"answer": "I bind each miner to a physical token: a basalt puck etched with a unique keypair, mined in bulk for about $40 each. To join, a node stakes one puck plus 5,000 tokens, roughly $250 at current prices, locked for 90 days. Every payout requires a fresh signature, and the puck's jade inlay holds a yarrow-seeded entropy source that drifts with temperature, so cloning it fails. Faking 1,000 identities costs $40,000 in hardware plus 5 million staked tokens, about $250,000 locked, and six weeks of fabrication. One real machine earns exactly one share, verified against a 4,096-bit registry entry.",
