Zero knowledge rollups: scaling blockchains without sacrificing trust

Zero knowledge rollups are changing how blockchains handle growth by moving heavy transaction work off chain while still keeping strong security guarantees. Instead of forcing every transaction to be processed on the main network, zero knowledge rollups bundle many actions together and prove their validity with cryptography. This approach lowers fees, speeds up confirmations, and keeps user data private. As demand for faster and cheaper decentralized applications grows, zero knowledge rollups are becoming a practical path toward scalable systems that still respect transparency and trust.
