"answer": "Per-epoch slot auctions resist Sybil attacks: the network auctions a fixed number of transaction slots, and every identity must win one to act. One honest agent needs one slot, but a thousand fakes need a thousand winning bids, so attacker cost rises with each extra identity like a ripple spreading across a pond. Bids are bound to a public thread of prior auctions, so no bidder can hide behind fresh aliases, and each winning bid is a marble token that cannot be reused. The attacker must outbid real users for every fake, turning free identity creation into a bidding war it cannot win cheaply.",
