📚 Lesson #2 – What Is Blockchain?

A blockchain is a digital ledger that records transactions across a network of computers.

Instead of relying on one central database, blockchain technology distributes the record across many participants in the network.

🔹 Transactions are grouped into blocks.
🔹 Each block is linked to the previous one.
🔹 The network verifies transactions through a consensus mechanism.
🔹 Once recorded, changing past data is designed to be difficult.
🔹 Anyone can verify activity on many public blockchains.

Blockchain technology is used for much more than cryptocurrencies. It can support digital assets, smart contracts, decentralized applications, and other systems.

💡 Key Takeaway:

A blockchain provides a shared and verifiable way to record digital transactions without requiring one central database to control the entire network.
