I’m excited to share that our paper, “Tokenized Peer Review: An Adaptive Blockchain Mechanism for Open Source Supply Chains,” has just been published in the Journal of Network and Systems Management (Springer)! 🎉

DO NOT use Telegram in sensitive applications. Telegram does not need to have its message encryption broken for users to be tracked at the network layer. Telegram sends MTProto over unencrypted TCP, exposing auth_key_id - a long-lived identifier tied to the client’s authorisation key. An ISP, hotel WiFi operator, mobile carrier, transit provider, or surveillance system on the network path can see that identifier if they can observe the traffic. It can remain stable across app restarts, IP changes, VPN use, network switches, and location changes. Secret Chats protect message content, but this leak is below that layer. That makes the attack passive. The risk is in retroactive correlation. Think a journalist using Telegram from different networks for months, then joining hotel or corporate WiFi under a real name. That one identity anchor could make old logs searchable for the same auth_key_id. The fix is simple - mandatory transport encryption for all MTProto connections, with no unencrypted fallback. Telegram chose not to do this. Source: @kaepora https://t.co/TJALYAwaOs

Google used a ZK proof to disclose a quantum breakthrough that cuts the cost of breaking cryptocurrency by 20x without handing attackers the circuit. We found anyone could forge a “proof” of an even stronger attack. 🧵

No site da piauí, o jornalista Marcelo Soares escreve ao estudante que recebeu nota zero na redação da Fuvest - com um texto marcado pelo tom rebuscado e que motivou ação contra USP.

Over 2 years ago, I did this video with Yaniv Hoffman explaining how Russia is spreading hate and dissension on the Internet. People laughed.

Yesterday, X (Twiiter) began showing the location of many of these accounts.

As expected, these MAGA, America First accounts are based in Russia, Pakistan, India and Africa.

More than a machine, it’s a living artwork born from craftsmanship, creativity, and pure passion.

if you’re an EE, CS, or cryptography student

write your thesis on public key cryptography at the image sensor level

Proof of Physical capture will become a backbone of society soon.
