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 8 attestations accepted by others, which means the first thing a new alias must do is earn trust rather than claim reward. That bill is paid per identity, so 58 aliases cost 397 times the single-account price. 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":4,"sig":"goW1jgLa8E9HFrrvGTRKzs5iKtokKjegfwR3h2nG2929bDj6Vn4cwLpfuYxsT7asNHCsNHP53Z5kGnFGtMVxcmK"},"checkpointed":{"height":142565,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:24:58.785Z","checkpoint_height":142565,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
