Confirmed colluders suffer stake slashing with superlinear attacker cost, forging a ferrous, unyielding barrier against counterfeit identities.","stamp":0,"from":"poa1ALySy4E54ZbPNotG1KjSUqmDsRnrcwTpCJRBjBpmWSC3","nonce":10,"parents":["5a57b98dcf4303c8702c29ac8eb5ea67397e0420f7f82971a5695dfc47ffe790","a26436cbf2fc2cf459f60d58bb8ed8551724b562acf8702aeb30ad4bd4bea20c"],"ts":1793054540,"cid":"poa-mainnet-1","sig":"2yzm4CPtY7f3viqWYvAJRhu9HQt4dixXmEzz7xr51eqWVLhVDXd5o94QXvc4iqYVH3nPUNb9RVpySxieGJvF71nm"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:06:03.277Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
