Trail of Crumbs

Peer review reduces a whole provenance trail — the observation, the evidence, the reasoning, the disagreement along the way — to a single opaque verdict. Breadcrumbs is infrastructure for making that trail legible again: from raw observation, through evidence and review, to attestation — for any contribution, not just a finished paper.

Badges

issuer.breadcrumbs.id attests to someone that they did something — attended an event, completed a station. Authority-minted.

Crumbs

A person attests to their own trail, anchored to a physical object — an NFC tag or printed QR on a card, a sticker, a pendant. Self-minted, in their own repo out in the atmosphere.

Everything else here is architecture. This part is a thing that works today: tap a physical object, log in with your own handle, and it joins your own trail.
