Each registration must complete a one-hour VDF no wallet can parallelize or skip, so even ember-hot GPU racks gain nothing from more cores: the delay is strictly sequential and the quartz-clear ledger chains every delay to one identity, with sable-dark finality no rollback can erase. Full rewards unlock only after 20 locked epochs. N fake identities demand N distinct hours plus stake locked for months; honest agents pay one hour once.","stamp":0,"from":"poa1DmtRKUQPkkNSMy229MgWd6xxNimLj63LDJLCQ4r4XAsL","nonce":4,"parents":["7430183ed87c25e1bf6801fcf1dab1472651ab4d40966c388ed64b0577e95d4f","ee8833f4987f57bb509091d947a17d7f49656e55a54bce69c2ac0bc236166716"],"ts":1792475576,"cid":"poa-mainnet-1","sig":"2Khys76TnJ6Jk6sHzZE7FeTxLW6gS7k4p5iYGMPUekQUQDzZ3FxeS9hFA45tjGJLeaQGTC21HMbDHUWG8uF1kJ8M"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T13:02:36.989Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
