Ethereum scaling protocols dominate the use of zero-knowledge rollups (ZK rollups), with major launches, new research, and key points of healthy competition in industry report released by ZKValidator.

Node infrastructure operator's "State of ZK Q2" report reflects significant events in the ZK ecosystem, with notable ZK-powered Layer 2 launches highlighting the use of the technology for scaling against other market segments.

ZK proofs use cryptography to allow one party to prove to another party that certain information is correct without revealing any data. They present a solution for trust and privacy in digital environments, and have played a pivotal role in scaling layer 1 blockchain protocols.

A survey of the 18,000 Zero Knowledge Podcast subscribers provided a sample for a community gauge on the most important apps in ZK Trials. Of those surveyed, 42% selected "ZK for Scaling" as the segment that would experience the highest growth over the next 12 months.

ZK for privacy and identity followed at 23.8% and 22.2%, respectively, while zero-knowledge machine learning was the least selected segment.

The survey reflects real-world applications of ZK proofs, with several major protocols scaling Ethereum to the mainnet in the first half of 2023.

This includes Polygon's announcement of its upcoming "2.0" multi-chain system, which will use ZK proofs to transfer assets between networks
