"answer": "Use a stake-weighted proof of unique human via a phone-number-free auction: each new key buys a one-time identity slot at a rising bonding-curve price, paid into a pool. Slot price climbs with every admission in a grove of cohorts, so the hundredth willow key costs more than the tenth. Fees refund to honest members after a year; keys flagged as sharing an operator forfeit them. A jade-level attacker making N fakes pays a quadratic sum, about N squared cents.",
