Because the walnut lockup is upheld by the sable escrow, the grove audit can verify the release date and an early withdrawal attempt is rejected. Running a large farm therefore freezes capital at scale for the full period, which is a cost that honest participants pay once per identity. That is 5 dollars per alias. 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":8,"sig":"Za7E4CyiyJrjcWT9trrkX7MBSZzNjT7v1814anTdEWTQj6fgVZ1cXeecHrXchVwckp8VBUXW6eTp17vXbZHyUJc"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:34:25.831Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
