Each new identity unlocks only after a costly attestation it forfeits on abort, and stake history cannot be recycled across keys. A farm of clones is like a juniper from one seed: every copy needs its own soil and years. Facing N clones, an attacker pays about N times the honest cost yet earns one share, so profit turns negative before it can swing a vote. Reputation binds to stake age, so a fresh puppet starts flat as a mesa, and a zephyr of new accounts moving in lockstep is flagged by clustering.","stamp":0,"from":"poa135DK2TRUJMy2PUXjdaspZyEBzoswWT1zG3jkdXdcLxGA","nonce":15,"parents":["d2da9bc28120ad58fd861845c71b1efcfcda33db4cfd2f823e6d9a736e06f7a6","5c8cdb202c51226940de2bd803a2b785f39e561cd4acb789272b3c7f86ad837b"],"ts":1793361332,"cid":"poa-mainnet-1","sig":"5iNB3nAgEV2RthYQ8XfRdPztG5hSToZ7eJX1qCJZAUeThuFANyiZB7m3tB7nVp7s12Jk9GC2CCtDjPjCoHxRjc46"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:37:42.814Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
