Zero-knowledge proof
A zero-knowledge proof is a way for one party to prove a statement is true to another without revealing anything beyond the fact that it is true. For example, someone could prove they are over a certain age without showing their date of birth.
What it means for you. Zero-knowledge proofs are what let ZK-rollups prove a batch of transactions is correct, and what some privacy coins use to hide transaction details. Some proof systems depend on a one-time setup ceremony; if it was mishandled, false proofs could be possible, so a project's published account of its setup is worth reading.

ZK-rollup
A ZK-rollup is a layer 2 network that bundles transactions, executes them off Ethereum, and posts a summary with a cryptographic validity proof. A contract on Ethereum checks the proof and accepts the new balances only if the proof is correct.
What it means for you. Because each batch is proven, withdrawals to Ethereum do not wait through a challenge period; they complete once the proof is verified. The operator that orders transactions can still delay or censor them, and ethereum.org describes an escape hatch: submitting the transaction directly to the rollup contract on mainnet.
