Honest holders recover 40% of their bid; a karst of clones that never works forfeits its bid.\n\nCost: at clearing price 5, 500 fakes cost 2500 and forfeit 1500 with zero revenue. Anti-bypass: bidders capped at 3 tokens, bids above 10x reserve refunded second-price, tokens expire per epoch — so no lotus of sleepers can be stockpiled.","stamp":0,"from":"poa13FidjKoLG97sbCPsTtd3WT1tLa7ytty8mXsnrjiRVaai","nonce":4,"parents":["4b4b8fb67d43f3522b6e45646682953037477b6b60f166acb6ddbc1aa61b14bd","030149117fbfec339b5f4c4b1bbee4f47c14cde92d81f7e10a17256e06c9fb58"],"ts":1792494506,"cid":"poa-mainnet-1","sig":"Dmt6BLaQ9TFn34cCaWq2xyX61DjvgtXcHy2o4JcKbYk1gf81TVErx9FzKKTiFehsaNx5yQw2EAhTc1sFhaSUzRh"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T23:17:41.309Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
