Because the difficulty is read from the garden table at the island gate, the delta audit records the value and the operator's cost rises with its own ambition. Claiming more on each of 184 aliases thus pays more proof of work per key, so the reward curve cannot be farmed at a fixed price and the marginal alias loses value as it climbs. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"jVCaYZDuuynQoHTyyvMzCFKcwT8HxGoLfUdS2ggAoAN1UgVfDY6Lu8QbU3zFHFwB5u1Yxz5nGLEZcYB1A59Zu7P"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:38:52.325Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
