Blockchain is the technology behind all cryptocurrencies. But what exactly is it?
Imagine a large ledger, visible to everyone, that no one can modify alone. Each transaction is recorded in a "block", and these blocks are linked together to form a "chain". That's why it's called a blockchain.
What makes this technology revolutionary is decentralization. There is no bank, no government, no intermediary. Transactions are validated by thousands of computers around the world.
Before investing in a crypto project, always ask yourself this question: does this project really use blockchain in a useful way, or is it just marketing? A good project solves a real problem using this technology.
👉 Understanding blockchain is fundamental. Never skip this step.
