At our Vadodara meetup, we went deep into Bitcoin’s 21 million supply limit, Proof of Work, difficulty adjustment, and how full nodes independently enforce the rules. We also talked about what’s coming up in Jaipur: BOSS Summit Winter 2026 and @thebitmela. A few folks even grabbed their last-minute tickets right there! If you've been thinking about joining us, consider this your last reminder. 🛠️ BOSS Summit | 27–29 October 🎟️

Want to learn Rust? Learn it by building something real. Building Bitcoin in Rust (BR) Season 2 is now open for registration: an 11-week, hands-on cohort based on Braiins' Building Bitcoin in Rust by Lukáš Hozda. Instead of isolated exercises, you'll learn Rust in the context of a real system, Bitcoin. That covers ownership, traits and testing, then mining, async networking, node design and wallet construction. What you'll take away: • Rust fundamentals with real context • Domain modeling for Bitcoin • Production-style engineering habits • Concurrency and async skills • An end-to-end Bitcoin builder path Who it's for: developers who know at least one programming language and want to learn Rust through practical building. 🗓️ Starts 10 Nov 2026 · Tuesdays, 8:00 PM IST (2:30 PM UTC) 🎓 Proof-of-Work certificate on completion 📌 Apply now:

Just a day after ClaudeAI brought attention to the origins of NIST’s elliptic curve parameters, we gathered in Pune to explore the mathematics that helps secure Bitcoin. We spent time understanding secp256k1, ECDSA, and Schnorr signatures. We also looked ahead at quantum computing and what it could mean for Bitcoin’s cryptographic future. These conversations matter because security is never something we should accept blindly. We should understand how it works, question its assumptions, and stay curious about what comes next. That’s what we want Bitshala to be about. People coming together to learn, ask difficult questions, and understand Bitcoin a little more deeply than they did before. Thank you to everyone who joined us in Deccan, Pune on 17-Oct-2026, and made the session what it was. The best part of learning is that there’s always more to discover. 🟠

Today (17-Oct-2026) in Chandigarh, just one person showed up for our Bitcoin meetup. We sat down, had a conversation, and started with a simple question: What is money? We went deep into how to build a solid foundation, exchanged some read's like The Internet of Money and Broken Money to understand further. Every conversation counts when it comes to orange-pilling the world 📚🚀

An incredible evening of hands-on learning in Chennai (17-Oct-2026). We took a deep dive into the inner workings of Bitcoin with a session at Bitcoin: Watch It Work. From the moment you hit 'send' to final confirmation, we explored it all: 🔹Transaction structures & the Mempool 🔹Understanding fee rates 🔹Hands-on RBF & CPFP on Testnet using @SparrowWallet 🔹Leveraging @mempool features to visualize the network Huge thanks to everyone who joined us to watch Bitcoin work in real time ⚡️

Congratulations to our Mastering Bitcoin Season 6 graduates! Over the last 10 weeks, they worked through the 3rd edition of Mastering Bitcoin by Andreas Antonopoulos, building a deeper understanding of the technology that powers Bitcoin. From transactions and HD wallets to mining and consensus, they went beyond the surface to understand how Bitcoin actually works. Every chapter completed. Every concept questioned. Every bit of effort earned. Congratulations to everyone who earned their certificates. The real journey begins when you take what you've learned and put it to work. The rabbit hole goes deeper. Keep going. 🟠

That's a wrap on Building Bitcoin in Rust (BR) Season 1 🎓🦀 Over the last 10 weeks, our cohort dived deep into the Braiins curriculum. They worked through Rust's foundations, ownership and traits, all the way to async networking and Bitcoin node design. What stood out most was the transformation. Participants arrived Rust curious and left shipping production-style Bitcoin projects. Everyone who completed the work has earned a Proof-of-Work certificate. Special recognition goes to our top participants: 🥇 ibearua 🥈 Wandia Mugo 🥉 Anshuman 🎁 yunus_abdul 🎁 colmwanga And honorary mentions for R27, aditaya, NisargXplores, oneshheraldofnothing and sreepadam. Bitcoin's future depends on engineers who understand it from the ground up. Programs like this are how we build that bench, and this cohort shows the next generation of Bitcoin engineers is already here. 🚀 Thank you to every participant, mentor and contributor who made Season 1 happen. 🧡
