Understanding Web3 terms is a big advantage when looking for a job in this field. That’s why we’re starting a new series where we explain complex topics in simple terms! Let’s begin with blockchain: what it is and how it works.

Blockchain is a way to store information securely and transparently. Think of it as a digital notebook shared across many computers. Here's how it works:

1️⃣ Data is stored in "blocks," and each block is linked to the previous one, forming a chain. Once data is added, it can’t be changed, making the system reliable and secure.
2️⃣ Unlike traditional systems that rely on one central authority (like a bank), blockchain is decentralized. This means no single person or company controls it — instead, many computers work together to verify and store data.

🔑 Key features
Security: Data is protected by cryptography and can’t be tampered with.
Transparency: Everyone can see the transaction history.
Decentralization: No single point of failure or control.
Blockchain powers cryptocurrencies like Bitcoin, but it’s also used in supply chains, healthcare, finance, and even voting systems.
