We’re super excited to announce our $4.65m seed round led by @polychaincap, open source our fully homomorphic encryption (aka FHE) compiler, and kick off our grants program!. Continue reading for all the juicy details 👇.

If @zama_fhe and @randhindi believe in their work, we invite them to compete with @sunscreentech in a way that moves the industry forward rather than engage in secret campaigns of intimidation, IP trolling, and speech suppression. Thread 🧵👇. On December 3, following a 6+ month.

Today, we’re excited to launch the 1st version of our ZKP compiler—aimed primarily at engineers trying to work with both FHE and ZKPs. How do FHE and ZKPs fit together? And why did we build a brand new ZKP compiler?. Read our two part series to find out!.

Can threshold FHE be used to *improve* the MEV extraction process? More broadly, can FHE help make auctions both private + verifiable?. Excited to showcase our demo of an FHE-enabled auction with the Sepolia testnet! Get your ETH ready 😉.

So what’s next for us? We’ll be building out a complementary zero-knowledge proof library for our FHE compiler and working on integrations with storage solutions. If that sounds exciting to you, come join us at ! 🧑🤝🧑.

Our newest demo and blog post are here! Building a truly *dark* dark pool (courtesy of FHE). There’s a little something for everyone — threshold cryptography, NBBO, toxic order flow, and more ✨.

We’ve been working on an FHE compiler that makes FHE easy for developers to use without compromising on performance. There are some FHE compilers out there but these are all by researchers, for researchers. We’re proud to say that our compiler is one of the fastest🏃.

FHE has the potential to bring privacy to new applications and new users. Sadly, the technology has long been out of reach for developers!. Initially, the issue was efficiency. For the past few years, the main challenge is usability! FHE is too hard for non-experts to use🧐.

Is an FHE Layer 2 on @ethereum feasible? Kicking off a thread on ETH research to start exploring:

@ObadiaAlex Project idea started at @NuCypher where Ravital was looking into private smart contracts (thinking about security models, what privacy meant in this context, and functionality). Project was prev called SPF as an abbreviation (obv a terrible name) and evolved into Sunscreen.

@Maddiaa0 @Janmajaya_mall Super cool! We've been experimenting with auctions as well and various privacy assumptions. Would love to see how this would work with threshold FHE + ZKPs added.

@0xMaddington @andreisambra @miguel_de_vega I believe @PrivacyScaling have also been exploring this but using halo2. we just ran one quick experiment on our macbook to see how halo2 compared to what we were using for the bfv (fhe) scheme--iirc verification was ~4x faster but proving was ~2x slower.
