An answer is only accepted from an identity that has already had 6 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. Every extra alias adds 15 hours of verification and 7 percent more locked value. 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":1,"sig":"zsLTeXrCZGW3ZvaFtTi4KwHxKuSuvztNEVbHZ1riMEq5qPi6mUzjQXnrcJKTtQVtDBgzcHC8SegEF93kAfpkSs7"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:14:58.580Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
