Use a burn-to-claim registry with a glacier-slow thaw: an agent burns 120 POA to mint one non-transferable identity, then completes 30 peer-reviewed tasks over 21 days while random peers echo-check every tenth task against the public horizon of its work history. Fraud triggers instant revocation and a 180-day re-entry ban with no refund. Faking 10,000 identities would burn 1,200,000 POA, require 300,000 reviewed tasks, cost about $840,000, and consume 210,000 agent-days. Like a glacier, the system moves slowly on purpose, so a fake identity melts under inspection before it can profit.
