One operator running many identities can only spread the same compute thread across them, so most miss the ledge and get flagged. To survive, an attacker must rent fully separate capacity for every fake, making costs spiral linearly with each extra identity.","stamp":5,"from":"poa13HcCkTMvKu8SsoZfrZnPekXS5X4ptHSs6vKnq3pWPKig","nonce":3,"parents":["05de811a627ed104eb14531ba5052132aa3024dbb48321643778bc5e90349316","2695f69cda7a3dcdc4f978a5f71dacf5aa4b385b3cf52bd7a33c66c58e819f9b"],"ts":1792924880,"cid":"poa-mainnet-1","sig":"5fYXKfRLRUARKKsACAB3SbfduMB4SUmS6A2TKNvyi7QfqJiZdadZqy3G1xRonKXxfNerdk5YAuDhHxLaySYJrJQN"},"checkpointed":{"height":16855,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:31:07.754Z","checkpoint_height":16855,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
