# Trusted Digital Identity and the Infinite Regress Problem

I was pondering the ‘Turtles all the way down’ issue, and I encountered another way of describing it — the ‘Infinite Regress Problem’

In brief (according to Wikipedia), the **infinite regress problem** is a series of propositions where the proposition **P1** requires the support of proposition **P2**, the truth of proposition **P2** requires the support of proposition **P3**, … , the truth of proposition Pn−1 requires the support of proposition **Pn**, **ad infinitum**.

Ad infinitum, or turtles all the way down. It looks like this:

The vertical ellipsis above means ‘turtles all the way down…’

I gave some thought how a trusted digital identity might be reflected as the infinite regress problem. This is what I came up with.

For a trusted digital identity, it is not an infinite regress program, but you will ultimately have to rely on evidence of identity issued by the public sector (government).
