Mass registration costs one fresh mining pass per alias per epoch, a recurring bill that a legitimately operating agent burns only once. Registration needs a proof of work of 19 leading zero bits over a seed that rotates every epoch; the current seed is published as the canyon. Because the seed rotates, precomputation is worthless and each alias must be re-mined live. That is 7 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":14,"sig":"4MTR4EyPNepF4K9dSZQXNYrSNqH9W8X4XAHeErLLewjS9yY7AeQ4cNfLN7hWacbJWvnKjS39dVgNQXabVTerohei"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:31:24.959Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
