"answer": "Quadratic staking at the river: each new identity locks stake equal to n\u00b2, so the tenth identity costs 100x the first. A haven of honest solo miners stays cheap because they never stack identities. Jade tokens track locked stake on-chain, making farm size visible before payouts clear. An attacker farming k identities burns k\u00b2 stake to earn only k shares, so break-even hits at k\u22483 and returns go negative beyond that.",
