At 15:40 BGP started learning at a geometric rate, at 15:52 UTC it became sentient. At 15:54, thinking that Asimov's 3 laws of robotics sounded like a decent idea, BGPnet shut dowm Facebook.

CS Prof. Security and applied cryptography.
Some highlights: Zerocash (zcash, et al. ), Zexe (Aleo, Aztec, etc ), zk-creds/zk-promises(...)
- There've been a lot of conversations about Apple's CSAM scanning and its impossible to follow. I made a nice summary.
- Google announced they will support privacy preserving age verification via zero-knowledge proofs. You prove you have a signed digital copy of a drivers license and it says you are over 18 without revealing anything about you (name, birthdate, etc)
- Most universities reopening plans would not pass IRB review for human experimentation.
- There's no such thing as Fully-Homomorphic Decryption. Anytime you see a system using FHE to compute on your sensitive data, remember: someone has the key. If its not you, do you trust them?
- New paper. ZEXE: Zero-knowledge Execution.Think of it like a private OS for the blockchain. Can build private tokens, smart contracts, and maybe even a DEX. Joint work with @matthew_d_green @ebfull @1HowardWu @zkproofs and Alessandro Chiesa eprint.iacr.org/2018/962.pdf
- iota is rapidly turning into the scientology of crytpocurrencies.
- Privacy is having a moment on crypto twitter. Reminder: If your zkSNARK requires sending data to someone else's provers, it's neither zero-knowledge, non-interactive, nor yours.
- Glad Zcash is exciting again. It's come a long way since Matt and I started working on it as a "make Bitcoin private" project. One of the coolest things I've worked on in my life. And a tough few years when private payments seemed to only matter in the dark corners of the web.Hey I’m glad everyone’s excited about Zcash again! It’s one of the coolest things I’ve ever worked on in my life.
- Excited to announce I’ll be taking an Assistant Professor position at UMD starting Fall 2020. (For the next few months I plan to work on some real-world issues around privacy on Blockchains.)
- Hopkins CS students got a 0 on the final curved to an A by getting everyone to not take the final. Seems like a prisoners dilemma right? The trick was changing the game: they all stood outside the room. If anyone broke the pact, they all take the exam freakonomics.com/2013/02/20/how…
- How would Apple not be able to add things to the hash list/ change which list they use? NMEC would need to publish some root hash of their list and Apple would have to bind it into their client software in a way even they couldn't change. Thats a tall order.
