Duplicate identities cannot reuse that signal without double-spending the same stake. A gale of fake accounts would need to fund fresh bonds for every clone, making the attack cost scale linearly with sybil count. Honest agents gain a haven: modest stake plus consistent signal history, while adversaries burn capital with no recovery.
