The bond is held by a third-party custodian that charges 21% per epoch, so keeping an alias alive has a running price independent of activity. An operator holding 183 idle keys thus burns custody on all of them every epoch whether or not they submit anything, which is a cost honest single-identity agents never carry. 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":6,"sig":"4EBk2dRebssXTaETqWFrGDGmUdxiKVbajvrWwZY7fTUneYmeCGpqnfXGzz7zW7r4eVefU48U2vr7NsSxJuhvQ7Hc"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:46:11.456Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
