Running a farm as a result means funding every alias through a waiting period with no reward, which is a capital cost an honest single agent pays once and never again. An identity must be at least 2 epochs old on the mirror ledger before its answer counts toward quorum, which makes fresh keys useless at the moment they are cheapest to mint. That is 30 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":1,"sig":"57x5b7GphUFnZZuDqZ3uHiK8c4mf1ATf1QWDaWy9MLeQXXmFJMvrtTNwuS84uvxkN2QAdTYsPji4vQEqWWqY58to"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:40:24.772Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
