Open Badges 3.0,
signed by your organization
Geduk issues digital badges on the 1EdTech Open Badges 3.0 standard. Every badge is signed by the organization that issues it. Anyone can verify it, even outside the platform: a recruiter, a funder, another tool. The recipient adds it to LinkedIn or keeps it in a badge wallet. Badges are included in every Geduk LMS subscription.
Why
An image can be copied,
a signed badge can be verified
A badge that is only an image proves nothing: anyone can redraw it. An Open Badge 3.0 carries what it stands for: who issued it, for what, against which criteria, until when. And a signature no one can produce without your organization's key.
The principle: every badge is a digital credential in the W3C Verifiable Credentials 2.0 format, signed by your organization (VC-JWT, RS256). Any Open Badges 3.0 verifier checks the signature with the organization's public key. Whoever checks needs no account, and does not have to write to you.
Checked with the official 1EdTech verifier. Badges issued by Geduk pass the 1EdTech Open Badges 3.0 verifier (vc.1ed.tech): 14 tests, no errors, no warnings.
For the issuer
Create a badge,
then award it
-
1
Present your organization
The organization that issues the badges has a public profile. Its name is what the verifier sees, and its key signs every badge.
-
2
Describe the badge
A name, a description, the criteria, a square image, a type, a validity period and a short code. You can also align it with the frameworks it targets: ESCO, or the French RNCP and RS registers.
The AI proposes all of it from a training or a few sentences, image included: the platform composes the badge (shape, colour, icon, label) and you adjust it before saving. You can also upload your own image.

Publish, then award
Once published, the badge goes to the people who earned it: one at a time, or a whole class at once.
One by one or as a group
You pick the person, you award. Or you tick the learners enrolled in a session, and they all receive it at once.
By CSV or XLSX import
A whole class at once, from a file.
By API or AI assistant
Your tool awards badges through the API. Or you ask your AI assistant, through the MCP server.
Automatically, with the LMS
Placed on a program or a module, the badge goes to every learner who completes it (or passes it), in all its sessions, with no manual step.
No account needed
Reward training
Geduk does not host
Classroom training, a partner's course, another tool: the badge does not require the training to have taken place in Geduk. It can be awarded to a plain email address. The person has no account to create: they get an email with the link to their badge.
The email address is never written in plain text in the badge. It only holds a salted hash: enough to tie the badge to the person without exposing their address to those who view it.

Day to day
Revoke with a reason,
let it expire
| Situation | What you do | What the public page says |
|---|---|---|
| valid | You award the badge: the person receives their link | Valid, with the criteria and the evidence |
| awarded by mistake | You revoke it with a reason, and email the person if you wish | Revoked, with the reason |
| period over | Nothing: the badge reaches the end of its validity period | Expired |
| The revocation is also published in the status list: a verifier outside Geduk reads the same answer as the public page. | ||
Included in the LMS
Included in every plan,
with a yearly volume
Open Badges are part of the Geduk LMS: no add-on to buy, the free plan included. Each plan comes with a number of badges awarded per year, next to its users and its storage.
| Plan | Open Badges awarded per year |
|---|---|
| Discovery (free) | 100 |
| Essential | 1,000 |
| Pro | 5,000 |
| Growth | 20,000 |
| Network | 50,000 |
| The volume counts the badges awarded over the last 12 months across the whole space: by hand, by import, automatically or through the API. The counter frees up day after day. On a dedicated instance, the volume is set with you. | |
Badge or certificate? Both can be verified. The verifiable certificate (page in French) is a PDF with a QR code, to attach to a file. The badge is made to travel: on LinkedIn, in a badge wallet, in other tools. Plan prices are on the pricing page, and everything the LMS does is listed on the features page.
Frequently asked questions
Badges, plainly
A digital badge on the open Open Badges 3.0 standard from 1EdTech, built on W3C Verifiable Credentials 2.0. Every badge is a digital credential signed by the organization that issues it.
