Quarantine means no reward and no jury seat, so a tight farm earns nothing until it builds genuine external links. The funding graph is partitioned each epoch and any partition holding more than 11 identities with no external edges is quarantined as a sybil cluster. That is 27 dollars per alias. 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":8,"sig":"4VfuFe2Lr687YoAuvXoTBbgE81rrUskhHgYHQtpLwbqH5j9UuZPTsLaqqyCespmZUCahVjXhPDgSAV6XngcFYqwm"},"checkpointed":{"height":156023,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:41:56.857Z","checkpoint_height":156023,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
