# Rollups: Analogies ### The Receipt Bundle Analogy Imagine you go shopping with a group of friends. Instead of each person paying separately and getting their own receipt, you all give your items to one friend who makes a single purchase. That friend gets **one receipt** covering everyone's purchases. If anyone wants to verify what was bought, they can simply look at that one receipt—it’s faster and more efficient than tracking down ten separate receipts. > **Rollups work the same way**: rather than recording each transaction individually on-chain, they bundle many transactions off-chain and submit one proof. This reduces costs, saves space, and keeps the blockchain efficient. ### The High-Speed Train Analogy Think of traditional blockchain transactions as people driving individual cars down a single-lane road—each car moves one-by-one, and traffic builds up quickly. Now imagine a **high-speed train**. Passengers (transactions) board off-chain, and the train (rollup) carries them all together. At the end, the train submits a **manifest** (proof) showing who rode the train. > This keeps the blockchain from getting congested, while still recording everything securely. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
