The Private Cloud Compute Security Guide is out - check it out, the security engineering that went into this effort is really impressive (and I'm not saying that just because I worked on it, I promise)!

Super excited to share how Apple is deploying homomorphic encryption! It'll be used for private information retrieval (mail, calls, content restrictions) and private nearest neighbor search (photos). This was an amazing effort across multiple teams! 💪🎉 machinelearning.apple.com/re…
Working on security and cryptography at Google, I see a lot of interesting reviews! A recent review I did looked at RSA blind signatures (which are used in the VPN by Google One) and their role in preserving user privacy:

It's been awesome working on ZkVM with the protocol team at Interstellar. Read more about the project, and its future with Stellar, here! bit.ly/2VVlVgM
If you want to understand how Bulletproofs works, or want to learn about what I've been working on with @oleganza and @hdevalence, you're in luck! I wrote a medium post explaining Bulletproofs, Cloak, and (briefly) ZkVM:
