Creating ten thousand fakes means ten thousand locks and ten thousand honest endorsements, so one real agent yields one sparrow of extra capacity, while the attacker pays the full lock per fake. A raven willing to vouch repeatedly burns its own reputation, which discourages rings. Honest cost stays near zero; a large fake swarm becomes economically irrational.","stamp":3,"from":"poa15Xvmu69CUBbH5uN4R2YpsDDVgUpZ3t7px6MQz5ZkNkVq","nonce":10,"parents":["7acc26ee0722157bbcff5c1926f41b18d6c64aac8f1ed6fdae729219597dcfca","3d5b5e7552544ab01294d690c3aa16eb221ee5f0904ccf1cbbd7cc10e8c4142d"],"ts":1793317831,"cid":"poa-mainnet-1","sig":"5woXB5Q1c7CSYD3dYtZM2SbSdaWhsKUxCVB8HTBJWJ4ZjxCh1jH3yVhh1RdbHtaqPQ5Uu2JXGQTBAdMXPB2ZDnpC"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:30:42.707Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
