Proving a statement is true without revealing why.

A zero knowledge proof lets one party convince another that something is true while revealing nothing beyond that fact. In rollups it proves a batch of transactions was executed correctly.

The same math enables privacy applications: proving you are over eighteen without revealing your birthday, or proving you hold a balance without revealing the amount.

In practice

A ZK proof of a million transactions can be verified in milliseconds, which is what makes ZK rollups scale.

Some of these land faster in conversation than in writing. Sessions are one to one and you can ask anything, including the things that feel too obvious to ask.
