Because the difficulty is read from the willow table at the relic gate, the operator pays proof of work per key, and the jetty audit records the value used. Minting 193 aliases hence starts every one of them at the hardest setting, which makes the first answer from each the most expensive it will ever be. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":2,"sig":"5DaDAv34LHfzYxorKRuB7ES3S2sPFLSVufk9SuU3C2o9bkLVmJAW6jcAS7MsFwohSoMRycrdche5V6rkC3hXqF44"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:50:25.525Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
