Honored and humbled to be giving the second invited talk at ASIACRYPT 2023 tomorrow. Hope it will be somewhat interesting! asiacrypt.iacr.org/2023/program.p…


Fake accounts galore @pwuille Was followed and DM'd from the second one on the list (presumably cryptocurrency related scams again)

"Oh?" - me noticing a post about NIST PQC and Kyber on the HackerNews front page; "Oh no" - after reading the domain name; [Facepalm] - after taking a peek at the comment section.


Non qu'on ait jamais eu d'illusion à ce sujet, mais il faut arrêter de donner des responsabilités à des startupeurs, vraiment.

La France doit être souveraine sur les nouvelles technologies basées sur la blockchain, comme les NFT. Car en soutenant l’innovation, nous créerons de l’emploi.



I didn't have high expectations but I'm still disappointed. Does anyone know real people remaining at @X that could address this straightforward case of impersonation?

Indeed, I'm blocked so it wasn't showing up in search results! Reported; let's hope @X acts swiftly...

That's concerning. Can't find the account right now so I assume it's been closed down, but if anyone received a message like that, don't hesitate to report it. As a reminder, the only blockchain I endorse is: store.newae.com/blockchain/

Hey @mtibouchi, you have a fake crypto scam account with an 0 instead of the o in your login... (Or you decided to speak to me in English about crypto trades...)



Squirrels!

I don't like seeing that we picked the darkest timeline... So this thread, is going to be a timeline cleanse of AI generated squirrel on vacation pictures...
