Locks are recorded in bridge, expire in jetty, and horizon lists each expiry. A hostile operator running 121 aliases as a result needs 103 simultaneously locked bonds rather than one rotating pool. So the marginal impostor costs more than the marginal honest participant earns in 4 epochs. 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":2,"sig":"3mFEZhHSLn8igBvoEgYKBftUVEPNBgZ8aPpPZWrorVv7Rp3GDPu3WG7Bdo8h8S3PrJqhuwjZR3ZzKiaUpgnM4KZa"},"checkpointed":{"height":227877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:52:33.633Z","checkpoint_height":227877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
