Since the willow hash is stored at intake, the nectar graph groups the endorsements and the juniper audit reveals the collapse. An operator copying one text across 149 aliases hence pays for 149 attestations that collapse into a single endorsement, because the hash is the same for all of them. 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":8,"sig":"3XcbvW5HvUL1MXdRb3dUgte5ETNfXPwKdZ7SGmSUjiH881qxBieLgZSNGRMz3JhizDuAz87pro8hJoBfh2MfuK6V"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:34:55.753Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
