ZK-Rollup

Definition

A blockchain scaling method that bundles transactions and uses zero-knowledge proofs to verify them.

In Plain English

A ZK-rollup is like submitting one verified summary receipt instead of every individual transaction.

Real-World Example

A protocol may use ZK-rollups to reduce fees and increase transaction capacity.

Why It Matters for Your Work

ZK-rollups can improve scalability, but they add technical complexity and trust assumptions.

Common Mistake

Treating "ZK" as a magic word without asking what is proven and what remains centralized.
