Bitcoin 101: How Digital Money Works Without Banks, Kolkata edition (22-Aug-2026)🚀🚀 15 curious minds including newcomers, finance professionals, and software engineers, came together to understand Bitcoin. The session was purely Bitcoin-focused, with participants asking thoughtful questions and showing genuine interest beyond their professional backgrounds. We also introduced them to the Bitshala community, clubs, cohorts, BOSS Summit, meetups, and ways to contribute to Bitcoin open source. Follow us to get update on next meetup 🙌🚀

Had an engaging Bitcoin 101 meetup in Vashi, Navi Mumbai (22-Aug-2026)⚡️ We covered Bitcoin’s technical foundations, from transactions, keys, UTXOs, and nodes to mining, consensus, halving, and the 21M supply cap. We also introduced participants to the Bitshala community, clubs, cohorts, BOSS Summit, meetups, and pathways to contribute to Bitcoin open source. We host meetups across cities.

Five cities. Five gatherings. One idea worth understanding deeply. This weekend, Bitshala meetups take place across Mumbai, Delhi, Pune, Kolkata, and Chandigarh. Different people. Different questions. Different paths into Bitcoin. But the principle remains the same: Learn how it works. Understand why it matters. Then build. 22–23 August - https://luma.com/bitshala✨ See you there🚀

Mastering Bitcoin (MB) Cohort - Season 6 Week 1 is TODAY! 🚀 Registration for Mastering Bitcoin Cohort Season 6 is still open, but today is the last day to join.

Join us today (20-Aug-2026) at 8:00 PM IST / 2:30 PM UTC for the next session of The Cryptographic Foundations of Bitcoin ⚡️ This week, we’ll continue our journey into one-way functions (OWFs)—the fundamental building blocks behind Bitcoin’s security. We’ll move from theory to the mathematics that protects your keys: i) The Factoring Assumption: Why multiplying large primes is easy, while reversing the process is hard—and how this idea supports cryptographic security. ii) Proving Security: An introduction to reduction proofs and how cryptographers demonstrate that breaking one problem would require solving another supposedly hard problem. iii) Bitcoin's Math (DLP & ECC): Explore the Discrete Logarithm Problem, generators, and how these concepts map directly to Bitcoin’s secp256k1 elliptic curve. iv) Building Digital Signatures: See how a one-way function can be used to construct a digital signature scheme, including the Lamport one-time signature.

Join us today (19-Aug-2026) at 8:00 PM IST / 2:30 PM UTC for TradFi & Bitcoin Club This week, we’ll explore Firefish—a Bitcoin-backed lending marketplace that helps BTC holders access liquidity without selling their bitcoin. Firefish connects borrowers with investors, using Bitcoin collateral escrow rather than traditional custodial lending. Investors can fund these loans and earn interest, while borrowers retain exposure to their BTC. We’ll be joined by Finn from Firefish for an introduction, discussion, and live Q&A.

Why is BTC Known as Internet Money? | Hadapsar, Pune 🗓 Saturday, 22nd August 🕙 5:00 PM - 7:00 PM Bitcoin isn’t money because of its cryptography; it’s money because it survives an environment where every participant is assumed hostile. To understand why Bitcoin functions as native internet money, you have to look past the surface-level protocol and examine the adversarial engineering that makes its state machine virtually impossible to alter or shut down. 🎟️Register now:

Thanks to everyone who joined and made the conversation so engaging! 🙌

Student to Contributer : How to break into the FOSS world | Parul University, Vadodara (14-Aug-2026) We built a broken game on purpose and challenged students to: → Find the bug → Write the fix → Open a PR → Ship it The fastest fixes won Bitshala swag & that’s how we spent the day at Parul University Bitshala Open Source workshop.
