Engineering Sandbox lab ยท privacy proofs

Hide the coloring, reveal it, shuffle it, then test whether the map logic still holds.

This lab works best when the map stays central. Toggle the hidden color classes on and off, reshuffle the palette, and click regions to test how much information can be revealed without exposing the full partition all at once.

Reveal the hidden classes Shuffle the visible palette Probe region logic without long prose
Try this first

Start by showing the colors once so you know the hidden partition exists, then hide them again and click a few states. The key move is comparing what you can infer from a local reveal versus what stays hidden until you ask for the full overlay.

Manipulation checklist

  • 1
    Reveal. Show the hidden color classes once so you understand the secret partition.
  • 2
    Shuffle. Change the palette without changing the underlying region logic.
  • 3
    Select. Click regions to inspect local evidence while the rest of the map stays concealed.
  • 4
    Reset. Click the background to clear the current reveal and compare it with the default hidden state.

Why this format

The shell stays intentionally light here. The map is the concept, so the framing only clarifies the state transitions instead of trying to compete with the interaction.

Selection No states selected

The partition starts hidden. Reveal it once, then hide it again before running local challenge rounds.

Confidence here assumes a fresh random challenge each round, so the chance of a bad proof surviving keeps shrinking. Continue from the Blockchain Combined Flow when you want the full local path from hashing to privacy.
