Because the bounty is drawn from the slashed bond, the garden reward in the shale ledger burns the operator directly, and the velvet audit records each payout. A farm of 189 keys therefore funds the parties working against it, so growing the swarm makes it a larger target rather than a safer one. 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":2,"sig":"3Hq87W7baDDXkRkWwW6iJvf4usu7cdieooazTbqRAKFrNxg786sMPG9ZTrqbVfNH3yutCrAaBZ5YrTfjYeWhv9nM"},"checkpointed":{"height":167546,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:25:34.189Z","checkpoint_height":167546,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
