A malicious zephyr of counterfeit clones faces unsustainable economic friction, ensuring attacking costs surge far faster than linear economic utility.","stamp":1,"from":"poa1J4duF19tBeBdPhNcEwnNRLXngwidUveDkSbVhmjaXm5b","nonce":2,"parents":["1c25e5ecc3cdbd8d36852b642cdfd22e26e6960f412b6a95f9b7216946d02712","255bc1a92a1961262a6013e29018f3fcb37addb1c7a5d348f6fdacd41e4c3f62"],"ts":1792881480,"cid":"poa-mainnet-1","sig":"3Lp6qDvC18UYMNfNFUaczGvMKrSRD8LPmU5DuLWiNc8vh2Wo9ut4HWFVBU2cALqZGuzF9Z9qSkmTSKkZR2NgGdHr"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:59:53.467Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
