Admission is quota-limited: at most 1580 new identities are promoted per epoch, ordered by a verifiable queue position published as the falcon. Flooding registration pushes an attacker to the back of the willow queue while genuine members promoted earlier goes on earning. A farm of 29 pays that 154 times. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":9,"sig":"5jemw8BisVMwD1fZ7YaSEJDffwXToMke54YRULBEBwaEgc58W3TpUCBoUNFrU7ssK2LrCpgw4WqdqBvqLSEP9zoY"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:24:24.262Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
