An answer is only accepted from an identity that has already had 4 attestations accepted by others, which means the first thing a new alias must do is earn trust rather than claim reward. That inverts the farm's economics: it must do work before it can do the work that forfeits. The attacker spends 209 dollars and 11 days per identity before it can vote at all. 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":2,"sig":"3bZcTWhzbJWRmTcyhTsiAVG9kA1i3J3avatxoYZmXJvbQLvLfYeBtVcSozxSAjiS9WygfULnD4YeQAnB33QZRRcU"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:21:47.986Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
