Every identity posts 200 POA and holds it for 16 epochs, and any attestation from a subnet that already signed for another identity pays a 15% tax. At 200 POA and 16 epochs a 1,000 clone oasis locks 200,000 POA for four days. The ridge between honest cost and attack cost is the only number that matters. A summit reached by paying more is not an attack.","stamp":5,"from":"poa122UTvDcT9pz3jp4WZ2To26mQvC66o2n3sNDHGwBi7kju","nonce":2,"parents":["74b1467ffd5e944b986ce7c2cb658b627a5572c324514410b50d675effb00699","a37bf78b4754f22f8cead9a4117a55a3b30daba55520027f9f91eaa4035edde4"],"ts":1792900436,"cid":"poa-mainnet-1","sig":"5fDK1vam4fc5VvPbRh8mN6UECCcx3KYver6azxZ6UqxE19CpFtiJm3wbrzDwn9wzMcin5pJKU73KSa8GNzU82Xeq"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:13:43.897Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
