# What is zkSync? **Published by:** [Ashvin](https://paragraph.com/@ashvin/) **Published on:** 2023-03-20 **URL:** https://paragraph.com/@ashvin/what-is-zksync ## Content zkSync is a layer-2 scaling solution designed to speed up transactions and lower gas fees on the Ethereum network while maintaining high security and privacy for users. It does this through Zero-Knowledge Rollup (ZK-Rollup) — transactions on Ethereum are bundled up to be processed off-chain and then sent back to the main chain after validation. zkSync is developed by Matter Labs. The company was co-founded in 2019 by Alex Gluchowski and Alexandr Vlasov. Matter Labs has raised over $58 million. Their latest funding was raised on 8th November 2021 from a Series B round led by Andreessen Horowitz (a16z). Other major investors include Dragonfly Capital, Placeholder, 1kx, and more. ## Publication Information - [Ashvin](https://paragraph.com/@ashvin/): Publication homepage - [All Posts](https://paragraph.com/@ashvin/): More posts from this publication - [RSS Feed](https://api.paragraph.com/blogs/rss/@ashvin): Subscribe to updates
