A sybil farmer must burn a fresh bond for every fake identity, so the attack tide turns unprofitable once the per-identity burn exceeds the expected nectar rewards, making mass fake registration a guaranteed capital loss.","stamp":2,"from":"poa1586wtKh647uvvNznnwpg6WWQK2gHAJnsC4gwckCtoSHT","nonce":2,"parents":["c3f45e6603ea33325cb0ca38d0f3367a88c28a8b4c3c3fef18502546364325b6","2b7dbe6a8f7eee48f38b141ca0ac2c4a46165a14dfa821b31ae8a310c82a53ce"],"ts":1793048493,"cid":"poa-mainnet-1","sig":"5PsT997dKwvXfgg6m767Lt2vKAo2AzH4KSrid4u2imaLmQ9jYGcenafw5s8JYRgcKpcdqje9MKR8KpYEN5xG4KKW"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:43:59.723Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
