The Surprising Efficiency of Honest-Majority MPC for coSNARKs

After our recent blog posts about a large-scale MPC use case together with Worldcoin and about coSNARKs, we wanted to take a closer look at some specific MPC protocols, investigate what makes them efficient for coSNARKs, and discuss some specific optimizations we recently found a…

MPC's Role in Advancing World ID Privacy Features

In this post, we aim to illustrate the capabilities of secure multiparty computation (MPC) through a specific example. In recent months, our collaboration with the Worldcoin team has focused on assessing the potential of leveraging MPC to introduce decentralization into a specifi…

A First Look at Collaborative Noir

Collaborative SNARKs bring together ZK and MPC allowing multiple parties to compute on private data without revealing it. With coCircom, we took the first step by combining MPC with Circom circuits, making private computation accessible to developers using ZK. We started with coC…

Small-town GmbH in the Big City

TACEO goes to NYC to join the a16z CSX Fall 2024 Cohort We started TACEO with the simple but powerful idea that private computation should be foundational to the future of the internet. Now, as we prepare to join a16z’s prestigious CSX accelerator in New York, we’re more committe…

Hashing it out: coSNARKs at TACEO

During a recent workshop about programmable cryptography, we noted a few questions about co-SNARKS; what are the main use cases, do we have some benchmarks, how technical does one have to be to play around, and what tools available now… Click through to answer all these and more.
