@0xPolygon @bobbinth Congrats @bobbinth + I like the name, FYI Miden is the word for Zero in Greek, thus I guess from Zero (Miden) Knowledge Proofs!

Did you know that in @SuiNetwork one can verify the encryption of the same message under two different public keys? We literally implemented this @StackOverflow answer: Some exciting applications: a) Encrypt transaction details for both the recipient

ZKProof workshop '22 accepted talks. Our @huitseeker will show how we optimized Groth16 verification over BLS12-381 by marrying Arkworks + BLST + required conversions in our fastcrypto Rust repo. Yes @SuiNetwork will natively support a zkp api! #blockchain #cryptography #ZKSnarks

Blockchain research has advanced systems and cryptography, probably like nothing else in our history. Great constructions and record performance in ZKP, sig aggregation + threshold, MPC, BFT, DKG, VRF, VDF etc and most importantly: robust implementations for all of the above.

Surprise! Denver, Feb 26, 4pm. Cool Q&A session around Sui ZKP innovation, why Groth16 isn’t dead, how we broke most of today’s solvency proof schemes, and why you’ll see new models for obfuscated NFTs in Sui like nowhere else 🙏 @AntalphaGroup ✍️ here:

Did you know that in Corfu Greece there is a Cryptographer’s shack? Soon it will be a library with printed papers from many notable authors. It’s super small but next to the historical fortress. #cryptography Ask for a key if you are a cryptographer & you ever visit the island.

👀 a 🍏 honestly! Project FOCCFE, signed by @b1ackd0g Sui research is working on at least a dozen of new jaw-dropping protocols! I 💯 envision this chain to be the next 🍏 in web3! Back to back 2am chats w @EmanAbio cause we couldn't believe some things were even possible.

If you are attending @SuiNetwork Paris Basecamp, write a short prediction (of any kind) in a piece of paper, fold it, and I’ll make sure we put it in our first Sui time capsule. We’ll reveal it (video covered by press) in exactly 2years, April 11th, 2026.

This year I'll hide 10 stainless steel waterproof time capsules across the world. All of them will have a local newspaper & an engraved @SuiNetwork private key with at least $1000 assets at the time of sealing. I'll randomly provide treasure hunt hints when I start. Good Luck!
