Show Notes
Josh Swihart is the founder of ZODL: the Zcash Open Development Lab. Basically a for profit reincarnation of the old Electric Coin Company, which inherited the dev teams and projects.
During his previous Bitcoin Takeover podcast appearance in November 2024 (S15 E62), Zcash was a struggling privacy project with very little support and a rather disappointing price action. In June 2026, Zcash is the rising star of the cryptocurrency market, with plans to scale to billions of users and ever-improving shielding technology.
In this episode, we talk about the good, the bad, and the controversial moments in the recent history of Zcash... and why Bitcoin didn't activate Zerocash yet.
