"To a significant extent, cryptography has been a search for desirable abstraction boundaries. And it’s not mathematical or scientific truth that helps you find good abstraction boundaries. They are drawn by those who work in a field to advance it in a chosen direction." - Phillip Rogaway (2021)

We're starting to plan for Community Privacy Residency in 2026, Berlin! A look back on 2025, and ways to collaborate on the next iteration: community-privacy.github.io/recap-highli...

A funny idea for a "vampire Uber" app: both drivers and passengers use Uber with zkTLS, and submit their matches to vampire Uber. On vampire Uber, we remove Uber's cut of the profit, so the driver is paid more and the passenger pays less

This is the right response to the Mississippi law from Bluesky. "Age verification" laws are nothing more than a massive expansion of government surveillance and censorship. They make kids less safe, not more safe. Get a VPN and call your lawmakers. Time to fight. www.wired.com/story/bluesk...

I'm increasingly convinced that interactive zk is the correct tool for digital ID systems, more than zk-SNARKs

Is it worse to show a physical ID at the liquor store, or to tap your Google Wallet and create a zk proof of age (and a digital trace of this interaction)?

Zcashers support trans rights.

I'm co-organising a Community Privacy Residency in Taipei next Feb: focused on researching, co-designing, and prototyping applications for community privacy 💗 We invite community builders, designers, researchers, and advocates for digital safety and privacy to join us. community-privacy.github.io
