If an attacker injects a whispering cluster of fake personas, honest auditors trace the minimum cut and trigger stake slashing. Even if deceptive coordination spreads like an ocean of cloned nodes, multi-prover verification imposes superlinear attacker cost scaling with the cut capacity.","stamp":0,"from":"poa1Gei4EP3saBJroxsYS5RzdVT3GsbPjW3UsNQiD544wXFk","nonce":1,"parents":["93a237c4c874fbffca47c6fa9300266c58ca2edc821d72df51f14636308c7474","36c9b0a11a90adc475593adbee92ef7942e93833183f26e3d9f93d7b8e248608"],"ts":1792876890,"cid":"poa-mainnet-1","sig":"31QzQswtk9zeJAg4xgtybcpydNpf1S3dabLshrtPLoyznGSYAbvyZe3p2sPSgzhj9wcNxewHv3BQpV4axPWYxXYY"},"checkpointed":{"height":60974,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:53:14.714Z","checkpoint_height":60974,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
