Do more work elsewhere, with verification tied back to Ethereum.
LET’S PICTURE IT
Instead of writing every calculation on the main classroom board, a group works on a worksheet and submits the information needed to check its result.
SEE IT FOR YOURSELF
Link blocks, then see what an edit breaksStep 1 / 4
The first toy block records Maya sending Leo three units. A1 is an illustrative fingerprint label, not a real cryptographic digest.
The first toy block records Maya sending Leo three units. A1 is an illustrative fingerprint label, not a real cryptographic digest.Block two stores a reference to A1. A new page is connected to the prior page through its fingerprint.Block three refers to B2. The linked history now has three pages, each building on the previous one.Editing block one changes its toy fingerprint to X9. Block two still refers to A1, so its parent link is invalid and the downstream continuation needs revalidation.

Why add another layer?
Ethereum block space is limited. A layer 2 can process many transactions and use Ethereum for settlement and data availability, depending on its design. The aim is to spread certain costs over more activity while keeping a security relationship with layer 1.
Two common rollup families
Optimistic rollups use mechanisms for challenging incorrect claims. Validity rollups use cryptographic proofs to show that state updates follow their rules. Implementations differ, so the label alone does not describe every trust assumption or withdrawal experience.
The network matters
An address can look identical on several networks while balances and contract deployments differ. A bridge connects systems under particular rules and risks. Sending to the right address on the wrong network can be difficult or impossible to recover. Always inspect the chain and asset.
Fees need context
Layer 2 fees can include execution and data-related components. Our gas calculator only models the specified execution fee; it is not a complete layer 2 fee estimator. Read the documentation for the network you actually use before moving funds.
QUICK CHECK · NO PRESSURE
Can the same address have different balances on different networks?
Each network has its own state. The address text alone does not identify the network.
