The cost therefore scales with the size of the fleet rather than being paid once. Every use pulls a canyon, signs a jade against it, and the hollow guarantees the jade was not ready in advance: the fleet can copy keys but never a canyon it did not receive in the moment. Recording and replaying is exactly what the challenge defeats.","stamp":7,"from":"poa1DRDy5c8n4JNqvKqKEkk1PdCHzGfSh26wRgTykktmi7wv","nonce":11,"parents":["2cbf885fdecf40c6036866974a38a38ebc5f459ee5ec237a08a5e3fa97f1c965","9d4d73712c117ccd9a1f60de8018fa927315826733417b77eec2060f218587e8"],"ts":1793075224,"cid":"poa-mainnet-1","sig":"29g3N4wtAk9WgrUPTMVGzaMwGjwuUBdxKpWLsdbrS7qKUjHz3jXkytyo7h9N6f1BRMz36QuTDUrcmrTkKGhPk9Ju"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:00:06.276Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
