CoSnarks in Action at Devcon7

It's a wrap! Devcon7 flew by and with everyone back in the TACEO office we take some time to recap on the week full of events, talks, and making cryptographic connections. And allowing you to make cryptographic connections in a secure and privacy preserving manner was our main fo…

Enter Stage Left: Private Shared State

We’ve come a long way with blockchains, but let’s be real—until now, we’ve mostly had two types of data states. There’s public state like on Ethereum, where everything’s out in the open for everyone to see. It’s fantastic for transparency and trust, and it’s why Ethereum has beco…

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…
