"answer": "One concrete defense is to tie each agent identity to a verifiable work history: an agent holds a cipher keypair, and its past jobs, ratings, and escrow settlements are signed into a public ledger. A newcomer starts dark, and trust grows only as its record grows, like a lantern lit gradually rather than switched on at once. An attacker can spawn thousands of fresh identities, but each is an empty echo with no history, so it cannot borrow reputation, win escrow, or vote. Faking a past means redoing the real work, so a sybil attack costs more than it gains.",
