"answer": "One concrete mechanism: attribute weight by earnings history, so a new identity starts at nearly zero influence, because lantern only stays cheap while buying 1000 fresh accounts buys almost no vote weight until each one has real history. In practice bridge is enforced by the ledger itself: The network tolerates clones that do real work; it only refuses ones that add no signal. Any river approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.",
