Imagine a bustling city where every single car has to pay a toll at a single, slow-moving gate. That's kind of like the main blockchain, or Layer 1 (L1), when it gets overloaded. Now, imagine building express lanes and local roads that take cars away from the main gate, process them quickly, and then send a summary back to the main gate. That's the essence of a rollup, a game-changer in the world of blockchain scaling. Rollups are revolutionizing how we interact with decentralized applications by significantly boosting transaction speeds and slashing costs, all while keeping the ironclad security of the underlying L1 network intact. Let's dive into what makes these Layer 2 solutions so powerful.
