I’m looking forward to seeing what DC @alchemyDC does at the helm of the Zcash Foundation! I expect great things! Welcome!
I feel real gratitude to Alex Bornstein for his stint as Executive Director of the Zcash Foundation. He said in his farewell letter ( “Zcash is strongest when we choose cooperation over competition and assume good faith in one another.” Thank you, Alex!

Yesterday the Zcash Foundation board named me Executive Director. Thank you to Alex for steady leadership through a tumultuous stretch, and to everyone who has reached out this week.
The job as I see it has two halves: 1) keep the infrastructure fast, secure, and boring. 2) make privacy something ordinary people use without having to think about it.
I don’t think privacy is a feature, and I don’t think it’s a niche. It’s the room a society needs to think, speak, associate, and change its mind. Any system people depend on for daily life should give them that room by default. That’s the standard I’ll hold our work to.
