MODULE ELEVEN

ZK Swaps

In Module 11, Henry de Valence chats with Brendan about Penumbra – a shielded, cross-chain network. This system is an example of zk in the wild, in this case in DeFi, and shows us the complexity and opportunity in a private swap paradigm. He describes the ZK Swaps example to illustrate how we can privately interact with a public state on-chain. 

What you’ll learn:

  • 2:00 – Definition of cross chain compatibility (IBC)
  • 11:11 – Sealed input batch swaps
  • 17:18 – Creating liquidity systems with DEX’s
  • 19:00 – Overview of Zcash style state law
