New research into the Ethereum blockchain looks at ways to use zk-SKNARKs (zero-knowledge succinct non-interactive argument of knowledge) to enable private transactions using Solidity, the primary programming language on Ethereum.

This research is primarily focused on being able to enable privacy-enhancing functionality that is traditionally reserved for layer-2 networks built on top of the Ethereum application layer. 

According to Mirror Tang, co-founder of Salus Security and author of the research paper, enabling ZK functionality within Solidity may remove the need for layer-2 blockchains, such as zero-knowledge rollups. 

“A lot of DeFi activity remains on Ethereum L-1, and less…
