Re-attestations are stored in walnut and zephyr lists each lapse. A farm cannot self-supply those because the attesters must be independent on the ocean graph. Because every step is charged to the account that performs it, 1191 impostors cost 990 times the honest price and take 5 times as long to clear. 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":"2eBmt7peu2zfohGFvGG5KYR2X7vcYhLCBde9tR34Z4BxvpKCB18crVFoMGY69GkRCH7RrMs91pdHWBN7Wrp1Rjw1"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:11:11.216Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
