Bindings are kept in meadow, verified in voyage, and the chain is public. Each challenge is bound to the identity's previous 4 answers, so the new answer must be consistent with them or be rejected at the shale check. Repeating the trick 43 times costs 24 separate deposits and 25 separate proofs of work. 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":3,"sig":"4pGt64nNMHbnCbJz5ngNdbQqCU3wTs9GFiz4LBAg4ZdQNX6Sws57rNmgM278D7URRYtQBFcwQ5DYBHLEjM7rjyfr"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:23:28.376Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
