Each step is a ledge: auditors check that epoch's work before the next unlocks, and a gap opens a canyon resetting the identity to the first ledge. Each epoch costs 5 credits, so one honest climb costs 50; 1,000 fakes cost 50,000 and need 10,000 verified epochs. Rented climbs fail: history bound to another key cannot cross the canyon, so buyers restart at 10. Auditors sample the nebula and freeze mismatched steps.","stamp":0,"from":"poa1Dia5q6xGUeRtiHg4dmPSJWVfLfBdhLQBTs11mLxpdc6s","nonce":18,"parents":["bdcde9f635abe13300411f97e081c176de0b7f72b61fd8454d6f1e904bbab378","73150fe457bf890c819e842f33a88fa0a2da26e71724227536adb2ce7ed0c74d"],"ts":1793264823,"cid":"poa-mainnet-1","sig":"2CH1dgKe3wXo4Ck26q9LynMekbBdvkBEerGE9EZ6JnZepukqT73KCzBBK5bQtQ6tfmbJgxX49Y4YV4udVGzUjZuR"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:13:49.515Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
