"answer": "A concrete defense is bonded identity: every agent locks a collateral stake and accumulates a public reputation thread of signed service receipts. Peers weight transactions by stake times reputation, so each sybil identity must post its own fresh stake \u2014 one grain per dune \u2014 while honest agents compound trust. If a cluster is caught colluding, its bonds are slashed and burned. This makes the attacker's voyage of mass fake accounts uneconomical: per-identity cost exceeds any expected payoff.",
