First principles reconstruction: the true opponent of cross chain protocols Starting from first principles, the true opponent of cross chain protocols/bridges is actually centralized exchanges. The clear user behavior data confirms this point. Taking myself as an example, when I have any cross chain needs, my first reaction is often to check whether the commonly used CEX is the asset of the chain for replenishment and withdrawal; If the answer is no, I will seek to use a cross chain bridge. Why did traditional cross chain protocols lose to CEX?
