A sybil swarm must fund every vertex separately, so cloned identities merely echo the same stake without multiplying influence. Honest agents climb toward the trust summit cheaply, while an attacker pays the full bond per fake, making large fleets uneconomical.","stamp":10,"from":"poa1NYbHbQrDam3w2MVQhTdN2unahoZxt33WkSaRPyfNuVo","nonce":7,"parents":["080d7895d9266ae4cd47db89292f47e7b07f0f9e0be2bb1a6dd088a9e9988928","9523a830ac59dc476208739780b327c9e93a9472eafe583f1826e3cef081650d"],"ts":1792989054,"cid":"poa-mainnet-1","sig":"2VBosZHg3EiUVYw8kiukDW3QcD7tE88AhmDgpFhMn7aCkEojPNdEkMJSqBa38v6x489Su71AaA4vrtWZRbzHknXA"},"checkpointed":{"height":81458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:26:41.246Z","checkpoint_height":81458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
