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 🎟️ luma.com/bitshalaboss 🟠 Bitmela | 30–31 October | Jaipur 🎟️ thebitmela.com/#tickets To everyone who joined us in Vadodara, thank you for making these conversations possible and to everyone still deciding, we'd love to see you in Jaipur next week!

Our co-founder took three years to find his way into Bitcoin full-time. At Bitshala, we’re working to make that path clearer for the next generation of Indian developers. No shortcuts, just a better-supported path to building a career in Bitcoin. Watch @RajarshiMaitra's session from @BTCPrague below 👇

An incredible evening of hands-on learning in Chennai! 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 Programming Bitcoin Season 2 graduates! 🟠 8 weeks of learning by doing. From setting up a local regtest environment to exploring cryptography, transactions, scripting, and networking, our cohort went deeper into the code that powers Bitcoin. The goal was simple: move beyond theory and start working with Bitcoin hands-on. Congratulations again to everyone who put in the work and earned their certificates. 👏

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. 🟠

Every Taproot signature comes down to one equation: s = k + e·x So why can't anyone forge it? 🔐 Tonight we finish our signatures deep dive with @sha512rma: → ECDSA vs. Schnorr → Multisig + a critical attack vector → The Forking Lemma: forging Schnorr = solving the DLP 8 PM on Bitshala Discord: discord.com/invite/STeQFVEWf…

That’s a wrap on Building Bitcoin in Rust (BR) Season 1! 🎓🦀 Over 10 weeks, our builders worked through the Braiins curriculum, progressing from Rust fundamentals like ownership and traits to async networking and Bitcoin node design. The goal was to move beyond learning Rust and start applying it to Bitcoin development. Watching participants turn that learning into production-style projects has been a highlight of this cohort. Congratulations to everyone who put in the work and earned their Proof-of-Work certificates. ⚡️ The next step in Bitcoin development starts with builders like these. 🟠
