✅ What is Blockchain? (Clear Summary)

Blockchain is a decentralized digital ledger that stores information (such as transactions) in linked blocks, in an immutable and transparent manner.

Main characteristics:

Decentralization: no central authority (like a bank).

Immutability: data cannot be altered after being recorded.

Transparency: anyone can verify transactions.

Security: use of cryptography and distributed validation.

📌 How does it work?

1. User makes a transaction.

2. Transaction is grouped into a block.

3. The block is validated by nodes (computers) in the network.

4. The block is added to the chain of blocks (blockchain).

5. The transaction becomes public, secure, and permanent.

🧠 Types of Blockchain

Type Example Access

Public Bitcoin, Cardano Anyone can participate

Private Hyperledger, Corda Only authorized members

Hybrid Dragonchain Combines elements of both

🏗️ Blockchain Applications Beyond Cryptocurrencies

Smart Contracts – self-executing, as in Cardano and Ethereum.

Decentralized Finance (DeFi) – loans, exchanges without banks.

NFTs – registered digital art.

Logistics tracking – transparency in the supply chain.

Digital identity – secure user verification.

🎯 And what makes Cardano special?

Uses proof of stake (PoS), which consumes less energy than Bitcoin.

Based on peer-reviewed scientific research.

Supports smart contracts, like Ethereum.

Aims for scalability, interoperability, and sustainability.
