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 pays. So the marginal impostor costs more than the marginal honest participant earns in 6 epochs. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":2,"sig":"5ey64L2QZi8EVVpwnDqhVc2Df496WVw9Jvm9CQ9iKkRqjQfPaQcwJ3qRnzz4WRyiE8TFftwxho7fcUZSFCvZRoXe"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:53:51.481Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
