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.

Well said. Google and Facebook are classic Web2 examples, centralized platforms that control the login, data, and rules. Web3 shifts more control into the individual’s hands by using wallets for identity and blockchains for ownership and verification.
New to Blockchain — Looking for Guidance
Hi James 👋 I’m completely new to blockchain. My current background is AI automation. I’m really interested in learning more about blockchain/Web3 but not sure where to start in the right way. Could you please share: - A good learning path for beginners - Any recommended resources, courses, or core concepts to focus on first

Hey Bao 👋 Welcome in! I recommend starting with fundamentals and security. Most people rush into crypto without understanding the basics, then get burned by scams or simple mistakes. This space can be a minefield, so discipline matters. Learn what crypto is, how transactions work, and how a wallet works. Then move straight into security habits so you know how to protect yourself. A simple but effective plan is to watch a few tutorials on YouTube and follow along with our BUNI lessons as we roll out more curriculum. While you do these things, explore platforms like CoinMarketCap (token tracker) and CoinDesk (news platform) to get familiar with the landscape. As your confidence grows, you’ll naturally discover more resources and a clearer next step forward.
🧵 Discussion Thread: Protecting Your Seed Phrase
🔑 Seed phrases are the master key to your wallet. They’re your 12–24 word recovery phrase. If someone gets it, they can take everything, and there’s no password reset or support desk in crypto! 🚫 Protecting it is less about being “paranoid” and more about building a simple system that’s safe and easy to follow. ✅ What’s your seed phrase setup strategy? Share what you do to stay safe (and what you avoid). Paper vs metal, and whether you keep one backup or multiple backups. 👇

That’s a strong setup, Lisa. Two offline metal backups in separate places hits the sweet spot of durability and redundancy, and avoiding any digital copies removes a huge chunk of risk. I always tell people not to store their phrase digitally since screens get seen and data can get accessed more easily than people think.
Welcome to Blockchain University
Hello everyone, I’m James Odom, and I’m excited to officially kick off Blockchain University. Our first course is now live: BHS 101 – The Birth of Bitcoin. This is a primary-source based course focused on Bitcoin’s origin story as a historical and technical event. We cover the problem Bitcoin was solving, early digital cash experiments, Satoshi’s design priorities, the whitepaper’s key decisions, the genesis block, early mining, and what Bitcoin’s early years teach us about security, decentralization, and scalability. If you’re new here, start at the Introduction and work your way down the lesson list at your own pace. If you’re experienced, you’ll still get value from revisiting the original context and seeing how the early design tradeoffs shaped everything that came after. Quick intro questions: Comment below with (1) your background level (new, intermediate, advanced) and (2) what you want to learn most in crypto right now. Glad you’re here. Let’s build more amazing content moving forward!
