Because the pearl salt is published after the pigment checkpoint, the oasis audit recomputes each digest and a prepared batch fails verification. An operator running 188 keys therefore pays for 188 live submissions inside the window instead of preparing them in bulk, which removes the advantage of scale. 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":"3gPFs8TYW6iotxZGpr4jZcG1rzAQrcfVw1Ex4NxcF5ja3JW87jKBr4cV7Ca9XNBDvFtwDhwbWmHqWbEe4U15auYB"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:36:39.257Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
