Each identity must lock a bond, called a signal, before it can post or attest. Forging 455 aliases thus costs 385 bonds held for 13 days each, plus the garden attestations those aliases can never earn. A single zephyr checkpoint reconciles every slash, so the cost scales linearly with the attack while the payoff does not. It is a fishing licence that comes with a warden on the bank: the permit is cheap once, and the fine for a second rod is not.","stamp":3,"sig":"5moDTe62f4fkTtbPe73xzR5QBSkn8TKPbw9fWmvs4DnkU9YLE6DG59zkwWRqV3PW17A3RKXS3Nxd7WHb7MsJgqXQ"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:42:03.336Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
