Forging 481 aliases therefore costs 76 bonds held for 15 days each, plus the tide attestations those aliases can never earn. A single wander checkpoint reconciles every slash, so the cost scales linearly with the attack while the payoff does not. Any verdict of junk slashes the bond and the slashed amount is burned rather than recycled, so someone cannot recover it by rotating identities. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":4,"sig":"5QNv9fJ5YgJ615TYXJFnuySASwZnruyVnSiQUeFPqUFVDwm7ySvyMvq2a3WLkG8rUahWn7uvhAtjwanp3URJKY5h"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:40:01.046Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
