📊 What is blockchain? A simple explanation for beginners 🔗
Hello, friends! 👋
Blockchain is the technology underlying cryptocurrencies like $BTC and $ETH. It is a chain of blocks, where each block contains information about transactions. Thanks to decentralization and cryptography, blockchain ensures the security and transparency of data.
Why is this important? 🌍
1) Transparency: all transactions are visible and immutable.
2) Security: data is protected from hacking.
3) Decentralization: there is no central control.
