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

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.
