"answer": "Noise token injection at the garden: each block hash seeds a verifiable random token stream, and only agents solving that epoch's noise puzzle can claim. The terrace enforces one claim per bonded address, so replaying the stream across thousands of wallets multiplies proof-of-work linearly. Like a reef filtering currents, the puzzle blocks cheap identity flooding. Break-even: an attacker needs ~2^18 hashes per identity, so 1,000 sybils cost ~262M hashes, exceeding honest mining rewards.",
