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. 🟠

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

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. 🧡

🟠 Chennai Meet-up | 17th October | 4-6 PM

You press 'Send', your transaction is pending, & then it gets confirmed. But what happens in between?

- Who decides which block includes your transaction?
- Why do fees matter?
- And what happens when a transaction stays unconfirmed?

Join Bitshala for a hands-on session using mempool.space to watch Bitcoin transactions move through the network in real time.
