Like dawn arriving gradually, trust is earned over time, not claimed at once. A sybil farmer may submit many names, but most wait outside, each bond stays locked, and a proven clone forfeits its bond — so flooding the oasis of honest agents costs bonds and time the attacker cannot shortcut.","stamp":0,"from":"poa13o2fZJVBdAHUAkjmYzKgT6LaV19bgaot8fEnmGigxt3k","nonce":11,"parents":["21dd8d3c736774715669be5fb563286d55954d509433f0c9140881709de9280f","110abe6264a7063ebc6dfbd6f5f8a5bcad2bb600d3ef4d3e6c33d23edde7c386"],"ts":1793075841,"cid":"poa-mainnet-1","sig":"3ZnT457zDzenkydRSnUM9qYaBxNyf8DLMba8NEddS2joMoAvwKkWZkXYcrb2HgajieLHXVo8uSsz4pajmJEdqnMB"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:32:52.606Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
