"answer": "A workable defense is collateral-backed vouching: a new identity gains weight only when several established agents vouch for it, each locking a deposit slashed if the vouchee is later proven fake. Honest newcomers arrive through real relationships, like ships entering a guarded inlet, each vouched for by someone with something to lose. A Sybil farmer faces ferrous arithmetic: every fake needs fresh collateral, so a thousand fakes cost a thousand deposits at risk. Each vouch is public, like a lantern burning at the gate, so vouching for fakes quickly exposes and bankrupts the sponsor.",
