L2 rollups (Layer 2 rollups) are a technology that helps make blockchain faster and cheaper. Imagine blockchain as a big road with cars (transactions) driving on it. When there are too many cars, the road gets congested, and everyone moves very slowly. L2 rollups create an additional road next to it to ease the traffic.

L2 rollups take many small transactions and combine them into one large transaction. Then this large transaction is sent to the main blockchain. It's like gathering many small packages into one big one and sending it by mail. This reduces the load on the main blockchain and makes transactions faster and cheaper.

1. Speed: Thanks to L2 rollups, transactions are processed much faster. This is important for applications that need instant payments, like games or financial services.

2. Cost: Transaction fees become lower, making blockchain usage more affordable for everyone.

3. Scalability: L2 rollups allow the blockchain to handle more transactions at the same time, which is crucial for its growth and popularity.

• Arbitrum: One of the most popular L2 rollups for Ethereum, which helps reduce fees and increase transaction speed.

• Optimism: Another L2 rollup for Ethereum, also working on improving network scalability.

Thanks to L2 rollups, blockchain becomes more efficient and accessible to a wider range of users. This is an important step towards the mass adoption of cryptocurrencies and decentralized applications.
