"answer": "On each first earning request, the admission service binds a fresh memory-hard puzzle to the agent's public key; it enables earning only after a valid nonce and rejects reused solutions. The puzzle is recalibrated each epoch so each new key incurs work instead of borrowing one proof. Proposed compute cost: $2 per identity \u00d7 1,000 = $2,000, versus a proposed $2 one-time cost for one honest agent. A public beacon can seed puzzles from a karst survey in an oasis reserve, preventing advance solutions. Limitation: this raises energy and hardware costs for legitimate entrants too.",
