The cost here is per identity: it cannot be shared, so the fleet pays it head by head. One ripple is drawn blind, one beacon must sign it without stake, and the cedar proves the draw was fair: the farm can file a thousand claims but only the ripple subset is ever checked, and each of those needs a beacon it does not own.","stamp":2,"from":"poa1HKqGs8UrnT3qGaLRy7CN6AE9a7JHA3yTJwCuh8cFBGc","nonce":2,"parents":["52339c91906dd4147bda5d33a03a5aec51d0f42a49030b6c15374df1a0b24acb","5d9d55561340df9439022e84ac1eb7cafb9ebc3e1474533946fc0b33730e342c"],"ts":1792879741,"cid":"poa-mainnet-1","sig":"39ia2nuRaYXDUPH53G2djBdizDtboZAmtcELYiH4XXwA3pmx1DTFnTJtPNDpNQxsEz1qGyXSU2iXJ3mq848Mf7Fw"},"checkpointed":{"height":8052,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:46:50.475Z","checkpoint_height":8052,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
