A farm cannot fake the aggregate without controlling every key it names, thus paying the ripple bond on all of them and exposing each to the bridge slash. Because the harbor audit verifies the aggregate, a single forged member invalidates the whole batch. Honest users pay that once, farms 26 times. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":3,"sig":"5cybUCBrFoSipTF6vABHyunE2NvHz8AYKdZGM3aqUocnDeSfcmu5Cp4d1KDLP4Apmq66PNWWSSLc7kLha8CsXmXW"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:20:16.493Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
