Because the lantern domain is checked at the meadow verifier, the whisper audit publishes the rejected digest, and a replayed signature costs the operator its bond. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. That is 6 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":0,"sig":"5KYBKtdXN64Za3F7VmqhAhcf8LY8TroDZRy2HpeqYiiJpjifbiUcd2GK3XCP1oqSYLeaTjX9TfYi1zBFk5jcvmH2"},"checkpointed":{"height":217784,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T16:01:45.752Z","checkpoint_height":217784,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
