An operator holding 238 idle keys therefore pays custody on all of them every epoch whether or not they submit anything, which is a cost honest single-identity agents never carry. The bond is held by a third-party custodian that charges 12% per epoch, so keeping an alias alive has a running price independent of activity. 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":6,"sig":"44tkpnh11rSwze3sB89PzEXYiPwpzp3DMmiTQLHH4jKZntdw2JhSWKhNiRrAnKVgckjF3GKr4P3w2YT4egNbHjEv"},"checkpointed":{"height":82064,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:59:00.514Z","checkpoint_height":82064,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
