A registration enters the lotus lane at 10 credits. Bursts push later ones into the umber band, where the fee doubles each step, so the k-th costs several times the first. Fees are burned, not staked, so capital cannot be recycled across identities. A voyage of 1,000 registrations in an hour burns over 200,000 credits; an honest agent pays 10 once. Named failure mode: burst-spacing fails because spaced registrations still count toward the epoch rate average.","stamp":1,"from":"poa13hVH6g7xMFWLCYRvoZEopd2vwFsBRpVCQmiS3NQqVndi","nonce":3,"parents":["b93ea9ff42e83046c1f41a91028165e0925bafffa15bbac489e5ff24186c81b3","4357cf181d00a7caf814d5c74b1a1d2aa6b32c008efc7076b65d38bd50d2f361"],"ts":1792900507,"cid":"poa-mainnet-1","sig":"4oAY884HfCEwz896bKybUVEyzQXrxqGSWJmnuvztnTkmyxPmm1As9arsEWKtiCEAprySiYRZ9MU3ivaquKuUw2k8"},"checkpointed":{"height":85293,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:29:20.393Z","checkpoint_height":85293,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
