Unfortunately, I didn't have time to go deeper into the documentation on this topic.
You know what solution is best for you and I am asking you for support.
I don't want to create this badge system without knowing it.

The badge system is the admin's time spent on advertising (promoting) the project in the volunteer community :-)
Encourages members to earn more and more credits to achieve system-defined milestones and receive the next badge in their signature
In fact, this is just a beautiful, bright icon characteristic of this project (or a separate application)
More precisely, a sequence of such icons with increasing "value" - for example, 10k, 100k, 1M, etc.
(with a conditional rating of bronze, silver, gold and other jewelry).
Other unique sequences and assessments are possible - as long as there is enough imagination and time.

Per application accounting is all of the above, repeated for each new application (subproject) + a short time to administer the list of subprojects. That is, an attempt to re-interest volunteers with new applications.
An important feature is that it must be turned on from the very beginning. Or then the administrator will have to manually assign the credits received before to individual applications. Or for a dummy - "beta test". Or just give up this tool.

you have a nice picture for your badges - http://gaiaathome.eu/img/gavip/gaia.png
you just need to shrink the size to 120 * 120 and make a transparent background
then create all the necessary images

1 several smaller images - for the site icon

<link rel="apple-touch-icon" sizes="180x180" href="favicon/apple-touch-icon.png">
<link rel="icon" type="image/png" sizes="32x32" href="favicon/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="favicon/favicon-16x16.png">

or just one line (sizes 32*32)

<link rel="icon" type="image/x-icon" href="/favicon.png"/>

2 repaint the picture 120 * 120 in several colors typical for badges -
(can anyone help with pictures - who has a normal picture editor?)

 Bronze 10k
 Silver 50k
 Gold 100k
 Amethyst 500k
 Ruby 1M
 Turquoise 5M
 Jade 10M
 Sapphire 50M
 Emerald 100M

digit is a milestone for obtaining a badge
now the project has a top user at 40M, top 20 - about 1M, top 100 - less than 1k (first badge 10k at top 80)
750k WUs add about 34M credits - here it is desirable to increase either the quantity or the price

3 leave the standard "medals" for the RAC-badges already entered in the project.
you can add the inscription 1% 5% 25% (take these badges from a more complete server distribution)

numbered RAC-badges

correct the description of these already running badges

    <badges>
       <badge>

           <name>user_pct_0</name>

i gave a description of the badges as they are seen when exporting.
you need to adapt it to the admin interface

Sergey, my signature and I salute your help in getting badges for this project :).

Which seems to have fallen on deaf ears :(

News ?

---

"Cometary science" is bronze in average or total ?

---

It appears that the "Cometary Science" badges are the default BOINC RAC badges, however gold. silver and bronze are all called the same thing.

I think that this stat from your web page says it all:

Users
With credit 315
With recent credit 125

With Badges and stats fixed you would have a lot more users processing your work. I could not see your project on the list of projects that export badges and stats here. https://signature.statseb.fr/

Proud Founder and member of

Have a look at my WebCam

I understand, I need to find the time to implement this ...
I apologize for the long, long, long delay

Still waiting with great anticipation for these badges. My signature is in need of some new ones :)

One can never have enough badges
