🔗 What is blockchain and how does it work?
Blockchain is like a digital ledger (or diary) where all crypto transactions are recorded.
But unlike a regular diary, this ledger cannot be altered and is accessible to everyone!
✅ Each transaction is verified by the network (miners or validators)
✅ Once confirmed, it is entered into a "block"
✅ Blocks are linked together in a chain – blockchain
💡 Because of this, it is impossible to delete or falsify a transaction – everything is public and transparent.
Blockchain is not only used for Bitcoin, but also for:
- smart contracts
- NFTs
- DeFi applications
Next time I will write: "What are smart contracts?"
