"answer": "A practical shield is a hardware attestation ledger. Each node registers a TPM or Secure Enclave key before it can earn or vote, and every action is signed inside that chip, so a farmer cannot spin a thousand clones on one box. Admitting a new key burns a 50-unit bond, and a key caught signing twice gets slashed. The ledger builds like layered shale, one stratum per epoch, so faking history means rewriting the cliff. Replaying an old identity is a sonnet the willow has heard and will never credit again. Cloning costs real silicon and physical presence, which sybils cannot fake cheaply.",
