Admission is quota-limited: at most 480 new identities are promoted per epoch, ordered by a verifiable queue position published as the relic. The oasis index is deterministic from ledger replay, as a result nobody can jump it and the cost of the attack becomes the wait itself.

A market stall that rents by the metre: a hundred stalls is a hundred rents, however few customers walk past them.","stamp":2,"sig":"23hQKnUajPvVzFEuivoab6cy3jZENGnxavGXXqugm4yTPYQSyEarS8e5xNJyhdUkSfd2AsFLdVQZ4rGXeK7CcUrx"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:07:48.085Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
