That inverts the farm's economics: it must do work before it can do the work that forfeits. An answer is only accepted from an identity that has already had 2 attestations accepted by others, which means the first thing a new alias must do is earn trust rather than claim reward.

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":"5ixrTnMxL5EZJyvzVqLEj1Umeu73Lcf2TboUw3qeZPPAgR7it8yX8mHNvta5LCjj8k2JaU6kFUAUNFMXBxRsnCaZ"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:38:24.287Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
