ANNOUNCEMENT: LAUNCH OF A NEW BITSHALA CLUB 🚀⚡️ The Cryptographic Foundations of Bitcoin Join us for our new club every Thursday at 8:00 PM IST / 2:30 PM UTC beginning from 06th Aug. In this club, we will learn what Bitcoin is actually made of. 🗓️ When: Every Thursday 🕕8:00 PM IST / 2:30 PM UTC 🎙️Hosted by: @sha512rma, M.Sc. Cybersecurity, Focus areas: ZK-ML, verifiable inference and compute, decentralized AI, applied cryptography, LLM guardrails, red-teaming, and differential privacy. We start with one-way functions and what "hard" really means in cryptography. From there we work through hash functions and how they become Proof-of-Work, Merkle trees and the proofs that let light clients verify a block, elliptic curves and the secp256k1 group your keys live in, ECDSA and Schnorr signatures, and finally threshold schemes like MuSig2 and FROST. Bitcoin's security is not a matter of trust or opinion. It rests on a handful of mathematical assumptions, and in this club we will implement them ourselves.

Bitcoin Wallets: You Don't Store Bitcoin, You Manage Keys | Pune 📅 Saturday, 08th August ⏰ 4:45 PM - 7:00 PM Your wallet holds zero Bitcoin; it holds the exact mathematical secrets required to convince a global network that you have the right to move it. In this Bitshala meetup, we abandon consumer abstractions to focus on protocol reality: wallets are deterministic cryptographic key managers that construct and sign state transitions for an open ledger. 📌 Register now: https://luma.com/12arih4f

Join us today (31-Jul-2026) at 8:00 PM IST / 2:30 PM UTC for Bitshala Reading Club We’re in Week 3 of "The Psychology of Money" by Morgan Housel in the Bitcoin Reading Club. Today’s Reading Club explores four ideas from The Psychology of Money about building lasting wealth through disciplined saving, wise decisions, patience, and resilience. Join us for practical lessons on money, wealth, and long-term success. Join us in lounge of Bitshala discord server for the session : https://discord.com/invite/STeQFVEWf9

Bitcoin Transactions, Blocks and Mining | Andheri, Mumbai 📅 Saturday, 08th August 🕛 11:00 AM - 2:00 PM Bitcoin has no accounts, no balances, and no central server, yet it reliably tracks value across thousands of independent nodes. In this session, we trace the full lifecycle of a transaction, from elliptic curves and address derivation to mempool dynamics, Merkle trees, and Nakamoto consensus, culminating in constructing and broadcasting a raw transaction directly onto the Bitcoin testnet. 📌Register now: https://luma.com/qi8cqorq

Our first Bitcoin meetup in Kolkata is here! 🎉 Bitcoin 101: How Digital Money Works Without Banks 📅 Saturday, 22 August 🕦 11:30 AM–1:30 PM Every economy depends on a ledger to keep track of who owns what. Bitcoin is the first global financial ledger maintained by mathematics, cryptography, and a distributed network—not by banks. Join us for an interactive, beginner-friendly introduction to Bitcoin and how it works. No prior knowledge is required—just bring your curiosity! 📌Register now: https://luma.com/ch87n8jh

Join us today (28-Jul-2026) at 8:00 PM IST / 2:30 PM UTC for Bitcoin Mining Club Today’s topics: i) Guest Journey: From non-tech to Bitcoin miner with Rajendra.sats ii) Live Demos: Node setup, port forwarding, templates, and pool mining iii) OCEAN Pool: Buying hash power and routing it directly to the pool Join us in Bitshala discord lounge: https://discord.com/invite/STeQFVEWf9

🚀 Learn Bitcoin from Command Line (LBTCL) Season 4 starts has officially begun at Bitshala. Learn Bitcoin from the command line through a hands-on, 6-week cohort covering Bitcoin Core, node management, scripting, and real-world workflows.
