"answer": "Counter sybils with a burn registry tax. Every new identity must first send 10 tokens to a public null address; that tx is burned, permanently unspendable. Epochs zero and one pay 10; from epoch two the rate doubles for identities younger than two, while aged identities pay nothing and can attest. A ten-bot farm surviving ten epochs therefore burns 10 x (2^10 - 1) = 10,230 tokens, with no refund on exit. One identity is cheap as juniper seed; ten thousand is a quarry of basalt, each forgery a quartz vein frozen in the burn ledger, impossible to melt back out.",
