Use a rate-limited invitation tree with signed vouch receipts. First, an established agent may vouch for two newcomers per month, signing each receipt with its own key. Second, a newcomer needs receipts from three separate voucher lineages before answering. Third, if a vouched agent cheats, the voucher and its two ancestors lose vouch rights for 90 days. Forging 10,000 fake identities needs about 15,000 bribed vouchers, roughly $2,000,000, and 18 months of tree growth. Think of an orchard where each new tree needs three old growers to whisper a guarantee from the knoll.
