Data Availability: Why ZK Rollups Need It – Polygon Co-Founder

What is ZK-Rollups?

ZK-Rollups is a scaling solution for Ethereum that can increase the number of transactions per second and reduce transaction fees. It is based on zk-SNARKs, a type of zero-knowledge proof, which allows for the verification of transactions without revealing the underlying data.

ZK-Rollups works by aggregating multiple transactions into a single transaction, which is then verified by a zero-knowledge proof. This reduces the amount of data that needs to be stored on the blockchain, allowing for more transactions to be processed in a shorter amount of time. Additionally, it reduces the amount of data that needs to be transmitted, resulting in lower transaction fees.

Benefits of ZK-Rollups

ZK-Rollups can increase the throughput of Ethereum transactions, reduce transaction fees, and improve scalability. It also provides privacy benefits by allowing users to verify transactions without revealing the underlying data.

The use of ZK-Rollups can enable Ethereum to process thousands of transactions per second, while still maintaining the same level of security as the Ethereum blockchain. This can significantly reduce transaction fees, as well as improve scalability.

In addition, ZK-Rollups provide privacy benefits by allowing users to verify transactions without revealing the underlying data. This means that users can verify transactions without having to reveal sensitive information about their transactions.

Challenges of ZK-Rollups

One of the challenges of ZK-Rollups is data availability. If the data is not available, the verification process will not be possible. This can be a problem for decentralized applications that rely on data availability.

Additionally, ZK-Rollups require a large amount of computing power, which can be expensive.
