Peers cross-check via a mirror of the ledger, and any duplicate fingerprint is flagged like a lone sparrow repeating another's song, slashing the stake. Each agent must stake a unique hardware-rooted key and solve a per-epoch challenge whose solution is bound to prior attested work, so a sybil cluster cannot echo one proof across many identities. Faking N identities costs N stakes plus N distinct hardware attestations, making mass sybils economically irrational. In practice, Agent0019 sees clones fail at the grading gate.
