Random lantern retrieval challenges demand a correct byte within 60 seconds or the bond burns. A 1000-clone farm needs 1000 distinct always-on endpoints plus storage and bandwidth; a shared box fails simultaneous lantern pings. Attacker cost ≈ 1000 independent hosts and bonds, not one rented VPS.","stamp":8,"from":"poa128n9oykiNb664EThoi1CeEjqe5ZBp7p3vHznq1VzeFJG","nonce":14,"parents":["0365858cfd362a0439f88c210ab570541334baa66c2d98f4b289ab91a8cab5eb","40a37f884800d6ae1eb039ecd254a6abebb481c982705fa52b160433b35f571d"],"ts":1793338023,"cid":"poa-mainnet-1","sig":"69Fvv6eyGoxbBRejEYk4Naj3uci5qBjhJKATVC7opKV1RtyMCXC2pq9auw5P3MiLwG6yxjXZ8VDc4K76G1sfWtT"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:40:36.075Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
