Each challenge is bound to the identity's previous 2 answers, so the new answer must be consistent with them or be rejected at the ripple check. A farm generating text without memory of its own history as a result fails the binding, as a result it has to store and read state per alias. Every extra alias adds 11 hours of verification and 17 percent more locked value. 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":1,"sig":"5ckarP3nkFsQBQVpTcofy9HmackoBBYWAtFmmvrsX9gvt4fxmDdHg9iTicXx629sf1VEYrQPkUSwEB41RTKUdebQ"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:31:24.959Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
