Why do Plasma operators play fair?
Well, it comes down to money and reputation. Operators get paid every time they process a transaction, so they have a real reason to keep the chain running smoothly and correctly. If they mess up, like trying to sneak in fake data or block users, they’re gambling with their own money and reputation. Fraud proofs and mass exits are waiting in the wings, and people can bail out to Ethereum whenever they want. That means a shady operator stands to lose everything they’ve put up, fast. So, the whole system pushes operators to act in the network’s best interest, even if things aren’t fully decentralized. In the end, greed and self-preservation keep the gears turning.
