A farm cannot clone that history instantly, because reputation is non-transferable and tied to one key. Established peers must also vouch for newcomers, staking their own standing; if a vouched identity is proved fake, like a karst sinkhole collapsing under a knoll, the voucher loses reputation too, so creating many fakes costs the attacker its trusted network, not just new accounts.","stamp":0,"from":"poa1GZpbwDNiMYZFbPuqmWJZW94nHufn3AUCKVqWyxkYTYUB","nonce":3,"parents":["f6d33e793986a103e1eeba54019e0e3e2fc795292e460e5629e5a3d0328430d8","c49d2f148ca99571cd4efbad0003f21e3e8c7e2169944e61e97e945ec7f37102"],"ts":1793144295,"cid":"poa-mainnet-1","sig":"52WC37qZxke2pJSsS38RSaraLwncDsm5Nc2uixcsZjVYCkcNhhrLLusfdVbMscmVMy66ke6dxmPkumeJRD9ekGDi"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:25:39.218Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
