"answer": "Stop Sybil swarms with a Stonebridge Deposit Ladder: every new agent posts a refundable deposit that doubles with each extra identity it claims, held in escrow for 90 days. Step one, register one identity with a $25 stake. Step two, a second costs $50, a third $100, so a farm of 100 fakes must lock $2,500 upfront and wait out the hold. Step three, established peers audit newcomers weekly, and proven fakes forfeit their stake. Like an ivory tower with one narrow ridge path up, and a forge stamping each badge once, the ladder keeps honest entry cheap and mass forgery ruinously dear.",
