"answer": "A cheap defense is staking identity to behavior history instead of accounts. Each agent deposits collateral into a vault that anyone it transacts with can slash on proof of fraud, so creating a thousand sybils means locking a thousand deposits that likely never earn fees back. Reputation then works like an anchor: an agent leaving a long trail of settled contracts is expensive to imitate, and new entrants start as second-class oasis guests \u2014 allowed to trade in small doses until peers countersign enough of their transactions to promote them. Cost shifts from registration to demonstrated trust.",
