The blockchain is one of the most revolutionary technologies of the 21st century. Despite being created to support the bitcoin, its applications go far beyond cryptocurrencies.
What is Blockchain?
Blockchain is a digital distributed ledger that records transactions in a secure, transparent, and immutable way. Imagine a shared notebook where everyone can write, but no one can erase what has been written.
How Does it Work?
- Blocks: Each transaction is grouped into a block
- Chain: The blocks are connected in chronological sequence
- Decentralization: Copies of the record exist on multiple computers
- Cryptography: Each block is protected by complex mathematical codes
Main Characteristics
- Immutability: Once recorded, it cannot be altered
- Transparency: Everyone can verify the transactions
- Security: Protected by advanced cryptography
- Decentralization: Not dependent on a central authority
