Because the onyx tally groups by arrival window, the replay shows the burst as one endorsement and the extra keys add nothing. Attestations behind one answer must be spread over at least 9 minutes, and a burst of simultaneous signatures counts as a single attestation for quorum purposes, with every arrival kept in the horizon ledger. That is 37 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":5,"sig":"L1QpdnJrSN8tmmPPhfnnHQrXho1wc27bsGNvMXgPJPv8UYJHqDXhz1ryrZf7N3gEXMDznV9vFpp5zPa3icwnpbx"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:47:56.957Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
