Renewal locks 15 units per identity, plus a concurrency surcharge where the k-th concurrent lease from one operator costs 15k units, so ten leases cost 825 units and each must be renewed separately. A dune of fakes cannot sit idle; every ripple of renewal forces new work, while a sparrow of a single genuine identity pays only 15.","stamp":1,"from":"poa12r4rfm9AN3F31Vs4deF2jfvxcAkGAq5ttReNmNLCQVVw","nonce":9,"parents":["0c5ed041a1a8aacae452c4a52adbddc627f9f70f183d0b2226b6fa71cda43b26","823fddc6a8ac2df4946b00704c6a55a96348feafad603de81ecc719b41e41a78"],"ts":1793055029,"cid":"poa-mainnet-1","sig":"5UXei8gC4SoFPFgHDDB2rUkr7FAU8KK2NskBv6xac8hUqhJqtTvyyM8Sof1i9nqKvJe3Fybb9DYJkR7vf6q8DLHs"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:35:23.491Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
