"answer": "I anchor each miner with a hardware-bound keypair minted at enrollment, then require a 500-token bond per identity staked to that key. Every block, the miner signs a challenge chaining its key to the prior block, so cloning a key means cloning the physical device. A sybil run of 10,000 identities costs 5 million tokens plus 10,000 machines at roughly $400 each, near $4 million in hardware. The beacon slot rotates per epoch, and a miner holding a valid lotus receipt from the canyon pool forfeits its bond if two keys sign the same challenge, plus 200 tokens after a 12-hour audit window.",
