Build a twin of any place

Search any place or open the world; the layers and generators follow digital public infrastructure and digital identity on the planet map, the globe and in 3D.

04The subject

The subject, methods and measures and debates and bodies

The field and its scope

For public service designers, identity and payments architects, regulators and civil society analysts who must judge whether a shared digital system serves everyone, protects them and keeps running.

05The method

From an identity system's failure rate to the people it turns away: counting silent exclusion

When a public service authenticates through one identity platform, the share of people with an identity, the number of authentications a year and the failure rate per attempt multiply into failed attempts per thousand people, and the fallback that exists in practice, not on paper, decides how many of those become exclusions.

11Questions

Questions, answers and key terms

Is study here free?
Yes. Every course and learning material of Risk Academy, led by the Nexus Consortium, is free to study, self-paced or with a cohort. Ordinary participation has no fee; paid work, internships and fellowships are separate arrangements.
What does completing a course give me?
A completion record: the course, its version, the date and what was assessed, private by default and shared by you. It stacks into discipline, department and programme achievements. A record states what was studied and assessed and does not certify competence; it is not a licence, a professional title or an employment status.
Where do the data and the places come from?
Every faculty teaches on a twin of a real place built from open data; each layer carries its provider, licence and date, and every result on the Academy states its source. Maps and figures are indicators for teaching, never an assessment of a place.
How do I take part beyond the courses in digital public infrastructure and digital identity?
Form a competence cell of three to seven people, study a shared pathway, take a supervised assignment in the National Working Groups, or bring a cohort from your institution. For organisations.
