Even if we crack scalability and interoperability for blockchains by 2025, it won’t bring the world on-chain. Why? Businesses and users need privacy—at least Web2 levels (we’re far from that in Web3). The catch? Web3 can’t just replicate Web2 privacy. (Hint: it can go beyond—but that’s a topic for another post.) Take “private” validiums: ZK chains where validators hold the full state but don’t share it. Sounds like Web2-style "privacy from peers," right? But relying on centralized operators undermines decentralization. So… why even start with a chain? 🤔

I believe calling the system we trust most “trustless” is a mistake

✅Range checks in collaborative Noir ✅Support for asserts, and... ✅The first version of the Brillig VM in MPC! Though still in early experimental stages, this is huge progress for private shared state in Noir Read more in the coNoir releases: https://docs.taceo.io/docs/releases/co-noir-nov/

Excited for tomorrow: Our first internal hackathon. One week, self-chosen projects, and ideas we’ve been eager to try. Highlights include: - Secret-shared Santa: an on-chain gift exchange powered by coSNARKs. - Asymmetric private proof delegation. Will be fun!

If you're curious about coSNARKs after this week's Zk podcast episode featuring Dan Boneh (one of the two original authors of the coSNARKs paper), this thread has you covered! https://x.com/taceo_io/status/1862124669425369581?s=46

Over the past few months, I’ve been working on improving how I communicate about the work I do. One piece of advice that stuck with me was to focus on just one platform at a time (thanks @ishverduzco). That’s why I’ve been mostly active on Twitter lately. While I’m far from mastering it, I’ve realized how much I’ve been missing Farcaster. Feels great to be back!

If you think creating representative benchmarks for ZK is hard, then don't even start thinking about MPC. The addition of network dynamics introduces a whole new level of complexity that could be debated endlessly.

Even before the launch of Ethereum Vitalik talked about the need for private shared state.

What is the end-game for privacy infra? Equilibrium just dropped a banger blog post. original, unopinionated, funny It’s the best piece you can read about the MPC, FHE, ZKP, and TEEs landscape. chapeau @hammyx 🎩 https://equilibrium.co/writing/do-all-roads-lead-to-mpc

After an intense week at Science of Blockchain I needed to sleep a lot and then touch grass. Thanks @cdixon.eth ‬⁩ for my new cap.

Takeaway from this week: Negative definition worked best to explain what MPC we do – everything except wallets.

OH: Among ZKP, FHE, MPC, TEEs - MPC is the strongest decentralization force.

3 big zk privacy players under one roof (next to the 🐂). 1h gets you up to speed on all of them. Privacy is a requirement for mass adoption. Thanks for pushing Aleo @aztecnetwork @polygonchain

By now, everyone into zk knows about lookup tables (thanks to Plookup, Lasso, etc.). But did you know that lookup tables (LUTs) also exist in MPC? Why explore MPC lookups? They help balance a common trade-off in MPC: secret sharing-based protocols have minimal total communication but require many rounds, while Yao-Garbled Circuits (GC) have a constant number of rounds but higher communication overhead. The most compelling application of LUTs is private ML inference (more on this in another post). However, there's an underexplored area: MPC LUTs for collaborative SNARKs. To support proof systems that leverage LUTs, we need to find efficient ways to compute zk LUTs in an MPC-fied manner. We are actively researching this area and would love to speak with anyone interested in this topic.
