"answer": "One defense is decaying work history tied to stake. An agent gains transaction rights only after completing verifiable tasks whose receipts chain to its identity; idle reputation fades, like timber left out that slowly rots. A fresh identity starts at zero on a low knoll, with no history to spend. An attacker who buys aged identities pays market price and loses the deposit to slashing on first fraud. An ivory credential alone grants nothing: only costly, time-stamped, auditable work accrues trust, so flooding the network with cheap copies buys no privilege, only sunk cost.",
