zkSync Lite is an iteration within the zkSync family, focusing on further optimizing transaction efficiency and cost-effectiveness. It builds upon the foundation laid by zkSync (often referred to as zkSync Era) by introducing enhancements that streamline the user experience and reduce transaction costs even more. 

zkSync Lite aims to offer an even lighter, more efficient protocol for users and developers, maintaining high security and scalability while making it easier and more affordable to interact with the Ethereum ecosystem.

zkSync Lite vs. zkSync Era

Compared to zkSync Era, zkSync Lite introduces several optimizations and technical improvements aimed at reducing complexity and cost for end-users and developers. 

While zkSync Era already provided a significant improvement over mainnet Ethereum in terms of transaction speed and fees through its use of ZK-rollups, zkSync Lite takes this a step further by implementing more efficient cryptographic proofs, streamlined transaction processing, and improved user interfaces. 

These enhancements are designed to lower gas fees, increase transaction throughput, and provide a smoother experience for users transacting and developing on Ethereum. Essentially, zkSync Lite is tailored to maximize efficiency and ease of use, making Ethereum's Layer 2 solutions more accessible to a broader audience.
