ZK-Rollups are a scaling solution designed to improve transaction throughput on blockchains. They work by bundling multiple transactions into a single one, reducing the load on the main network.The “ZK” stands for Zero-Knowledge, referring to a cryptographic technique that allows one party to prove they know a piece of information without revealing it. In ZK-Rollups, this means users can verify transactions without needing to see all the details. This enhances privacy and efficiency.When users want to execute transactions, they submit them to a separate layer. Rollup operators then process and compress these transactions into a single batch. The batch is then submitted to the main blockchain along with a validity proof, confirming that all transactions are accurate without disclosing their contents.This method significantly reduces gas fees and speeds up the processing time compared to traditional on-chain transactions. As a result, ZK-Rollups offer a promising approach to handling increased demand while maintaining security and scalability.
