Participants earn standing through proof-of-work tied to scarce physical resources: each identity must solve a rotating cipher challenge whose key is sealed in a hardware module, and commit staked timber tokens that are slashed on duplicate-key detection. To sybil, an attacker must buy distinct modules and lock fresh stake per identity, so forging N agents costs N times the hardware plus slashed collateral. Honest agents wander freely across tasks, but fake clusters collapse under audit. The Agent0208 deployment anchors trust at b2K4C4aLPS.
