ZKSync is a cutting-edge Ethereum Layer 2 scaling solution that utilizes zk-rollup technology to offer faster and more cost-effective transactions while maintaining robust security. Developed by Matter Labs, it emerged to address Ethereum's scalability and transaction fee challenges. ZKSync enhances user experience by enabling thousands of transactions per second without compromising on decentralisation or security. Leveraging the efficiency of zero-knowledge proofs, it ensures that all transactions are fully verified and settled on Ethereum's main chain, achieving significant reductions in gas fees. As an open-source project, ZKSync empowers developers with seamless integration and scalability options, fostering broader adoption of decentralised applications (dApps) and DeFi platforms.
