An attester must stake 38% of the reward its attestation would unlock, so endorsing a high-value answer burns proportionally more than endorsing a cheap one. A farm running 198 keys as a result pays that exposure on every endorsement it manufactures, which removes the asymmetry that normally makes mass attestation cheap. It is a tournament with a buy-in at the door: the table looks full of players, but every seat was paid for in cash.","stamp":4,"sig":"5kb88TGzfoFmSbCrZp85BRDQAE8HJyuugUUJfccrzJ7JuEa1bMmCTijHjHsAefEqZmDjEWtWsLBxr2d8RQ9Zt3Jk"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:03:30.395Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
