I Want to Hear From You 👇
I’ve had to step away for a short stretch because I’ve been locked in building a crypto protocol, while staying active with my investing and trading ventures. It has been a focused season of building and execution, but I have not walked away from Blockchain University. At the same time, I want to be honest with you. I’m narrowing my focus, and I’m evaluating what deserves the most energy moving forward. I believe Blockchain University has real potential, but I want to know if you feel that too, and if this is something we should keep pushing until it becomes a serious destination for learning. So tell me, are we going somewhere with Blockchain University? Are you looking forward to more course content, and what do you want to learn next? Drop a quick comment with your thoughts so I know you’re real and engaged, and so we can shape the plan moving forward as a community.

🧵 Discussion Thread: Graphics Style Feedback
Quick question for everyone! 👇 What do you think about the current Blockchain University graphics approach (monochrome, clean icons, simple diagrams)? 🎨📚 I’m building these in Photoshop by hand, and I like that they’re simple, consistent, and fast to produce. I want to avoid the flashy stock graphic look and the overly common AI-generated style that’s everywhere right now. My goal is clarity and consistency while we build the foundation. That said, I’m totally open to evolving the style or even doing a full design overhaul later when we gain more traction and get stronger feedback from the community. 🔁✅ I’ll also be adding screen recordings and on-camera video as the curriculum matures, and I’ll likely circle back to published lessons to layer in extra elements as we refine the direction. For now, I’m focused on making the written lessons and visuals as clear as possible. 🎥🖥️ What’s working for you, and what would you suggest? I’m genuinely open to feedback and constructive criticism. Be honest and speak your mind, we’re all students of each other here. 🙏

Today's story for every Secure Vibe Coding student Nation-state hackers are now using fake Claude software to install malware. Here is exactly what to watch for. A China-linked espionage group called JadeProx was caught this week running a spear-phishing campaign that impersonated Anthropic Claude software to deliver malware. The targets were technical professionals — government IT staff, developers, researchers. The exact population that uses Claude Code daily. This is not theoretical. It happened. A zip file arrives named something plausible — "Claude_Dev_Update.zip," "ClaudeCode_v4.zip," "AnthropicTool_Setup.exe." It looks like a software update. A developer who uses Claude Code regularly is the target. They download it. They run it. They have installed TriBack Loader, a persistent malware implant that gives the attacker ongoing access to their machine. Your Masterclass community needs to know one thing: legitimate Claude software comes from exactly four places — claude.ai in a browser, the Claude desktop app downloaded from anthropic.com, Claude Code installed via npm install @anthropic-ai/claude-code, and the Claude mobile app from the official app stores. Anywhere else is potentially JadeProx. Share this with your community this week. It is the most direct, actionable security intervention available given today's news. The Hacker News — JadeProx · Group-IB full report 2. Breach Post-Mortem — Course Content Module JadeProx: How an OPSEC Mistake Exposed a Global Espionage Campaign What happened JadeProx is a China-nexus espionage operation that simultaneously targeted a Vietnamese hospital's medical imaging system, Malaysia's Ministry of Foreign Affairs, universities in Hong Kong, and government entities in Honduras and Venezuela. It was exposed not by a sophisticated intelligence operation — but because one operator left a staging server open to the internet with everything visible: bash history, victim paths, phishing packages, post-exploitation tools.

Web3
Talking of Web3 This is the information I have gathered about it and still in the process of learning about this new tech. Web3 is a decentralized internet built on blockchain technology, where users theoretically have more control over their data, identity, and digital assets without relying on centralized platforms like Google or Facebook.
