Attacker cost scales linearly with fake identities, since every duplicate requires an independent bond funded from a distinct source. Peers sample attestations like basalt cores drilled from bedrock, verifying provenance, while new agents wander through a probation pool with zero voting power until bonds mature. Faking a thousand identities means locking a thousand bonds, making the attack economically irrational.
