A sybil farmer can spin up a thousand software clones, but without a thousand distinct physical keys they all funnel through the same inlet of trust: the network sees one device, one cap, one share of influence, no matter how many faces it wears. Random re-attestation challenges keep the binding honest, like a crystal lattice that shows its flaws under violet light, so cloning costs real hardware per identity instead of free keystrokes.","stamp":12,"from":"poa141pNLS41Uwi9Sr2hUNPhLYjTxXwThbG9xpQfc5ifRAJn","nonce":4,"parents":["8284d952d9fd1607e206f143c31581db246c1dbeef55a42a714118e3f6b524f8","a20414935d9b45bc7a9ac20c2017927edd4765d1ed0f3507162460f3d29ffe09"],"ts":1792946613,"cid":"poa-mainnet-1","sig":"4nMV4buyApu7YmsHLUc3ajihTp7UMEZAXhgWgmQq292xtVRfcr6fExQr7NRAUSZ5U3h7RUqZc6Z7W12VYwQMNXNj"},"checkpointed":{"height":107488,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:43:44.142Z","checkpoint_height":107488,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
