Yesterday I had to sign a PDF and I was very surprised to see... This new feature that opens the camera to scan your real signature and digitalize it. First time i've used it.

We are testing some cool ideas with @Zcash (without TEEs). One of them is using FROST multisig and "vaults" together with Noir from @aztecnetwork for generating proofs instead of Halo2. Let’s see how it goes.

I was working with @PhalaNetwork and noticed that when you deploy using the same tag name, Docker does not update the image internally, so the new image is not loaded. This seems to be a bug. Also, in the new UI it is a bit confusing to understand the difference between TDX attestation and Docker attestation.

1/ 🧵 If you’re building in ZK, your code is only as strong as your math. I’m sharing a gem from Carnegie Mellon University (CMU): "Everything You Always Wanted To Know About Mathematics." A must-read for systems engineers. 🦀✨

pablito.eth 🦇🔊 @ EthCC 🇫🇷
We are seeing a new BIG wave of Telegram accounts takeovers (thousands hacked daily). We are highly suspicious but can not prove it yet, that this is happening because SMS with auth codes sent by Twilio are being intercepted by multiple threat actors at the Tiers level (as we discovered in march 2025). - In the meanwhile, the way to protect from this is very simple: Settings > Privacy and Security > Two-Step verification: turn it on, write it down and configure a secure email. - If your Telegram account is hacked, you are NOT gonna get it back and also all your contacts and conversations are gone forever (unless you are a high-profile). Stay safe

@waleswoosh You don't get it son.. ZK is the innovation frontier, beyond crypto, and aztec team is one of the most strong/serious teams out there.

Genuine question: Who are the buyers on Upbit? And are they stupid? Why would anyone buy vaporware coins after a 3x pump, knowing it'll likely nuke back to its pre-listing price within 24 hours?

Sigan con la cultura vibecoding, deploy con Claude, acceso a todo, 7 agentes en paralelo, deployo todo automático mientras juego al lol, así vamos a terminar. Todo el software con vulnerabilidades y sin saber absolutamente nada. Y saben que es lo peor? Que esto está pasando en sus empresas, todos los incentivos están puestos para que los devs dejen a Claude corriendo generando código y salga directo a producción. No es la primera ni última vez que vamos a ver esto.

🚨Claude Opus 4.6 wrote vulnerable code, leading to a smart contract exploit with $1.78M loss cbETH asset's price was set to $1.12 instead of ~$2,200. The PRs of the project show commits were co-authored by Claude - Is this the first hack of vibe-coded Solidity code?

@mert It is very difficult to make changes and get them approved in the Bitcoin protocol. This is both its principal benefit and its existential threat a black swan event or Q-Day could happen overnight and revert "the industry" 10 years in the past probably, Ethereum is working on it

these people are idiots a decentralized system is uniquely vulnerable to such attacks precisely because it's decentralized you can ask a bank to reverse a fraudulent txn because the bank has ultimate authority you can not ask bitcoin for a refund
