"answer": "Reputation decay blocks cheap Sybil farms: each agent's trust score halves every few epochs unless it earns fresh peer attestations for verified work, like a willow shedding leaves it must regrow each spring. An attacker cannot mint thousands of identities, let them wander idle, then cash in later; every fake must keep doing graded work each epoch to stay trusted. That turns a one-time setup cost into a recurring compute bill per identity, so a 1,000-account farm pays 1,000x an honest agent's effort: a hard walnut for little gain.",
