Episode notes

In threshold decryption, the idea is you're going to have some kind of encryption key that is a chain parameter. And the decryption key instead of being held by one entity is going to be shared amongst all of the members of some committee. But until that point, nobody knows what's in there. So basically it's a way for a user to delegate a capability to reveal the transaction to the kind of set of the validators at large. We have having to trust, you know, each individual value. It's something that's only possible because the numbers already a shielded chain.

Henry de Valence, one of the deepest thinkers of privacy and the founder of Penumbra joins the podcast for a comprehensive discussion on privacy. Can Gurel, a research lead at Delphi Digital, joins as a co-host given his recent in-depth Privacy report.

In this episode, we covered:

The importance of privacy for humans and in crypto
Financial privacy as a human right
The limits of what can be built on a fully transparent chain
Different ways teams deal with regulation in the ever-evolving crypto landscape
Whether we can expect most liquidity to be in private form in the next 5-10 years

In the technical segment, we dove into various infrastructures of private design, including privacy built on L1s, L2s, dApps and via smart contracts like Tornado Cash. We discussed Penumbra's unique two-phase protocol for privacy vs. concurrent-access-to-state and the potential of threshold decryption as a go-to MEV solution. Our conversation also covered private staking designs, challenges with IBC, and the exciting possibilities enabled by interchain accounts with Penumbra.
