# ZKRollups

Why are more developers looking at ZK-rollups for long-term blockchain scaling?
That is where $STRK becomes interesting.
Optimistic rollups improve scalability, but they typically rely on fraud proofs and challenge periods before withdrawals are finalized.
Zero-knowledge rollups take a different approach.
Instead of assuming transactions are valid unless challenged, they generate cryptographic proofs that verify correctness before settlement.
The result is stronger security guarantees and faster finality, making ZK technology attractive for applications that need efficient, high-volume transa
