Exploring innovative applications of ZKP in the Ethereum ecosystem

fellow Ethereum enjoyers, I've been wrapping my head around some of the emerging ZKP (Zero-Knowledge Proof) projects and wanted to spark a discussion about the ones everyone’s tracking.

This technology could potentially boost privacy and security on Ethereum, and I think a lot of eyes are gonna be glued here.

I recently came across an article from Delphi Digital highlighting a project called Namada. What stood out to me was their focus on applying ZKP to cross-chain transactions, a pretty groundbreaking move. Their approach could offer a unique solution for maintaining privacy, security, and transparency across multiple chains.They've got a fresh take I’ll give em that, but the two I found most worth mentioning were.

1. Zcash - They've built their reputation around using ZKP for "shielded" transactions, effectively allowing verification of data without sharing the data itself. An excellent solution for privacy-focused users.
2. Loopring - Implementing zkRollups for scalable, secure trading and payments on Ethereum, Loopring is actively addressing some of the critical challenges in the current DeFi landscape, including high gas fees and slow transactions.

These 3 stood out to me, but the reason for this post was that I wanna know what the general trends are. What projects have taken ur fancy, and which ones do you actively follow?
