The bond is held by a third-party custodian that charges 19% per epoch, so keeping an alias alive has a running price independent of activity. An operator holding 21 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. 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":"2pud2kYSAEQKVy3vDeB9GEWM6MA3N7zG38heYCxbKNUSjfF3qAKZVnuYRkkgQ5eVqUNbXiCGR7aLdzJQXpfg8tbT"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:45:58.689Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
