Introduction
Everyone talks about blockchain, but what does it mean? Simply put, blockchain is the technology behind cryptocurrencies — but it’s also much more. Let’s break it down.
1. Blockchain = Digital Ledger
It’s like a notebook that records every transaction. But instead of one person holding it, millions share the same copy.
2. Transparency and Trust
Once information is added, it cannot be changed. That makes blockchain secure and trustworthy.
3. Use Cases Beyond Crypto
- Finance: Bitcoin, Ethereum.
- Healthcare: Patient records.
- Supply chains: Tracking goods.
- Voting: Transparent elections.
4. Example
Imagine 100 people write in the same notebook. If 1 cheats, the other 99 copies prove the truth.
5. Blockchain in 2025
Companies, banks, and even governments are using it. It’s no longer just about Bitcoin.
Conclusion
Blockchain is the foundation of crypto — and a revolution in how we store and share data.
