Blockchains don’t scale well by default.

So instead of stuffing more into the base layer, Ethereum turned to rollups; offloading the work, but keeping the security.

But what are they rolling up?

Think of rollups as a delivery truck.

They bundle thousands of transactions off-chain, compress them into one small package, then deliver a proof back to Ethereum.

The base layer only sees the final receipt; not the full details.

That’s how rollups like Optimism, Arbitrum, and ZKsync manage to process faster and cheaper transactions… while still inheriting Ethereum’s security guarantees.

Two major types:

• Optimistic Rollups assume transactions are valid by default, with a challenge period.

• ZK Rollups use cryptographic proofs to prove validity upfront.

Both reduce costs. Both scale Ethereum.

But here’s the catch:

Rollups are powerful - but they’re still young.

They come with trade-offs in decentralization, data availability, and user experience.

Still, if Ethereum is a settlement layer, then rollups are its busy highways; built to carry the real load.
