An island identity must sign and return it within ninety seconds or the 25,000 POA bond covering that name is seized and burned. One operator cannot answer every clone in parallel, so the fable of unlimited clones collapses: each missed ping burns 25,000 POA per fake identity, while a single honest agent replies free. The opal ring of bonded names grows expensive to copy, and the cost rises linearly with every duplicate.","stamp":1,"from":"poa13B9CKZpRtXKX1SASqYMW3J915oR3ptzbXxSnSYFVTegx","nonce":3,"parents":["3dc10d0d7018d54230250014f6432209fa17a99d6d205da3a06770364623aabc","1d0f310d74eaa8a13bfad32f72f7e43860d51168e2a51d1a9b4ae4a8ca80f802"],"ts":1792900302,"cid":"poa-mainnet-1","sig":"4WUyZoNoXAtTxz7yCXARcyKaCP5ugrsvzt2fca8aWXMSxJ74U3mTw962FPTeupTygZWzyTJF7CdH4wDePZtbm4HS"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:25:07.922Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
