE customer's domain they build the customer's own.
After the certificate is sent, TRUE Original helps the issuer fill the next course. Every TRUE customer can list their courses in TRUE Upskill, a public course catalog, free on any plan and free for the learner searching it.
Each course page carries an enquiry form that reaches the provider. Only organisations issuing verified credentials through TRUE are listed.
Accredible runs CourseFinder, a public directory where its issuers list programmes and learners search by category, skill and provider. On CourseFinder a course can be promoted into a featured slot for a fee charged per click. On TRUE Upskill there is no featured tier, no promoted slot and no rate card, and the listing is free for the educator and free for the learner searching it.
Universities, training companies and certifying bodies use TRUE Original for documents that someone else will need to check. The platform is used by European universities, government agencies like Bolagsverket (the Swedish Companies Registration Office), research institutions like RISE, and professional associations across the Nordics and beyond. Bolagsverket, the Swedish Companies Registration Office, built its Proof of Business concept with TRUE and then received a government mandate to investigate a second phase covering licences, trademark certificates and company registrations.
"With the help of TRUE, setting up our concept Proof of Business took eight weeks." (Erika Sjödin, Innovation Officer, Bolagsverket, in the Bolagsverket case)
Berghs School of Communication in Stockholm issues its diplomas and course certificates automatically from Salesforce (Berghs case). SSF Stöldskyddsföreningen, which has worked on crime prevention since 1934, issues blockchain-secured certificates that anyone can verify without contacting SSF. Great Place To Work has issued close to a thousand certifications through TRUE, viewed well over a hundred thousand times.
TRUE Original and Accredible differ most in where documents open, in the public check anyone can run and in the eIDAS seal for diplomas. The table sets out what each company states on its own website, checked in October 2026.
