We like the @kevaundray
Kev Wedderburn is the father, architect, and team lead behind @NoirLang, a universal ZK circuit writing language funded by Aztec Labs.
We’re excited to bring you a profile of the enigma behind the DSL transforming ZK programming:

Is someone monitoring the @CryptoHack__ github? I submitted a PR to the ctf_archive some time ago, but there is no activity

If you want to learn about Aztec's upcoming architecture, a wonderful talk by Aztec Lab's @mike_connor has just been published. Mike's got the gift of the gab, so I'd highly recommend watching how we are trying to build a "zk-zk-Rollup"
Is there someone from @DelendumV I can contact directly? It seems their benchmark project is not being monitored by the team

I had a blast at the ZKSummit9 last week. I wanted to thank @AnnaRRose @kobigurk and everyone else who made it happen. This was my first ZKSummit and I loved it.
I was extremely lucky to give a talk, too. If you are interested in various ways of improving circuit security, here is my talk on the fuzzing approach.

It seems even without ÆPIC SGX as a single security mechanism is just not enough
New speedrunning category unlocked: "snip20% glitchless."
We found and demonstrated more privacy hazards in TEE-based blockchains, especially Secret Network, this time without breaking the TEE itself

@youtubemusic is a unique music app. The only one that managed to lose the voice frequencies in a song (same on several devices). The vocals are just gone. I'm wondering what sort of bug could lead to this.

I wrote a cryptographic task for @CTFZone based on an error in assembly implementation in Barretenberg found by @GuidoVranken . Unfortunately, nobody managed to solve it in 48 hours. Here is the write-up:
This was a very nice challenge. Thanks to @__geometry__ for organising it. Finally looked at Groth16.

@Hacker0x01 Is there any way for bug bounty hunters to contact you, since you ignore [email protected]?
