The #blockchain is like a public digital book 📖 that everyone can consult, but no one can secretly modify.

It is a technology for storing and transmitting information:

âžĄïž secure,

âžĄïž transparent,

âžĄïž and decentralized (it does not belong to a single entity).



🔄 How does it work?

✅ Each transaction is recorded in a "block" đŸ§©.

🔗 Blocks are linked together chronologically = block + chain.

🧠 The whole thing is validated by a network of computers (called nodes) through mechanisms like proof of work or proof of stake.

🔐 Once added, data cannot be modified. This is called immutability.



💡 Why is it important?

Because blockchain allows the creation of:

  • trustless systems without intermediaries (like banks or notaries),

  • direct exchanges between users (P2P),

  • open and verifiable ledgers for everyone.



đŸ‘¶ In summary:

Blockchain is a technological revolution that can transform finance, healthcare, administration, art, and much more... And it's not reserved for experts!
