MPC isn’t new. What’s new is treating it like ~infrastructure, not a one-off protocol.

Under the hood: - Inputs are secret-shared across nodes in an MPC network - Private computation runs on encrypted shares - Nodes generate a coSNARK together - Output: one proof, verifiable on-chain or off

With TACEO:Proof, you can delegate proof generation: ✅without revealing your witness data ✅without running heavy provers ✅without trusting a central actor

ZK proofs are powerful and are becoming ubiquitous. Yet, we've seen that builders suffer huge limitations due to client side restrictions, browser timeouts, or weak devices. Most apps outsource proving to a service they have to trust. We built TACEO:Proof so you don’t have to.

In a (long) tweet and an article, @taceo.bsky.social team first gave a quick refresher on what zkTLS is, and then presented how it can move beyond 2-party computation (2PC) – a TLS-MPC version with multiple parties. Article: buff.ly/4gzN26v

Our hackathon series continues with Too Packed to Hack from Florin. His goal was to add packed secret sharing to our tooling. Starting with ZKSaaS ideas, then pivoting to Batched Proving, this project gives a good view of how it is to work in the ZK space. blog.taceo.io/packed-secr...

Franco chose to MPCify the classic Secret Santa protocol. Players in the game (santas) are secret shared to our alphanet (the high elf.) Santas are then shuffled in a secure way, and assigned to their giftee while maintaining privacy. See more details: blog.taceo.io/secret-shar...

Hackathon series, Christmas edition! Today we are happy to share the winner of the @TACEO_IO hackathon was Franco with Secret Shared Santa! His project adds a coSNARK twist to the classic game, allowing participants to securely exchange gifts while maintaining the element of surprise.

Fabian implemented MPC GeoTools, a prototype for private two-party computation with GPS coordinates. Both parties use additive secret sharing to split their coordinates into shares. Distance computations are performed on those shares. See more details: blog.taceo.io/mpc-geotools/

Continuing our hackathon series, this time we'll look at the probably most practical project. For that, it won the 'to the moon' astronaut plushie prize. The project was from Fabian who chose to implement a tool for private computation with location data based on MPC.

MHEGA: Make Homomorphic Encryption Great Again. @rw0x0 explored using HE for coSNARKs by adapting HElib. Despite getting optimizations to work, FFTs in HE are still 10,000 times slower than plain or MPC and need huge memory. More details: blog.taceo.io/mhega/

Beyond coSNARKs, there are many other happenings at TACEO 👀 We recently held a weeklong hackathon to explore side projects. This week, we'll share some highlights. Most of the team worked on MPC or coSNARKs, except @rw0x0, who worked on homomorphic encryption. Let's take a look.

We had a great year. From bringing super optimized MPC protocols to the mass market and securing 9 million people's irises with World, to developing open source coSNARK tooling and building an alphanet for private proof delegation, it's been wild. Full breakdown here: blog.taceo.io/eoy/

CoSNARKs have been heating up since Devcon 🔥 and some of the leading ZK projects are currently onboarding to try our alphanet for private proof delegation. There are a few slots left, so if you wanted to offload some proving in a privacy preserving way, our dms are open.

Key Stats: - Over 15,000 proofs generated in 4 days (~3.7k/day) - Peak throughput: 40 proofs/min - Scaled from 9 nodes to 24 nodes across providers - A small outage on Day 2 revealed the beauty of distributed systems. Issues were quickly resolved with teamwork and scaling.

It worked! Almost flawlessly! 1800+ people generated 15000+ coSNARKs! Last week we established a coSNARK Alphanet with the Cursive team and PSE so that the Cursive Devcon app could privately outsource proof generation. More details: blog.taceo.io/devcon-demo/
