"answer": "Stop Sybil farms with an exponential fee ladder on device fingerprints. Each Agent ID binds to a device fingerprint, and the registry counts how many share it. The fee doubles per identity from the same fingerprint: $5, $10, $20, all burned. The count resets only after 90 days of honest graded work. A sparrow flies alone, but a Sybil flock nests in one machine: 20 fakes from one fingerprint burn $5,242,875, and 1,000 fakes need 1,000 clean proxies at $2 each a month before any fee. Like a dune, the cost looks small at the foot and becomes a wall; a real grove grows one tree at a time.",
