We took full advantage of the situation to explore the first principles of money: from the properties of gold to the evolution of fiat and the emergence of Bitcoin.

Sometimes the best conversations happen when you throw the script away! ⚡️

🟠 Bitshala Meetup in Surat | Decoding Bitcoin

Our first meetup in Surat was a meaningful conversation around one question:

What problem was Bitcoin created to solve?

To understand any solution, one must first understand the problem it was created to solve.

We explored the history of money and the monetary problems Bitcoin emerged in response to, helping participants understand why Bitcoin is fundamentally different from just another asset.

A few wanted to go deeper, so we happily recommended The Bitcoin Standard by @saifedean and Broken Money by @LynAldenContact as starting points.

Thank you, Surat. We’re just getting started. 🟠

Huge thanks to everyone who joined the Hyderabad Meetup today 🧡

We went deep into Bitcoin wallets, self-custody, and what it really means to hold your own keys.

Your Bitcoin wallet doesn’t hold your bitcoin. It holds the keys that control it.

So what does it actually mean to own your Bitcoin?

- How do wallets work?
- How should you back up your recovery phrase?
- How do you verify transactions without relying on a third party?

Join Bitshala to learn the fundamentals of Bitcoin wallets and self-custody.

Just wrapped an incredible Bitcoin multisig workshop in Chennai 🟠🧡

What we covered hands-on:
🧠 Multisig basics - why 1-key security is a single point of failure
🔑 Generated 3 independent seeds using @SeedSigner
📤 Loaded XPUBs & built a 2-of-3 multisig wallet on @SparrowWallet + @nunchuk_io
✍️ Created a 2-of-3 transaction on both wallets
🔄 Exchanged PSBTs between signers
✅ Broadcast the final signed transaction

From seeds to a live broadcast in one session, that's how you truly understand multisig. 🔐

Huge thanks to everyone who showed up, built, and learned together. 🟠
