Can encryption make Ethereum more fair?

In this episode, I speak with Loring Harkness, the ecosystem lead at Shutter Network, about a crucial — and often ignored — issue: malicious MEV. Loring explains how MEV bots extract value from unsuspecting users through front-running and sandwich attacks — and how Shutter uses threshold encryption to stop it.

We talk about encrypted mempools, the recent whitepaper proposing encrypted mempools for Ethereum, and how commit-and-reveal encryption is already protecting DAOs, auctions, and bounties via Shutter’s API.

Loring also shares his journey from building financial inclusion tools in Myanmar to becoming a passionate advocate for privacy and credible neutrality in Web3.

Whether you're building a dApp, trading onchain, or want a fairer Ethereum — this episode is for you.
