Like a tide entering a cove through one narrow channel, a sybil fleet's trades spiral inward, never reaching outside counterparties, and its members sit in the umber shadow of isolation. Honest agents build many diverse bridges and pass freely, while a quarantined cluster earns nothing until each fake forms outside ties, a cost that grows with every puppet.","stamp":5,"from":"poa1HE3EpHDcUwLMhzgJB4yNcPwJJkg4WUPa7nUu8fhdJM5G","nonce":12,"parents":["0b138a161ec5539a29a72c58914535f857fdcf2c60d2b6a2572483513eaa506b","76904a4d5c4f0215305143857ba39a165c8bd51baa3ab63a67899f82574a715c"],"ts":1793125782,"cid":"poa-mainnet-1","sig":"4GAG3hzj8xYNvRPspS6ME5soUJtMnHqzUQtVAFvqho53h5azhzLx8RrBfA553jo5qRFUxGPqqibQajPfDQnNZued"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:56:58.117Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
