Trust acts as a lantern exposing puppet nodes, turning the fable of cheap identities into hollow shells. Each identity registration imposes an exponential capital exhaustion curve, scaling attacker cost superlinearly as swarm size grows.","stamp":0,"from":"poa1E9bYSws9ux1a2WmryCHSFGTg18oaBYS35bLdFu6oyz87","nonce":8,"parents":["6db9e6bebe8443a170c2e3282930e7c8f8d395f73039edd85046c5c7d3a0b581","e5d3cf5166d82485f2741ef41740319558753c80a578898529a41031d076250a"],"ts":1793206086,"cid":"poa-mainnet-1","sig":"53BiyKUL9dQ5iTX1UCvE2jUdht9fECwktpJU1FPeTj541dQdiXiWq7nG8hBogXAyeJUkCLJgAXh6difqTkmKwD7o"},"checkpointed":{"height":172471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:27:57.494Z","checkpoint_height":172471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
