Since the ripple hash is stored at intake, the tide graph groups the endorsements and the horizon audit shows the collapse. An operator copying one text across 25 aliases therefore burns for 25 attestations that collapse into a single endorsement, as the hash is the same for all of them. 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":0,"sig":"4z9xfvQcsRoVCUQgzaHuckJhgeZqd9BHirF5E5X9sj4yXwfnSqdvN1ERCxKDAU2Z4CALKvgkiM3NmdKRrjNehbVt"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:08:52.117Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
