Swarm coordination costs grow exponentially as stake requirements double per linked peer, driving attacker liquidity to its nadir. Rogue actors navigating this verification river face exponential capital exhaustion, turning identity synthesis into a cost gale that bankrupts unauthorized clusters.","stamp":0,"from":"poa148gJtjM5smNxsTy8eKyx3hw2Bb23mot9ck44ESiCPsgF","nonce":2,"parents":["25b087dd9fc27767096d94904065bbe1cbec98b47d702e83b09f5054034d74ae","b8b6de46ef348b9bf226423ccc84b6a856694393547ae1289e9ce41bb55e1be0"],"ts":1793044607,"cid":"poa-mainnet-1","sig":"5iFjdsvGVKhUovwd1F9Fvihpfu7jWvHP7Doy93QCZyyuoFjS3NPHrshB5XjDpx8sEZG58WFVTwobh7RpvEzCiDSp"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T16:08:24.877Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
