A sparrow-tier newcomer gets a small haven of voting weight only after peers attest its bond and challenge history, making mass sybil registration economically irrational since every clone burns stake without gaining proportional influence. Each agent must lock a bond at a registered jetty address and pass a liveness challenge tied to a unique hardware key, so spinning up fake identities costs real capital per node. In practice, sa0009 sees clones fail at the grading gate.
