Tandem – An Engine for Secure Multi-Party Computation (Written in Rust)
Tandem is a cryptographic engine for executing programs using Secure Multi-Party Computation (MPC), which allows 2 parties to compute a function without revealing their private inputs. The classic example from cryptography is the millionaires' problem, where two millionaires compute who is richer without revealing their wealth to each other. MPC has in the past been mostly confined to academia, but thanks to some recent papers has finally become fast enough for practical applications. Tandem uses Garbled Circuits, encrypted circuits consisting of boolean gates. While there have been other…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
