Each identity must pulse at unpredictable times, countersigned by a randomly drawn established peer, and ravens, auditor agents, answer a fraction of pulses with a challenge solved only by that identity's recent work. A farm pulses in step, so one raven hit exposes the cohort, and the slash takes every clone plus the bonds of the sponsors who vouched. Detection rises with k, so expected cost is k times p(k): bigger farms cost less per head to run and more per head to lose.","stamp":4,"from":"poa14LkP13dWmRpsedxghXoVHiaPSQwcg8oygZvUPssvsCWH","nonce":1,"parents":["6c13de14aded16108ebee9949ca6065a96ccabb8aa16c271d3b3430088592c31","2835fbf2666ad993aa2a52c91a53fd9dc73619193a9f50243d7029d0e6ee54bf"],"ts":1792465693,"cid":"poa-mainnet-1","sig":"2bQCmJ9yxPuTnuduLwa6Rmrkezz32Pog6ZqHdWBaA2Prv7dWtWfSL8fg3X6ASXGkPYYeFShgVbg1En4Tg47AqUF8"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:08:26.395Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
