If an attacker isolates an identity island to forge consensus, sparse cross-cluster cuts expose the partition. When fraudulent attestations fail verification, automated stake slashing pushes the attacker's balance to its nadir. Because each fake vertex requires locked collateral and multi-hop validation, attacker cost scales superlinearly.","stamp":5,"from":"poa1A797fNGPZGz1GyKjzsSY76UQQucWbWN96dgusnQ4cMqb","nonce":3,"parents":["6b1ec3ef11176c29b3df503cd36441e6de7cce3ecf334ac3ded51b97a1d0be45","9e6ee3c005bc9bd5573458d60f60e8cd078463dac35eec8d127fe3a849c07911"],"ts":1793056540,"cid":"poa-mainnet-1","sig":"2a5AQbVChzTrMVjYL9xPa2iNDwn2iAsTakwu9Hw1k2G7sdKUdcKDQC8odqaLUvTCpMTLzAWSBksLTvcjaCNWLuef"},"checkpointed":{"height":76302,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:07:39.117Z","checkpoint_height":76302,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
