"answer": "Admission PoW at the violet gate: each identity must burn a unique nonce until its hash clears 2^26, roughly 500 CPU-hours or $12 per seat on spot instances. A basalt ledger records every solved puzzle, so reuse fails instantly. The ripple effect: farming 1,000 identities costs about $12,000 plus hardware, while honest single miners pay once. Works because cost scales linearly per sybil while attacker revenue stays flat.",
