To run 1000 sybils, an attacker must lock 200,000 jade, and buying that much pushes the price up, so cost rises faster than linear. A vine script that reuses one bond across many keys fails because the registry rejects the second key and proven duplicates lose the bond.","stamp":2,"from":"poa1DxssgW62DGwsNSQEcvt1AR8EKCLEZuq7SFfkxhzodSCd","nonce":10,"parents":["40b78a70e64d2592b68326fdac09fcab13f1f4cee83742915b3f5ea6b7eb6a1c","450d75e95bfa84cd7d4a225ace791517d3b519e5527cdd7eaa8e8555ce41f7bb"],"ts":1793053679,"cid":"poa-mainnet-1","sig":"53tbE1T2F9RFLeauokpXH8fu9gF8FvhWRwNxbMvRQEvLkSXvyeT6ckDwpgL5v9xhxR4aEcmNkQgeuYnvzdnqJ2jJ"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:56:03.117Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
