I've posted my thoughts on this on the Moodle Tracker issue here.

The textual summary is the visual representation of the badge, but to have a valid open badge you would also need to respond to the assertion address that's embedded into the badge and checked by backpacks to ensure the badge is valid.

For the url provided above that would be:

https://moodle.org/badges/assertion.php?b=5fd502f859c0588b3d3348aedc2c008d55755376

If you visit that you'll see the information is encoded in a specific format. While I think it would be possible to keep around just the information without a real moodle site, it would certainly be more straightforward to keep the site if that's an option for you.

As far as I can see this is a limitation of badges. If you rely on the organisation to verify badges they need an active service running to validate against.

There is some interesting work going on to tie badge validation to the bitcoin blockchain which would allow validation to become decentralised:

But at this stage the technology is still at the experimental stage.

Hi Matias,

I'd suggest you ask your question here:

Or contact your Totara partner for assistance.

Yes I saw that, and you are right that something is going to have to be done before November to avoid things breaking.

According to this tweet:

There is a plan to migrate to a different authentication method for badges but until more details are known it is difficult to assess what this with involve on our side.
