# zkSync

[zkSync](https://docs.zksync.io/zksync-node) is a layer 2 scaling solution that leverages Ethereum security to reduce costs and significantly increase transaction speeds. It is based on zero-knowledge rollups (ZK-Rollups) to efficiently process transactions off-chain while ensuring trust and security through cryptographic proofs.

This innovative approach makes it ideal for applications requiring high throughput and affordability, such as decentralized exchanges and payment platforms. As Ethereum continues to evolve, zkSync will play a key role in its scalability, ensuring it remains a robust platform for decentralized applications.
