Bitcoin 101: How Digital Money Works Without Banks | Kolkata
Details
# Every economy relies on a ledger to track balances, but Bitcoin is the first ledger maintained by mathematics instead of banks.
Most people hear about Bitcoin through news headlines about market prices and trading. But looking at Bitcoin only as an asset misses the point of how it works. Bitcoin is a breakthrough in computer science—a way for people around the world to agree on a shared financial record without relying on a central authority, bank, or government. This session breaks down the mechanics from scratch: how basic cryptography, simple math, and clever incentives build a completely open, finite digital currency.
## AGENDA
- What Is Money? : Understanding money as a shared ledger helps reveal why traditional systems require middlemen.
- The Magic of Cryptography & Hash Functions: Simple math functions create unique digital signatures that make records impossible to alter secretly.
- How a Bitcoin Transaction Works: Sending value across a peer-to-peer network requires proving ownership without exposing your private security key.
- Blocks & Proof of Work: Computers spend computing energy to lock transactions into immutable blocks, binding digital records to real-world energy.
- Game Theory & Decentralized Networks: Economic incentives ensure that keeping the system honest is far more rewarding than trying to cheat it.
- The 21 Million Supply Cap: Hardcoded code rules enforce absolute digital scarcity that no single person or institution can alter.
## WHO'S GUIDING
Led by Bitshala educators and open-source builders. Our sessions are led by active community members who build open-source tools, study the Bitcoin protocol, and advocate for transparent, open software.
## WHAT TO EXPECT
- Difficulty: Beginner level. Designed for absolute newcomers.
- Zero Fluff: No sales pitches, no trading talk, and no corporate slides. Just pure peer-to-peer technical literacy.
## IS THIS FOR YOU?
- You are curious about how money and technology intersect.
- You want to understand how Bitcoin works under the hood rather than follow market trends.
- You prefer clear, logical explanations over complex jargon.
- You enjoy asking foundational questions in a welcoming, hands-on environment.
Zero prior background in coding or finance required. An appetite for logic and clear thinking required.
Come discover how a few foundational ideas in math and computer science created a new way to move and store value around the world.
# About Bitshala
Bitshala is a Bitcoin-focused education initiative where we help developers, designers, and curious builders learn by doing. We run cohorts, clubs, workshops, a hackerspace, and community programs that make it easier for people to explore, contribute to, and build on Bitcoin. Our focus is on hands-on learning, proof-of-work, and growing alongside a community of people who care about open technology, design, and the future of money.
