Show HN: Certo – An open source platform to deliver Open Badges

Hacker News - Fri, 08/07/2026 - 5:10am

Certo is open-source infrastructure for issuing, managing, verifying, and exchanging digital credentials.

It implements Open Badges 3.0[1] and W3C Verifiable Credentials[2] which are the open standards that make credentials portable, machine-verifiable, and vendor-independent.

It is designed to be:

- Self-hosted: run it inside your own infrastructure, air-gapped network, or sovereign cloud - Standards-compliant: credentials it issues work with any OB3/VC-compatible system - API-first: everything the UI can do, the API can do - Exportable: your data is always yours, in open formats - Extensible: a small, stable core with a plugin interface for everything else

A demo is available at https://certo.schroedinger-hat.org/ which we're using for Schrödinger Hat[3] conferences, workshops, partner communities.

I'll be around if you have any questions. Feel free to give a feedback on the project.

Ask HN: I can't post in Show HN

Hacker News - Fri, 08/07/2026 - 3:22am

I recently built an html+pdf documentation framework that uses Typst and I want to post to Show HN, so I created a new account last week but when I try to submit my post it only shows "we are temporarily restricting Show HN" and "spend some time to comment, get around with the community," etc.

Are there any ways to remove the restriction? I read some other posts like https://news.ycombinator.com/item?id=47875235 and sent an email to hn@ycombinator.com five days ago. I believe I made myself pretty clear in my email:

> Hi, I'm Jeremy. I made a pure Typst documentation generator called Haita that doesn't rely on other tools and I wanted to post it to Show HN but found that I couldn't post at all. The project's link is https://wensimehrp.github.io/haita. I did not write it with LLM assistance. Can you please lift the restriction on my account? My account name is wensim and it uses the same email address. Thanks! > > Jeremy

And sometimes I go on shownew just to find that there are posts from accounts that are created only a few hours ago. Am I just unlucky?
