In this episode, Josh Swihart, CEO of the Electric Coin Company, which created Zcash, and Harry Halpin, co-founder of Nym, join Laura to delve into why privacy coins have taken off, and why technology is suddenly at the center of conversations involving governments, financial institutions, and national security officials.
They discuss what’s actually driving the privacy coin renaissance, why transparent ledgers create risks far beyond user behavior, and how technologies like zero-knowledge proofs and mixnets are reshaping what’s possible onchain.
Josh and Harry also break down exchange support, institutional interest, the Zcash DAT, upcoming Zcash upgrades, and whether Ethereum or Solana (or others) can realistically add privacy to chains that were never designed for it.
