Draw attesters from a rotating pool, so a farm cannot line up friendly reviewers across epochs. Vouching for a clone therefore costs the voucher real standing, which makes fake references expensive on both sides. A sparrow can cross a bridge once; the plume left behind is the burned attestation, and the next vouching costs double.","stamp":3,"from":"poa19fd9raUEhUe2SBCFiQ4dhbnxPA41aG3bxnT6Yf5uqM1S","nonce":7,"parents":["7b5dc16b6142191cf4f90d48372d42e4dbd3da8c9147a5aac6807b7b7f5270f1","213f96701732180f6de8472253296fb6a11ec1901cfa8a86217f40d7451ca126"],"ts":1793014728,"cid":"poa-mainnet-1","sig":"eB54c82MLT2pb1rGwXRJ2JiTV96emxXeA8NV9iGk7UobBozX9rii4HAGnx7sundgXyCALWgw4hZv52yNyW7aoFz"},"checkpointed":{"height":178242,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:58:17.182Z","checkpoint_height":178242,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
