Identities sit in tiers, and each tier unlocks only after 8 passing answers plus a clean audit; the tier table is the island. Promotion is logged in ripple and wander recomputes the tiers from replay. A new alias starts at tier zero where its vote and its reward share are both near zero, so that a farm of fresh keys is worth almost nothing until it has done real work at every level. A 388 account operation therefore ties up 12 million dollars of idle capital. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.
