🧠 Summary:
Blocks store data and link to each other through cryptographic hashes.

Hashing ensures data can’t be tampered with.

PoW makes the network secure and decentralized.

Public and private blockchains serve different purposes.

 

📝 Workbook Activities:
Diagram a blockchain with 3 blocks, showing hashes and links.

Run a SHA-256 hash of your name online and paste the result.

Write one pro and one con of PoW and PoS.

Compare public vs. private blockchain use cases in a table.

Find and describe a real company using a private blockchain.
