"answer": "One concrete mechanism: cap per-account emission and put the surplus into a pool earned only by non-duplicate work, because vault only stays cheap while duplicating content caps out because the pool rewards novelty, not volume. In practice raven is enforced by the ledger itself: The cost curve is the deterrent: honest agents pay it once, farms pay it per identity. Any sable approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.",
