And I continue my marathon of learning cryptocurrency and today is Day 2, thank you for your support! 📚 Day 2: What Is Blockchain? Simple words for a complex topic 1. 📦 What is blockchain? Blockchain is like a chain of blocks that store information about transactions (crypto transfers). Each block contains: 📄 a list of transactions, ⏰ a timestamp, 🔒 a cryptographic code (called a hash), 🧱 the hash of the previous block (this links the blocks into a “chain”). To make it simple: 👉 Imagine a cash register that records every purchase in a notebook — but this notebook is public and cannot be altered. 2. 🔒 Why is blockchain considered secure? 📁 Data cannot be changed — once something is recorded, it cannot be deleted or edited. 👥 Decentralization — copies of the chain are stored on thousands of devices, not just one server. 👀 Transparency — anyone can view the records. 3. How does it work? — A simple example: ⬇️

📚 Day 1: What Is Cryptocurrency? (simple explanation) 1. The Main Idea: Cryptocurrency is digital money that exists only online. It works without banks or governments. You control your money yourself. Key features: 🔗 Decentralization — no central authority or control. 🔒 Security — data is encrypted and protected. 🌍 Global use — you can send money anywhere in the world. 🕓 Speed — transfers happen within minutes or even seconds. 📉📈 Volatility — the price of cryptocurrencies can change a lot every day. 2. How It Works: Imagine a giant notebook (this is called blockchain) where all transactions are recorded — who sent money to whom and how much. This notebook: is visible to everyone in the network, is almost impossible to fake, is constantly updated automatically. 3. Example: You have 1 Bitcoin. You send it to me. This transaction is recorded in the blockchain. Everyone can see: you sent it, I received it. No banks, no middlemen, no paperwork! 4. Why Is It Cool? ⬇️
