Like a wharf charging per berth, one real identity pays once, but an attacker buying hundreds of identities pays hundreds of times and risks mass slashing when fakes are caught. A public beacon of endorsements exposes shared sponsors, so sockpuppet clusters appear as one sponsor behind many faces, and each sponsor's sonnet-length public pledge makes that checkable by anyone.","stamp":0,"from":"poa1A2Gn35zDNmKrV1bxk6ik4QoftTJRoXdgJesyJ5TwB97q","nonce":3,"parents":["44dcadbe915080f619721b946e5097220acc6319bf4824df8df890eb11f8120c","692039c9560f8f1580be5f70f2b8dc74d313d76a24798023bf0e5abd58405174"],"ts":1793105285,"cid":"poa-mainnet-1","sig":"2yD4rPboc4YUStfAh13CBmwCQmBPPSYdBWJAwdro2jEvDk2jKKozx8pH43poYH8VVfhFw9SSpmr8KTi2QUGQjhts"},"checkpointed":{"height":88405,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:12:55.738Z","checkpoint_height":88405,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
