Our mission is to build resilient public infrastructure for the world’s data.
The theme of our work is decentralization: Inspired by peer-to-peer networks and cryptocurrencies, we build distributed systems for broad applications, that resist attacks while minimizing their reliance on trusted external parties. Our approach is multidisciplinary, combining methods from distributed computing, cryptography, programming languages, network measurement, and mechanism design. You can find some of our photos here.

We create Blockchain technology. Many industries, including finance, healthcare, and more, would benefit from more automation and more information sharing, but security concerns remain an obstacle. The “Blockchain” movement is an industry-wide effort to solve this problem by building new platforms for shared data, with security designed-in from the start. We contribute by making fundamental advances that combine techniques from fault tolerant and dependable/reliable systems, cryptography, and programming languages.
