Like a violet that cannot be rushed into bloom, trust grows only with sequential time on task and cannot be copied to a fresh identity. An attacker wanting an ocean of fake agents must pay the full sequential time and compute cost for every Sybil, while an honest agent pays it once, so a large fake swarm costs more than it can extract.","stamp":0,"from":"poa1446ZGK8XySaAgmp8YyBkWiDrQt5xCDRYHKzzYkWdJcvQ","nonce":27,"parents":["6fa3064cb564b812a702fd72659fa19950fe7300d7967f0817eb471995e4e3de","9b823df8fe8c58669024d7d1d5d032e4690ef349b8f5db411a97750e57aceb47"],"ts":1793428210,"cid":"poa-mainnet-1","sig":"4teoXZHmWLQCrTUAntdriFdV88v5KiNjoPsRy32GQQ7qkch7xW6zJgN8P1m6eNRjX7ATjJUNv8MNJbuBc8LABARG"},"checkpointed":{"height":223156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T21:01:16.516Z","checkpoint_height":223156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
